Do not administer more frequently than recommended. 2.5 Dosage Modifications in Patients with Renal Impairment or Hepatic Impairment Prior to initiating UZEDY in patients with renal or hepatic impairment, titrate with oral risperidone to at least 2 mg once daily. Following oral titration, and based on clinical response and tolerability, the recommended dosage of UZEDY is 50 mg once monthly [see Use in Specific Populations ( 8.6 , 8.7 ) and Clinical Pharmacology ( 12.3 )]. 2.6 Dosage Modifications for Concomitant Use with Strong CYP2D6 Inhibitors and Strong CYP3A4 Inducers Concomitant Use with Strong CYP2D6 Inhibitors When initiation of fluoxetine or paroxetine is considered, place patients on a lower dose of UZEDY prior to the planned start of fluoxetine or paroxetine therapy to adjust for the expected increase in plasma concentrations of risperidone. When fluoxetine or paroxetine is initiated in patients receiving the recommended dose of 50 mg once monthly or 100 mg once every 2 months of UZEDY, continue treatment with these doses unless clinical judgment necessitates interruption of UZEDY [see Drug Interactions ( 7.1 )] . Concomitant Use with Strong CYP3A4 Inducers At the initiation of therapy with strong CYP3A4 inducers (such as carbamazepine), patients should be closely monitored during the first 4 to 8 weeks since the dose of UZEDY may need to be adjusted. A dose increase, or additional oral risperidone, may be considered. On discontinuation of a strong CYP3A4 inducer, re-evaluated the dosage of UZEDY or any additional oral risperidone therapy and, if necessary, decrease to adjust for the expected increase in plasma concentration of risperidone. On discontinuation of a strong CYP3A4 inducer in a patient treated with UZEDY 50 mg once monthly or 100 mg once every 2 months, continue treatment with these doses unless clinical judgment necessitates interruption of UZEDY [see Drug Interactions ( 7.1 )] . 2.7 Preparation and Administration Instructions Read the instructions for preparation and administration below before administering UZEDY. For subcutaneous injection only. Do not inject by any other route. To be administered by a healthcare professional only. Allow UZEDY to come to room temperature for at least 30 minutes prior to administration. As a universal precaution, always wear gloves. STEP 1 Check to make sure UZEDY kit contains: One sterile single-dose, prefilled glass syringe One sterile 21G x 5/8” needle Do not substitute any components of the kit for administration. STEP 2 Remove the kit from refrigerated storage and allow the package to sit at room temperature (20°C to 25°C [68°F to 77°F]) for at least 30 minutes. Note: UZEDY is a solid at refrigerated temperatures and must reach room temperature prior to administration. Do not warm any other way and keep protected from light. STEP 3 Check that the drug in the syringe is white to off-white, opaque in color, and free from non-white particulate matter. Check that the pouch label states the needle size is 21G x 5/8”. Do not use if any component of the kit is damaged or if the expiration date has passed. STEP 4 Expose the safety needle hub by peeling back the paper tab of the needle pouch. Set aside for use in Step 7. STEP 5 IMPORTANT: This step must be performed to ensure complete dosing. UZEDY is viscous and forceful downward flicks are required to move the bubble to the cap of the syringe. Failure to move the bubble to the cap of the syringe could result in incomplete dosage. Firmly hold the syringe by the white collar. Flick Syringe Forcefully Three Times to Move the Bubble to the Cap Flick with a forceful downward whipping motion of your full arm to move the bubble to the cap of the syringe. Repeat this action 3 times to ensure that the bubble is at the cap of the syringe. Note: Standing while you do this may help achieve required force. Check that the Bubble is at the Cap of the Syringe The bubble will appear partially opaque. Holding the syringe up to light or against a dark backdrop may improve visibility. If the bubble is not at the cap, repeat Step 5 until it is. STEP 6 Hold the syringe vertically by the white collar. Bend and snap off the cap. Do not touch the syringe tip to avoid contamination. STEP 7 Attach the Needle to the Syringe Hold the syringe vertically with the white collar at the top. Push the green hub of safety needle inside the white collar of syringe and rotate the safety needle while holding the white collar until secure and tight. Inspect the needle connection to check that the hub is not damaged. STEP 8 Select Injection Site from the Following Areas: Stomach area (abdomen) around the belly button Back and outer area of the upper arms Do not inject UZEDY anywhere except in the areas specified above. Do not inject UZEDY into an area that is tender, red, bruised, callused, tattooed, hard, or has scars or stretch marks. STEP 9 Clean the Injection Site with an alcohol wipe. STEP 10 Remove the needle sheath by pulling the needle sheath away from the green hub to expose the needle. Do not expel any visible air bubble. STEP 11 Pinch at least 1 inch of the area of cleaned skin with your free hand. STEP 12 Insert the needle into subcutaneous tissue (actual angle of injection will depend on the amount of subcutaneous tissue). Do not apply pressure to the plunger. STEP 13 Release the pinched skin once the needle is in the subcutaneous tissue. STEP 14 Inject the Medication Push on the plunger using a slow, firm, and steady push until the entire dose is delivered. Inject the entire dose at one time, without interruption. Check that the plunger stopper is at the White Collar. IMPORTANT: UZEDY is viscous. Resistance will be experienced during dose delivery. Do not use excessive force in an attempt to deliver UZEDY faster. STEP 15 Wait 2-3 seconds after the entire dose is delivered before removing the needle. Slowly pull the needle out from the injection site at the same angle as insertion. STEP 16 Activate (lock) the safety needle shield using one of the following methods: Surface Activation: Place the needle shield on a flat surface and pull the syringe backward until the needle shield covers the needle tip. Finger/Thumb Activation: Press either your thumb or finger on the needle shield and push it forward until the needle shield covers the needle tip. There will be an audible click when the needle safety shield is locked. Dispose of all syringe components in a suitable sharps container. image image image image image image image image image image image image image image image image image image image image

Treatment of Schizophrenia in Adults UZEDY is to be administered subcutaneously [see Dosage and Administration ( 2.1 )]. The safety of UZEDY for the treatment of schizophrenia in adults is based on adequate and well-controlled studies of oral risperidone in studies of patients with schizophrenia and other indications. The results of those adequate and well-controlled studies are presented below. The data described in this section are derived from a clinical trial database consisting of 9,803 patients exposed to one or more doses of oral risperidone for the treatment of schizophrenia and other psychiatric disorders. Of these 9,803 patients, 2,687 were patients who received oral risperidone while participating in double-blind, placebo-controlled trials. The conditions and duration of treatment with oral risperidone varied greatly and included (in overlapping categories) double-blind, fixed- and flexible-dose, placebo- or active-controlled studies and open-label phases of studies, inpatients and outpatients, and short-term (up to 12 weeks) and longer-term (up to 3 years) exposures. Safety was assessed by collecting adverse reactions and performing physical examinations, vital signs, body weights, laboratory analyses, and ECGs. Injection site reactions for UZEDY presented in this section (see “Injection Site Reactions with UZEDY” below) are based on a randomized withdrawal study in patients with schizophrenia consisting of a 12-week open-label oral risperidone (2 mg to 5 mg) stabilization phase, followed by a placebo-controlled phase in which patients were randomized to UZEDY (once monthly or once every 2 months) or placebo for a variable time until impending relapse or study completion [see Clinical Studies ( 14 )] . The safety of UZEDY was evaluated in a total of 740 adult patients with schizophrenia who received at least 1 dose of UZEDY during the clinical development program. A total of 351 patients were exposed to UZEDY for at least 6 months, of which 221 patients were exposed to UZEDY for at least 12 months, which included 112 patients exposed to once monthly and 109 patients to once every 2 months dosing regimens. In addition, 32 patients were exposed to UZEDY for at least 24 months. Treatment of Bipolar Disorder in Adults UZEDY is to be administered subcutaneously [see Dosage and Administration ( 2.1 )] . The data presented below are from studies with another risperidone long-acting injection given once every 2 weeks that was administered intramuscularly. The safety of UZEDY as monotherapy or as adjunctive therapy to lithium or valproate for the maintenance treatment of Bipolar I Disorder in adults is based on adequate and well-controlled studies of another risperidone long-acting injection given once every 2 weeks. The results of those adequate and well-controlled studies are presented below. Safety data are presented from a trial assessing the efficacy and safety of another risperidone long-acting injection, given once every 2 weeks, when administered as monotherapy for maintenance treatment in patients with bipolar I disorder. Safety data are also presented from a trial assessing the efficacy and safety of another risperidone long-acting injection, given once every 2 weeks, administered as adjunctive maintenance treatment in patients with bipolar disorder. Adverse Reactions in Studies with Oral Risperidone The most common adverse reactions in clinical trials of oral risperidone (>5% and twice placebo) were parkinsonism, akathisia, dystonia, tremor, sedation, dizziness, anxiety, blurred vision, nausea, vomiting, upper abdominal pain, stomach discomfort, dyspepsia, diarrhea, salivary hypersecretion, constipation, dry mouth, increased appetite, increased weight, fatigue, rash, nasal congestion, upper respiratory tract infection, nasopharyngitis, and pharyngolaryngeal pain.

