I have tried all types of treatment but there is no relief from my allergic rhinitis symptoms. My doctor has now advised immunotherapy. What is this? How will it help?

Immunotherapy is an option for people who have tried other treatments but still have allergy symptoms. Injections or sublingual tablets containing a very small amount of the allergen that one is allergic to are given on a regular schedule so that one's body gets used to the allergens. This helps decrease the body’s sensitivity to the allergens. Over time, the allergy symptoms become less severe.
