Question
I recently had gotten hives and had to take a Benadryl. However i am in a drug program and get random tests. I am wondering if Benadryl is something that will show up or alter my test? and if so for how long does it show?

Answer
Dear Louie

The active ingredient of Benadryl will probably show up in tests but I doubt anybody would be intereseted in its presence. It is such a common drug and probably half of the population will take it occasionally.

It should be undetectable within 4-5 days of its last use.
