Vancomycin AUC/MIC Target

AUC-based vancomycin dosing and monitoring.

Vancomycin AUC/MIC Target calculator

Result

1698mg/24h

Divide across dosing interval. Target AUC₂₄ 400 mg·h/L

CL = 4.2 L/h. Adjust at steady-state with Bayesian software (e.g., DoseMe, InsightRx).

200 to 800 mg·h/L

20 to 100 L

3 to 48 hours

How to use it

  1. 1

    AUC/MIC 400–600 mg·h/L target. ASHP 2020 guidance: AUC₂₄/MIC 400–600 for MRSA (assuming MIC = 1 mg/L).

  2. 2

    Estimate initial dose. CL vancomycin ≈ CrCl × 0.689. Dose ≈ AUC target × CL.

  3. 3

    Bayesian software preferred. DoseMe, InsightRx, or PrecisePK: two-level Bayesian monitoring gives most accurate AUC.

When to use it

MRSA bacteraemia and serious infections
ASHP guideline: AUC-guided dosing reduces nephrotoxicity vs. trough-only monitoring.
Trough monitoring no longer recommended
Trough 15–20 mg/L associated with nephrotoxicity without ensuring efficacy — abandoned in 2020 ASHP guideline.
Renal dose adjustment
eGFR drives half-life estimate; recalculate after eGFR change.
