urticaria
"Chronic hives for 1 year - took all the antihistimines and prednisone.  The only thing that kicked the hives was prednosolone pack that I recently took after the Xolair shot did not work.  I have had 8 Xolair shots (monthly injections) and at first they were very effective.  After the 6th one, I had recurring hives and angiodema return so I am back on large dose of allertec and nightly taking hydroxyzine.   Xolair seems to help with the size of hives and the amount when breaking out.  Weight gain is definitely noticed but due to prednisone prior to the shot, I can't be certain it is all due to Xolair.  Will continue on Xolair and perhaps look at Kenalog shot."
