Gaviscon Double Action Mint – 24 Chewable Tablets

Description

Gaviscon Double Action Mint – 24 Chewable Tablets

Gaviscon Double Action Mint Chewable Tablets are used to relieve the uncomfortable symptoms of heartburn, acid indigestion, and reflux. They are suitable for adults and children aged 12 and over, and come in a pleasant mint flavour.

⸻

How It Works

Gaviscon Double Action works in two ways to tackle heartburn and indigestion. The sodium alginate reacts with stomach acid to form a gel-like raft that floats on top of the stomach contents, helping to prevent acid from rising back up into the food pipe (oesophagus). At the same time, the calcium carbonate and sodium bicarbonate help to neutralise excess stomach acid, providing fast relief from discomfort.

Directions for Use

Adults and children aged 12 years and over should chew 2 to 4 tablets after meals and at bedtime, up to four times a day. Tablets should be chewed thoroughly before swallowing. Do not exceed 16 tablets in any 24-hour period. This medicine is not recommended for children under 12 years of age unless directed by a doctor. Always read the patient information leaflet before use. If you are unsure about the correct dose, speak to your PillSorted pharmacist.

Pregnancy and Breastfeeding

Gaviscon Double Action Mint Tablets are commonly used during pregnancy to relieve heartburn; however, each tablet contains sodium, so prolonged or high-dose use should be discussed with a healthcare professional. The medicine is generally considered compatible with breastfeeding, but as with all medicines, caution is advised. Speak to your doctor or PillSorted pharmacist before use if you are pregnant, trying to conceive, or breastfeeding.

Alcohol

There is no known direct interaction between Gaviscon Double Action and alcohol. However, alcohol can irritate the stomach lining and worsen symptoms of heartburn and acid reflux, so it is best to limit alcohol consumption while experiencing these symptoms.
