These Highlights Do Not Include All The Information Needed To Use Suboxone Sublingual Film Safely And Effectively. See Full Prescribing Information For Suboxone Sublingual Film.

Inform patients and caregivers about opioid overdose reversal agents (e.g., naloxone, nalmefene) and discuss the importance of having access to an opioid overdose reversal agent. Because patients being treated for opioid use disorder have the potential for relapse, putting them at risk for opioid overdose, strongly consider recommending or prescribing an overdose reversal agent for the emergency treatment of opioid overdose, both when initiating and renewing treatment with SUBOXONE sublingual film. Also consider recommending or prescribing such an agent if the patient has household members (including children) or other close contacts at risk for accidental ingestion or opioid overdose [see Warnings and Precautions (5.2)].

Discuss the options for obtaining an opioid overdose reversal agent (e.g., prescription, over-the-counter, or as part of a community-based program) [see Warnings and Precautions (5.2)].

There are important differences among the opioid overdose reversal agents, such as route of administration, product strength, approved patient age range, and pharmacokinetics. Be familiar with these differences, as outlined in the approved labeling for those products, prior to recommending or prescribing such an agent.

Advise patients and caregivers that opioid overdose reversal agents, such as naloxone or nalmefene, may also be administered for a known or suspected overdose with buprenorphine itself. Higher than normal doses and repeated administration of an opioid overdose reversal agent may be necessary due to the long duration of action of buprenorphineand its affinity for the mu-opioid receptor [see Overdosage (10)].

INSTRUCTIONS FOR USE

SUBOXONE (Sub-OX-own) (buprenorphine and naloxone) Sublingual Film, CIII

This “Instructions for Use” contains information on how to correctly take SUBOXONE sublingual film.

Important Information You Need to Know Before Taking SUBOXONE sublingual film:

• Your healthcare provider should show you how to take SUBOXONE sublingual film the right way.
• Each SUBOXONE sublingual film comes in a sealed child‐resistant foil pouch. Do not open the foil pouch until you are ready to take it.

Preparing to take SUBOXONE sublingual film:

• To open your SUBOXONE sublingual film foil pouch, fold along the dotted line (see Figure 1).

  Figure 1

• Tear down at slit or cut with scissors along the arrow (see Figure 2).

  Figure 2

• Before taking SUBOXONE sublingual film, drink water to moisten your mouth. This helps the film dissolve more easily.

To take SUBOXONE sublingual film under your tongue (sublingual administration):

• Hold the film between two fingers by the outside edges.

• Place the SUBOXONE sublingual film under your tongue, close to the base either to the left or right of the center (see Figure 3).

  Figure 3

• If your healthcare provider tells you to take 2 films at a time, place the second film under your tongue on the opposite side. Avoid letting the films touch.
• Keep the films in place until they have completely dissolved.
• If your healthcare provider tells you to take a third film, place it under your tongue on either side after the first 2 films have dissolved.

To take SUBOXONE sublingual film on the inside of your cheek (buccal administration):

• Hold the film between two fingers by the outside edges.

• Place one film on the inside of your right or left cheek (see Figure 4).

  Figure 4

  • If your healthcare provider tells you to take 2 films at a time, place the other film on the inside of the opposite cheek.
  • Keep the films in place until they have completely dissolved.
  • If your healthcare provider tells you to take a third film, place it on the inside of your right or left cheek after the first 2 films have dissolved.
• While SUBOXONE sublingual film is dissolving, do not chew or swallow the film because the medicine will not work as well.
• Talking while the film is dissolving can affect how well the medicine in SUBOXONE sublingual film is absorbed.
• After SUBOXONE is completely dissolved, rinse your mouth with water and swallow. Wait for at least one hour before brushing teeth.
• If you miss a dose of SUBOXONE sublingual film, take your medicine when you remember. If it is almost time for your next dose, skip the missed dose and take the next dose at your regular time. Do not take 2 doses at the same time unless your healthcare provider tells you to. If you are not sure about your dosing, call your healthcare provider.
• Do not stop taking SUBOXONE sublingual film suddenly. You could become sick and have withdrawal symptoms because your body has become used to the medicine. Physical dependence is not the same as drug addiction. Your healthcare provider can tell you more about the differences between physical dependence and drug addiction. To have fewer withdrawal symptoms, ask your healthcare provider how to stop using SUBOXONE sublingual film the right way.

If you take too much SUBOXONE sublingual film or overdose, call Poison Control or get emergency medical help right away.

Storing SUBOXONE Sublingual Film:

• Store SUBOXONE sublingual film at room temperature between 68°F to 77°F (20°C to 25°C).
• Keep SUBOXONE sublingual film in a safe place, out of the sight and reach of children.

Disposing of SUBOXONE Sublingual Film:

• Dispose of unused SUBOXONE sublingual film as soon as you no longer need them.
• Dispose of expired, unwanted or unused SUBOXONE sublingual film by removing the SUBOXONE sublingual film from the foil packaging, and promptly flushing down the toilet (if a drug take-back option is not readily available). Do not flush the SUBOXONE sublingual film foil pouch down the toilet. Visit www.fda.gov/drugdisposal for additional information on disposal of unused medicines.

If you need help with disposal of SUBOXONE sublingual film, call 1‐877‐782‐6966.

Revised 06/2022

Before initiating treatment with SUBOXONE sublingual film, explain the points listed below to caregivers and patients. Instruct patients to read the Medication Guide each time SUBOXONE sublingual film is dispensed because new information may be available.

• SUBOXONE sublingual film must be administered whole. Advise patients not to cut, chew, or swallow SUBOXONE sublingual film.
• Inform patients and caregivers that potentially fatal additive effects may occur if SUBOXONE sublingual film is used with benzodiazepines or other CNS depressants (e.g., alcohol, non-benzodiazepine sedative/hypnotics, anxiolytics, tranquilizers, muscle relaxants, general anesthetics, antipsychotics, gabapentinoids [gabapentin or pregabalin], and other opioids) and not to use these concomitantly unless supervised by a healthcare provider [see Warnings and Precautions (5.2, 5.3), Drug Interactions (7)].
• Educate patients and caregivers on how to recognize respiratory depression and emphasize the importance of calling 911 or getting emergency medical help right away in the event of a known or suspected overdose [see Warnings and Precautions (5.2)].
• Patient Access to an Opioid Overdose Reversal Agent for the Emergency Treatment of Opioid Overdose
  
  Inform patients and caregivers about opioid overdose reversal agents (e.g., naloxone, nalmefene) and discuss the importance of having access to an opioid overdose reversal agent. Because patients being treated for opioid use disorder are at risk for relapse, discuss the importance of having access to an opioid overdose reversal agent. Also discuss the importance of having access to an opioid overdose reversal agent if there are household members (including children) or other close contacts at risk for accidental ingestion or opioid overdose.
  
  Discuss with the patient the options for obtaining an opioid overdose reversal agent (e.g., prescription, over-the-counter (some products), or as part of a community-based program) [see Dosage and Administration (2.2), Warnings and Precautions (5.2)].
  
  There are important differences among the opioid overdose reversal agents. Be familiar with these differences, as outlined in the approved labeling for those products, prior to recommending or prescribing such an agent.
  
  Educate patients and caregivers on how to recognize the signs and symptoms of an opioid overdose.
  
  Explain to patients and caregivers that effects of opioid overdose reversal agents like naloxone and nalmefene are temporary, and that they must call 911 or get emergency medical help right away in all cases of known or suspected opioid overdose, even if an opioid overdose reversal agent is administered. Repeat administration may be necessary, particularly for overdose involving buprenorphine [see Dosage and Administration (2.2), Warnings and Precautions (5.2), Overdosage (10)].
  
  Advise patients and caregivers:
  • how to treat with an opioid overdose reversal agent in the event of an opioid overdose.
  • to tell family and friends about their opioid overdose reversal agent, and to keep it in a place where family and friends can easily access it in an emergency.
  • to read the Patient Information (or other educational material) that will come with their opioid overdose reversal agent. Emphasize the importance of doing this before an opioid emergency happens, so the patient and caregiver will know what to do.
• Advise patients that SUBOXONE sublingual film contains an opioid that can be a target for people who abuse prescription medications or street drugs. Caution patients to keep their films in a safe place, and to protect them from theft.
• Instruct patients to keep SUBOXONE sublingual film in a secure place, out of the sight and reach of children. Accidental or deliberate ingestion by a child may cause respiratory depression that can result in death. Advise patients to seek medical attention immediately if a child is exposed to SUBOXONE sublingual film.
• Inform patients that opioids could cause a rare but potentially life-threatening condition resulting from concomitant administration of serotonergic drugs. Warn patients of the symptoms of serotonin syndrome and to seek medical attention right away if symptoms develop. Instruct patients to inform their healthcare providers if they are taking, or plan to take serotonergic medications [see Drug Interactions (7)].
• Inform patients that opioids could cause adrenal insufficiency, a potentially life- threatening condition. Adrenal insufficiency may present with non-specific symptoms and signs such as nausea, vomiting, anorexia, fatigue, weakness, dizziness, and low blood pressure. Advise patients to seek medical attention if they experience a constellation of these symptoms [see Warnings and Precautions (5.6)].
• Advise patients to never give SUBOXONE sublingual film to anyone else, even if he or she has the same signs and symptoms. It may cause harm or death.
• Advise patients that selling or giving away this medication is against the law.
• Advise patients that, after SUBOXONE has completely dissolved in the oral mucosa, to take a sip of water, swish it gently around their teeth and gums, and swallow. Advise patients to wait for at least one hour after taking SUBOXONE before brushing teeth [see Warnings and Precautions (5.13)].
• Refer patients to dental care services and encourage them to have regular dental checkups while taking SUBOXONE. Instruct patients to inform their dentist that they have started therapy on SUBOXONE [see Warnings and Precautions (5.13)].
• Caution patients that SUBOXONE sublingual film may impair the mental or physical abilities required for the performance of potentially dangerous tasks such as driving or operating machinery. Caution should be taken especially during drug induction and dose adjustment and until individuals are reasonably certain that buprenorphine therapy does not adversely affect their ability to engage in such activities [see Warnings and Precautions (5.15)].
• Advise patients not to change the dosage of SUBOXONE sublingual film without consulting their healthcare provider.
• Advise patients to take SUBOXONE sublingual film once a day.
• Advise patients that if they miss a dose of SUBOXONE sublingual film they should take it as soon as they remember. If it is almost time for the next dose, they should skip the missed dose and take the next dose at the regular time.
• Inform patients that SUBOXONE sublingual film can cause drug dependence and that withdrawal signs and symptoms may occur when the medication is discontinued.
• Advise patients seeking to discontinue treatment with buprenorphine for opioid dependence to work closely with their healthcare provider on a tapering schedule and inform them of the potential to relapse to illicit drug use associated with discontinuation of opioid agonist/partial agonist medication-assisted treatment.
• Advise patients that, like other opioids, SUBOXONE sublingual film may produce orthostatic hypotension in ambulatory individuals [see Warnings and Precautions (5.16)].
• Advise patients to inform their healthcare provider if any other prescription medications, over-the-counter medications, or herbal preparations are prescribed or currently being used [see Drug Interactions (7)].
• Advise women that if they are pregnant while being treated with SUBOXONE sublingual film, the baby may have signs of withdrawal at birth and that withdrawal is treatable [see Warnings and Precautions (5.5), Use in Specific Populations (8.1)].
• Advise women who are breastfeeding to monitor the infant for drowsiness and difficulty breathing [see Use in Specific Populations (8.2)].
• Inform patients that chronic use of opioids may cause reduced fertility. It is not known whether these effects on fertility are reversible [see Use in Specific Populations (8.3)].
• Advise patients to inform their family members that, in the event of emergency, the treating healthcare provider or emergency room staff should be informed that the patient is physically dependent on an opioid and that the patient is being treated with SUBOXONE sublingual film.

Buprenorphine, like morphine and other opioids, has the potential for being abused and is subject to criminal diversion. This should be considered when prescribing or dispensing buprenorphine in situations when the clinician is concerned about an increased risk of misuse, abuse, or diversion. Healthcare professionals should contact their state professional licensing board or state controlled substances authority for information on how to prevent and detect abuse or diversion of this product.

