Possible Risks and Side Effects of NuvaRing® (etonogestrel/ethinyl estradiol vaginal ring)

Possible Risks and Side Effects for NuvaRing

NuvaRing may cause serious side effects, including: NuvaRing may cause serious side effects, including: Blood clots. Like pregnancy, combination hormonal birth control methods increase the risk of serious blood clots (see graph below), especially in women who have other risk factors, such as smoking, obesity, or age greater than 35. This increased risk is highest when you first start using a combination hormonal birth control method or when you restart the same or different combination hormonal birth control method after not using it for a month or more. Talk with your health care provider about your risk of getting a blood clot before using NuvaRing or before deciding which type of birth control is right for you.

In some studies of women who used NuvaRing, the risk of getting a blood clot was similar to the risk in women who used combination birth control pills.

Other studies have reported that the risk of blood clots was higher for women who use combination birth control pills containing desogestrel (a progestin similar to the progestin in NuvaRing) than for women who use combination birth control pills that do not contain desogestrel.

It is possible to die or be permanently disabled from a problem caused by a blood clot, such as heart attack or stroke. Some examples of serious blood clots are blood clots in the:

  • Legs (deep vein thrombosis)
  • Lungs (pulmonary embolus)
  • Eyes (loss of eyesight)
  • Heart (heart attack)
  • Brain (stroke)

To put the risk of developing a blood clot into perspective: If 10,000 women who are not pregnant and do not use hormonal birth control are followed for one year, between 1 and 5 of these women will develop a blood clot. The figure below shows the likelihood of developing a serious blood clot for women who are not pregnant and do not use hormonal birth control, for women who use hormonal birth control, for pregnant women, and for women in the first 12 weeks after delivering a baby.

*CHC = combination hormonal contraception **Pregnancy data based on actual duration of pregnancy in the reference studies. Based on a model assumption that pregnancy duration is nine months, the rate is 7 to 27 per 10,000 woman-years.

Important Safety Information
Do not use NuvaRing if you smoke cigarettes and are over age 35. Smoking increases your risk of serious heart and blood vessel problems from combination hormonal contraceptives (CHCs) including heart attack, blood clots, or stroke which can be fatal. This risk increases with age and the number of cigarettes smoked.
  • The use of a CHC, like NuvaRing, is associated with increased risks of several serious side effects, including blood clots, stroke, or heart attack. NuvaRing is not for women with a history of these conditions or any condition that makes your blood more likely to clot. The risk of getting blood clots may be greater with the type of progestin in NuvaRing than with some other progestins in certain low-dose birth control pills. The risk of blood clots is highest when you first start using CHCs and when you restart the same or different CHC after not using it for a month or more.  
  • NuvaRing is also not for women with high blood pressure that medicine can’t control; diabetes with kidney, eye, nerve, or blood vessel damage; certain kinds of severe migraine headaches; liver disease or liver tumors; take any Hepatitis C drug combination containing ombitasvir/paritaprevir/ritonavir, with or without dasabuvir, as this may increase levels of the liver enzyme “alanine aminotransferase” (ALT) in the blood; unexplained vaginal bleeding; breast cancer or any cancer that is sensitive to female hormones; or if you are or may be pregnant.
  • NuvaRing does not protect against HIV infection (AIDS) and other sexually transmitted infections.
