Long-Lasting Relief from Heartburn and Acid Reflux
Gaviscon Advance Chewable Tablets Peppermint Overview
Gaviscon Advance Chewable Tablets Peppermint are an alginate-based reflux treatment used to relieve heartburn, acid reflux, and indigestion. They work by forming a protective barrier on top of stomach contents, helping to prevent acid from flowing back into the oesophagus.
In the UK, Gaviscon Advance is an over-the-counter medicine and is often recommended for people with frequent or persistent reflux symptoms, including those who need stronger protection than standard antacids.
Understanding Acid Reflux and Heartburn
What causes reflux?
Acid reflux occurs when stomach acid moves upwards into the oesophagus due to relaxation or weakness of the lower oesophageal sphincter (LOS). This allows acidic stomach contents to irritate the lining of the oesophagus, causing a burning sensation commonly known as heartburn.
Reflux symptoms are often triggered by large meals, spicy or fatty foods, alcohol, pregnancy, obesity, or lying down soon after eating.
Why symptoms can be persistent
Unlike occasional indigestion, reflux symptoms may recur regularly, particularly at night or after meals. Repeated acid exposure can irritate the oesophagus and significantly affect comfort and quality of life.
What Are Gaviscon Advance Chewable Tablets?
Gaviscon Advance Chewable Tablets contain a high concentration of sodium alginate combined with potassium bicarbonate. Unlike simple antacids that neutralise acid, Gaviscon Advance works by forming a physical barrier, often referred to as a “raft”.
The peppermint-flavoured chewable format provides a convenient alternative to liquid formulations while delivering the same protective effect.
How Do Gaviscon Advance Chewable Tablets Work?
Alginate raft mechanism
After chewing and swallowing, the alginate reacts with stomach acid to form a gel-like layer that floats on top of the stomach contents. This barrier helps prevent acid from refluxing into the oesophagus, particularly when lying down.
How this differs from standard antacids
Standard antacids neutralise stomach acid temporarily. Gaviscon Advance focuses on preventing reflux itself, which can provide longer-lasting symptom relief, especially for post-meal and night-time symptoms.

What it does not treat
Gaviscon Advance does not:

Ongoing reflux should be medically assessed.
Who Are Gaviscon Advance Chewable Tablets For?
Gaviscon Advance may be suitable for:
- adults and adolescents aged 12 years and over
- people with frequent or troublesome reflux symptoms
- individuals who prefer chewable tablets over liquids
It is often recommended where standard antacids have not provided sufficient relief.
Who Should Avoid Gaviscon Advance
Gaviscon Advance may not be suitable if:
- you are on a strict low-sodium or low-potassium diet

- you are allergic to any of the ingredients
A pharmacist can advise on suitability, particularly for long-term use.
How to Take Gaviscon Advance Chewable Tablets
Dosage
- Chew 1 to 2 tablets thoroughly after meals and at bedtime
- Use up to four times daily, if needed
Important usage advice
- Chew tablets completely before swallowing
- Do not exceed the recommended dose
- Leave a gap between Gaviscon and other medicines if advised
Safety, Warnings and Side Effects
Gaviscon Advance is generally very well tolerated.
Some people may experience mild side effects such as bloating or nausea. These effects are usually short-lived.
Because it contains sodium and potassium, caution is advised in people with certain medical conditions.
When to Seek Medical Advice
Speak to a GP or pharmacist if:
- symptoms persist for more than 7 days
- heartburn is severe or worsening
- you have difficulty swallowing
- you experience unexplained weight loss or persistent vomiting
These may indicate a more serious condition requiring investigation.
Use in Pregnancy and Breastfeeding
Gaviscon Advance is commonly used during pregnancy to relieve reflux and heartburn. Pregnant or breastfeeding women should still seek advice before use.
How Gaviscon Advance Compares to Other Reflux Treatments
Gaviscon Advance vs standard Gaviscon
Gaviscon Advance contains a higher alginate concentration, providing a stronger and longer-lasting protective barrier.
Gaviscon Advance vs acid-suppressing medicines
Medicines such as proton pump inhibitors reduce acid production but take time to work. Gaviscon Advance provides rapid physical protection and can be used alongside other treatments if advised.
Supporting Reflux Management
Lifestyle measures can help reduce reflux symptoms, including eating smaller meals, avoiding trigger foods, not lying down after eating, elevating the head of the bed, and maintaining a healthy weight.
