Ethinyl Estradiol and Norgestimate (Oral Contraceptives)

pronounced as (eth′ i nil es″ tra dye′ ol)

Brand Name(s): Estarylla®, Mili®, Mono-Linyah®, Ortho-Cyclen®, Ortho Tri-Cyclen®, Previfem®, Sprintec®

Why is this medicine prescribed?

Oral contraceptives (birth-control pills) containing ethinyl estradiol (an estrogen) and norgestimate (a progestin) are used to prevent pregnancy. Estrogen and progestin are two female sex hormones. Combinations of estrogen and progestin work by preventing ovulation (the release of eggs from the ovaries).

Oral contraceptives are an effective method of birth control, but they do not prevent the spread of human immunodeficiency virus (HIV, the virus that causes acquired immunodeficiency syndrome [AIDS]) and other sexually transmitted diseases.

Are there other uses for this medicine?

Oral contraceptives are also sometimes used to treat heavy or irregular menstruation and endometriosis (a condition in which the type of tissue that lines the uterus [womb] grows in other areas of the body and causes pain, heavy or irregular menstruation [periods], and other symptoms). Talk to your doctor about the risks of using this medication for your condition.

Oral contraceptives are also used to treat acne in certain patients. Oral contraceptives treat acne by decreasing the amounts of certain natural substances that can cause acne.

This medication may be prescribed for other uses; ask your doctor or pharmacist for more information.

How should this medicine be used?

Ethinyl estradiol and norgestimate oral contraceptives come as tablets to take by mouth. Take once a day on the days specified by your doctor. Take your oral contraceptive at around the same time on those days.

Take ethinyl estradiol and norgestimate oral contraceptives exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.

Ethinyl estradiol and norgestimate oral contraceptives come in many different brands. Different brands of oral contraceptives contain different doses and may also contain inactive tablets or ones containing iron. Oral contraceptives are taken on specific schedules. Be sure that you know which brand of oral contraceptives you are using and exactly how you should use it. Ask your pharmacist or doctor for a copy of the manufacturer's information for the patient and read it carefully.

Your doctor will tell you when you should start taking your oral contraceptive. It is usually started on the first day of your menstrual period or on the first Sunday after bleeding begins. You will probably be told to use another method of birth control during the first 7 days that you take your oral contraceptive. Talk to your doctor or pharmacist about what method is best for you. Follow these directions carefully to prevent pregnancy.

You will probably experience withdrawal bleeding similar to a menstrual period while you are taking the inactive tablets or during the time that you do not take your oral contraceptive. If you are taking the type of packet that only contains active tablets, you will not experience any scheduled bleeding, but you may experience unexpected bleeding and spotting, especially at the beginning of your treatment. Be sure to start taking your new packet on schedule even if you are still bleeding.

If you vomit or have diarrhea while you are taking ethinyl estradiol and norgestimate oral contraceptives, it may not work as well. If this happens, contact your doctor about what to do. You may be told to use a back-up method for 7 days. Talk to your doctor about an appropriate backup method of birth control in case it is needed at any point during therapy.

Ethinyl estradiol and norgestimate oral contraceptives will work only as long as they are taken regularly. Continue to take them as directed even if you are spotting or bleeding, have an upset stomach, or do not think that you are likely to become pregnant. Do not stop taking oral contraceptives without talking to your doctor.
