50-80% effective: According to the Medical Letter, Postinor 2 is effective 50-80%. They should be started as soon as possible within 72 hours of unprotected sex. Routine contraception should be continued or initiated as soon as possible following use of levonorgestrel as fertility returns following the use of emergency contraception with levonorgestrel.
