How should I use floxuridine?

You may receive your first dose in a hospital or clinic setting to quickly treat any serious side effects.

Floxuridine is injected into an artery through an infusion pump. A healthcare provider will give you this injection.

You will be watched closely while receiving floxuridine, to make sure you do not have a severe reaction.

Floxuridine can increase your risk of bleeding or infection. You will need frequent medical tests. Your cancer treatments may be delayed based on the results.

What happens if I miss a dose?

Because you will receive floxuridine in a clinical setting, you are not likely to miss a dose.

What happens if I overdose?

Since this medication is given by a healthcare professional in a medical setting, an overdose is unlikely to occur.

What should I avoid while using floxuridine?

Avoid being near people who are sick or have infections. Tell your doctor at once if you develop signs of infection.

Do not receive a "live" vaccine while using floxuridine, and avoid coming into contact with anyone who has recently received a live vaccine. There is a chance that the virus could be passed on to you. Live vaccines include measles, mumps, rubella (MMR), rotavirus, typhoid, yellow fever, varicella (chickenpox), zoster (shingles), and nasal flu (influenza) vaccine.

Floxuridine dosing information

Usual Adult Dose for Liver Metastasis in Adenocarcinoma:

Recommended dose: 0.1 to 0.6 mg/kg/day by continuous arterial infusion; the higher dosage ranges (0.4 mg to 0.6 mg) are usually used for hepatic artery infusion because the liver metabolizes the drug (thus reducing the potential for systemic toxicity)

-Therapy can be given until adverse reactions appear. When these side effects have subsided, therapy may be resumed.
-The patient should be maintained on therapy as long as response to floxuridine continues.

Use: For the palliative management of gastrointestinal adenocarcinoma metastatic to the liver, when given by continuous regional intra-arterial infusion in carefully selected patients who are considered incurable by surgery or other means.

What other drugs will affect floxuridine?

Other drugs may affect floxuridine, including prescription and over-the-counter medicines, vitamins, and herbal products. Tell your doctor about all your current medicines and any medicine you start or stop using.
