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.
Remember, keep this and all other medicines out of the reach of children, never share
your medicines with others, and use this medication only for the indication prescribed.
