Warnings & Precautions
Risks to Patients with Serious Cardiac Disease: Avoid use in patients with known structural cardiac abnormalities, cardiomyopathy, serious cardiac arrhythmias, coronary artery disease, or other serious cardiac disease. (5.2) Increased Blood Pressure and Heart Rate: Monitor blood pressure and pulse. (5.3) Psychiatric Adverse Reactions: Prior to initiating methylphenidate hydrochloride extended-release, screen patients for risk factors for developing a manic episode. If new psychotic or manic symptoms occur, consider discontinuing methylphenidate hydrochloride extended-release. (5.4) Priapism: If abnormally sustained or frequent and painful erections occur, patients should seek immediate medical attention. (5.5) Peripheral Vasculopathy, including Raynaud’s Phenomenon: Careful observation for digital changes is necessary during methylphenidate hydrochloride extended-release treatment. Further clinical evaluation (e.g., rheumatology referral) may be appropriate for patients who develop signs or symptoms of peripheral vasculopathy. (5.6) Long-Term Suppression of Growth in Pediatric Patients: Closely monitor growth (height and weight) in pediatric patients. Pediatric patients not growing or gaining height or weight as expected may need to have their treatment interrupted. (5.7) Acute Angle Closure Glaucoma: Methylphenidate hydrochloride extended-release-treated patients considered at risk for acute angle closure glaucoma (e.g., patients with significant hyperopia) should be evaluated by an ophthalmologist. (5.8) Increased Intraocular Pressure (IOP) and Glaucoma: Prescribe methylphenidate hydrochloride extended-release to patients with open-angle glaucoma or abnormally increased IOP only if the benefit of treatment is considered to outweigh the risk. Closely monitor patients with a history of increased IOP or open angle glaucoma. (5.9) Motor and Verbal Tics, and Worsening of Tourette’s Syndrome: Before initiating methylphenidate hydrochloride extended-release, assess the family history and clinically evaluate patients for tics or Tourette’s syndrome. Regularly monitor patients for the emergence or worsening of tics or Tourette’s syndrome. Discontinue treatment if clinically appropriate. (5.10) 5.1 Abuse, Misuse, and Addiction Methylphenidate hydrochloride extended-release has a high potential for abuse and misuse. The use of methylphenidate hydrochloride extended-release exposes individuals to the risks of abuse and misuse, which can lead to the development of a substance use disorder, including addiction. Methylphenidate hydrochloride extended-release can be diverted for non-medical use into illicit channels or distribution [see Drug Abuse and Dependence (9.2) ] . Misuse and abuse of CNS stimulants, including methylphenidate hydrochloride extended-release, can result in overdose and death [see Overdosage (10) ] , and this risk is increased with higher doses or unapproved methods of administration, such as snorting or injection. Before prescribing methylphenidate hydrochloride extended-release, assess each patient’s risk for abuse, misuse, and addiction. Educate patients and their families about these risks and proper disposal of any unused drug. Advise patients to store methylphenidate hydrochloride extended-release in a safe place, preferably locked, and instruct patients to not give methylphenidate hydrochloride extended-release to anyone else. Throughout methylphenidate hydrochloride extended-release treatment, reassess each patient’s risk of abuse, misuse, and addiction and frequently monitor for signs and symptoms of abuse, misuse, and addiction. 5.2 Risks to Patients with Serious Cardiac Disease Sudden death has been reported in patients with structural cardiac abnormalities or other serious cardiac disease who were treated with CNS stimulants at the recommended dosage. Avoid methylphenidate hydrochloride extended-release use in patients with known structural cardiac abnormalities, cardiomyopathy, serious cardiac arrhythmia, coronary artery disease, or other serious cardiac problems. 5.3 Increased Blood Pressure and Heart Rate CNS stimulants cause an increase in blood pressure (mean increase approximately 2 mmHg to 4 mmHg) and heart rate (mean increase approximately 3 bpm to 6 bpm). Some patients may have larger increases. Monitor all methylphenidate hydrochloride extended-release-treated patients for hypertension and tachycardia. 5.4 Psychiatric Adverse Reactions Exacerbation of Pre-Existing Psychosis CNS stimulants may exacerbate symptoms of behavior disturbance and thought disorder in patients with a pre-existing psychotic disorder. Induction of a Manic Episode in Patients with Bipolar Disorder CNS stimulants may induce a manic or mixed episode in patients. Prior to initiating methylphenidate hydrochloride extended-release treatment, screen patients for risk factors for developing a manic episode (e.g., comorbid or history of depressive symptoms or a family history of suicide, bipolar disorder, or depression). New Psychotic or Manic Symptoms CNS stimulants, at recommended dosages, may cause psychotic or manic symptoms (e.g., hallucinations, delusional thinking, or mania) in patients without a prior history of psychotic illness or mania. In a pooled analysis of multiple short-term, placebo-controlled studies of CNS stimulants, psychotic or manic symptoms occurred in approximately 0.1% of CNS stimulant-treated patients, compared to 0% of placebo-treated patients. If such symptoms occur, consider discontinuing methylphenidate hydrochloride extended-release. 5.5 Priapism Prolonged and painful erections, sometimes requiring surgical intervention, have been reported with methylphenidate use in both adult and pediatric male patients. Although priapism was not reported with methylphenidate initiation, it developed after some time on methylphenidate, often subsequent to an increase in dosage. Priapism also occurred during methylphenidate withdrawal (drug holidays or during discontinuation). Methylphenidate hydrochloride extended-release-treated patients who develop abnormally sustained or frequent and painful erections should seek immediate medical attention. 