The 40mg tablet of Famonext is an antacid. It lessens the quantity of acid your stomach produces. It is used to prevent and treat indigestion, heartburn, and other symptoms brought on by an excess of stomach acid. 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 may be a sign of dyspepsia, or indigestion. Famonext 40mg Tablet is a member of the class of medications known as histamine 2 antagonists. It soothes the pain of indigestion and heartburn by decreasing the quantity of acid your stomach produces. For it to work, you must take it precisely as directed by your doctor or as indicated on the label. A few easy lifestyle adjustments can help prevent or lessen heartburn. Try to avoid the items that cause heartburn; eat smaller, more frequent meals; if you are overweight, try to reduce your weight; and find ways to unwind. Avoid eating three to four hours before bed.
