Cytarabine (DepoCyt®, Cytosar-U®)

Cytarabine

Brand Names: DepoCyt®, Cytosar-U®

Cytarabine is used in the treatment of certain types of leukemia. This drug is also known as Ara-C and cytosine arabinoside.

Cytarabine is in a class of drugs known as antimetabolites. These drugs are similar in structure to normal substances inside cells, which means that cells will readily incorporate these drugs inside. However, once the medicine is incorporated, the cell is unable to divide. There are many types of antimetabolites, categorized according to the substance with which they interact. Cytarabine is a pyrimidine antagonist.

This medication is given as infusion into a vein (intravenous), into a muscle (intramuscular), or directly into the spinal fluid (intraventricular or intrathecal infusion). The exact dose, schedule, and route of administration depends on the type of cancer being treated, how well the cancer is responding to the drug, height, weight, general health, and several other factors. Your doctor will determine the approach that is best for you

Cytarabine side effects

To prevent problematic interactions between cytarabine and other drugs, be sure to tell your doctor if you are allergic to any medications, and what other medications and supplements you are currently taking. You should also inform your doctor if you have or ever had liver tumor, liver disease, kidney disease, are pregnant, planning to become pregnant, or are breastfeeding. During treatment with cytarabine, you should not receive any vaccinations without first speaking with your doctor.
