Tagamet (Cimetidine)

Tagamet is used for treating and preventing ulcers of the stomach and small intestine, and treating gastroesophageal reflux disease (GERD). It may be used for treating esophagitis (inflammation of the esophagus) caused by acid reflux and certain conditions that cause increased acid secretion (eg, Zollinger-Ellison syndrome). It may also be used to treat other conditions as determined by your doctor.

Use Tagamet as directed by your doctor. Check the label on the medicine for exact dosing instructions.
Take Tagamet by mouth with or without food.

If you also take cephalosporin (eg, cephalexin), itraconazole, or ketoconazole, take it at least 2 hours before taking Tagamet . Check with your doctor if you have questions.

Tagamet is an H2(histamine) blocker. It works by blocking one of the chemicals, histamine, that stimulates the release of acid into the stomach. This reduces acidity in the stomach.
