This paracetamol dosage calculator can help you determine the safe paracetamol dosage for a children by their weight. It works similarly to our dosage calculator, but the equation already has the recommended pediatric dose of paracetamol.
If your child is sick, you might also be interested in alleviating their pain with ibuprofen. In that case, check out our ibuprofen dosage calculator.
Paracetamol dosage for children by weight
The regularly prescribed analgesic and antipyretic oral or rectal dose of paracetamol for children over 3 months is
10 to 15 mg per 1 kilogram of body weight
It can be administered every 4 to 6 hours, with a maximum of 5 doses in 24 hours. The maximal daily pediatric dose of paracetamol is
According to some sources, rectal administration of drugs is less effective, but it's been proven that the same oral and rectal paracetamol dosages have comparably effective antipyretic properties. That's why the recommended doses of the drug are identical in both liquid form and as a suppository. Read more about it here.
If you think your child needs more than the maximal dose, it's possible to use paracetamol and ibuprofen alternately. Please consult your pediatrician before administering more drugs to your child.
How does the paracetamol calculator work?
Let's assume that your child is four years old and weighs 20 kg. First, the paracetamol calculator will estimate these figures:
- The single pediatric dose of paracetamol:
20 kg * 15 mg/kg = 300 mg
- The maximum daily dose for your child:
20 kg * 60 mg/kg = 1200 mg
Pills are hard to swallow for children, so paracetamol for pediatric use is usually found in liquid form. You can choose either from Infant solution, Six-plus solution, Tablet and Custom solution.
If you decide on the last option, it's very important to determine the dosage precisely, especially with small children. Check the solution strength in
mg/mL on the drug packaging, type it in and the paracetamol calculator will calculate these values:
- Single dose solution amount:
300 mg / 10 mg/mL = 30 mL
- Maximum daily amount of solution:
1200 mg / 10 mg/mL = 120 mL
Make sure you measure the liquid form of paracetamol with a special dose-measuring spoon or cup. It would be unwise to rely on a tablespoon, as they come in all shapes and sizes.
