Uses For Zovia 1/35e
Ethinyl estradiol and ethynodiol diacetate combination is used to prevent pregnancy. It is a birth control pill that contains two types of hormones, ethinyl estradiol and ethynodiol diacetate, 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.

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

Take this medicine 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.

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, talk 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.
