Patient's question:
How long is the effective time of emergency contraception? I had sex the night before yesterday and took emergency contraception in the afternoon yesterday. I had sex again last night and today. Do I need to take another dose of emergency contraception?Doctor's answer:
Based on your description, it is inferred that the effectiveness of emergency contraception is 72 hours. If you have intercourse again before 72 hours have passed, there is no need to take another dose. It is recommended to use a full-course condom during intercourse and avoid breastfeeding. Contraceptive pills should be taken sparingly, as oral contraceptives cannot guarantee 100% breastfeeding success and may still result in pregnancy. Based on your symptoms, it is generally estimated that the effective period of emergency contraception is about 72 hours. Therefore, in your case, there is no need to take another dose of emergency contraception.
