Hey, as to definition of anaphylaxis and when/if to use Epi, I VERY recently had allergist flat out tell us that "only hives" would require that breathing be affected in order to need Epi.
Now, mind you, these were hives that were not just localized due to contact (systemic -- trunk, inside elbows and back of knees, face around mouth) -- this was recent contact that became ingestion and was systemic hives for the child with the lifelong history of severe reactions. Had I been the PIC (parent in charge) at the time, I would have Epi'd-and-911'd. The child and PIC chose route of Benadryl with wait-and-see -- which is against most of what we've been told to do previously by this and other allergists.
I'm weary of the mixed messages and the "rules" that seem to change with the tides.
Weary.
And more importantly, confused. Even after all these years.
Sorry, veering off topic . . . .
