Sodium alginate + sodium hydrogen carbonate + calcium carbonate is used for symptoms of gastro-oesophageal reflux, heartburn, acid regurgitation and indigestion after meals. Alginate forms a floating barrier above the stomach contents, while sodium bicarbonate and calcium carbonate help neutralise acid.
It is taken by mouth, usually after meals and at bedtime, according to the leaflet. Suspension should be shaken before use, and chewable tablets should be chewed well if that is the product form. Do not exceed the recommended dose. If you follow a low-sodium diet or have high blood pressure, heart failure or kidney disease, check the sodium and calcium content.
Side effects are uncommon but may include bloating, nausea, constipation, diarrhoea or allergic reactions. High doses can increase calcium or sodium intake. Antacids may reduce absorption of some medicines, such as tetracyclines, quinolones, iron, levothyroxine or bisphosphonates, so a gap of several hours may be needed.
Consult a doctor if symptoms persist for more than 7–14 days, worsen, or if difficulty swallowing, weight loss, persistent vomiting, blood in vomit, black stools or chest pain occurs. During pregnancy and breastfeeding many products are commonly used, but medical advice is appropriate if symptoms are frequent or severe.
