Patient leaflet - Xolair 150 mg powder and solvent for solution for injection
1. What Xolair is and what it is used for
Xolair contains the active substance omalizumab. Omalizumab is a man-made protein that is similar to natural proteins produced by the body. It belongs to a class of medicines called monoclonal antibodies.
Xolair is used for the treatment of:
- allergic asthma
- chronic rhinosinusitis (inflammation of the nose and sinuses) with nasal polyps
- chronic spontaneous urticaria (CSU)
Allergic asthma
This medicine is used to prevent asthma from getting worse by controlling symptoms of severe allergic asthma in adults, adolescents and children (6 years of age and older) who are already receiving asthma medicine, but whose asthma symptoms are not well controlled by medicines such as high-dose steroid inhalers and beta-agonist inhalers.
Chronic rhinosinusitis with nasal polyps
This medicine is used to treat chronic rhinosinusitis with nasal polyps in adults (18 years of age and older) who are already receiving intranasal corticosteroids (corticosteroid nasal spray), but whose symptoms are not well controlled by these medicines. Nasal polyps are small growths on the lining of the nose. Xolair helps to reduce the size of the polyps and improves symptoms including nasal congestion, loss of sense of smell, mucus in the back of the throat and runny nose.
Chronic spontaneous urticaria (CSU)
This medicine is used to treat chronic spontaneous urticaria in adults and adolescents (12 years of age and older) who are already receiving antihistamines but whose CSU symptoms are not well controlled by these medicines.
Xolair works by blocking a substance called immunoglobulin E (IgE), which is produced by the body. IgE contributes to a type of inflammation that plays a key role in causing allergic asthma, chronic rhinosinusitis with nasal polyps and CSU.
2. What you need to know before you are given Xolair
You should not be given Xolair:
- if you are allergic to omalizumab or any of the other ingredients of this medicine (listed in section 6).
If you think you may be allergic to any of the ingredients, tell your doctor as you should not be given Xolair.
Warnings and precautions
Talk to 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 are travelling to a region where infections caused by parasites are common - Xolair may weaken your resistance to such infections.
- if you have had a previous severe allergic reaction (anaphylaxis) for example resulting from a medicine, an insect bite or food.
Xolair does not treat acute asthma symptoms, such as a sudden asthma attack. Therefore Xolair should not be used to treat such symptoms.
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, eczema or hay fever because Xolair has not been studied in these conditions.
Look out for signs of allergic reactions and other serious side effects
Xolair can potentially cause serious side effects. You must look out for signs of these conditions while you use Xolair. Seek medical help immediately if you notice any signs indicating a possible serious side effect. Such signs are listed under “Serious side effects” in section 4. The majority of severe allergic reactions occur within the first 3 doses of Xolair.
Children and adolescents
Allergic asthma
Xolair is not recommended for children under 6 years of age. Its use in children under 6 years of age has not been studied.
Chronic rhinosinusitis with nasal polyps
Xolair is not recommended for children and adolescents under 18 years of age. Its use in patients under 18 years of age has not been studied.
Chronic spontaneous urticaria (CSU)
Xolair is not recommended for children under 12 years of age. Its use in children under 12 years of age has not been studied.
Other medicines and Xolair
Tell your doctor, pharmacist or nurse if you are taking, have recently taken or might take any other medicines.
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
If you are pregnant, think you may be pregnant or are planning to have a baby, ask your doctor for advice before using this medicine. 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.
Xolair may pass into breast milk. If you are breast-feeding or plan to breast-feed, ask your doctor for advice before using this medicine.
Driving and using machines
It is unlikely that Xolair will affect your ability to drive and use machines.
3. How Xolair is given
Instructions on how to use Xolair are given in the section “Information for the healthcare professional”.
Xolair is given to you by a doctor or nurse as an injection just under the skin (subcutaneously).
Follow carefully all instructions given by your doctor or nurse.
How much you will be given
Allergic asthma and chronic rhinosinusitis with nasal polyps
Your doctor will decide 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.
You will be given 1 to 4 injections at a time, either every two weeks, or every four weeks.
Keep taking your current asthma and/or nasal polyps medicine during Xolair treatment. Do not stop taking any asthma and/or nasal polyps medicine without talking to your doctor.
