NuvaRing (vaginal ring)Pronunciation
Generic Name: ethinyl estradiol and etonogestrel (vaginal ring) (ETH in il es tra DYE ole and et oh noe JES trel)
Brand Name: NuvaRing
What is ethinyl estradiol and etonogestrel?
The ethinyl estradiol and etonogestrel vaginal ring contains female hormones that prevent ovulation (the release of an egg from an ovary). This medicine 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 vaginal ring is used as contraception to prevent pregnancy.
Ethinyl estradiol and etonogestrel may also be used for purposes not listed in this medication guide.

What should I discuss with my healthcare provider before using this medicine?
Using this medicine can increase your risk of blood clots, stroke, or heart attack. You are even more at risk if you have high blood pressure, diabetes, high cholesterol, or if you are overweight. Your risk of stroke or blood clot is highest during your first year of using the vaginal ring. Your risk is also high when you insert a new ring after not wearing one for 4 weeks or longer.
Smoking can greatly increase your risk of blood clots, stroke, or heart attack. Your risk increases the older you are and the more you smoke. You should not use the vaginal ring if you smoke and are older than 35 years of age.
This medicine can cause birth defects. Do not use if you are pregnant. Tell your doctor right away if you become pregnant, or if you miss two menstrual periods in a row. If you have recently had a baby, wait at least 4 weeks before using an ethinyl estradiol and etonogestrel vaginal ring.

How should I use this medicine?
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).
The 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).
Remove the ring on the same day of the week it was inserted, at about the same time of day. 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 ring should stay in place during sexual intercourse. If the ring is bothersome, you may remove it, 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 this medicine for a short time. Any doctor or surgeon who treats you should know that you are using the vaginal ring.
Store unused vaginal rings for up to 4 months at room temperature. Protect from heat and light. To dispose of a used vaginal ring, place it in the foil pouch it came in and throw it away where children and pets cannot get to it. Do not flush the ring down a toilet.
What happens if I miss a dose?
If a ring falls out during the 3-week wearing time, rinse it with warm water and reinsert it. If the ring is lost or broken, insert a new ring as soon as possible and stay on the same schedule you started. Do not leave a ring out for longer than 3 hours.
During week 1 or 2: If a ring has been out of the vagina for more than 3 hours, you may not be protected from pregnancy.
During week 3: If a ring has been out of the vagina for more than 3 hours, throw it away. Insert a new ring and start a new 3-week cycle. If the removed ring had been in place for at least 1 week, you may wait another 7 days before you insert a new ring.
Always use back-up birth control until a new or replaced ring has been in place for 7 days in a row.
What happens if I overdose?
Seek emergency medical attention or call the Poison Help line at 1-800-222-1222. Overdose symptoms may include nausea, vomiting, and vaginal bleeding.
What should I avoid while using this medicine?
Do not smoke while using the vaginal ring, especially if you are older than 35 years of age.
