Histamine H2-receptor antagonists, also known as H2-blockers, are used to treat duodenal ulcers and prevent their return. They are also used to treat gastric ulcers and for some conditions, such as Zollinger-Ellison disease, in which the stomach produces too much acid. In over-the-counter (OTC) strengths, these medicines are used to relieve and/or prevent heartburn, acid indigestion, and sour stomach. H2-blockers may also be used for other conditions as determined by your doctor.
H2-blockers work by decreasing the amount of acid produced by the stomach.
H2-blockers are available both over-the-counter (OTC) and with your doctor's prescription.
Once a medicine has been approved for marketing for a certain use, experience may show that it is also useful for other medical problems. Although these uses are not included in product labeling, H2-blockers are used in certain patients with the following medical conditions:
- Damage to the stomach and/or intestines due to stress or trauma
- Pancreatic problems
- Stomach or intestinal ulcers (sores) resulting from damage caused by medication used to treat rheumatoid arthritis
