Tardive Dyskinesia

• Metoclopramide can cause tardive dyskinesia, a serious movement disorder that is often irreversible. There is no known treatment for tardive dyskinesia. The risk of developing tardive dyskinesia increases with duration of treatment and total cumulative dose. 
• Discontinue metoclopramide in patients who develop signs or symptoms of tardive dyskinesia.  In some patients, symptoms may lessen or resolve after metoclopramide is stopped.
• Avoid treatment with metoclopramide for longer than 12 weeks because of the increased risk of developing tardive dyskinesia with long-term use.[1]
