Other Comments


  • Prescriptions for this drug should be limited to the amount necessary for a single cycle of chemotherapy (i.e., a few days).
  • Cross-tolerance between this drug and delta-9-THC (marijuana) has been demonstrated in animal studies.
  • Overdosage: Activated charcoal is often more effective than emesis or lavage in decreasing absorption of drugs from the GI tract; consider charcoal instead of or in addition to gastric emptying and protect the patient's airway during this process. General supportive care and monitoring of vital signs is also recommended. The use of forced diuresis, peritoneal dialysis, hemodialysis, charcoal hemoperfusion, and cholestyramine has not been reported.
  • The estimated oral median lethal dose in female mice: between 1,000 to 2,000 mg/kg; in the female rat: greater than 2,000 mg/kg.
