What Is a Life-Threatening Allergic Reaction (Anaphylaxis)?
Anaphylaxis (a-na-fi-LAX-is) is a life-threatening allergic reaction that can occur quickly (as fast as within a couple of minutes). Symptoms of anaphylaxis vary, but can include hives, itching, flushing, and swelling of the lips, tongue, and roof of the mouth. The airway is often affected, resulting in tightness of the throat, chest tightness and difficulty breathing. These reactions can also be accompanied by chest pain, low blood pressure, dizziness and headaches. Anaphylaxis can be caused by a number of triggers, including but not limited to certain foods, stinging and biting insects, medications and latex.
Make sure you speak with your health care professional about how to identify the signs and symptoms of anaphylaxis. If you, your child or someone you're caring for shows signs or symptoms of anaphylaxis, inject the health care professional-prescribed EpiPen® (epinephrine) or EpiPen Jr® (epinephrine) immediately and seek emergency medical attention. Failure to inject the EpiPen Auto-Injector at the first signs of anaphylaxis can be life-threatening.
