A member asked:

How long does it take for the side effects of the plan b pill to wear off?

It depends: Some of the side effects from Plan B can mimic pregnancy and Plan B is only 75% effective. You should still check a home pregnancy test, especially if you're late for your period. Otherwise, side effects can last up to 10 days.

Within 72 hours: The immediate effects should be gone within 72 hours. If they persist, see your doctor.
