Every allergic reaction has the possibility of
developing into a life-threatening and potentially
fatal anaphylactic reaction. This can occur within
minutes of exposure to the allergen.

Allergy Information
 Food Allergy in children has risen 18% in 10 years.
 Hospitalization due to food allergies has tripled in 10 years.
 Individuals with asthma in addition to food allergies may be at
increased risk for having a life-threatening anaphylactic reaction.
 Teens with food allergy and asthma appear to be at the highest risk for
a reaction, because they are more likely to take risks when away from
home, are less likely to carry medications, and may ignore or not
recognize symptoms.
 16% to 18% of children with food allergy experience a reaction at school
with 79% of these reactions having occurred in the classroom, only 12%
in the cafeteria.

Missouri Allergy Prevalence
2006-2007:
466 Districts, 823,293 Students
2008-2009:
478 Districts, 863,943 Students
 Students with life-threatening
insect sting allergies: 2,561
latex allergies: 430
food allergies: 4,617
insect sting allergies: 3,303
latex allergies: 653
food allergies: 8,872

Latex Allergies
 Latex products are a common source of allergic type reactions.
 Two common types of reactions include:
 Contact dermatitis (skin rash) - can occur on any part of the body
that has contact with latex products, usually after 12-36 hours.
 Immediate allergic reactions - are potentially the most serious form
of allergic reactions to latex products. Rarely, exposure can lead to
anaphylaxis depending on the amount of latex allergen that they are
exposed to and their degree of sensitivity.
 Latex exposure should be avoided by students and staff at risk for
anaphylaxis. Since the reactions caused by latex vary, each
student at risk should be evaluated by a trained medical
provider, preferably an allergist.

Insect Sting Allergies
 Insect allergy is an underreported event that occurs every year to
many adults and children.
 Most stings are caused by yellow jackets, paper wasps, and
hornets.
 Some students have true allergies to insect stings that can lead to
life-threatening systemic reactions.
 Prompt identification of the insect and timely management of
the reaction are needed.
 Insect avoidance is advised for students and staff at risk for
anaphylaxis.
 Some precautions schools should follow include:
1) insect nests should be removed on or near school property,
2) garbage should be properly stored in well-covered containers, and
3) eating areas should be restricted to inside school buildings for
students and staff at risk.

Food Allergy Overview
 Approximately five to six
percent of the pediatric
population has had an
occurrence of food allergy
with eight foods
accounting for 90% of
allergic reactions.
 Currently there is no cure
for food allergies and strict
avoidance is the only way
to prevent a reaction.

Food Allergy
 Food allergy is an exaggerated response by the immune system to
a food that the body mistakenly identifies as being harmful.
 Once the immune system decides that a particular food is
harmful, it produces specific antibodies to that particular food.
 The next time the individual eats that food, the immune system
releases moderate to massive amounts of chemicals, including
histamine, to protect the body.
 These chemicals trigger a cascade of allergic symptoms that can
affect the respiratory system, gastrointestinal tract, skin, and
cardiovascular system.
 A reaction can occur within minutes to hours after ingestion.
 Symptoms can be mild to life-threatening (anaphylaxis).
 The specific symptoms that the student will experience depend
on the location in the body in which the histamine is released.

Signs and Symptoms
 Symptoms usually appear within minutes and can occur
within hours after exposure to the food allergen.
 The student can also face a “rebound effect” of the
symptoms. This means that they may respond initially to
treatment but experience a resurgence of symptoms hours
later - this is called a biphasic reaction.
 It is vital to observe students who have been exposed to an
allergen over a period of time to ensure their safety in the
event of a rebound.
 A recent study of adolescents showed that students with
peanut and nut allergies who also have asthma may
experience a more severe reaction to the allergen.

Signs and Symptoms
 Hives
 Itching (of any part of
body)
 Swelling (of any body
parts)
 Red, watery eyes
 Runny nose
 Vomiting
 Diarrhea
 Stomach cramps
 Change of voice
 Coughing
 Wheezing
 Throat tightness or closing
 Difficulty swallowing
 Difficulty breathing
 Sense of doom
 Dizziness
 Fainting or loss of
consciousness
 Change of skin color

Careful planning and prevention can greatly
reduce the risk of students experiencing
anaphylaxis, or a life-threatening allergic
reaction at school

What We Can Do
 There is no cure for allergies or anaphylaxis.
 But there are steps we can take:
 To prevent exposure,
 To recognize when an exposure has occurred,
and
 To respond quickly and effectively.

Prevention
 Avoidance of exposure to allergens is the key to
preventing an allergic reaction.
 The school nurse will develop an Individualized Healthcare
Plan (IHP) based on each child’s unique needs and
treatment.
 The school nurse will develop an Emergency Action Plan
(EAP).
 The IHP will provide specific prevention steps for the
individual child and the EAP will provide student specific
symptoms to observe.
 Students with food allergies and anaphylaxis must not be
excluded from school activities and the IHP and EAP will
provide steps to keep the student safe.

Prevention
 Do not allow food in instructional areas unless approved by
parent of child with food allergy.
 Consider art and science materials, including pet foods.
 Promote hand washing before and after eating.
 Read food labels every time food is served.
 Always contact the parent of a child with an allergy if there
is any question about safety - take no chances!
 Consider talking with the parent of the child with an
allergy to send home a letter to parents in the class.
 Be sure to take Emergency Action Plan and Medication on
field trips.

Recognition
 Know the signs and symptoms specific to each child as
listed on their Emergency Action Plan (EAP).
 Do not ignore odd symptoms or behaviors that may
indicate an allergic reaction.
 Always consider possible allergy if any different symptoms
appear in a child with allergies.
 Food is the leading cause of anaphylaxis in children.
 Children who have asthma and food allergies are at a
greater risk for anaphylaxis and may often react more
quickly requiring aggressive and prompt treatment.

Steps to Take
 If a student displays signs and symptoms of an allergic
reaction and/or reports an exposure to their allergen,
school personnel should immediately implement the
school’s policy on allergy anaphylaxis which should require
that immediate action be taken:
 Notify the school nurse (if available) and initiate the
Emergency Action Plan;
 Locate the student’s epinephrine immediately;
 Implement the student’s Emergency Action Plan; including
timely administration of epinephrine if needed, and
 Call 911 if epinephrine has been administered.

Emergency Medication
 Epinephrine or Epi Pen
 Many ambulances don’t carry epinephrine – the school may
need to request “Advanced Life Support” for EMS to respond
with epinephrine.
 All students will require assistance with the EpiPen
administration - symptoms of anaphylaxis will affect the
ability of the child to self administer.

Act Quickly! Do Not Delay!
 Epinephrine is the medication of choice for the treatment
of acute anaphylaxis.
 Delay of or failure to administer Epinephrine may
contribute to a fatal outcome.
 When in doubt, use the EpiPen.
 The side effects of the EpiPen could include fast heart beat,
jittery feeling, and other cardiovascular symptoms.
 The life-saving benefit of Epinephrine outweighs the risks
of side effects in an anaphylactic reaction.
 Call 911 anytime Epinephrine is administered.

Other Medication for use with
Allergic Reactions
 Antihistamine –
 Diphenhydramine hydrochloride - Brand name
includes: Benadryl
 Cetirizine – Brand name includes: Zyrtec
 May cause drowsiness, nausea, and dryness of the
mouth.
 NOTE: Antihistamines should not be the only
medication given in anaphylaxis since epinephrine is the
drug of choice. There is no contraindication to give
epinephrine for anaphylaxis along with an oral
antihistamine.
