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 if taken within 72 hours after intercourse. Emergency contraception pills contain high levels of estrogen. The dosage of 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 disrupt the normal menstrual cycle, causing endocrine disorders. Long-term use can, in severe cases, result in amenorrhea and infertility. Emergency contraception pills should not be taken frequently. If you do not plan to become pregnant in the near future, it is advisable to use long-term contraception methods such as birth control pills or condoms to avoid unintended pregnancy.
