Birth Control Pill
Updated:The birth control pill, also known as the oral contraceptive pill or simply "the pill", is a form of hormonal contraception taken orally by women to prevent pregnancy. The pill contains synthetic versions of the female hormones estrogen and progestin, which work to prevent ovulation, thicken cervical mucus to block sperm, and thin the uterine lining to prevent implantation.
Birth control pills are highly effective at preventing pregnancy when taken correctly. They are usually taken daily for 21 days, followed by a 7-day break during which menstruation occurs. Some newer pill packs are designed for continuous use with no break.
Additional Information
In addition to pregnancy prevention, the birth control pill can offer other benefits such as regulating menstrual cycles, reducing menstrual cramps and acne, and lowering the risk of certain cancers. However, it does not protect against sexually transmitted infections (STIs).
Birth control pills require a prescription and may have some side effects such as nausea, breast tenderness, and spotting between periods, especially when first starting. Serious risks are rare but can include blood clots, stroke, and heart attack, particularly in women who smoke or are over 35.
Examples
A woman takes a birth control pill at the same time every day to prevent pregnancy.
A couple chooses to use the pill as their primary form of contraception.
