The side effects of cyproterone acetate (CPA), a steroidal antiandrogen and progestin, including its frequent and rare side effects, have been studied and characterized.It is generally well-tolerated and has a mild side-effect profile, regardless of dosage, when it used as a progestin or antiandrogen in combination with an estrogen such as ethinylestradiol or estradiol valerate in women.

Cyproterone was studied as a treatment for precocious puberty by Bierich (1970, 1971), but no significant improvement was observed. [22] In men, 100 mg/day cyproterone proved to be rather ineffective in treating acne, which was hypothesized to be related to its progonadotropic effects in males and counteraction of its antiandrogen activity.
