What is norgestrel?

Norgestrel is used by women as a way to prevent pregnancy.

Norgestrel should not be used as emergency birth control (morning after pill) and will not protect you from sexually transmitted diseases including HIV and AIDS.

Norgestrel may also be used for other reasons that are not mentioned in this medication guide.

This section was rewritten for readability and reviewed for meaning.

How should I take norgestrel?

Use exactly as directed on the label, or as prescribed by your doctor. Read and carefully follow the instruction guide provided with the medicine.

Take the medicine at the same time each day.

Do not use norgestrel as an emergency contraceptive (morning after pill) or if you are already pregnant. Norgestrel will not prevent a pregnancy when used after unprotected sex and this medicine will not terminate a pregnancy.

If you are switching from another oral contraceptive, vaginal ring, or patch, start taking norgestrel the day after you stop the other method. Follow your doctor's dosing instructions very carefully.

Make sure you use a barrier form of birth control (condom or diaphragm with spermicide) for the first 2 days (48 hours) when you first start taking norgestrel or if you vomit or have severe diarrhea within 4 hours of taking norgestrel.

Do not stop the medicine without your doctor's advice.

You may have changes in your menstrual period, or your period may stop while taking this medicine. Call your doctor if you have unusual menstrual symptoms, abnormal bleeding, miss your period for 2 months, or you think you may be pregnant.

You may need to take a pregnancy test if you miss any doses or your menstrual period is late.

Your doctor should check your progress on a regular basis. Continue to have regular cervical (Pap smears) and mammograms while taking norgestrel.

Do not keep or flush unused medicine down the toilet. Ask your pharmacist about a drug take-back program.

Store at room temperature away from moisture and heat.
