Antacids are over-the-counter medications used to neutralize stomach acid and alleviate symptoms of heartburn, indigestion, and acid reflux. They come in various forms such as tablets, liquids, and chewable tablets. Antacids work by increasing the pH level in the stomach, reducing the amount of acid that can cause discomfort. They are a quick and effective way to relieve symptoms, but it is important to follow the advised dosage and speak to a healthcare professional if symptoms persist.
