Mozobil - patient leaflet, side effects, dosage

1. What Mozobil is and what it is used for

Mozobil contains the active substance plerixafor which blocks a protein on the surface of blood stem cells. This protein “ties” blood stem cells to the bone marrow. Plerixafor improves the release of stem cells into the blood stream (mobilisation). The stem cells can then be collected by a machine that separates blood constituents (apheresis machine), and subsequently frozen and stored until your transplant.

If mobilisation is poor, Mozobil is used to help collect blood stem cells from the patient, for collection, storage and reintroduction (transplantation),

• In adults who have lymphoma (a cancer of the white blood cells) or multiple myeloma (a cancer that affects plasma cells in the bone marrow).
• In children age 1 to less than 18 years of age with lymphoma or solid tumours.

2. What you need to know before you use Mozobil

Do not use Mozobil

• if you are allergic to plerixafor or any of the other ingredients of this medicine (listed in section 6).

Warnings and precautions

Talk to your doctor before using Mozobil.

Tell your doctor:

• if you have or have had any heart problems.
• if you have kidney problems. Your doctor may adjust the dose.
• if you have high white blood cell counts.
• if you have low platelet counts.
• if you have a history of feeling faint or lightheaded on standing or sitting or have fainted before upon injections.

Your doctor may perform regular blood tests to monitor your blood cell count.

It is not recommended to use Mozobil for stem cell mobilisation if you have leukaemia (a cancer of the blood or bone marrow).

Other medicines and Mozobil

Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines.

Pregnancy and breast-feeding

You should not use Mozobil if you are pregnant, since there is no experience with Mozobil in pregnant women. It is important to tell your doctor if you are, think you may be or are planning to become pregnant. It is recommended to use contraception if you are of child-bearing age.

You should not breast-feed if you are using Mozobil, since it is not known if Mozobil is excreted in human milk.

Driving and using machines

Mozobil may cause dizziness and fatigue. Therefore, you should avoid driving if you feel dizzy, tired or unwell.

Mozobil contains sodium

This medicine contains less than 1 mmol sodium (23 mg) per dose, i.e. essentially ‘sodium-free’.

3. How to use Mozobil

Your medicine will be injected by a doctor or a nurse.

You will first receive G-CSF, then you will be given Mozobil

Mobilisation will be started by first giving you another medicine called G-CSF (granulocyte-colony stimulating factor). G-CSF will help Mozobil to work properly in your body. If you want to know more about G-CSF ask your doctor and read the corresponding package leaflet.

How much Mozobil is given?

The recommended adult dose is either a 20 mg (fixed dose) or 0.24 mg/kg body weight/day.

The recommended dose for children, 1 to less than 18 years of age is 0.24 mg/kg of body weight/day.

Your dose will depend on your body weight, which should be measured the week before you receive your first dose. If you have moderate or severe kidney problems, your doctor will reduce the dose.

How is Mozobil given?

Mozobil is given by subcutaneous injection (under your skin).

When is Mozobil given for the first time?

You will receive your first dose 6 to 11 hours before apheresis (collection of your blood stem cells).

How long will Mozobil be given?

Treatment lasts 2 to 4 consecutive days (in some cases up to 7 days), until enough stem cells have been collected for your transplant. In a few cases, enough stem cells may not be collected, and the collection attempt will be stopped.