Patients who continue to misuse, abuse, or divert buprenorphine products or other opioids should be provided with or referred for more intensive and structured treatment.

Abuse of buprenorphine poses a risk of overdose and death. This risk is increased with the abuse of buprenorphine and alcohol and other substances, especially benzodiazepines.

The healthcare provider may be able to more easily detect misuse or diversion by maintaining records of medication prescribed including date, dose, quantity, frequency of refills, and renewal requests of medication prescribed.

Proper assessment of the patient, proper prescribing practices, periodic re-evaluation of therapy, and proper handling and storage of the medication are appropriate measures that help to limit abuse of opioid drugs.

Prior to induction, consideration should be given to the type of opioid dependence (i.e., long‐ or short‐acting opioid products), the time since last opioid use, and the degree or level of opioid dependence.

Patients dependent on heroin or other short‐acting opioid products

Patients dependent on heroin or other short‐acting opioid products may be inducted with either SUBOXONE sublingual film or with sublingual buprenorphine monotherapy. At treatment initiation, the first dose of SUBOXONE sublingual film should be administered when objective signs of moderate opioid withdrawal appear, not less than six hours after the patient last used opioids.

It is recommended that an adequate treatment dose, titrated to clinical effectiveness, be achieved as rapidly as possible. In some studies, a too‐gradual induction over several days led to a high rate of drop‐out of buprenorphine patients during the induction period.

On Day 1, an induction dosage of up to 8 mg/2 mg SUBOXONE sublingual film is recommended. Clinicians should start with an initial dose of 2 mg/0.5 mg or 4 mg/1 mg buprenorphine/naloxone and may titrate upwards in 2 or 4 mg increments of buprenorphine, at approximately 2‐hour intervals, under supervision, to 8 mg/2 mg buprenorphine/naloxone based on the control of acute withdrawal symptoms.

On Day 2, a single daily dose of up to 16 mg/4 mg SUBOXONE sublingual film is recommended.

Because the exposure to naloxone is somewhat higher after buccal than after sublingual administration, it is recommended that the sublingual site of administration be used during induction to minimize exposure to naloxone, to reduce the risk of precipitated withdrawal.

Patients dependent on methadone or long‐acting opioid products

Patients dependent upon methadone or long‐acting opioid products may be more susceptible to precipitated and prolonged withdrawal during induction than those on short‐acting opioid products.

Buprenorphine/naloxone combination products have not been evaluated in adequate and well‐controlled studies for induction in patients who are physically dependent on long‐acting opioid products, and the naloxone in these combination products is absorbed in small amounts by the sublingual route and could cause worse precipitated and prolonged withdrawal. For this reason, buprenorphine monotherapy is recommended in patients taking long‐acting opioids when used according to approved administration instructions. Following induction, the patient may then be transitioned to once‐daily SUBOXONE sublingual film.

SUBOXONE® (buprenorphine and naloxone) sublingual film is an orange film, imprinted with a logo identifying the product and strength in white ink. It contains buprenorphine HCl, a mu-opioid receptor partial agonist, and a kappa-opioid receptor antagonist, and naloxone HCl dihydrate, an opioid antagonist, at a ratio of 4:1 (ratio of free bases). It is intended for sublingual or buccal administration and is available in four dosage strengths, 2 mg buprenorphine with 0.5 mg naloxone, 4 mg buprenorphine with 1 mg naloxone, 8 mg buprenorphine with 2 mg naloxone and 12 mg buprenorphine with 3 mg naloxone. Each film also contains polyethylene oxide, hydroxypropyl methylcellulose, maltitol, acesulfame potassium, lime flavor, citric acid, sodium citrate, FD&C yellow #6, and white ink.

Chemically, buprenorphine HCl is (2S)-2-[17-Cyclopropylmethyl-4,5α-epoxy-3-hydroxy-6-methoxy-6α,14- ethano-14α-morphinan-7α-yl]-3,3-dimethylbutan-2-ol hydrochloride. It has the following chemical structure:

Buprenorphine HCl has the molecular formula C₂₉H₄₁NO₄• HCl and the molecular weight is 504.10. It is a white or off-white crystalline powder, sparingly soluble in water, freely soluble in methanol, soluble in alcohol, and practically insoluble in cyclohexane.

Chemically, naloxone HCl dihydrate is 17-Allyl-4,5 α -epoxy-3, 14-dihydroxymorphinan-6-one hydrochloride dihydrate. It has the following chemical structure:

Naloxone hydrochloride dihydrate has the molecular formula C₁₉H₂₁NO₄• HCl • 2H₂O and the molecular weight is 399.87. It is a white to slightly off-white powder and is freely soluble in water, soluble in alcohol, and practically insoluble in toluene and ether.

Buprenorphine is a partial agonist at the mu-opioid receptor and chronic administration produces physical dependence of the opioid type, characterized by moderate withdrawal signs and symptoms upon abrupt discontinuation or rapid taper. The withdrawal syndrome is typically milder than seen with full agonists and may be delayed in onset [see Warnings and Precautions (5.7)].

Neonatal opioid withdrawal syndrome (NOWS) is an expected and treatable outcome of prolonged use of opioids during pregnancy [see Warnings and Precautions (5.5)].

• For maintenance, SUBOXONE sublingual film may be administered buccally or sublingually.
• The dosage of SUBOXONE sublingual film from Day 3 onwards should be progressively adjusted in increments/decrements of 2 mg/0.5 mg or 4 mg/1 mg buprenorphine/naloxone to a level that holds the patient in treatment and suppresses opioid withdrawal signs and symptoms.
• After treatment induction to the recommended dose of 16 mg/4 mg buprenorphine/naloxone per day, dosing should be further adjusted based on the individual patient and clinical response. The maintenance dose of SUBOXONE sublingual film is generally in the range of 4 mg/1 mg buprenorphine/naloxone to 24 mg/6 mg buprenorphine/naloxone per day. Dosages higher than 24 mg/6 mg daily have not been investigated in randomized clinical trials but may be appropriate for some patients.
• When determining the prescription quantity for unsupervised administration, consider the patient's level of stability, the security of his or her home situation, and other factors likely to affect the ability to manage supplies of take‐home medication.
• There is no maximum recommended duration of maintenance treatment. Patients may require treatment indefinitely and should continue for as long as patients are benefiting and the use of SUBOXONE sublingual film contributes to the intended treatment goals.

The safety and effectiveness of SUBOXONE sublingual film have not been established in pediatric patients. This product is not appropriate for the treatment of neonatal abstinence syndrome in neonates, because it contains naloxone, an opioid antagonist.

Clinical studies of SUBOXONE sublingual film, SUBOXONE sublingual tablets, or SUBUTEX sublingual tablets did not include sufficient numbers of subjects aged 65 and over to determine whether they responded differently than younger subjects. Other reported clinical experience has not identified differences in responses between the elderly and younger patients. Due to possible decreased hepatic, renal, or cardiac function and of concomitant disease or other drug therapy in geriatric patients, the decision to prescribe SUBOXONE sublingual film should be made cautiously in individuals 65 years of age or older and these patients should be monitored for signs and symptoms of toxicity or overdose.

SUBOXONE sublingual film is contraindicated in patients with a history of hypersensitivity to buprenorphine or naloxone as serious adverse reactions, including anaphylactic shock, have been reported [see Warnings and Precautions (5.9)].

The following serious adverse reactions are described elsewhere in the labeling:

• Addiction, Abuse, and Misuse [see Warnings and Precautions (5.1)]
• Respiratory and CNS Depression [see Warnings and Precautions (5.2), (5.3)]
• Neonatal Opioid Withdrawal Syndrome [see Warnings and Precautions (5.5)]
• Adrenal Insufficiency [see Warnings and Precautions (5.6)]
• Opioid Withdrawal [see Warnings and Precautions (5.7, 5.10)]
• Hepatitis, Hepatic Events [see Warnings and Precautions (5.8)]
• Hypersensitivity Reactions [see Warnings and Precautions (5.9)]
• Orthostatic Hypotension [see Warnings and Precautions (5.16)]
• Elevation of Cerebrospinal Fluid Pressure [see Warnings and Precautions (5.17)]
• Elevation of Intracholedochal Pressure [see Warnings and Precautions (5.18)]

Table 4 includes clinically significant drug interactions with SUBOXONE.

No differences in buprenorphine pharmacokinetics were observed between 9 dialysis-dependent and 6 normal patients following IV administration of 0.3 mg buprenorphine. The effects of renal failure on naloxone pharmacokinetics are unknown.

Because of the risks associated with accidental ingestion, misuse, and abuse, advise patients to store SUBOXONE sublingual film securely, out of sight and reach of children, and in a location not accessible by others, including visitors to the home [see Warnings and Precautions (5.1, 5.4), Drug Abuse and Dependence (9.2)]. Inform patients that leaving SUBOXONE sublingual film unsecured can pose a deadly risk to others in the home.

Advise patients and caregivers that when medicines are no longer needed, they should be disposed of promptly. Expired, unwanted, or unused SUBOXONE sublingual film should be disposed of by removing the SUBOXONE sublingual film from the foil packaging, and flushing the unused medication down the toilet (if a drug take-back option is not readily available). Inform patients that they can visit www.fda.gov/drugdisposal for a complete list of medicines recommended for disposal by flushing, as well as additional information on disposal of unused medicines.

Healthcare providers will need to decide when they cannot appropriately provide further management for particular patients. For example, some patients may be abusing or dependent on various drugs, or unresponsive to psychosocial intervention such that the healthcare provider does not feel that he/she has the expertise to manage the patient. In such cases, the healthcare provider may want to assess whether to refer the patient to a specialist or more intensive behavioral treatment environment. Decisions should be based on a treatment plan established and agreed upon with the patient at the beginning of treatment.

Patients who continue to misuse, abuse, or divert buprenorphine products or other opioids should be provided with, or referred to, more intensive and structured treatment.

Thorough QT studies with buprenorphine products have demonstrated QT prolongation ≤ 15 msec. This QTc prolongation effect does not appear to be mediated by hERG channels. Based on these two findings, buprenorphine is unlikely to be pro-arrhythmic when used alone in patients without risk factors. The risk of combining buprenorphine with other QT-prolonging agents is not known.

Consider these observations in clinical decisions when prescribing SUBOXONE sublingual film to patients with risk factors such as hypokalemia, bradycardia, recent conversion from atrial fibrillation, congestive heart failure, digitalis therapy, baseline QT prolongation, subclinical long-QT syndrome, or severe hypomagnesemia.

The effect of hepatic impairment on the pharmacokinetics of buprenorphine and naloxone has been evaluated in a pharmacokinetic study. Both drugs are extensively metabolized in the liver. While no clinically significant changes have been observed in subjects with mild hepatic impairment; the plasma levels have been shown to be higher and half-life values have been shown to be longer for both buprenorphine and naloxone in subjects with moderate and severe hepatic impairment. The magnitude of the effects on naloxone are greater than that on buprenorphine in both moderately and severely impaired subjects. The difference in magnitude of the effects on naloxone and buprenorphine are greater in subjects with severe hepatic impairment than in subjects with moderate hepatic impairment, and therefore the clinical impact of these effects is likely to be greater in patients with severe hepatic impairment than in patients with moderate hepatic impairment.

Buprenorphine/naloxone products should be avoided in patients with severe hepatic impairment and may not be appropriate for patients with moderate hepatic impairment [see Warnings and Precautions (5.12), Clinical Pharmacology (12.3)].

SUBOXONE sublingual film is indicated for treatment of opioid dependence. SUBOXONE sublingual film should be used as part of a complete treatment plan that includes counseling and psychosocial support.

SUBOXONE sublingual film contains buprenorphine and naloxone. Buprenorphine is a partial agonist at the mu-opioid receptor and an antagonist at the kappa-opioid receptor. Naloxone is a potent antagonist at mu opioid receptors and produces opioid withdrawal signs and symptoms in individuals physically dependent on full opioid agonists when administered parenterally.

Treatment should be initiated with supervised administration, progressing to unsupervised administration as the patient's clinical stability permits. SUBOXONE sublingual film is subject to diversion and abuse. When determining the prescription quantity for unsupervised administration, consider the patient's level of stability, the security of his or her home situation, and other factors likely to affect the ability to manage supplies of take‐home medication.

