What is Previfem (ethinyl estradiol and norgestimate)?
Ethinyl estradiol and norgestimate is a combination drug that contains female hormones that prevent ovulation (the release of an egg from an ovary). This medication also causes changes in your cervical mucus and uterine lining, making it harder for sperm to reach the uterus and harder for a fertilized egg to attach to the uterus.
Ethinyl estradiol and norgestimate is used as contraception to prevent pregnancy.
Ethinyl estradiol and norgestimate may also be used for purposes not listed in this medication guide.
What is the most important information I should know about birth control pills?
Do not use birth control pills if you are pregnant or if you have recently had a baby.
You should not take birth control pills if you have any of the following conditions: unusual vaginal bleeding, chest pain, uncontrolled high blood pressure, an uncontrolled heart valve disorder, diabetic problems with your eyes or kidneys, liver cancer, severe migraine headaches, or if you have ever had breast or uterine cancer, jaundice caused by pregnancy or birth control pills, a heart attack, a stroke, or a blood clot.
Smoking can increase your risk of blood clot, stroke, or heart attack while taking birth control pills, especially if you are older than 35 years of age.
What should I discuss with my healthcare provider before taking birth control pills?
Smoking can increase your risk of blood clots, stroke, or heart attack while taking birth control pills, especially if you are older than 35 years of age. Your risk increases the more you smoke. You should not take combination birth control pills such as ethinyl estradiol and desogestrel if you smoke and are older than 35 years of age.
This medicine can cause birth defects. Do not use if you are pregnant. Tell your doctor right away if you become pregnant, or if you miss two menstrual periods in a row. If you have recently had a baby, wait at least 4 weeks before taking birth control pills.
You should not take birth control pills if you have:
unusual vaginal bleeding that has not been checked by a doctor;
history of heart attack, stroke, or blood clot;
uncontrolled heart valve disorder;
untreated or uncontrolled high blood pressure;
problems with your eyes, kidneys or circulation caused by diabetes;
a history of hormone-related cancer such as breast or uterine cancer;

a history of depression;
liver or kidney disease;
seizures or epilepsy;
a history of irregular menstrual cycles; or

The hormones in birth control pills can pass into breast milk and may harm a nursing baby. This medication may also slow breast milk production. Do not use if you are breast feeding a baby.
How should I take birth control pills?
Follow all directions on your prescription label. Do not take this medicine in larger or smaller amounts or for longer than recommended.
You will take your first pill on the first day of your period or on the first Sunday after your period begins. You may need to use back-up birth control, such as condoms or a spermicide, when you first start using this medicine. Follow your doctor's instructions.
Take one pill every day, no more than 24 hours apart. When the pills run out, start a new pack the following day. You may get pregnant if you do not take one pill daily. Get your prescription refilled before you run out of pills completely.
The 28 day birth control pack contains seven "reminder" pills to keep you on your regular cycle. Your period will usually begin while you are using these reminder pills.
You may have breakthrough bleeding, especially during the first 3 months. Tell your doctor if this bleeding continues or is very heavy.
Use a back-up birth control if you are sick with severe vomiting or diarrhea.
If you need surgery or medical tests or if you will be on bed rest, you may need to stop using this medication for a short time. Any doctor or surgeon who treats you should know that you are using birth control pills.
While taking birth control pills, you will need to visit your doctor regularly.
Store this medication at room temperature away from moisture and heat.
What happens if I miss a dose?
Follow the patient instructions provided with your medicine. Ask your doctor or pharmacist if you do not understand these instructions. Missing a pill increases your risk of becoming pregnant.
If you miss one active pill, take two pills on the day that you remember. Then take one pill per day for the rest of the pack.
If you miss two active pills in a row in Week 1 or 2, take two pills per day for two days in a row. Then take one pill per day for the rest of the pack. Use back-up birth control for at least 7 days following the missed pills.

If you miss three active pills in a row in Week 1, 2, or 3, throw out the rest of the pack and start a new pack on the same day if you are a Day 1 starter. If you are a Sunday starter, keep taking a pill every day until Sunday. On Sunday, throw out the rest of the pack and start a new pack that day.
If you miss two or more pills, you may not have a period during the month. If you miss a period for two months in a row, call your doctor because you might be pregnant.
If you miss a reminder pill, throw it away and keep taking one reminder pill per day until the pack is empty. You do not need back-up birth control if you miss a reminder pill.
