Antacids are oral medications that lower acidity in the stomach. Most antacids are available over-the-counter without a prescription. They come in many different forms, including liquid, capsule, tablet and granule form. Antacids are used to treat a variety of gastrointestinal issues. Dosage often depends on what condition the antacids are treating. While considered safe, antacids may not be appropriate for those on a sodium restricted diet, those taking other medications, those with pre-existing medical conditions or those who are pregnant.
An antacid is a medication taken to reduce stomach acidity, typically to relieve pain from heartburn or indigestion. Antacids also help relieve the pain of stomach and duodenal ulcers. Available in various forms, antacids can be purchased without a prescription, but people are advised to talk with a physician about their use.
