Medication Dosage Calculator (Weight-Based)
Medication Dosage Calculator (Weight-Based) is evaluated from Patient Weight, Dose per kg and Doses per Day. The calculation reports Calculated Single Dose, Calculated Total Daily Dose and Single Dose.

About the Medication Dosage Calculator (Weight-Based)
The calculator uses a multi formula configuration. Each reported value is read as a direct evaluation of the stored rules with the declared field formats and units.
Formula basis:
Single Dose = Dose (mg/kg) x Weight (kg)
Daily Dose = Single Dose x Doses per Day
Capped Dose = min(calculated dose, maximum safe dose)
Interpret the outputs in the order shown by the result fields. Optional inputs affect only the outputs that depend on those variables.
Formula & How It Works
The calculation applies the following relations exactly as recorded in the metadata: Single Dose = Dose (mg/kg) x Weight (kg) Daily Dose = Single Dose x Doses per Day Capped Dose = min(calculated dose, maximum safe dose) Each output field is produced by substituting the supplied inputs into the relevant relation and then applying the declared rounding or text format.
Worked Examples
Example 1: Pediatric Amoxicillin — 25 kg Child, Ear Infection
Inputs
With Patient Weight = 25, Dose per kg = 45, Doses per Day = 2 and Maximum Single Dose - optional = 500 as the stated inputs, the result is Calculated Single Dose = 1,125 mg, Calculated Total Daily Dose = 2,250 mg/day and Single Dose = 500 mg. Each value corresponds to the declared output fields.
Example 2: Ibuprofen for Child — 32 kg, Fever
Inputs
With Patient Weight = 32, Dose per kg = 10, Doses per Day = 3 and Maximum Single Dose - optional = 400 as the stated inputs, the result is Calculated Single Dose = 320 mg, Calculated Total Daily Dose = 960 mg/day and Single Dose = 320 mg. Each value corresponds to the declared output fields.
Example 3: Enoxaparin for Adult — 85 kg, DVT Treatment
Inputs
With Patient Weight = 85, Dose per kg = 1, Doses per Day = 2 and Maximum Single Dose - optional = 100 as the stated inputs, the result is Calculated Single Dose = 85 mg, Calculated Total Daily Dose = 170 mg/day and Single Dose = 85 mg. Each value corresponds to the declared output fields.
Example 4: Acetaminophen — Adult, Post-Operative Pain
Inputs
With Patient Weight = 70, Dose per kg = 15, Doses per Day = 4 and Maximum Single Dose - optional = 1,000 as the stated inputs, the result is Calculated Single Dose = 1,050 mg, Calculated Total Daily Dose = 4,200 mg/day and Single Dose = 1,000 mg. Each value corresponds to the declared output fields.
Common Use Cases
- Calculate weight-based dose for antibiotics and other medications
- Verify correct pediatric dosing from weight
- Check if calculated dose exceeds maximum safe dose
- Calculate dose for ibuprofen, acetaminophen, amoxicillin
