Not a debate just an observation from someone who has been in an anaphylactic shock state 5 times because of cross contamination of food with sea food.
The only time epinephrine was ever given my tongue was swollen. Once the epinephrine was injected my heart raced so fast you could see it beating through my clothes and I began to shake uncontrollably and I was freezing cold.
The other times an injection of Benadryl and have been fine. I also carry Benadryl pills with me and if I start to feel hives I can take that and it usually stops a reaction.
