how long does a Antihistamine stay in your system before they are COMPLETELY out of your system?
IS there anyway to help it along?

About nine months ago I started taking benadryl for allergies, taking about 6 to 8 a day.. as well as taking tylenol pm at night (usually 4 a night) I wasnt aware that the pm in tylenol is the same thing as benadryl.. now im aware that I was taking WAY too much diphenhydramine (benadryl).
So since ive been taking too much and for so long.. how long do you think it would take to flush it out?
Should i drink a lot of water? any other suggestions?

1. a few hours, usually, but it depends on how much you take and what you take
2. lots of water or some exercise, but the water works best

It depends on what antihistamine you took. Some are 24 hours while others last about 4 hours.

anywhere from 4 to 6 hours. it depends on what you took. if you are having trouble breathing you need to go to the hospital, you maybe having a reaction to the medication.
