Uses For ethinyl estradiol and norgestimate
Ethinyl estradiol and norgestimate combination is used to prevent pregnancy. It is a birth control pill that contains two types of hormones, ethinyl estradiol and norgestimate, 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 is prevented.
Ethinyl estradiol and norgestimate combination is also used to treat moderate acne in females (at least 15 years of age) who started having menstrual period and also wants to use ethinyl estradiol and norgestimate for birth control.
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.
ethinyl estradiol and norgestimate does not prevent HIV infection or other sexually transmitted diseases. It will not help as emergency contraception, such as after unprotected sexual contact.
ethinyl estradiol and norgestimate is available only with your doctor's prescription.

Proper Use of ethinyl estradiol and norgestimate
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.
ethinyl estradiol and norgestimate comes with patient instructions. Read and follow these instructions carefully. Ask your doctor or pharmacist if you have any questions.
ethinyl estradiol and norgestimate is available in blister packs with a Dialpak® tablet dispenser or a Veridate® 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 ethinyl estradiol and norgestimate, 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 ethinyl estradiol and norgestimate at the same time each day. 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 ethinyl estradiol and norgestimate. If your nausea is continuous and does not go away, call your doctor.
Follow the instructions in the patient leaflet or call your doctor if you vomit or have diarrhea within 3 to 4 hours of taking ethinyl estradiol and norgestimate.
The dose of ethinyl estradiol and norgestimate 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 ethinyl estradiol and norgestimate. 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.
