What is Nuvaring used for?

  • NuvaRing is a birth control medication. NuvaRing is a small flexible ring that releases medications when placed inside a woman’s vagina. NuvaRing contains the female sex hormones progestin and estrogen.

  • It works by releasing a low dose of estrogen and progestin in order to prevent pregnancy.

  • NuvaRing is a birth control ring that is inserted into the vagina once every 4 weeks. 

  • NuvaRing lowers the chances of getting pregnant. However, it does not protect against sexually transmitted infections (STIs) or human immunodeficiency virus (HIV). 

  • You should not use NuvaRing if you are over 35 years old and smoke cigarettes. Smoking can increase the risk of serious heart and blood vessel problems, such as death from heart attack or stroke. 

  • NuvaRing isn’t the best birth control option for women who are breastfeeding because it can lower your milk supply. If you’re breastfeeding, talk to your healthcare provider about other birth control options.

    • 11.7 milligrams (mg) etonogestrel and 2.7 mg ethinyl estradiol

What are common Nuvaring doses?

  • Insert NuvaRing on the first day of menstrual bleeding. Keep it in place for 3 weeks (21 days). After 3 weeks, remove NuvaRing for 1 week (7 days). During this week, you will usually have a menstrual period.

Common Nuvaring prescriptions

  • NuvaRing
    0.12-0.015mg/24hr ring

How to take Nuvaring

  • Store this medicine at room temperature, away from heat and direct light for up to 4 months. Place the used vaginal ring in the re-sealable foil pouch and throw it in the trash. Do not flush the ring down the toilet.

  • Once the ring is in place, you should not be able to feel it. If you feel uncomfortable, the ring may not be inserted far enough. Gently push the ring farther into your vagina. If you feel pain, talk to your doctor.

  • In some cases, you may need to use a second form of birth control during the first 7 days to avoid pregnancy. Check with your doctor about if you should use a second form of birth control, such as a barrier method. Do not use a diaphragm, because the ring may affect how the diaphragm fits.

  • Read and follow the patient instructions that come with this medicine. Talk to your doctor or pharmacist if you have any questions.

  • Check for the presence of the ring inside your vagina regularly (including before and after having sex).

  • This medicine is in a ring that is put into your vagina. Your doctor or nurse will show you how to put in the ring. The ring should be left in place for 3 weeks. It will then be removed and another one will be inserted 1 week later. During the week without the ring, you will usually have your menstrual period.

What to do if you miss a dose of Nuvaring

  • If NuvaRing has slipped out and it has been out for less than 3 hours, rinse it in cool or lukewarm water and reinsert it. You should still be protected from pregnancy.

  • If NuvaRing has been out for more than 3 hours, insert a new ring. You must use an extra method of birth control until the NuvaRing has been in place for 7 days in a row. Do not use a diaphragm.

  • If you leave the vaginal ring in place for more than 4 weeks, you may not be protected from pregnancy. Make sure that you are not pregnant before you insert a new ring. You must use an additional form of birth control (not a diaphragm) until the new ring has been in place for 7 days in a row.

  • If you forget to insert a new ring after the ring-free week, call your doctor for instructions.

Nuvaring contraindications

  • This medicine is not right for everyone. Do not use it if you had an allergic reaction to etonogestrel or ethinyl estradiol, if you are pregnant, if you take certain drugs for Hepatitis C, or if you have vaginal bleeding that has not been checked by a doctor. Do not use it if you have liver disease or tumors, breast cancer, problems with blood clots, or certain heart problems.
