Drug Dosage Calculator – Accurate Adult & Pediatric Medication Dosing
Accurate medication dosing is critical to patient safety and therapeutic effectiveness. Our AI-powered Drug Dosage Calculator provides healthcare professionals, pharmacists, nurses, and medical students with precise dosing calculations for adults and pediatric patients. Calculate weight-based dosing (mg/kg), adjust for renal function (GFR/CrCl), account for hepatic impairment, and identify maximum doses and contraindications. Free, instant, and no login required.
Calculate Drug Dosage NowComprehensive Medication Dosing for All Patient Populations
Calculate accurate drug doses instantly with our advanced dosing calculator that supports standard dosing, weight-based calculations, and special populations.
Adult Dosing
Standard recommended doses, dosing frequency, formulations (oral, IV, IM), and maximum daily doses.
Pediatric Dosing
Age-based dosing formulas, neonatal/infant/child calculations with weight-based mg/kg dosing and ceiling doses.
Renal Adjustment
GFR-based dose adjustment for kidney disease (CrCl >60, 30-60, <30 mL/min). Calculate safe doses in renal failure.
Hepatic Dosing
Hepatic impairment dosage adjustment for liver disease, cirrhosis, and hepatic dysfunction.
Contraindications
Identify key contraindications, precautions, and special populations requiring dose modification or avoidance.
Formulations
Multiple drug formulations (tablets, capsules, injections, suspensions) with available strengths and concentrations.
Safe, Accurate, Evidence-Based Drug Dosing
Prevent Medication Errors: Dosing errors are a leading cause of patient harm. Our calculator helps ensure precise calculations for every patient population.
Account for Renal & Hepatic Function: Standard dosing is unsafe in kidney or liver disease. Get adjusted doses based on actual renal function and hepatic status.
Pediatric-Specific Calculations: Children are not "small adults." Calculate age-appropriate and weight-based pediatric dosing with safety ceilings.
- 200+ medications with complete dosing data
- Weight-based calculations for precision dosing
- GFR-adjusted dosing for renal disease
- Hepatic adjustment for liver dysfunction
- Instant results with printable summaries
- Evidence-based clinical practice guidelines
- Free access for healthcare professionals
- Mobile-friendly for point-of-care use
