What Xolair Is And What It Is Used For

Xolair is used to prevent asthma from getting worse by controlling symptoms of severe allergic asthma in patients (6 years of age and older) who are already receiving asthma medication, but whose asthma symptoms are not well controlled by medicines such as high-dose steroid inhalers or beta-agonist inhalers.

Xolair works by blocking a substance called immunoglobulin E (IgE), which is produced by the body. IgE plays a key role in causing allergic asthma.

Before You Are Given Xolair

You should not be given Xolair

  • if you are allergic (hypersensitive) to omalizumab or any of the other ingredients of Xolair. The ingredients are listed in section 6 of this leaflet.

If you think you may be allergic to any of the ingredients, tell your doctor since you should not be given Xolair.

Take special care with Xolair

Tell your doctor before you are given Xolair:

  • if you have kidney or liver problems.
  • if you have a disorder where your own immune system attacks parts of your own body (autoimmune disease).
  • if you live in a region where infections caused by parasites are common or if you are travelling to such a region as Xolair may weaken your resistance to such infections.

Xolair contains a protein, and proteins can cause serious allergic reactions in some people. Signs include rash, difficulty in breathing, swelling or feeling faint. If you have an allergic reaction after taking Xolair, contact a doctor as soon as you can.

Xolair does not treat acute asthma symptoms, such as a sudden asthma attack.

Xolair is not meant to prevent or treat other allergy-type conditions, such as sudden allergic reactions, hyperimmunoglobulin E syndrome (an inherited immune disorder), aspergillosis (a fungus-related lung disease), food allergy, allergic skin rash or hay fever.

Children (under 6 years of age)

Do not give Xolair to children under 6 years of age. There are not enough data in this group.

Taking other medicines

Please tell your doctor or pharmacist if you are taking or have recently taken any other medicines, including medicines obtained without a prescription.

This is especially important if you are taking:

  • medicines to treat an infection caused by a parasite, as Xolair may reduce the effect of your medicines,
  • inhaled corticosteroids and other medicines for allergic asthma.

Pregnancy and breast-feeding

You should not take Xolair when you are pregnant.

If you plan to become pregnant, tell your doctor before starting treatment with Xolair. Your doctor will discuss with you the benefits and potential risks of being given this medicine during pregnancy.

If you become pregnant while being treated with Xolair, tell your doctor immediately.

You should not take Xolair when you are breast-feeding.

Driving and using machines

Xolair may make you feel dizzy, sleepy or faint. If this happens to you, do not drive or use machines.

Important information about some of the ingredients of Xolair

If you are a diabetic or have been told by your doctor that you have an intolerance to some sugars, talk to your doctor before taking Xolair. Xolair contains sucrose.

How Xolair Is Given

Xolair is given to you by a doctor or nurse as an injection just under the skin.

Your doctor will work out how much Xolair you need and how often you will be given it. This depends on your body weight and the results of a blood test carried out before the start of the treatment to measure the amount of IgE in your blood.

Follow carefully all instructions given by your doctor or nurse.

How much you will be given

You will be given 1 to 4 injections at a time, either every two weeks, or every four weeks.

Carry on taking your current asthma medicine during Xolair treatment. Do not stop taking any asthma medicines without talking to your doctor.

You may not see an immediate improvement in your asthma after beginning Xolair therapy. It usually takes several weeks to have the full effect.

If a dose of Xolair is missed

Contact your doctor or hospital as soon as possible to re-schedule your appointment.

If you stop treatment with Xolair

Interrupting or stopping the treatment with Xolair may cause your asthma symptoms to come back.
