Trazodone and Priapism Risk

Mechanism and Clinical Management

Trazodone's antagonism of alpha2-adrenergic receptors may relax penile vascular and corporal smooth muscle, enhancing arterial inflow, according to the American Urological Association guidelines 1
Urgent urological evaluation is required for any erection lasting >4 hours, with treatment following standard priapism protocols with intracavernosal phenylephrine as initial therapy, as recommended by the American Urological Association 2
Delayed treatment beyond 36 hours is associated with permanent erectile dysfunction with no recovering erectile function, emphasizing the need for immediate intervention, as noted in guidelines from the American Urological Association 2
The use of trazodone is not recommended for erectile dysfunction treatment due to its association with priapism, as stated in guidelines from the American Urological Association 1

Treatment should follow standard priapism protocols, with intracavernosal phenylephrine as initial therapy, to minimize the risk of permanent damage, as recommended by the American Urological Association 3