Ideally patients should be seen at reasonable intervals (e.g., at least weekly during the first month of treatment) based upon the individual circumstances of the patient. Medication should be prescribed in consideration of the frequency of visits. Provision of multiple refills is not advised early in treatment or without appropriate patient follow‐up visits. Periodic assessment is necessary to determine compliance with the dosing regimen, effectiveness of the treatment plan, and overall patient progress.

Once a stable dosage has been achieved and patient assessment (e.g., urine drug screening) does not indicate illicit drug use, less frequent follow‐up visits may be appropriate. A once‐monthly visit schedule may be reasonable for patients on a stable dosage of medication who are making progress toward their treatment objectives. Continuation or modification of pharmacotherapy should be based on the healthcare provider's evaluation of treatment outcomes and objectives such as:

• Absence of medication toxicity.
• Absence of medical or behavioral adverse effects.
• Responsible handling of medications by the patient.
• Patient's compliance with all elements of the treatment plan (including recovery‐oriented activities, psychotherapy, and/or other psychosocial modalities).
• Abstinence from illicit drug use (including problematic alcohol and/or benzodiazepine use).

If treatment goals are not being achieved, the healthcare provider should re‐evaluate the appropriateness of continuing the current treatment.

SUBOXONE sublingual film contains buprenorphine, a Schedule III controlled substance under the Controlled Substances Act.

Cases of adrenal insufficiency have been reported with opioid use, more often following greater than one month of use. Presentation of adrenal insufficiency may include non‐specific symptoms and signs including nausea, vomiting, anorexia, fatigue, weakness, dizziness, and low blood pressure. If adrenal insufficiency is suspected, confirm the diagnosis with diagnostic testing as soon as possible. If adrenal insufficiency is diagnosed, treat with physiologic replacement doses of corticosteroids. Wean the patient off of the opioid to allow adrenal function to recover and continue corticosteroid treatment until adrenal function recovers. Other opioids may be tried as some cases reported use of a different opioid without recurrence of adrenal insufficiency. The information available does not identify any particular opioids as being more likely to be associated with adrenal insufficiency.

• Addiction, Abuse, and Misuse: Buprenorphine can be abused in a similar manner to other opioids. Monitor patients for conditions indicative of diversion or progression of opioid dependence and addictive behaviors. Multiple refills should not be prescribed early in treatment or without appropriate patient follow-up visits. (5.1)
• Respiratory Depression: Life-threatening respiratory depression and death have occurred in association with buprenorphine use. Warn patients of the potential danger of self-administration of benzodiazepines or other CNS depressants while under treatment with SUBOXONE sublingual film. (5.2, 5.3)
• Unintentional Pediatric Exposure: Store SUBOXONE sublingual film safely out of the sight and reach of children. Buprenorphine can cause severe, possibly fatal, respiratory depression in children. (5.4)
• Neonatal Opioid Withdrawal Syndrome: Neonatal opioid withdrawal syndrome (NOWS) is an expected and treatable outcome of prolonged use of opioids during pregnancy (5.5)
• Adrenal Insufficiency: If diagnosed, treat with physiologic replacement of corticosteroids, and wean patient off of the opioid. (5.6)
• Risk of Opioid Withdrawal with Abrupt Discontinuation: If treatment is temporarily interrupted or discontinued, monitor patients for withdrawal and treat appropriately. (5.7)
• Risk of Hepatitis, Hepatic Events: Monitor liver function tests prior to initiation and during treatment and evaluate suspected hepatic events. (5.8)
• Precipitation of Opioid Withdrawal Signs and Symptoms: An opioid withdrawal syndrome is likely to occur with parenteral misuse of SUBOXONE sublingual film by individuals physically dependent on full opioid agonists, or by sublingual or buccal administration before the agonist effects of other opioids have subsided. (5.10)
• Risk of Overdose in Opioid‐Naïve Patients: SUBOXONE sublingual film is not appropriate as an analgesic. There have been reported deaths of opioid naïve individuals who received a 2 mg sublingual dose. (5.11)

Cases of dental caries, some severe (i.e., tooth fracture, tooth loss), have been reported following the use of transmucosal buprenorphine-containing products. Reported events include cavities, tooth decay, dental abscesses/infection, rampant caries, tooth erosion, fillings falling out, and, in some cases, total tooth loss. Treatment for these events included tooth extraction, root canal, dental surgery, as well as other restorative procedures (i.e., fillings, crowns, implants, dentures). Multiple cases were reported in individuals without any prior history of dental problems.

Refer patients to dental care services and encourage them to have regular dental checkups while taking SUBOXONE. Educate patients to seek dental care and strategies to maintain or improve oral health while being treated with transmucosal buprenorphine-containing products. Strategies include, but are not limited to, gently rinsing the teeth and gums with water and then swallowing after SUBOXONE has been completely dissolved in the oral mucosa. Advise patients to wait for at least one hour after taking SUBOXONE before brushing teeth [see Dosing and Administration (2.5), Information for Patients (17), Medication Guide].

• Administer SUBOXONE sublingual film as a single daily dose. (2.1)
• Strongly consider recommending or prescribing an opioid overdose reversal agent (e.g., naloxone, nalmefene) at the time SUBOXONE sublingual film is initiated or renewed because patients being treated for opioid use disorder have the potential for relapse, putting them at risk for opioid overdose. (2.2)
• To avoid precipitating withdrawal, induction with SUBOXONE sublingual film should be undertaken when objective and clear signs of withdrawal are evident and SUBOXONE sublingual film should be administered in divided doses when used as initial treatment. (2.3)
• For patients dependent on short‐acting opioid products who are in opioid withdrawal; on Day 1, administer up to 8 mg/2 mg SUBOXONE sublingual film (in divided doses). On Day 2, administer up to 16 mg/4 mg of SUBOXONE sublingual film as a single dose. (2.3)
• For patients dependent on methadone or long‐acting opioid products, induction onto sublingual buprenorphine monotherapy is recommended on Days 1 and 2 of treatment. (2.3)
• The maintenance dose of SUBOXONE sublingual film is generally in the range of 4 mg/1 mg to 24 mg/6 mg per day and should be based on clinical response. (2.4)
• Sublingual Administration: Place one film under the tongue, close to the base on the left or right side, and allow to completely dissolve. Buccal Administration: Place one film on the inside of the left or right cheek and allow to completely dissolve. (2.5)
• SUBOXONE sublingual film must be administered whole. Do not cut, chew, or swallow SUBOXONE sublingual film (2.5)
• When discontinuing treatment, gradually taper to avoid signs and symptoms of withdrawal. (2.8)

The decision to discontinue therapy with SUBOXONE sublingual film after a period of maintenance should be made as part of a comprehensive treatment plan. Advise patients of the potential to relapse to illicit drug use following discontinuation of opioid agonist/partial agonist medication‐assisted treatment. Taper patients to reduce the occurrence of opioid withdrawal signs and symptoms [See Warnings and Precautions (5.7)].

SUBOXONE sublingual film must be administered whole. Do not cut, chew, or swallow SUBOXONE sublingual film. Advise patients not to eat or drink anything until the film is completely dissolved.

SUBOXONE sublingual film is supplied as an orange rectangular film with a white printed logo in four dosage strengths:

• Buprenorphine 2 mg/naloxone 0.5 mg,
• Buprenorphine 4 mg/naloxone 1 mg,
• Buprenorphine 8 mg/naloxone 2 mg and
• Buprenorphine 12 mg/naloxone 3 mg

Like other opioids, SUBOXONE sublingual film may produce orthostatic hypotension in ambulatory patients.

The following adverse reactions have been identified during post-approval use of SUBOXONE sublingual film. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure.

The most frequently reported postmarketing adverse events were peripheral edema, stomatitis, glossitis, and blistering and ulceration of the mouth or tongue.

Serotonin syndrome: Cases of serotonin syndrome, a potentially life-threatening condition, have been reported during concomitant use of opioids with serotonergic drugs.

Adrenal insufficiency: Cases of adrenal insufficiency have been reported with opioid use, more often following greater than one month of use.

Anaphylaxis: Anaphylaxis has been reported with ingredients contained in SUBOXONE sublingual film.

Androgen deficiency: Cases of androgen deficiency have occurred with chronic use of opioids [see Clinical Pharmacology (12.2)].

Local reactions: Dental decay (including caries, tooth fracture, and tooth loss), glossodynia, glossitis, oral mucosal erythema, oral hypoesthesia, and stomatitis

Hypoglycemia: Cases of hypoglycemia have been reported in patients taking opioids. Most reports were in patients with at least one predisposing risk factor (e.g., diabetes).

Opioid-induced esophageal dysfunction (OIED): Cases of OIED have been reported in patients taking opioids and may occur more frequently in patients taking higher doses of opioids, and/or in patients taking opioids longer term.

• Lactation: Buprenorphine passes into mother's milk. (8.2)
• Geriatric Patients: Monitor for sedation and respiratory depression. (8.5)
• Moderate or Severe Hepatic Impairment: Buprenorphine/naloxone products are not recommended in patients with severe hepatic impairment and may not be appropriate for patients with moderate hepatic impairment. (8.6)

Cases of hypersensitivity to buprenorphine and naloxone containing products have been reported both in clinical trials and in the post‐marketing experience. Cases of bronchospasm, angioneurotic edema, and anaphylactic shock have been reported. The most common signs and symptoms include rashes, hives, and pruritus. A history of hypersensitivity to buprenorphine or naloxone is a contraindication to the use of SUBOXONE sublingual film.

Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice.

The safety of SUBOXONE sublingual film is supported by clinical trials using SUBUTEX® (buprenorphine) sublingual tablets and SUBOXONE (buprenorphine and naloxone) sublingual tablets, and other trials using buprenorphine sublingual solutions, as well as an open-label study in 194 patients treated with SUBOXONE sublingual film administered sublingually and 188 patients treated with the film administered buccally. In total, safety data from clinical studies are available from over 3000 opioid-dependent subjects exposed to buprenorphine at doses in the range used in the treatment of opioid dependence. Few differences in the adverse event profile were noted with regard to sublingually and bucally administered SUBOXONE sublingual film, SUBOXONE sublingual tablets, SUBUTEX sublingual tablets and a buprenorphine ethanolic sublingual solution.

The most common adverse event (> 1%) associated with the sublingual administration of the SUBOXONE sublingual film was oral hypoesthesia. Other adverse events were constipation, glossodynia, oral mucosal erythema, vomiting, intoxication, disturbance in attention, palpitations, insomnia, withdrawal syndrome, hyperhidrosis, and blurred vision.

The most common adverse events associated with the buccal administration were similar to those observed with sublingual administration of the film.

Other adverse event data were derived from larger, controlled studies of SUBOXONE sublingual tablets and SUBUTEX sublingual tablets and of buprenorphine sublingual solution. In a comparative study of SUBOXONE sublingual tablets and SUBUTEX sublingual tablets, adverse event profiles were similar for subjects treated with 16 mg/4 mg SUBOXONE sublingual tablets or 16 mg SUBUTEX sublingual tablets. The following adverse events were reported to occur by at least 5% of patients in a 4 week study of SUBOXONE sublingual tablets and SUBUTEX sublingual tablets.

The adverse event profile of buprenorphine was also characterized in the dose-controlled study of a buprenorphine ethanolic solution, over a range of doses in four months of treatment. Table 3 shows adverse events reported by at least 5% of subjects in any dose group in the dose-controlled trial.

The safety of SUBOXONE sublingual film during treatment induction is supported by a clinical trial using 16 patients treated with SUBOXONE sublingual film and 18 treated with a buprenorphine-only sublingual film. Few differences in the adverse event profiles were noted between SUBOXONE sublingual film and the buprenorphine-only sublingual film.

The most common adverse event occurring during treatment induction and the 3 days following induction using SUBOXONE sublingual film was restlessness. Other adverse events were anxiety, piloerection, stomach discomfort, irritability, headache, rhinorrhea, cold sweat, arthralgia, and lacrimation increased.

