What is Xolair?
Xolair is a type of medication that is injected under the skin. The active substance omalizumab ensures that the production of specific antibodies in the body is suppressed. This will prevent allergic reactions of the respiratory distress and this will reduce attacks.

Usually you use Xolair in combination with other medications for asthma, such as an inhaled corticosteroid.
How to use Xolair?
Xolair is administered by means of an injection. This drug works very long: injections are usually needed once every 2 to 4 weeks. It takes several weeks to months before the effect of Xolair is noticeable: the frequency and severity of shortness of breath attacks gradually decrease.
