An allergy is a specific reaction of the body’s immune system to a normally harmless substance, one that does not bother most people. People who have allergies often are sensitive to more than one substance. Types of allergens that cause allergic reactions include:

  • Pollens
  • House dust mites
  • Mold spores
  • Food
  • Latex rubber
  • Insect venom
  • Medicines
