Daytrana Drug Information

Clinical Trials Experience

Because clinical trials are conducted under widely varying conditions, adverse reactions 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. The most commonly reported (frequency ≥ 5% and twice the rate of placebo) adverse reactions in a controlled trial in children aged 6-12 included appetite decreased, insomnia, nausea, vomiting, weight decreased, tic, affect lability, and anorexia. The most commonly reported (frequency ≥ 5% and twice the rate of placebo) adverse reactions in a controlled trial in adolescents aged 13-17 were appetite decreased, nausea, insomnia, weight decreased, dizziness, abdominal pain, and anorexia . The most common (≥ 2% of subjects) adverse reaction associated with discontinuations in double-blind clinical trials in children or adolescents was application site reactions . The overall DAYTRANA development program included exposure to DAYTRANA in a total of 2,152 participants in clinical trials, including 1,529 children aged 6-12, 223 adolescents aged 13-17, and 400 adults.

The 1,752 child and adolescent subjects aged 6-17 years were evaluated in 10 controlled clinical studies, 7 open-label clinical studies, and 5 clinical pharmacology studies. In a combined studies pool of children using DAYTRANA with a wear time of 9 hours, 212 subjects were exposed for ≥ 6 months and 115 were exposed for ≥ 1 year; 85 adolescents were exposed for ≥ 6 months. Most patients studied were exposed to DAYTRANA transdermal system sizes of 12.5 cm 2, 18.75 cm 2, 25 cm 2 or 37.5 cm 2, with a wear time of 9 hours.

In the data presented below, the adverse reactions reported during exposure were obtained primarily by general inquiry at each visit, and were recorded by the clinical investigators using terminology of their own choosing. Consequently, it is not possible to provide a meaningful estimate of the proportion of individuals experiencing adverse reactions without first grouping similar types of events into a smaller number of standardized event categories. Adverse Reactions in Clinical Studies with Discontinuation of Treatment In a 7-week double-blind, parallel-group, placebo-controlled study in children with ADHD conducted in the outpatient setting, 7.1% (7/98) of patients treated with DAYTRANA discontinued due to adverse events compared with 1.2% (1/85) receiving placebo.

The most commonly reported (≥ 1% and twice the rate of placebo) adverse reactions leading to discontinuation in the DAYTRANA group were application site reaction (2%), tics (1%), headache (1%), and irritability (1%). In a 7-week double-blind, parallel-group, placebo-controlled study in adolescents with ADHD conducted in the outpatient setting, 5.5% (8/145) of patients treated with DAYTRANA discontinued due to adverse reactions compared with 2.8% (2/72) receiving placebo. The most commonly reported adverse reactions leading to discontinuation in the DAYTRANA group were application site reaction (2%) and decreased appetite/anorexia (1.4%). Commonly Observed Adverse Reactions in Double-Blind, Placebo-Controlled Trials Skin Irritation and Application Site Reactions DAYTRANA is a dermal irritant. In addition to the most commonly reported adverse reactions presented in Table 2, the majority of subjects in those studies had minimal to definite skin erythema at the DAYTRANA application site.

This erythema generally caused no or minimal discomfort and did not usually interfere with therapy or result in discontinuation from treatment. Erythema is not by itself a manifestation of contact sensitization. However, contact sensitization should be suspected if erythema is accompanied by evidence of a more intense local reaction (edema, papules, vesicles) that does not significantly improve within 48 hours or spreads beyond the transdermal system site.

