There actually is a BIG difference on medicine efficacy based on how hot it gets. So, for all the states getting >90 degrees on a regular bases, the recommendation was to change the meds out frequently.
I wonder if the military has any MILSPEC ratings for FAKs at high temperatures?
A week or two ago my parents measured 122F passing through Tucson AZ, which translates to well over 150F in a parked car trunk and who-knows-what in the passenger areas. It seems pointless to store Neosporin, antiseptic wipes, etc, in a car FAK in such an environment. Perhaps a belly-pack so the thermally "delicate" things can be brought inside to work every day?
