Overview
How does Gaviscon Double Action Liquid treat heartburn and indigestion?
Gaviscon Double Action Liquid is an oral suspension formulated to deliver dual relief from gastro-oesophageal reflux and acid indigestion. It contains three active ingredients: sodium alginate, sodium bicarbonate, and calcium carbonate. Upon reaching the stomach, the sodium alginate reacts with gastric acid to form a thick, protective gel raft that floats on top of the stomach contents. This physical barrier physically blocks acid, pepsin, and bile from traveling back up into the oesophagus, preventing the painful burning sensation associated with heartburn. Simultaneously, the antacid components, sodium bicarbonate and calcium carbonate, quickly neutralise excess gastric acid, relieving pain and discomfort caused by indigestion.
What are the benefits of a liquid suspension formula over solid tablets?
The primary advantage of this liquid preparation is its speed of action and surface coverage. As a liquid, the active ingredients begin working immediately upon reaching the stomach without requiring time to dissolve or break down, which is essential for fast-acting symptom management. The suspension coats the delicate mucosal lining of the oesophagus as it is swallowed, offering instant soothing relief to inflamed tissues. Additionally, liquid formulations ensure an even distribution of alginate particles across the stomach contents, resulting in a more uniform and stable protective raft compared to chewable options.
How does Gaviscon Double Action Liquid provide long-lasting relief?
Unlike basic antacids that only briefly lower stomach acidity, this product addresses both the chemical and mechanical causes of reflux. The alginate raft remains intact over the stomach contents for up to 4 hours, maintaining a physical shield even during active digestion or when lying down. By continuously preventing stomach contents from irritating the lower oesophageal sphincter and surrounding tissue, the formulation allows sensitive mucosal membranes time to heal, breaking the cycle of recurring post-meal inflammation.
Active Ingredients
Sodium alginate, sodium bicarbonate, and calcium carbonate
Usage Instructions
How should Gaviscon Double Action Liquid be taken for best results?
Shake the bottle well before use to ensure the active suspension is fully blended. For adults and children aged 12 years and over, the recommended dosage is 10ml to 20ml (two to four 5ml spoonfuls) taken after meals and at bedtime, up to four times per day. Do not exceed the recommended dose. If symptoms persist after 7 days of continuous treatment, consult a healthcare practitioner for a full medical evaluation.
Warnings
What safety precautions should be kept in mind when using this medicine?
This product contains sodium and calcium compounds, which must be taken into account by individuals on a strictly restricted sodium diet or those with hypercalcaemia, nephrocalcinosis, or recurrent calcium-containing kidney stones. Due to its acid-neutralising effect, taking this liquid alongside other oral medications can interfere with their absorption; allow an interval of at least 2 hours between taking this product and other oral medicines, particularly tetracyclines, fluoroquinolones, iron salts, and ketoconazole. If severe pain or persistent digestive symptoms occur, discontinue use and speak to a doctor. Store below 30 degrees Celsius, do not refrigerate or freeze, and keep out of the reach and sight of children.
Who Is It For
Who is the intended user for this product?
This oral liquid is suitable for adults and children aged 12 years and older who experience symptoms of acid reflux, heartburn, or indigestion following meals, during pregnancy, or when lying down at night. It is an ideal option for individuals seeking immediate, dual-action relief that both neutralises acid and creates a physical reflux barrier. Pregnant and breastfeeding women can safely use this formulation, as its primary mechanism is physical rather than systemic. Children under 12 years of age should only take this product under medical supervision.