Most Commonly Reported Adverse Reactions Table 2 lists treatment-emergent adverse reactions reported in ≥ 1% DAYTRANA-treated children or adolescents with ADHD in two 7 week double-blind, parallel-group, placebo-controlled studies conducted in the outpatient setting. Overall, in these studies, 75.5% of children and 78.6% of adolescents experienced at least 1 adverse event. * Six subjects had affect lability, all judged as mild and described as increased emotionally sensitive, emotionality, emotional instability, emotional lability, and intermittent emotional Table 2 Number (%) of Subjects with Commonly Reported Adverse Reactions (≥ 1% in the DAYTRANA Group) in 7-Week Placebo-controlled Studies in Either Children or Adolescents - Safety Population Adolescents Children System Organ Class Preferred term Placebo N = 72 DAYTRANA N = 145 Placebo N = 85 DAYTRANA N = 98 Cardiac Disorders Tachycardia 0 1 0 1 Gastrointestinal disorders Abdominal pain 0 7 5 7 Nausea 2 14 2 12 Vomiting 1 5 4 10 Investigations Weight decreased 1 8 0 9 Metabolism and nutrition disorders Anorexia 1 7 1 5 Decreased appetite 1 37 4 25 Nervous system disorders Dizziness 1 8 1 0 Headache 9 18 10 15 Psychiatric disorders Affect lability 1 0 0 6 * Insomnia 2 9 4 13 Irritability 5 16 4 7 Tic 0 0 0 7 Adverse Reactions in Studies with the Long-Term Use of DAYTRANA In a long-term open-label study of up to 12 months duration in 326 children wearing DAYTRANA 9 hours daily, the most common (≥ 10%) adverse reactions were decreased appetite, headache, and weight decreased. A total of 30 subjects (9.2%) were withdrawn from the study due to adverse events and 22 additional subjects (6.7%) discontinued treatment as the result of an application site reaction.

Other than application site reactions, affect lability (5 subjects, 1.5%) was the only additional adverse reaction leading to discontinuation reported with a frequency of greater than 1%. In a long-term open-label study of up to 6 months duration in 162 adolescents wearing DAYTRANA 9 hours daily, the most common (≥ 10%) adverse reactions were decreased appetite and headache. A total of 9 subjects (5.5%) were withdrawn from the study due to adverse events and 3 additional subjects (1.9%) discontinued treatment as the result of an application site reaction. Other adverse reactions leading to discontinuation that occurred with a frequency of greater than 1% included affect lability and irritability (2 subjects each, 1.2%).

Postmarketing Experience

In addition, the following adverse reactions have been identified during the post-approval use of DAYTRANA. Because these reactions are reported voluntarily from a population of uncertain size, it is not possible to reliably estimate their frequency or establish a causal relationship to DAYTRANA exposure. Cardiac Disorders: palpitations. Eye Disorders: visual disturbances, blurred vision, increased intraocular pressure, mydriasis, and accommodation disorder.

General Disorders and Administration Site Disorders : fatigue, application site reactions such as bleeding, bruising, burn, burning, dermatitis, discharge, discoloration, discomfort, dryness, eczema, edema, erosion, erythema, excoriation, exfoliation, fissure, hyperpigmentation, hypopigmentation, induration, infection, inflammation, irritation, pain, papules, paresthesia, pruritus, rash, scab, swelling, ulcer, urticaria, vesicles, and warmth. Immune System Disorders: hypersensitivity reactions including generalized erythematous and urticarial rashes, allergic contact dermatitis, angioedema, and anaphylaxis. Investigations: blood pressure increased.

Nervous System Disorders : convulsion, dyskinesia, lethargy, somnolence, serotonin syndrome in combination with serotonergic drugs, and extrapyramidal disorder, motor, and verbal tics. Psychiatric Disorders : depression, hallucination, nervousness, and libido changes. Skin and Subcutaneous Tissue Disorders : alopecia.

Adverse Reactions with Oral Methylphenidate Products Nervousness and insomnia are the most common adverse reactions reported with other methylphenidate products. In children, loss of appetite, abdominal pain, weight loss during prolonged therapy, insomnia, and tachycardia may occur more frequently; however, any of the other adverse reactions listed below may also occur. Other reactions include: Cardiac Disorders: angina, arrhythmia, and pulse increased or decreased.

Immune System Disorders: hypersensitivity reactions including skin rash, urticaria, fever, arthralgia, exfoliative dermatitis, erythema multiforme with histopathological findings of necrotizing vasculitis, and thrombocytopenic purpura. Metabolism and Nutrition Disorders: anorexia and weight loss during prolonged therapy. Nervous System Disorders: drowsiness, rare reports of Tourette's syndrome and toxic psychosis.

