Norethindrone Introduction

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.

How should I take norethindrone?

Take this medication exactly as it was prescribed for you. Do not take the medication in larger amounts, or take it for longer than recommended by your doctor. Follow the directions on your prescription label.

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.

If you need to have any type of medical tests or surgery, or if you will be on bed rest, you may need to stop using this medication for a short time. Any doctor or surgeon who treats you should know that you are using norethindrone.

Your doctor will need to see you on a regular basis while you are using this medication. Do not miss any appointments.

Store this medication at room temperature away from moisture and heat.
