Lessons From a Teen Food Allergy Tragedy

AL: There’s some perception that there’s danger to epinephrine. You may be uncomfortable, you’re shaking, or your heart’s flying .…

SW: Those are generally non-dangerous side effects of epinephrine: increased heart rate, the tremulousness, the anxiety. Used within reasonable amount, like one or two injections, there is no downside. It is not a dangerous drug used as a treatment for anaphylaxis, and that’s what we teach people: no downside.

AL: What are the signs that it’s time to inject?

SW: There are signs where it’s undebatable: dizziness, shortness of breath, difficulty swallowing, loss of consciousness, drop in blood pressure, tongue swelling, severe abdominal pain, profuse vomiting. But it’s hard to use those signs of fairly advanced symptoms to say at the start of a reaction that it won’t progress. The idea is to prevent those symptoms from happening.

AL: But there is a tendency to wait for significant symptoms before using the auto-injector.

SW: I know. Yet, everything that you read in the medical literature points to too little epinephrine being given – by patients, by the community, by the emergency room. Still, there’s no question that there’s a trend that people do want this mild-severe type of spectrum where antihistamine is enough.

But there’s a downside to that. And young Natalie represents is just one of them. Somebody can always say, “The signs must have been there, somebody missed them” – well, people don’t judge severity very well; it’s not that straightforward. Most of us [allergists] are fairly convinced that we don’t know that every mild reaction stays a mild reaction, and that’s the danger.

AL: Is there anything else you would add to this discussion?  

SW: As sad and tragic as Natalie’s death is, I think it reinforces really basic principles about treatment, about how reactions can advance very quickly and you’re not aware of it. Now that there is much discussion around this issue of antihistamine use for mild reactions, which many of us are uncomfortable with, I think this reinforces why it’s not a good idea.

[In Natalie’s case], even if they’d used epinephrine early, you have no idea what the outcome would have been. One cannot go back in time and address those issues – you can only try to stack the deck in your favor in future situations.
