What Is Omalizumab Used For?
Omalizumab is used for treating allergic asthma in adults and children as young as 12 years old. The drug works by blocking the action of a certain antibody that can cause allergic reactions and asthma attacks. Occasionally, omalizumab is prescribed for something other than allergic asthma. Among these potential “off-label” omalizumab uses are the prevention of severe food allergies or other types of allergies (such as seasonal allergies).
