A medical review of the patient's condition should be undertaken seven days after initiating treatment or before if symptoms worsen.

Follow dosage instructions exactly to avoid an excessive amount of product per feed and the possible risk of hypernatraemia.

Not to be used when treating infants with known or suspected impairment of renal function as the sodium content (approximately 21 mg or 0.92 mmol per dose) may add to the risk of hypernatraemia.

Hypernatraemia should be treated with oral fluids and monitoring of the infant's electrolytes. Severe cases should be treated by the cautious use of hypo-osmotic solutions.

Reporting of Suspected Adverse Reactions

4.9 Overdose

Symptoms

Overdosage with Gaviscon Infant may lead to the formation of an intragastric mass.

Rare instances have occurred in which an intragastric mass has developed comprising Gaviscon Infant and milk proteins. Overdosage may have contributed to the development of such masses. The majority resolved spontaneously when the child was admitted to hospital, Gaviscon Infant was discontinued and a regime of adequate fluid intake and monitoring of fluid and electrolyte balance was installed. If spontaneous resolution of the mass does not occur, removal by surgical or endoscopic means may be required.

Management

In the event of overdose, symptomatic treatment should be given.
