Definition: Anaphylactic shock is a severe and potentially life-threatening allergic reaction that can occur suddenly after exposure to an allergen. Symptoms can include hives, swelling of the throat, difficulty breathing, a rapid, weak pulse, and loss of consciousness. Immediate medical attention and treatment with epinephrine are essential to counteract this reaction.

What is Anaphylactic Shock?

Overview:

Anaphylactic shock is a medical emergency that results from a severe allergic reaction. Common triggers include certain foods, medications, insect venom, and latex. The body’s immune system overreacts to the allergen, leading to a rapid and dramatic drop in blood pressure and difficulty breathing.

Key Facts about Anaphylactic Shock:

Speed is crucial in treating anaphylactic shock. Immediate administration of epinephrine can reverse the symptoms and prevent a fatality.

People with known severe allergies often carry an auto-injector of epinephrine (EpiPen) for immediate self-administration in case of exposure.

Even if symptoms improve after an injection of epinephrine, it’s still important to go to the emergency department for further evaluation and treatment.
