This is a combination antacid and anti-gas medicine. Aluminium hydroxide and magnesium hydroxide work together to neutralize excess stomach acid, while simeticone helps break up gas bubbles in your stomach and intestines so you feel less bloated.

For adults, take 1 to 2 chewable tablets or 10 to 20 ml of suspension, usually 20 to 60 minutes after meals and at bedtime, or whenever you feel heartburn or stomach discomfort. Chew the tablets well before swallowing — do not swallow them whole. Shake the suspension bottle well before each use. You can take it up to 4 times a day, but do not exceed the dose on the pack.
Since this medicine is usually taken only when you have symptoms (not on a fixed schedule), there is no real missed dose. Simply take it when you next feel heartburn, bloating, or stomach discomfort. Do not double up.
Buy only trusted brands like Dexanta, Gasmag, Gastacid, Avrocid, Digicid, or Ebecid from a registered pharmacy — avoid buying antacids from roadside sellers or open markets as they may be expired or fake. Do not use this medicine continuously for more than 2 weeks without seeing a doctor, as ongoing stomach pain could be a sign of something more serious. If you are taking other medicines, always space them out from this antacid by at least 2 hours.
This antacid can reduce the effectiveness of many other medicines if taken at the same time — especially antibiotics like ciprofloxacin and tetracycline, so take them at least 2 hours apart. It can also reduce the absorption of iron supplements and malaria drugs. Avoid taking it at the same time as any other oral medication; leave a gap of at least 1 to 2 hours.
