User Comments about Benadryl Allergy
16 Feb 2014 I took one Benadryl, which made me very sleepy. After about three hours, while walking from the kitchen to the living room, I felt a wave of nausea, then fainted. I was out only a few seconds, and was lucky not to have hurt myself. I have taken Benadryl occasionally in the past and only experienced the drowsiness. I don't think I'll risk fainting again. I am in generally good health, no blood pressure or heart problems, so this was a suprise.
