A severe life threatening allergic reaction is called anaphylaxis.
Symptoms of anaphylaxis may include itching and hives over large areas
of the body, swelling in the throat or tongue, difficulty breathing,
dizziness, stomach cramps, nausea or diarrhea.
In severe cases, a rapid fall in blood pressure may result in shock
and loss of consciousness. Anaphylaxis is a medical emergency, and may
be fatal.
Epinephrine is the gold standard of treatment in the event of a severe
reaction. It is available by prescription as an auto injector.
Food is the leading cause of anaphylaxis in children.
Statistics:
Penicillin is a common cause of drug allergy. Anaphylactic reactions
to penicillin cause 400 deaths.
Food-related anaphylaxis causes approximately 30.000 emergency department
visits and 150 deaths each year.
A severe allergic reaction known as anaphylaxis occurs in 0.5 to 5%
of the U.S. population as a result of insect stings.
Approximately 220 cases of anaphylaxis and 3 deaths per year are due
to latex allergy.