Discontinuations Due to Adverse Drug Reactions with Another Long-Acting Injection Risperidone, Given Once Every 2 Weeks Bipolar Disorder In a 24-month double-blind, placebo-controlled treatment period of the trial assessing the efficacy and safety of another risperidone long-acting injection, given once every 2 weeks, monotherapy for maintenance treatment in patients with bipolar I disorder, 1 (0.6%) of 154 patients treated with another risperidone long-acting injection, given once every 2 weeks, discontinued due to an adverse reaction (hyperglycemia). In the 52-week double-blind phase of the placebo-controlled trial in which patients treated with another risperidone long-acting injection, given once every 2 weeks, was administered as adjunctive therapy to patients with bipolar disorder in addition to continuing with their usual treatment, approximately 4% (3/72) of patients treated with another risperidone long-acting injection, given once every 2 weeks, discontinued treatment due to an adverse event, compared with 1.5% (1/67) of placebo-treated patients. Adverse reactions associated with discontinuation in patients treated with another risperidone long-acting injection, given once every 2 weeks, were hypokinesia (one patient) and tardive dyskinesia (one patient). Dose Dependency of Adverse Reactions in Clinical Trials of Oral Risperidone Extrapyramidal Symptoms Data from two fixed-dose trials in adults with schizophrenia provided evidence of dose-relatedness for extrapyramidal symptoms associated with oral risperidone treatment. Two methods were used to measure extrapyramidal symptoms (EPS) in an 8-week trial comparing 4 fixed doses of oral risperidone (2, 6, 10, and 16 mg/day), including (1) a Parkinsonism score (mean change from baseline) from the Extrapyramidal Symptom Rating Scale, and (2) incidence of spontaneous complaints of EPS: Table 11: Extrapyramidal Symptoms Associated with Oral Risperidone-Treated Adult Patients in an 8-Week Fixed Dose Schizophrenia Trial Dose Groups Placebo Oral Risperidone 2 mg Oral Risperidone 6 mg Oral Risperidone 10 mg Oral Risperidone 16 mg Parkinsonism 1.2 0.9 1.8 2.4 2.6 EPS Incidence 13% 17% 21% 21% 35% Similar methods were used to measure extrapyramidal symptoms (EPS) in an 8-week trial comparing 5 fixed doses of oral risperidone (1, 4, 8, 12, and 16 mg/day): Table 12: Extrapyramidal Symptoms Associated with Oral Risperidone-Treated Adult Patients in an 8-Week Fixed Dose Schizophrenia Trial Dose Groups Oral Risperidone 1 mg Oral Risperidone 4 mg Oral Risperidone 8 mg Oral Risperidone 12 mg Oral Risperidone 16 mg Parkinsonism 0.6 1.7 2.4 2.9 4.1 EPS Incidence 7% 12% 17% 18% 20% Changes in Body Weight Weight gain was observed in short-term, controlled trials and longer-term uncontrolled studies in adults [see Warnings and Precautions ( 5.5 ) and Adverse Reactions ( 6 )] . Dystonia Symptoms of dystonia, prolonged abnormal contractions of muscle groups, may occur in susceptible individuals during the first few days of treatment. Dystonic symptoms include: spasm of the neck muscles, sometimes progressing to tightness of the throat, swallowing difficulty, difficulty breathing, and/or protrusion of the tongue. While these symptoms can occur at low doses, they occur more frequently and with greater severity with high potency and at higher doses of first generation antipsychotic drugs. An elevated risk of acute dystonia is observed in males and younger age groups. Other Adverse Reactions Adverse reaction data elicited by a checklist for side effects from a large study comparing 5 fixed doses of oral risperidone (1, 4, 8, 12, and 16 mg/day) were explored for dose-relatedness of adverse events. A Cochran-Armitage Test for trend in these data revealed a positive trend (p<0.05) for the following adverse reactions: somnolence, vision abnormal, dizziness, palpitations, weight increase, erectile dysfunction, ejaculation disorder, sexual function abnormal, fatigue, and skin discoloration. Changes in ECG Between-group comparisons for pooled placebo-controlled trials of oral risperidone in adults revealed no statistically significant differences between oral risperidone and placebo in mean changes from baseline in ECG parameters, including QT, QTc, and PR intervals, and heart rate. When all oral risperidone doses were pooled from randomized controlled