You may not see an immediate improvement after beginning Xolair therapy. In patients with nasal polyps effects have been seen 4 weeks after the start of the treatment. In asthma patients it usually takes between 12 and 16 weeks to have the full effect.
Chronic spontaneous urticaria (CSU)
You will be given two 150 mg injections at a time every four weeks.
Keep taking your current medicine for CSU during Xolair treatment. Do not stop taking any medicine without talking to your doctor.
Use in children and adolescents
Allergic asthma
Xolair can be given to children and adolescents aged 6 years and older, who are already receiving asthma medicine, but whose asthma symptoms are not well controlled by medicines such as high dose steroid inhalers and beta-agonist inhalers. Your doctor will work out how much Xolair your child needs and how often it needs to be given. This will depend on your child’s weight and the results of a blood test carried out before the start of the treatment to measure the amount of IgE in his/her blood.
Chronic rhinosinusitis with nasal polyps
Xolair should not be given to children and adolescents under 18 years of age.
Chronic spontaneous urticaria (CSU)
Xolair can be given to adolescents aged 12 years and older, who are already receiving antihistamines but whose CSU symptoms are not well controlled by these medicines. The dose for adolescents aged 12 years and above is the same as for adults.
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
Do not stop treatment with Xolair unless your doctor tells you to. Interrupting or stopping the treatment with Xolair may cause your symptoms to come back.
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 have any further questions on the use of this medicine, ask your doctor, pharmacist or nurse.

INFORMATION FOR THE HEALTHCARE PROFESSIONAL
The following information is intended for healthcare professionals only:
The lyophilised medicinal product takes 15-20 minutes to dissolve, although in some cases it may take longer. The fully reconstituted medicinal product will appear clear to slightly opalescent, colourless to pale brownish-yellow and may have a few small bubbles or foam around the edge of the vial. Because of the viscosity of the reconstituted medicinal product care must be taken to withdraw all of the medicinal product from the vial before expelling any air or excess solution from the syringe in order to obtain the 1.2 ml.
To prepare Xolair 150 mg vials for subcutaneous administration, please adhere to the following instructions:
- 1. Draw 1.4 ml of water for injections from the ampoule into a syringe equipped with a large-bore 18-gauge needle.
- 2. With the vial placed upright on a flat surface, insert the needle and transfer the water for injections into the vial containing the lyophilised powder using standard aseptic techniques, directing the water for injections directly onto the powder.
- 3.
Keeping the vial in an upright position, vigorously swirl it (do not shake) for approximately
1 minute to evenly wet the powder.
- 4.
To aid in dissolution after completing step 3, gently swirl the vial for 5-10 seconds approximately every 5 minutes in order to dissolve any remaining solids.
Note that in some cases it may take longer than 20 minutes for the powder to dissolve completely. If this is the case, repeat step 4 until there are no visible gel-like particles in the solution.
When the medicinal product is fully dissolved, there should be no visible gel-like particles in the solution. Small bubbles or foam around the edge of the vial are common. The reconstituted medicinal product will appear clear to slightly opalescent, colourless to pale brownish-yellow. Do not use if solid particles are present.
- 5.
Invert the vial for at least 15 seconds in order to allow the solution to drain towards the stopper.
Using a new 3-ml syringe equipped with a large-bore, 18-gauge needle, insert the needle into the inverted vial. Keeping the vial inverted position the needle tip at the very bottom of the solution in the vial when drawing the solution into the syringe. Before removing the needle from the vial, pull the plunger all the way back to the end of the syringe barrel in order to remove all of the solution from the inverted vial.
- 6. Replace the 18-gauge needle with a 25-gauge needle for subcutaneous injection.
- 7.
Expel air, large bubbles, and any excess solution in order to obtain the required 1.2 ml dose. A thin layer of small bubbles may remain at the top of the solution in the syringe. Because the solution is slightly viscous, it may take 5-10 seconds to administer the solution by subcutaneous injection.
The vial delivers 1.2 ml (150 mg) of Xolair. For a 75 mg dose, draw up 0.6 ml into the syringe and discard the remaining solution.
- 8.
The injections are administered subcutaneously in the deltoid region of the arm, the lower abdomen
(but not the area 5 centimetres around the navel) or the thigh.
