urticaria
"I have had daily hives from June 2015 until October 2015, Despite prednisone and mega dose of Anti-Histamine, my hives kept coming every single day. I started xolair in October 2015 and took my first 150 ml shot in October 30, 2015, then In November27, 2015 and then in December 23, 2015. Unfortunately after my 3rd shot and on Christmas day, my hives came back with vengeance and I kept having them daily. The in January 13, 2016, I took 2 shots (300 ml) and still nothing. My hives have been getting worse on a daily basis. I am due for 2 shots next week again. I hope it will work out. Did anyone experience that? Xolair works for couple months then stopped working? Do you think it will work again after few more shots?"
