Safety

Monitoring parameters

Interactions

Contraindicated — 1

Gentamicin (Systemic)

contraindicated

Both are directly nephrotoxic via different mechanisms (cisplatin: proximal tubular DNA damage; gentamicin: proximal tubular lysosomal accumulation). Combined risk of irreversible renal failure.

Management: NEVER combine. Allow renal recovery (minimum 2 weeks, confirm BUN/creatinine normalized) between agents.

Major — 2

Furosemide

major

Furosemide increases cisplatin nephrotoxicity by concentrating cisplatin in renal tubules and reducing renal blood flow. Contrast: saline diuresis is protective.

Management: Do NOT use furosemide with cisplatin. Use aggressive saline diuresis (NaCl 0.9%) before, during, and after cisplatin infusion instead.

Meloxicam

major

NSAID reduces renal prostaglandin-mediated blood flow + cisplatin direct nephrotoxicity: synergistic renal injury.

Management: Avoid NSAIDs during cisplatin cycles. If pain management needed, use opioids.

Moderate — 1

Gemcitabine

moderate

Gemcitabine increases cisplatin intracellular accumulation (synergistic antitumor effect). However, also increased nephrotoxicity when cisplatin given before gemcitabine.

Management: If combined, give gemcitabine BEFORE cisplatin (reduces nephrotoxicity). Ensure aggressive hydration.

Carboplatin

Alkylating-like platinum complex that forms intrastrand and interstrand DNA crosslinks, preventing DNA replication and transcription. Less nephrotoxic than cisplatin but more myelosuppressive. Safe for use in cats.
