1) WHAT MERCAPTOPURINE IS AND WHAT IT IS USED
FOR
Mercaptopurine tablets contain a medicine called
mercaptopurine.
This belongs to a group of medicines called cytotoxics (also
called chemotherapy). Mercaptopurine is used to treat
leukaemia (cancer of the blood). It works by reducing the
number of new blood cells your body makes.
Mercaptopurine is used for:
• Acute myelogenous leukaemia (also called acute
myeloid leukaemia or AML) - a fast-growing disease
that increases the number of white blood cells
produced by the bone marrow. This can cause
infections and bleeding.
• Acute lymphoblastic leukaemia (also called acute
lymphocytic leukaemia or ALL) - a fast-growing
disease which increases the number of immature white
blood cells. These immature white blood cells are
unable to grow and work properly. They therefore
cannot fight infections and may cause bleeding.
• Chronic granulocytic leukaemia (also called chronic
myeloid leukaemia) - a disease that increases the
number of white blood cells. This can cause infections
and bleeding.
Ask your doctor if you would like more explanation about
these diseases.
2) BEFORE YOU TAKE MERCAPTOPURINE
Do not take Mercaptopurine if:
• You are allergic (hypersensitive) to mercaptopurine or
any of the other ingredients of Mercaptopurine tablets
(See section 6: Further information)
Do not take if the above applies to you. If you are not sure,
talk to your doctor or pharmacist before taking
Mercaptopurine.
Take special care with Mercaptopurine
Before you take Mercaptopurine, tell your doctor or
pharmacist if:
• you have a liver problem; your doctor will monitor your
liver function
• you have a condition where your body produces too
little of something called TPMT or ‘thiopurine
methyltransferase’.
If you are not sure if any of the above apply to you, talk to
your doctor, nurse or pharmacist before taking
Mercaptopurine.

Taking other medicines
Please tell your doctor or pharmacist if you are taking or have
recently taken any other medicines, including medicines
obtained without a prescription. This includes herbal
medicines.
In particular, tell your doctor or pharmacist if you are taking
any of the following:
• other cytotoxic drugs (chemotherapy) - when used with
Mercaptopurine there is a greater chance of side
effects, such as breathing problems
• allopurinol (used to treat gout)
• warfarin (used to thin the blood)
• olsalazine or mesalazine (used for a bowel problem
called ulcerative colitis)
• sulfasalazine (used for rheumatoid arthritis or
ulcerative colitis).
Having vaccines while you are taking Mercaptopurine
If you are going to have a vaccination speak to your doctor or
nurse before you have it. This is because some vaccines (like
polio, measles, mumps and rubella) may give you an infection
if you have them whilst you are taking Mercaptopurine.
Pregnancy and breast-feeding
Do not take Mercaptopurine if you are planning to have a
baby. This applies to both men and women. Mercaptopurine
may harm your sperm or eggs. Reliable contraceptive
precautions must be taken to avoid pregnancy whilst you or
your partner are taking these tablets. Ask your doctor for
advice.
If you are already pregnant, it is important to talk to your
doctor before taking Mercaptopurine.
Do not breast-feed while taking Mercaptopurine. Ask your
doctor or midwife for advice.
Important information about some of the ingredients of
Mercaptopurine
Mercaptopurine tablets contain lactose. If you have been told
by your doctor that you have an intolerance to some sugars,
contact your doctor before you take Mercaptopurine tablets.
3) HOW TO TAKE MERCAPTOPURINE
Mercaptopurine should only be given to you by a specialist
doctor who is experienced in treating blood problems.
Always take Mercaptopurine exactly as your doctor has told
you. It is important to take your medicine at the right times.
The label on your pack will tell you how many tablets to take
and how often to take them. If the label doesn’t say or if you
are not sure, ask your doctor, nurse or pharmacist.
• Swallow your tablets whole with a glass of water.
• If you need to break your tablet in half, do not inhale
any tablet powder. Wash your hands afterwards.
• When you take Mercaptopurine your doctor will take
regular blood tests. This is to check the number and
type of cells in your blood and to ensure your liver is
working correctly.
• Your doctor may also ask for other blood and urine
tests to monitor your uric acid levels. Uric acid is a
natural body chemical, levels of which can rise while
taking Mercaptopurine.
• Your doctor may sometimes change your dose of
Mercaptopurine as a result of these tests.
The dose of Mercaptopurine you are given will be worked out
by your doctor based on:
• your body size (surface area)

the results of your blood tests
• The usual starting dose for adults and children is 2.5
mg per kilogram of your body weight each day.
• Elderly patients will have their kidney and liver function
tested and if necessary the dose may need to be
reduced.
Continued overleaf

If you take more Mercaptopurine than you should
If you take more Mercaptopurine than you should, tell your
doctor immediately or go to a hospital straight away. Take the
medicine pack with you.
If you forget to take Mercaptopurine
Tell your doctor. Do not take a double dose to make up for
a forgotten dose.
4) POSSIBLE SIDE EFFECTS
Like all medicines, Mercaptopurine can cause side effects,
although not everybody gets them.
If you get any of the following, talk to your specialist
doctor or go to hospital straight away:
• allergic reaction, the signs may include:
- skin rashes
- high temperature
- joint pain
- swollen face
• any signs of fever or infection (sore throat, sore mouth
or urinary problems)

mean that too few blood cells of a particular type are
being produced
• if you suddenly feel unwell (even with a normal
temperature)
• any yellowing of the whites of the eyes or skin
(jaundice)
• if you have diarrhoea
• if you feel sick (nausea) or you are sick (vomiting).
