About Antacid Suspension (Aluminium Hydroxide + Magnesium Hydroxide + Simethicone)
Antacid Suspension (Aluminium Hydroxide + Magnesium Hydroxide + Simethicone) contains Aluminium Hydroxide + Magnesium Hydroxide + Simethicone. This is an antacid combination with an anti-gas ingredient. Aluminium hydroxide and magnesium hydroxide neutralise extra stomach acid, and simethicone helps break up gas bubbles. It is used for short-term relief of acidity, heartburn, indigestion and bloating.

Get medical help if you notice
- Black stools, vomiting blood or severe stomach pain — these need a doctor, not an antacid; seek medical help

How to use
Shake the bottle well before use. Take it as your doctor or the label advises, usually after meals and at bedtime, or when symptoms occur. Use the measuring cup provided. Do not use it for more than two weeks without asking a doctor.
How it works
Aluminium hydroxide and magnesium hydroxide are bases that react with stomach acid and neutralise it. Simethicone lowers the surface tension of gas bubbles so they join and are passed more easily.
