This calculator determines the Paracetamol dose for treating pain and fever, based on the selected product strength (5 mg/1 mL or 5 mg/5 mL), 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, Max daily dose = 5 * maximum dose per administration) for weights ≤80 kg; for weights >80 kg, use 160 mL (800 mg) for 5 mg/1 mL or 800 mL (800 mg) for 5 mg/5 mL
Adults: Usual dose is 65 mL (325 mg) to 130 mL (650 mg) po every 4 to 6 hours prn (Max 5 doses per day, Max daily dose = 5 * maximum dose per administration, capped at 4 g/24 hrs) for 5 mg/1 mL, or 1625 mL (325 mg) to 3250 mL (650 mg) po every 4 to 6 hours prn (Max 5 doses per day, Max daily dose = 5 * maximum dose per administration, capped at 4 g/24 hrs) for 5 mg/5 mL
Where:
Administer as prescribed for pain or fever. ⚠️ Always consult a healthcare provider.
Select the product strength, 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 based on the selected strength.
Example: Product Strength Paracetamol 5 mg / 1 mL, Weight 10 kg, Pediatric ≥ 3 months:
Calculations are based on the product strength you selected: Paracetamol 5 mg / 1 mL Pediatric ≥ 3 months: 20 mL (100 mg) to 30 mL (150 mg) po every 4 to 6 hours to a maximum of 5 doses per day prn Max daily dose: 150 mL/day (750 mg/day) Example: Product Strength Paracetamol 5 mg / 5 mL, Weight 100 kg, Pediatric ≥ 3 months: 800 mL (800 mg) po every 4 to 6 hours to a maximum of 5 doses per day prn Max daily dose: 4000 mL/day (4000 mg/day) Usual adult dose: 65 mL (325 mg) to 130 mL (650 mg) po every 4 to 6 hours prn (Max 650 mL/3250 mg/24 hrs) for 5 mg/1 mL, or 1625 mL (325 mg) to 3250 mL (650 mg) po every 4 to 6 hours prn (Max 16,250 mL/3250 mg/24 hrs) for 5 mg/5 mL
Consult a healthcare provider before administering.
Paracetamol (Panadol; Calpol; Tylenol; Acetaminophen) is used to treat pain and fever.
Pediatric ≥ 3 months: 10 to 15 mg/kg/dose po every 4 to 6 hours prn (Max 5 doses/day, Max daily dose = 5 * maximum dose per administration) for weights ≤80 kg; for weights >80 kg, use 160 mL (800 mg) for 5 mg/1 mL or 800 mL (800 mg) for 5 mg/5 mL (Max 5 doses/day, Max daily dose: 800 mL/day or 4000 mL/day respectively). Adults: 325 to 650 mg/dose po every 4 to 6 hours prn (Max 5 doses/day, Max daily dose = 5 * maximum dose per administration, capped at 4 g/24 hrs).
Consult a doctor, as Paracetamol is not typically recommended for infants under 3 months without medical supervision.
Enter the weight in pounds, and the calculator will automatically convert it to kilograms for calculation (1 lb = 0.4536 kg approximately).
The maximum daily dose for pediatric patients (≥3 months) weighing over 80 kg is 800 mL (4000 mg) per 24 hours for 5 mg/1 mL, or 4000 mL (4000 mg) per 24 hours for 5 mg/5 mL.
