Ben-u-ron dose calculator by weight

Every weight from 5 to 40 kg, in milligrams and in millilitres according to the strength of your bottle. Fixed table from the AEPap dosing guide — no AI. Always check the strength printed on your own bottle: it changes by country and by presentation.

⚠️ The grey rows are below the minimum weight for Paracetamol (acetaminophen): do not give it without medical advice. Under 3 months, no medicine without a prescription.

The guide publishes a band of 10–15 mg/kg per dose. This table uses 15 mg/kg: it is the dose the published daily maximum is built from, and the one the manufacturers' leaflets give. A lower dose within the band is also correct.

Under 3 months, only if a doctor has told you to. Do not combine with other products that also contain paracetamol (cold remedies).

What parents ask about Ben-u-ron

How much Ben-u-ron for a child of 10, 15 or 20 kg?

The dose goes by weight, never by age alone. For Ben-u-ron:

10 kg 150 mgsyrup 200 mg/5 ml (4 %): 3.7 ml
15 kg 225 mgsyrup 200 mg/5 ml (4 %): 5.6 ml
20 kg 300 mgsyrup 200 mg/5 ml (4 %): 7.5 ml

How often, and how many times a day?

Every 4–6 hours. For a child of 15 kg that is at most 4 doses in 24 hours.

What if I don't know what the child weighs?

Age is not enough: two children of the same age can be several kilos apart, and this dose is calculated per kilo. Weigh the child, or ask at the pharmacy. PediBot will not give a figure from age alone.

From what age can Ben-u-ron be given?

Under 3 months, only if a doctor has told you to. Do not combine with other products that also contain paracetamol (cold remedies).

Sold in Germany and Portugal.
