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).

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

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.

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

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

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.

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.

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

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

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.

• you have pain in the upper left abdomen (belly) or your left shoulder

In clinical trials, patients with risk factors for a heart attack uncommonly suffered heart attacks after being given Mozobil and G-CSF. Please inform your doctor immediately if you experience chest discomfort.

Pins and needles and numbness are common in patients being treated for cancers. About one in five patients suffered from these feelings. However, these effects do not seem to occur more frequently when you use Mozobil.

You may also have an increase in white blood cells count (leucocytosis), in your blood tests.
