About allergen immunotherapy
Allergen immunotherapy (AIT) is an allergy treatment designed to treat the underlying cause of the disease as well as have a carry-over effect on all symptoms. After an accurate diagnosis of the type of allergy and responsible allergens, patients, in line with their healthcare practitioner’s prescription, receive a targeted treatment. Through the repeated administration of specific allergens, the immune system builds resistance1 thus reducing symptoms when patients are exposed to the allergen in their environment.
