Only a doctor with training in administering chemotherapy drugs for cancer should administer floxuridine injection. The initial dosage of your drug will be administered in a hospital. Your doctor will keep a close eye on you both during and after the drug has been administered.

Why is this medication prescribed?

Treatment for gastrointestinal (GI) tract cancer (cancer of the stomach or intestines) that has metastasized to the liver involves the drug floxuridine. The drug floxuridine belongs to the group of drugs known as antimetabolites. It functions by reducing or halting the development of cancer cells within your body.

How should this medicine be used?

The drug floxuridine is available as a powder to be dissolved in a liquid and continually injected intra-arterially (into an artery supplying the tumor with blood).

Other uses for this medicine

Ask your doctor or pharmacist for more details if you believe this drug should be used for something else.

What special precautions should I follow?

Before receiving floxuridine,

  • If you have an allergy to any of the substances in floxuridine injection, including fluorouracil, tell your doctor and pharmacist. Request a list of the components from your pharmacist.
  • Inform your doctor and pharmacist about any additional prescription and over-the-counter drugs, vitamins, dietary supplements, and herbal products you are now taking or intend to use. Incorporate any of the following: such as tacrolimus (Prograf), azathioprine (Imuran), cyclosporine (Neoral), methotrexate (Rheumatrex), sirolimus (Rapamune), and cyclosporine (Neoral, Sandimmune). Your doctor may need to keep a close eye out for any negative effects. Tell your doctor about all of the medications you are taking, even any not on this list, since many other drugs may also interact with floxuridine.
  • If you have an infection or are unable to consume an adequate amount of food that is balanced, let your doctor know. The injection of floxuridine might not be recommended by your doctor.
  • Inform your doctor if you have or have ever had kidney or liver illness, undergone radiation (x-ray) therapy, or have gotten treatment with any other chemotherapy drugs.
  • Inform your doctor if you are expecting, intend to get pregnant, or are nursing a baby. While having a floxuridine injection, you shouldn’t get pregnant or breastfeed. Call your doctor if you conceive while receiving an injection of floxuridine. The fetus could suffer from floxuridine.
