Flutamide, a pure antagonist of the androgen receptor, is effective in treating acne in women. It appears to reduce acne symptoms by 80 to 90% even at low doses, with several studies showing complete acne clearance. In one study, flutamide decreased acne scores by 80% within three months, whereas spironolactone decreased symptoms by only 40% in the same period. In a large long-term study, 97% of women reported satisfaction with the control of their acne with flutamide. Although effective, flutamide has a risk of serious liver toxicity, and cases of death in women taking even low doses of the medication to treat androgen-dependent skin and hair conditions have occurred. As such, the use of flutamide for acne has become increasingly limited, and it has been argued that continued use of flutamide for such purposes is unethical. Bicalutamide, a pure androgen receptor antagonist with the same mechanism as flutamide and with comparable or superior antiandrogenic efficacy but with a far lower risk of liver toxicity, is an alternative option to flutamide in the treatment of androgen-dependent skin and hair conditions in women.
