Postinor 2 prevents a pregnancy before it is established by preventing or delaying the release of an egg from the ovary.
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.
The pill does not prevent conception, only effective to prevent ovulation.
