Medication dosage calculator (weight-based)

Pediatric / weight-based dosing arithmetic only: dose = weight × mg/kg × frequency. Drug-specific max doses, age cut-offs, organ-function adjustments, and route-of-administration limits are NOT applied — always cross-check against an authoritative source (formulary, package insert) and the prescribing clinician's order.

⚠ Calculation aid only — not medical advice and not a substitute for a clinician's order. Verify against the formulary or package insert and the patient's individual factors before administering.
