A patient's healthcare provider should watch the patient for some time in the office for signs or symptoms of anaphylaxis after injecting Xolair. If patients have signs or symptoms of anaphylaxis, they must tell their healthcare provider right away.
Patients must not receive Xolair if they have ever had an allergic reaction to a Xolair injection. Patients should not use Xolair if they are allergic to any of its ingredients.
In clinical studies, a variety of cancer types, including breast, skin, prostate, and parotid (a type of salivary gland), were reported in more patients who received Xolair than in patients who did not receive Xolair.
Xolair is not a rescue medicine and should not be used to treat sudden asthma attacks.
Xolair is not a substitute for the medicines patients are already taking. Patients must not change or stop taking any of their other asthma medicines unless their doctor tells them to do so.
Some patients on Xolair may have an abnormal increase in eosinophils (a type of white blood cell) in the blood or tissues, sometimes causing an inflammation of blood vessels which can lead to rash, worsening of respiratory symptoms, heart trouble, and/or nerve pain and weakness.
Joint inflammation or pain, rash, fever, and swollen lymph nodes have been seen in some patients taking Xolair after the first or subsequent injections. Patients should talk to their doctor if they have experienced any of these signs and symptoms.
In allergic asthma studies, the most commonly seen side effects occurring more frequently in patients receiving Xolair than in patients who received placebo (an injection with no active medicine) were joint pain, pain (general), leg pain, tiredness (fatigue), dizziness, fracture, arm pain, itching, inflammation of the skin, and earache.
