Gaviscon Advance Mint – 24 Chewable Tablets

Description

Gaviscon Advance Mint – 24 Chewable Tablets

Gaviscon Advance Mint Chewable Tablets are used to relieve the symptoms of heartburn, acid reflux, and indigestion. They are suitable for adults and children aged 12 years and over.

⸻

How It Works

When chewed, these tablets release sodium alginate and potassium bicarbonate, which react with stomach acid to form a thick, gel-like raft that floats on top of the stomach contents. This raft acts as a physical barrier, helping to prevent acid from rising back up into the oesophagus (food pipe) and relieving the burning sensation associated with heartburn and acid reflux.

Directions for Use

Adults and children aged 12 years and over: Chew 2 to 4 tablets after meals and at bedtime, up to four times a day. Do not exceed 4 doses (16 tablets) in 24 hours. Swallow the chewed tablets — no water is needed, making them convenient to take on the go. Always read the patient information leaflet before use. If you are unsure about the correct dose, speak to your PillSorted pharmacist.
