Desensitization therapy is the only treatment for allergic rhinitis and/or asthma that addresses the root cause of the disease. Its main mechanism is to desensitize the main allergens that trigger rhinitis or asthma symptoms, so that the body can develop tolerance and achieve the goal of long-term treatment. Its main advantages are: 1, long-term alleviation of allergic symptoms; 2, prevention of asthma; 3, prevention of new allergies; 4, no toxic side effects on the body, no impact on growth and development. In order to maximize the efficacy and safety of the treatment, our center mainly uses the Danish Antarctica desensitization vaccine. This vaccine has high activity and stability and is the most standardized allergen immunotherapy vaccine in the world. Main treatment modalities and costs: 1. Classical treatment modalities The total course of treatment is 2 to 3 years. The first 3 months or so is a weekly treatment (subcutaneous injection, observation for 30 minutes), gradually changed to once every 2 weeks, once a month, once a month and a half. The overall cost is about 12,000 RMB. 2.Cluster treatment Shorten the course of conventional treatment in the early stage, its safety and efficacy are similar to the classic treatment, and can greatly save the time of treatment in the early stage. The injection treatment method is similar to the former, and the cost of pre-treatment is slightly higher than the classic treatment.
