The manufacturer of the emergency contraceptive offers the efficacy of the pill when it is taken as directed. Logically, the longer the interval between unprotected sex and taking the pill, the decrease in how effective it will be.
It is estimated that Postinor-2 will prevent 85% of expected pregnancies. 95% of expected pregnancies will be prevented if taken within the first 24 hours, declining to 58% if taken between 48 hours and 72 hours after unprotected intercourse.
It is not known whether Postinor-2 is effective if taken more than 72 hours after unprotected intercourse.
