Information on Birth Control Pills »
Birth control pills are also known as oral contraceptives (OCs) or, simply, “the pill.” They offer protection against pregnancy by blocking the union of sperm and egg, thereby preventing conception.
Oral contraceptives or birth control pills contain synthetic female hormones. They work largely by preventing the release of an egg from an ovary, or ovulation. If no egg is released, there can be no pregnancy.
Stopping ovulation is not the only way birth control pills can work. The progestin or synthetic progesterone in birth control pills also changes the physical and chemical environment of the female reproductive tract, making it hostile for sperm.
The active ingredients in birth control pills are synthetic versions of the female hormones estrogen and progesterone. Combination oral contraceptives are birth control...
Ethinyl estradiol and levonorgestrel contains a combination of 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 levonorgestrel are used as contraception to prevent pregnancy.
Ethinyl estradiol and levonorgestrel may also be used for other purposes not listed in this medication guide.

Do not use this medication if you have a history of stroke or blood clot, circulation problems (especially if caused by diabetes), a hormone-related cancer such as breast or uterine cancer, abnormal vaginal bleeding, liver disease or liver cancer, severe high blood pressure, migraine headaches, a heart valve disorder, or a history of jaundice caused by birth control pills.
