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...

Necon (norethindrone and ethinyl estradiol) is used as contraception to prevent pregnancy. It is also used to treat severe acne. Necon contains a combination of female hormones that prevent ovulation. This medication is available in generic form. Common side effects include nausea, vomiting, headache, stomach cramping/bloating, dizziness, vaginal discomfort/irritation, increased vaginal fluids, or breast tenderness/enlargement. Acne may improve or get worse. Vaginal bleeding between periods (spotting) or missed/irregular periods may occur, especially during the first few months of use.
Necon is a 28-day regimen of tablets, 21 have active medication (hormones) and 7 are inert reminder pills. Take one active pill once daily for 21 days in a row, and then an inactive pill once daily for 7 days after you have taken the last active pill. Follow the schedule as prescribed by your doctor. Necon may interact with acetaminophen, ascorbic acid (vitamin C), prednisolone, theophylline, St. John's wort, antibiotics, seizure medications, barbiturate sedatives, or HIV or AIDS medications. Tell your doctor all medications you are taking. Necon must not be used during pregnancy. If you become pregnant or think you may be pregnant, tell your doctor immediately. If you have just given birth or had a pregnancy loss/abortion after the first 3 months, talk with your doctor about reliable forms of birth control, and find out when it is safe to start using birth control that contains a form of estrogen, such as this medication. This medication passes into breast milk. This may affect milk production and may have undesirable effects on a nursing infant. Consult your doctor before breast-feeding.
