The possibility of overdosage with floxuridine is unlikely in view of the mode of administration. Nevertheless, the anticipated manifestations would be nausea, vomiting, diarrhea, gastrointestinal ulceration and bleeding, bone marrow depression (including thrombocytopenia, leukopenia and agranulocytosis). No specific antidotal therapy exists. Patients who have been exposed to an overdosage of floxuridine should be monitored hematologically for at least 4 weeks. Should abnormalities appear, appropriate therapy should be utilized.
The acute intravenous toxicity of floxuridine is as follows:
(mg/kg ± S.E.)
|Mouse||880 ± 51|
|Rat||670 ± 73|
|Rabbit||94 ± 19.6|
|Dog||157 ± 46|
Floxuridine therapy is contraindicated for patients in a poor nutritional state, those with depressed bone marrow function or those with potentially serious infections.
