ABSTRACT
A 29-year-old man developed priapism following the (re)administration of zuclopentixol. In the previous days, a significant amount of alcohol was consumed, presumably in combination with amphetamine and cannabis. Priapism is a rare but serious side effect of various psychoactive medications and recreational drugs, leading to permanent loss of erectile function if not treated in time. In this case the side effect was discovered in a late stage, at which curative treatment was no longer viable. A clear guideline for choosing an alternative antipsychotic agent is currently lacking, but an antipsychotic with low alfa-adrenergic affinity seems preferable. To prevent erectile disfunction following priapism, awareness of its severity is essential, for both doctor and patient.
