Tagamet is a stomach acid reducer medication used to treat and prevent types of stomach ulcers. The medication is also used to treat gastroesophageal reflux disease (GERD).

Cimetidine is a histamine H2-receptor antagonist that reduces your body’s production of stomach acid through inhibitory actions. This allows Tagamet to treat and prevent stomach ulcers that form due to excess gastric acid as well as GERD which occurs when acid backs up into the esophagus.

This stomach acid medication is an effective treatment for stomach ulcers and GERD with minimal side effects. Tagamet has been proven to be more potent than other histamine H2 receptors without upsetting your other systems.
