The revised Summary of Product Characteristics for Perfalgan provides a recommended dose for both adults and children according to four different weight bands: <10kg; >10kg to <33kg; >33kg to <50kg; and >50kg. For the >50kg weight band the recommended maximum daily dose is dependent on the presence or absence of additional risk factors for hepatotoxicity.

Doses are presented in both milligrams per kilogram and millilitres per kilogram with a recommendation that prescribers state the total dose in both milligrams and volume to avoid dosing errors.
