What Xolair is used for

Allergic asthma
Xolair is used to prevent or relieve the symptoms of allergic asthma in people who are already using preventer puffers containing steroids. Asthma is a disease where the lining of the lungs becomes inflamed (red and swollen), making it difficult to breathe. This may be due to a reaction to house dust mites, smoke or other irritants.

Xolair contains omalizumab, a monoclonal antibody produced by recombinant DNA technology. It works by blocking a substance produced by the body called immunoglobulin E (or IgE). IgE is involved in causing symptoms of asthma. Your doctor will measure the amount of IgE in your blood before starting your treatment with Xolair.

This medicine can be used in adults and in children aged 6 years or over in allergic asthma.

Chronic Spontaneous Urticaria (CSU)
Xolair is used to treat Chronic Spontaneous Urticaria in adults and adolescents (12 years of age and older) whose CSU symptoms are not well controlled by antihistamines.

Xolair works by blocking a substance called immunoglobulin E (also known as IgE) which is produced by your body. As a consequence the activity of specific receptors and/or cells in your body which play a key role in causing chronic spontaneous urticaria are reduced. This leads to a reduction of your symptoms, like itching and hives.

Elderly patients are given the same dosage as younger adults.

Ask your doctor if you have any questions about why Xolair has been prescribed for you. Your doctor may have prescribed this medicine for another reason.

Xolair is only available with a doctor's prescription. It is not addictive.

Before you have Xolair

When you must not have it

Do not have Xolair if you have an allergy to:

  • omalizumab (the active ingredient in Xolair) or any of the other ingredients listed at the end of this leaflet.

Some of the symptoms of an allergic reaction may include shortness of breath, wheezing or difficulty breathing, swelling of the face, lips, tongue or other parts of the body, rash, itching or hives on the skin.

Before you have it

Tell your doctor if you get severe allergic reactions (called anaphylaxis) to any medicines, foods, dyes, preservatives, bee stings, insect bites, latex etc.

Tell your doctor if you have any of the following medical conditions:

  • hyper-IgE syndrome, a condition where you have high levels of IgE in your blood
  • an allergic skin condition
  • a lung problem caused by a fungus called Aspergillus
  • an infection caused by a parasite
  • a low platelet count (thrombocytopenia).

There is no information on the use of Xolair in people who have any of the above conditions. If you are not sure whether any of these conditions apply to you, your doctor can advise you.

Tell your doctor if you have kidney or liver problems. Talk to your doctor about using Xolair if you have kidney or liver problems.

Tell your doctor if you are pregnant or intend to become pregnant or wish to breast-feed your baby. There is not much information on the use of Xolair during pregnancy or breast-feeding. If it is necessary for you to have this medicine, your doctor will discuss with you the benefits and risks involved.

Tell your doctor, if you ever had an allergic reaction to latex (information specific to the needle cap of the pre-filled syringe).

If you have not told your doctor about any of these things, tell him/her before you have Xolair.

Taking other medicines

Tell your doctor if you are taking any other medicines, including any that you buy without a prescription from a pharmacy, supermarket or health food shop.

Xolair has been used together with other common medicines for asthma, as well as H1 or H2 antihistamines and LTRAs for chronic spontaneous urticaria. It is possible that some medicines and Xolair could interfere with each other. Your doctor or pharmacist can advise you.

How Xolair is given

This medicine is given as a subcutaneous injection. That means that it is injected into the fat layer just under the skin. Your doctor or nurse will give the injections. The injections are usually given in the upper arm or thigh.

How much is given

Allergic asthma
Your doctor will work out how much Xolair you need and how often you will be given the injections. This will depend on your body weight and the amount of IgE measured in your blood before the start of treatment.

The recommended dose of Xolair ranges from 75 to 750 mg of Xolair every four weeks. Some doses are split into two injections given fortnightly, depending on your body weight and IgE levels. You will need to continue your current asthma medicines when you start Xolair treatment but after 16 weeks, if your symptoms are well controlled, your doctor may be able to reduce or stop other asthma medicines that you are taking. Your doctor will discuss this with you.

Chronic spontaneous urticaria
You will be given 1 or 2 injections of 150 mg at a time every four weeks.

Continue taking your current medicine for CSU during Xolair treatment. Do not stop taking any medicine without talking to your doctor first.

However, if you are being treated for CSU, your doctor may stop Xolair treatment from time to time so that your symptoms can be assessed. Follow your doctor's instructions.

If you are given too much (Overdose)

If you think that you may have been given too much Xolair, immediately tell your doctor or nurse.

No cases of overdose with this medicine have been reported.

While you are having Xolair

Things you must do

If you become pregnant while having treatment with Xolair, tell your doctor.

Tell your doctor if you notice anything else that is making you feel unwell. Other side effects not listed above may happen in some people.
