Warnings & precautions in children

Not for organic acid disorders. Depending on the plasma concentration if possible. A properly running infusion is needed because of necrosis in the event of extravasation. Nausea: give a strong antiemetic beforehand. Watch out for hypernatraemia.

The taste of oral sodium benzoate is very unpleasant, so taking it at mealtimes is difficult. It should therefore preferably be taken immediately after a meal.
