Norethindrone acetate in the medical management of adenomyosis.

The role of norethindrone acetate (NA) in the management of adenomyosis was evaluated with a retrospective chart review of 28 premenopausal women between 27-49 years of age presenting with moderate to severe pelvic pain and bleeding. Bleeding and dysmenorrhea scores were analyzed using paired T-tests. There was significant improvement of both dysmenorrhea and bleeding after treatment. Age showed no correlation with dysmenorrhea or bleeding. Low dose NA could be considered an effective, well-tolerated and inexpensive medical alternative to surgery for treating symptomatic adenomyosis. Large multicentric studies may help validate our findings.
