Try this analogy: Anaphylaxis is a serious allergic reaction that can affect breathing, circulation, and other body systems.
Ask your child: If someone may be having a serious allergic reaction, what trusted adult should you tell immediately?
Common mix-up: Anaphylaxis can become life-threatening quickly. Follow the person's emergency plan, get trained adult help, and call 9-1-1; this content is for awareness, not a substitute for medical training.
