A danazol-loaded intrauterine device decreases dysmenorrhea, pelvic pain, and dyspareunia associated with endometriosis

Abstract

A danazol-loaded intrauterine device (IUD) containing 300-400 mg of danazol was inserted for 6 months in a group of women (n = 18) (median age 36.6 years; age range: 30 to 46 years) with a histologic diagnosis of endometriosis, referred for recurrent pelvic pain. Dysmenorrhea, dyspareunia, and pelvic pain significantly decreased after the first month, with a persistent effect during the 6 months of IUD insertion. These results show that a danazol-loaded IUD is an effective conservative therapy for patients with endometriosis-related pelvic pain.
