Safety Warnings For This Drug [top]

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]

Drugs used to treat cancer often cause severe nausea and vomiting, either immediately after the drug is taken or several hours later. You can treat this kind of nausea and vomiting by changing your diet or by taking an antinausea drug. You should always try dietary changes first.

  • Eat small, frequent meals so that your stomach is never empty.
  • When you get up from sleeping or resting, eat some dry crackers or toast before you start being active.
  • Drink carbonated drinks or other clear liquids such as soups and gelatin.
  • Eat tart foods such as lemons and pickles.
  • Do not eat foods with strong smells.

Facts About This Drug [top]

Metoclopramide (REGLAN) increases the tone of the muscle at the junction of the stomach and the esophagus (the tube connecting the mouth to the stomach) and increases stomach contractions. The drug relieves symptoms such as nausea, vomiting, loss of appetite, heartburn and a feeling of fullness after meals in people with diabetes who have a condition in which the stomach takes too long to empty (diabetic gastroparesis).

Metoclopramide (REGLAN) increases the tone of the muscle at the junction of the stomach and the esophagus (the tube connecting the mouth to the stomach) and increases stomach contractions. The drug relieves symptoms such as nausea, vomiting, loss of appetite, heartburn and a feeling of fullness after meals in people with diabetes who have a condition in which the stomach takes too long to empty (diabetic gastroparesis). The drug also controls reflux esophagitis, a condition in which the stomach contents flow backward into the esophagus, causing heartburn.

Patients over the age of 60 should generally be taking less than the usual adult dose, because older adults often do not tolerate metoclopramide well.

The use of metoclopramide tablets is recommended for adults only.[2]

This drug should not be used to treat motion sickness or vertigo (dizziness).


Metoclopramide is now one of a limited number of drugs for which the FDA requires an FDA-approved Medication Guide be dispensed when the prescription is filled. By clicking here, you can see the Medication Guide for metoclopramide. An FDA advisory committee has unanimously recommended that all prescription drugs be accompanied by such Medication Guides, but at present, less than 5 percent of drugs are. Unregulated, often dangerously incomplete information leaflets not approved by the FDA accompany the other 95 percent of drugs.

2011: Health Canada (an agency similar to the FDA in Canada) issued an advisory requiring stronger and more detailed warnings on the drug label of metoclopramide to include information on the risk of the neurological movement disorder tardive dyskinesia. Metoclopramide is not authorized in Canada for the following: treatment of hiccups, diabetic gastroparesis, nausea and vomiting in pregnancy, or bloating or constipation associated with eating disorders.[3]

2013: The European Medicines Agency’s Committee on Medicinal Products for Human Use informed the public that the agency was recommending changes on the use of products containing metoclopramide in the European Union. These changes include restrictions on the dose and the duration of therapy. The aim of the restrictions is to minimize the risks of already-known neurological side effects of metoclopramide.[4]

2015: Health Canada issued an advisory on the risk of extrapyramidal symptoms (symptoms of a drug-induced movement disorder, which includes tardive dyskinesia) in children taking metoclopramide. Health Canada advised that metoclopramide should never be used in children less than one year old and should not be used in children more than one year old unless the benefit is greater than the risk.[5]
