MedlinePlus overview of Anaphylaxis

Anaphylaxis is a serious allergic reaction. It can begin very quickly, and symptoms may be life-threatening. The most common causes are reactions to foods (especially peanuts), medications, and stinging insects. Other causes include exercise and exposure to latex. Sometimes no cause can be found.

It can affect many organs:

Skin - itching, hives, redness, swelling

Nose - sneezing, stuffy nose, runny nose

Mouth - itching, swelling of the lips or tongue

Throat - itching, tightness, trouble swallowing, swelling of the back of the throat

Chest - shortness of breath, coughing, wheezing, chest pain or tightness

Heart - weak pulse, passing out, shock

Gastrointestinal tract - vomiting, diarrhea, cramps

Nervous system - dizziness or fainting

If someone is having a serious allergic reaction, call 911. If an auto-injector is available, give the person the injection right away.
