Warnings for Focalin XR
Included as part of the PRECAUTIONS section.
Precautions for Focalin XR
Abuse, Misuse, And Addiction
Focalin XR has a high potential for abuse and misuse. The use of Focalin XR exposes individuals to the risks of abuse and misuse, which can lead to the development of a substance use disorder, including addiction. Focalin XR can be diverted for non-medical use into illicit channels or distribution [see Drug Abuse And Dependence]. Misuse and abuse of CNS stimulants, including Focalin XR, can result in overdose and death [see OVERDOSAGE], and this risk is increased with higher doses or unapproved methods of administration, such as snorting or injection.
Before prescribing Focalin XR, 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 Focalin XR in a safe place, preferably locked, and instruct patients to not give Focalin XR to anyone else. Throughout Focalin XR treatment, reassess each patient’s risk of abuse, misuse, and addiction and frequently monitor for signs and symptoms of abuse, misuse, and addiction.
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 Focalin XR use in patients with known structural cardiac abnormalities, cardiomyopathy, serious cardiac arrhythmia, coronary artery disease, or other serious cardiac disease.
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 Focalin XR-treated patients for hypertension and tachycardia.
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 mood episode in patients. Prior to initiating Focalin XR treatment, screen patients for risk factors for developing 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 shortterm, 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 Focalin XR.
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).
Focalin XR-treated patients who develop abnormally sustained or frequent and painful erections should seek immediate medical attention.
Peripheral Vasculopathy, Including Raynaud’s Phenomenon
CNS stimulants, including Focalin XR, 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 at and at the therapeutic dosage 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 Focalin XR treatment. Further clinical evaluation (e.g., rheumatology referral) may be appropriate for Focalin XR-treated patients who develop signs or symptoms of peripheral vasculopathy.
Long-Term Suppression Of Growth In Pediatric Patients
CNS stimulants have been associated with weight loss and slowing of growth rate in pediatric patients.
In a 7-week, double-blind, placebo-controlled study of Focalin XR, the mean weight gain was greater for pediatric patients (ages 6 to 17 years) receiving placebo (+0.4 kg) than for patients receiving Focalin XR (-0.5 kg).
Careful follow-up of weight and height in pediatric 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 Focalin XR-treated pediatric patients. Pediatric patients who are not growing or gaining height or weight as expected may need to have their treatment interrupted.
Acute Angle Closure Glaucoma
There have been reports of angle closure glaucoma associated with methylphenidate treatment.
Although the mechanism is not clear, Focalin XR-treated patients considered at risk for acute angle closure glaucoma (e.g., patients with significant hyperopia) should be evaluated by an ophthalmologist.
Increased Intraocular Pressure And Glaucoma
There have been reports of an elevation of intraocular pressure (IOP) associated with methylphenidate treatment [see ADVERSE REACTIONS].
Prescribe Focalin to patients with open-angle glaucoma or abnormally increased IOP only if the benefit of treatment is considered to outweigh the risk. Closely monitor Focalin XR-treated patients with a history of abnormally increased IOP or open angle glaucoma.
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].
Before initiating Focalin XR, assess the family history and clinically evaluate patients for tics or Tourette’s syndrome. Regularly monitor Focalin -treated patients for the emergence or worsening of tics or Tourette’s syndrome, and discontinue treatment if clinically appropriate.
Patient Counseling Information
Advise patients to read the FDA-approved patient labeling (Medication Guide).
Abuse, Misuse, And Addiction
Educate patients and their families about the risks of abuse, misuse, and addiction of Focalin XR, which can lead to overdose and death, and proper disposal of any unused drug [see WARNINGS AND PRECAUTIONS, Drug Abuse And Dependence, OVERDOSAGE]. Advise patients to store Focalin XR in a safe place, preferably locked, and instruct patients to not give Focalin XR to anyone else.
Risks To Patients With Serious Cardiac Disease
Advise patients that there are potential risks to patients with serious cardiac disease, including sudden death, with Focalin XR use. Instruct patients to contact a healthcare provider immediately if they develop symptoms, such as exertional chest pain, unexplained syncope, or other symptoms suggestive of cardiac disease [see WARNINGS AND PRECAUTIONS].
