Contraceptive pills are also known as birth control pills and oral contraceptives. Women take these pills to prevent pregnancy, and sometimes for the treatment of health conditions such as endometriosis. Birth control pills are available only with a doctor's prescription.
Time Frame
Some oral contraceptives are taken for 21 days each month, and others are taken for 28 days. A menstrual period will follow the last active pill, which is usually on day 21. Other brands of contraceptives only produce a menstrual period every 90 days.
Function
Birth control pills are over 99 percent effective in preventing pregnancy. They work by preventing ovulation, thickening cervical mucus, and changing the lining of the uterus to prevent implantation of a fertilized egg.
Benefits
Oral contraceptives can benefit a woman's health. They can cause lighter periods, reducing the risk of anemia. They can also prevent certain cancers and reduce acne.
Side Effects
Most side effects that occur with contraceptive pills are mild and resolve within a couple of months, or with a change of prescription. These include nausea, vomiting, irregular bleeding, breast swelling and mood swings.
Warning
Women over the age of 35 who smoke should not take birth control pills. These women are at greater risk of blood clots, heart attacks and strokes.