Four subjects left the study early on the first day of sublingual film administration. However, there was no evidence to suggest that any of the four subjects experienced precipitated withdrawal secondary to the administration of buprenorphine or buprenorphine/naloxone sublingual films.

SUBOXONE sublingual film contains buprenorphine, a schedule III controlled substance that can be abused in a manner similar to other opioids, legal or illicit. Prescribe and dispense buprenorphine with appropriate precautions to minimize risk of misuse, abuse, or diversion, and ensure appropriate protection from theft, including in the home. Clinical monitoring appropriate to the patient's level of stability is essential. Multiple refills should not be prescribed early in treatment or without appropriate patient follow‐up visits [see Drug Abuse and Dependence (9.2)].

Advise patients to read the FDA-approved patient labeling (Medication Guide).

Buprenorphine can cause severe, possibly fatal, respiratory depression in children who are accidentally exposed to it. Store buprenorphine‐containing medications safely out of the sight and reach of children and destroy any unused medication appropriately [see Patient Counseling Information (17)].

Cases of cytolytic hepatitis and hepatitis with jaundice have been observed in individuals receiving buprenorphine in clinical trials and through post‐marketing adverse event reports. The spectrum of abnormalities ranges from transient asymptomatic elevations in hepatic transaminases to case reports of death, hepatic failure, hepatic necrosis, hepatorenal syndrome, and hepatic encephalopathy. In many cases, the presence of pre‐existing liver enzyme abnormalities, infection with hepatitis B or hepatitis C virus, concomitant usage of other potentially hepatotoxic drugs, and ongoing injecting drug use may have played a causative or contributory role. In other cases, insufficient data were available to determine the etiology of the abnormality. Withdrawal of buprenorphine has resulted in amelioration of acute hepatitis in some cases; however, in other cases no dose reduction was necessary. The possibility exists that buprenorphine had a causative or contributory role in the development of the hepatic abnormality in some cases. Liver function tests, prior to initiation of treatment, are recommended to establish a baseline. Periodic monitoring of liver function during treatment is also recommended. A biological and etiological evaluation is recommended when a hepatic event is suspected. Depending on the case, SUBOXONE sublingual film may need to be carefully discontinued to prevent withdrawal signs and symptoms and a return by the patient to illicit drug use, and strict monitoring of the patient should be initiated.

SUBOXONE sublingual film is supplied as an orange rectangular film with a white printed logo in child-resistant polyester/foil laminated pouches:

• NDC 12496-1202-3 (buprenorphine 2 mg/naloxone 0.5 mg/film; content expressed in terms of free base, equivalent to 2.16 mg buprenorphine hydrochloride USP and 0.61 mg naloxone hydrochloride dihydrate USP) - 30 films per carton

Store at 25°C (77°F), excursions permitted to 15-30°C (59-86°F) [see USP Controlled Room Temperature].

Store SUBOXONE sublingual film securely and dispose of properly [see Patient Counseling Information (17)].

Neonatal opioid withdrawal syndrome (NOWS) is an expected and treatable outcome of prolonged use of opioids during pregnancy, whether that use is medically‐authorized or illicit. Unlike opioid withdrawal syndrome in adults, NOWS may be life‐threatening if not recognized and treated in the neonate. Healthcare professionals should observe newborns for signs of NOWS and manage accordingly [see Use in Specific Populations (8.1)].

Advise pregnant women receiving opioid addiction treatment with SUBOXONE sublingual film of the risk of neonatal opioid withdrawal syndrome and ensure that appropriate treatment will be available [see Use in Specific Populations (8.1)]. This risk must be balanced against the risk of untreated opioid addiction which often results in continued or relapsing illicit opioid use and is associated with poor pregnancy outcomes. Therefore, prescribers should discuss the importance and benefits of management of opioid addiction throughout pregnancy.

As with other opioids, buprenorphine may obscure the diagnosis or clinical course of patients with acute abdominal conditions.

Buprenorphine has been shown to increase intracholedochal pressure, as do other opioids, and thus should be administered with caution to patients with dysfunction of the biliary tract.

Buprenorphine, like other opioids, may elevate cerebrospinal fluid pressure and should be used with caution in patients with head injury, intracranial lesions, and other circumstances when cerebrospinal pressure may be increased. Buprenorphine can produce miosis and changes in the level of consciousness that may interfere with patient evaluation.

There have been reported deaths of opioid ‐naïve individuals who received a 2 mg dose of buprenorphine as a sublingual tablet for analgesia. SUBOXONE sublingual film is not appropriate as an analgesic.

SUBOXONE sublingual film is administered sublingually or buccally as a single daily dose.

Medication should be prescribed in consideration of the frequency of visits. Provision of multiple refills is not advised early in treatment or without appropriate patient follow‐up visits.

Buprenorphine/naloxone products are not recommended in patients with severe hepatic impairment and may not be appropriate for patients with moderate hepatic impairment. The doses of buprenorphine and naloxone in this fixed‐dose combination product cannot be individually titrated, and hepatic impairment results in a reduced clearance of naloxone to a much greater extent than buprenorphine. Therefore, patients with severe hepatic impairment will be exposed to substantially higher levels of naloxone than patients with normal hepatic function. This may result in an increased risk of precipitated withdrawal at the beginning of treatment (induction) and may interfere with buprenorphine's efficacy throughout treatment. In patients with moderate hepatic impairment, the differential reduction of naloxone clearance compared to buprenorphine clearance is not as great as in subjects with severe hepatic impairment. However, buprenorphine/naloxone products are not recommended for initiation of treatment (induction) in patients with moderate hepatic impairment due to the increased risk of precipitated withdrawal. Buprenorphine/naloxone products may be used with caution for maintenance treatment in patients with moderate hepatic impairment who have initiated treatment on a buprenorphine product without naloxone. However, patients should be carefully monitored and consideration given to the possibility of naloxone interfering with buprenorphine's efficacy [see Use in Specific Populations (8.6)].

SUBOXONE sublingual film may impair the mental or physical abilities required for the performance of potentially dangerous tasks such as driving a car or operating machinery, especially during treatment induction and dose adjustment. Caution patients about driving or operating hazardous machinery until they are reasonably certain that SUBOXONE sublingual film therapy does not adversely affect his or her ability to engage in such activities.

As indicated in Table 1, the sizes and the compositions of the four units of SUBOXONE sublingual films, i.e., 2 mg/0.5 mg, 4 mg/1 mg, 8 mg/2 mg and the 12 mg/3 mg units, are different from one another. If patients switch between various combinations of lower and higher strength units of SUBOXONE sublingual films to obtain the same total dose, (e.g., from three 4 mg/1 mg units to a single 12 mg/3 mg unit, or vice‐versa), systemic exposures of buprenorphine and naloxone may be different and patients should be monitored for over‐dosing or under‐dosing. For this reason, pharmacist should not substitute one or more film strengths for another without approval of the prescriber.

Buprenorphine is a partial agonist at the mu‐opioid receptor and chronic administration produces physical dependence of the opioid type, characterized by withdrawal signs and symptoms upon abrupt discontinuation or rapid taper. The withdrawal syndrome is typically milder than seen with full agonists and may be delayed in onset [see Drug Abuse and Dependence (9.3)]. When discontinuing SUBOXONE sublingual film, gradually taper the dosage [see Dosage and Administration (2.8)].

Because it contains naloxone, SUBOXONE sublingual film is likely to produce withdrawal signs and symptoms if misused parenterally by individuals dependent on full opioid agonists such as heroin, morphine, or methadone. Because of the partial agonist properties of buprenorphine, SUBOXONE sublingual film may precipitate opioid withdrawal signs and symptoms in such persons if administered before the agonist effects of the opioid have subsided.

The systemic exposure of buprenorphine between buccal and sublingual administration of SUBOXONE sublingual film is similar. Therefore, once induction is complete, patients can switch between buccal and sublingual administration without significant risk of under or overdosing.

Concomitant use of buprenorphine and benzodiazepines and/or other CNS depressants (e.g., alcohol, non-benzodiazepine sedative/hypnotics, anxiolytics, tranquilizers, muscle relaxants, general anesthetics, antipsychotics, gabapentinoids [gabapentin or pregabalin], and other opioids) increases the risk of adverse reactions including overdose, respiratory depression, and death. Medication-assisted treatment of opioid use disorder, however, should not be categorically denied to patients taking these drugs. Prohibiting or creating barriers to treatment can pose an even greater risk of morbidity and mortality due to the opioid use disorder alone.

As a routine part of orientation to buprenorphine treatment, educate patients about the risks of concomitant use of benzodiazepines, sedatives, opioid analgesics, and alcohol.

Develop strategies to manage use of prescribed or illicit benzodiazepines or other CNS depressants at initiation of buprenorphine treatment, or if it emerges as a concern during treatment. Adjustments to induction procedures and additional monitoring may be required. There is no evidence to support dose limitations or arbitrary caps of buprenorphine as a strategy to address benzodiazepine use in buprenorphine‐treated patients. However, if a patient is sedated at the time of buprenorphine dosing, delay or omit the buprenorphine dose if appropriate.

Cessation of benzodiazepines or other CNS depressants is preferred in most cases of concomitant use. In some cases, monitoring in a higher level of care for taper may be appropriate. In others, gradually tapering a patient off of a prescribed benzodiazepine or other CNS depressant or decreasing to the lowest effective dose may be appropriate.

For patients in buprenorphine treatment, benzodiazepines are not the treatment of choice for anxiety or insomnia. Before co‐prescribing benzodiazepines, ensure that patients are appropriately diagnosed and consider alternative medications and non‐pharmacologic treatments to address anxiety or insomnia. Ensure that other healthcare providers prescribing benzodiazepines or other CNS depressants are aware of the patient's buprenorphine treatment and coordinate care to minimize the risks associated with concomitant use.

If concomitant use is warranted, strongly consider recommending or prescribing an opioid overdose reversal agent, as is recommended for all patients on buprenorphine treatment for opioid use disorder [see Warnings and Precautions (5.2)].

In addition, take measures to confirm that patients are taking their medications as prescribed and are not diverting or supplementing with illicit drugs. Toxicology screening should test for prescribed and illicit benzodiazepines [see Drug Interactions (7)].

Buprenorphine has been associated with life‐threatening respiratory depression and death. Many, but not all, postmarketing reports regarding coma and death involved misuse by self‐injection or were associated with the concomitant use of buprenorphine and benzodiazepines or other CNS depressants, including alcohol. Warn patients of the potential danger of self‐administration of benzodiazepines or other CNS depressants while under treatment with SUBOXONE sublingual film [see Warnings and Precautions (5.3), Drug Interactions (7)].

Use SUBOXONE sublingual film with caution in patients with compromised respiratory function (e.g., chronic obstructive pulmonary disease, cor pulmonale, decreased respiratory reserve, hypoxia, hypercapnia, or pre-existing respiratory depression).

Educate patients and caregivers on how to recognize respiratory depression and emphasize the importance of calling 911 or getting emergency medical help right away in the event of a known or suspected overdose [see Patient Counseling Information (17)].

Opioids can cause sleep-related breathing disorders including central sleep apnea (CSA) and sleep-related hypoxemia. Opioid use increases the risk of CSA in a dose-dependent fashion. In patients who present with CSA, consider decreasing the opioid dosage using best practices for opioid taper [see Dosage and Administration (2.8)].

Patients being switched between buprenorphine and naloxone or buprenorphine only sublingual tablets and SUBOXONE sublingual film should be started on the same dosage of the previously administered product. However, dosage adjustments may be necessary when switching between buprenorphine products. Not all strengths and combinations of the SUBOXONE sublingual films are bioequivalent to SUBOXONE® sublingual tablets as observed in pharmacokinetic studies [see Clinical Pharmacology (12.3)]. Therefore, systemic exposures of buprenorphine and naloxone may be different when patients are switched from tablets to film or vice‐versa. Patients should be monitored for symptoms related to over‐dosing or under‐dosing.

Inform patients and caregivers about opioid overdose reversal agents (e.g., naloxone, nalmefene) and discuss the importance of having access to an opioid overdose reversal agent. Because patients being treated for opioid use disorder have the potential for relapse, putting them at risk for opioid overdose, strongly consider recommending or prescribing an overdose reversal agent for the emergency treatment of opioid overdose, both when initiating and renewing treatment with SUBOXONE sublingual film. Also consider recommending or prescribing such an agent if the patient has household members (including children) or other close contacts at risk for accidental ingestion or opioid overdose [see Warnings and Precautions (5.2)].

