Yes you could (assuming no allergies or gi bleeds) and just inform the incoming EMTs
I'm getting up there in age and that is presumably something that I should learn about myself...
Don’t want to suggest you do something and end up with anaphylaxis.
A bunch of people don’t even have a primary care provider now.
It’s not out of legal concern. I do not know how one tests an allergy, I’m not an MD..
Im sure google could suggest some options or maybe a test.
