As of 2015, antacids in the United States containing magnesium trisilicate include Gaviscon-2, Gaviscon regular strength tablets, Acid Gone, Alenic Alka tablets and Genaton chewables, according to Drugs.com. Magnesium trisilicate is also used as a food additive.
Magnesium trisilicate relieves symptoms of indigestion and heartburn by neutralizing the acid naturally produced by the stomach, as stated by Patient.co.uk. Individuals should take a magnesium trisilicate antacid between meals and before bedtime unless otherwise instructed by a doctor, and they should not take it within 2 hours before or after taking other medications as it may affect absorption. The medication should be stored in a cool, dry area away from direct sunlight and out of reach of children.
Side effects of magnesium trisilicate medications include stomach cramps, mild diarrhea and gas, as listed by Patient.co.uk. Individuals should speak with a doctor before taking magnesium trisilicate antacids if they are pregnant, have liver or kidney problems, are on a low-sodium diet, are allergic to any type of medicine or have low levels of phosphate in their blood. Like all antacids, magnesium trisilicate medications work best if taken when symptoms occur or before they are expected to occur. Individuals should not take them daily unless instructed by a doctor.
