It treats shock. (Source: I have a bee allergy. Tibby has everything allergies. We've been advised what to do in the event of anaphylaxis. The answer is 100% epinephrine every time. In fact, they say potential side effects are worth it.) Long story short, she has options when it comes to antihistamines. There are few options when it comes to anaphylaxis. Epi pens are the main treatment. That said, she clearly didn't go into shock, so she shouldn't be too worried about finding an option for it.
