A household must-have, antacids help relieve nausea and heartburn caused by acid reflux in the stomach. Although many more brands are available on the market, popular antacid brands include Tums, Pepto Bismol, and Alka-Seltzer. All antacids contain the same kind of ingredients, each of which is a chemical compound that can temporarily relieve symptoms of acid reflux. Common compounds to look for include sodium bicarbonate, calcium carbonate, and aluminum hydroxide. Antacids are meant to be a temporary solution and do not stop acid reflux from happening. Speak with a doctor if you find yourself regularly taking antacids.
