Allergic Reaction, Severe
What is a severe allergic reaction?
A severe allergic reaction is called an anaphylactic
reaction. It is an immediate, severe reaction to a bee
sting, drug, food, or other item. The symptoms begin within
30 to 60 minutes and are:
- wheezing, croupy cough, or trouble breathing
- tightness in the chest or throat (voice may change)
- dizziness or passing out (skin may change color)
- swelling of lips, tongue, or throat
- widespread hives, swelling, or itching. (If these
symptoms occur without the symptoms listed above, your
child is probably not having an anaphylactic reaction.
However, hives, swelling, or itching often occur with
other serious symptoms when a child has a severe allergic
reaction.)
- vomiting, diarrhea, or stomach cramps.
What should I do if my child has a severe allergic reaction?
- Call 911 IMMEDIATELY.
Call the rescue squad (911) if your child is having
trouble breathing or passes out. Have your child lie
down with the feet elevated to prevent shock.
- Give epinephrine
If you have a emergency kit with prescription
epinephrine (such as EpiPen), give a shot of it to your
child immediately. It can save your child's life.
Inject it into the muscle or fat layer of the outer part
of the upper thigh.
Don't hesitate to give epinephrine. If there is any
possibility your child is having symptoms of an
anaphylactic reaction, give the epinephrine immediately.
In addition, if your child had a life-threatening
reaction in the past and now has been re-exposed to the
same allergic substance (for example, food, or bee
sting), give the epinephrine BEFORE your child develops
symptoms. Epinephrine will not hurt your child even if
he is not having an allergic reaction and it could save
his or her life.
- Give an antihistamine
If you have Benadryl at home, give it. If not, check if
you have another antihistamine or cold medicine that has
an antihistamine in it. If you do, give one dose
immediately in addition to the shot of epinephrine.
- Treat stings
If a bee stinger is left in the skin, remove it. Do
this by scraping the stinger off with a knife blade or
credit card rather than by squeezing it.
What can I do to prevent an allergic reaction?
The only way to prevent a reaction is to AVOID contact with
the food, drug, or other item causing the problem.
All children with anaphylactic reactions need to be evaluated
later by an allergist. For bee sting reactions, desensitization
is helpful. Since the reactions can be fatal, you should keep
emergency kits containing epinephrine at home, school, and in a
backpack (or fanny pack). You will need a prescription. The
allergist or your child's usual health care provider may
prescribe epinephrine. In case of a severe reaction,
epinephrine is need immediately.
Educate others about your child's allergy (what your child
needs to avoid, the symptoms of a reaction, emergency
treatment, reading food labels, etc.).
Also, your child should have a medical ID necklace or
bracelet that tells the insect, drug, or food allergy. Some
ID necklaces and bracelets can be found in pharmacies.
