Generic Name: ethinyl estradiol and etonogestrel (vaginal ring) (ETH in il es tra DYE ole and et oh noe JES trel)
Brand Names: NuvaRing

What is NuvaRing?

The NuvaRing vaginal ring contains a combination of ethinyl estradiol and etonogestrel. Ethinyl estradiol and etonogestrel are female hormones that prevent ovulation (the release of an egg from an ovary).

The hormones in NuvaRing 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.

The NuvaRing vaginal ring is used as contraception to prevent pregnancy.

How should I use NuvaRing?

Use NuvaRing exactly as prescribed by your doctor. Follow all directions on your prescription label. Do not wear more than one ring at a time. Read all patient information, medication guides, and instruction sheets provided to you. Ask your doctor or pharmacist if you have any questions.

Your doctor will tell you which day to insert the first vaginal ring you use. During the first 7 days, you may need to use back-up birth control (condoms or spermicide, but not a diaphragm or female condom).

The NuvaRing vaginal ring will not prevent pregnancy if you wear it only during intercourse. You must wear the ring around-the-clock for 3 full weeks (21 days).

After 21 days, remove the ring and wait 7 full days before inserting a new ring. Avoid leaving the vaginal ring in place for longer than 3 weeks. Call your doctor if you get off schedule.

The NuvaRing vaginal ring should stay in place during sexual intercourse. You may remove the ring, rinse it with warm water, and reinsert it after intercourse. Do not leave the ring out for longer than 3 hours.

You may have breakthrough bleeding. Tell your doctor if this bleeding continues or is very heavy.

If you need surgery or medical tests or if you will be on bed rest, you may need to stop using NuvaRing for a short time. Talk with your doctor.

Store unused NuvaRing rings at room temperature for up to 4 months. Protect from heat and light. Dispose of a used vaginal ring in the foil pouch it came in and throw it away where children and pets cannot get to it. Do not flush the NuvaRing down a toilet.
