What Is an Oral Contraceptive? The Pill on Labels Explained
Oral Contraceptive · say it: OR-ul kon-truh-SEP-tivAlso written: birth control pill, the pill, combined pill, progestin-only pill, mini-pill, COC, POP
Short answer
An oral contraceptive is a birth control pill taken by mouth that uses hormones to prevent pregnancy.
What it means
An oral contraceptive is a hormone pill taken by mouth to prevent pregnancy. Combined pills contain an estrogen and a progestin; progestin-only pills (sometimes called the mini-pill) contain only a progestin. They work mainly by stopping ovulation and thickening cervical mucus, depending on the type.
Oral contraceptives appear on labels in two ways. Their own labels warn about blood clots (especially with combined pills, and more so in smokers over 35 and in some other risk groups) and explain what to do about missed pills. Other medicine labels mention oral contraceptives because some medicines, such as certain anti-seizure medicines and rifampin, can make the pill less effective.
The pill does not protect against sexually transmitted infections. Vomiting or severe diarrhea soon after a pill can also mean it was not absorbed, which the leaflet explains.
