I've been on Xolair for over a year and am still receiving allergy shots (immunotherapy). No problems with asthma, but I do occasionally get short of breath when there is a lot of pollen/mold in the air.
I have gained a lot of weight and am not happy about it. But the same thing happened when I was taking prednisone. I've also had some problems with depression and wonder if it is related to the Xolair.
