This medication can cause birth defects in an unborn baby. Do not use
if you are pregnant. Use an effective form of birth control, and tell your doctor if you
become pregnant during treatment.
Do not use this medication if you have any of the following conditions: a history of
stroke or blood clot, circulation problems, breast cancer, abnormal vaginal bleeding, liver

Norethindrone does not protect you from sexually transmitted diseases--including HIV
and AIDS. Using a condom is the only way to help protect yourself from these diseases.
What is norethindrone?
Norethindrone is a form of progesterone, a female hormone. Norethindrone prevents
ovulation (the release of an egg from an ovary). This medication also causes changes in your
cervical mucus and uterine lining, making it harder for sperm to reach the uterus and harder for a
fertilized egg to attach to the uterus.
Norethindrone is used for birth control (contraception) to prevent pregnancy.
Norethindrone is also used to treat menstrual disorders, endometriosis, or abnormal vaginal
bleeding caused by a hormone imbalance.
Norethindrone may also be used for other purposes not listed in this medication guide.
