Using Xolair for Chronic Idiopathic Urticaria

Xolair is also approved for chronic idiopathic uricaria (which means chronic hives of unknown cause). Hives are red, raised welts on the skin. They are usually very itchy. Hives are commonly caused by allergies, although other factors (such as stress) can also cause them.

Many people get hives chronically without finding any cause. Xolair is approved to treat chronic hives of unknown cause in people age 12 and over who still have symptoms despite treatment with antihistamine medications.

How Does Xolair Work?

Xolair is an asthma medication that belongs to a group of drugs called monoclonal antibodies. Monoclonal antibodies are used to treat a wide variety of conditions, including asthma. Xolair works by binding to IgE antibodies. IgE antibodies play an important role in allergic reactions, and by binding to IgE antibodies, Xolair blocks their effects. By preventing allergic reactions, Xolair can help to prevent asthma attacks.

It is currently unknown how exactly Xolair works to treat chronic idiopathic urticaria. 

Xolair Use in Children

Xolair is approved for the treatment of asthma and chronic idiopathic urticaria in children 12 years of age and older. Be sure to talk with your healthcare provider about the possible risks and benefits of this medication in children.
