Cancer cells take up floxuridine, which then slows or stops the growth of cancer cells in your body. The length of treatment depends on the types of drugs you are taking, how well your body responds to them, and the type of cancer you have.

# Other uses for this medicine
Floxuridine is also used to treat head, neck, brain, liver, gallbladder, and bile duct cancer. Floxuridine has been given by injection into a vein to treat solid tumors, acute leukemia in children, and cytomegalic inclusion disease in children with acute leukemia. Talk to your doctor about the possible risks of using this drug for your condition.