Increased Blood Pressure And Heart Rate
Instruct patients that Focalin XR can cause elevations of their blood pressure and pulse rate [see WARNINGS AND PRECAUTIONS].
Psychiatric Adverse Reactions
Advise patients that Focalin XR, at recommended doses, can cause psychotic or manic symptoms, even in patients without prior history of psychotic symptoms or mania [see WARNINGS AND PRECAUTIONS].
Priapism
Advise patients of the possibility of painful or prolonged penile erections (priapism). Instruct them to seek immediate medical attention in the event of priapism [see WARNINGS AND PRECAUTIONS].
Circulation Problems In Fingers And Toes (Peripheral Vasculopathy, Including Raynaud’s Phenomenon)
Instruct patients beginning treatment with Focalin XR about the risk of peripheral vasculopathy, including Raynaud’s phenomenon, and associated signs and symptoms: fingers or toes may feel numb, cool, painful, and/or may change color from pale, to blue, to red. Instruct patients to report to their physician any new numbness, pain, skin color change, or sensitivity to temperature in fingers or toes.
Instruct patients to call their physician immediately with any signs of unexplained wounds appearing on fingers or toes while taking Focalin XR. Further clinical evaluation (e.g., rheumatology referral) may be appropriate for certain patients [see WARNINGS AND PRECAUTIONS].
Long-Term Suppression Of Growth In Pediatric Patients
Advise patients that Focalin XR may cause slowing of growth and weight loss [see WARNINGS AND PRECAUTIONS].
Increased Intraocular Pressure (IOP) And Glaucoma
Advise patients that IOP and glaucoma may occur during treatment with Focalin XR [see WARNINGS AND PRECAUTIONS].
Motor And Verbal Tics, And Worsening Of Tourette’s Syndrome
Advise patients that motor and verbal tics and worsening of Tourette’s Syndrome may occur during treatment with Focalin XR. Instruct patients to notify their healthcare provider if emergence of new tics or worsening of tics or Tourette’s syndrome occurs [see WARNINGS AND PRECAUTIONS].
Pregnancy Registry
Advise patients that there is a pregnancy exposure registry that monitors pregnancy outcomes in patients exposed to ADHD medications, including Focalin XR, during pregnancy [see Use In Specific Populations].
Nonclinical Toxicology
Carcinogenesis, Mutagenesis, And Impairment Of Fertility
Carcinogenesis
Lifetime carcinogenicity studies have not been carried out with dexmethylphenidate. In a lifetime carcinogenicity study carried out in B6C3F1 mice, racemic methylphenidate caused an increase in hepatocellular adenomas and, in males only, an increase in hepatoblastomas was seen at a daily dose of approximately 60 mg/kg/day. This dose is approximately 2 times the MRHD of 60 mg/day of racemic methylphenidate given to children on a mg/m² basis. Hepatoblastoma is a relatively rare rodent malignant tumor type. There was no increase in total malignant hepatic tumors. The mouse strain used is sensitive to the development of hepatic tumors, and the significance of these results to humans is unknown.
Racemic methylphenidate did not cause any increase in tumors in a lifetime carcinogenicity study carried out in F344 rats; the highest dose used was approximately 45 mg/kg/day, which is approximately 4 times the MRHD (children) of 60 mg/day of racemic methylphenidate in children on a mg/m² basis.
In a 24-week carcinogenicity study with racemic methylphenidate in the transgenic mouse strain p53+/-, which is sensitive to genotoxic carcinogens, there was no evidence of carcinogenicity. Male and female mice were fed diets containing the same concentrations as in the lifetime carcinogenicity study; the high-dose group was exposed to 60 to74 mg/kg/day of racemic methylphenidate.
Mutagenesis
Dexmethylphenidate was not mutagenic in the in vitro Ames reverse mutation assay, in the in vitro mouse lymphoma cell forward mutation assay, or in the in vivo mouse bone marrow micronucleus test. In an in vitro assay using cultured Chinese Hamster Ovary cells treated with racemic methylphenidate, sister chromatid exchanges and chromosome aberrations were increased, indicative of a weak clastogenic response.
