Some symptoms of an allergic reaction to peanuts include itching in the throat and mouth; hives, skin redness or swelling; a stuffy or runny nose; stomach problems such as nausea, diarrhea or cramps; and in some cases, chest tightness and difficulty breathing. These symptoms usually start within just a few minutes of contact with peanuts. Some people with peanut allergies experience a more severe reaction called anaphylaxis, which is an emergency that requires immediate medical attention. Symptoms of anaphylaxis include dizziness, fainting, fast pulse, shock and difficulty breathing. Anaphylaxis is more common in people with peanut allergies than with any other allergy. If you know you have a severe peanut allergy, you should always carry an epinephrine injector, and a medical alert bracelet.
