anaphylactic shock

Meaning

A severe, potentially life-threatening allergic reaction that causes the body's immune system to release a flood of chemicals, leading to a sudden drop in blood pressure and narrowing of airways.

Examples

• The emergency medical team administered an epinephrine injection immediately to reverse the patient's anaphylactic shock.
• People with severe allergies are often advised to carry an auto-injector to prevent death from anaphylactic shock.
