How to 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 (telephone 13
11 26) for advice, or go to Accident and Emergency at the nearest hospital, if you
think that you or anyone else 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, or your partner, become 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.
