Drug Interaction Report

MONITOR: Theoretically, coadministration with drugs that are nephrotoxic may delay and/or decrease the clearance of oxaliplatin, which is primarily eliminated unchanged by the kidney. However, formal studies have not been conducted.

MANAGEMENT: Caution is advised if oxaliplatin is used in patients who have recently received or are receiving treatment with potentially nephrotoxic drugs (e.g., aminoglycosides; polypeptide, glycopeptide, and polymyxin antibiotics; amphotericin B; adefovir; cidofovir; tenofovir; foscarnet; cisplatin; deferasirox; gallium nitrate; lithium; mesalamine; certain immunosuppressants; intravenous bisphosphonates; intravenous pentamidine; high intravenous dosages of methotrexate; high dosages and/or chronic use of nonsteroidal anti-inflammatory agents). The potential for increased toxicity of oxaliplatin such as peripheral sensory neuropathies and neutropenia should be considered. Renal function should be closely monitored during therapy.
