Antacid medicines

Names of antacid medicines

Antacid medicines are available in the form of both chewable tablets and liquids.

Examples of antacids include:

  • aluminium hydroxide
  • magnesium carbonate
  • magnesium hydroxide
  • magnesium trisilicate

As well as being used on their own, antacids can be combined with medicines such as simeticone and alignates.

Antacids and simeticone

Some antacids contain an added ingredient called simeticone. This combination helps relieve the symptom of flatulence (wind).

Antacids and alignates

Antacid medicines can also contain another group of medicines, called alignates. Alignates form a protective layer on the surface of your stomach which prevents acid flowing into your oesophagus (gullet).

Sodium alginate is found in most medicines that are used to treat indigestion and gastro-oesophageal reflux disease (GORD).
