Life‐threatening tardive dyskinesia caused by metoclopramide

Abstract

A case of severe life‐threatening tardive dyskinesia resulting in esophageal and respiratory difficulties due to metoclopramide therapy is presented. A 66‐year‐old man with a primary diagnosis of clear cell carcinoma of the biliary duct was treated with metoclopramide for gastrointestinal symptons related to his chemotherapy regimen. The patients initially presented with tremor and rigidity in the upper extremities. On antiparkinsonian therapy, symptons progressed to hemiballism and involuntary movements of the face, mouth, and tongue, with respiratory and esophageal dyskinesia. Despite discontinuance of metoclopramide, severe tardive dyskinetic symptons resulted in placement of a gastrostomy tube to maintain nutritional support. This case along with other in the literature should emphasize the need for continuous reevaluation of metoclopramide during long‐term therapy, since serious side effects have been reported to occur.
