By Mayo Clinic staffAn allergic response to peanuts usually occurs within minutes after exposure, and symptoms range from mild to severe. Peanut allergy symptoms can include:
- Skin reactions such as hives, redness or swelling
- Itching or tingling in or around the mouth and throat
- Digestive problems such as diarrhea, stomach cramps, nausea or vomiting
- Tightening of the chest

Anaphylaxis
Peanut allergy is one of the most common causes of anaphylaxis, a medical emergency that requires treatment with an epinephrine (adrenaline) injector (EpiPen, EpiPen Jr or Twinject) and a trip to the emergency room.
Anaphylaxis signs and symptoms can include:
- Constriction of airways
- Swelling of your throat that makes it difficult to breathe
- A severe drop in blood pressure (shock)
- Rapid pulse
- Dizziness, lightheadedness or loss of consciousness
When to see a doctor
Talk to your doctor if you think you could be allergic to peanuts, especially if you had a severe reaction.
Seek emergency treatment if you have a severe reaction to peanuts, especially if you have any signs or symptoms of anaphylaxis. Call 911 or your local emergency number for severe dizziness, severe trouble breathing or loss of consciousness.
