Uses for Ovral

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 a 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 Ovral

It is very important for your doctor to check your progress during 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, you should know that using this medicine while you are pregnant could harm your unborn baby. If you think you might be pregnant while using this medicine, tell your doctor right away.

You may be pregnant if:

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

If you think you may be pregnant, stop using this medicine and contact your doctor immediately. You may have 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 treatments for hepatitis C virus infection, including ombitasvir/paritaprevir/ritonavir, with or without dasabuvir (Technivie®, Viekira Pak®).

This medicine will not protect you from 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 tests positive for a sexually transmitted disease. Discuss any concerns 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 continues for more than a few days in a row, contact 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 a blood clot, heart attack, or stroke. Your 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 for weight and cholesterol management.

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

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

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

Contact your doctor immediately if you experience blurred vision, difficulty reading, or any other changes in 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. Contact your doctor if you start having stomach pains, nausea, or vomiting.

Make sure 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 nonprescription (over-the-counter [OTC]) medicines and herbal products (e.g., St. John's wort) or vitamin supplements.

If you miss one white pill, take it as soon as you can. Then take your next pill at the regular time. This means, you may take two pills in one day. Use a second form of birth control until you have been taking white pills for seven days in a row.

If you miss two white pills in a row during Week 1 or 2, take two pills as soon as you can. Take two more pills on the next day. Then go back to your regular schedule of taking one pill every day. Use a second form of birth control until you have been taking white pills for seven days in a row.

Use a second form of birth control until you have been taking white pills for seven days in a row.
