The maximum dose of oxaliplatin that has been administered in a single infusion is 825 mg. Several cases of overdoses have been reported with oxaliplatin. Adverse reactions observed following an overdosage were grade 4 thrombocytopenia (less than 25,000/mm3) without bleeding, anemia, sensory neuropathy (including paresthesia, dysesthesia, laryngospasm, and facial muscle spasms), gastrointestinal disorders (including nausea, vomiting, stomatitis, flatulence, abdomen enlarged and grade 4 intestinal obstruction), grade 4 dehydration, dyspnea, wheezing, chest pain, respiratory failure, severe bradycardia, and death. Closely monitor patients suspected of receiving an overdose, including for the adverse reactions described above, and administer appropriate supportive treatment.^L47206

Based on its direct interaction with DNA, ELOXATIN can cause fetal harm when administered to a pregnant woman. The available human data do not establish the presence or absence of major birth defects or miscarriages related to the use of oxaliplatin. Reproductive toxicity studies demonstrated adverse effects on embryo-fetal development in rats at maternal doses that were below the recommended human dose based on body surface area. Advise a pregnant woman of the potential risk to a fetus.^L47206

In the adjuvant treatment trial, 400 patients who received oxaliplatin with fluorouracil/leucovorin were greater than or equal to 65 years. The effect of oxaliplatin in patients greater than or equal to 65 years was not conclusive. Patients greater than or equal to 65 years receiving ELOXATIN experienced more diarrhea and grade 3-4 neutropenia (45% vs 39%) compared to patients less than 65 years.^L47206

The AUC of unbound platinum in plasma ultrafiltrate was increased in patients with renal impairment. No dose reduction is recommended for patients with mild (creatinine clearance 50 to 79 mL/min) or moderate (creatinine clearance 30 to 49 mL/min) renal impairment, calculated by Cockcroft-Gault equation. Reduce the dose of oxaliplatin in patients with severe renal impairment (creatinine clearance less than 30 mL/min).^L47206

Long-term animal studies have not been performed to evaluate the carcinogenic potential of oxaliplatin. Oxaliplatin was not mutagenic to bacteria (Ames test) but was mutagenic to mammalian cells in vitro (L5178Y mouse lymphoma assay). Oxaliplatin was clastogenic both in vitro (chromosome aberration in human lymphocytes) and in vivo (mouse bone marrow micronucleus assay).^L47206

In a fertility study, male rats were given oxaliplatin at 0, 0.5, 1, or 2 mg/kg/day for five days every 21 days for a total of three cycles prior to mating with females that received two cycles of oxaliplatin on the same schedule. A dose of 2 mg/kg/day (less than one-seventh the recommended human dose on a body surface area basis) did not affect the pregnancy rate but resulted in 97% postimplantation loss (increased early resorptions, decreased live fetuses, decreased live births), and delayed growth (decreased fetal weight).^L47206

Testicular damage, characterized by degeneration, hypoplasia, and atrophy, was observed in dogs administered oxaliplatin at 0.75 mg/kg/day (approximately one-sixth of the recommended human dose on a body surface area basis) × 5 days every 28 days for three cycles. A no-effect level was not identified.^L47206
