It has been given intramuscularly or intravenously in usual doses of 1 to 2 g every 4 hours up to 4 times daily if necessary, to a maximum dose of 8 g daily, for the treatment of pain and fever. For doses in children, see below.

Adverse effects.

Occupational contact dermatitis has been reported in healthcare professionals after preparing injections of propacetamol.1-3 Propacetamol is the hydrochloride of N,N-diethylglycine ester with paracetamol and the results of a study4 have suggested that allergic reactions to propacetamol are related to sensitisation to the activated ester rather than to paracetamol itself.
