NuvaRing contains ethinyl estradiol and etonogestrel, a combination of female hormones that prevent ovulation (the release of an egg from an ovary). They also cause 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.
NuvaRing is used as contraception to prevent pregnancy.
NuvaRing use can harm an unborn baby or cause birth defects. Do not use ethinyl estradiol and etonogestrel if you are pregnant. Tell your doctor right away if you become pregnant during treatment. Do not use NuvaRing if you are allergic to ethinyl estradiol or etonogestrel, or if you have:
- 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.
Before using NuvaRing, tell your doctor if you have any of the following conditions. You may need a dose adjustment or special tests to safely use NuvaRing.
- high blood pressure, heart disease, congestive heart failure, angina (chest pain), or a history of heart attack;
- high cholesterol or triglycerides;
- kidney disease;
- a history of depression;
- gallbladder disease;
- seizures or epilepsy;
- a history of irregular menstrual cycles, toxic shock syndrome, or easy vaginal irritation;
- prolapsed (dropped) uterus, bladder, or rectum;
- a history of fibrocystic breast disease, lumps, nodules, or an abnormal mammogram;
- severe constipation; or
- migraine headaches.
The hormones in birth control pills can pass into breast milk and may harm a nursing baby. NuvaRing may also slow breast milk production. Do not use if you are breast-feeding a baby.
