Gestrinone, sold under the brand names Dimetrose and Nemestran among others, is a medication which is used in the treatment of endometriosis.[3][4] It has also been used to treat other conditions such as uterine fibroids and heavy menstrual bleeding and has been investigated as a method of birth control.[5][6][1] Gestrinone is used alone and is not formulated in combination with other medications.[7] It is taken by mouth or in through the vagina.[1][8]

Side effects of gestrinone include menstrual abnormalities, estrogen deficiency, and symptoms of masculinization like acne, seborrhea, breast shrinkage, increased hair growth, and scalp hair loss, among others.[1][8][9][10] Gestrinone has a complex mechanism of action, and is characterized as a mixed progestogen and antiprogestogen, a weak androgen and anabolic steroid, a weak antigonadotropin, a weak steroidogenesis inhibitor, and a functional antiestrogen.[11][1][12][13]

Gestrinone was introduced for medical use in 1986.[14] It has been used extensively in Europe but appears to remains marketed only in a few countries throughout the world.[10][15][7] The medication is not available in the United States.[16] Due to its anabolic effects, the use of gestrinone in competition has been banned by the International Olympic Committee.[17]
