There are two types of allergy treatments: Medication and Immunotherapy (allergy shots)
Immunotherapy or known as allergy shots is a preventive treatment for allergic reactions to substances such as grass, trees and weeds pollens, house dust mites, pet dander, mold spores and bee venom. Immunotherapy involves giving gradually increasing doses of the substance, or allergen, to which the person is allergic. The incremental increases of the allergen cause the immune system to become less sensitive to the substance, probably by causing production of a “blocking” antibody, which reduces the symptoms of allergy when the substance is encountered in the future. Immunotherapy also reduces the inflammation that characterizes rhinitis and asthma.
Before starting treatment, the allergist and patient identify trigger factors for allergy symptoms. Skin or sometimes blood tests are performed to confirm the specific allergens to which the person has antibodies.
