Quick Facts
  • If you have been diagnosed with a food allergy, your doctor or allergist will prescribe an epinephrine auto-injector.
  • Epinephrine is the drug form of a hormone (adrenaline) that the body produces on its own. It is the only drug that can reverse symptoms of anaphylaxis. Epinephrine rarely causes harm, even if given when not needed.
  • There are two types of auto-injectors in Canada: EpiPen® and ALLERJECT®).
  • You can buy an auto-injector without a prescription in Canada.

If someone is having an anaphylactic reaction, follow these 5 emergency steps:

  1. Give epinephrine (e.g. EpiPen®, ALLERJECT®) at the first sign of a known or suspected anaphylactic reaction.
  2. Call 9-1-1 or your local emergency medical services and tell them that someone is having an anaphylactic reaction.
  3. Give a second dose of epinephrine as early as 5 minutes after the first dose if there is no improvement in symptoms.
  4. Go to the nearest hospital right away (ideally by ambulance), even if symptoms are mild or have stopped. The reaction could get worse or come back.
  5. Call emergency contact persons (e.g., parent, guardian, spouse).

Don’t delay in giving epinephrine! That’s one of the most common mistakes people make during anaphylactic reactions. Epinephrine is safe, and it can save a life. Don’t hesitate to use it.

Body position

Keep in mind the following body positions while giving epinephrine and waiting for emergency care to arrive.

  • Place the person on their back with their legs raised.
  • If the person is vomiting, place them on their side so that their airway is clear and they do not choke on vomit.
  • Remember: standing suddenly can lead to severe complications, even death.

Teaching children
  • You are a role model for your child. As your child grows and learns to carry their own auto-injector, they will remember your example. Learn more.

Emerging Allergen Reporting Tool

If your child has had a reaction in the last 12 months to a food other than a priority allergen, participate in an important research survey. Your participation will help researchers, and advocacy groups like ours, better understand emerging allergens.
