What is the target AUC/MIC for vancomycin in MRSA infections?

Current ASHP/IDSA/SIDP 2020 guidelines recommend an AUC/MIC target of 400-600 mg·h/L for serious MRSA infections with MIC ≤1 μg/mL; trough-only monitoring is no longer recommended.

How is the Cockcroft-Gault equation used for vancomycin?

CrCl (mL/min) = [(140-age) × actual body weight] / (72 × SCr) × 0.85 (females); use actual body weight unless patient is >20% above IBW, then use adjusted BW = IBW + 0.4(ABW-IBW).

What initial vancomycin dose is recommended?

Loading dose 25 mg/kg (max 3g) for critically ill patients; maintenance 15-20 mg/kg every 8-12h (adjusted to CrCl); infuse at ≤10 mg/min to avoid red man syndrome.

What nephrotoxicity monitoring is required for vancomycin?

Serum creatinine every 48-72h; AUC ≥650 significantly increases nephrotoxicity risk; concomitant piperacillin-tazobactam doubles nephrotoxicity rate vs cefepime and should be avoided when possible.

When should vancomycin dose be adjusted in renal failure?

For CrCl <30 mL/min or ESRD, loading dose unchanged but maintenance interval extended; AUC monitoring via Bayesian tools is especially important in renally impaired patients.

Vancomycin Dosing Calculator (Cockcroft-Gault AUC/MIC Method)

Calculates vancomycin dosing using AUC/MIC target attainment methodology per 2020 ASHP/IDSA/SIDP consensus guidelines, integrating Cockcroft-Gault CrCl, patient weight, and target AUC 400-600 mg·h/L.
