Uses for Nor-QD

Norethindrone is used to prevent pregnancy. It works by stopping a woman's egg from fully developing each month. The egg can no longer accept a sperm and fertilization (pregnancy) is prevented.

Norethindrone is also used to treat secondary amenorrhea (absence of menstrual periods in women who have previously had a menstrual period who are not pregnant), endometriosis, and irregular menstrual periods caused by hormonal imbalance.

No contraceptive method is 100 percent effective. Birth control methods such as having surgery to become sterile or not having sex are more effective than birth control pills. Discuss your options for birth control with your doctor.

This medicine does not protect against HIV infection or other sexually transmitted diseases. It will not help as emergency contraception, such as after unprotected sexual contact.

This medicine is available only with your doctor's prescription.

Precautions while using Nor-QD

It is very important that your doctor check your progress at regular visits to make sure this medicine is working properly and does not cause unwanted effects. These visits will usually be every 6 to 12 months, but some doctors require them more often. Pelvic exam, breast exam, and mammogram (breast x-ray) may be needed to check for unwanted effects, unless your doctor tells you otherwise. Be sure to keep all appointments.

Although you are using this medicine to prevent pregnancy, you should know that using this medicine while you are pregnant could harm the unborn baby. If you think you have become pregnant while using the medicine, tell your doctor right away.

Vaginal bleeding of various amounts may occur between your regular menstrual periods during the first 3 months of use. This is sometimes called spotting when slight, or breakthrough bleeding when heavier.

Check with your doctor right away if you miss a menstrual period. Missed periods may occur if you skip one or more tablets and have not taken your pills exactly as directed. If you miss two periods in a row, talk to your doctor. You might need a pregnancy test.

If you suspect that you may be pregnant, stop using this medicine immediately and check with your doctor.

Check with your doctor before refilling an old prescription, especially after a pregnancy. You will need another physical examination and your doctor may change your prescription.

You may have a higher risk of an ovarian cyst or an ectopic pregnancy (occurs outside the womb) if you get pregnant while using this medicine. These can be serious and life-threatening conditions. It can also cause problems that may make it harder for you to become pregnant in the future. Call your doctor right away if you have a sudden or severe lower abdominal or stomach pain.

Do not use this medicine if you smoke cigarettes. If you smoke while using birth control pills, you increase your risk of having a heart attack, stroke, or blood clot. Your risk is even higher if you have diabetes, high blood pressure, high cholesterol, or if you are overweight. Talk with your doctor about ways to stop smoking. Keep your diabetes under control. Ask your doctor about diet and exercise to control your weight and blood cholesterol level.

Check with your doctor immediately if you have trouble wearing contact lenses or if blurred vision, difficulty with reading, or any other change in vision occurs during or after treatment. Your doctor may want you to have your eyes checked by an ophthalmologist (eye doctor).
