Gaviscon Advance is an oral medicine used to relieve heartburn, acid reflux, indigestion, and symptoms of gastroesophageal reflux disease (GERD). Unlike medicines that reduce the production of stomach acid, Gaviscon Advance works by forming a protective barrier over the stomach contents, helping prevent acid from flowing back into the food pipe (esophagus). This provides fast relief from the burning sensation associated with acid reflux while also protecting the lining of the esophagus.
Gaviscon Advance is commonly recommended for people experiencing frequent heartburn after meals, nighttime reflux, indigestion during pregnancy (under medical advice), and persistent acid regurgitation. It is available as an oral suspension and chewable tablets in many countries.
Primary Uses
- Heartburn
- Acid reflux (GERD)
- Indigestion (Dyspepsia)
- Acid regurgitation
- Sour taste in the mouth due to reflux
- Night-time reflux symptoms
- Reflux symptoms during pregnancy (when recommended by a healthcare professional)
Indigestion can have different underlying causes. While Gaviscon Advance is mainly useful when symptoms are related to acid reflux, symptoms such as bloating, early fullness after eating, nausea, and post-meal heaviness may sometimes be associated with reduced stomach motility or functional dyspepsia. In selected cases, doctors may prescribe a prokinetic medicine such as ITP 50mg Tablet (itopride) to help improve gastrointestinal movement.
How Gaviscon Advance Works
Gaviscon Advance contains sodium alginate and potassium bicarbonate. When the medicine comes into contact with stomach acid, it forms a thick, gel-like protective “raft” that floats on top of the stomach contents. This barrier helps prevent acid from moving back into the esophagus while also neutralizing some stomach acid, reducing irritation and providing long-lasting symptom relief.
How to Take
- Take exactly as directed by your doctor or according to the product label.
- It is generally taken after meals and at bedtime for optimal symptom control.
- Shake the bottle well before use if using the liquid formulation.
- Measure the liquid with the supplied measuring cup or spoon.

Possible Side Effects
Gaviscon Advance is generally well tolerated. However, some people may experience:
- Nausea

Precautions
Before using Gaviscon Advance, inform your healthcare provider if you:
- Have kidney disease
- Have heart failure or need a low-sodium diet
- Have high blood calcium levels

- Are pregnant or breastfeeding
If symptoms persist for more than two weeks, worsen, or are accompanied by difficulty swallowing, unexplained weight loss, vomiting blood, or black stools, seek medical evaluation promptly.
Drug Interactions
Gaviscon Advance may reduce the absorption of certain medicines. To minimize interactions, it is generally recommended to take other oral medications at least 2 hours before or after Gaviscon Advance.
Examples include:
- Levothyroxine
- Iron supplements
- Certain antibiotics (e.g., tetracyclines and fluoroquinolones)
- Bisphosphonates
- Some antifungal medicines
Frequently Asked Questions
Is Gaviscon Advance an antacid?
It has antacid properties but primarily works by creating a protective alginate barrier that helps prevent acid reflux.
Can I take Gaviscon Advance every day?
It may be used as directed, but frequent or long-term symptoms should be assessed by a healthcare professional to identify the underlying cause.
Can Gaviscon Advance be used during pregnancy?
It is commonly used for pregnancy-related heartburn, but it should only be taken after consulting your doctor or obstetrician.
Does Gaviscon Advance cure GERD?
No. It helps relieve symptoms but does not cure gastroesophageal reflux disease.
Gaviscon Advance vs. Gaviscon Syrup: What’s the Difference?
Many people confuse Gaviscon Advance with the regular Gaviscon Syrup, but the two formulations are not exactly the same.
Gaviscon Syrup (Regular Gaviscon) typically contains sodium alginate, sodium bicarbonate, and calcium carbonate. It helps neutralize stomach acid while also forming a protective barrier over the stomach contents to reduce acid reflux and heartburn.
Gaviscon Advance, on the other hand, contains a higher concentration of sodium alginate and potassium bicarbonate. The increased alginate content produces a stronger and more durable protective barrier (“raft”), making it particularly effective for people with frequent or severe acid reflux (GERD) and nighttime reflux symptoms.
