Do you know the signs and symptoms of anaphylaxis?

Anaphylaxis (an-a-fi-lax-is) is the medical term for a potentially life-threatening allergic reaction. It can occur within minutes after exposure to an allergen . That’s why it’s important to know what symptoms to look for:

Why is it important to know these signs and symptoms?

Anaphylaxis is unpredictable—a mild allergic reaction one time can be life-threatening or severe the next. For example, someone who has a peanut allergy may accidentally eat a peanut and feel tingling lips and watery eyes that eventually go away. However, if the same person is accidentally exposed to a peanut on a different occasion, it could cause difficulty breathing, weak pulse, shortness of breath, fainting and hives that may quickly become life-threatening. Both are instances of anaphylaxis, but the severity, progression, symptoms and duration of the symptoms are inconsistent and unpredictable.

Is shock (sometimes called anaphylactic shock) a symptom of anaphylaxis?

Shock is just one of the many possible symptoms of anaphylaxis. It occurs when there is inadequate blood flow to critical organs of the body during anaphylaxis. However, shock may not be one of the symptoms a person experiences during anaphylaxis. More than half of all patients in a 10-year study showed no signs of shock during anaphylaxis. That’s why the term anaphylaxis is not interchangeable with the term anaphylactic shock—the first term encompasses all possible symptoms of a life-threatening allergic reaction.

Vigilance is essential

Because of this unpredictability, it’s crucial for parents and caregivers of children living with potentially life-threatening, or severe, allergies—as well as adults with severe allergies—to be vigilant about any type of allergic reaction ranging from mild to severe. Talk to a healthcare professional about how to identify the signs and symptoms of a life-threatening allergic emergency (anaphylaxis).

When to use EPIPEN® (epinephrine injection, USP) or EPIPEN JR® (epinephrine injection, USP) Auto-Injector (or the authorized generics)

The drug in EPIPEN and EPIPEN JR Auto-Injectors (and their authorized generics) is epinephrine. It’s important to administer epinephrine at the first signs of anaphylaxis.

According to National Food Allergy Guidelines, epinephrine is the first-line treatment for life-threatening allergic reactions. A delay in administering epinephrine can be life-threatening.

If you, your child or someone you're caring for shows signs or symptoms of a life-threatening allergic reaction, administer EPIPEN or EPIPEN JR Auto-Injector immediately as prescribed and seek emergency medical care.

If you inject a young child, hold their leg firmly in place before and during the 3 second injection to prevent injuries.
