What are the symptoms of anaphylaxis?

Anaphylaxis usually begins with severe itchiness in the eyes or face. Within a few minutes, you may start experiencing more severe symptoms, including:

  • Swelling, which may cause swallowing and breathing difficulties.
  • Shortness of breath.
  • Hives.
  • Difficulty swallowing.
  • Red rash.
  • Abdominal (belly) pain.
  • Chest tightness.
  • Cramps.
  • Diarrhea.
  • Feeling of doom or dread.
  • Vomiting.
  • Wheezing.

If you notice symptoms, get medical help right away or use your allergy medication. Without treatment, more severe, life-threatening anaphylaxis symptoms may occur:

  • Drop in blood pressure, with a weak pulse or confusion.
  • Increased heart rate.
  • Shock.
  • Sudden weakness.
  • Unconsciousness.
