If you look at the label of TylenolPM and Benadryl you will find they have
the same amount of the active ingredient, diphenhydramine.

As I understand it, that the manufacturer of Benedryl actually
attempted to get it FDA certified with a secondary use as a sleeping
pill back in the day when it first came out. Doctors figured out it
worked well as a sleeping pill as well and were off-label prescribing
it.

The next poster, Viperdoc, is more knowledgable here than I am--but all
(I believe) over-the-counter sleep aids are antihistamines. The "first
generation" antihistamines such as diphenhydramine (Benadryl) are quite
sedating, and those drugs make a feature out of that bug.

Do sleep aids contain antidepressant or antihistamines? I don't take
them
so I legitimately don't know.
