HOW DOES ALLERGEN IMMUNOTHERAPY WORK?
Allergen immunotherapy is a medical therapy for preventing or alleviating allergic reactions to a particular allergen. In this type of therapy, the allergen causing an allergic reaction is given to the person to reduce the allergic reaction.
The allergen is injected in a gradually increasing dose, which triggers the immune system to develop immunity or tolerance to the allergen.
There are two phases of the immune response:
Build-up phase: In this phase, the allergen is injected in increasing amounts, about once to twice per week. The length of this phase may range from three to six months.
Maintenance phase: The maintenance phase is started once an effective dose is reached. Depending on the person’s response to therapy, the maintenance dose is usually injected once every two or three weeks for three to five years.
