How Does Xolair® (Omalizumab) Work?
When people with allergic asthma encounter a substance they are sensitive to, such as house dust mites or animal fur, this sets off a mechanism in which the body over-produces an ‘antibody’ molecule called immunoglobulin E or IgE. An excess of IgE can lead to serious harm by triggering the symptoms of allergic asthma – shortness of breath, wheezing and coughing. By reducing the availability of IgE, Xolair (omalizumab) targets a root cause of allergic asthma attacks.
