Cytarabine (sye-TARE-a-been) belongs to the group of medicines called antimetabolites. It is used to treat some kinds of cancers of the blood. It may also be used to treat other kinds of cancer, as determined by your doctor.
Cytarabine interferes with the growth of cancer cells, which are eventually destroyed. Since the growth of normal body cells may also be affected by cytarabine, other effects will also occur. Some of these may be serious and must be reported to your doctor. Other effects, like hair loss, may not be serious but may cause concern. Some effects may not occur for months or years after the medicine is used.
Before you begin treatment with cytarabine, you and your doctor should talk about the good this medicine will do as well as the risks of using it.
Cytarabine is to be administered only by or under the immediate supervision of your doctor. It is available in the following dosage form:
In deciding to use a medicine, the risks of taking the medicine must be weighed against the good it will do. This is a decision you and your doctor will make. For cytarabine, the following should be considered:
Allergies--Tell your doctor if you have ever had any unusual or allergic reaction to cytarabine.
Pregnancy--This medicine may cause birth defects (such as defects of the arms, legs, or ears, which occurred in two babies) if either the male or female is taking it at the time of conception or if it is taken during pregnancy. In addition, many cancer medicines may cause sterility. Although sterility has been reported with this medicine, it is usually only temporary.
Be sure that you have discussed this with your doctor before taking this medicine. It is best to use some kind of birth control while you are receiving cytarabine. Tell your doctor right away if you think you have become pregnant while receiving cytarabine.
Breast-feeding--Because cytarabine may cause serious side effects, breast-feeding is generally not recommended while you are receiving it.
Children--Although there is no specific information comparing use of cytarabine in children with use in other age groups, this medicine is not expected to cause different side effects or problems in children than it does in adults.
Older adults--Many medicines have not been studied specifically in older people. Therefore, it may not be known whether they work exactly the same way they do in younger adults. Although there is no specific information comparing use of cytarabine in the elderly with use in other age groups, this medicine is not expected to cause different side effects or problems in older people than it does in younger adults.
Other medicines--Although certain medicines should not be used together at all, in other cases two different medicines may be used together even if an interaction might occur. In these cases, your doctor may want to change the dose, or other precautions may be necessary. When you are receiving cytarabine, it is especially important that your health care professional know if you are taking any of the following:
Other medical problems--The presence of other medical problems may affect the use of cytarabine. Make sure you tell your doctor if you have any other medical problems, especially:
This medicine is sometimes given together with certain other medicines. If you are using a combination of medicines, it is important that you receive each one at the proper time. If you are taking some of these medicines by mouth, ask your health care professional to help you plan a way to take them at the right times.
While you are receiving this medicine, your doctor may want you to drink extra fluids so that you will pass more urine. This will help prevent kidney problems and keep your kidneys working well.
This medicine often causes nausea and vomiting. However, it is very important that you continue to receive the medicine even if you begin to feel ill. Ask your health care professional for ways to lessen these effects.
Dosing--The dose of cytarabine will be different for
different patients. The dose that is used may depend on a number of things,
including what the medicine is being used for, the patient's weight, and whether
or not other medicines are also being taken.
If you are
receiving cytarabine at home, follow your doctor's orders or the directions
on the label
. If you have any questions about the proper dose of cytarabine,
ask your doctor. It is very important that your doctor check your progress at regular visits
to make sure that this medicine is working properly and to check for
unwanted effects. While you are being treated with cytarabine, and after you stop treatment
with it,
do not have any immunizations (vaccinations)
without your doctor's approval
. Cytarabine may lower your body's resistance
and there is a chance you might get the infection the immunization is meant
to prevent. In addition, other persons living in your household should not
take oral polio vaccine since there is a chance they could pass the polio
virus on to you. Also, avoid persons who have taken oral polio vaccine. Do
not get close to them and do not stay in the same room with them for very
long. If you cannot take these precautions, you should consider wearing a
protective face mask that covers the nose and mouth. Cytarabine can temporarily lower the number of white blood cells in your
blood, increasing the chance of 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 blood
count is low, to reduce the risk of infection or bleeding:
