Indications & Usage
Dexmethylphenidate hydrochloride tablets is indicated for the treatment of Attention Deficit Hyperactivity Disorder (ADHD) [see Clinical Studies (14)]. Dexmethylphenidate hydrochloride tablets is a central nervous system (CNS) stimulant indicated for the treatment of Attention Deficit Hyperactivity Disorder (ADHD) (1).
Dosage & Administration
Administer orally twice daily, 4 hours apart with or without food (2). For patients new to methylphenidate: Recommend starting dose of 5 mg once daily (2.5 mg twice daily) (2.2). For patients currently taking methylphenidate: Initiate dexmethylphenidate hydrochloride tablets therapy with half (1/2) the current total daily dose of methylphenidate (2.2). Titrate weekly in increments of 2.5 to 5 mg to a maximum of 20 mg/day (10 mg twice daily) (2.2). 2.1 Pretreatment Screening Prior to treating patients with dexmethylphenidate hydrochloride tablets, assess: for the presence of cardiac disease (i.e., perform a careful history, family history of sudden death or ventricular arrhythmia, and physical exam) [see Warnings and Precautions (5.2)]. the family history and clinically evaluate patients for motor or verbal tics or Tourette’s syndrome before initiating Dexmethylphenidate hydrochloride tablets [see Warnings and Precautions (5.10)]. 2.2 Recommended Dosage Patients New to Methylphenidate The recommended starting dose of Dexmethylphenidate hydrochloride tablets for pediatric patients who are not currently taking racemic methylphenidate, or for patients who are on stimulants other than methylphenidate, is 5 mg daily (2.5 mg twice daily) with or without food. Patients Currently on Methylphenidate The recommended starting dose of dexmethylphenidate hydrochloride tablets for pediatric patients currently using methylphenidate is half (1/2) the total daily dose of racemic methylphenidate. Titration Schedule The dose may be titrated weekly in increments of 2.5 to 5 mg to a maximum of 20 mg daily (10 mg twice daily). The dose should be individualized according to the needs and response of the patient. 2.3 Administration Instructions Dexmethylphenidate hydrochloride tablets is administered orally twice daily, at least 4 hours apart. 2.4 Dosage Reduction and Discontinuation If paradoxical aggravation of symptoms or other adverse reactions occur, reduce the dosage, or if necessary, discontinue dexmethylphenidate hydrochloride tablets. If improvement is not observed after appropriate dosage adjustment over a one-month period, the drug should be discontinued.
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 Dexmethylphenidate hydrochloride tablets, screen patients for risk factors for developing a manic episode. If new psychotic or manic symptoms occur, consider discontinuing Dexmethylphenidate hydrochloride 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: Careful observation for digital changes is necessary during Dexmethylphenidate hydrochloride 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). Acute Angle Closure Glaucoma: Dexmethylphenidate hydrochloride tablets -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 Dexmethylphenidate hydrochloride 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 (5.9). Motor and Verbal Tics, and Worsening of Tourette’s Syndrome: Before initiating Dexmethylphenidate hydrochloride 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 (5.10). 5.1 Abuse, Misuse, and Addiction Dexmethylphenidate hydrochloride tablets has a high potential for abuse and misuse. The use of Dexmethylphenidate hydrochloride tablets exposes individuals to the risks of abuse and misuse, which can lead to the development of a substance use disorder, including addiction. Dexmethylphenidate hydrochloride tablets 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 Dexmethylphenidate hydrochloride tablets, 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 Dexmethylphenidate hydrochloride 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 Dexmethylphenidate hydrochloride tablets in a safe place, preferably locked, and instruct patients to not give Dexmethylphenidate hydrochloride tablets to anyone else. Throughout Dexmethylphenidate hydrochloride 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 Dexmethylphenidate hydrochloride 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 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). Some patients may have larger increases. Monitor all Dexmethylphenidate hydrochloride tablets–treated patients for hypertension and tachycardia. 5.4 Psychiatric Adverse Reactions Exacerbation of Preexisting Psychosis CNS stimulants may exacerbate symptoms of behavior disturbance and thought disorder in patients with a preexisting psychotic disorder. Induction of a Manic Episode in Patients with Bipolar Disorder CNS stimulants may induce a manic or mixed mood episode in patients. Prior to initiating dexmethylphenidate hydrochloride tablets 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 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 to 0% of placebo-treated patients. If such symptoms occur, consider discontinuing dexmethylphenidate hydrochloride tablets. 5.5 Priapism Prolonged and painful erections, sometimes requiring surgical intervention, have been reported with methylphenidate use in both pediatric and adult 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). Dexmethylphenidate hydrochloride 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 Dexmethylphenidate hydrochloride tablets, 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 or discontinuation of the CNS stimulant. Careful observation for digital changes is necessary during Dexmethylphenidate hydrochloride tablets treatment. Further clinical evaluation (e.g., rheumatology referral) may be appropriate for Dexmethylphenidate hydrochloride tablets-treated patients who develop signs or symptoms of peripheral vasculopathy. 5.7 Long-Term Suppression of Growth in Pediatric Patients CNS stimulants have been associated with weight loss and slowing of growth rate in pediatric patients. Careful follow-up of weight and height in patients 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 patients over 36 months (to the ages of 10 to 13 years), suggests that pediatric patients who received methylphenidate 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 Dexmethylphenidate hydrochloride 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 Acute Angle Closure Glaucoma There have been reports of angle closure glaucoma associated with methylphenidate treatment. Although the mechanism is not clear, Dexmethylphenidate hydrochloride 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 and Glaucoma There have been reports of an elevation of intraocular pressure (IOP) associated with methylphenidate treatment [see Adverse Reactions (6.2)]. Prescribe Dexmethylphenidate hydrochloride 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 Dexmethylphenidate hydrochloride tablets -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 Dexmethylphenidate hydrochloride tablets, assess the family history and clinically evaluate patients for tics or Tourette’s syndrome. Regularly monitor Dexmethylphenidate hydrochloride tablets -treated patients for the emergence or worsening of tics or Tourette’s syndrome, and discontinue treatment if clinically appropriate.
