Duration of treatment
If symptoms do not improve after seven days, the clinical situation should be reviewed.
Hypersensitivity to the active substance or any of the excipients listed in section 6.1, including methyl parahydroxybenzoate (E218) and propyl parahydroxybenzoate (E216) (see section 4.4).
4.4 Special warnings and precautions for use
As with all medicines, it is recommended to limit the treatment duration as much as possible. If symptoms do not improve after seven days, the clinical situation should be reviewed.
Each 10 ml dose has a sodium content of 141 mg (6.2 mmol). This should be taken into account when a highly restricted salt diet is recommended.
Calcium: Each dose contains 160 mg of calcium carbonate. Care needs to be taken in treating patients with hypercalcaemia, nephrocalcinosis and recurrent calcium containing renal calculi.
Contains methyl parahydroxybenzoate (E218) and propyl parahydroxybenzoate (E216) which may cause allergic reactions (possibly delayed).
4.5 Interaction with other medicinal products and other forms of interaction
Due to the presence of calcium and carbonates, a time-interval of 2 hours should be considered between Gaviscon intake and the administration of other medicinal products, especially tetracyclines, fluoroquinolones, iron salts, thyroid hormones, chloroquine, biphosphonates, and estramustine. See also 4.4.
4.6 Fertility, pregnancy and lactation
Clinical studies in more than 500 pregnant women as well as a large number of data from post-marketing experience indicate no malformative nor feto/ neonatal toxicity of the active substances. Gaviscon can be used during pregnancy, if clinically needed.
Pre-clinical investigations have revealed alginate has no negative effect on parental or offspring fertility or reproduction. No effects of the active substances have been shown in breastfed newborns/infants of treated mothers. Gaviscon can be used during breast-feeding.
Clinical data do not suggest that Gaviscon has an effect on human fertility.
4.7 Effects on ability to drive and use machines
Gaviscon has no or negligible influence on the ability to drive and use machines.
4.8 Undesirable effects
Adverse reactions have been ranked under headings of frequency using the following convention:
Very rare: < 1/10,000
Not known (cannot be estimated from the available data).
Immune system disorders:
Very rare: Anaphylactic and anaphylactoid reactions. Hypersensitivity reactions such as urticaria.
Respiratory, thoracic and mediastinal disorders:
Very Rare: Respiratory effects such as bronchospasm.

5.1 Pharmacodynamic properties
Pharmacotherapeutic group: Other drugs for peptic ulcer and gastro-oesophageal reflux disease (GORD); ATC Code: A02BX
On ingestion Gaviscon Suspension reacts with gastric acid to form a raft of alginic acid gel having a near neutral pH and which floats on the stomach contents effectively impeding gastro-oesophageal reflux. In severe cases the raft itself may be refluxed into the oesophagus in preference to the stomach contents and exert a demulcent effect.
5.2 Pharmacokinetic properties
The mode of action of Gaviscon Suspension is physical and does not depend on absorption into the systemic circulation.
5.3 Preclinical safety data
No preclinical findings relevant to the prescriber have been reported.
