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.
Tell your health care provider about all medicines and herbal products you take, including prescription and over-the-counter medicines, vitamins and herbal supplements.
Some medicines and herbal products may make hormonal birth control less effective, including, but not limited to:
Use an additional birth control method (such as a male condom with spermicide) when you take medicines that may make NuvaRing (etonogestrel/ethinyl estradiol vaginal ring) less effective. Continue back-up birth control for 28 days after stopping the medicine to help prevent you from becoming pregnant.
Some medicines and grapefruit juice may increase the level of ethinyl estradiol in your blood if used together, including:
Hormonal birth control methods may interact with lamotrigine, a medicine used for seizures. This may increase the risk of seizures, so your health care provider may need to adjust your dose of lamotrigine.
Women on thyroid replacement therapy may need increased doses of thyroid hormone.
Ask your health care provider if you are not sure if you take any of the medicines listed above. Know the medicines you take. Keep a list of them to show your health care provider and pharmacist when you get a new medicine.
