XOLAIR should always be injected in a doctor's office. You should read the Medication Guide before starting XOLAIR treatment and before each subsequent treatment.

A severe allergic reaction called anaphylaxis has happened in some patients after they received XOLAIR. Anaphylaxis is a life-threatening condition and can lead to death. Seek emergency medical treatment right away if symptoms occur. Signs and symptoms of anaphylaxis include:

  • 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

You should not receive XOLAIR if you have ever had an allergic reaction to a XOLAIR injection. Do not use XOLAIR if you are allergic to any of its ingredients.

In clinical studies 0.5% of patients receiving XOLAIR developed cancer, compared to 0.2% of patients receiving placebo (an injection with no active medicine).

In patients >12 years of age, the most commonly observed side effects in asthma studies that had a >1% difference between XOLAIR and placebo were joint pain (8%), pain (general) ( 7%), leg pain (4%), tiredness (fatigue) (3%), dizziness (3%), fracture (2%), arm pain (2%), itching (2%), inflammation of the skin (2%), and earache (2%).

In asthma studies, the most common side effects in patients, who either needed to stop XOLAIR or needed medical attention, were injection site reaction (45%), viral infections (23%), upper respiratory tract infection (20%), sinusitis (16%), headache (15%), and sore throat (11%). These side effects were seen at the same rates in XOLAIR-treated patients as in patients in the control group who received placebo.

XOLAIR is not a rescue medicine and should not be used to treat sudden asthma attacks.

XOLAIR is not a substitute for the medicines you are already taking. Do not change or stop taking any of your other asthma medicines unless your doctor tells you to do so. You may not see an immediate improvement in your asthma when beginning XOLAIR therapy.

Talk to your doctor for more information and if you have any questions about your treatment.
