What are ethinyl estradiol; ethynodiol diacetate tablets?
ETHINYL ESTRADIOL/ETHYNODIOL DIACETATE products are effective as oral contraceptives (birth control pills or "the pill"). These products combine natural or synthetic estrogens and progestins, similar to the natural sex hormones (estrogen and progesterone) produced in a woman's body. Ethinyl estradiol is an estrogen and ethynodiol diacetate is a progestin. These products can prevent ovulation and pregnancy. In general, a combination of estrogen and progestin works better than a single-ingredient product. Ethinyl estradiol/ethynodiol diacetate tablets can also help regulate menstrual flow, treat acne or may be used for other hormone related problems in females. The type and amount of estrogen and/or progestin may be different from one product to another.

What should I watch for while taking ethinyl estradiol; ethynodiol diacetate?
Visit your prescriber or health care provider for regular checks on your progress. You should have a complete check-up every 6 to 12 months. If you have any unusual vaginal bleeding contact your doctor or health care provider for advice. If you miss a period, the possibility of pregnancy must be considered. See your prescriber or health care professional as soon as you can.
Use an additional method of contraception during the first cycle that you take these tablets.
If you stop taking these tablets and want to get pregnant, a return to normal ovulation can take some time. You may not return to normal ovulation and fertility for 3 to 6 months. Discuss your pregnancy plans with your health care provider.
If you are taking oral contraceptives for the treatment of acne, hirsutism (male-like hair growth), endometriosis or other hormone related problems, it may take several months of continued treatment to notice improvement in your symptoms or condition.
Tobacco smoking increases the risk of getting a blood clot or having a stroke while you are taking oral contraceptives, especially if you are more than 35 years old. You are strongly advised not to smoke.
Oral contraceptives can increase your sensitivity to the sun and you may burn more easily. Use sunscreen and protective clothing during long periods outdoors. Tanning booths should be used with caution.
If you wear contact lenses and notice visual changes, or if the lenses begin to feel uncomfortable, consult your eye care specialist.
In some women, tenderness, swelling, or minor bleeding of the gums may occur. Notify your dentist if this happens. Brushing and flossing your teeth regularly may help limit this. See your dentist regularly and inform your dentist of the medicines you are taking.
You may get a vaginal yeast infection. If you have never had a yeast infection before, see your prescriber or other health care provider to confirm the problem. If you have had yeast infections in the past and are comfortable with self-medicating the problem, get and use a nonprescription medication to treat the yeast infection.
If you are going to have elective surgery, you may need to stop taking your contraceptive pills one month beforehand. Consult your health care professional for advice prior to scheduling the surgery.
Taking contraceptive pills does not protect you against HIV infection (AIDS) or any other sexually transmitted diseases.
