GERD Home > H2 Blockers
H2 blockers are medications that are used to treat conditions such as duodenal ulcers, gastric ulcers, and gastroesophageal reflux disease (GERD). Because they reduce the amount of acid in the stomach, they are also known as "acid reducers." They are taken by mouth, usually one to four times per day. A few of the most common side effects include abdominal pain (or stomach pain), constipation, and dizziness.
