What Is Immunotherapy and Can It Help With My Allergies?

Allergy symptoms can make life miserable. When medication and trigger avoidance aren’t enough, is there anything else you can try? Immunotherapy — which alters your immune system’s inflammatory response — could be the solution you’ve been seeking.

Options for Allergy Testing and Treatment

Are your allergies putting a damper on your favorite activities? Have you noticed a reaction to something to which you didn’t think you were allergic? In either case, allergy testing could put you on the fast track to treatment.
