As with other antacid products, taking Gaviscon Double Action Mixed Berries Flavour Oral Suspension can mask the symptoms of other more serious, underlying medical conditions.
Gaviscon Double Action Mixed Berries Flavour Oral Suspension should not be used in the following cases:
• Patients with severe/impaired renal function/-insufficiency
• Patients with hypophosphatemia
There is a possibility of reduced efficacy in patients with very low levels of gastric acid.
There is increased risk for hypernatremia in children with gastroenteritis or suspected renal insufficiency.
Treatment of children younger than 12 years of age is not generally recommended, except on medical advice.
Due to the presence of calcium and carbonates which acts as an antacid, a time-interval of 2 hours should be considered between Gaviscon intake and the administration of other medicinal products, especially H2-antihistaminics, tetracyclines, digoxine, fluoroquinolone, iron salts, thyroid hormones, ketoconazole, neuroleptics, thyroxine, penicilamine, beta-blockers (atenolol, metoprolol, propanolol), glucocorticoid, chloroquine, estramustine and diphosphonates. See also section 4.4.
A moderate amount of data on pregnant women (between 300-1000 pregnancy outcomes) indicate no malformative or feto/neonatal toxicity of the active substances.
Based on this and previous experience, the medicinal product may be used during pregnancy and lactation, if clinically needed.
Nevertheless, taking into account the presence of calcium carbonate it is recommended to limit the treatment duration as much as possible.
No effects of the active substances have been shown in breastfed newborns/infants of treated mothers. This product can be used during breast-feeding.
Pre-clinical animal investigations have revealed alginate has no negative effect on parental or offspring fertility or reproduction.
Clinical data do not suggest that this product has an effect on human fertility
This product has no or negligible influence on the ability to drive and use machines.

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: www.mhra.gov.uk/yellowcard or search for MHRA Yellow Card in the Google Play or Apple App Store.
Some abdominal distension may be noticed.
In the event of overdosage symptomatic treatment should be given.
Pharmacotherapeutic group: A02BX, Other drugs for peptic ulcer and gastro-oesophageal reflux disease.
The medicinal product is a combination of two antacids (calcium carbonate and sodium hydrogen carbonate) and an alginate.
On ingestion, the medicinal product reacts rapidly with gastric acid to form a protective barrier (raft) of alginic acid gel having a near neutral pH and which floats on the stomach contents. Effective impediment of gastro-oesophageal reflux may last for up to 4 hours. In severe cases the raft itself may be refluxed into the oesophagus, in preference to the stomach contents and exert a demulcent effect.
Calcium carbonate neutralises gastric acid to provide fast relief from indigestion and heartburn. This effect is increased by the addition of sodium hydrogen carbonate which also has a neutralising action. The total neutralising capacity of the product at the lowest dose of 10 ml is approximately 10 mEqH+.
The mode of action of the medicinal product is physical and does not depend on absorption into the systemic circulation.
There are no preclinical data of relevance to the prescriber, which are additional to those already included in other sections of the SmPC
