Microgestin 1/20

Generic name: Ethinyl Estradiol And Norethindrone

Usage of Microgestin 1/20

Ethinyl estradiol and norethindrone combination is used to prevent pregnancy. It is a birth control pill that contains two types of hormones, ethinyl estradiol and norethindrone, and when taken properly, prevents 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, 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 prevent 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.

    • How to use Microgestin 1/20

    It is very important that you use this medicine exactly as directed by your doctor. Do not use more of it, do not use it more often, and do not use it for a longer time than your doctor ordered.

    To make using oral contraceptives as safe and reliable as possible, you should understand how and when to take them and what effects may be expected.

    This medicine comes with patient instructions. Read and follow these instructions carefully. Ask your doctor or pharmacist if you have any questions.

    This medicine is available in blister packs with a Dialpak® tablet dispenser. Each blister pack contains 28 tablets with different colors that need to be taken in the same order as directed on the blister pack.

    When you begin using this medicine, your body will require at least 7 days to adjust before a pregnancy will be prevented. Use a second form of contraception, such as a condom, spermicide, or diaphragm, for the first 7 days of your first cycle of pills.

    Take this medicine at the same time each day (with meals or at bedtime). Birth control pills work best when no more than 24 hours pass between doses.

    Do not skip or delay taking your pill by more than 24 hours. If you miss a dose, you could get pregnant. Ask your doctor for ways to help you remember to take your pills or about using another method of birth control.

    You may feel sick or nauseated, especially during the first few months that you take this medicine. If your nausea is continuous and does not go away, call your doctor.

    Do not eat grapefruit or drink grapefruit juice while you are using this medicine. Grapefruit and grapefruit juice may change the amount of this medicine that is absorbed in the body.

    Dosing

    The dose of this medicine will be different for different patients. Follow your doctor's orders or the directions on the label. The following information includes only the average doses of this medicine. If your dose is different, do not change it unless your doctor tells you to do so.

    The amount of medicine that you take depends on the strength of the medicine. Also, the number of doses you take each day, the time allowed between doses, and the length of time you take the medicine depend on the medical problem for which you are using the medicine.

    Your doctor may ask you to begin your dose on the first day of your menstrual period (called Day 1 start) or on the first Sunday after your menstrual period starts (called Sunday start). When you begin on a certain day it is important that you follow that schedule, even if you miss a dose. Do not change your schedule on your own. If the schedule that you use is not convenient, check with your doctor about changing it. For a Sunday start, you need to use another form of birth control (eg, condom, diaphragm, spermicide) for the first 7 days.

    You should begin your next and all subsequent 28-day regimens of therapy on the same day of the week as the first regimen began and follow the same schedule.

  • For oral dosage form (tablets):
  • For contraception (to prevent pregnancy):
  • Adults and teenagers—
  • Loestrin® 21: One white or green tablet (active) taken at the same time each day for 21 consecutive days followed by one week without the tablets.
