The recommended dosage for Gaviscon tablets for adults and children aged 12 years and over is to take 2 to 4 chewable tablets after meals and at bedtime, up to four times a day. The tablets should be thoroughly chewed and not swallowed whole. The maximum daily amount of tablets you can take is generally up to 16 tablets per day (4 doses of 2 to 4 tablets each). If symptoms persist for more than 7 days, you should consult a doctor. Taking too many tablets may cause bloating but is unlikely to cause serious harm.

For children under 12 years, Gaviscon tablets should only be taken on medical advice.
