Attention-deficit/hyperactivity disorder (ADHD) is a chronic condition marked by persistent inattention, hyperactivity, and sometimes impulsivity, which begins in childhood and often lasts into adulthood. Here, we report a patient with ADHD and specific learning disorder (SLD) who had a mydriasis following atomoxetine treatment. The temporal relationship between the time of atomoxetine administration and development of mydriasis in the absence of an identifiable medical condition or confounding medications and the fact that there was no occurrence after atomoxetine discontinuation suggests that atomoxetine was responsible for mydriasis. Although mydriasis is a rare side effect, clinicians should be aware that atomoxetine may cause mydriasis and inform the patients about these potential side effects when prescribing.
