Uses for Low-Ogestrel

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

No contraceptive method is 100 percent effective. Birth control methods like 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 will not prevent HIV infection or other sexually transmitted diseases. It will not work as emergency contraception, such as after unprotected sexual contact.

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

Precautions while using Low-Ogestrel

It is very important that your doctor checks your progress at regular visits to ensure this medicine is working properly and does not cause unwanted effects. Your doctor may also want to check your blood pressure while you are using this medicine.

Even though you are using this medicine to prevent pregnancy, using it while you are pregnant could harm your unborn baby. If you think you might be pregnant while using this medicine, tell your doctor immediately.

You may be pregnant if:

  • You do not take the pills regularly and missed a menstrual period.
  • You missed 2 menstrual periods.

If you think you may be pregnant, stop using this medicine and check with your doctor right away. There is a higher risk of an ectopic pregnancy if you become pregnant while using this medicine. An ectopic pregnancy can be serious and life-threatening. It can also cause issues that may make it harder for you to get pregnant in the future.

Do not use this medicine with any medicine that treats hepatitis C virus infection, including ombitasvir/paritaprevir/ritonavir, with or without dasabuvir (Technivie®, Viekira Pak®).

This medicine will not protect you from getting HIV/AIDS, herpes, or other sexually transmitted diseases. Tell your doctor if you or your partner start having sexual intercourse with other people, or if you or your partner test positive for a sexually transmitted disease. If this worries you, talk with your doctor.

You might experience light bleeding or spotting when you first start using this medicine. This is usually normal and should not last long. However, if you have heavy bleeding or if the bleeding lasts more than a few days in a row, call your doctor.

Do not use this medicine if you smoke cigarettes or if you are over 35 years old. Smoking while using ethinyl estradiol and norgestrel combination increases your risk of having a blood clot, heart attack, or stroke. This risk is even higher if you are over 35, 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 manage your weight and blood cholesterol level.

Using this medicine may increase your risk of blood clotting problems. Check with your doctor right away if you experience pain in the chest, groin, or legs, especially the calves, difficulty breathing, a sudden severe headache, slurred speech, sudden unexplained shortness of breath, sudden loss of coordination, or changes in vision while using this medicine.

Using this medicine may increase your risk of breast cancer or cancers of the reproductive organs (e.g., endometrium, ovaries, cervix). Discuss this risk with your doctor. Check with your doctor immediately if you experience abnormal vaginal bleeding.

Check with your doctor right away if you have pain or tenderness in the stomach, dark urine, pale stools, loss of appetite, nausea, vomiting, or yellowing of the eyes or skin. These could be signs of a serious liver issue.

Check with your doctor immediately if you experience blurred vision, difficulty reading, or any other changes in your vision during or after treatment. Your doctor may want an eye specialist (ophthalmologist) to examine your eyes.

This medicine may increase your risk of gallbladder disease. Consult your doctor if you start experiencing stomach pains, nausea, and vomiting.

Ensure that any doctor or dentist treating you knows that you are using this medicine. The results of some medical tests may be affected by this medicine.

Do not take other medicines unless you have discussed them with your doctor. This includes prescription or over-the-counter (OTC) medicines, as well as herbal (e.g., St. John's wort) or vitamin supplements.
