Ethinylestradiol/cyproterone acetate (EE/CPA), also known as co-cyprindiol and sold under the brand names Diane and Diane-35 among others, is a combination of ethinylestradiol (EE), an estrogen, and cyproterone acetate (CPA), a progestin and antiandrogen, which is used as a birth control pill to prevent pregnancy in women. It is also used to treat androgen-dependent conditions in women such as acne, seborrhea, excessive facial/body hair growth, scalp hair loss, and high androgen levels associated with ovaries with cysts. The medication is taken by mouth once daily for 21 days, followed by a 7-day free interval.
