USES: Cimetidine is used to treat ulcers of the stomach or intestines and prevent them from returning after treatment. This medication is also used to treat certain stomach and throat problems caused by too much acid (e.g., Zollinger-Ellison syndrome, erosive esophagitis) or a backward flow of stomach acid into the esophagus (gastroesophageal reflux disease-GERD).This form of cimetidine is given by injection and is used for short-term treatment of these conditions when you cannot take this medication by mouth. Your doctor should switch you to taking this medication by mouth when possible.Cimetidine injection is also used to prevent serious stomach bleeding in very ill patients (usually in the hospital/ICU).Cimetidine is known as an H2 histamine blocker. It works by reducing the amount of acid in your stomach. This effect helps heal and prevent ulcers and improves symptoms such as heartburn and stomach pain.
