asthma, maintenance
"I have been xolair for two months.  Wow, what a difference this has made.  I would cough all day and used my inhalers more than directed.  Now I don't cough much and don't wheeze.  I use inhalers once a day now.  Two weeks after the first shot I could tell a difference.  This is a great drug.  I do feel some tiredness with it but it is tolerable."
