ANAPHYLAXIS
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
Reference: Anaphylaxis Canada (2013)

WHAT IS ANAPHYLAXIS?
Occurs when a person is exposed to an allergen causing a severe, life-threatening allergic response
Reactions occur within minutes or, more rarely, up to a few hours after exposure
Reference: Anaphylaxis Canada (2013)3
COMMON SYMPTOMS
Skin – hives , swelling, itching, warmth, redness, rash
Respiratory (breathing) – wheezing, shortness of breath, throat tightness, cough, hoarse voice, chest pain/tightness, nasal congestion or hay fever-like symptoms (runny itchy nose and watery eyes, sneezing), trouble swallowing
Reference: Anaphylaxis Canada (2013)

COMMON SYMPTOMS
Gastrointestinal (stomach): nausea, pain/cramps, vomiting, diarrhea
Cardiovascular (heart): pale/blue colour, weak pulse, passing out, dizzy/lightheaded, shock
Other: anxiety, feeling of “impending doom”, headache, uterine cramps in females, metallic taste
Reference: Anaphylaxis Canada (2013)

Trouble breathing caused by airway swelling
A drop in blood pressure causing dizziness, light-headedness, feeling faint or weak, or passing out

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?
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
Reference: BC Anaphylactic and Child Safety Framework (2007)
12
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
13
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.

WHAT TO DO AFTER GIVING EPINEPHERINE
• Have students lie still on their backs with their feet higher than their heads
• If vomiting, have the students lie on their sides to prevent choking
• If breathing is difficult, have the students sit up
• Loosen tight clothing and cover students with blanket
• Don’t give anything to drink
• Send auto-injector with students to hospital
Reference: Anaphylaxis Canada (2013)
CONCLUSION:FOLLOW THE THREE A’S
Awareness Know the triggers Know the emergency plan and how to
administer epinephrine via the auto-injector
