What is the emergency contraceptive pill? It’s the pill you take to prevent pregnancy after you’ve had sex with your partner! That’s true, but it’s a bit superficial to explain it that way. The emergency contraceptive pill, we should at least understand its ingredients, side effects, and the principle of action, only to have a comprehensive analysis of it, in order to help us to the greatest extent possible to prevent pregnancy, but also to reduce the damage to our bodies. What is the emergency contraceptive pill? The emergency contraceptive pill is a contraceptive method used to prevent pregnancy during unprotected sex or for a period of time after the failure of contraception, of which the pill is the most common method. It is effective within 72 hours after intercourse, but if you have sex during the pill, the time should be re-calculated, and the earlier you take it, the better it is. What are the common emergency contraceptive pills and how to take them? Yutin (levonorgestrel tablets) take the first tablet (0.75mg) within 72 hours after intercourse, and take the second tablet (0.75mg) after 12 hours, for a total of two tablets. This product is an emergency contraceptive and should not be taken as a regular contraceptive. Levonorgestrel enteric coated capsules can be taken within 72 hours after intercourse. What are the problems to be noted for emergency contraception? Take the emergency contraceptive pill within 72 hours (the sooner the better) after contraceptive failure or contraceptive-free intercourse. Get the method of taking the pill right: taking the emergency contraceptive pill after meals or before going to bed can slow down the side effects such as nausea and vomiting. If vomiting occurs within 2 hours after taking the pill, you should immediately take the same dose of emergency contraceptive pills and additional antiemetic medication. After taking the emergency contraceptive pill, no further intercourse without contraception should occur during the current menstrual cycle. If you have intercourse again, you should use regular methods of contraception. If menstrual periods occur, a hospital visit should be made to perform a pregnancy test to determine if emergency contraception has failed. References: [1] Lu JZ. Contraceptive pills [J].
