What Anaphylaxis?

Anaphylaxis is a severe, life-threatening allergic reaction that can occur within minutes of exposure to an allergen. It is characterized by a sudden drop in blood pressure, difficulty breathing, hives, swelling of the face, tongue, and throat, and a rapid pulse. Anaphylaxis can be caused by a variety of allergens, including peanuts, tree nuts, shellfish, milk, eggs, wheat, soy, insect stings, and bee stings. Treatment for anaphylaxis typically involves the use of epinephrine (adrenaline) and other medications to reverse the symptoms of the reaction.
