First aid kit? Never thought of a first aid kit but I do carry certain medications, if I remember to bring them. Does a peanut butter and jelly and apple butter sandwich count?
Apparently there was a form of tetracycline (antibiotic) that, when degraded, was associated with renal tubular damage. But that form of the drug is no longer marketed in the US.
I will continue to carry my left over surgery/labor drugs in my ski kit.... Rather have them than not!
I bet those are awesome!
