How does this medication work? What will it do for me?
Cimetidine is used to reduce the pain of ulcer and heartburn or to assist in the healing of ulcers and damage caused by gastroesophageal reflux disease (GERD).
Cimetidine is also used to prevent ulcers in certain circumstances and to treat certain conditions that are associated with oversecretion of acid by the stomach (i.e., Zollinger-Ellison Syndrome, systemic mastocytosis, and multiple endocrine adenomas). The medication works by reducing the amount of acid secreted by the stomach.
