I am not "giving medical advice", but I am a physician in real life. Please don't spam PM's at me.
With regard to epinephrine: I can and do give out prescriptions for epi-pens almost freely. I have had to give injections of epinephrine myself to people having anaphylactic shock, and can agree it's scary as heck to see someone crumpling in front of you quickly. However, epinephrine if given in the wrong circumstance can be pretty harmful. I saw a young lady have a heart attack because she received too much epinephrine, once "in the field" and then again by a well meaning paramedic who figured two doses wouldn't hurt, I guess, or didn't believe she had the first. Anyway, it is a powerful drug. I hesitate to say that every bee keeper should have an epipen/epipen jr on hand, as indiscriminate use is very harmful. However, it DOES seem reasonable to me having seen all sides of this coin.
I am a new beekeeper, actually don't even have my bees yet, but I will have an epipen and epipen jr on hand. I have a wife a 3 year old son who have no known allergy to bee stings, but I am also in a rural area. I don't know what the cost is, but I will likely buy these outright without insurance per se, and I think it will be about 50 bucks. If I replace them twice yearly, $100 ain't bad to avoid seeing someone crumple in front of me while I think "Crap, I know how to fix this"
Oh, and I have seen people who would have died within minutes (less than 20 minutes) without epinephrine....and people often hesitate to call EMS until they KNOW there is a problem, and not every EMS vehicle etc has epi.
