I was on Xolair and it was so expensive. I see the generic name is omalizumab and wondered if it is less expensive. I did really well when I was on Xolair and hardly had to take anything else and never really had to go to the clinic for my asthma my Drs want me to go back on it. When I was on the Xolair there was no generic availible. Is the generic available now and is it less expensive
