gastroesophageal reflux disease (GERD
Gastroesophageal reflux disease (GERD) or gastro-oesophageal reflux disease (GORD) is a chronic condition in which stomach contents and acid rise up into the esophagus, resulting in symptoms and/or complications.
The daily dose of famotidine will vary depending on the medical condition being treated. For gastroesophageal reflux disease (GERD), the maximum dose is 40 mg. per day. For esophagitis, the maximum dose is 80 mg.
In the management of GERD, famotidine is typically dosed as a 20 mg tablet taken twice per day. In more refractory cases, it is sometimes prescribed at the higher 40 mg dose. For GERD with evidence of erosive esophagitis, famotidine is typically dosed at 20 to 40 mg, in tablet form taken twice per day.
