This calculator determines the Paracetamol dose for treating pain and fever, using a concentration of Paracetamol 120 mg/5 mL (24 mg/mL), based on the patient’s weight and age group:
Dose in mL and mg (based on Paracetamol):
Pediatric ≥ 3 months: 10 to 15 mg/kg/dose po every 4 to 6 hours prn (Max: 5 doses per day)
Adults: Usual dose is 13.5 mL (325 mg) to 27 mL (650 mg) po every 4 to 6 hours prn (Max 4 g/24 hrs)
Where:
Administer as prescribed for pain or fever. ⚠️ Always consult a healthcare provider.
Enter the patient’s weight in kilograms or pounds, select the unit, choose the age group, and click "Calculate." The calculator provides the dose in mL and mg (Paracetamol) for pediatric and adult patients.
Example: Weight 15 kg, Pediatric ≥ 3 months:
Pediatric ≥ 3 months: 6.3 mL (150 mg) to 9.4 mL (225 mg) po every 4 to 6 hours to a maximum of 5 doses per day prn Max daily dose: 46.9 mL/day (1125 mg/day) Usual adult dose: 13.5 mL (325 mg) to 27 mL (650 mg) po every 4 to 6 hours prn (Max 166.7 mL/4 g/24 hrs) Calculations must be re-checked and should not be used alone...