Very rare reports of neuroleptic malignant syndrome (NMS) have been received, and, in most of these, patients were concurrently receiving therapies associated with NMS. In a single report, a ten-year-old boy who had been taking methylphenidate for approximately 18 months experienced an NMS-like event within 45 minutes of ingesting his first dose of venlafaxine. It is uncertain whether this case represented a drug-drug interaction, a response to either drug alone, or some other cause. Vascular Disorders: blood pressure increased or decreased and cerebral arteritis and/or occlusion.

Although a definite causal relationship has not been established, the following have been reported in patients taking methylphenidate: Blood and Lymphatic System Disorders: leukopenia and/or anemia. Hepatobiliary Disorders: abnormal liver function, ranging from transaminase elevation to severe hepatic injury. Psychiatric Disorders: transient depressed mood.

Skin and Subcutaneous Tissue Disorders: scalp hair loss. Musculoskeletal and Connective Tissue Disorders: rhabdomyolysis.

Monoamine Oxidase Inhibitors (MAOI)

Concomitant use of MAOIs and CNS stimulants, including DAYTRANA, can cause hypertensive crisis. Potential outcomes include death, stroke, myocardial infarction, aortic dissection, ophthalmological complications, eclampsia, pulmonary edema, and renal failure . Concomitant use of DAYTRANA with MAOIs or within 14 days after discontinuing MAOI treatment is contraindicated.

Antihypertensive Drugs

DAYTRANA may decrease the effectiveness of drugs used to treat hypertension. Monitor blood pressure and adjust the dosage of the antihypertensive drug as needed .

Coumarin Anticoagulants, Antidepressants, and Selective

Serotonin Reuptake Inhibitors Human pharmacologic studies have shown that methylphenidate may inhibit the metabolism of coumarin anticoagulants, anticonvulsants (e.g., phenobarbital, phenytoin, primidone), and some tricyclic drugs (e.g., imipramine, clomipramine, desipramine) and selective serotonin reuptake inhibitors. Downward dose adjustments of these drugs may be required when given concomitantly with methylphenidate. It may be necessary to adjust the dosage and monitor plasma drug concentrations (or, in the case of coumarin, coagulation times), when initiating or discontinuing methylphenidate.

Halogenated Anesthetics

Concomitant use of halogenated anesthetics and methylphenidate may increase the risk of sudden blood pressure and heart rate increase during surgery. Avoid use of DAYTRANA in patients being treated with anesthetics on the day of surgery.

Risperidone Combined use of methylphenidate with risperidone when there is a change

in dosage, whether an increase or decrease, of either or both medications, may increase the risk of extrapyramidal symptoms (EPS). Monitor for signs of EPS.

Pregnancy Pregnancy Exposure Registry There is a pregnancy exposure registry that monitors pregnancy outcomes in women exposed to ADHD medications, including DAYTRANA, during pregnancy. Healthcare providers are encouraged to register patients by calling the National Pregnancy Registry for ADHD Medications at 1-866-961-2388 or visit https://womensmentalhealth.org/adhd-medications/. Risk Summary Published studies and post-marketing reports on methylphenidate use during pregnancy are insufficient to identify a drug-associated risk of major birth defects, miscarriage or adverse maternal or fetal outcomes. There are risks to the fetus associated with the use of CNS stimulants during pregnancy ( see Clinical Considerations ). No effects on morphological development were observed in embryo-fetal development studies with oral administration of methylphenidate to pregnant rats and rabbits during organogenesis.

However, spina bifida was observed in rabbits when given oral doses of 200 mg/kg/day. When methylphenidate was administered orally to rats throughout pregnancy and lactation, offspring growth and survival were decreased at maternally toxic doses (see Data ). The estimated background risk of major birth defects and miscarriage for the indicated population is unknown. All pregnancies have a background risk of birth defect, loss, or other adverse outcomes.

