About Vancomycin Dose Calculator

Converts a weight-based vancomycin dose and interval into the amount per administration and the total daily exposure per kilogram.

Formula

Weight-based interval dosing

Dose = weight x mg/kg; daily dose = dose x (24 / interval hours)

Worked example

With the default values below, Vancomycin Dose Calculator returns Dose per administration of 1,200. Change any input above and every figure here is recalculated in your browser.

Assumptions and limits

  • The result is derived only from the 3 inputs listed above. Anything not among them is not part of the calculation.
  • In particular, this calculator does not take inflation, tax, fees or charges or compounding frequency into account.
  • Figures are rounded for display to 1 decimal place, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.
  • Educational estimate only. Not a substitute for professional clinical judgement, and must not be used to make treatment or dosing decisions.
  • This is an estimate for general information and not professional medical advice. See the full disclaimer for the limits that apply to this kind of calculator.

How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.

Frequently Asked Questions

What monitoring is required?

Vancomycin needs therapeutic drug monitoring, now usually AUC-guided rather than trough-only.

Does renal function change the interval?

Yes. The interval lengthens as creatinine clearance falls, which is why the interval is an explicit input.
