Omalizumab (By injection)
Antiasthma, Immunological Agent (About this – PubMed Health)
Uses of This Medicine
Omalizumab injection is used to treat moderate to severe persistent allergic asthma. It is used when a patient’s asthma has not been controlled sufficiently on other asthma medicines. This medicine will not relieve an asthma attack that has already started.
Omalizumab injection is also used to treat chronic idiopathic urticaria (CIU) in patients who continue to have hives that are not controlled by an antihistamine.
Omalizumab is a medicine called an IgE blocker. IgE is short for immunoglobulin E. IgE is a substance that occurs naturally in the body in small amounts. This substance plays an important role in allergic asthma. When people with allergic asthma breathe in a year-round allergen, such as cat or dog dander, their bodies make more IgE. This may cause a series of reactions in your body that can lead to asthma attacks and symptoms. Omalizumab works by helping to block IgE.
This medicine is to be given only by or under the direct supervision of your doctor.
