After unprotected vaginal intercourse, emergency contraceptive pills can reduce the risk of pregnancy if used as late as?

Emergency contraceptive pills (ECPs) are designed to prevent pregnancy after unprotected intercourse or contraceptive failure. The timing of taking ECPs is crucial for their effectiveness. Certain types of ECPs, such as those containing ulipristal acetate, can be effective if taken up to 120 hours (5 days) after intercourse. This extended window allows individuals more time to access emergency contraception compared to older methods, such as levonorgestrel, which is most effective when taken within 72 hours.

Using ECPs within this 120-hour timeframe can significantly reduce the risk of pregnancy, especially if ovulation has not yet occurred. This is particularly valuable information for those needing to make quick decisions about their reproductive health. Understanding the effectiveness period of various types of emergency contraceptive pills is essential for providing appropriate care and guidance to those in need.
