PLEASE HELP ME! Ive accidently been overdosing on antihistamines for MONTHS, natural way to cleanse my system?

How long does an Antihistamine stay in your system?
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 antihistamines (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?

Mainly I want to know how long would the antihistamines stay in my system? Ive completely stopped taking them as of now.

Benadryl or diphenhydramine has a half life of 2-8 hours. This means every 2-8 hours (depending on the individual), your body would have got rid of half the dose you took. That means once you stop taking any more, your system will get rid of it in a matter of few days (or even in one day). Let us assume you have 100 mgs (each capsule of benadryl contains 25 mgs of diphenhydramine) in your systemn, in 8 hours you have only 50 mgs left, in 16 hours you will have only 25 mgs left, in 24 hours you will have 12.5 mgs left (half capule) and so on.
Drinking a lot of water (in moderation of course) will help the excretion process since most drugs eventually get excreted after metabolism through the kidneys as urine. Pharmacy assistant Professor
