Wow! So glad she is OK. Sounds like she did things well, but curious why not call 911?
While all anaphylaxis is serious, I guess there's still a range. I went jogging with a friend who was stung by something a mile into our run. Within 2 minutes she was unconscious and swelled up like the StayPuft man. That's a 911 call. Dd gets hives, itchy tongue, runny nose, which completely resolves with the epi. With her sisters driving her, and an extra epi with her, I'm comfortable they way they did it.
I was also happy the UC doc asked dd if she needed a new Rx for another epi.
All good points to think about, though. I'll have to talk to her and the sisters about when 911 or at least going to a hospital ER would be a better idea.
