title: Increased Frequency of Encopresis in a Child Diagnosed With Attention Deficit/Hyperactivity Disorder and Encopresis After Atomoxetine Use: A Case Report.
abstract: Attention deficit hyperactivity disorder (ADHD) is among the most frequently reported coexisting psychiatric conditions in children with encopresis. Some case reports state that atomoxetine-a selective presynaptic norepinephrine reuptake inhibitor-approved for treatment of ADHD is also effective in the treatment of coexisting encopresis. Contrasting those reports, here we present a case diagnosed with ADHD and secondary encopresis without constipation whose encopretic symptoms increased after atomoxetine treatment and discuss possible mechanisms.
