Anaphylaxis: Overview and More

Anaphylaxis is a serious and life-threatening allergic reaction. The most common allergens that cause anaphylaxis are food, insect bites, medications, and latex.

Symptoms of anaphylaxis come on suddenly and can include hives, vomiting, swelling of the tongue, face, or throat, trouble breathing, and fast or slow heartbeats. If the reaction progresses to anaphylactic shock , it can be fatal.

Anaphylaxis is a medical emergency and is treated with adrenaline (adrenaline). After an anaphylactic episode, it is important to carry an epinephrine autoinjector ( EpiPen ) with you at all times in case you come in contact with a particular allergen again.
