Tadalafil-associated priapism
Abstract
A healthy 46-year-old man presented to the Emergency Department with a 36-hour history of persistent, painful erection after taking the cyclic guanylyl monophosphate-specific phosphodiesterase 5 inhibitor tadalafil. He had no other identified contributing factors for priapism. After confirmation of ischemic priapism and failure of bedside management in the Emergency Department, the patient underwent operative caverno-spongiosal shunting. Postoperatively, the erection initially rebounded but gradually receded with manual compression over 48 hours. At outpatient follow-up, the patient remained flaccid without erections. To our knowledge, this is the first report of tadalafil-associated priapism.
How strong is the evidence?
Evidence Hub reads this as a case report, done in people. Its evidence level is 5 of 5 (Very low · case / narrative / animal / in vitro / in silico). Case reports, narrative reviews, and animal, cell or computer-model studies give the weakest evidence for human health.
