H2 Blocker Uses
H2 Blockers for GERDGastroesophageal reflux disease (GERD) is caused by acid reflux into the esophagus. Acid reflux is a term referring to the backward flow of stomach acid into the esophagus. The stomach is designed to be able to handle the acid it produces; the esophagus, however, is not. If too much stomach acid is in contact with the esophagus for too long, damage to the lining of the esophagus occurs, causing the symptoms of GERD.

A few of the more common GERD symptoms include heartburn, feeling like food is stuck in your throat, choking feelings, acidic or sour taste in the mouth, and chest pain. All of the prescription H2 blockers are approved to treat the symptoms of GERD and esophagitis (damage to the esophagus) caused by GERD.
