There have been revisions to the prescribing information for Xolair. The drug is used to treat moderate to severe asthma in individuals 12 years old and older. There is a risk of anaphylaxis with use of Xolair. Anaphylaxis is a severe allergic reaction, with symmptoms such as wheezing, trouble breathing, hives, dizziness and throat tightness. New information about this risk has been added to the Xolair prescribing information, which now includes a new Boxed Warning, updated Warnings, Precautions and Adverse Reactions- – Postmarketing Spontaneous Reports. Also, each dosage of Xolair is to be accompanied by a New Medication Guide regarding the anaphylaxix risk.
