Patient's question:
My sister bought emergency contraception but doesn't know how long after taking it is effective. She's afraid of missing the best time. How many hours after taking emergency contraception is it effective?Doctor's answer:
Emergency breastfeeding refers to the method of breastfeeding used to prevent pregnancy after unprotected intercourse or a period of successful breastfeeding. If taken within 72 hours, it will be completely ineffective. Drug breastfeeding is the most common method. This emergency contraceptive can be taken within 72 hours after sexual intercourse. The earlier breastfeeding occurs, the better the effect. However, it is advisable to take emergency contraceptives sparingly, as excessive consumption may lead to endocrine disorders, irregular menstruation, and abnormal vaginal bleeding. It is recommended to adopt appropriate breastfeeding methods to prevent adverse reactions such as menstrual disorders. Emergency contraceptives should not be taken frequently. If you do not plan to conceive in the near future, it is better to take long-acting contraceptives or use condoms to prevent unintended pregnancy.
