Warnings/Precautions |
|
The U.S. Food and Drug Administration (FDA) currently recommends that
procedures for proper handling and disposal of antineoplastic agents be
considered.
Use with caution in patients who have had high-dose pelvic radiation or
previous use of alkylating agents. Patient should be hospitalized during initial
course of therapy.
Use of floxuridine with pentostatin has been associated with a high incidence
of fatal pulmonary toxicity; this combination is not recommended.
Floxuridine preparation should be performed in a Class II laminar flow
biologic safety cabinet. Personnel should be wearing surgical gloves and a
closed front surgical gown with knit cuffs. Appropriate safety equipment is
recommended for preparation, administration, and disposal of antineoplastics. If
floxuridine contacts the skin, wash and flush thoroughly with water.

Mechanism of action and pharmacokinetics are very similar to 5-FU;
FUDR® is the deoxyribonucleotide of 5-FU. Inhibits DNA and
RNA synthesis via formation of carbonium ions; cross-links strands of DNA,
causing an imbalance of growth and cell death |

Information |
|
This drug can only be administered by infusion. Follow instructions of
prescriber for care of implantable pump. During therapy, do not use alcohol,
aspirin-containing products, and OTC medications without consulting prescriber.
It is important to maintain adequate nutrition and hydration (2-3 L/day of
fluids unless instructed to restrict fluid intake) during therapy; frequent
small meals may help. You may experience mild nausea or vomiting (frequent small
meals, frequent mouth care, sucking lozenges, or chewing gum may help); you may
experience loss of hair (reversible); you will be more susceptible to infection
(avoid crowds and exposure to infection as much as possible). Yogurt or
buttermilk may help reduce diarrhea. Frequent mouth care and use of a soft
toothbrush or cotton swabs may help prevent mouth sores. This drug may cause
sterility or birth defects. Increased emotional or physical stress will
adversely affect the response to this medication. Notify prescriber if you are
experiencing unusual or elevated levels of stress. Report extreme fatigue, pain
or numbness in extremities, severe GI upset or diarrhea, bleeding or bruising,
fever, chills, sore throat, vaginal discharge, or signs of fluid retention (eg,
swelling extremities, difficulty breathing, unusual weight gain).
