Medicine
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.

Medicine
BSA-Based Dosage Calculator
Compute a body-surface-area-based medication dose using the DuBois BSA formula multiplied by the per-m² dose. Standard approach for chemotherapy and a few other classes of drugs whose pharmacokinetics scale with BSA.
