Why it is Prescribed
Etonogestrel and ethinyl estradiol vaginal ring is used to prevent pregnancy. Etonogestrel and ethinyl estradiol vaginal ring is in a class of medications called combination hormonal contraceptives (birth control medications). Etonogestrel is a progestin and ethinyl estradiol is an estrogen. Etonogestrel and ethinyl estradiol vaginal ring works by preventing ovulation (the release of an egg from the ovaries). It also changes the lining of the uterus (womb) to prevent pregnancy from developing and changes the mucus at the cervix (opening of the uterus) to prevent sperm (male reproductive cells) from entering. The contraceptive ring is a very effective method of birth control but does not prevent the spread of human immunodeficiency virus [HIV, the virus that causes acquired immunodeficiency syndrome (AIDS)] or other sexually transmitted diseases.

How it Works
Etonogestrel and ethinyl estradiol combination comes as a flexible ring to place in the vagina. It is usually placed in the vagina and left in place for 3 weeks. After 3 weeks, it is removed for a 1-week break; then a new ring is inserted. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Use the contraceptive ring exactly as directed. Never use more than one contraceptive ring at a time and always insert and remove the ring according to the schedule your doctor gives you.
You should always insert and remove the contraceptive ring on the same day of the week and at about the same time of day. Your menstrual period will probably start 2-3 days after you remove the contraceptive ring and may continue through that week. Be sure ...
