I work for a national company as an independent contractor, usually on my own in the field or wilderness, not on an ambulance. My medical direction is non-existent when out on a job. My question: Is there a substitute for an EpiPen that may make a difference when a pt is having a severe allergic reaction in a rural or wilderness environment? I have seen some general references about using Benadryl in these situations and want to see if those of you who know much more than me agree. If so, what would an appropriate adult dose be in an emergency situation? If Benadryl is not an appropriate option, is there any other OTC product that can help? Thank you in advance.
