What is allergy immunotherapy?

Allergy immunotherapy is a form of long-term treatment that decreases symptoms for many people with allergic rhinitis, allergic asthma, conjunctivitis (eye allergy) or stinging insect allergy.

Allergy immunotherapy treats the cause of your allergies, not just the symptoms. It builds tolerance by exposing your immune system to small amounts of what you’re allergic to on a regular basis. This can be done with weekly injections of “allergy shots,” the daily self-administration of “allergy drops” or “allergy toothpaste”, or by taking dry “allergy tablets”.

Over time, immunotherapy changes your immune system so that it is more “tolerant” of the allergens. As allergen tolerance grows, your allergies and their symptoms decrease, sometimes to the point that an allergy sufferer does not notice them anymore. Immunotherapy may also prevent conditions that often go along with allergies, like chronic sinusitis or asthma.
