Why is this medication prescribed?

Tagamet is the brand name for cimetidine, a medication that belongs to a class of drugs known as H2 blockers. It is primarily prescribed for the treatment of conditions related to excessive stomach acid production. The main uses of Tagamet include:

  • Peptic Ulcers: Tagamet is often prescribed to treat and prevent peptic ulcers (sores that develop on the lining of the stomach or small intestine).
  • Gastroesophageal Reflux Disease (GERD): It can be used to manage symptoms associated with GERD, such as heartburn and acid regurgitation.
  • Zollinger-Ellison Syndrome: This is a rare condition characterized by tumors in the pancreas or duodenum that cause overproduction of stomach acid. Tagamet may be used to reduce excessive acid in such cases.
  • Erosive Esophagitis: Tagamet can be part of the treatment plan for this condition, which involves inflammation and damage to the esophagus due to stomach acid.
  • Prevention of Aspiration Pneumonia: Tagamet may be used in some cases to reduce the risk of aspiration pneumonia in individuals at risk, as it can decrease stomach acid production.

Other uses for this medicine

Some off-label uses may include:
