I took the shots for a little over 5 years. At first it was 4 shots twice a week. When I got to maintenance, I gave them to myself--4 shots only once a week. I was allergic to about 90% of the things they tested me for. The shots have helped me immeasurably. I know they don't work for everybody. I'd taken an antihistamine every day of my life for over 20 years before starting on immunotherapy. I "graduated" last fall. Since that time I think I've had 3 Allegras. I'll never be totally allergy free--I can't even imagine what that's like. But if the shots help you and you can stick it out, it's well worth it. --Hah, I said stick!!!
