Xolair

Does anybody know what this is or have experience with it? I just got off the phone with my asthma doctor and they told me to come in and pick up papers for Allergy tests and IGE tests. They are trying to qualify me for Xolair injections. If I get them I will have to repeat the injections every 2 to 4 weeks. She said they have a lot of bad side affects and in fact when you get the injection you have to stay at the doctor office for at least an hour and they give you an epi pen when you get the injection.

Any information you may have or experience, please let me know.