5.6 Peripheral Vasculopathy, including Raynaud’s Phenomenon CNS stimulants, including methylphenidate hydrochloride extended-release, used to treat ADHD are associated with peripheral vasculopathy, including Raynaud’s phenomenon. Signs and symptoms are usually intermittent and mild; however, sequelae have included digital ulceration and/or soft tissue breakdown. Effects of peripheral vasculopathy, including Raynaud’s phenomenon, were observed in post-marketing reports and at the therapeutic dosages of CNS stimulants in all age groups throughout the course of treatment. Signs and symptoms generally improved after dosage reduction in or discontinuation of the CNS stimulant. Careful observation for digital changes is necessary during methylphenidate hydrochloride extended-release treatment. Further clinical evaluation (e.g., rheumatology referral) may be appropriate for methylphenidate hydrochloride extended-release-treated patients who develop signs of symptoms of peripheral vasculopathy. 5.7 Long-Term Suppression of Growth in Pediatric Patients Methylphenidate hydrochloride extended-release is not approved for use and is not recommended in pediatric patients below 6 years of age [see Use in Specific Population (8.4) ] . CNS stimulants have been associated with weight loss and slowing of growth rate in pediatric patients. Careful follow-up of weight and height in children ages 7 to 10 years who were randomized to either methylphenidate or non-medication treatment groups over 14 months, as well as in naturalistic subgroups of newly methylphenidate-treated and non-medication treated children over 36 months (to the ages of 10 to 13 years), suggests that pediatric patients who received methylphenidate treatment for 7 days per week throughout the year had a temporary slowing in growth rate (on average, a total of about 2 cm less growth in height and 2.7 kg less growth in weight over 3 years), without evidence of growth rebound during this development period. Closely monitor growth (weight and height) in methylphenidate hydrochloride extended-release-treated pediatric patients. Pediatric patients who are not growing or gaining height or weight as expected may need to have their treatment interrupted. 5.8 Acute Angle Closure Glaucoma There have been reports of angle closure glaucoma associated with methylphenidate treatment. Although the mechanism is not clear, methylphenidate hydrochloride extended-release-treated patients considered at risk for acute angle closure glaucoma (e.g., patients with significant hyperopia) should be evaluated by an ophthalmologist. 5.9 Increased Intraocular Pressure and Glaucoma There have been reports of an elevation of intraocular pressure (IOP) associated with methylphenidate treatment [see Adverse Reactions (6.2) ] . Prescribe methylphenidate hydrochloride extended-release to patients with open-angle glaucoma or abnormally increased IOP only if the benefit of treatment is considered to outweigh the risk. Closely monitor methylphenidate hydrochloride extended-release-treated patients with a history of abnormally increased IOP or open angle glaucoma. 5.10 Motor and Verbal Tics, and Worsening of Tourette’s Syndrome CNS stimulants, including methylphenidate, have been associated with the onset or exacerbation of motor and verbal tics. Worsening of Tourette’s syndrome has also been reported [see Adverse Reactions (6.2) ] . Before initiating methylphenidate hydrochloride extended-release, assess the family history and clinically evaluate patients for tics or Tourette’s syndrome. Regularly monitor methylphenidate hydrochloride extended-release -treated patients for the emergence or worsening of tics or Tourette’s syndrome, and discontinue treatment if clinically appropriate.

( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact Amneal Pharmaceuticals at 1-877-835-5472 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch. 6.1 Clinical Trials Experience 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. Clinical trials experience with methylphenidate hydrochloride extended-release included 188 pediatric patients 6 to 15 years old with ADHD exposed to methylphenidate hydrochloride extended-release. Patients received methylphenidate hydrochloride extended-release 20 mg, 40 mg, and/or 60 mg per day. The 188 patients were evaluated in the following studies: Study 1, a 3-week placebo-controlled clinical study consisting of a total of 314 pediatric patients (ages 6 to 15 years; methylphenidate hydrochloride extended-release n=155); Study 2, a placebo-controlled, crossover clinical study consisting of 25 pediatric patients (ages 7 to 12 years); and Study 3, an uncontrolled clinical study consisting of 8 pediatric patients (ages 6 to 10 years). Adverse Reactions Leading to Discontinuation of Treatment In the 3-week placebo-controlled, parallel-group trial, two methylphenidate hydrochloride extended-release-treated patients (1%) and no placebo-treated patients discontinued due to an adverse reaction (rash and pruritus; and headache, abdominal pain, and dizziness, respectively). Most Common Adverse Reactions The most common adverse reactions that occurred in 5% or more of patients treated with methylphenidate hydrochloride extended-release in a pool of Studies 1, 2 and 3 (ages 6 to 15 years) where the incidence in patients treated with methylphenidate hydrochloride extended-release was at least twice the incidence in placebo-treated patients were anorexia and insomnia. Adverse reactions that occurred in ≥ 5% of patients treated with methylphenidate hydrochloride extended-release and greater than placebo in pooled Studies 1, 2, and 3 are presented in Table 2: Table 2: Adverse Reactions (≥ 5% and Greater than Placebo) in Pediatric Patients Ages 6 to 15 Years Receiving Methylphenidate Hydrochloride Extended-Release in Pooled Three to Four Week Trials Body System Preferred Term Methylphenidate Hydrochloride Extended-Release (n=188) % Placebo (n=190) % General Headache 12 8 Abdominal Pain (stomachache) 7 4 Digestive System Anorexia 9 2 Nervous System Insomnia 5 2 6.2 Post-marketing Experience The following adverse reactions have been identified during post-marketing use of methylphenidate hydrochloride extended-release and other methylphenidate hydrochloride products.
