Levonelle effectiveness

The most important question to ask about Levonelle - how good is Levonelle at preventing pregnancy?

Levonelle contains levonorgestrel, a synthetic version of the progesterone hormone. Levonelle primarily works by preventing the release of an egg from the ovaries (ovulation). It also increases the thickness of the mucus around the cervix, which helps by creating a barrier, making it difficult for sperm to pass through and enter the cervix.

Levonelle has a 95% effectiveness rate if taken 12 hours after unprotected sex. After 48 hours, the effectiveness of Levonelle reduces to 58%. Other morning0after pill brands, such as ellaOne can be effective up to 5 days after intercourse.
