Once-daily OROS methylphenidate is safe and well tolerated in adolescents with attention-deficit/hyperactivity disorder

This 8-week, open-label extension of a double-blind study reports on safety data for 171 adolescents with attention-deficit/hyperactivity disorder (ADHD) who received once-daily OROS methylphenidate (MPH) (18-72 mg/day). Headache, anorexia, and insomnia were the most frequently reported treatment-related adverse events. The incidence of adverse events was not related to dose. OROS MPH was safe and well tolerated at doses up to 72 mg/day.
