Weight-Based Dosing
Many medications, especially for children and in hospital settings, are dosed based on body weight (mg/kg). This ensures appropriate dosing across different patient sizes. Common examples include antibiotics, chemotherapy, and pediatric medications.
How to Use This Calculator
Enter the patient's weight and the prescribed dose in mg/kg. The calculator provides the dose in mg and converts to liquid volume for common concentrations. Always verify calculations before administering medication. Check maximum doses - some drugs have weight-based dosing up to a maximum.
CRITICAL Safety Notes
This calculator is for educational purposes only. Always verify calculations independently. Use clinical judgment and consult prescribing information. Check for maximum doses. Renal and hepatic function may require dose adjustment. Pediatric dosing requires extra caution. When in doubt, consult a pharmacist or physician.