In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinical recognized pregnancies is 2-4% and 15-20%, respectively. Clinical Considerations Fetal/Neonatal adverse reactions CNS stimulants, such as DAYTRANA, can cause vasoconstriction and thereby decrease placental perfusion. No fetal and/or neonatal adverse reactions have been reported with the use of therapeutic doses of methylphenidate during pregnancy; however, premature delivery and low birth weight infants have been reported in amphetamine-dependent mothers.

Data Animal Data Animal reproduction toxicity studies with transdermal methylphenidate have not been performed. In embryo-fetal development studies conducted in rats and rabbits, methylphenidate was administered orally to pregnant animals during the period of organogenesis, at doses up to 100 and 200 mg/kg/day, respectively. No evidence of morphological development effects was found in either of the species; however, increased incidences of fetal skeletal variations were observed in rats at 60 mg/kg or greater and an increase in fetal visceral variations was seen in rabbits at the highest dose.

In a previous study, methylphenidate was shown to have malformations (increased incidence of fetal spina bifida) in rabbits when given oral doses of 200 mg/kg/day. When methylphenidate was administered orally to rats throughout pregnancy and lactation at doses of up to 60 mg/kg/day, offspring growth and survival were decreased at maternally toxic doses. In a study in which oral methylphenidate was given to rats throughout pregnancy and lactation at doses up to 60 mg/kg/day, offspring weights and survival were decreased at 40 mg/kg/day and above; these doses caused some maternal toxicity.

Pediatric Use The safety and effectiveness of DAYTRANA have not been established in pediatric patients below the age of 6 years. In studies evaluating extended-release methylphenidate products, patients 4 to <6 years of age had higher systemic methylphenidate exposures than those observed in older pediatric patients at the same dosage. Pediatric patients 4 to <6 years of age also had a higher incidence of adverse reactions, including weight loss.

The safety and effectiveness of DAYTRANA for the treatment of ADHD have been established in pediatric patients 6 to 17 years. Long Term Suppression of Growth Growth should be monitored during treatment with stimulants, including DAYTRANA. Children 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.

Studies with transdermal methylphenidate have not been performed in juvenile animals. 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 13-14), decreased spontaneous locomotor activity was observed in males and females previously treated with 50 mg/kg/day or greater, and a deficit in the acquisition of a specific learning task was seen in females exposed to the highest dose. The no effect level for juvenile neurobehavioral development in rats was 5 mg/kg/day.

The clinical significance of the long-term behavioral effects observed in rats is unknown.

Hypersensitivity to Methylphenidate

DAYTRANA is contraindicated in patients known to be hypersensitive to methylphenidate or other components of the product (polyester/ethylene vinyl acetate laminate film backing, acrylic adhesive, silicone adhesive, and fluoropolymer-coated polyester) .

Monoamine Oxidase Inhibitors

DAYTRANA is contraindicated during treatment with monoamine oxidase inhibitors, and within a minimum of 14 days following discontinuation of treatment with a monoamine oxidase inhibitor (hypertensive crises may result).

Clinical Effects of Overdose Overdose of CNS stimulants is characterized by the following sympathomimetic effects: Cardiovascular effects including tachyarrhythmias, and hypertension or hypotension. Vasospasm, myocardial infarction, or aortic dissection may precipitate sudden cardiac death. Takotsubo cardiomyopathy may develop.

CNS effects including psychomotor agitation, confusion, and hallucinations. Serotonin syndrome, seizures, cerebral vascular accidents, and coma may occur. Life-threatening hyperthermia (temperatures greater than 104°F) and rhabdomyolysis may develop.

Overdose Management Consider the possibility of multiple drug ingestion. Because methylphenidate has a large volume of distribution and is rapidly metabolized, dialysis is not useful. Remove all transdermal systems immediately and cleanse the area(s) to remove any remaining adhesive.

The continuing absorption of methylphenidate from the skin, even after removal of the transdermal system, should be considered when treating patients with overdose. Consider contacting the Poison Help line (1-800-222-1222) or a medical toxicologist for additional overdose management recommendations.
