Escapelle/Postinor prevents pregnancy before it becomes established. It primarily works by preventing or delaying the release of an egg from the ovary (ovulation prevention), thus reducing the chances of fertilization. It can also slow down the movement of sperm and affect the uterine lining, preventing implantation. It’s crucial to understand that this pill is not an abortion pill. Escapelle/Postinor is not intended to terminate an existing pregnancy, and it won’t harm one if it already exists.
