What is Gaviscon Peppermint Liquid Relief?

Gaviscon Peppermint Liquid Relief is an over-the-counter medicine used to help relieve heartburn and acid indigestion. It is described as a reflux suppressant and is designed to create a soothing barrier against stomach acid.

The product is a peppermint-flavoured liquid. The original content also notes that it is sugar-free and gluten-free.

For the most accurate guidance, always check the current patient information leaflet that comes with the product.

What is it used for?

This medicine is mainly used to help with symptoms linked to excess stomach acid, including:

  • Heartburn
  • Acid indigestion
  • Acid reflux symptoms
  • Discomfort after meals

The original content states that it may provide relief within minutes after taking it.

How does it work?

Gaviscon Peppermint Liquid Relief works by forming a protective barrier that helps stop stomach acid from moving up into the oesophagus. This barrier action is why it is often used for reflux-type symptoms.

Because it acts locally in the digestive system, it is commonly taken after meals and at bedtime, according to the pack directions.

Who can take it?

According to the original content, this product is generally suitable for:

  • Adults
  • Children aged 6 years and over
  • Pregnant and breastfeeding women, subject to checking with a healthcare professional if needed

Anyone with a known allergy to any ingredient should avoid using it.

Who should be careful?

Extra caution is sensible if you:

  • Are taking other medicines
  • Have ongoing digestive symptoms
  • Have a medical condition that affects your diet or fluid intake
  • Are unsure whether the product is suitable for a child

If you are not sure whether it is appropriate, ask a pharmacist or doctor and check the leaflet before use.

How and when should it be taken?

The original content gives the following general dose ranges, but the pack instructions should always be followed:

Age group General guidance in the original content
Adults and children over 12 10–20 ml after meals and at bedtime
Children aged 6 to 12 5–10 ml after meals and at bedtime

Take it in line with the label or leaflet. The original content says it is usually taken after meals to help with symptom control.

What side effects can happen?

The original content lists these possible side effects:

  • Constipation
  • Diarrhoea
  • Stomach cramps

Most side effects mentioned are described as mild. If symptoms are severe, persistent, or worrying, seek medical advice.

If you think you have had a side effect, you can report it through the MHRA Yellow Card scheme.

Can it be used in pregnancy and breastfeeding?

The original content says Gaviscon Peppermint Liquid Relief is considered safe during pregnancy and breastfeeding. Heartburn and reflux are common during pregnancy, and this product is often used for symptom relief.

Even so, it is sensible to check with a healthcare professional if you are pregnant, breastfeeding, or unsure about any medicine you are using.

What about other medicines?

The original content notes that Gaviscon may affect the absorption of some medicines. It also says it should not be taken at the same time as other medicines, and a gap of at least two hours is recommended.

If you take regular medicines or supplements, ask a pharmacist or doctor how to space them safely.

When should you get advice?

Speak to a pharmacist or doctor if:

  • Your symptoms keep coming back
  • Your symptoms do not improve
  • You are unsure whether the product is suitable for you or a child
  • You take other medicines and need help with timing

Seek urgent medical help if symptoms are severe or if you are worried about a serious reaction.
