What Cytarabine Injection is used for
Cytarabine belongs to a group of medicines known as antineoplastics. It is used to treat cancer.
How Cytarabine Injection works
Cytarabine works by preventing the growth of cancer cells and eventually destroying them. It is used alone or in combination with other medicines to treat some cancers, particularly cancers of the blood (especially leukaemia).
Cytarabine Injection may be used to treat other conditions that are not mentioned above. Your doctor will be able to tell you about the specific condition for which you have been prescribed Cytarabine Injection.
This medicine is available only with a doctor's prescription.
Use in Children
Cytarabine Injection is also used in children to treat blood cancers such as leukaemia. It is also sometimes used in combination with other medicines to treat non-Hodgkins lymphoma.

How Cytarabine Injection is given
Follow all directions given to you by your doctor or pharmacist carefully. They may differ from the information contained in this leaflet.
Cytarabine is given by a slow injection into a vein or under the skin. Occasionally it may be injected directly into the fluid around the spine. Cytarabine must only be given by a doctor or nurse.
Your doctor will decide what dose, how often and how long you will receive it. This depends on your condition and other factors, such as your weight, age, blood tests and whether or not other medicines are being given at the same time.
Cytarabine Injection may be given alone or in combination with other drugs.
If you are given too much (overdose)
Overdose is unlikely as Cytarabine Injection is given in hospital under the supervision of a doctor, or nurse trained to administer medicine intravenously. However, if you are given too much cytarabine, you may experience some of the effects listed under "Side effects" below.
Immediately telephone your doctor or the Poisons Information Centre (Phone Australia 13 11 26 or New Zealand 0800 POISON or 0800 764 766) for advice or go to Accident and Emergency at your nearest hospital if you think you may have been given too much cytarabine. Do this even if there are no signs of discomfort or poisoning.
Ask your doctor if you have any concerns. Your doctor has information on how to recognise and treat an overdose.
While you are given Cytarabine Injection
Things you must do
Cytarabine can temporarily lower the number of white blood cells in your blood, increasing the chance of you getting an infection. It can also lower the number of platelets, which are necessary for proper blood clotting. If this occurs there are certain precautions you can take, especially when your white cell and/or platelet cell count is low, to reduce the risk of infection or bleeding:
- if you can, avoid people with infections. Check with your doctor if you think you are getting an infection or if you get a fever or chills, cough or hoarseness, lower back or side pain, or painful or difficult urination
- check with your doctor immediately if you notice any unusual bleeding or bruising; black, tarry stools; blood in urine or stools; or pinpoint red spots on your skin
- be careful when using a regular toothbrush, dental floss or toothpick. Your doctor, dentist, or nurse may recommend other ways to clean your teeth and gums. Check with your medical doctor before having any dental work done
- do not touch your eyes or the inside of your nose unless you have just washed your hands and have not touched anything else in the meantime
- be careful not to cut yourself when you are using sharp objects such as a safety razor or fingernail or toenail cutters
- avoid contact sports or other situations where bruising or injury could occur.
If you are about to be started on any new medicine, remind your doctor and pharmacist that you are being given Cytarabine Injection.
Do not have any immunisations (vaccinations) without your doctor's approval. Cytarabine may lower your body's resistance and there is a chance you may get the infection the immunisation is meant to prevent.
Tell any other doctors, dentists, and pharmacists who treat you that you are being given this medicine.
If you are going to have surgery, tell the surgeon or anaesthetist that you are being given this medicine. It may affect other medicines used during surgery.
If you fall pregnant while receiving this medicine, tell your doctor immediately.
If you are about to have any blood tests, tell your doctor that you are receiving this medicine. It may interfere with the results of certain tests.
Keep all of your doctor's appointments so that your progress can be checked.
Your doctor may do certain tests from time to time to make sure the medicine is working and to prevent unwanted side effects.
Things to be careful of
Be careful driving or operating machinery until you know how Cytarabine Injection affects you. You may feel tired and weaker while you are receiving a course of cytarabine therapy.
While you are receiving this medicine, your doctor may want you to drink extra fluids so you will pass more urine. This will help prevent kidney problems and keep your kidneys working well.
Tell your doctor, nurse or pharmacist as soon as possible if you do not feel well while you are being given Cytarabine Injection. Like other medicines, cytarabine can cause some side effects. Some of these side effects may be prevented or treated with other medicines. If side effects do occur, their severity usually depends on the dose of cytarabine you receive. Some may be serious and need medical attention.
It can be difficult to tell whether side effects are the result of having Cytarabine Injection, effects of your condition or side effects of other medicines you may be taking. For this reason it is important to tell your doctor of any change in your condition.
Ask your doctor, nurse or pharmacist to answer any questions that you may have. Do not be alarmed by this list of possible side effects. You may not experience any of them.

- hair loss, especially of the scalp

- muscle or bone pain
- swelling and redness along a vein which is extremely tender when touched

Tell your doctor or pharmacist if you notice anything else that is making you feel unwell. Other side effects not listed above may also occur in some people.
