This is the best medication I have ever run into besides my lovely albuterol inhalers. Xolair is for individuals who suffer from not only asthma but from allergic types of asthma also. It is only in injectable form and must be taken in the doctor's office. For those of us with huge IGE counts, this medication has been a godsend. The only downfall is trying to get funding to help with co-pays and the like. This is no cheapie allergy shot thing. Since I have been taking Xolair I rarely have allergic reactions bad enough to send me to the ER and have only had one hospital stay in the past two years. A miracle. I have a severe latex allergy and I often run into this product no matter how careful I am. Xolair has practically changed and saved my life.