Discuss the options for obtaining an opioid overdose reversal agent (e.g., prescription, over-the-counter, or as part of a community-based program) [see Warnings and Precautions (5.2)].

There are important differences among the opioid overdose reversal agents, such as route of administration, product strength, approved patient age range, and pharmacokinetics. Be familiar with these differences, as outlined in the approved labeling for those products, prior to recommending or prescribing such an agent.

Advise patients and caregivers that opioid overdose reversal agents, such as naloxone or nalmefene, may also be administered for a known or suspected overdose with buprenorphine itself. Higher than normal doses and repeated administration of an opioid overdose reversal agent may be necessary due to the long duration of action of buprenorphineand its affinity for the mu-opioid receptor [see Overdosage (10)].

INSTRUCTIONS FOR USE

SUBOXONE (Sub-OX-own) (buprenorphine and naloxone) Sublingual Film, CIII

This “Instructions for Use” contains information on how to correctly take SUBOXONE sublingual film.

Important Information You Need to Know Before Taking SUBOXONE sublingual film:

• Your healthcare provider should show you how to take SUBOXONE sublingual film the right way.
• Each SUBOXONE sublingual film comes in a sealed child‐resistant foil pouch. Do not open the foil pouch until you are ready to take it.

Preparing to take SUBOXONE sublingual film:

• To open your SUBOXONE sublingual film foil pouch, fold along the dotted line (see Figure 1).

  Figure 1

• Tear down at slit or cut with scissors along the arrow (see Figure 2).

  Figure 2

• Before taking SUBOXONE sublingual film, drink water to moisten your mouth. This helps the film dissolve more easily.

To take SUBOXONE sublingual film under your tongue (sublingual administration):

• Hold the film between two fingers by the outside edges.

• Place the SUBOXONE sublingual film under your tongue, close to the base either to the left or right of the center (see Figure 3).

  Figure 3

• If your healthcare provider tells you to take 2 films at a time, place the second film under your tongue on the opposite side. Avoid letting the films touch.
• Keep the films in place until they have completely dissolved.
• If your healthcare provider tells you to take a third film, place it under your tongue on either side after the first 2 films have dissolved.

To take SUBOXONE sublingual film on the inside of your cheek (buccal administration):

• Hold the film between two fingers by the outside edges.

• Place one film on the inside of your right or left cheek (see Figure 4).

  Figure 4

  • If your healthcare provider tells you to take 2 films at a time, place the other film on the inside of the opposite cheek.
  • Keep the films in place until they have completely dissolved.
  • If your healthcare provider tells you to take a third film, place it on the inside of your right or left cheek after the first 2 films have dissolved.
• While SUBOXONE sublingual film is dissolving, do not chew or swallow the film because the medicine will not work as well.
• Talking while the film is dissolving can affect how well the medicine in SUBOXONE sublingual film is absorbed.
• After SUBOXONE is completely dissolved, rinse your mouth with water and swallow. Wait for at least one hour before brushing teeth.
• If you miss a dose of SUBOXONE sublingual film, take your medicine when you remember. If it is almost time for your next dose, skip the missed dose and take the next dose at your regular time. Do not take 2 doses at the same time unless your healthcare provider tells you to. If you are not sure about your dosing, call your healthcare provider.
• Do not stop taking SUBOXONE sublingual film suddenly. You could become sick and have withdrawal symptoms because your body has become used to the medicine. Physical dependence is not the same as drug addiction. Your healthcare provider can tell you more about the differences between physical dependence and drug addiction. To have fewer withdrawal symptoms, ask your healthcare provider how to stop using SUBOXONE sublingual film the right way.

If you take too much SUBOXONE sublingual film or overdose, call Poison Control or get emergency medical help right away.

Storing SUBOXONE Sublingual Film:

• Store SUBOXONE sublingual film at room temperature between 68°F to 77°F (20°C to 25°C).
• Keep SUBOXONE sublingual film in a safe place, out of the sight and reach of children.

Disposing of SUBOXONE Sublingual Film:

• Dispose of unused SUBOXONE sublingual film as soon as you no longer need them.
• Dispose of expired, unwanted or unused SUBOXONE sublingual film by removing the SUBOXONE sublingual film from the foil packaging, and promptly flushing down the toilet (if a drug take-back option is not readily available). Do not flush the SUBOXONE sublingual film foil pouch down the toilet. Visit www.fda.gov/drugdisposal for additional information on disposal of unused medicines.

If you need help with disposal of SUBOXONE sublingual film, call 1‐877‐782‐6966.

Revised 06/2022

Before initiating treatment with SUBOXONE sublingual film, explain the points listed below to caregivers and patients. Instruct patients to read the Medication Guide each time SUBOXONE sublingual film is dispensed because new information may be available.

• SUBOXONE sublingual film must be administered whole. Advise patients not to cut, chew, or swallow SUBOXONE sublingual film.
• Inform patients and caregivers that potentially fatal additive effects may occur if SUBOXONE sublingual film is used with benzodiazepines or other CNS depressants (e.g., alcohol, non-benzodiazepine sedative/hypnotics, anxiolytics, tranquilizers, muscle relaxants, general anesthetics, antipsychotics, gabapentinoids [gabapentin or pregabalin], and other opioids) and not to use these concomitantly unless supervised by a healthcare provider [see Warnings and Precautions (5.2, 5.3), Drug Interactions (7)].
• Educate patients and caregivers on how to recognize respiratory depression and emphasize the importance of calling 911 or getting emergency medical help right away in the event of a known or suspected overdose [see Warnings and Precautions (5.2)].
• Patient Access to an Opioid Overdose Reversal Agent for the Emergency Treatment of Opioid Overdose
  
  Inform patients and caregivers about opioid overdose reversal agents (e.g., naloxone, nalmefene) and discuss the importance of having access to an opioid overdose reversal agent. Because patients being treated for opioid use disorder are at risk for relapse, discuss the importance of having access to an opioid overdose reversal agent. Also discuss the importance of having access to an opioid overdose reversal agent if there are household members (including children) or other close contacts at risk for accidental ingestion or opioid overdose.
  
  Discuss with the patient the options for obtaining an opioid overdose reversal agent (e.g., prescription, over-the-counter (some products), or as part of a community-based program) [see Dosage and Administration (2.2), Warnings and Precautions (5.2)].
  
  There are important differences among the opioid overdose reversal agents. Be familiar with these differences, as outlined in the approved labeling for those products, prior to recommending or prescribing such an agent.
  
  Educate patients and caregivers on how to recognize the signs and symptoms of an opioid overdose.
  
  Explain to patients and caregivers that effects of opioid overdose reversal agents like naloxone and nalmefene are temporary, and that they must call 911 or get emergency medical help right away in all cases of known or suspected opioid overdose, even if an opioid overdose reversal agent is administered. Repeat administration may be necessary, particularly for overdose involving buprenorphine [see Dosage and Administration (2.2), Warnings and Precautions (5.2), Overdosage (10)].
  
  Advise patients and caregivers:
  • how to treat with an opioid overdose reversal agent in the event of an opioid overdose.
  • to tell family and friends about their opioid overdose reversal agent, and to keep it in a place where family and friends can easily access it in an emergency.
  • to read the Patient Information (or other educational material) that will come with their opioid overdose reversal agent. Emphasize the importance of doing this before an opioid emergency happens, so the patient and caregiver will know what to do.
• Advise patients that SUBOXONE sublingual film contains an opioid that can be a target for people who abuse prescription medications or street drugs. Caution patients to keep their films in a safe place, and to protect them from theft.
• Instruct patients to keep SUBOXONE sublingual film in a secure place, out of the sight and reach of children. Accidental or deliberate ingestion by a child may cause respiratory depression that can result in death. Advise patients to seek medical attention immediately if a child is exposed to SUBOXONE sublingual film.
• Inform patients that opioids could cause a rare but potentially life-threatening condition resulting from concomitant administration of serotonergic drugs. Warn patients of the symptoms of serotonin syndrome and to seek medical attention right away if symptoms develop. Instruct patients to inform their healthcare providers if they are taking, or plan to take serotonergic medications [see Drug Interactions (7)].
• Inform patients that opioids could cause adrenal insufficiency, a potentially life- threatening condition. Adrenal insufficiency may present with non-specific symptoms and signs such as nausea, vomiting, anorexia, fatigue, weakness, dizziness, and low blood pressure. Advise patients to seek medical attention if they experience a constellation of these symptoms [see Warnings and Precautions (5.6)].
• Advise patients to never give SUBOXONE sublingual film to anyone else, even if he or she has the same signs and symptoms. It may cause harm or death.
• Advise patients that selling or giving away this medication is against the law.
• Advise patients that, after SUBOXONE has completely dissolved in the oral mucosa, to take a sip of water, swish it gently around their teeth and gums, and swallow. Advise patients to wait for at least one hour after taking SUBOXONE before brushing teeth [see Warnings and Precautions (5.13)].
• Refer patients to dental care services and encourage them to have regular dental checkups while taking SUBOXONE. Instruct patients to inform their dentist that they have started therapy on SUBOXONE [see Warnings and Precautions (5.13)].
• Caution patients that SUBOXONE sublingual film may impair the mental or physical abilities required for the performance of potentially dangerous tasks such as driving or operating machinery. Caution should be taken especially during drug induction and dose adjustment and until individuals are reasonably certain that buprenorphine therapy does not adversely affect their ability to engage in such activities [see Warnings and Precautions (5.15)].
• Advise patients not to change the dosage of SUBOXONE sublingual film without consulting their healthcare provider.
• Advise patients to take SUBOXONE sublingual film once a day.
• Advise patients that if they miss a dose of SUBOXONE sublingual film they should take it as soon as they remember. If it is almost time for the next dose, they should skip the missed dose and take the next dose at the regular time.
• Inform patients that SUBOXONE sublingual film can cause drug dependence and that withdrawal signs and symptoms may occur when the medication is discontinued.
• Advise patients seeking to discontinue treatment with buprenorphine for opioid dependence to work closely with their healthcare provider on a tapering schedule and inform them of the potential to relapse to illicit drug use associated with discontinuation of opioid agonist/partial agonist medication-assisted treatment.
• Advise patients that, like other opioids, SUBOXONE sublingual film may produce orthostatic hypotension in ambulatory individuals [see Warnings and Precautions (5.16)].
• Advise patients to inform their healthcare provider if any other prescription medications, over-the-counter medications, or herbal preparations are prescribed or currently being used [see Drug Interactions (7)].
• Advise women that if they are pregnant while being treated with SUBOXONE sublingual film, the baby may have signs of withdrawal at birth and that withdrawal is treatable [see Warnings and Precautions (5.5), Use in Specific Populations (8.1)].
• Advise women who are breastfeeding to monitor the infant for drowsiness and difficulty breathing [see Use in Specific Populations (8.2)].
• Inform patients that chronic use of opioids may cause reduced fertility. It is not known whether these effects on fertility are reversible [see Use in Specific Populations (8.3)].
• Advise patients to inform their family members that, in the event of emergency, the treating healthcare provider or emergency room staff should be informed that the patient is physically dependent on an opioid and that the patient is being treated with SUBOXONE sublingual film.

Buprenorphine, like morphine and other opioids, has the potential for being abused and is subject to criminal diversion. This should be considered when prescribing or dispensing buprenorphine in situations when the clinician is concerned about an increased risk of misuse, abuse, or diversion. Healthcare professionals should contact their state professional licensing board or state controlled substances authority for information on how to prevent and detect abuse or diversion of this product.

Patients who continue to misuse, abuse, or divert buprenorphine products or other opioids should be provided with or referred for more intensive and structured treatment.

Abuse of buprenorphine poses a risk of overdose and death. This risk is increased with the abuse of buprenorphine and alcohol and other substances, especially benzodiazepines.

The healthcare provider may be able to more easily detect misuse or diversion by maintaining records of medication prescribed including date, dose, quantity, frequency of refills, and renewal requests of medication prescribed.

