# Allergy Care

> ⚠️ **Ask your doctor or health care professional. This information is AI generated for education and NOT medical advice.**

An allergy is an immune system reaction to a substance (allergen) that
is normally harmless, ranging from mild irritation to a severe,
life-threatening reaction (anaphylaxis).

## Common symptoms

Sneezing, itchy or watery eyes, rash or hives, swelling, digestive upset
(for food allergies), and — in severe reactions — difficulty breathing,
swelling of the throat, or a drop in blood pressure.

## General self-care measures

- Identify and avoid known triggers where possible.
- Take prescribed antihistamines or other medication as directed for
  known allergies.
- Carry an adrenaline auto-injector if prescribed for severe allergy
  risk, and know how and when to use it.
- Keep a written action plan for known severe allergies, shared with
  people around you.

## When to seek medical attention

- Signs of anaphylaxis (difficulty breathing, swelling of the face/
  throat, rapid pulse, dizziness, or fainting) — this is a medical
  emergency; use an adrenaline auto-injector if available and call
  emergency services immediately. See [[urgent-emergency-care]].
- New or worsening allergic reactions.
- Uncertainty about what's causing a reaction.

## Common pitfalls

- **Assuming a past mild reaction guarantees future reactions will also
  be mild** — allergy severity can change and escalate on
  re-exposure.
- **Not carrying a prescribed adrenaline auto-injector** — even for
  someone who's "never needed it before"; severe reactions can occur
  unpredictably.
- **Delaying using an adrenaline auto-injector out of uncertainty** —
  when anaphylaxis is suspected, using it promptly and then seeking
  emergency care is the safer default.
