Details on dosage

Adult dose for liver metastasis of adenocarcinoma
The recommended dose is 0.1–0.6 mg/kg/day via continuous arterial infusion. Higher dosages (0.4–0.6 mg) should be used in hepatic artery insertions because the liver will metabolize the drug, reducing systemic toxicity.
The therapy can be continued until the adverse reactions are evident. After these side effects subside, the therapy can be resumed.
The patient should continue to receive floxuridine as long as the response continues.
Use: To provide palliative care for gastrointestinal adenocarcinoma that has metastatic spread to the liver. This is done by giving a continuous intra-arterial regional infusion.

What happens if I miss the dose?

You are unlikely to miss a dosage because you will be receiving floxuridine in a clinical environment.

What happens if I overdose?
