Progestogen with antiandrogenic properties used in the treatment of hypersexuality, prostate cancer, transsexuality (transsexual women) and, together with ethinylestradiol, in hirsutism, acne and hyperandrogenism, polycystic ovary syndrome and alopecia in women.
At a daily dose of 50 mg, it is excreted in breast milk in very small amounts: RID < 1% (Stoppelli 1980), and no antiandrogenic effects have been reported in infants.
The small amount (2 mg) found in contraceptive tablets in which it is combined with ethinylestradiol or estradiol would have a very low risk and would be compatible with breastfeeding.
