Yes. Benadryl is a cold medicine, but it has another use as a sleep aid.

Benadryl (chemical name is "Diphenhydramine") can be found in TylenolPM, Unisom, Nytol, and a lot of the other name brand and store brand OTC sleep aids.

I have a shellfish allergy, it's not too bad, I just get hives from it, and take Benadryl whenever I somehow get my non-seafood meals cross-contaminated with shellfish.

When I ran out of Benadryl one day, my dad handed me a bottle of a storebrand sleep aid that is just Benadryl. Even the pills looked the same except for the color (store brand Benadryl is pink, this OTC sleep aid is baby blue) Since Benadryl no longer seems to make me sleepy, I carry that bottle with me when we go out to eat, just in case someone ignores me when I tell them not to cook my food anywhere near the seafood.
