Cytarabine is used in adults and children. The active ingredient is cytarabine.
Cytarabine is one of a group of medicines known as cytotoxics, these medicines are used in the
treatment of acute leukaemias (cancer of blood where you have too many white blood cells)
including prophylaxis and treatment of CNS involvement (meningeal leukaemia). Cytarabine
interferes with the growth of cancer cells, which are eventually destroyed.
Remission induction is an intensive treatment to force leukaemia into retreat. When it works,
the balance of cells in your blood becomes more normal and your health improves. This
relatively healthy period is called a remission.
Maintenance therapy is a milder treatment to make your remission last as long as possible.
Quite low doses of cytarabine are used to keep the leukaemia under control and stop it flaring
up again.



Do not use Cytarabine if you:
 are allergic (hypersensitive) to cytarabine, or any of the other ingredients of cytarabine.
 If the cell count in your blood report is very low due to some cause other than cancer, or as
decided by your doctor.
 If you are feeling increasing difficulties in body coordination after radiation treatment or
treatment with another anticancer drug such as methotrexate.
 if you are pregnant.

Take special care with Cytarabine Srides:
 if your bone marrow is in low state, therapy should be initiated under close medical
 if you have problem with your liver.
 Cytarabine strongly reduce blood cell production in the bone marrow. This can make you more
prone to infection or bleeding. The 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.
 Serious and sometimes life-threatening side effects can occur in the central nervous system, the
bowels or lungs.
 Your liver and kidney function should be monitored during cytarabine therapy. If your liver is
not working well before treatment, cytarabine should be given only under strict control.
 The levels of uric acid (showing that the cancer cells are destroyed) in your blood
(hyperuricaemia) 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 live or attenuated vaccine 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.
 Do not forget to tell you doctor if you have received radiotherapy.
Using 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.
 given medicines containing 5-Fluorocytosine (a medicine used to treat fungal infections).
 taking medicines containing digitoxin or beta-acetyldigoxin which are used to treat certain
heart conditions.
 taking Gentamicin (an antibiotic used to treat bacterial infections).
 given medicines containing cyclophosphamide, vincristine and prednisone which are used in
cancer treatment programmes.
Pregnancy, breast-feeding and fertility
Avoid becoming pregnant while you or your partner is being treated with cytarabine. If you are
sexually active, you are advised to use effective birth control to prevent pregnancy during treatment,
whether you are male or female. Cytarabine may cause birth defects, so it is important to tell your
doctor if you think you are pregnant. Men and women have to use effective contraception during
and up to 6 months after treatment.
You should stop breast-feeding before starting treatment with cytarabine because this medicine may
be harmful to infants being breast-fed.

Cytarabine may lead to suppression of menstrual cycles in females and lead to amenorrhea and may
suppress sperm production in male patients. Male patients undergoing cytarabine treatment should
use a reliable contraceptive method.
Ask your doctor or pharmacist for advice before taking any medicine.
Driving and using machinery
Cytarabine does not affect your ability to drive or use machinery. However, cancer treatment in
general can affect the ability of some patients to drive or operate machines. If you are affected, you
should not drive or use machines.
Important information about some of the ingredients of Cytarabine
Cytarabine 20mg/ml: 1ml solution contains 6,8 mg of sodium chloride equivalent to 2,67 mg/ml
To be taken into consideration by patients on a controlled sodium diet.
Method and route of administrations
Cytarabine will be given to you under the direction of specialists in hospital. Your doctor will
decide what dose to give and the number of days treatment you will receive depending on your
You may receive Cytarabine 20mg/ml either as an injection into a vein (intravenous), into a muscle
(intramuscular), into the space surrounding the spinal card (intrathecal) or under the skin
You may receive Cytarabine 100mg/ml as an injection into a vein (intravenous).
Based on your condition, your doctor will decide the dose of cytarabine, whether you are in
induction or maintenance therapy and your body surface area. Your body weight and height will be
used to calculate your body surface area.
During treatment you will need regular checks including blood tests. Your doctor will tell you how
often this should be done. He/she will be making regular checks of:
 Your blood, to check for low blood cell counts that may need treatment.
 Your liver – again using blood tests – to check that cytarabine is not affecting the way it
functions in a harmful way.
 Your kidneys – again using blood tests – to check that cytarabine is not affecting the way it
functions in a harmful way.
 Blood uric acid levels - cytarabine may increase uric acid levels in the blood. Another medicine
may be given if your uric acid levels are too high.
 If you are on dialysis, the doctor may alter the time of drug administration as dialysis may
decrease the effectiveness of the medicine.

If you receive high doses of Cytarabine:
High doses can worsen side effects like sores in the mouth or may decrease the number of white
blood cells and platelets (these help the blood to clot) in the blood. Should this happen, you may
need antibiotics or blood transfusions. Mouth ulcers can be treated to make them less uncomfortable
as they heal.
If you have any further questions on the use of this product, ask your doctor or pharmacist.


Like all medicines, Cytarabine injection can cause side effects, although not everybody gets them.
The side effects of cytarabine are dependent on the dose. The digestive tract is most commonly
affected, but also the blood.
Common: may affect up to 1 in 10 people

Cytarabine should for infusion be diluted with 0.9 % sodium chloride solution, or 5 % glucose

If Cytarabine comes in contact with skin, the exposed area should be rinsed with large amounts of
water and then thoroughly washed with soap and water. If the solution gets into the eyes, rinse very
carefully with large amounts of water, whereupon an eye specialist should be consulted
Pregnant staff should be excluded from working with this drug.
Cytotoxic Handling Guidelines
Should be administered by, or under the direct supervision of, a qualified physician who is
experienced in the use of cancer chemotherapeutic agents.
Preparation (Guidelines):
1. Chemotherapeutic agents should be prepared for administration only by professionals trained in
the safe use of the preparation.
2. Operations such as dilution and transfer to syringes should be carried out only in the designated
3. The personnel carrying out these procedures should be adequately protected with clothing,
gloves and eye shield.
4. Pregnant personnel are advised not to handle chemotherapeutic agents.
a) In the event of contact with the skin or eyes, the affected area should be washed with copious
amounts of water or normal saline. A bland cream may be used to treat the transient stinging of
skin. Medical advice should be sought if the eyes are affected.
b) In the event of spillage, operators should put on gloves and mop up the spilled material with a
sponge kept in the area for that purpose. Rinse the area twice with water. Put all solutions and
