Anaphylaxis

Anaphylaxis is a severe allergic reaction that can lead to death if not given immediate medical attention.

Anaphylactic reactions most commonly occur when someone is exposed to something they’re allergic to, such as insect stings, latex, medications and/or foods.

If someone is exposed to a substance they’re allergic to, their immune system will overreact and release chemicals that bring about symptoms of an allergic reaction.

A person who has been diagnosed as being at risk of anaphylaxis, must always have on hand, an auto-injectable device containing epinephrine such as an EpiPen. A single dose of this medication should be immediately injected into the thigh of the affected person in the event of an anaphylactic reaction, followed by calling 911.

Typical warning signs involve several parts of the body
