Uses for Cryselle

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 surgery to become sterile or abstaining from 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 Cryselle

It is very important for your doctor to monitor your progress at regular visits to ensure this medicine is effective and does not cause unwanted side 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 be aware that using this medicine while pregnant could harm your unborn baby. If you think you might be pregnant while taking this medicine, inform your doctor immediately.

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 suspect you may be pregnant, stop using this medicine and consult your doctor right away. 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 may also lead to future difficulties in becoming pregnant.

Do not use this medicine along with any medicine for treating 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. Inform 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 is a concern for you, discuss it with your doctor.

You might experience light bleeding or spotting when you first start taking 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, 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 having 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 are overweight. Discuss ways to stop smoking with your doctor. Keep your diabetes under control. Ask your doctor about diet and exercise to manage your weight and blood cholesterol levels.

Using this medicine may raise your risk of blood clotting problems. Contact your doctor immediately if you experience chest pain, groin or leg pain (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 taking this medicine.

Using this medicine may increase 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 right away if you notice abnormal vaginal bleeding.

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

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

This medicine may increase your risk of gallbladder disease. Consult your doctor if you begin to experience stomach pain, nausea, and vomiting.

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

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

You should use a second form of birth control (eg, condoms, diaphragms, or contraceptive foams and jellies) when you first start using this medicine.

It is very important that you take this medicine on time every day. Birth control pills work best when there is no more than 24 hours between doses.

You could have light bleeding or spotting 3 days after you stop taking a white tablet, or when you switch to ethinyl estradiol and norgestrel combination from another birth control pill or implant, or injection.

If you miss a dose of this medicine, take it as soon as possible. However, if it is almost time for your next dose, skip the missed dose and go back to your regular dosing schedule. Do not double doses.

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.

If you started this medicine on Day 1 of your period and you miss two white pills in a row during Week 3, throw out the rest of your pills and start a new pack the same day. If you miss three or more white pills in a row during any week, throw out the rest of your pills and start a new pack the same day. Use a second form of birth control until you have been taking white pills for seven days in a row.

If you started this medicine on the Sunday after your period started and you miss two white pills in a row during Week 3, keep taking one pill every day until the next Sunday. Then throw away the rest of your pills and start a new pack on that same Sunday. Use a second form of birth control until you have been taking white pills for seven days in a row.

If you started this medicine on the Sunday after your period started and you miss three or more white pills in a row during any week, keep taking one pill every day until the next Sunday. Then throw away the rest of your pills and start a new pack on that same Sunday. Use a second form of birth control until you have been taking white pills for seven days in a row.

If you miss your pills and change your schedule, you may not have a period for that month. Make sure your doctor knows if you miss your period two months in a row, because you may be pregnant.

You could have light bleeding or spotting any time you do not take a pill on time. The more pills you miss, the more likely you are to have bleeding.
