1 INDICATIONS AND USAGE Methylphenidate hydrochloride extended-release tablets are indicated for the treatment of attention deficit hyperactivity disorder (ADHD) in patients aged 6 to 65 years old. Limitations of Use The use of methylphenidate hydrochloride extended-release tablets are not recommended in pediatric patients younger than 6 years of age because they had higher plasma exposure and a higher incidence of adverse reactions (e.g., weight loss) than patients 6 years and older at the same dosage [see Warnings and Precautions (5.7) and Use in Specific Populations (8.4)]. Methylphenidate hydrochloride extended-release tablets are a CNS stimulant indicated for the treatment of attention deficit hyperactivity disorder (ADHD) in patients aged 6 to 65 years old. (1) Limitations of Use The use of methylphenidate hydrochloride extended-release tablets are not recommended in pediatric patients younger than 6 years of age because they had higher plasma exposure and a higher incidence of adverse reactions (e.g., weight loss) than patients 6 years and older at the same dosage (5.7, 8.4).

2 DOSAGE AND ADMINISTRATION Prior to initiating methylphenidate hydrochloride extended-release tablets treatment assess for (2.1): o the presence of cardiac disease o for family history of tics or Tourette’ syndrome and clinically evaluate patients for motor or verbal tics or Tourette’s syndrome Administer once daily in the morning with or without food. Swallow whole with liquids; do not chew, divide, or crush. (2.2) Recommended dosage in pediatric patients 6 to 17 years of age new to methylphenidate hydrochloride extended-release tablets: starting dosage is18 mg once daily. May be increased weekly in 18 mg increments. Maximum dosage for pediatric patients (2.3): o 6 to 12 years: 54 mg once daily o 13 to 17 years: 72 mg once daily Recommended dosage in adults (up to 65 years of age) new to methylphenidate hydrochloride extended-release tablets: starting dosage is 18 mg or 36 mg once daily. May be increased weekly in 18 mg increments, up to 72 mg once daily. (2.3) ​Patients currently using immediate-release methylphenidate: starting methylphenidate hydrochloride extended-release tablets dosage is based on current dosage regimen. (2.4)​ 2.1 Pretreatment Screening Prior to treating patients with methylphenidate hydrochloride extended-release tablets, assess: For the presence of cardiac disease (e.g., perform a careful history, family history of sudden death or ventricular arrhythmia, and physical exam) [see Warnings and Precautions (5.2)]. The family history for tics or Tourette’ syndrome and clinically evaluate patients for motor or verbal tics or Tourette’s syndrome [see Warnings and Precautions (5.11)]. 2.2 Important Administration Instructions Administer methylphenidate hydrochloride extended-release tablets orally once daily in the morning with or without food. Swallow methylphenidate hydrochloride extended-release tablets whole with liquids. Do not split, crush, or chew the extended-release tablets because doing so will compromise the extended-release characteristics of methylphenidate hydrochloride extended-release tablets and may compromise the effectiveness or safety of methylphenidate hydrochloride extended-release tablets. 2.3 Recommended Methylphenidate Hydrochloride Extended-Release Tablets Dosage in Patients New to Methylphenidate See Table 1 for the recommended once-daily dosage of methylphenidate hydrochloride extended-release tablets in patients who were not taking a methylphenidate product. In patients who have not achieved an optimal response at a lower dosage, increase the methylphenidate hydrochloride extended-release tablets dosage in 18 mg increments at weekly intervals. However, if a slower titration is recommended for patients who have not achieved an optimal response taking 18 mg of methylphenidate hydrochloride extended-release tablets once daily, increase their daily dosage to 27 mg once per day.

The maximum recommended dosage in pediatric patients 6 to 12 years of age is 54 mg/day, and the maximum recommended dosage in patients 13 to 65 years old is 72 mg/day. 2.5 Dosage Reduction and Discontinuation If paradoxical aggravation of ADHD symptoms or methylphenidate hydrochloride extended-release tablets -associated adverse reactions occur, reduce the methylphenidate hydrochloride extended-release tablets dosage or, if necessary, discontinue methylphenidate hydrochloride extended-release tablets. If ADHD improvement is not observed after appropriate dosage modification over a one-month period, discontinue methylphenidate hydrochloride extended-release tablets.

