Renal Dose Adjustment Calculator for 25+ Drugs

Adjusts doses for 25+ commonly renally cleared medications including carbapenems, beta-lactams, antivirals (acyclovir, valacyclovir), gabapentin, pregabalin, and allopurinol based on CrCl using Cockcroft-Gault equation.

Clinical Guidance

BMI is a screening measure of body size, not a direct measure of body fat. The standard WHO categories are underweight (<18.5), normal (18.5–24.9), overweight (25–29.9), and obese (≥30).

BMI can overestimate body fat in athletes with high muscle mass and underestimate it in older adults with low muscle mass. Interpret it alongside waist circumference and clinical context rather than as a standalone diagnosis.

How It Works

Adjusts doses for 25+ commonly renally cleared medications including carbapenems, beta-lactams, antivirals (acyclovir, valacyclovir), gabapentin, pregabalin, and allopurinol based on CrCl using Cockcroft-Gault equation

Each component has a specific meaning:

  • CrCl — The crcl recorded for the scenario being assessed.

Note: Interpret the renal drug dosing result against the thresholds and context described above.

How to Use

Enter the CrCl for the scenario you are assessing. Adjusts doses for 25+ commonly renally cleared medications including carbapenems, beta-lactams, antivirals (acyclovir, valacyclovir), gabapentin, pregabalin, and allopurinol based on CrCl using Cockcroft-Gault equation. Use the renal drug dosing result to inform your calculation.
