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. NuvaRing is not for women with a history of these conditions or any condition that makes your blood more likely to clot. The use of a CHC, like NuvaRing, is associated with increased risks of several serious side effects, including blood clots, stroke, or heart attack.This risk increases with age and the number of cigarettes smoked. 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. Do not use NuvaRing if you smoke cigarettes and are over 35 years old.
