Allergic Reactions & Anaphylaxis — First Aid
For educational purposes only — not medical advice. Always consult a qualified healthcare provider. For adults 18+.
Most allergic reactions are mild — but anaphylaxis is a fast, life-threatening emergency, and knowing the signs saves lives. This guide explains how to tell them apart and respond without panic.
The difference between a mild allergic reaction and anaphylaxis, the warning signs to never ignore, how an adrenaline auto-injector (such as an EpiPen) is used in an emergency, what to do while help arrives, and why anaphylaxis always means calling 911.

For educational purposes only
This guide is educational information about first aid and home safety — it is not medical advice, and it is not a substitute for professional medical care or hands-on, certified first-aid and CPR training. It does not diagnose, treat, or replace emergency care. Knowing first aid saves lives, but reading about it is not the same as being trained — consider a certified course (for example through the Red Cross or St John Ambulance). In any real emergency — including severe bleeding, a serious allergic reaction, a seizure, suspected poisoning, or heat stroke — call 911 (or your local emergency number) immediately and follow the dispatcher's instructions.
