Etonogestrel and ethinyl estradiol combination is used to prevent pregnancy. It is a flexible birth control vaginal ring that contains two types of hormones, etonogestrel 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 rings. Discuss your options for birth control with your doctor.

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

Ethinyl estradiol and etonogestrel is available only with your doctor's prescription.
