From the Research
The typical dosing frequency for Gaviscon Dual Action Liquid is 10-20 ml taken after meals and at bedtime, usually 4 times daily. Adults and children 12 years and older should take 10-20 ml after meals and before bedtime, while children 6-12 years old should take 5-10 ml after meals and at bedtime. The medication works quickly by forming a protective barrier (raft) that floats on top of stomach contents, preventing acid and food from flowing back into the esophagus. This provides relief from heartburn, acid reflux, and indigestion symptoms. The dual action comes from the combination of alginic acid, which forms the protective raft, and antacids (aluminum hydroxide and magnesium carbonate) that neutralize stomach acid. For maximum effectiveness, the dose should be taken after eating and before lying down, as these are times when reflux is most likely to occur. If symptoms persist beyond 7 days of regular use, medical advice should be sought.
According to a study published in 2017 1, Gaviscon Dual Action Liquid was effective in reducing breakthrough GERD symptoms when added to proton pump inhibitor therapy. The study found that patients who took Gaviscon had significantly greater reductions in heartburn and regurgitation symptoms compared to those who took a placebo. Another study published in 2014 2 found that Gaviscon Double Action Liquid was more effective than an antacid without alginate in controlling post-prandial oesophageal acid exposure.
Key points to consider when prescribing Gaviscon Dual Action Liquid include:
- Dosage: 10-20 ml taken after meals and at bedtime, usually 4 times daily
- Age restrictions: Adults and children 12 years and older should take 10-20 ml, while children 6-12 years old should take 5-10 ml
- Mechanism of action: Forms a protective barrier (raft) that floats on top of stomach contents, preventing acid and food from flowing back into the esophagus
- Efficacy: Effective in reducing breakthrough GERD symptoms and controlling post-prandial oesophageal acid exposure
- Safety: Well-tolerated and safe for use in pregnant women, as shown in a study published in 1988 3.
It is essential to note that while Gaviscon Dual Action Liquid is effective in managing GERD symptoms, it should not be used as a substitute for medical advice. If symptoms persist beyond 7 days of regular use, patients should seek medical advice to rule out any underlying conditions that may require further treatment.
