Brief Answer:
It will leave your system completely. Elimination half life is 24 hours.

Detailed Answer:

Hello,

I can assure you that Levonorgestrel (The active medicine in Plan-B) will be eliminated from your body completely within 3 to 5 days.

The elimination half life for this drug is 24 hours +/- 5 hours, that means by 24 hours, half the medicine you took would be removed from your body and similarly, it keeps on getting removed and will be totally removed from the body in 3 to 5 days after a single dose of plan-B.

The side effects will subside in 2 to 3 days.

Do not worry, you will be fine.

I hope I have answered your question adequately. You can write back to me if you have any doubts.

Best wishes.
