WHAT IS AN ALLERGY?

Allergies occur when the immune system becomes

unusually sensitive and overreacts to common

substances that are normally harmless. Examples are:

Foods – eggs, milk, peanuts, tree nuts, seafood, wheat, soy, sesame seeds, sulphites and mustard

Insect bites – bees, wasps, hornets and some ants

Medications – penicillin, sulfa drugs

Exercise

Latex – gloves/medical devices

Reactions occur within minutes or, more rarely, up to a few hours after exposure

Increased independence

Increased risk taking Eating unsafe food and eating out Not carrying auto injector

Not telling friends

Not wearing a medical alert IDReference: Allergy Safe Communities (2013)

WHY ARE TEENS AT HIGHER RISK?

Page 11: ANAPHYLAXIS. WHAT IS AN ALLERGY? Allergies occur when the immune system becomes unusually sensitive and overreacts to common substances that are normally

PREVENTION = HAVING A PLAN

Ensure the medical alert list is up-to-date and familiarize yourself with students who have medical conditions and allergies

Review emergency care plans for each student

Note where auto-injectors are stored for each student. Ensure auto-injectors are immediately available

Recognize allergy sources and triggers

Know when and how to administer the auto-injector

Prepare for outdoor and off school ground activities

Encourage students to wear medical alert identification 11

WHAT SHOULD I DO?

1. Administer single dose auto-injector2. Call 9113. Notify parent/guardian4. Administer second auto-injector in 5 to 15 minutes after first dose is given IF symptoms do not improve or if symptoms recur 5. Have ambulance transport student to hospital

*Epinephrine is the only way to reverse the effects of anaphylaxis. Give ASAP

**Remember, the epinephrine may only last for 15 minutes, call 911 after administering auto-injector

WHAT SHOULD I DO?

When in doubt, administer epinephrine. Symptoms of anaphylaxis can be as simple as redness or as severe as cardiac arrest.

If a person says they are having a reaction it is important to believe them, and immediately administer epinephrine regardless of the symptoms present

Antihistamines and asthma medication must not be given as first line treatment for anaphylaxis

WHAT IS AN EPINEPHRINE AUTO-INJECTOR?

An auto-injector is an easy way to give epinephrine to someone having an allergic reaction

There are three auto-injectors available in BC: EpiPen®

AllerjectTM

Twinject®

*Please note that Twinject® is currently not available on the market.
