When a person has an allergy, he or she experiences an immune response to a substance that is usually not harmful. An allergy emergency may occur if a person is exposed to this allergen. An allergic reaction may become severe if not treated in a timely manner.
People may be allergic to a variety of different things such as:
|Animals (i.e., cats, dogs)|
|Medication (i.e., penicillin)|
|Pollen, dust, mold|
|Specific plants / chemicals in plants|
Signs and Symptoms:
|Nausea, vomiting, diarrhea (stomach pain)|
|Rash, hives, redness|
|Signs of shock|
|Stuffy nose, sneezing|
|Swelling of the tongue and face|
This is a severe, life-threatening allergic reaction. It occurs suddenly, and within seconds or minutes after contact with the allergen.
A reaction of troubled breathing can cause obstructions in the airway and even lead to shock. Anaphylaxis requires immediate medical treatment, including the epinephrine injection and a trip to the hospital.
