Gaviscon Advance Aniseed offers extra-strength protection against heartburn, indigestion, and acid reflux. Specially developed for long-lasting results, this liquid suspension forms a strong barrier to help stop stomach acid from travelling back into the oesophagus, easing discomfort and protecting your throat and chest from irritation.
Its smooth aniseed flavour provides a soothing taste alternative to peppermint, making it an ideal choice for those who prefer a milder, warming flavour profile.
Gaviscon Advance Aniseed can be used to treat and prevent:
The key active ingredients, sodium alginate and potassium bicarbonate, create a protective raft on top of your stomach contents, physically blocking acid from escaping into your oesophagus. At the same time, potassium bicarbonate neutralises excess acid for immediate soothing relief.
Gaviscon Advance Aniseed is suitable for most adults and children over 12 years of age. If you are on a controlled-sodium diet, have kidney problems, or are taking other medication, seek advice before use.
Take 5–10ml after meals and before bedtime, up to four times daily. Shake the bottle well before use and follow dosing instructions carefully.
