4.3 Contraindications

Hypersensitivity to sodium alginate and magnesium alginate or any of the excipients listed in section 6.1.

Contraindicated in cases of intestinal obstruction and in cases of established diarrhoea.

Not to be used in situations where excessive water loss is likely, e.g. fever, diarrhoea, vomiting or high room temperature. Not to be used in gastroenteritis where the appropriate treatment is rehydration with fluid replacement.

Not to be used when treating infants with known or suspected impairment of renal function as the sodium content (approximately 23.9 mg or 1.04 mmol per dose) may add to the risk of hypernatraemia.

Not to be used except on a doctor or other health professional's recommendation.

4.4 Special warnings and precautions for use

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

Significant or sustained changes in bowel habit or stool consistency e.g. diarrhoea or constipation, should be investigated.

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 23.9 mg or 1.04 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.

This medicinal product contains 23.9 mg sodium per sachet, equivalent to 1% of the WHO recommended maximum daily intake of 2 g sodium for an adult. The maximum daily dose of this product is equivalent to 14 % of the WHO recommended maximum daily intake for sodium for an adult. This product is considered high in sodium. This should be particularly taken into account for those on a low salt diet.

4.5 Interaction with other medicinal products and other forms of interaction

Not to be used with thickening agents or infant milk preparations containing a thickening agent as this could lead to over-thickening of the stomach contents.

Reporting of Suspected Adverse Reactions

Reporting suspected adverse reactions after authorisation of the medicinal product is important. It allows continued monitoring of the benefit/risk balance of the medicinal product. Healthcare professionals are asked to report any suspected adverse reactions via the Yellow Card Scheme at: or search for MHRA Yellow Card in the Google Play or Apple App Store.

4.9 Overdose


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.


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