Patient's question:
Patient Age: 22Detailed Condition and Purpose of Consultation: I didn't take any contraception before having sex, and it was also the risky period, so I took Postinor (Mifepristone Tablets) for two consecutive days. Will this have any adverse effects?
Medical History: I have taken it once before
Doctor's answer:
Hello, emergency contraception refers to a method of preventing pregnancy after unprotected sex or contraceptive failure within a certain period of time. It is effective within 72 hours after intercourse, and the most commonly used type of emergency contraception is monophasic progestogen, with levonorgestrel as the active ingredient. This type of medication is represented by Yuzhentong. Another type of emergency contraception is antiprogestogen, with the most commonly used being Zengdingnuo, as well as Simian tablets, Biyun capsules, Huadian tablets, etc., with mifepristone as the active ingredient. Emergency contraception can only be effective for the current act of unprotected sex and can only be taken once per menstrual cycle. Even after taking medication in this cycle, other reliable contraceptive measures should still be used during sexual activity. Additionally, emergency contraception is only a temporary remedy and should absolutely not be used repeatedly as a regular contraceptive method. Because emergency contraception contains a relatively high dose of hormones, it may have certain side effects. Most women will experience on-time menstruation, while a portion of women may experience early or delayed periods. If menstruation is delayed by one week, a urine pregnancy test should be conducted to confirm whether it is a failure of emergency contraception.