Proper assessment of the patient, proper prescribing practices, periodic re-evaluation of therapy, and proper handling and storage of the medication are appropriate measures that help to limit abuse of opioid drugs.

Prior to induction, consideration should be given to the type of opioid dependence (i.e., long‐ or short‐acting opioid products), the time since last opioid use, and the degree or level of opioid dependence.

Patients dependent on heroin or other short‐acting opioid products

Patients dependent on heroin or other short‐acting opioid products may be inducted with either SUBOXONE sublingual film or with sublingual buprenorphine monotherapy. At treatment initiation, the first dose of SUBOXONE sublingual film should be administered when objective signs of moderate opioid withdrawal appear, not less than six hours after the patient last used opioids.

It is recommended that an adequate treatment dose, titrated to clinical effectiveness, be achieved as rapidly as possible. In some studies, a too‐gradual induction over several days led to a high rate of drop‐out of buprenorphine patients during the induction period.

On Day 1, an induction dosage of up to 8 mg/2 mg SUBOXONE sublingual film is recommended. Clinicians should start with an initial dose of 2 mg/0.5 mg or 4 mg/1 mg buprenorphine/naloxone and may titrate upwards in 2 or 4 mg increments of buprenorphine, at approximately 2‐hour intervals, under supervision, to 8 mg/2 mg buprenorphine/naloxone based on the control of acute withdrawal symptoms.

On Day 2, a single daily dose of up to 16 mg/4 mg SUBOXONE sublingual film is recommended.

Because the exposure to naloxone is somewhat higher after buccal than after sublingual administration, it is recommended that the sublingual site of administration be used during induction to minimize exposure to naloxone, to reduce the risk of precipitated withdrawal.

Patients dependent on methadone or long‐acting opioid products

Patients dependent upon methadone or long‐acting opioid products may be more susceptible to precipitated and prolonged withdrawal during induction than those on short‐acting opioid products.

Buprenorphine/naloxone combination products have not been evaluated in adequate and well‐controlled studies for induction in patients who are physically dependent on long‐acting opioid products, and the naloxone in these combination products is absorbed in small amounts by the sublingual route and could cause worse precipitated and prolonged withdrawal. For this reason, buprenorphine monotherapy is recommended in patients taking long‐acting opioids when used according to approved administration instructions. Following induction, the patient may then be transitioned to once‐daily SUBOXONE sublingual film.

SUBOXONE® (buprenorphine and naloxone) sublingual film is an orange film, imprinted with a logo identifying the product and strength in white ink. It contains buprenorphine HCl, a mu-opioid receptor partial agonist, and a kappa-opioid receptor antagonist, and naloxone HCl dihydrate, an opioid antagonist, at a ratio of 4:1 (ratio of free bases). It is intended for sublingual or buccal administration and is available in four dosage strengths, 2 mg buprenorphine with 0.5 mg naloxone, 4 mg buprenorphine with 1 mg naloxone, 8 mg buprenorphine with 2 mg naloxone and 12 mg buprenorphine with 3 mg naloxone. Each film also contains polyethylene oxide, hydroxypropyl methylcellulose, maltitol, acesulfame potassium, lime flavor, citric acid, sodium citrate, FD&C yellow #6, and white ink.

Chemically, buprenorphine HCl is (2S)-2-[17-Cyclopropylmethyl-4,5α-epoxy-3-hydroxy-6-methoxy-6α,14- ethano-14α-morphinan-7α-yl]-3,3-dimethylbutan-2-ol hydrochloride. It has the following chemical structure:

Buprenorphine HCl has the molecular formula C₂₉H₄₁NO₄• HCl and the molecular weight is 504.10. It is a white or off-white crystalline powder, sparingly soluble in water, freely soluble in methanol, soluble in alcohol, and practically insoluble in cyclohexane.

Chemically, naloxone HCl dihydrate is 17-Allyl-4,5 α -epoxy-3, 14-dihydroxymorphinan-6-one hydrochloride dihydrate. It has the following chemical structure:

Naloxone hydrochloride dihydrate has the molecular formula C₁₉H₂₁NO₄• HCl • 2H₂O and the molecular weight is 399.87. It is a white to slightly off-white powder and is freely soluble in water, soluble in alcohol, and practically insoluble in toluene and ether.

Buprenorphine is a partial agonist at the mu-opioid receptor and chronic administration produces physical dependence of the opioid type, characterized by moderate withdrawal signs and symptoms upon abrupt discontinuation or rapid taper. The withdrawal syndrome is typically milder than seen with full agonists and may be delayed in onset [see Warnings and Precautions (5.7)].

Neonatal opioid withdrawal syndrome (NOWS) is an expected and treatable outcome of prolonged use of opioids during pregnancy [see Warnings and Precautions (5.5)].

• For maintenance, SUBOXONE sublingual film may be administered buccally or sublingually.
• The dosage of SUBOXONE sublingual film from Day 3 onwards should be progressively adjusted in increments/decrements of 2 mg/0.5 mg or 4 mg/1 mg buprenorphine/naloxone to a level that holds the patient in treatment and suppresses opioid withdrawal signs and symptoms.
• After treatment induction to the recommended dose of 16 mg/4 mg buprenorphine/naloxone per day, dosing should be further adjusted based on the individual patient and clinical response. The maintenance dose of SUBOXONE sublingual film is generally in the range of 4 mg/1 mg buprenorphine/naloxone to 24 mg/6 mg buprenorphine/naloxone per day. Dosages higher than 24 mg/6 mg daily have not been investigated in randomized clinical trials but may be appropriate for some patients.
• When determining the prescription quantity for unsupervised administration, consider the patient's level of stability, the security of his or her home situation, and other factors likely to affect the ability to manage supplies of take‐home medication.
• There is no maximum recommended duration of maintenance treatment. Patients may require treatment indefinitely and should continue for as long as patients are benefiting and the use of SUBOXONE sublingual film contributes to the intended treatment goals.

The safety and effectiveness of SUBOXONE sublingual film have not been established in pediatric patients. This product is not appropriate for the treatment of neonatal abstinence syndrome in neonates, because it contains naloxone, an opioid antagonist.

Clinical studies of SUBOXONE sublingual film, SUBOXONE sublingual tablets, or SUBUTEX sublingual tablets did not include sufficient numbers of subjects aged 65 and over to determine whether they responded differently than younger subjects. Other reported clinical experience has not identified differences in responses between the elderly and younger patients. Due to possible decreased hepatic, renal, or cardiac function and of concomitant disease or other drug therapy in geriatric patients, the decision to prescribe SUBOXONE sublingual film should be made cautiously in individuals 65 years of age or older and these patients should be monitored for signs and symptoms of toxicity or overdose.

SUBOXONE sublingual film is contraindicated in patients with a history of hypersensitivity to buprenorphine or naloxone as serious adverse reactions, including anaphylactic shock, have been reported [see Warnings and Precautions (5.9)].

The following serious adverse reactions are described elsewhere in the labeling:

• Addiction, Abuse, and Misuse [see Warnings and Precautions (5.1)]
• Respiratory and CNS Depression [see Warnings and Precautions (5.2), (5.3)]
• Neonatal Opioid Withdrawal Syndrome [see Warnings and Precautions (5.5)]
• Adrenal Insufficiency [see Warnings and Precautions (5.6)]
• Opioid Withdrawal [see Warnings and Precautions (5.7, 5.10)]
• Hepatitis, Hepatic Events [see Warnings and Precautions (5.8)]
• Hypersensitivity Reactions [see Warnings and Precautions (5.9)]
• Orthostatic Hypotension [see Warnings and Precautions (5.16)]
• Elevation of Cerebrospinal Fluid Pressure [see Warnings and Precautions (5.17)]
• Elevation of Intracholedochal Pressure [see Warnings and Precautions (5.18)]

Table 4 includes clinically significant drug interactions with SUBOXONE.

No differences in buprenorphine pharmacokinetics were observed between 9 dialysis-dependent and 6 normal patients following IV administration of 0.3 mg buprenorphine. The effects of renal failure on naloxone pharmacokinetics are unknown.

Because of the risks associated with accidental ingestion, misuse, and abuse, advise patients to store SUBOXONE sublingual film securely, out of sight and reach of children, and in a location not accessible by others, including visitors to the home [see Warnings and Precautions (5.1, 5.4), Drug Abuse and Dependence (9.2)]. Inform patients that leaving SUBOXONE sublingual film unsecured can pose a deadly risk to others in the home.

Advise patients and caregivers that when medicines are no longer needed, they should be disposed of promptly. Expired, unwanted, or unused SUBOXONE sublingual film should be disposed of by removing the SUBOXONE sublingual film from the foil packaging, and flushing the unused medication down the toilet (if a drug take-back option is not readily available). Inform patients that they can visit www.fda.gov/drugdisposal for a complete list of medicines recommended for disposal by flushing, as well as additional information on disposal of unused medicines.

Healthcare providers will need to decide when they cannot appropriately provide further management for particular patients. For example, some patients may be abusing or dependent on various drugs, or unresponsive to psychosocial intervention such that the healthcare provider does not feel that he/she has the expertise to manage the patient. In such cases, the healthcare provider may want to assess whether to refer the patient to a specialist or more intensive behavioral treatment environment. Decisions should be based on a treatment plan established and agreed upon with the patient at the beginning of treatment.

Patients who continue to misuse, abuse, or divert buprenorphine products or other opioids should be provided with, or referred to, more intensive and structured treatment.

Thorough QT studies with buprenorphine products have demonstrated QT prolongation ≤ 15 msec. This QTc prolongation effect does not appear to be mediated by hERG channels. Based on these two findings, buprenorphine is unlikely to be pro-arrhythmic when used alone in patients without risk factors. The risk of combining buprenorphine with other QT-prolonging agents is not known.

Consider these observations in clinical decisions when prescribing SUBOXONE sublingual film to patients with risk factors such as hypokalemia, bradycardia, recent conversion from atrial fibrillation, congestive heart failure, digitalis therapy, baseline QT prolongation, subclinical long-QT syndrome, or severe hypomagnesemia.

The effect of hepatic impairment on the pharmacokinetics of buprenorphine and naloxone has been evaluated in a pharmacokinetic study. Both drugs are extensively metabolized in the liver. While no clinically significant changes have been observed in subjects with mild hepatic impairment; the plasma levels have been shown to be higher and half-life values have been shown to be longer for both buprenorphine and naloxone in subjects with moderate and severe hepatic impairment. The magnitude of the effects on naloxone are greater than that on buprenorphine in both moderately and severely impaired subjects. The difference in magnitude of the effects on naloxone and buprenorphine are greater in subjects with severe hepatic impairment than in subjects with moderate hepatic impairment, and therefore the clinical impact of these effects is likely to be greater in patients with severe hepatic impairment than in patients with moderate hepatic impairment.

Buprenorphine/naloxone products should be avoided in patients with severe hepatic impairment and may not be appropriate for patients with moderate hepatic impairment [see Warnings and Precautions (5.12), Clinical Pharmacology (12.3)].

SUBOXONE sublingual film is indicated for treatment of opioid dependence. SUBOXONE sublingual film should be used as part of a complete treatment plan that includes counseling and psychosocial support.

SUBOXONE sublingual film contains buprenorphine and naloxone. Buprenorphine is a partial agonist at the mu-opioid receptor and an antagonist at the kappa-opioid receptor. Naloxone is a potent antagonist at mu opioid receptors and produces opioid withdrawal signs and symptoms in individuals physically dependent on full opioid agonists when administered parenterally.

Treatment should be initiated with supervised administration, progressing to unsupervised administration as the patient's clinical stability permits. SUBOXONE sublingual film is subject to diversion and abuse. When determining the prescription quantity for unsupervised administration, consider the patient's level of stability, the security of his or her home situation, and other factors likely to affect the ability to manage supplies of take‐home medication.

Ideally patients should be seen at reasonable intervals (e.g., at least weekly during the first month of treatment) based upon the individual circumstances of the patient. Medication should be prescribed in consideration of the frequency of visits. Provision of multiple refills is not advised early in treatment or without appropriate patient follow‐up visits. Periodic assessment is necessary to determine compliance with the dosing regimen, effectiveness of the treatment plan, and overall patient progress.

