Benadryl question.

I've looked on erowid but I just can't find the info I'm looking for. I know with DXM you shouldn't take anything with any other active ingredients besides the DXM. Is diphenhydramine the only active ingredient in Benadryl? If not, are there any diphenhydramine-only products?

pseudoephedrine is, also, an active ingredient.

It looks like you can obtain diphenhydramine hydrochloride in Allerdryl, Benadryl, Benylin Cough, Bydramine, Compoz, Diphen Cough, Nytol, Sleep-Eze 3, and Sominex 2.

Do not combine with amobarbital, amphotericin B, cephalothin, hydrocortisone, phenobarbital, phenytoin, or thiopental.

Thanks beachguy.. much appreciated.
