• Allergic Reaction/Anaphylaxis

    What is Anaphylaxis?

    Anaphylaxis is a life-threatening allergic reaction that can cause shock and affect the person’s ability to breathe. A person with anaphylaxis may have swelling of the face, neck, tongue or lips, trouble breathing, shock or a change in responsiveness.

    What are types of things that can trigger anaphylaxis?

    Anaphylaxis is a severe, life-threatening allergic reaction that can be triggered by many things including venomous stings, certain foods (like peanuts, tree nuts, shellfish, milk, eggs, soy and wheel), animal dander, plant pollen, latex or certain medications (like penicillin and sulfa drugs).

    Allergic Reaction FAQs

    What is the difference between anaphylaxis and an allergic reaction?

    An allergic reaction can range from mild to severe. A person with a mild to moderate allergic reaction may develop a skin rash; a stuffy nose; red, watery eyes; abdominal cramps or nausea. The skin or body area in contact with the allergen may swell, turn red and may have hives.

    Anaphylaxis is a life-threatening allergic reaction that can cause shock and affect the person’s ability to breathe. A person with anaphylaxis may have swelling of the face, neck, tongue or lips, trouble breathing, shock or a change in responsiveness.

    What is epinephrine?

    Epinephrine is a drug that slows or stops the effects of anaphylaxis. If a person has a known allergy that could lead to anaphylaxis, they may carry an epinephrine auto-injector (a syringe system, available by prescription only, containing a single dose administered as an injection).

    Is an epinephrine auto-injector used for any allergic reaction?

    No. It is used only for anaphylaxis. This medication is prescribed for a person who is known to have an allergy that could lead to anaphylaxis.

    What if I’m alone with the person in anaphylaxis? Should I care first or call 9-1-1 first?

    If you are alone, assist them with administering the medication and then call 9-1-1. While you wait for help to arrive, help the person sit in a comfortable position or have the person lie down if they are showing signs of shock.

    What types of things can trigger anaphylaxis?

    Anaphylaxis is a severe, life-threatening allergic reaction that can be triggered by many things including venomous insect stings, certain foods (like peanuts, tree nuts, shellfish, milk, eggs, soy and wheat), animal dander, plant pollen, latex or certain medications (like penicillin and sulfa drugs).

    What is shock?

    Shock is a progressive, life-threatening condition in which the body does not get enough oxygen-rich blood often due to disturbed blood flow. As a result, organs and body systems begin to fail.

    Signs and symptoms include:

    • Rapid, weak heartbeat
    • Rapid breathing
    • Pale, gray, or cool moist skin
    • Altered level of responsiveness
    • Excessive thirst
