Floxuridine

Floxuridine is used to treat cancer of gastrointestinal (GI) tract (cancer of the stomach or intestines) that has spread to the liver. Floxuridine is in a class of medications called antimetabolites. It works by slowing or stopping the growth of cancer cells in your body.

Floxuridine comes as a powder to be mixed with liquid to be continuously injected intra-arterially (into an artery) that supplies blood to the tumor.

This medication may be prescribed for other uses; ask your doctor or pharmacist for more information.

Before receiving floxuridine,

• tell your doctor and pharmacist if you are allergic to floxuridine, fluorouracil, any other medications, or any of the ingredients in floxuridine injection. Ask your pharmacist for a list of the ingredients.

• tell your doctor and pharmacist what other prescription and nonprescription medications, vitamins, nutritional supplements, and herbal products you are taking or plan to take. Be sure to mention any of the following: medications that suppress the immune system such as azathioprine (Imuran), cyclosporine (Neoral, Sandimmune), methotrexate (Rheumatrex), sirolimus (Rapamune), and tacrolimus (Prograf). Your doctor may need to monitor you carefully for side effects. Many other medications may also interact with floxuridine, so be sure to tell your doctor about all the medications you are taking, even those that do not appear on this list.

• tell your doctor if you have an infection or are not able to eat enough or a good balance of food. Your doctor may not want you to receive floxuridine injection.

• tell your doctor if you have previously received radiation (x-ray) therapy or treatment with other chemotherapy medications or if you have or have ever had kidney or liver disease.
