HOW DOES SUBLINGUAL IMMUNOTHERAPY WORK?

The immune system of the gastrointestinal tract tends to “tolerate” foreign substances, meaning that it does not respond in an over-active way to swallowed material.

When sublingual immunotherapy is administered into the gastrointestinal tract, the immune system tolerates the allergen, instead of causing an over-reactivity of the immune system, such as with allergic disease.  This results in less allergy symptoms when the body is exposed to the allergy source, such as airborne pollen or pet dander.
