GAVISCON PEPPERMINT LIQUID (SACHET) 10ML 5S

It contains sodium alginate, which is naturally derived. It is classed as an “alginate” which means that it forms a “protective layer” over the stomach contents which helps to prevent acid coming back up into the oesophagus (food pipe).
It is fast acting and has a soothing effect, lasting up to four hours.
It is effective at treating the classic symptoms of heartburn (a burning pain in the chest and mild acid regurgitation).
