asthma, maintenance
"I have been taking xolair for 5 years now. It is an amazing medicine. I only have one fully developed lung so I had asthma pretty bad. I am also allergic to elm trees so I would get hives and itching alot when I was outside. No more trips to er anymore and I can go outside and not have to wear jackets in summer due to the trees giving me hives. I have had no side effects so far. All I know is this drug works for me. It has changed my life."
