Concomitant Use of Atomoxetine and OROS ® -Methylphenidate in a 10-Year-Old Child Suffering from Attention-Deficit/Hperactivity Disorder with Comorbid Bipolar Disorder and Tourette Syndrome.

Atomoxetine and OROS® methylphenidate were successfully used concomitantly in a 10- year-old boy suffering from attention-deficit/hyperactivity disorder (ADHD) with comorbid bipolar disorder and Tourette syndrome (TS). The child received valproic acid, clonidine, and ziprasidone concurrently. Because possible side effects of pharmacological treatment for one diagnosis may exacerbate a comorbid condition, contingent management strategies, when using polypharmacy, are mandated.