5 WARNINGS AND 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 tablets, screen patients for risk factors for developing a manic episode. If new psychotic or manic symptoms occur, consider discontinuing methylphenidate hydrochloride extended-release tablets. (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: Carefully assess for digital changes during methylphenidate hydrochloride extended-release tablets 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) Risk of Gastrointestinal (GI) Obstruction in Patients with GI Narrowing: Only use in patients able to swallow the extended-release tablet whole, and should not ordinarily be used in patients with pre-existing severe GI narrowing. (5.8) Acute Angle Closure Glaucoma: Methylphenidate hydrochloride extended-release tablets-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 (IOP) and Glaucoma: Prescribe methylphenidate hydrochloride extended-release tablets 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. (5.10) Motor and Verbal Tics, and Worsening of Tourette’s Syndrome: Before initiating methylphenidate hydrochloride extended-release tablets, 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. (5.11) 5.1 Abuse, Misuse, and Addiction Methylphenidate hydrochloride extended-release tablets have a high potential for abuse and misuse. The use of methylphenidate hydrochloride extended-release tablets exposes individuals to the risks of abuse and misuse, which can lead to the development of a substance use disorder, including addiction [see Drug Abuse and Dependence (9.1, 9.2)] . Misuse and abuse of CNS stimulants, including methylphenidate hydrochloride extended-release tablets, can result in overdose and death [see Overdosage (10)] , and this risk is increased with higher dosage or unapproved methods of administration, such as snorting or injection. Before prescribing methylphenidate hydrochloride extended-release tablets, 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 tablets in a safe place, preferably locked, and instruct patients to not give methylphenidate hydrochloride extended-release tablets to anyone else. Throughout methylphenidate hydrochloride extended-release tablets 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 ADHD dosage. Avoid methylphenidate hydrochloride extended-release tablets use in patients with known structural cardiac abnormalities, cardiomyopathy, serious cardiac arrhythmia, coronary artery disease, or other serious cardiac disease. 5.3 Increased Blood Pressure and Heart Rate CNS stimulants may cause an increase in blood pressure (mean increase approximately 2 to 4 mmHg) and heart rate (mean increase approximately 3 to 6 beats per minute) [see Adverse Reactions (6)]. Some patients may have larger increases. Monitor all methylphenidate hydrochloride extended-release tablets-treated patients for hypertension and tachycardia. 5.4 Psychiatric Adverse Reactions Exacerbation of Psychosis in Patients with a Psychotic Disorder CNS stimulants, including methylphenidate hydrochloride extended-release tablets, may exacerbate 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, including methylphenidate hydrochloride extended-release tablets, may induce a manic or mixed episode in patients with bipolar disorder. Prior to initiating methylphenidate hydrochloride extended-release tablets treatment, screen patients for risk factors for developing a manic episode (e.g., history of depressive symptoms or a family history of suicide, bipolar disorder, or depression). New Psychotic or Manic Symptoms in Patients without a History of a Bipolar or Psychotic Disorder CNS stimulants (including methylphenidate hydrochloride extended-release tablets), at the recommended dosage, 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 with 0% of placebo-treated patients. If such symptoms occur, consider discontinuing methylphenidate hydrochloride extended-release tablets. 5.5 Priapism Prolonged and painful erections, sometimes requiring surgical intervention, have been reported with methylphenidate use in adult and pediatric male patients [see Adverse Reactions (6)]. Although priapism was not reported with methylphenidate initiation, priapism occurred in patients treated with methylphenidate after some time, often subsequent to an increase in dosage. Priapism also occurred during methylphenidate withdrawal (drug holidays or during discontinuation). Methylphenidate hydrochloride extended-release tablets-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 tablets, used to treat ADHD are associated with peripheral vasculopathy, including Raynaud’s phenomenon [see Adverse Reactions (6.2)] . Signs and symptoms of these cases of peripheral vasculopathy were 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 of peripheral vasculopathy generally improved after CNS stimulant dosage reduction or discontinuation. During methylphenidate hydrochloride extended-release tablets treatment, carefully assess for digital changes. Further clinical evaluation (e.g., rheumatology referral) may be appropriate for methylphenidate hydrochloride extended-release tablets-treated patients who develop signs or symptoms of peripheral vasculopathy. 