Severe Allergic Reaction in Cabo — Anaphylaxis Recognition and Response

Severe allergic reactions can happen on vacation from foods you don’t normally eat, medications, insect stings or unknown triggers. Anaphylaxis is a medical emergency that requires immediate epinephrine and ER care.

Recognize anaphylaxis

Difficulty breathing, swelling of face/lips/tongue, tightness in throat, hives spreading, severe vomiting/diarrhea, rapid heartbeat, fainting, sense of doom. Often multiple symptoms together within minutes of exposure.

Use epinephrine immediately if available

If you carry an EpiPen (or generic auto-injector), use it at the first sign. Inject into outer thigh. Even through clothing is okay. After injection, call for emergency help — epinephrine works for ~15 minutes; you need ER backup.

If no EpiPen available

Call 911 and our 24/7 line. Note exposure (food, sting, etc.). Move patient to safety. Position upright if breathing trouble, lying down with legs up if fainting. Do not give anything by mouth if airway compromised.

At the hospital

IV epinephrine, antihistamines, steroids, breathing support if needed. Observation for biphasic reaction (recurrence 4-24 hours later). Sometimes admission.

After recovery

Identify trigger if possible. Get an EpiPen prescription for the rest of your trip and back home. Notify your travel insurance.
