Anaphylaxis: How to Recognize It and What to Do

Anaphylaxis is an allergic reaction on overdrive. It is rapid, severe, and potentially fatal. It doesn't always look like the movies (throat closing immediately). Sometimes it's subtle at first, then crashes fast. Knowing the signs can save a life.

Recognizing the Signs (FAST)

Anaphylaxis typically involves two or more body systems (e.g., skin + stomach). Watch for:

• Skin: Hives, generalized redness, itching.
• Breathing: Wheezing, shortness of breath, cough, hoarse voice.
• Stomach: Persistent vomiting, severe cramping.
• Circulation: Pale/blue skin, weak pulse, dizziness, fainting (drop in blood pressure).

What to Do: ACT NOW

If you suspect anaphylaxis, follow these steps immediately. Do not wait to see if it "gets better."

1. Inject Epinephrine Immediately: This is the only medication that reverses anaphylaxis. Antihistamines (like Benadryl) do NOT stop anaphylaxis; they only treat hives.
2. Call Emergency Services (911): Tell the dispatcher "Anaphylaxis."
3. Lay the Person Flat: Do not let them stand or walk, as this can cause their blood pressure to bottom out and lead to cardiac arrest. If they are vomiting, turn them on their side.
4. Prepare a Second Dose: If symptoms don't improve after 5-15 minutes, a second injection may be needed.

Prevention

The only way to prevent anaphylaxis is strict avoidance of the allergen. It is not a matter of "just a little bit." For an allergic person, a microscopic amount is a poison.
