This product may interfere with the absorption of tetracyclines, chloroquine, penicillamine, phenothiazines and quinolone antibacterials, when these are given concomitantly.
There are no adequate human data from the use of aluminium hydroxide and magnesium hydroxide in pregnant women. Studies in animals have not been done. No data are available to suggest any harmful effects in pregnant women, associated with simethicone. Caution should therefore be exercised when taken by pregnant women.
Although some aluminium and magnesium may be secreted in breast milk, the concentration is too small to be harmful. Secretion of simethicone in the breast milk of nursing mothers has not been established but would be most unlikely
No adverse effects known.
May occasionally cause diarrhoea or constipation, although the combination of magnesium and aluminium salts minimises these gastrointestinal effects.
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
Symptoms of overdosage include nausea, vomiting, gastrointestinal irritation, diarrhoea/constipation. Treatment should be symptomatic and supportive.
Aluminium hydroxide and magnesium hydroxide have antacid properties and are used to neutralise gastric acid. Activated methylpolysiloxane (simethicone) has anti-foaming/deflatulent activity by virtue of its ability to change the surface tension of gas bubbles, thereby causing them to coalesce.
Magnesium hydroxide reacts with hydrochloric acid in the stomach to produce magnesium chloride. Small amounts of magnesium salts may be absorbed and excreted in the urine, otherwise excretion if via the faeces.
Aluminium hydroxide reacts with hydrochloric acid in the stomach to form aluminium chloride, some of which is absorbed. Absorbed aluminium is eliminated in the urine. The majority of aluminium remains in the gastrointestinal tract and forms insoluble poorly absorbed aluminium salts including hydroxide, phosphate, carbonate and fatty acid derivatives, which are excreted in the faeces.
There is no data availability on the pharmacokinetics of activated methylpolysiloxane.
There are no preclinical data of relevance to the prescriber which are additional to that already included.
