How does immunotherapy work to treat allergies?

ANSWER

Immunotherapy may be one of the most effective forms of treatment if you suffer from allergies more than three months of the year. Allergy shots expose you to gradually increasing levels of the offending allergen to help your immune system build tolerance. The FDA has approved several under-the-tongue immunotherapy tablets that can be taken at home. The prescription tablets, called Grastek, Ragwitek, and Oralair, are used for treating hay fever and work the same way as shots -- the goal is to boost a patient’s tolerance of allergy triggers. Odactra is an under the tongue medication which can relieve symptoms of allergies to dust mites.
