Treatment of allergy is a cooperative venture with both patient and physician as participants. The goal of treatment is to produce an allergic balance so that the patient may be freed of existing allergic illness and avoid the development of new allergy problems. A basic part of management is teaching the patient to eliminate the offending allergens whenever possible. Since certain allergens cannot be eliminated, the reaction of the patient to these substances is controlled by desensitization. Desensitization is the technique of injecting small but increasing amounts of the allergen to control the allergic reaction so that the patient has little or no reaction when exposed to the offending substance. In our office, desensitization by injection is used for inhalant allergens. Food sensitivities can be dealt with by diet control. In conjunction with desensitization, patients will be taught to avoid and eliminate allergens.
