Availability

Capsules: 5 mg, 10 mg, 20 mg

Tablets (extended-release): 10 mg, 20 mg, 30 mg, 60 mg, 90 mg

Patient may be switched to extended-release at nearest equivalent of immediate-release daily dosage (for instance, 30-mg immediate-release dose may be switched to 90-mg extended-release dose). Total extended-release dosage should not exceed 90 mg/day.
