Each blister pack contains 21 tablets, with each tablet consisting of Cyproterone acetate (2 mg) and Ethinylestradiol (0.035 mg). The recommended treatment cycle involves taking the tablet for 21 consecutive days, followed by a 7-day interval without medication.

Cyproterone is a steroid with antiandrogenic, progestogenic, and antigonadotropic properties. It works by blocking androgen receptors and reducing androgen production. When combined with Ethinylestradiol, it prevents ovulation and also increases sex hormone-binding globulin (SHBG), leading to reduced free androgens in the bloodstream.

First Treatment Course: Take one tablet daily for 21 consecutive days, starting on the first day of menstruation. This should be followed by a 7-day break, during which withdrawal bleeding may occur.

Subsequent Courses: The next cycle starts exactly seven days after the last tablet, even if withdrawal bleeding is still ongoing. Treatment should be continued for several months, with improvements typically seen after three months.

Missed Dose: If a tablet is missed, it can be taken within 12 hours. If more than 12 hours have passed, the missed tablet should be skipped, and the next tablet should be taken at the usual time. A backup contraceptive method is necessary for the rest of the cycle.
