The allergy shots improve the patient's natural resistence to the allergens and minimize or eliminate the need for medications.
Most patients begin to experience reduced symptoms soon after the treatment is begun.
Allergy shots usually must be continued for several years, but sometimes can be discontinued with immunity maintained for a lifetime. Allergy shots have been available since the early part of the century. The treatment has been continuously improved and refined. Performed by a trained and experienced physician, allergy shots are very safe. However, because the treatment involves introducing a substance to which the person is allergic, in rare cases systemic reactions can occur.
