Chlorpromazine induced priapism from a single dose: an unusual complication of antipsychotic agent

Abstract

Priapism is considered as an unusual andrological emergency that requires urgent intervention. It is defined as prolonged penile erection (usually painful) for more than 4 hours not related to sexual excitation or stimulation. Several causes have been attributed to cause such condition including the use of psychotropic drugs as chlorpromazine. Only few case reports in literature have recorded priapism as a complication of administration of chlorpromazine, however most of them were due to overdose or prolonged administration for prolonged period or as an interaction with other drugs. Here, in this case report is about a 23 years old male presented to the emergency department with neglected priapism after administration of a single dose of chlorpromazine.
