urticaria
"I am 72 years old and have suffered with Chronic Urticaria for 18 months now 24/7 and my antihistamines and prednisone are no longer helping. My Dr. suggested that I try Xolair. I have had my 2nd injections today and have had no decrease in my hives. I have read that it may take 2 or 3 months before it kicks in but I was sure hoping that I would have some relief in the first month, especially because of the cost of this drug. I will continue for a couple more months to give it a fair chance."
