Postinor 2 prevents pregnancy by preventing ovulation. It is intended to be used in emergency situation, and not for routine birth control. So, it works once if taken correctly and should never be taken frequently.
It is most effective if taken as soon as possible and should be taken within 72 hours of unprotected sex or contraceptive failure, like the condom broke.
