What is ethinyl estradiol and etonogestrel (NuvaRing)?
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 may also be used for other purposes not listed in this medication guide.

What is the most important information I should know about ethinyl estradiol and etonogestrel (NuvaRing)?
Do not use this medication if you have any of the following conditions: a history of stroke or blood clot, circulation problems (especially if caused by diabetes), a hormone-related cancer such as breast or uterine cancer, abnormal vaginal bleeding, liver disease or liver cancer, severe high blood pressure, severe migraine headaches, a heart valve disorder, or a history of jaundice caused by birth control pills.
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.
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.
