Urinary Retention Associated With Cariprazine: A Case Report.

Urinary retention is a well-documented adverse effect of antipsychotic medications and is thought to be mediated by anticholinergic, adrenergic, and other neurotransmitter effects. Whereas urinary retention has been reported with typical and some atypical antipsychotics, there have been no reports of urinary retention with the novel antipsychotic cariprazine. We report on a case of urinary retention associated with cariprazine. Possible mechanisms for this adverse effect are discussed.
