Cigarette smoking increases the risk of serious heart and blood vessel side effects from birth control pill use.

Norethindrone/Ethinyl Estradiol is used for:

Prevention of pregnancy. It may also be used to regulate the menstrual cycle. It does NOT protect against HIV infection (AIDS) and other sexually transmitted diseases. It may also be used for other conditions as determined by your doctor.

Norethindrone/Ethinyl Estradiol is a combination of 2 female sex hormones, estrogen and progestin. Norethindrone/Ethinyl Estradiol works by preventing the ovaries from releasing eggs.
