What is in this leaflet
This leaflet answers some common questions about MYLOTARG. It does not contain all the available information. It does not take the place of talking to your doctor or pharmacist.

What MYLOTARG is used for
MYLOTARG contains the active ingredient gemtuzumab ozogamicin. It belongs to a group of medicines called antineoplastic agents that target cancer cells.
MYLOTARG is used to treat patients aged 15 years and above with acute myeloid leukaemia (AML). AML is a cancer of the blood and bone marrow in which the bone marrow makes immature white blood cells in high numbers. These abnormal cells crowd the bone marrow, preventing it from making normal blood cells.
This medicine works by stopping the abnormal growth of these cells and destroying them.
Ask your doctor if you have any questions about why this medicine has been prescribed for you.
Your doctor may have prescribed it for another reason.
This medicine is available only with a doctor's prescription.

How MYLOTARG is given
MYLOTARG is given in "cycles". The first MYLOTARG treatment cycle is made up of a single MYLOTARG dose given on Day 1, Day 4 and Day 7 in Week 1 (Induction cycle).
The second and third MYLOTARG treatment cycles are made up of a single MYLOTARG dose given on Day 1 (Consolidation cycle).
A doctor or nurse will give you your MYLOTARG dose gradually over 2 hours through a drip in your vein (intravenous infusion).
How much is given
Your doctor will calculate how much you need to be given.
This will depend on your height and weight and may also depend on your condition and how you have responded to previous treatment.
Medicines given before each cycle
Before each treatment with MYLOTARG you will be given other medicines (premedication) to help reduce symptoms such as fever, chills or hot flush, known as infusion reactions, and other possible side effects.
How long it is given
You will receive between one and three cycles of MYLOTARG in combination with chemotherapy. The first cycle is called Induction. The second and third cycles are called Consolidation. If the medicine works well after the Induction cycle, you may receive the two Consolidation cycles. If you do not respond to the medicine after the first cycle your treatment will be stopped.
Your doctor will discuss with you how long your treatment will last.
If you forget a treatment
If you miss a treatment, contact your doctor or nurse as soon as possible to make a new appointment.
If you take too much (overdose)
It is unlikely that you will be given too much MYLOTARG, as your dose will be calculated and given to you in a specialised setting under the supervision of a doctor.
If an overdose is suspected, immediately telephone your doctor or Poisons Information Centre (telephone 13 11 26) for advice, or go to Accident and Emergency at the nearest hospital.
You may need urgent medical attention.
