Used primarily in hormonal contraception and management of endometriosis. It works by suppressing ovulation, altering the endometrium to prevent implantation, and reducing the growth of endometrial tissue outside the uterus. Commonly found in oral contraceptive pills, especially those designed for women who may not tolerate estrogen, as it is often used in progestin-only or combined formulations. Its anti-androgenic properties also make it suitable for women with acne or other androgen-related conditions. Due to its favorable safety profile and efficacy, it is widely prescribed for long-term management of chronic gynecological disorders.
