What Are Allergic Reactions?

 

An allergic reaction may occur anywhere in the body, in the skin, eyes, lining of the stomach, nose, sinuses, throat, and lungs - places where immune system cells are located to fight off invaders that are inhaled, swallowed, or come in contact with the skin. Reactions may result in:

  • Rhinitis - nasal stuffiness, sneezing, nasal itching, nasal discharge, itching in ears or roof of mouth
  • Allergic conjunctivitis - red, itchy, watery eyes
  • Atopic dermatitis - red, itchy, dry skin
  • Urticaria - hives or itchy welts
  • Contact dermatitis - itchy rash
  • Asthma (airway problems such as shortness of breath, coughing, wheezing)
