XOLAIR, Xolair PFS, Xolair

What is this medication? Xolair is a prescription injectable medication used to treat several different conditions triggered by the immune system. It is primarily prescribed for adults and children six years of age and older who have moderate to severe persistent asthma that is not well controlled by inhaled corticosteroids. This medication is specifically for patients whose asthma is triggered by year-round allergens in the air. Additionally, it is used to treat chronic spontaneous urticaria, which involves chronic hives that do not have a known cause and have not responded to antihistamine treatments.

This medication is also approved for the treatment of chronic rhinosinusitis with nasal polyps in adults when used alongside other treatments like nasal corticosteroids. More recently, Xolair has been indicated for use in children and adults to help reduce the risk of severe allergic reactions, including anaphylaxis, that may occur after accidental exposure to one or more foods. It works by blocking immunoglobulin E, a protein in the body that plays a key role in allergic responses. It is important to note that this medicine is not intended for the emergency treatment of an allergic reaction or asthma attack.
