Warnings/Precautions

Potential for Abuse and Dependence 

  • High potential for abuse and dependence.

  • Assess the risk of abuse prior to prescribing and monitor during therapy.

Serious Cardiovascular Reactions 

  • Sudden death, stroke, and myocardial infarction have been reported in adults receiving CNS stimulants. Sudden death has been reported in pediatric patients with structural cardiac abnormalities and other serious heart problems receiving CNS stimulants.

  • Avoid use in patients with known structural cardiac abnormalities, cardiomyopathy, serious heart rhythm abnormalities, coronary artery disease, and other serious heart problems.

  • Evaluate further if exertional chest pain, unexplained syncope, or arrhythmias develop during treatment.

Blood Pressure and Heart Rate Increases

  • Monitor all patients for potential tachycardia and hypertension.

Psychiatric Adverse Reactions

  • Exacerbation of pre-existing psychosis: May exacerbate symptoms of behavior disturbance and thought disorders in patients with pre-existing psychotic behavior.

  • Induction of a manic episode in patients with bipolar disorder: May induce a mixed/manic episode in patients with bipolar disorder. Screen for risk factors for developing a manic episode prior to treatment (eg, comorbid or history of depressive symptoms or a family history of suicide, bipolar disorder, and depression).

  • New psychotic or manic symptoms: May cause psychotic or manic symptoms in patients without a history of psychotic illness or mania. Consider discontinuing if symptoms occur.

Priapism

  • Prolonged and painful erections, sometimes requiring surgical intervention, have been reported.

  • Priapism has not been reported during drug initiation but developed after some time on the drug.

  • Seek immediate medical attention if priapism occurs.

Peripheral Vasculopathy, including Raynaud’s Phenomenon

  • Signs and symptoms are usually intermittent and mild; very rare sequelae include digital ulceration and/or soft tissue breakdown.

  • These signs and symptoms generally improve after reduction in dose or discontinuation.

  • Observe carefully for digital changes during treatment. Evaluate further (eg, rheumatology referral) for certain patients.

Long-Term Suppression of Growth 

  • In pediatric patients, closely monitor growth (weight and height).

  • May need to interrupt treatment in patients who are not growing or gaining height or weight as expected.

Pregnancy Considerations

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 visit https://womensmentalhealth.org/adhd-medications/.

Risk Summary

  • Use in pregnant women have not identified a drug-associated risk for major birth defects, miscarriage, or adverse maternal or fetal outcomes. 

  • The estimated background risk of major birth defects and miscarriage is unknown.

Clinical Considerations

  • Fetal/Neonatal Adverse Reactions: May cause vasoconstriction and may decrease placental perfusion. No fetal and/or neonatal adverse reactions have been reported, but premature delivery and low birth weight infants have been reported in amphetamine-dependent mothers. 

Nursing Mother Considerations

Risk Summary  

  • Consider the developmental and health benefits of breastfeeding 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 Considerations

  • The safety and efficacy of Focalin XR in pediatric patients 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: Monitor growth during treatment with stimulants, including Focalin XR. May need to interrupt treatment in pediatric patients who are not growing or gaining weight as expected.

Geriatric Considerations

Focalin XR has not been studied in the geriatric population.

Focalin Xr Clinical Trials

Clinical Trials

Pediatric PatientsStudy 1

The efficacy and safety of Focalin XR was established in a randomized, double-blind, placebo-controlled, parallel-group study in 103 pediatric patients aged 6 to 17 who met DSM-IV criteria for ADHD inattentive, hyperactive-impulsive or combined inattentive/hyperactive-impulsive subtypes. 

Patients were randomly assigned to receive either a flexible-dose of Focalin XR (5 to 30mg/day) or placebo once daily for 7 weeks. The primary efficacy outcome measure was the mean change from baseline to endpoint using the DSM-IV total subscale score of the Conners ADHD/DSM-IV Scales for teachers (CADS-T), which includes the ADHD Index and the DSM-IV total subscale.

Results showed that treatment with Focalin XR achieved a statsticalliy significant treatment effect for the CADS-T total scores compared with placebo (placebo-subtracted difference, 10.64 [95% CI, 5.38-15.91]).

 

Pediatric Patients Studies 2 and 3

In the 2 crossover studies (Studies 2 and 3), pediatric patients aged 6 to 12 years received Focalin XR 20mg or placebo. Findings showed treatment with Focalin XR achieved statistically significant treatment effect compared with placebo according to the Swanson, Kotkin, Agler, M-Flynn & Pelham (SKAMP) rating scale total scores at all-time points after dosing in each study (0.5, 1, 3, 4, 5, 7, 9, 10, 11, and 12 hours in Study 2 and 1, 2, 4, 6, 8, 9, 10, 11, and 12 hours in the study 3). 

In an additional study, the treatment effect of Focalin XR 20mg was seen 0.5 hours after administration in patients aged 6 to 12 years with ADHD.

 

Adult Patients - Study 4

The efficacy and safety of Focalin XR was established in a randomized, double-blind, placebo-controlled, parallel-group study in 221 adult patients aged 18 to 60 who met DSM-IV criteria for ADHD inattentive, hyperactive-impulsive or combined inattentive/hyperactive-impulsive subtypes. 

Patients were randomly assigned to receive either a flexible-dose of Focalin XR (20, 30, or 40mg/day) or placebo once daily for 5 weeks. The primary efficacy outcome measure was the mean change from baseline to endpoint using the investigator-administered DSM-IV Attention-Deficit/Hyperactivity Disorder Rating Scale (DSM-IV ADHD RS).

Results showed that all 3 Focalin XR doses achieved a statistically significant treatment effect compared with placebo.

  • Focalin XR 20mg/day: Placebo-subtracted difference, 5.71 (95% CI, 1.64-9.78).

  • Focalin XR 30mg/day: Placebo-subtracted difference, 5.31 (95% CI, 1.18-9.44).

  • Focalin XR 40mg/day: Placebo-subtracted difference, 8.96 (95% CI, 4.83-13.08).
