About XOLAIR

XOLAIR is an injectable prescription medicine, given under the skin by a nurse or doctor every 2 or 4 weeks, that treats moderate to severe persistent allergic asthma in patients 6 years of age or older whose asthma symptoms are not controlled by asthma medicines called inhaled corticosteroids. A skin or blood test is performed to see if you or your child have allergies to year-round allergens. XOLAIR is not used to treat other allergic conditions, acute bronchospasm or status asthmaticus.

What Is the Most Important Information I Should Know About XOLAIR?

XOLAIR may cause serious side effects, including: Severe allergic reaction. A severe allergic reaction called anaphylaxis can happen when you receive XOLAIR. The reaction can occur after the first dose, or after many doses. It may also occur right after a XOLAIR injection or days later. Anaphylaxis is a life-threatening condition and can lead to death. Go to the nearest emergency room right away if you have any of these symptoms of an allergic reaction:

  • wheezing, shortness of breath, cough, chest tightness, or trouble breathing

Your healthcare provider will monitor you closely for symptoms of an allergic reaction while you are receiving XOLAIR and for a period of time after your injection.
