Anaphylaxis is a life-threatening allergic reaction triggered by some serious food allergies. Many Canadian adults and children are at risk of this reaction.

Symptoms of a severe allergic reaction can start within minutes of coming into contact with an allergen, and can include any of the following:

  • Skin: itching, redness, swelling, hives, rash
  • Airway: trouble breathing, swallowing, speaking, coughing, nasal congestion or hay fever-like symptoms
  • Stomach: nausea, pain, vomiting, diarrhea
  • Heart: weak pulse, pale/blue colour, weak, lightheaded, fainting, shock
  • Other: anxiety, sense of doom, loss of consciousness

If you are concerned that you or your child may have a severe food allergy, talk to your doctor for more information.
