Maalox plus suspension

How does it work?

Maalox plus suspension contains three active ingredients, aluminium hydroxide, magnesium hydroxide and simeticone.

Aluminium hydroxide and magnesium hydroxide are both medicines called antacids. They are used to reduce the acidity of the stomach's juices.

Stomach acid is produced in the stomach as a normal part of the digestive process. However, too much stomach acid can cause symptoms such as heartburn and indigestion. Antacids work by binding to and neutralising excess acid. This helps to relieve the symptoms of heartburn and indigestion associated with excess stomach acid.

Simeticone is sometimes called an anti-foaming agent or anti-flatulant. It is used to relieve pain and bloating caused by trapped wind. It works by bringing together all the small bubbles of gas to form a large bubble, which is then easily expelled by belching.

What is it used for?

  • Heartburn.
  • Upset stomach characterised by stomach pain and burning, nausea and excess gas (dyspepsia).
  • Excess gas in the stomach and intestines (flatulence or wind).
