Both calculators run independently — change the inputs on either side to compare results.

Medication Dosage Calculator

Compute a renal-function-adjusted medication dosage using patient weight, the prescribed mg/kg dose, and Cockcroft-Gault creatinine clearance scaled to a reference of 120 mL/min. Provides a rough dose estimate, not a substitute for clinical pharmacy review.

Kidney Function Calculator (eGFR)

Estimates your glomerular filtration rate (eGFR) using the CKD-EPI equation from serum creatinine, age, sex, and race. Clinicians and patients use it to stage chronic kidney disease and track how well the kidneys are filtering blood.
