What is the role of allergen immunotherapy in asthma management?

The role of allergen immunotherapy in asthma management is to reduce sensitivity to specific allergens. This treatment involves the gradual exposure of the patient to the allergens they are sensitive to, often through injections or sublingual tablets. Over time, this exposure can help the immune system build a tolerance to those allergens, thereby decreasing the allergic response when a person encounters them in the environment.

By reducing sensitivity, immunotherapy can lead to a decrease in the frequency and severity of asthma symptoms triggered by allergens. It is important to note that while immunotherapy can significantly improve asthma control for those with allergic triggers, it does not remove allergens from the environment, cure asthma, or completely eliminate symptoms. Asthma management is a multifaceted approach that may include medications, lifestyle changes, and avoiding known triggers, in addition to immunotherapy for those whose symptoms are linked to specific allergens.