trials in several indications, there was a mean increase in heart rate of 1 beat per minute compared to no change for placebo patients. In short-term schizophrenia trials, higher doses of oral risperidone were associated with a higher mean increase in heart rate compared to placebo (4 to 6 beats per minute). The ECGs of 227 patients with Bipolar I Disorder were evaluated in the 24-month double-blind, placebo-controlled period. There were no clinically relevant differences in QTc intervals (using Fridericia's and linear correction factors) during treatment with another risperidone long-acting injection, given once every 2 weeks, compared to placebo. The ECGs of 85 patients with bipolar disorder were evaluated in the 52-week double-blind, placebo-controlled trial. There were no statistically significant differences in QTc intervals (using Fridericia's and linear correction factors) during adjunctive treatment with either another risperidone long-acting injection (25 mg, 37.5 mg, or 50 mg), given once every 2 weeks, or placebo in addition to treatment as usual. Injection Site Reactions with UZEDY Local tolerability assessments were administered to patients who reported injection site adverse reactions in a randomized withdrawal study with UZEDY in adult patients with schizophrenia. The injection site was assessed by appropriately trained personnel throughout the clinical development program. All injection site reactions (nodule, pruritus, erythema, mass, and swelling) were mild to moderate in severity with the exception of 1 case of severe pruritus which resolved after 6 days. Injection site reactions were reported in 22 patients (13%) in the placebo group, 36 patients (20%) in the UZEDY once monthly group, and 37 patients (21%) in the UZEDY once every 2 months group. The most common injection site reactions were: nodule (7% in each UZEDY-treated group and 3% in the placebo group) and pruritus (5% and 3% in the UZEDY-treated once monthly and once every 2 months groups, respectively, and 2% in the placebo group). 6.2 Postmarketing Experience The following adverse reactions have been identified during post-approval use of oral risperidone. 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. These adverse reactions include: alopecia, anaphylactic reaction, angioedema, atrial fibrillation, cardiopulmonary arrest, catatonia, diabetic ketoacidosis in patients with impaired glucose metabolism, dysgeusia, hypoglycemia, hypothermia, ileus, inappropriate antidiuretic hormone secretion, intestinal obstruction, jaundice, mania, pancreatitis, pituitary adenoma, precocious puberty, pulmonary embolism, QT prolongation, sleep apnea syndrome, somnambulism, Stevens-Johnson syndrome and toxic epidermal necrolysis (SJS/TEN), sudden death, thrombocytopenia, thrombotic thrombocytopenic purpura, urinary retention, and water intoxication. In addition, the following adverse reactions have been observed during postapproval use of UZEDY: injection site pain. In addition, the following adverse reactions have been observed during postapproval use of another risperidone long-acting injection, given intramuscularly once every 2 weeks: cerebrovascular disorders, including cerebrovascular accidents, and diabetes mellitus aggravated. Retinal artery occlusion after injection of another risperidone long-acting injection, given intramuscularly once every 2 weeks, has been reported during postmarketing surveillance. This has been reported in the presence of abnormal arteriovenous anastomosis. Serious injection site reactions including abscess, cellulitis, cyst, hematoma, necrosis, nodule, and ulcer have been reported with another risperidone long-acting injection, given intramuscularly once every 2 weeks, during postmarketing surveillance. Isolated cases required surgical intervention. Very rarely, cases of anaphylactic reaction after injection with another risperidone long-acting injection, given intramuscularly once every 2 weeks, have been reported during postmarketing experience in patients who have previously tolerated oral risperidone. Postmarketing cases of extrapyramidal symptoms (dystonia and dyskinesia) have been reported in patients concomitantly taking methylphenidate and risperidone when there was an increase or decrease in dosage, initiation, or discontinuation of either or both medications.

