Priapism following ingestion of papaverine tablets

A case of priapism following oral intake of papaverine hydrochloride (300 mg) is reported. The priapism persisted after coitus. It resisted conservative treatment, but responded to aspiration of the corpora cavernosa and irrigation with phenylephrine solution. We found no earlier report of priapism induced by oral papaverine. The possible therapeutic role of oral papaverine in impotence merits study.
