Segesterone acetate and ethinyl estradiol combination is used to prevent pregnancy. It is a flexible birth control vaginal system (in the shape of a ring) that contains two types of hormones, segesterone acetate and ethinyl estradiol. It works by stopping a woman's egg from fully developing each month. The egg can no longer accept a sperm and fertilization (pregnancy) is prevented.

No contraceptive method is 100 percent effective. Birth control methods such as having surgery to become sterile or not having sex are more effective than vaginal systems. Discuss your options for birth control with your doctor.

Segesterone acetate and ethinyl estradiol will not prevent HIV infection or other sexually transmitted diseases. It will not help as emergency contraception, such as after unprotected sexual contact.

Segesterone acetate and ethinyl estradiol is available only with your doctor's prescription.
