Emergency contraceptive pills for 72 hours after unprotected intercourse

Contraceptive pills are compound preparations composed of different types of estrogens and (or) progestins. Short-acting contraceptive pills include norgestrel compound tablets, megestrol acetate, and nonoxynol ether suppositories; long-acting contraceptive pills include norgestrel compound tablets and chlormadinol acetate tablets; emergency contraceptive pills include levonorgestrel tablets, megestrol acetate tablets, and norgestrel tablets. In addition, male contraceptive pills include gossypol acetate compound tablets and cyproterone acetate. Please use the medicine under the guidance of a doctor. Emergency contraceptive pills (ECPs) are contraceptive measures taken after sexual intercourse to avoid unwanted pregnancy. Currently, the emergency contraceptive drugs used in countries around the world mainly include the following two categories: containing ulipristal acetate or containing levonorgestrel. The most common emergency contraceptive pills on the Chinese market currently contain levonorgestrel, which can delay or stop the release of egg cells, thereby achieving a contraceptive effect. Emergency contraceptive pills should be taken as soon as possible after unprotected sexual intercourse, preferably within 12 hours. If taken more than 36 hours later, their contraceptive effect will be greatly reduced. Emergency contraceptive pills should only be used as a backup method to prevent pregnancy and should not be used as a regular contraceptive measure [1].
