Methamphetamine and fluoxetine treatment of a child with attention-deficit hyperactivity disorder and obsessive-compulsive disorder.

ABSTRACT An 11-year-old child with obsessive-compulsive disorder, major depression, and attentiondeficit hyperactivity disorder was successfully treated with a combination of fluoxetine (mean 30 mg daily) and methamphetamine (sustained release 10 mg daily). Methamphetamine was selected because of the desirability of avoiding stimulants whose commercial formulations contain food dyes (this child appeared sensitive to tartrazine in dextroamphetamine and other agents), whose effects on hepatic metabolism were minimal (unlike methylphenidate) and whose mechanism of action is reliably rapid (unlike pemoline). Although methamphetamine carries the stigma of an abusable drug and has been implicated in neurotoxicity in animals when used at extremely high doses, methamphetamine may have certain advantages over other psychostimulants in some clinical situations. The combined use of fluoxetine and methamphetamine did not appear to be associated with significant adverse effects.
