DescriptionHistamine H 2
-receptor antagonists, also known as H 2
-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. H 2
-blockers
may also be used for other conditions as determined by your doctor.
