Omalizumab - What is it for

Omalizumab is a synthetic protein that is similar to natural proteins produced by the body. It is used for the treatment of allergic asthma and chronic spontaneous urticaria (CSU) in adults and adolescents (12 years of age and older). Omalizumab works by blocking a substance called immunoglobulin E (IgE), which is produced by the body. IgE plays a key role in causing allergic asthma or CSU.

Allergic asthma

It is used to prevent asthma from getting worse by controlling symptoms of severe allergic asthma in those who are already receiving asthma medicine, but whose asthma symptoms are not well controlled by medicines such as high-dose steroid inhalers or beta-agonist inhalers.

Do note that Omalizumab does not treat acute asthma symptoms, such as a sudden asthma attack. Therefore, Omalizumab should not be used to treat such symptoms.

Chronic spontaneous urticaria (CSU)

It is used to treat CSU in those who are already receiving antihistamines, but whose symptoms are not well-controlled by these medicines.

Do note that Omalizumab is not meant to prevent or treat other allergy-type conditions, such as food allergy or hay fever.
