I have been on Xolair for three years now. Previous to this treatment I was on 1500mg of Serevent a day and my Ventolin was with me at all times. I was in and out of hospital for 2 week stays (ICU was the norm) at least 5 times a year. I was on countless doses of steroids and antibiotics and in 1990 my heart stopped.Since I've been on Xolair my asthma has been fantastic. I go to hospital twice a month for two injections - one in each arm (had to get over my terror or injections, but they work so well it doesn't bother me anymore!), and after I'd had about 4 months’ worth I can now go out without my Ventolin, I rarely take my preventative inhaler and I've only been admitted to hospital once. This was late 2008 when everyone was hit badly by the flu.I have two cats (I was bought up with cats and cannot live without them!), they affect me when I first get them but after a couple of months I get used to them.If your asthma is bad enough I cannot recommend this drug enough.
