Dosage Calculator – Accurate & User-Friendly Tool

This tool helps you calculate the correct medication dosage based on given parameters.

Dosage Calculator

This dosage calculator helps you estimate the total dosage required for a patient over a specific time period. Fill in the dosage per kg, the patient’s weight, dosage frequency per day, and the duration of the treatment.

How to Use:

  • Enter the dosage per kg (in mg/kg).
  • Input the patient’s weight in kilograms (kg).
  • Specify how many times per day the dosage is administered.
  • Enter the duration of the treatment in days.
  • Click the “Calculate” button to get the total dosage required for the treatment period.

Calculation Explanation:

The calculator multiplies the dosage per kg by the patient’s weight to get the single dose. This single dose is then multiplied by the frequency per day to get the daily dose. Finally, the daily dose is multiplied by the number of days to get the total dosage required:

Total Dosage = Dosage per kg x Weight x Frequency per day x Duration


This calculator is a basic tool and does not substitute professional medical advice. It assumes constant dosage per kilogram without considerations for maximum dosage limits, divided doses, individual patient variation or specific medical conditions. Always consult with a healthcare provider for accurate dosage and treatment plans.

Use Cases for This Calculator

Calculate medication dosage based on weight

Enter the patient’s weight and the prescribed dosage per kilogram. The calculator instantly provides the correct dosage based on the weight input. Ensure to double-check the results before administering the medication.

Determine the total volume for liquid medication

Input the dosage concentration and the prescribed dosage. The calculator will display the total volume of liquid medication needed for the prescribed dosage. This feature streamlines the process of preparing liquid medications accurately.

Convert between different measurement units

You have the flexibility to convert between units such as milligrams, micrograms, or international units. Simply input the value and select the desired unit for conversion. The calculator will instantly convert the dosage to the selected unit for convenience.

Adjust dosage based on medication concentration

By entering the current medication concentration and the prescribed dosage, you can accurately determine the adjusted dosage needed. This functionality is crucial for ensuring precise administration when dealing with medications of varying strengths.

Calculate dosage frequency

Input the total daily dosage and the number of doses required per day. The calculator will automatically determine the dosage frequency for the prescribed medication. This helps in organizing the dosage schedule efficiently.

Verify pediatric medication dosages

For pediatric patients, input the child’s weight and age along with the prescribed dosage. The calculator will generate the correct dosage based on the weight and age factors. Always consult healthcare professionals for pediatric medication dosages.

Calculate infusion rates for IV medications

Enter the total volume of medication, the infusion time, and the prescribed infusion rate. The calculator will compute the exact infusion rate required for the IV medication. This ensures accurate and safe administration of IV medications.

Determine dosage adjustments for renal impairment

Input the patient’s creatinine clearance level and the usual dosage. The calculator will provide the adjusted dosage based on the renal function. This feature is essential for tailoring medication dosages to avoid complications in patients with renal impairment.

Calculate medication titration for gradual dosage adjustments

Input the starting dosage, target dosage, and the duration for titration. The calculator will determine the incremental dosage adjustments needed over the specified duration. This simplifies the process of gradually adjusting medication dosages for optimal therapeutic outcomes.

Check medication compatibility for co-administration

Input multiple medications and check for possible drug interactions or compatibility issues. The calculator will analyze the compatibility of the entered medications and provide insights into safe co-administration. Always consult healthcare providers for detailed information on medication interactions.
