Abstract

Doxazosin is an adrenergic alpha-1 receptor antagonist used to treat lower urinary tract symptoms that are common in prostatic hyperplasia. To our knowledge, few cases of gynecomastia and mastodynia, as a complication of adrenergic alpha-1 receptor antagonist, have been reported to date; no cases have been reported in Korea. We describe a case involving a 78-year-old man treated for prostatic hyperplasia with 13 months of doxazosin. He complained about unilateral gynecomstia and mastodynia. Five months after the discontinuation of doxazosin, the gynecomastia was significantly improved. This is the first reported case of gynecomastia and mastodynia associated with doxazosin use in Korea.
