Desensitization shots are generally useful for patients with allergic rhinitis who have identified a single or few allergens.
Desensitization shots are specific desensitization therapy, also known as desensitization therapy, which is a treatment for allergic diseases (e.g., allergic asthma, allergic rhinitis, etc.) to allergenic substances. The aim is to alleviate symptoms, shorten the duration of attacks and reduce the amount of medication used. It is an immunotherapy that specifically targets diseases with specific allergen-induced allergic reactions mediated by immunoglobulin E. The treatment is based on the identification of the allergen and the identification of the cause of the allergic reaction.
The method first needs to identify the allergen, make the allergen into different concentrations of the preparation, and give it repeatedly to the corresponding patients, gradually inducing the patients to tolerate the allergen without allergic reactions. It is mainly used for patients with allergic rhinitis caused by a single or a few allergens or those who cannot avoid contact with allergens. It is the only method that can change the natural course of allergic rhinitis.
However, the treatment period of this method is long, and adverse reactions such as systemic allergic reaction or even anaphylaxis may occur if not used properly. It is contraindicated for patients with severe cardiovascular diseases, immune system diseases, cancer and patients who cannot identify allergens.