The interactions of UZEDY with co-administration of other drugs have not been studied. The drug interaction data provided in this section is based on studies with oral risperidone. Strong CYP2D6 inhibitors (e.g., fluoxetine, paroxetine): Increase risperidone plasma concentration. ( 2.6 , 7.1 ) Strong CYP3A4 inducers (e.g., carbamazepine): Decrease plasma concentrations of risperidone. ( 2.6 , 7.1 ) 7.1 Drugs Having Clinically Important Interactions with UZEDY Table 13 includes clinically significant drug interactions with UZEDY. Table 13: Clinically Important Drug Interactions with UZEDY Strong CYP2D6 Inhibitors Clinical Impact: Concomitant use of UZEDY with strong CYP2D6 inhibitors may increase the plasma exposure of risperidone and lower the plasma exposure of a major active metabolite, 9-hydroxyrisperidone [see Clinical Pharmacology ( 12.3 )] . Intervention: When initiation of strong CYP2D6 inhibitors is considered, patients may be placed on the lowest dose (50 mg once monthly or 100 mg once every 2 months) of UZEDY prior to the planned start of strong CYP2D6 inhibitors to adjust for the expected increase in plasma concentrations of risperidone. When strong CYP2D6 inhibitors are initiated in patients receiving UZEDY 50 mg once monthly or 100 mg once every 2 months, it is recommended to continue treatment with the same dose unless clinical judgment necessitates interruption of UZEDY treatment. The effects of discontinuation of strong CYP2D6 inhibitors on the pharmacokinetics of risperidone and 9-hydroxyrisperidone have not been studied [see Clinical Pharmacology ( 12.3 )] . Strong CYP3A4 Inducers Clinical Impact: Concomitant use of UZEDY and a strong CYP3A4 inducer may cause decreases in the combined plasma concentrations of risperidone and 9-hydroxyrisperidone which could lead to decreased efficacy of UZEDY [see Clinical Pharmacology ( 12.3 )] . Intervention: Changes in efficacy and safety should be carefully monitored with any dose adjustment of UZEDY. At the initiation of therapy with a strong CYP3A4 inducer, patients should be closely monitored during the first 4 to 8 weeks. In patients receiving UZEDY at a specific dose, consider increasing the dose to the next highest dose. In patients receiving UZEDY 125 mg once monthly or 250 mg once every 2 months, additional oral risperidone therapy may need to be considered. On discontinuation of a strong CYP3A4 inducer, the dosage of UZEDY or any additional oral risperidone therapy should be reevaluated and, if necessary, decreased to adjust for the expected increase in plasma concentration of risperidone and 9-hydroxyrisperidone. For patients treated with UZEDY 50 mg once monthly or UZEDY 100 mg once every 2 months discontinuing from a strong CYP3A4 inducer, it is recommended to continue treatment with the same dose unless clinical judgment necessitates interruption of UZEDY treatment [see Dosage and Administration ( 2.6 )] . Centrally-Acting Drugs and Alcohol Clinical Impact: Due to additive pharmacologic effects, the concomitant use of centrally-acting drugs, including alcohol, may increase nervous system disorders. Intervention: Caution should be used when UZEDY is administered in combination with other centrally-acting drugs or alcohol. Hypotensive Agents Clinical Impact: Because of its potential for inducing hypotension, UZEDY may enhance the hypotensive effects of other therapeutic agents with this potential. Intervention: Caution should be used when UZEDY is administered with other therapeutic effects of other therapeutic agents with this potential. Dopamine Agonists Clinical Impact: Agents with central antidopaminergic activity such as UZEDY may antagonize the pharmacologic effects of dopamine agonists. Intervention: Caution should be used when UZEDY is administered in combination with levodopa and dopamine agonists. Methylphenidate Clinical Impact: Concomitant use with methylphenidate, when there is change in dosage of either medication, may increase the risk of extrapyramidal symptoms (EPS) [see Adverse Reactions ( 6.2 )] . Intervention: Monitor for symptoms of EPS with concomitant use of UZEDY and methylphenidate. 7.2 Drugs Having No Clinically Important Interactions with UZEDY Based on pharmacokinetic studies with oral risperidone, no dosage adjustment of UZEDY is required when administered concomitantly with amitriptyline, cimetidine, ranitidine, clozapine, topiramate, and moderate CYP3A4 inhibitors (erythromycin). Additionally, no dosage adjustment is necessary for lithium, valproate, topiramate, digoxin, and CYP2D6 substrates (donepezil and galantamine) when co-administered with UZEDY [see Clinical Pharmacology ( 12.3 )] .
