Summary
Calculate safe acetaminophen (paracetamol/Tylenol) doses for children by weight, formulation, and dosing interval.
How it works
- Enter the child's weight in kg or lbs (the tool converts automatically).
- Select the acetaminophen formulation you have on hand.
- The calculator applies the 10–15 mg/kg dosing range and caps the single dose at 1000 mg and the daily total at 4000 mg.
- Results show the dose in mg, the equivalent volume (mL) or tablet count, and how many doses are safe per day.
- A quick-reference weight table covers common weights from 5 kg to 30 kg.
Use cases
- Verify the correct Tylenol dose before giving it to a feverish child.
- Cross-check doses across different formulations when switching products.
- Determine max daily doses for multi-dose schedules in pediatric care.
- Educate parents on safe dosing ranges during a well-child visit.
