Anaphylaxis is a severe and potentially life-threatening allergic reaction that can occur rapidly after exposure to an allergen. Common triggers include certain foods, insect stings, medications, and latex. Symptoms may include difficulty breathing, swelling of the throat, hives, and a rapid drop in blood pressure. Immediate medical attention is crucial, as anaphylaxis can escalate quickly. Treatment for anaphylaxis typically involves the administration of epinephrine, which can help reverse the symptoms. Individuals at risk are often advised to carry an epinephrine auto-injector and to avoid known allergens. Prompt recognition and response are essential for a positive outcome.
