Bisodol Indigestion Relief Tablets
Sodium Bicarbonate Ph.Eur.
Calcium Carbonate Ph.Eur.
Magnesium Carbonate Light Ph.Eur.
Chewable tablet for oral administration.
For relief of the symptoms of gastric hyperacidity, variously called indigestion, heartburn, dyspepsia and flatulence.
Adults, elderly and children over 12 years:
Suck slowly or chew one or two tablets as required.
Children under 12 years:
Hypophosphataemia, and avoid in patients with heart failure or renal failure.
If symptoms persist, consult your doctor.
Keep all medicines out of the reach of children.
Not to be taken during the first three months of pregnancy.
This medicine contains less than 1 mmol sodium (23 mg) per tablet, that is to say essentially 'sodium-free'.
Antacids are known to reduce the absorption of certain medicines including tetracyclines and iron salts.
Animal studies are insufficient with respect to effects on pregnancy/embryonal/foetal development/parturition and postnatal development.
Caution should be exercised when prescribing to pregnant women.
Calcium salts can have a constipating effect and magnesium salts can have a laxative effect. The specific mixture of antacids is intended to avoid the lower gastrointestinal effects seen with single antacid preparations. No side effects associated with sodium bicarbonate except when taken in excess.
Rebound hyperacidity may occur with prolonged dosage.
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 website at: www.mhra.gov.uk/yellowcard or search for MHRA Yellow Card in the Google Play or Apple App Store.
Hypermagnesaemia – intravenous administration of calcium salts.
Hypernatraemia – give plenty of salt free fluids.
Hypercalcaemia – remove source of calcium.
Sodium bicarbonate, calcium carbonate and magnesium carbonate are antacids. They act by neutralising the hydrochloric acid produced by the stomach and thus reducing gastric and duodenal irritation.
Calcium carbonate is converted to calcium chloride by gastric acid. Some of the calcium is absorbed from the intestines but about 85% is reconverted to insoluble calcium salts, such as the carbonate and is excreted in the faeces.
Magnesium carbonate reacts with gastric acid to form soluble magnesium chloride and carbon dioxide in the stomach. Some magnesium is absorbed but is usually excreted rapidly in the urine.
Administration of sodium bicarbonate by mouth causes neutralisation of gastric acid with the production of carbon dioxide. Bicarbonate not involved in that reaction is absorbed and in the absence of a deficit of bicarbonate in the plasma, bicarbonate ions are excreted in the urine that is rendered alkaline with an accompanying diuresis.
The active ingredients in Bisodol Indigestion Relief Tablets have a well documented safety record.
