RAZADYNE ER Extended-Release Capsules

RAZADYNE ER extended-release capsules should be administered once daily in the morning, preferably with food.

The recommended starting dosage of RAZADYNE ER is 8 mg/day. The dosage should be increased to the initial maintenance dose of 16 mg/day after a minimum of 4 weeks. A further increase to 24 mg/day should be attempted after a minimum of 4 weeks at 16 mg/day. Dosage increases should be based upon assessment of clinical benefit and tolerability of the previous dose.

The dosage of RAZADYNE ER shown to be effective in a controlled clinical trial is 16–24 mg/day.

Patients currently being treated with RAZADYNE tablets can convert to RAZADYNE ER (extended-release capsules) by taking their last dose of RAZADYNE tablets in the evening and starting RAZADYNE ER once daily treatment the next morning. Converting from RAZADYNE to RAZADYNE ER should occur at the same total daily dosage.

RAZADYNE Immediate-Release Tablets

The dosage of RAZADYNE tablets shown to be effective in controlled clinical trials is 16–32 mg/day given as twice daily dosing. As the dosage of 32 mg/day is less well tolerated than lower dosages and does not provide increased effectiveness, the recommended dosage range is 16–24 mg/day given twice daily. The dosage of 24 mg/day did not provide a statistically significant greater clinical benefit than 16 mg/day. It is possible, however, that a daily dosage of 24 mg of RAZADYNE might provide additional benefit for some patients.

The recommended starting dosage of RAZADYNE tablets is 4 mg twice a day (8 mg/day). The dosage should be increased to the initial maintenance dosage of 8 mg twice a day (16 mg/day) after a minimum of 4 weeks. A further increase to 12 mg twice a day (24 mg/day) should be attempted after a minimum of 4 weeks at 8 mg twice a day (16 mg/day).

Dosage increases should be based upon assessment of clinical benefit and tolerability of the previous dose.

RAZADYNE tablets should be administered twice a day, preferably with morning and evening meals.

Patients and caregivers should be advised to ensure adequate fluid intake during treatment. If therapy has been interrupted for more than three days, the patient should be restarted at the lowest dosage and the dosage escalated to the current dose.

The abrupt withdrawal of RAZADYNE ER and RAZADYNE in those patients who had been receiving dosages in the effective range was not associated with an increased frequency of adverse events in comparison with those continuing to receive the same dosages of that drug. The beneficial effects of RAZADYNE ER and RAZADYNE are lost, however, when the drug is discontinued.

Dosage in Patients with Hepatic Impairment

In patients with moderate hepatic impairment (Child-Pugh score of 7–9), the dosage should generally not exceed 16 mg/day. The use of RAZADYNE ER and RAZADYNE in patients with severe hepatic impairment (Child-Pugh score of 10–15) is not recommended [see Clinical Pharmacology (12.3)].

Dosage in Patients with Renal Impairment

In patients with creatinine clearance of 9 to 59 mL/min, the dosage should generally not exceed 16 mg/day. In patients with creatinine clearance less than 9 mL/min, the use of RAZADYNE ER and RAZADYNE is not recommended [see Clinical Pharmacology (12.3)].
