Low-Dose Aripiprazole-Induced Nocturnal Enuresis in a 9-Year-Old Boy: A Case Report and the Possible Underlying Mechanism.

Aripiprazole is an atypical antipsychotic commonly used in the treatment of psychiatric disorders, such as schizophrenia, bipolar disorder, and irritability associated with autism spectrum disorder. Common adverse effects associated with aripiprazole usage in children and adolescents are nausea, vomiting, extrapyramidal adverse effects, akathisia, sedation, tremor, and increased appetite. Enuresis is one of the least expected adverse effects during aripiprazole use. The pathophysiology of aripiprazole-induced enuresis has not been fully clarified. To our knowledge, our report presents enuresis related to aripiprazole use at the lowest dose in the literature. In this report, we present the case of a 9-year-old boy who developed nocturnal enuresis after the beginning of low-dose aripiprazole treatment.
