What is Mitoxantrone® used for?

Mitoxantrone® (sometimes spelt mitozantrone) is a chemotherapy drug for the treatment of androgen independent (hormone refractory) metastatic prostate cancer.

Mitoxantrone® belongs to a group of medicines called antineoplastic or cytotoxic medicines. You may also hear these being called chemotherapy medicines.

Mitoxantrone® is thought to work by interfering with the growth of cancer cells, which slows their growth and destroys them. The growth of normal cells in other parts of your body may also be affected.

Your doctor may have prescribed this medicine for another reason. Ask your doctor if you have any questions about why DBLTM Mitoxantrone Hydrochloride Injection Concentrate® has been prescribed for you.

This medicine is available only with a doctor’s prescription. DBLTM Mitoxantrone Hydrochloride Injection Concentrate® is not recommended for use in children as there is not enough information on its effects in children.

How is Mitoxantrone® given?

Mitoxantrone® is delivered as an infusion (drip) into your veins, over 3 to 5 minutes.

Mitoxantrone® must only be given by a doctor or nurse.

Mitoxantrone® is usually given once every 21 days, or it may be given over 2 to 5 days, depending on your condition. This is called ‘one cycle’ of chemotherapy. Your doctor will decide how many of these cycles you will need. The time between each dose of Mitoxantrone® may change depending on the results of your blood tests.

You may also notice a blue/green colour around the whites of your eyes. DO NOT panic – this is quite normal and is nothing to be concerned about.

Treatment with Mitoxantrone® causes the breakdown of tumour cells and this may affect how your liver and kidneys work. Your doctor will arrange regular blood tests to detect any changes.
