Antacid pros & cons: Many antacids work by neutralizing acid in your stomach. Some contain simethicone that helps break up gas bubbles in your stomach. One floats on top of acid so it "coats" as the acid is refluxed. In any case, antacids must be taken multiple times a day to keep acid neutralized, and benefits are short-lived. Magnesium-containing ones can promote diarrhea; calcium-containing ones can increase acid!

Antacids : Some of the most common antacids are Mylanta, which is a combination of Aluminum hydroxide and magnesium hydroxide, Tums, which is calcium carbonate, milk of magnesia, which is magnesium hydroxide, and Maalox, which is calcium carbonate. There are also acid reducing medicines if regular antacids do not work.