Impairment Of Fertility
No human data on the effect of methylphenidate on fertility are available.
Fertility studies have not been conducted with dexmethylphenidate. Racemic methylphenidate did not impair fertility in male or female mice that were fed diets containing the drug in an 18-week continuous breeding study. The study was conducted at doses of up to 160 mg/kg/day, approximately 10 times the MRHD of 60 mg/day of racemic methylphenidate given to adolescents on a mg/m² basis.
Use In Specific Populations
Pregnancy
Pregnancy Exposure Registry
There is a pregnancy exposure registry that monitors pregnancy outcomes in women exposed to ADHD medications, including Focalin XR, during pregnancy. Healthcare providers are encouraged to register patients by calling the National Pregnancy Registry for ADHD medications at 1-866-961-2388 or visiting https://womensmentalhealth.org/adhdmedications/.
Risk Summary
Dexmethylphenidate is the d-threo enantiomer of racemic methylphenidate. Published studies and postmarketing reports on methylphenidate use during pregnancy have not identified a drug-associated risk of major birth defects, miscarriage or adverse maternal or fetal outcomes. There may be risks to the fetus associated with the use of CNS stimulants during pregnancy (see Clinical Considerations). Embryo-fetal development studies in rats showed delayed fetal skeletal ossification at doses up to 5 times the maximum recommended human dose (MRHD) of 20 mg/day given to adults based on plasma levels. A decrease in pup weight in males was observed in a pre- and post-natal development study with oral administration of methylphenidate to rats throughout pregnancy and lactation at doses 5 times the MRHD of 20 mg/day given to adults based on plasma levels (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 clinically recognized pregnancies is 2% to 4% and 15% to 20%, respectively.
Clinical Considerations
Fetal/Neonatal Adverse Reactions
CNS stimulants, such as Focalin XR, 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
In embryo-fetal development studies conducted in rats and rabbits, dexmethylphenidate was administered orally at doses of up to 20 and 100 mg/kg/day, respectively, during the period of organogenesis. No evidence of malformations was found in either the rat or rabbit study; however, delayed fetal skeletal ossification was observed at the highest dose level in rats. When dexmethylphenidate was administered to rats throughout pregnancy and lactation at doses of up to 20 mg/kg/day, post-weaning body weight gain was decreased in male offspring at the highest dose, but no other effects on postnatal development were observed. At the highest doses tested, plasma levels [area under the curves (AUCs)] of dexmethylphenidate in pregnant rats and rabbits were approximately 5 and 1 times, respectively, those in adults dosed with 20 mg/day. Plasma levels in adults were comparatively similar to plasma levels in adolescents.
Racemic methylphenidate has been shown to cause malformations (increased incidence of fetal spina bifida) in rabbits when given in doses of 200 mg/kg/day throughout organogenesis.
Lactation
Risk Summary
Dexmethylphenidate is the d-threo enantiomer of racemic methylphenidate. 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 Focalin XR and any potential adverse effects on the breastfed infant from Focalin XR or from the underlying maternal condition.
Clinical Considerations
Monitor breastfeeding infants for adverse reactions, such as agitation, insomnia, anorexia, and reduced weight gain.
Pediatric Use
The safety and effectiveness of Focalin XR for the treatment of ADHD have been established in pediatric patients aged 6 to 17 years in two adequate and well-controlled clinical trials [see Clinical Studies].
The safety and effectiveness of Focalin XR in pediatric patients aged less than 6 years have not been established.
The long-term efficacy of Focalin XR in pediatric patients has not been established.
Long Term Suppression Of Growth
Growth should be monitored during treatment with stimulants, including Focalin XR. Pediatric patients who are not growing or gaining weight as expected may need to have their treatment interrupted [see WARNINGS AND PRECAUTIONS].
Juvenile Animal Toxicity Data
Rats treated with racemic 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 6 times the MRHD of 60 mg/day given to children on a mg/m² basis.
In a study conducted in young rats, racemic 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 of racemic methylphenidate 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.
Geriatric Use
Focalin XR has not been studied in the geriatric population.
