Vancomycin Continuous Infusion Rate
Vancomycin continuous infusion arithmetic: loading dose and daily dose on actual body weight, the pump rate in mg/h and mL/h, each set against the 2020 consensus guideline ranges, and the bag concentration against the FDA label.

Example
- Actual body weight
- 70 kg
- Loading dose
- 20 mg/kg
- Daily dose
- 35 mg/kg/day
- Bag concentration
- 5 mg/mL
Result: Load 1,400 mg, then 102.1 mg/h (2,450 mg/day, 20.42 mL/h).
