OMALIZUMAB prevents the symptoms of asthma. It is often prescribed when other medications have not worked well enough or cannot be tolerated. It may also be used to treat nasal polyps, chronic hives, and food allergies. It works by reducing the release of substances in your body that cause allergy symptoms. This decreases inflammation of the airways and makes it easier to breathe. It also reduces itching. It can also reduce the body’s response to some food allergens after accidental exposure. Do not use it to treat a sudden asthma attack. Do not use it to treat emergency allergic reactions. Continue to avoid foods you are allergic to. It is a monoclonal antibody.
