Anti-allergy treatment is divided into two main modalities: non-specific treatment and specific treatment, also known as immunotherapy. Non-specific treatment is the commonly used drug therapy, including three kinds can be applied individually, but also often in combination. The first category is antihistamines, also known as anti-allergic drugs, including the first generation of chlorpheniramine, etc., and the second generation of loratadine, etc., which are routinely applied in combination, taking the second generation of anti-allergic drugs in the morning and the first generation of anti-allergic drugs in the evening. The second category is drugs to improve vascular permeability, which can be vitamin C, intravenous calcium, triclopidine, etc. The third category is glucocorticoids, which can inhibit the antigen-antibody response and reduce the exudation of inflammation. Examples are prednisone, hydrocortisone, dexamethasone, etc. Specific treatment is immunotherapy, which means that the allergic patient is repeatedly exposed to gradually increasing amounts of allergen extracts to improve the patient’s tolerance to the allergic substance and to reduce or control the symptoms of allergy. It is mainly used for allergic diseases with few allergens and significant time episodes, such as allergic rhinitis and bronchial asthma.
