Desensitization for allergies (immunotherapy)
Alice,
A friend of mine is interested in desensitization therapy for cat allergy. He has consulted two allergists: one claimed a nearly 100 percent success rate; the other suggested the procedure was virtually worthless, and possibly dangerous. I suspect the truth lies somewhere between these two extremes. Is there any reliable information concerning the success rate for this procedure, what kinds of problems might be encountered, and how long one might expect it to take?
