Anaphylaxis is a severe, allergic reaction to a chemical that has become an allergen. It occurs rapidly and causes a life-threatening response involving the whole body. Anaphylaxis may occur on subsequent exposures to a chemical or substance that the immune system has become sensitized to after initial exposure.

Anaphylaxis affects multiple body systems including the skin, upper and lower respiratory, gastro-intestinal and cardiovascular. Upon a severe allergic reaction, tissues in different parts of the body release histamine and other substances. This causes the airways to tighten and leads to other symptoms. An anaphylactic reaction can progress in severity very quickly and without the immediate administration of epinephrine, can be deathly.

The Canadian Anaphylaxis Registry is for people who are allergic to food, insect stings, medication, latex or exercise. The specific information collected will allow the registry to provide those who suffer from severe allergies with relevant clinical and educational updates as well as product recalls. The registry also provides statistical data for research studies, advocacy and fund-raising.
