Prednisolone Pediatric Dose Calculator by Weight
Use this prednisolone pediatric dose calculator support page when a clinician already selected the mg/kg/day target, dosing frequency, and duration. It converts the prescribed weight-based plan into mL for common 15 mg/5 mL liquid and points back to the main calculator for patient-specific inputs.
Use the prescribed plan first
Accuracy boundary
The formula and example are for concentration conversion after a clinician has chosen the dose. The linked calculator still requires weight entry and final clinical verification.
Quick answer
- Prednisolone 15 mg/5 mL equals 3 mg/mL.
- mL per dose = prescribed prednisolone mg per dose / 3.
- For pediatric burst plans, confirm the mg/kg/day target, frequency, duration, and max dose before converting to mL.
- Use the calculator to check the math, not to choose or extend a steroid course without reassessment.
Prednisolone 15 mg/5 mL formula
mL per dose = prednisolone mg per dose / 3 mg per mL.
- The calculator maps selected mg/kg/day targets into one or two daily doses.
- For asthma or croup burst plans, verify the prescribed course length and max daily dose before relying on the mL output.
- Give with food when possible and follow the prescribed duration.
Prednisolone quick conversion
Worked example
- Example only: a 20 kg child has a prescribed prednisolone plan of 1 mg/kg/day once daily.
- 20 kg x 1 mg/kg/day = 20 mg per day.
- 20 mg / 3 mg per mL = 6.7 mL per dose of 15 mg/5 mL liquid.
Safety checks before measuring
- Confirm the maximum dose and number of days before giving the first dose.
- Short bursts usually do not need a taper unless the prescriber says so.
- Call promptly for worsening breathing, repeated vomiting, severe mood changes, or concerning infection symptoms.
Frequently asked questions
Start with the prescribed mg/kg/day target, the child's weight, the dosing frequency, and the maximum daily dose. The calculator converts that plan into mg and mL for the selected liquid strength.
There are 3 mg in 1 mL because 15 mg divided by 5 mL equals 3 mg/mL.
No. Use the prescribed mg/kg/day target, duration, and maximum dose. This page helps convert that plan into mL.
Verify the indication, weight, liquid concentration, frequency, course length, max daily dose, and whether reassessment is needed before repeating or extending a steroid burst.
