naphylaxis, a severe allergic reaction to food and insects, can involve several body systems and be life-threatening, putting as many as 600,000 Canadians at risk. An estimated 2 to 4% of children, and up to 6% age three and under, may be at risk of allergic reactions to foods including peanuts, fish, milk, egg, wheat and soy. Most victims of fatal allergic reactions are adolescents and young adults; four out of six fatalities occur at school.
Recognition + response
Anaphylactic symptoms can include hives, itching or rash; swelling of lips, tongue, throat or face; vomiting or nausea, diarrhea or stomach cramps. Respiratory distresses that occur are coughing, wheezing, choking, change in voice, itchy nose, watery eyes, sneezing, trouble swallowing and difficulty breathing. Effects to the cardiovascular system are exhibited with a pale/blue color, weak pulse, passing out, dizziness and shock. Other known symptoms are anxiety, feeling of ‘impending doom’ and headache.
Strict allergen avoidance is the prevention; an injection of epinephrine, the treatment. Always carry an epinephrine auto-injector and wear a medical ID bracelet.
An anaphylactic reaction often occurs within seconds of exposure but symptoms can be delayed up to two hours. Allergic reactions are unpredictable, so take any symptoms in an at-risk person very seriously. Administer epinephrine immediately! |

It’s easier to stop a life-threatening allergic reaction in its early stages. Untreated anaphylaxis, or a delay in recognizing severe symptoms and administering epinephrine, can lead to a loss of consciousness, coma or death.
Ensure your child’s school has an allergen prevention policy that includes: trained staff; minimized risk exposure; and the availability of life-saving medications for at-risk students. Your Rexall pharmacist can provide training on the proper use of the epinephrine auto-injector, educational materials and help with a prevention plan. H&L |
