4.3 Contraindications

This medicinal product is contraindicated in patients with known or suspected hypersensitivity to sodium alginate, sodium bicarbonate, and calcium carbonate or to any of the excipients listed in section 6.1.

4.4 Special warnings and precautions for use

If symptoms do not improve after seven days, the clinical situation should be reviewed.

This medicinal product contains 126.5 mg sodium per tablet, equivalent to 6.3 % of the WHO recommended maximum daily intake for sodium.

The maximum daily dose of this product is equivalent to 50.6 % of the WHO recommended maximum daily intake for sodium. This is based on a two-tablet dose taken four times per day.

This medicinal product is considered high in sodium. This should be particularly taken into account for those on a low salt diet.

Each tablet contains 160 mg (1.6 mmol) of calcium carbonate. Care needs to be taken in treating patients with hypercalcaemia, nephrocalcinosis and recurrent calcium containing renal calculi.

This medicine contains 7.5 mg aspartame in each tablet. Aspartame is hydrolysed in the gastrointestinal tract when orally ingested. One of the major hydrolysis products is phenylalanine. Due to its aspartame content this medicinal product should not be given to patients with phenylketonuria.

Patients with rare hereditary problems of fructose intolerance, glucose-galactose, malabsorption or sucrase-isomaltase insufficiency should not take this medicine.

For children below 12 years, please see section 4.2.
