Paediatric Max Dose Cap Calculator
Calculate mg/kg dosing and automatically apply a maximum dose cap (e.g., "10 mg/kg, max 200 mg"). Optionally convert the capped dose to mL using concentration (mg/mL).

How “Max Dose Cap” Works
Many paediatric prescriptions include a ceiling dose such as: “10 mg/kg, max 200 mg per dose.” This means you calculate the weight-based dose first, then apply the maximum cap if the calculated dose exceeds it.
If you also know the medication concentration (mg/mL), you can convert the capped dose (mg) into a volume (mL) for drawing up.

Worked Examples
Example 1 (capped): 25 kg, 10 mg/kg, max 200 mg. What is the final dose?
Final = MIN(250, 200) = 200 mg
Example 2 (not capped): 18 kg, 5 mg/kg, max 200 mg. What is the final dose?
Final = MIN(90, 200) = 90 mg
Example 3 (capped + volume): 25 kg, 10 mg/kg, max 200 mg, concentration 50 mg/mL.
Volume = 200 ÷ 50 = 4 mL
Clinical safety note: Always confirm the maximum dose and frequency in your local guideline/product information, and apply independent double-checks for high-risk medications.
