Boxed Warning

Additions and/or revisions underlined:

WARNING: ABUSE, MISUSE, AND ADDICTION

Ritalin LA has a high potential for abuse and misuse, which can lead to the development of a substance use disorder, including addiction. Misuse and abuse of CNS stimulants, including Ritalin LA, 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 Ritalin LA, assess each patient’s risk for abuse, misuse, and addiction. Educate patients and their families about these risks, proper storage of the drug, and proper disposal of any unused drug. Throughout Ritalin LA treatment, reassess each patient’s risk of abuse, misuse, and addiction and frequently monitor for signs and symptoms of abuse, misuse, and addiction [see Warnings and Precautions (5.1), Drug Abuse and Dependence (9.2)].

5 Warnings and Precautions

5.1 Abuse, Misuse, and Addiction

Additions and/or revisions underlined:

Ritalin LA has a high potential for abuse and misuse. The use of Ritalin LA exposes individuals to the risks of abuse and misuse, which can lead to the development of a substance use disorder, including addiction. Ritalin LA 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 Ritalin LA, 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 Ritalin LA, 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 Ritalin LA in a safe place, preferably locked, and instruct patients to not give Ritalin LA to anyone else. Throughout Ritalin LA treatment, reassess each patient’s risk of abuse, misuse, and addiction and frequently monitor for signs and symptoms of abuse, misuse, and addiction.

5.10 Motor and Verbal Tics, and Worsening of Tourette’s Syndrome

New subsection added:

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 Ritalin LA, assess the family history and clinically evaluate patients for tics or Tourette’s syndrome. Regularly monitor Ritalin LA-treated patients for the emergence or worsening of tics or Tourette’s syndrome and discontinue treatment if clinically appropriate.

5.8 Acute Angle Closure Glaucoma

New subsection added:

There have been reports of angle closure glaucoma associated with methylphenidate treatment.

Although the mechanism is not clear, Ritalin LA-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

New subsection added:

There have been reports of an elevation of intraocular pressure (IOP) associated with methylphenidate treatment [see Adverse Reactions (6.2)].

Prescribe Ritalin LA to patients with open-angle glaucoma or abnormally increased IOP only if the benefit of treatment is considered to outweigh the risk. Closely monitor Ritalin LA-treated patients with a history of abnormally increased IOP or open angle glaucoma

6 Adverse Reactions

Additions and/or revisions underlined:

The following are discussed in more detail in other sections of the labeling:

8.1 Pregnancy

(Pregnancy and Lactation Labeling Rule (PLLR) Conversion; Extensive changes: please refer to labeling)

8.2 Lactation

(Pregnancy and Lactation Labeling Rule (PLLR) Conversion; Additions and/or revisions underlined)

Risk Summary

Limited published literature, based on milk sampling from seven mothers reports that methylphenidate is present in human milk, which resulted in infant doses of 0.16% to 0.7% of the maternal weight-adjusted dosage and a milk/plasma ratio ranging between 1.1 and 2.7. There are no reports of adverse effects on the breastfed infant and no effects on milk production. Long-term neurodevelopmental effects on infants from stimulant exposure are unknown. The developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for RITALIN or RITALIN-SR and any potential adverse effects on the breastfed infant from RITALIN or RITALIN-SR or from the underlying maternal condition.

Clinical Considerations

Monitor breastfeeding infants for adverse reactions, such as agitation, insomnia, anorexia, and reduced weight gain.

8.4 Pediatric Use

(Additions and/or revisions underlined)

The safety and effectiveness of Ritalin and Ritalin-SR for the treatment of ADHD have been established in pediatric patients 6 to 17 years.

The safety and effectiveness of Ritalin and Ritalin-SR in pediatric patients less than 6 years have not been established. The long-term efficacy of Ritalin and Ritalin-SR in pediatric patients has not been established.

Long-Term Suppression of Growth

Growth should be monitored during treatment with stimulants, including Ritalin and Ritalin-SR. Pediatric patients who are not growing or gaining weight as expected may need to have their treatment interrupted.

Juvenile Animal Toxicity Data

Rats treated with methylphenidate early in the postnatal period through sexual maturation demonstrated a decrease in spontaneous locomotor activity in adulthood. A deficit in acquisition of a specific learning task was observed in females only. The doses at which these findings were observed are at least 4 times the MRHD of 60 mg/day given to children on a mg/m2 basis.

In a study conducted in young rats, methylphenidate was administered orally at doses of up to 100 mg/kg/day for 9 weeks, starting early in the postnatal period (postnatal Day 7) and continuing through sexual maturity (postnatal Week 10). When these animals were tested as adults (postnatal Weeks 13 to 14), decreased spontaneous locomotor activity was observed in males and females previously treated with 50 mg/kg/day (approximately 4 times the MRHD of 60 mg/day given to children on a mg/m2 basis) or greater, and a deficit in the acquisition of a specific learning task was seen in females exposed to the highest dose (8 times the MRHD given to children on a mg/m2 basis). The no effect level for juvenile neurobehavioral development in rats was 5 mg/kg/day ( approximately 0.5 times the MRHD given to children on a mg/m2 basis). The clinical significance of the long-term behavioral effects observed in rats is unknown.
