Tourette's syndrome: are stimulants safe?

Abstract

Clinicians commonly encounter children with comorbid attention deficit hyperactivity disorder (ADHD) and the tic disorder Tourette's syndrome. The pharmacologic treatment of children with this particular combination of conditions has been problematic because of long-standing warnings against using psychostimulants due to concerns about worsening tics. The basis for these warnings was anecdotal clinical observations. A recent group of placebo-controlled, double-blinded clinical trials have consistently shown that certain stimulants, particularly methylphenidate and dextroamphetamine, are effective, well tolerated, and safe when administered to treat ADHD in children with tics. Methylphenidate appears to be the best-tolerated stimulant compound, with tics often lessening during treatment.
