Application :

Norethindrone Acetate is used to treat women with abnormal bleeding from the uterus.

Norethindrone Acetate is also used to treat women who have stopped having menstrual periods for several months (amenorrhea) but who are not pregnant or going through menopause.

In addition, Norethindrone Acetate is used to treat a condition (endometriosis) in which tissue that normally lines the inside of the uterus is found outside the uterus in theabdomen/pelvic area, causing painful/irregular periods.

Norethindrone Acetate is like the hormone progesterone that your body makes naturally. This medication works by stopping the normal growth of the uterus lining during the menstrual cycle and signaling hormone changes in the uterus to restore normal menstrual periods.

Description
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.

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 disease, or if you have recently had an incomplete miscarriage or abortion.

You may need to use back-up birth control, such as condoms or a spermicide, when you first start using this medication. Follow your doctor's instructions.

Taking hormones can increase your risk of blood clots, stroke, or heart attack, especially if you smoke and are older than 35.

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.

This medication can cause birth defects. Do not use if you are pregnant. Tell your doctor right away if you become pregnant.
