HOW DOES PLAN B ONE-STEP WORK?

Spoiler alert! Wishing on a dandelion can't help prevent pregnancy after unprotected sex or birth control. Plan B One-Step can help. Use as directed.

Plan B One-Step is one tablet that contains levonorgestrel, a hormone that has been used in many birth control pills for several decades. Plan B One-Step contains a higher dose of levonorgestrel than birth control pills, but works in a similar way to help prevent pregnancy.

Plan B One-Step works mainly by stopping the release of an egg from the ovary. It is possible that Plan B One-Step may also work by preventing fertilization of an egg (the uniting of sperm with the egg) or by preventing attachment (implantation) to the uterus (womb).

How effective is Plan B One-Step?

When taken as directed, Plan B One-Step can significantly decrease the chance you will get pregnant. About 7 out of 8 women who would have gotten pregnant will not become pregnant after taking Plan B One-Step.

But remember: Plan B One-Step should not be used as a regular birth control method because it’s not as effective.

NO B.S.
JUST PLAN B ONE-STEP
