Allergen specific immunotherapy

Abstract

Allergen immunotherapy is a disease modifying therapy and prevents the progression of allergic diseases especially in those patients who demonstrate specific IgE antibodies to relevant allergens. Immunotherapy involves giving gradually increasing doses of the allergen, to which the person is allergic. This in turn causes the immune system to become less sensitive to the substance, which reduces the symptoms of allergy when the same allergen is encountered in future. This article elaborates the various components involved in immunotherapy.
