Vancomycin AUC24 (Equation-Based Estimate)
Simplified PK estimate of AUC24 and AUC24/MIC.
What is Vancomycin AUC24 (Equation-Based Estimate)?
Simplified PK estimate of AUC24 and AUC24/MIC. Vancomycin AUC24 is intended for use in: Adults.
How to Use the Vancomycin AUC24 Calculator
- Enter Weight in kg.
- Enter Creatinine clearance (CrCl) in mL/min.
- Enter Total daily dose in mg/day.
- Enter MIC (optional) in mg/L. Defaults to 1 mg/L if left blank
- Click Calculate to see your result and interpretation.
Formula & Version
This calculator uses formula version 1.0, last reviewed September 2026.
Clinical Considerations & Limitations
- This is a population-average, equation-based approximation only — the guideline-preferred method uses two measured levels and Bayesian software for an individualized AUC estimate.
- The clearance/volume-of-distribution population coefficients used here should be independently verified against the primary source before clinical use.
- Target AUC24/MIC is generally 400-600 for serious MRSA infections — values above this range raise nephrotoxicity risk.

What are the limitations of Vancomycin AUC24?
This is a population-average, equation-based approximation only — the guideline-preferred method uses two measured levels and Bayesian software for an individualized AUC estimate. The clearance/volume-of-distribution population coefficients used here should be independently verified against the primary source before clinical use. Target AUC24/MIC is generally 400-600 for serious MRSA infections — values above this range raise nephrotoxicity risk.

Is Vancomycin AUC24 a diagnosis?
No. Vancomycin AUC24 produces a score or estimate to support clinical decision-making — it is not a diagnosis and should be interpreted alongside full clinical judgement.
