Indications and dosages
➣ Metastatic cancer of colon or rectum, given with 5-fluorouracil (5-FU) and leucovorin
Adults: On day 1, 85 mg/m2 oxaliplatin I.V. infusion and 200 mg/m2 leucovorin; give both drugs simultaneously over 2 hours, followed by 400 mg/m2 I.V. bolus of 5-FU over 2 to 4 minutes, then 600 mg/m2 5-FU I.V. as 22-hour continuous infusion. On day two, 200 mg/m2 leucovorin I.V. infusion over 2 hours, followed by 400 mg/m2 5-FU I.V. bolus over 2 to 4 minutes, then 600 mg/m2 5-FU I.V. as 22-hour continuous infusion.
• Hypersensitivity to drug or platinum products
Use cautiously in:
• radiation therapy
• recent pneumococcal or smallpox vaccination
• elderly patients
• pregnant or breastfeeding patients
☞ Follow facility policy for preparing, handling, and administering mutagenic, teratogenic, and carcinogenic drugs.
• Premedicate patient with antiemet-ics, as prescribed.
• Reconstitute with sterile water or dextrose 5% in water (D5W)-never with normal saline solution or other solutions containing chloride.
• Further dilute reconstituted drug in 250 to 500 ml of D5W.
• Infuse over 2 hours simultaneously with leucovorin, but in a separate I.V. bag.
• Don't use administration sets or needles that contain aluminum.
☞ Be aware of importance of using leucovorin rescue with this drug.
☞ Avoid extravasation, which may cause necrosis and other severe reactions.
• Know that treatment cycles are usually repeated every 2 weeks.

Other: weight loss, increased cold sensitivity, pain at injection site, anaphylaxis
Drug-drug. Aminoglycosides, loop diuretics: increased risk of nephrotoxicity
Aspirin, nonsteroidal anti-inflammatory drugs: increased risk of bleeding
Live-virus vaccines: decreased antibody response to vaccine
Myelosuppressants: increased bone marrow depression
Drug-diagnostic tests. Alanine aminotransferase, aspartate aminotransferase, bilirubin, creatinine: increased levels
Hemoglobin, neutrophils, platelets, white blood cells: decreased levels
Drug-behaviors. Alcohol use: increased risk of bleeding
☞ Monitor I.V. site frequently to avoid extravasation.
• Monitor CBC, blood chemistry, and kidney and liver function tests before each treatment cycle.
☞ Watch closely for blood dyscrasias, hemolytic uremic syndrome, serious pulmonary problems, and anaphylaxis.
• Conduct complete neurologic exam before and after each dose.
• Monitor vital signs and ECG. Evaluate cardiovascular and respiratory status closely.
• Assess patient's comfort level. Keep him warm during infusion to minimize neurologic effects.
• Watch for signs and symptoms of toxicity (paresthesia, nausea, vomiting).
• Inform patient that chemotherapy drugs can cause many adverse effects.
• Tell patient he'll receive drug from trained health care professionals in hospital setting.
☞ Instruct patient to inform nurse immediately if drug contacts his skin, eyes, or mouth.
• Advise patient to notify nurse if pain or redness occurs at I.V. site.
• Instruct patient to stay warm and avoid iced drinks to minimize neurologic symptoms.
☞ Tell patient to report itching, hives, swelling of hands or face, chest tightness, difficulty breathing, unsteadiness, severe diarrhea or vomiting, or tingling sensation in hands, arms, legs, or feet.
• As appropriate, review all other significant and life-threatening adverse reactions and interactions, especially those related to the drugs, tests, and behaviors mentioned above.
