Liquid antacids are a type of medication used to neutralise stomach acid and provide relief from symptoms such as heartburn, indigestion, and acid reflux. These antacids come in a liquid form and are typically taken orally. They work by reacting with the acid in the stomach, reducing its acidity level and providing fast relief from discomfort. Liquid antacids are available in a variety of flavours and can be purchased over-the-counter from pharmacies and supermarkets. They are a popular choice for those looking for quick and effective relief from digestive issues.
