How to Use This Calculator
- Enter the patient's weight in kilograms (kg)
- Enter the drug concentration in milligrams per milliliter (mg/mL)
- Enter the prescribed dose in milligrams per kilogram (mg/kg)
- Click the "Calculate" button to compute the dosage
Understanding the Results
The calculator provides three key results:
- Total Dose: The total amount of medication required in milligrams (mg)
- Required Volume: The volume of medication needed in milliliters (mL)
- Dosage Rate: The recommended infusion rate in milliliters per hour (mL/hour)
Working Principle
This calculator uses the formula:
Total Dose (mg) = Patient Weight (kg) × Prescribed Dose (mg/kg)
Required Volume (mL) = Total Dose (mg) ÷ Drug Concentration (mg/mL)
The dosage rate is typically set to infuse the medication over a period of one hour, but clinical judgment should always be used when setting infusion rates.
Important Notes
- This calculator provides general guidance only and should not be used as the sole basis for clinical decision-making
- Always verify calculations with institutional guidelines and consult with a healthcare professional before administering medications
