Hydrotalcite

How does it work?

Hydrotalcite suspension contains the active ingredient hydrotalcite (aluminium magnesium carbonate hydroxide hydrate).

Hydrotalcite is an antacid. It works by binding to excess acid in the stomach. This neutralises the acid and decreases the acidity of the stomach contents.

Antacids relieve the pain and discomfort of indigestion, heartburn and other symptoms related to excess stomach acid, by reducing the acidity of the stomach contents. They work as soon as they reach the stomach.

What is it used for?

Hydrotalcite suspension can be used to relieve symptoms of the following:

  • excess acid in the stomach (hyperacidity)
  • indigestion
  • heartburn, for example associated with oesophagitis, hiatus hernia or pregnancy
  • inflamed stomach lining (gastritis)
  • peptic ulcers.

How do I take it?

  • Shake the bottle before use.
  • Adults and adolescents over 12 years of age should take two 5ml spoonfuls (10ml) of hydrotalcite suspension between meals and at bedtime when needed to relieve symptoms.
  • Children aged 6 to 12 years can be given one 5ml spoonful of hydrotalcite suspension between meals and at bedtime when needed to relieve symptoms.
  • Do not exceed the recommended dose of this medicine.
