What to Do when an Allergic Reaction Occurs

If you exhibit signs of an allergic reaction, go to the A&E department immediately or call for an ambulance.

An allergy is the immune system's overactive response when exposed to an allergen. Common allergens include foods, drugs and dust.

Signs and symptoms of an allergy include itchy and watery eyes, vomiting, nasal congestion, itchy rashes or hives, and abdominal pain.

Common food allergens are peanuts, shellfish, milk, eggs, fish and corn.

If you think someone is experiencing an allergic reaction,

  1. Call an ambulance
  2. Use an EpiPen (check if the patient has one)
  3. Place the patient in a position they are most comfortable in
  4. Loosen tight clothing and cover the patient with a blanket
  5. Give CPR if there are no signs of breathing, coughing or movement

Note: Do not give the patient anything to drink. If there's vomiting or bleeding from the mouth, turn the patient on their side to prevent choking.
