This medication can rarely cause a very serious (sometimes fatal) allergic reaction. This reaction has occurred after the first dose or after later doses, even more than one year after starting treatment. The risk is greater if you have a history of severe allergies to other medications or to foods. Your health care professional will monitor you closely during treatment for any signs of an allergic reaction. Get medical help right away if you notice any symptoms of a serious allergic reaction, including: itching/swelling (especially of the face/tongue/throat), flushing, trouble breathing, severe dizziness, fainting, or rash/hives.
If you have had an allergic reaction to omalizumab, you must never use omalizumab again.
