A member asked:

How does plan b work, and how long does the medication stay in your body?

A doctor has provided 1 answer

Preventing ovulation: The medication works by inhibitting ovulation. Thus, no egg, no pregnancy! the half-life of the medication varies greatly ranging from 11 to 45 hours and so it is difficult to say for sure. Based on this, it stays in the body for about 2.5 days to just over 1 wk. If you still have question, post it here or consult your doc. Good luck.
