Allergic Conditions: Allergen

An allergen is the source of an allergy-producing substance, the allergy-producing substance itself, or one or more of the specific proteins that makeup the substance and provoke the immune response, including IgE antibodies. Allergens are often common, usually harmless substances such as pollen, mold spores, animal dander, dust, foods, insect venoms and drugs.

Resources about allergens:

Please visit an allergist for more information on allergic disease and your individual medical condition. If you need to locate an allergist in your area, visit the Academy’s online Physician Referral Directory.
