Do you mean to take to the park or for the room?
Park I just take 2-3 bandaids and some motrin, possibly a couple sudafed tabs if allergy season, and an Imitrex. I'm not carrying anything more and if I need more than a bandaid there is first aid.
in suitcase to keep in room,
bandaids, Motrin, decongestant, benedryl, Imitrex.
Anything else I can buy if we really needed it because we are in the middle of civilization not the wild. and I'm not taking up room to save $5 if and when I might need something else.
In all my trips places I really have never needed anything else.
