1

What Puri-nethol is and what it is used for

Puri-nethol tablets contain the active substance called 6-puri-nethol.
6-puri-nethol belongs to a group of medicines called cytotoxics (also called
chemotherapy) and works by reducing the number of new blood cells your
body makes. Puri-nethol is used to treat cancer of the blood (leukaemia) in
adults, adolescents and children.

2

What you need to know before you take
Puri-nethol

Do not take Puri-nethol:
If you are allergic to 6-puri-nethol or any of the other ingredients of this
medicine (listed in section 6).
Warnings and precautions
Talk to your doctor or pharmacist before taking Puri-nethol:
* If you have recently received, or are due to receive, a vaccination
(vaccine). If you take Puri-nethol, you should not have a live organism
vaccine (for example; flu vaccine, measles vaccine, BCG vaccine, etc.)
until advised it is safe to do so by your doctor. This is because some
vaccines may give you an infection if you receive them while you are
taking Puri-nethol If you have reduced liver function or liver damage
* If you have reduced liver function or liver damage
* If you have a genetic condition called TPMT (thiopurine methyltransferase)
deficiency
* If you have an allergy to a medicine called azathioprine (also used to treat
cancer)
* If you have a kidney problem.
* Tell your doctor whether you have, or have not, had chicken pox, shingles
or hepatitis B (a liver disease caused by a virus).
* If you have a genetic condition called Lesch-Nyhan Syndrome
If you are receiving immunosuppressive therapy, taking Puri-nethol could put
you at greater risk of:
* tumours, including skin cancer. Therefore, when taking Puri-nethol,
avoid excessive exposure to sunlight, wear protective clothing and use
protective sunscreen with a high protection factor.
* lymphoproliferative disorders:
- treatment with Puri-nethol increases your risk of getting a type of
cancer called lymphoproliferative disorder. With treatment regimen
containing multiple immunosuppressants (including thiopurines), this may
lead to death.
- a combination of multiple immunosuppressants, given concomitantly
increases the risk of disorders of the lymph system due to a viral
infection (Epstein-Barr virus (EBV) - associated lymphoproliferative
disorders).
Taking Puri-nethol could put you at greater risk of:
* developing a serious condition called Macrophage Activation Syndrome
(excessive activation of white blood cells associated with inflammation),
which usually occurs in people who have certain types of arthritis.
Blood tests
with Puri-nethol may affect your bone marrow. This means
* Treatment
you may have a reduced number of white blood cells, platelets and (less
commonly) red blood cells in your blood. Your doctor will carry out blood
tests daily when you are at the beginning of your treatment (induction) and
at least weekly when you are further along into your treatment
(maintenance). This is in order to monitor the levels of these cells in your
blood. If you stop treatment early enough, your blood cells will return to
normal.

Other laboratory tests
* Additional laboratory tests (urine, blood, etc.) may also be carried out as
directed by your doctor.
Liver function
* Puri-nethol is toxic to your liver. Therefore, your doctor will carry out
weekly liver function tests when you are taking Puri-nethol. If you
already have liver disease, or if you are taking other medications which
may affect your liver, your doctor will carry out more frequent tests. If you
notice the whites of your eyes or your skin turn yellow (jaundice) tell your
doctor immediately as you may need to stop your treatment immediately.
Infections
* When you are taking Puri-nethol you may be more likely to get
infections caused by viruses, bacteria and fungus and your reaction to
these infections may be more severe than people who are not being taking
Puri-nethol. If you think you have an infection, talk to your doctor
immediately.
Children and adolescents
Low blood sugar levels (sweating more than usual, nausea, dizziness,
confusion, etc.) have been reported in some children receiving Puri-nethol;
however, most of the children were under the age of six years old and had a
low body weight. If you are not sure if any of the above applies to you, talk
to your doctor or pharmacist before taking Puri-nethol.
Other medicines and Puri-nethol
Tell your doctor or pharmacist if you are taking, have recently taken or might
take any other medicines. In particular, tell your doctor or pharmacist if you
are taking any of the following:
* Ribavirin (used to treat viruses)
* Other cytotoxic medicines (chemotherapy - used to treat cancer)
* Allopurinol, thiopurinol, oxipurinol or febuxostat (used to treat gout)
* Olsalazine (used to treat a bowel problem called ulcerative colitis)
* Mesalazine (used to treat Crohn’s Disease and ulcerative colitis)
* Sulfasalazine (used to treat rheumatoid arthritis or ulcerative colitis)
* Methotrexate (used to treat rheumatoid arthritis or severe psoriasis)
* Infliximab (used to treat Crohn’s Disease and ulcerative colitis, rheumatoid
arthritis, ankylosing spondylitis or severe psoriasis)
* Warfarin or acenocoumarol (used to ‘thin’ the blood)
Having vaccines while you are taking Puri-nethol
If you are going to have a vaccination speak to your doctor or nurse before
you have it. If you take Puri-nethol, you should not have a live vaccine (for
example; flu vaccine, measles vaccine, BCG vaccine, etc.) until advised it is
safe to do so by your doctor. This is because some vaccines may give you
an infection if you have them whilst you are taking Puri-nethol.
Puri-nethol with food and drink
You can take Puri-nethol with food or on an empty stomach but the choice of
method should be consistent from day to day. You should take your medicine
at least 1 hour before or 2 hours after having milk or dairy products.
Pregnancy and breast-feeding
If you are pregnant or breast-feeding, think you may be pregnant or are
planning to have a baby, ask your doctor for advice before taking this
medicine.
Pregnancy
Treatment with Puri-nethol is not recommended during pregnancy,
particularly in the first trimester (three months) because it may cause
damage to the foetus. If you are pregnant your doctor will consider the risks
and benefits to you and your baby before prescribing Puri-nethol for you.
If you or your partner are taking Puri-nethol, you must use a reliable form of
contraception to avoid pregnancy for the whole course of Puri-nethol
treatment and for at least 3 months after receiving the last dose of
Puri-nethol. This applies to both men and women.
Breast-feeding
Is it recommended that you do not breast-feed when you are taking
Puri-nethol.
Driving and using machines
It is not expected that Puri-nethol will affect your ability to drive or use
machines, but no studies have been done to confirm this.
Puri-nethol 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 Puri-nethol tablets.

your liver is working correctly
Your doctor may also ask for other blood and urine tests to monitor how
your kidneys are working and to measure uric acid levels. Uric acid is a
natural substance made in your body and levels of uric acid can rise while
you are taking Puri-nethol. High levels of uric acid may damage your
kidneys
Your doctor may sometimes change your dose of Puri-nethol as a
result of these tests.

Always take Puri-nethol exactly as your doctor or pharmacist has told you.

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 does not
say or if you are not sure, ask your doctor, nurse or pharmacist.
The usual dose for adults and children is 2.5 mg per kilogram of your body
weight each day (or alternatively 50 to 75 mg per m2 of your body surface
area each day). Your doctor will calculate and adjust your dose based on
your body weight, results of your blood tests, whether or not you are taking
other chemotherapy medicines and your kidney and liver function.

Very rare (may affect up to 1 in 10,000 people)
* Blood cancer
* Cancer of the spleen and liver (in patients with a condition called
Inflammatory Bowel Disease)
* Ulcers in the intestines; symptoms may include abdominal pain and
bleeding
* Low sperm count in men
Not known (frequency cannot be estimated from the available data)
