Renal function

Please fill in all predictors to get an estimate of expected vancomycin exposure.


A table showing exposure predictions based on 15 mg/kg dosing for various dosing intervals will be generated below once all patient information is entered. For evaluation of custom regimens please use the inputs in this box.

Exposure predictions

* = exposure estimates at steady state. ** = Probabilities of AUC24 > 400 and Ctrough > 20 mg/L at steady state.

Serum creatinine

If serum creatinine is not available for the neonate patient, consider using typical levels given below (Jaffé assay), but apply dosing tool with caution. Checking a serum creatinine is recommended.

PMA (weeks) Typical creatinine
24 − 28 1.2 mg/dL
29 − 34 0.8 mg/dL
35 − 41 0.6 mg/dL
≥ 42 0.4 mg/dL

About NeoVanco

This web application was developed in collaboration between InsightRX and Adam Frymoyer, MD (Stanford University - Stanford Children's Health). It provides vancomycin starting dose advice for neonates based on a population pharmacokinetic model developed by Frymoyer A et al., described in AAC 2014 Nov; 58(11) with external validation described in Infect Dis Ther. 2015 Jun;4(2)

A description of the general tool framework can be found in Frymoyer A et al. J Pediatric Infect Dis Soc. 2017. Please contact for questions about the NeoVanco dosing tool.

This tool is intended for use in neonates with post-menstrual age <52 weeks, NO major congenital heart disease (other than VSD, ASD, PDA), and NO congenital kidney disease.

The dosing tool should not be used in patients on ECMO or renal replacement therapy. Caution is warranted in neonates with poor or worsening kidney function.
