Omalizumab is a monoclonal antibody used to manage severe asthma and chronic hives.
It is commonly used for:

- Nasal polyps: Manages nasal polyps not adequately controlled by nasal corticosteroids alone, as prescribed by your doctor.

How Omalizumab works
- Omalizumab is a monoclonal antibody that targets a substance called immunoglobulin E (IgE), which plays a key role in allergic reactions.
- By binding to IgE, Omalizumab prevents it from attaching to mast cells, the cells responsible for releasing chemicals that trigger allergy symptoms.
- This reduces the release of these chemicals, which helps ease airway inflammation in asthma and reduce the severity of hives.
