An antacid is the Famonext 20 Tablet. It lessens the quantity of acid your stomach produces. It is used to treat and prevent heartburn, indigestion and other symptoms caused by too much acid in the stomach. Acid reflux is the process by which stomach acids return to your esophagus and mouth, causing heartburn, a burning sensation in your chest. It occurs when a muscle above your stomach relaxes excessively, allowing acid and stomach contents to reflux up into your mouth and esophagus. This can be a symptom of indigestion (dyspepsia). Famonext 20 Tablet belongs to a group of medicines called histamine 2 antagonists. It works by reducing the amount of acid your stomach makes and relieves the pain associated with heartburn and indigestion. You should take it exactly as it is prescribed or as it says on the label for it to be effective. A few easy lifestyle adjustments can help prevent or lessen heartburn. Think about what foods trigger heartburn and try to avoid them; eat smaller more frequent meals; try to lose weight if you are overweight and try to find ways to relax. Avoid eating three to four hours before bed.
