⚠️ 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).
