Warnings & precautions in children

Sodium benzoate for tackling secondary hyperammonaemia is contraindicated in organic acid disorders. Patients with organic acid disorders have a tendency to develop hypokalaemia. Potassium levels must only be corrected if there is diuresis.

Formulations containing benzyl alcohol as a preservative should not be used in premature children and neonates because of the greater risk of toxic and anaphylactoid responses; caution is needed in children aged less than three years.
