Anaphylaxis is a severe and potentially life-threatening allergic reaction. It can occur quickly, within minutes or hours of exposure to an allergen, such as peanuts, bee venom, or certain medications.

Symptoms of anaphylaxis can include skin reactions, such as hives or itching, swelling of the face, lips, or tongue, difficulty breathing, wheezing, chest tightness, low blood pressure, rapid or weak pulse, nausea, and confusion.

Anaphylaxis can be treated with an emergency injection of epinephrine, followed by a visit to the hospital for further medical attention. People who are at risk of anaphylaxis should carry an epinephrine auto-injector and know how to use it. In some cases, ongoing medical management and lifestyle changes may be necessary to prevent future reactions.

It is important for individuals to work closely with their healthcare provider to create an action plan in case of a future anaphylactic reaction.