5.7 Long-Term Suppression of Growth in Pediatric Patients Methylphenidate hydrochloride extended-release tablets are not approved for use and is not recommended in pediatric patients below 6 years of age [see Use in Specific Populations (8.4)]. CNS stimulants have been associated with weight loss and slowing of growth rate in pediatric patients. Pediatric patients 7 to 13 years of age who received methylphenidate for 7 days per week for over 14 months to over 36 months 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 tablets -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 Risk of Gastrointestinal Obstruction in Patients with Gastrointestinal Narrowing Because methylphenidate hydrochloride extended-release tablets are nondeformable and do not appreciably change in shape in the gastrointestinal (GI) tract, methylphenidate hydrochloride extended-release tablets should not ordinarily be administered to patients with pre-existing severe pathologic or iatrogenic GI narrowing. There have been rare reports of obstructive GI symptoms in patients with known strictures in association with the ingestion of drugs in nondeformable modified-release dosage forms. Methylphenidate hydrochloride extended-release tablets should be used only in patients who are able to swallow the extended-release tablets whole [see Dosage and Administration (2.2)]. 5.9 Acute Angle Closure Glaucoma There have been reports of angle closure glaucoma associated with methylphenidate hydrochloride extended-release tablets treatment. Although the mechanism is not clear, methylphenidate hydrochloride extended-release tablets-treated patients considered at risk for acute angle closure glaucoma (e.g., patients with significant hyperopia) should be evaluated by an ophthalmologist. 5.10 Increased Intraocular Pressure and Glaucoma There have been reports of an elevation of intraocular pressure (IOP) associated with methylphenidate treatment [see Adverse Reactions (6)]. Prescribe methylphenidate hydrochloride extended-release tablets 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 tablets-treated patients with a history of abnormally increased IOP or open angle glaucoma. 5.11 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 [see Adverse Reactions (6)]. Worsening of Tourette’s syndrome has also been reported. Before initiating methylphenidate hydrochloride extended-release tablets, assess the family history for tics or Tourette’ syndrome and clinically evaluate patients for tics or Tourette’s syndrome. Regularly monitor methylphenidate hydrochloride extended-release tablets-treated patients for the emergence or worsening of tics or Tourette’s syndrome, and discontinue methylphenidate hydrochloride extended-release tablets treatment if clinically appropriate.

Blood Pressure and Heart Rate Increases • In the 1-week treatment, controlled trials in pediatric patients 6 to 12 years of age with ADHD (Studies 1 and 2) [see Clinical Studies (14.2)], both the methylphenidate hydrochloride extended-release tablets once daily group and the methylphenidate three times daily group increased resting pulse by an average of 2 to 6 beats per minute (bpm) and increased the average systolic and diastolic blood pressure roughly 1 to 4 mm Hg during the day, relative to placebo. • In the randomized withdrawal portion of the double-blind, placebo-controlled trial with pediatric patients 13 to 17 years of age with ADHD (Study 4) [see Clinical Studies (14.3)], mean increases from baseline in resting pulse rate were observed with methylphenidate hydrochloride extended-release tablets and placebo at the end of the double-blind phase (5 and 3 beats/minute (bpm), respectively). At the end of four weeks of treatment, mean increases from baseline in blood pressure for methylphenidate hydrochloride extended-release tablets and placebo-treated patients were 0.7 and 0.7 mm Hg (systolic) and 2.6 and 1.4 mm Hg (diastolic), respectively. • In the 7-week dose-titration, placebo-controlled study in adults 18 to 65 years of age with ADHD (Study 5) [see Clinical Studies (14.4)], mean changes from baseline in resting pulse rate were 3.6 in methylphenidate hydrochloride extended-release tablets -treated patients and -1.6 for placebo-treated patients after 7 weeks of treatment. Mean changes from baseline in blood pressure after 7 weeks of treatment in methylphenidate hydrochloride extended-release tablets-treated and placebo-treated patients were –1.2 and –0.5 mm Hg (systolic) and 1.1 and 0.4 mm Hg (diastolic), respectively [see Warnings and Precautions (5.3)]. • In the 5-week fixed-dose, placebo-controlled trial in adults 18 to 65 years of age with ADHD (Study 5) [see Clinical Studies (14.4)], dose-dependent mean increases of 3.9 to 9.8 bpm from baseline in standing pulse rate were observed with methylphenidate hydrochloride extended-release tablets -treated patients and 2.7 bpm with placebo-treated patients at the end of 5 weeks. Mean changes from baseline in standing blood pressure after 5 weeks of treatment ranged from 0.1 to 2.2 mm Hg (systolic) and -0.7 to 2.2 mm Hg (diastolic) for methylphenidate hydrochloride extended-release tablets-treated patients and 1.1 mm Hg (systolic) and 1.8 mm Hg (diastolic) for placebo-treated patients. table 5 6.2 Postmarketing Experience The following adverse reactions have been identified during post-approval use of methylphenidate hydrochloride extended-release tablets.
