Metoclopramide can cause tardive dyskinesia, a serious movement disorder that is often irreversible. 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. There is no known treatment for tardive dyskinesia. In some patients, symptoms may lessen or resolve after metoclopramide is stopped.

Metoclopramide treatment can cause tardive dyskinesia, a serious movement disorder that is often irreversible. Risk is increased with duration of treatment and total cumulative dose. Discontinue metoclopramide therapy in patients who develop signs or symptoms of tardive dyskinesia. There is no known treatment for tardive dyskinesia, although symptoms may lessen or resolve after metoclopramide discontinuation. Prolonged treatment with metoclopramide (greater than 12 weeks) should be avoided in all but rare cases where therapeutic benefit outweighs the risks .
Uses for Reglan
Metoclopramide is used to treat the symptoms of slow stomach emptying (gastroparesis) in patients with diabetes. It works by increasing the movements or contractions of the stomach and intestines. It relieves symptoms such as nausea, vomiting, heartburn, a feeling of fullness after meals, and loss of appetite. Metoclopramide is also used to treat heartburn for patients with gastroesophageal reflux disease (GERD). GERD is esophageal irritation from the backward flow of gastric acid into the esophagus.
This medicine is available only with your doctor's prescription.
