Patients with attention deficit and hyperactivity disorder (ADHD) are at increased risk for Tourette\'s Disorder and other tic disorders. The cornerstone treatment for ADHD include the psychostimulants, such as methylphenidate. It is known that, psychostimulant use can increase existing tics or cause new tics. The selective norepinephrine reuptake inhibitor, atomoxetine, has been proposed to be an alternative medication for patients with ADHD and a comorbid tic disorder. However, there are case studies in the literature describing onset or increase of tics following treatment with atomoxetine. In this report, we discuss a clinical case that developed motor tics during atomoxetine treatment .
