Summary

Calculate safe acetaminophen (paracetamol/Tylenol) doses for children by weight, formulation, and dosing interval.

How it works

  1. Enter the child's weight in kg or lbs (the tool converts automatically).
  2. Select the acetaminophen formulation you have on hand.
  3. 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.
  4. Results show the dose in mg, the equivalent volume (mL) or tablet count, and how many doses are safe per day.
  5. 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.
