Patient's question:
How effective is emergency contraception within how many hours of taking it?Doctor's answer:
Hello, under normal circumstances, emergency contraception pills are effective when taken within 72 hours after intercourse. Emergency contraception pills contain a high level of estrogen, and the dosage for one emergency pill is equivalent to the amount of a conventional short-term oral contraceptive taken over 8 days. Excessive dosage can lead to gastrointestinal discomfort, menstrual cycle irregularities, ovarian suppression, and other phenomena that disrupt the normal menstrual cycle, causing endocrine disorders. If taken for a long time, severe cases may result in amenorrhea and infertility. Emergency contraception pills should not be taken frequently. If you do not plan to get pregnant in the near future, it is better to use long-term contraception methods such as hormonal contraceptives or condoms to avoid unintended pregnancy.