Once a stable dosage has been achieved and patient assessment (e.g., urine drug screening) does not indicate illicit drug use, less frequent follow‐up visits may be appropriate. A once‐monthly visit schedule may be reasonable for patients on a stable dosage of medication who are making progress toward their treatment objectives. Continuation or modification of pharmacotherapy should be based on the healthcare provider's evaluation of treatment outcomes and objectives such as:

• Absence of medication toxicity.
• Absence of medical or behavioral adverse effects.
• Responsible handling of medications by the patient.
• Patient's compliance with all elements of the treatment plan (including recovery‐oriented activities, psychotherapy, and/or other psychosocial modalities).
• Abstinence from illicit drug use (including problematic alcohol and/or benzodiazepine use).

If treatment goals are not being achieved, the healthcare provider should re‐evaluate the appropriateness of continuing the current treatment.

SUBOXONE sublingual film contains buprenorphine, a Schedule III controlled substance under the Controlled Substances Act.

Cases of adrenal insufficiency have been reported with opioid use, more often following greater than one month of use. Presentation of adrenal insufficiency may include non‐specific symptoms and signs including nausea, vomiting, anorexia, fatigue, weakness, dizziness, and low blood pressure. If adrenal insufficiency is suspected, confirm the diagnosis with diagnostic testing as soon as possible. If adrenal insufficiency is diagnosed, treat with physiologic replacement doses of corticosteroids. Wean the patient off of the opioid to allow adrenal function to recover and continue corticosteroid treatment until adrenal function recovers. Other opioids may be tried as some cases reported use of a different opioid without recurrence of adrenal insufficiency. The information available does not identify any particular opioids as being more likely to be associated with adrenal insufficiency.

• Addiction, Abuse, and Misuse: Buprenorphine can be abused in a similar manner to other opioids. Monitor patients for conditions indicative of diversion or progression of opioid dependence and addictive behaviors. Multiple refills should not be prescribed early in treatment or without appropriate patient follow-up visits. (5.1)
• Respiratory Depression: Life-threatening respiratory depression and death have occurred in association with buprenorphine use. Warn patients of the potential danger of self-administration of benzodiazepines or other CNS depressants while under treatment with SUBOXONE sublingual film. (5.2, 5.3)
• Unintentional Pediatric Exposure: Store SUBOXONE sublingual film safely out of the sight and reach of children. Buprenorphine can cause severe, possibly fatal, respiratory depression in children. (5.4)
• Neonatal Opioid Withdrawal Syndrome: Neonatal opioid withdrawal syndrome (NOWS) is an expected and treatable outcome of prolonged use of opioids during pregnancy (5.5)
• Adrenal Insufficiency: If diagnosed, treat with physiologic replacement of corticosteroids, and wean patient off of the opioid. (5.6)
• Risk of Opioid Withdrawal with Abrupt Discontinuation: If treatment is temporarily interrupted or discontinued, monitor patients for withdrawal and treat appropriately. (5.7)
• Risk of Hepatitis, Hepatic Events: Monitor liver function tests prior to initiation and during treatment and evaluate suspected hepatic events. (5.8)
• Precipitation of Opioid Withdrawal Signs and Symptoms: An opioid withdrawal syndrome is likely to occur with parenteral misuse of SUBOXONE sublingual film by individuals physically dependent on full opioid agonists, or by sublingual or buccal administration before the agonist effects of other opioids have subsided. (5.10)
• Risk of Overdose in Opioid‐Naïve Patients: SUBOXONE sublingual film is not appropriate as an analgesic. There have been reported deaths of opioid naïve individuals who received a 2 mg sublingual dose. (5.11)

Cases of dental caries, some severe (i.e., tooth fracture, tooth loss), have been reported following the use of transmucosal buprenorphine-containing products. Reported events include cavities, tooth decay, dental abscesses/infection, rampant caries, tooth erosion, fillings falling out, and, in some cases, total tooth loss. Treatment for these events included tooth extraction, root canal, dental surgery, as well as other restorative procedures (i.e., fillings, crowns, implants, dentures). Multiple cases were reported in individuals without any prior history of dental problems.

Refer patients to dental care services and encourage them to have regular dental checkups while taking SUBOXONE. Educate patients to seek dental care and strategies to maintain or improve oral health while being treated with transmucosal buprenorphine-containing products. Strategies include, but are not limited to, gently rinsing the teeth and gums with water and then swallowing after SUBOXONE has been completely dissolved in the oral mucosa. Advise patients to wait for at least one hour after taking SUBOXONE before brushing teeth [see Dosing and Administration (2.5), Information for Patients (17), Medication Guide].

• Administer SUBOXONE sublingual film as a single daily dose. (2.1)
• Strongly consider recommending or prescribing an opioid overdose reversal agent (e.g., naloxone, nalmefene) at the time SUBOXONE sublingual film is initiated or renewed because patients being treated for opioid use disorder have the potential for relapse, putting them at risk for opioid overdose. (2.2)
• To avoid precipitating withdrawal, induction with SUBOXONE sublingual film should be undertaken when objective and clear signs of withdrawal are evident and SUBOXONE sublingual film should be administered in divided doses when used as initial treatment. (2.3)
• For patients dependent on short‐acting opioid products who are in opioid withdrawal; on Day 1, administer up to 8 mg/2 mg SUBOXONE sublingual film (in divided doses). On Day 2, administer up to 16 mg/4 mg of SUBOXONE sublingual film as a single dose. (2.3)
• For patients dependent on methadone or long‐acting opioid products, induction onto sublingual buprenorphine monotherapy is recommended on Days 1 and 2 of treatment. (2.3)
• The maintenance dose of SUBOXONE sublingual film is generally in the range of 4 mg/1 mg to 24 mg/6 mg per day and should be based on clinical response. (2.4)
• Sublingual Administration: Place one film under the tongue, close to the base on the left or right side, and allow to completely dissolve. Buccal Administration: Place one film on the inside of the left or right cheek and allow to completely dissolve. (2.5)
• SUBOXONE sublingual film must be administered whole. Do not cut, chew, or swallow SUBOXONE sublingual film (2.5)
• When discontinuing treatment, gradually taper to avoid signs and symptoms of withdrawal. (2.8)

The decision to discontinue therapy with SUBOXONE sublingual film after a period of maintenance should be made as part of a comprehensive treatment plan. Advise patients of the potential to relapse to illicit drug use following discontinuation of opioid agonist/partial agonist medication‐assisted treatment. Taper patients to reduce the occurrence of opioid withdrawal signs and symptoms [See Warnings and Precautions (5.7)].

SUBOXONE sublingual film must be administered whole. Do not cut, chew, or swallow SUBOXONE sublingual film. Advise patients not to eat or drink anything until the film is completely dissolved.

SUBOXONE sublingual film is supplied as an orange rectangular film with a white printed logo in four dosage strengths:

• Buprenorphine 2 mg/naloxone 0.5 mg,
• Buprenorphine 4 mg/naloxone 1 mg,
• Buprenorphine 8 mg/naloxone 2 mg and
• Buprenorphine 12 mg/naloxone 3 mg

Like other opioids, SUBOXONE sublingual film may produce orthostatic hypotension in ambulatory patients.

The following adverse reactions have been identified during post-approval use of SUBOXONE sublingual film. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure.

The most frequently reported postmarketing adverse events were peripheral edema, stomatitis, glossitis, and blistering and ulceration of the mouth or tongue.

Serotonin syndrome: Cases of serotonin syndrome, a potentially life-threatening condition, have been reported during concomitant use of opioids with serotonergic drugs.

Adrenal insufficiency: Cases of adrenal insufficiency have been reported with opioid use, more often following greater than one month of use.

Anaphylaxis: Anaphylaxis has been reported with ingredients contained in SUBOXONE sublingual film.

Androgen deficiency: Cases of androgen deficiency have occurred with chronic use of opioids [see Clinical Pharmacology (12.2)].

Local reactions: Dental decay (including caries, tooth fracture, and tooth loss), glossodynia, glossitis, oral mucosal erythema, oral hypoesthesia, and stomatitis

Hypoglycemia: Cases of hypoglycemia have been reported in patients taking opioids. Most reports were in patients with at least one predisposing risk factor (e.g., diabetes).

Opioid-induced esophageal dysfunction (OIED): Cases of OIED have been reported in patients taking opioids and may occur more frequently in patients taking higher doses of opioids, and/or in patients taking opioids longer term.

• Lactation: Buprenorphine passes into mother's milk. (8.2)
• Geriatric Patients: Monitor for sedation and respiratory depression. (8.5)
• Moderate or Severe Hepatic Impairment: Buprenorphine/naloxone products are not recommended in patients with severe hepatic impairment and may not be appropriate for patients with moderate hepatic impairment. (8.6)

Cases of hypersensitivity to buprenorphine and naloxone containing products have been reported both in clinical trials and in the post‐marketing experience. Cases of bronchospasm, angioneurotic edema, and anaphylactic shock have been reported. The most common signs and symptoms include rashes, hives, and pruritus. A history of hypersensitivity to buprenorphine or naloxone is a contraindication to the use of SUBOXONE sublingual film.

Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice.

The safety of SUBOXONE sublingual film is supported by clinical trials using SUBUTEX® (buprenorphine) sublingual tablets and SUBOXONE (buprenorphine and naloxone) sublingual tablets, and other trials using buprenorphine sublingual solutions, as well as an open-label study in 194 patients treated with SUBOXONE sublingual film administered sublingually and 188 patients treated with the film administered buccally. In total, safety data from clinical studies are available from over 3000 opioid-dependent subjects exposed to buprenorphine at doses in the range used in the treatment of opioid dependence. Few differences in the adverse event profile were noted with regard to sublingually and bucally administered SUBOXONE sublingual film, SUBOXONE sublingual tablets, SUBUTEX sublingual tablets and a buprenorphine ethanolic sublingual solution.

The most common adverse event (> 1%) associated with the sublingual administration of the SUBOXONE sublingual film was oral hypoesthesia. Other adverse events were constipation, glossodynia, oral mucosal erythema, vomiting, intoxication, disturbance in attention, palpitations, insomnia, withdrawal syndrome, hyperhidrosis, and blurred vision.

The most common adverse events associated with the buccal administration were similar to those observed with sublingual administration of the film.

Other adverse event data were derived from larger, controlled studies of SUBOXONE sublingual tablets and SUBUTEX sublingual tablets and of buprenorphine sublingual solution. In a comparative study of SUBOXONE sublingual tablets and SUBUTEX sublingual tablets, adverse event profiles were similar for subjects treated with 16 mg/4 mg SUBOXONE sublingual tablets or 16 mg SUBUTEX sublingual tablets. The following adverse events were reported to occur by at least 5% of patients in a 4 week study of SUBOXONE sublingual tablets and SUBUTEX sublingual tablets.

The adverse event profile of buprenorphine was also characterized in the dose-controlled study of a buprenorphine ethanolic solution, over a range of doses in four months of treatment. Table 3 shows adverse events reported by at least 5% of subjects in any dose group in the dose-controlled trial.

The safety of SUBOXONE sublingual film during treatment induction is supported by a clinical trial using 16 patients treated with SUBOXONE sublingual film and 18 treated with a buprenorphine-only sublingual film. Few differences in the adverse event profiles were noted between SUBOXONE sublingual film and the buprenorphine-only sublingual film.

The most common adverse event occurring during treatment induction and the 3 days following induction using SUBOXONE sublingual film was restlessness. Other adverse events were anxiety, piloerection, stomach discomfort, irritability, headache, rhinorrhea, cold sweat, arthralgia, and lacrimation increased.

Four subjects left the study early on the first day of sublingual film administration. However, there was no evidence to suggest that any of the four subjects experienced precipitated withdrawal secondary to the administration of buprenorphine or buprenorphine/naloxone sublingual films.

SUBOXONE sublingual film contains buprenorphine, a schedule III controlled substance that can be abused in a manner similar to other opioids, legal or illicit. Prescribe and dispense buprenorphine with appropriate precautions to minimize risk of misuse, abuse, or diversion, and ensure appropriate protection from theft, including in the home. Clinical monitoring appropriate to the patient's level of stability is essential. Multiple refills should not be prescribed early in treatment or without appropriate patient follow‐up visits [see Drug Abuse and Dependence (9.2)].

