title: Cimetidine-induced dystonic reaction.
abstract: A 39-year-old woman presented to the Emergency Department complaining of nausea and vomiting. The patient was given intravenous cimetidine for epigastric pain and subsequently developed a dystonic reaction. Administration of cimetidine, an H2 receptor antagonist, is an uncommon cause of dystonic reaction. We discuss the pathophysiology, diagnosis, and treatment.
