You may need to use back-up birth control, such as condoms or a spermicide, when you first start using this medication. Avoid using a diaphragm with the ethinyl estradiol and etonogestrel vaginal ring. Follow your doctor's instructions.
Taking hormones can increase your risk of blood clots, stroke, or heart attack, especially if you smoke and are older than 35. The ethinyl estradiol and etonogestrel vaginal ring will not prevent pregnancy if you wear it only during intercourse. You must wear the ring for 3 full weeks, followed by 1 full week without a ring. The timing of ring insertion and removal is very important for this medicine to be effective as a form of birth control.Some drugs can make ethinyl estradiol and etonogestrel less effective, which may result in pregnancy. Tell your doctor about all the prescription and over-the-counter medications you use, including vitamins, minerals and herbal products. Do not start using a new medication without telling your doctor.
Ethinyl estradiol and etonogestrel is a combination of female hormones that prevent ovulation (the release of an egg from an ovary). This medication also causes changes in your cervical mucus and uterine lining, making it harder for sperm to reach the uterus and harder for a fertilized egg to attach to the uterus.
Ethinyl estradiol and etonogestrel is used as contraception to prevent pregnancy.
