Survival for what disaster? Hurricane is different than getting lost in the woods. We had a premade kit at one point that was given to is for free and the majority if the medicine wound up getting years expired and it wasn’t usually the brands you like anyway.
I think it’s best to keep a survival kit full of the products you keep on hand anyway and use the stuff up and replace as you go and not have a separate tube of neosporin and bottle of Advil. Your survival kit is your every day health kit. If you leave for a week or have a natural disaster coming you can load up on water, packaged food, and dram out specific amounts if the drugs you might need.
