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.

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
• low blood pressure, dizziness, fainting, rapid or weak heartbeat, anxiety, or feeling of "impending doom"
• flushing, itching, hives, or feeling warm
• swelling of the throat or tongue, throat tightness, hoarse voice, or trouble swallowing

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. Your healthcare provider should talk to you about getting medical treatment if you have symptoms of an allergic reaction after leaving the healthcare provider’s office or treatment center.

Whether you're diagnosed and uncontrolled on inhaled corticosteroids and ready to discuss treatment options or not yet diagnosed and want to know if your asthma is allergic asthma, these discussion guides can help start the conversation between you and your doctor.
