Add-on Milnacipran Boosts Methylphenidate Response in an Adolescent With Attention-Deficit/Hyperactivity Disorder With Comorbid Anxiety and Enuresis

Risperidone-associated enuresis—a case report

Background

Risperidone has been reported to be effective in treating both the positive and negative symptoms of schizophrenia, aggression, and behavioral disorders. While the metabolic side effect profile of this medication has been broadly studied, studies related to this medication’s bladder effects are relatively rare. We present a case of risperidone-induced enuresis in an adult male with schizophrenia that resolved upon discontinuation of the offending medication.

Case presentation

We describe a case of a 32-year-old man with a primary psychotic disorder who developed debilitating enuresis secondary to taking risperidone. Enuresis resolved upon switching to Seroquel.

Conclusion

Enuresis secondary to risperidone is not commonly discussed prior to initiation by the treating psychiatrist however can be debilitating. Discussing this potential side effect is critical to informed decision making on the patient’s part.
