Treatment of acne vulgaris with cyproterone acetate and ethinyl estradiol

The results obtained with low-dosage treatment with 2 mg cyproterone acetate and 0.05 mg ethinyl estradiol in 10 women with moderate to severe acne are reported. Eight of these patients showed a very good response, one a moderate response, and one showed no improvement after 3 months. In four patients the administration of antibiotics could be discontinued, and in most of the other patients the dose could be reduced. Three patients discontinued this treatment, two because of side effects and one because of lack of improvement.
