What Is Anaphylaxis?

Anaphylaxis is a severe, potentially life-threatening allergic reaction that can occur within seconds or minutes of exposure to an allergen. It is characterized by a sudden drop in blood pressure, difficulty breathing, and a rash. Anaphylaxis can be triggered by a variety of allergens, including foods, insect stings, and medications.

Symptoms of anaphylaxis can include:

- Difficulty breathing

- Wheezing

- Chest pain

- Rapid pulse

- Low blood pressure

- Dizziness

- Nausea

- Vomiting

- Diarrhea

- Abdominal pain

- Hives

- Swelling of the face, lips, tongue, or throat

- Loss of consciousness

Anaphylaxis is a medical emergency and requires immediate treatment. If you think you are experiencing anaphylaxis, call 911 immediately.

Treatment for anaphylaxis includes:

- Epinephrine (adrenaline) injection

- Oxygen

- Intravenous fluids

- Antihistamines

- Corticosteroids

If you have a known allergy that could cause anaphylaxis, it is important to carry an epinephrine auto-injector (EpiPen) with you at all times. You should also wear a medical ID bracelet or necklace that states your allergy.

Preventing anaphylaxis is the best way to manage it. If you have a known allergy, avoid exposure to the allergen. You should also talk to your doctor about an allergy action plan.
