Information for the user
Cytarabine 20 mg/ml Injection

Cytarabine Injection is an anti-cancer medicine. Treatment with an anti-cancer
medicine is sometimes called cancer chemotherapy.
Cytarabine Injection is used to treat some types of leukaemia (cancer affecting
the blood) and lymphomas (cancer of the lymph glands). It may be used in
combination with other anti-cancer medicines.
You must talk to a doctor if you do not feel better or if you feel worse

Do not use Cytarabine Injection

• if you are allergic to cytarabine or any of the other ingredients of this
medicine (listed in section 6)
• if your blood cell count (number of cells in your blood) is very low due to
some cause other than cancer (unless your doctor decides the benefits of
treatment outweigh the risks)
• if you are feeling increasing difficulties in body coordination after radiation
treatment or treatment with another anticancer medicine such as methotrexate
• if you are pregnant
Tell your doctor if you think any of the above applies to you before this medicine
is used.

Warnings and precautions
Talk to your doctor or pharmacist before taking Cytarabine Injection.

Take special care with Cytarabine Injection

• if your blood cell count is low
• if you have any problems with your liver including jaundice (causes yellowing
of the skin)
• if you have recently received cancer medicine treatment or radiotherapy or
if you are due to have radiotherapy (the side effects of radiotherapy can be
made worse by cytarabine treatment)
• cytarabine strongly reduces blood cell production in the bone marrow and
your blood cell numbers can continue to fall for up to a week after stopping
treatment. Your doctor will test your blood regularly and examine your bone
marrow if required.
• if your bone marrow is still recovering from the effects of other medicines (your
doctor will only consider treatment with cytarabine if absolutely necessary)
• serious and sometimes life-threatening side effects can occur in the central
nervous system, the bowels, the lungs or the heart especially when treated
with high doses of cytarabine.
• the levels of uric acid (showing that the cancer cells are destroyed) in your
blood (hyperuricemia) may be high during treatment. Your doctor will tell you
if you need to take any medicine to control this.
• during treatment with cytarabine administration of certain vaccines is not advised.
If required, consult your doctor. Use of killed or inactivated vaccine may not have
the desired effect due to suppressed immune system while on cytarabine.
• during treatment with cytarabine granulocyte transfusion should be avoided
as severe respiratory insufficiency has been reported. If required, consult
your doctor.
Tell your doctor if any of the above applies to you before this medicine is used.
Your doctor will monitor your blood to check your blood cell count, your liver and
kidney functions and to monitor for raised uric acid levels.
Special care will be taken if cytarabine is to be given to a child. Cytarabine
should not be used in infants.

Other medicines and Cytarabine Injection
Tell your doctor, pharmacist or nurse if you are taking, have recently taken or
may take any other medicines as special care is needed if you are taking or
using other medicines as some could interact with cytarabine.
The effectiveness of the following medicines may be reduced or increased by
• methotrexate (a medicine used to treat a range of cancers and some
inflammatory conditions)
• digoxin or beta-acetyl digoxin tablets (heart medicine)
• gentamicin (an antibiotic)
• 5-fluorocytosine (a medicine used to treat fungal infections)
• medicines containing cyclophosphamide, vincristine and prednisone which
are used in cancer treatment programmes
• other medicines which decrease the activity of the immune system

Pregnancy, breast-feeding and fertility
If you are pregnant or breast-feeding, think you may be pregnant or are planning
to have a baby, ask your doctor or pharmacist for advice before taking this medicine
Avoid becoming pregnant while you or your partner is being treated with
cytarabine. As there is a risk of birth defects, women of childbearing potential
or their partner should use appropriate contraception methods during and up to
6 months after treatment with cytarabine to prevent pregnancy.
You should stop breast-feeding before starting treatment with cytarabine
because this medicine may be harmful to infants being breast-fed.
Ask your doctor or pharmacist for advice before taking any medicine.

lessen your ability to do so.

Injection will be diluted first.

Recommended Dose
Your doctor will work out the correct dose of cytarabine for you and how often it
must be given.
The dose will depend on your medical condition, your size and how well your liver
is working. Your doctor will tell how well your liver is working using blood tests.
You will have regular blood tests after your dose of cytarabine to check for side
effects. These tests may be done more often if you are elderly, as you may be
more likely to get side effects. Treatment may have to be stopped if your blood
cell count drops too low.
