Summary

Both agents can injure the kidney, and NSAID-related reductions in renal function may raise vancomycin levels, especially in neonates. This increases the risk of acute kidney injury.

What this interaction means in plain words

Ketorolac and Vancomycin can affect each other. The combination is often manageable, but it may need a change of dose, a change of timing, or extra checks while both are taken.

Ketorolac belongs to Musculoskeletal; Vancomycin belongs to Anti Bacterial.

Evidence level: Moderate

Why it happens

Additive nephrotoxicity, with NSAID inhibition of renal prostaglandins reducing glomerular filtration and vancomycin clearance.

What to do

Monitor serum creatinine and vancomycin trough or AUC levels, and avoid ketorolac in neonates and renally impaired patients. Use a non-NSAID analgesic where possible.

What to ask your pharmacist