Advise patients to read the FDA-approved patient labeling (Medication Guide).

Buprenorphine can cause severe, possibly fatal, respiratory depression in children who are accidentally exposed to it. Store buprenorphine‐containing medications safely out of the sight and reach of children and destroy any unused medication appropriately [see Patient Counseling Information (17)].

Cases of cytolytic hepatitis and hepatitis with jaundice have been observed in individuals receiving buprenorphine in clinical trials and through post‐marketing adverse event reports. The spectrum of abnormalities ranges from transient asymptomatic elevations in hepatic transaminases to case reports of death, hepatic failure, hepatic necrosis, hepatorenal syndrome, and hepatic encephalopathy. In many cases, the presence of pre‐existing liver enzyme abnormalities, infection with hepatitis B or hepatitis C virus, concomitant usage of other potentially hepatotoxic drugs, and ongoing injecting drug use may have played a causative or contributory role. In other cases, insufficient data were available to determine the etiology of the abnormality. Withdrawal of buprenorphine has resulted in amelioration of acute hepatitis in some cases; however, in other cases no dose reduction was necessary. The possibility exists that buprenorphine had a causative or contributory role in the development of the hepatic abnormality in some cases. Liver function tests, prior to initiation of treatment, are recommended to establish a baseline. Periodic monitoring of liver function during treatment is also recommended. A biological and etiological evaluation is recommended when a hepatic event is suspected. Depending on the case, SUBOXONE sublingual film may need to be carefully discontinued to prevent withdrawal signs and symptoms and a return by the patient to illicit drug use, and strict monitoring of the patient should be initiated.

SUBOXONE sublingual film is supplied as an orange rectangular film with a white printed logo in child-resistant polyester/foil laminated pouches:

• NDC 12496-1202-3 (buprenorphine 2 mg/naloxone 0.5 mg/film; content expressed in terms of free base, equivalent to 2.16 mg buprenorphine hydrochloride USP and 0.61 mg naloxone hydrochloride dihydrate USP) - 30 films per carton
• NDC 12496-1204-3 (buprenorphine 4 mg/naloxone 1 mg/film; content expressed in terms of free base, equivalent to 4.32 mg buprenorphine hydrochloride USP and 1.22 mg naloxone hydrochloride dihydrate USP) - 30 films per carton
• NDC 12496-1208-3 (buprenorphine 8 mg/naloxone 2 mg/film; content expressed in terms of free base, equivalent to 8.64 mg buprenorphine hydrochloride USP and 2.44 mg naloxone hydrochloride dihydrate USP) - 30 films per carton
• NDC 12496-1212-3 (buprenorphine 12 mg/naloxone 3 mg/film; content expressed in terms of free base, equivalent to 12.96 mg buprenorphine hydrochloride USP and 3.66 mg naloxone hydrochloride dihydrate USP) - 30 films per carton

Store at 25°C (77°F), excursions permitted to 15-30°C (59-86°F) [see USP Controlled Room Temperature].

Store SUBOXONE sublingual film securely and dispose of properly [see Patient Counseling Information (17)].

Neonatal opioid withdrawal syndrome (NOWS) is an expected and treatable outcome of prolonged use of opioids during pregnancy, whether that use is medically‐authorized or illicit. Unlike opioid withdrawal syndrome in adults, NOWS may be life‐threatening if not recognized and treated in the neonate. Healthcare professionals should observe newborns for signs of NOWS and manage accordingly [see Use in Specific Populations (8.1)].

Advise pregnant women receiving opioid addiction treatment with SUBOXONE sublingual film of the risk of neonatal opioid withdrawal syndrome and ensure that appropriate treatment will be available [see Use in Specific Populations (8.1)]. This risk must be balanced against the risk of untreated opioid addiction which often results in continued or relapsing illicit opioid use and is associated with poor pregnancy outcomes. Therefore, prescribers should discuss the importance and benefits of management of opioid addiction throughout pregnancy.

As with other opioids, buprenorphine may obscure the diagnosis or clinical course of patients with acute abdominal conditions.

Buprenorphine has been shown to increase intracholedochal pressure, as do other opioids, and thus should be administered with caution to patients with dysfunction of the biliary tract.

Buprenorphine, like other opioids, may elevate cerebrospinal fluid pressure and should be used with caution in patients with head injury, intracranial lesions, and other circumstances when cerebrospinal pressure may be increased. Buprenorphine can produce miosis and changes in the level of consciousness that may interfere with patient evaluation.

There have been reported deaths of opioid ‐naïve individuals who received a 2 mg dose of buprenorphine as a sublingual tablet for analgesia. SUBOXONE sublingual film is not appropriate as an analgesic.

SUBOXONE sublingual film is administered sublingually or buccally as a single daily dose.

Medication should be prescribed in consideration of the frequency of visits. Provision of multiple refills is not advised early in treatment or without appropriate patient follow‐up visits.

Buprenorphine/naloxone products are not recommended in patients with severe hepatic impairment and may not be appropriate for patients with moderate hepatic impairment. The doses of buprenorphine and naloxone in this fixed‐dose combination product cannot be individually titrated, and hepatic impairment results in a reduced clearance of naloxone to a much greater extent than buprenorphine. Therefore, patients with severe hepatic impairment will be exposed to substantially higher levels of naloxone than patients with normal hepatic function. This may result in an increased risk of precipitated withdrawal at the beginning of treatment (induction) and may interfere with buprenorphine's efficacy throughout treatment. In patients with moderate hepatic impairment, the differential reduction of naloxone clearance compared to buprenorphine clearance is not as great as in subjects with severe hepatic impairment. However, buprenorphine/naloxone products are not recommended for initiation of treatment (induction) in patients with moderate hepatic impairment due to the increased risk of precipitated withdrawal. Buprenorphine/naloxone products may be used with caution for maintenance treatment in patients with moderate hepatic impairment who have initiated treatment on a buprenorphine product without naloxone. However, patients should be carefully monitored and consideration given to the possibility of naloxone interfering with buprenorphine's efficacy [see Use in Specific Populations (8.6)].

SUBOXONE sublingual film may impair the mental or physical abilities required for the performance of potentially dangerous tasks such as driving a car or operating machinery, especially during treatment induction and dose adjustment. Caution patients about driving or operating hazardous machinery until they are reasonably certain that SUBOXONE sublingual film therapy does not adversely affect his or her ability to engage in such activities.

As indicated in Table 1, the sizes and the compositions of the four units of SUBOXONE sublingual films, i.e., 2 mg/0.5 mg, 4 mg/1 mg, 8 mg/2 mg and the 12 mg/3 mg units, are different from one another. If patients switch between various combinations of lower and higher strength units of SUBOXONE sublingual films to obtain the same total dose, (e.g., from three 4 mg/1 mg units to a single 12 mg/3 mg unit, or vice‐versa), systemic exposures of buprenorphine and naloxone may be different and patients should be monitored for over‐dosing or under‐dosing. For this reason, pharmacist should not substitute one or more film strengths for another without approval of the prescriber.

Buprenorphine is a partial agonist at the mu‐opioid receptor and chronic administration produces physical dependence of the opioid type, characterized by withdrawal signs and symptoms upon abrupt discontinuation or rapid taper. The withdrawal syndrome is typically milder than seen with full agonists and may be delayed in onset [see Drug Abuse and Dependence (9.3)]. When discontinuing SUBOXONE sublingual film, gradually taper the dosage [see Dosage and Administration (2.8)].

Because it contains naloxone, SUBOXONE sublingual film is likely to produce withdrawal signs and symptoms if misused parenterally by individuals dependent on full opioid agonists such as heroin, morphine, or methadone. Because of the partial agonist properties of buprenorphine, SUBOXONE sublingual film may precipitate opioid withdrawal signs and symptoms in such persons if administered before the agonist effects of the opioid have subsided.

The systemic exposure of buprenorphine between buccal and sublingual administration of SUBOXONE sublingual film is similar. Therefore, once induction is complete, patients can switch between buccal and sublingual administration without significant risk of under or overdosing.

Concomitant use of buprenorphine and benzodiazepines and/or other CNS depressants (e.g., alcohol, non-benzodiazepine sedative/hypnotics, anxiolytics, tranquilizers, muscle relaxants, general anesthetics, antipsychotics, gabapentinoids [gabapentin or pregabalin], and other opioids) increases the risk of adverse reactions including overdose, respiratory depression, and death. Medication-assisted treatment of opioid use disorder, however, should not be categorically denied to patients taking these drugs. Prohibiting or creating barriers to treatment can pose an even greater risk of morbidity and mortality due to the opioid use disorder alone.

As a routine part of orientation to buprenorphine treatment, educate patients about the risks of concomitant use of benzodiazepines, sedatives, opioid analgesics, and alcohol.

Develop strategies to manage use of prescribed or illicit benzodiazepines or other CNS depressants at initiation of buprenorphine treatment, or if it emerges as a concern during treatment. Adjustments to induction procedures and additional monitoring may be required. There is no evidence to support dose limitations or arbitrary caps of buprenorphine as a strategy to address benzodiazepine use in buprenorphine‐treated patients. However, if a patient is sedated at the time of buprenorphine dosing, delay or omit the buprenorphine dose if appropriate.

Cessation of benzodiazepines or other CNS depressants is preferred in most cases of concomitant use. In some cases, monitoring in a higher level of care for taper may be appropriate. In others, gradually tapering a patient off of a prescribed benzodiazepine or other CNS depressant or decreasing to the lowest effective dose may be appropriate.

For patients in buprenorphine treatment, benzodiazepines are not the treatment of choice for anxiety or insomnia. Before co‐prescribing benzodiazepines, ensure that patients are appropriately diagnosed and consider alternative medications and non‐pharmacologic treatments to address anxiety or insomnia. Ensure that other healthcare providers prescribing benzodiazepines or other CNS depressants are aware of the patient's buprenorphine treatment and coordinate care to minimize the risks associated with concomitant use.

If concomitant use is warranted, strongly consider recommending or prescribing an opioid overdose reversal agent, as is recommended for all patients on buprenorphine treatment for opioid use disorder [see Warnings and Precautions (5.2)].

In addition, take measures to confirm that patients are taking their medications as prescribed and are not diverting or supplementing with illicit drugs. Toxicology screening should test for prescribed and illicit benzodiazepines [see Drug Interactions (7)].

Buprenorphine has been associated with life‐threatening respiratory depression and death. Many, but not all, postmarketing reports regarding coma and death involved misuse by self‐injection or were associated with the concomitant use of buprenorphine and benzodiazepines or other CNS depressants, including alcohol. Warn patients of the potential danger of self‐administration of benzodiazepines or other CNS depressants while under treatment with SUBOXONE sublingual film [see Warnings and Precautions (5.3), Drug Interactions (7)].

Use SUBOXONE sublingual film with caution in patients with compromised respiratory function (e.g., chronic obstructive pulmonary disease, cor pulmonale, decreased respiratory reserve, hypoxia, hypercapnia, or pre-existing respiratory depression).

Educate patients and caregivers on how to recognize respiratory depression and emphasize the importance of calling 911 or getting emergency medical help right away in the event of a known or suspected overdose [see Patient Counseling Information (17)].

Opioids can cause sleep-related breathing disorders including central sleep apnea (CSA) and sleep-related hypoxemia. Opioid use increases the risk of CSA in a dose-dependent fashion. In patients who present with CSA, consider decreasing the opioid dosage using best practices for opioid taper [see Dosage and Administration (2.8)].

Patients being switched between buprenorphine and naloxone or buprenorphine only sublingual tablets and SUBOXONE sublingual film should be started on the same dosage of the previously administered product. However, dosage adjustments may be necessary when switching between buprenorphine products. Not all strengths and combinations of the SUBOXONE sublingual films are bioequivalent to SUBOXONE® sublingual tablets as observed in pharmacokinetic studies [see Clinical Pharmacology (12.3)]. Therefore, systemic exposures of buprenorphine and naloxone may be different when patients are switched from tablets to film or vice‐versa. Patients should be monitored for symptoms related to over‐dosing or under‐dosing.
