Background
Allergy injections are a treatment plan the patient and the doctor work together to agree upon that will assist in allergy relief. The injections are treatments called immunotherapy that help build up immunity to your specific allergies. Treatment can run five to six years, and can initially take anywhere from six months to a year to take effect. Allergen immunotherapy is the repeated administration of allergen vaccines to allergic individuals in order to provide long-term relief of symptoms and improving the quality of life during subsequent natural allergen exposure.
Immunotherapy is effective in allergic rhinoconjunctivitis and allergic asthma, and in patients who develop systemic anaphylactic reactions to fire ants. All patients should be observed in the clinic for at least 15 minutes following injections. In view of the remote risk of serious systemic side effects, the risk/benefit ratio should be carefully considered in all cases.
Long-Term Benefits
Allergen immunotherapy has been proven, in several studies, to confirm long-term benefits following discontinuation. For example, immunotherapy can reduce the onset of new allergen sensitivities in children. In a prospective randomized, controlled trial of pollen immunotherapy in children with seasonal allergic rhinitis, development of asthma was followed over a period of five years. Two years following cessation of immunotherapy, there was a marked reduction in the risk of development of physician-diagnosed asthma (odds ratio 2.7 95% confidence intervals 1.3-5.6), compared to controls (10). Taken together, these studies emphasize the important prophylactic value of injection immunotherapy, which is in contrast to pharmacotherapy, where relapse of symptoms occurs immediately following.
