What Is Gaviscon?
Gaviscon is an antacid + alginate combination that provides fast relief for acid reflux and heartburn. It's different from regular antacids — it forms a foam layer in the stomach that physically stops acid from rising into the esophagus.
What Is Gaviscon Used For?
- Heartburn — a burning sensation in the chest
- Acid reflux/GERD — sour fluid rising into the throat
- Indigestion especially after meals
- Pregnancy heartburn — very common and a safe treatment
- Occasional acidity — after eating spicy or heavy food
How Does Gaviscon Work?
Gaviscon contains both an antacid (neutralizes acid) and an alginate (foaming agent). Once in the stomach, it forms a protective foam raft that floats on top of stomach contents — mechanically preventing acid from flowing back into the esophagus.
Dosage
- Adults: 10-20ml, after meals and before bed
- Maximum: 4 times per day (check the label for exact instructions)
- Take while upright, don't lie down immediately after
Gaviscon vs Omeprazole
| Gaviscon | Omeprazole |
| Immediate relief (minutes) | Takes 1-4 days to start working |
| Short-acting | Lasts up to 24 hours |
| For occasional heartburn | For GERD/ulcer |
| Forms a physical barrier | Reduces acid production |
Safety During Pregnancy
Gaviscon is generally considered safe during pregnancy because it isn't systemically absorbed — it only works locally in the stomach. Pregnancy heartburn is very common (especially in the 2nd-3rd trimester), and Gaviscon is a popular, trusted option. Still, confirm with your gynecologist.

Frequently Asked Questions
How quickly does Gaviscon work?
Gaviscon provides relief within minutes because it instantly forms a protective foam layer in the stomach that stops acid from rising into the esophagus. This differs from Omeprazole, which takes days to start working.
Is Gaviscon safe during pregnancy?
Yes, Gaviscon is generally considered safe during pregnancy because it isn't systemically absorbed — it only works locally in the stomach. It's a popular, trusted option for pregnancy heartburn, though you should confirm with your gynecologist.
What's the difference between Gaviscon and Omeprazole?
Gaviscon provides immediate relief for occasional heartburn by forming a physical barrier. Omeprazole reduces acid production at the source and lasts up to 24 hours — better suited for persistent conditions like GERD or ulcers.
When should Gaviscon be taken?
It's best taken after meals and before bed — when acid reflux risk is highest. Take it while upright and avoid lying down immediately afterward.
Can Gaviscon be used daily?
It's safe for occasional use, but if heartburn occurs more than twice a week, it could indicate GERD, which needs proper medical evaluation — don't rely on Gaviscon alone.
