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, perhaps by causing production of a particular "blocking" antibody, which reduces the symptoms of allergy when the substance is encountered in the future." rel="tooltip">免疫疗法对花粉严重过敏的人有以下选择:

相反的情况也可能是正确的:花粉数量可能很低,但你可能会发现自己周围的花粉之一引发了你的过敏。
通过测试,过敏症专科医生可以确定是哪些花粉引起了你的症状。过敏症专科医生还可以通过确定哪些药物对你的过敏源最有效来帮助你缓解症状。
