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 metoclopramide
Metoclopramide injection is a medicine that increases the movements or contractions of the stomach and intestines. It is used to help diagnose certain problems in the stomach or intestines. Metoclopramide is also used to prevent the nausea and vomiting that may occur after surgery or after treatment with cancer medicines. Another medicine may be used with metoclopramide injection to prevent side effects that may occur when it is used with cancer medicines.
Metoclopramide injection is also used to relieve symptoms (such as nausea, vomiting, heartburn, a feeling of fullness after meals, and loss of appetite) that are caused by a stomach problem called gastroparesis in patients with diabetes.
Metoclopramide is available only with your doctor's prescription.
Before using metoclopramide
In deciding to use a medicine, the risks of taking the medicine must be weighed against the good it will do. This is a decision you and your doctor will make. For metoclopramide, the following should be considered:
Tell your doctor if you have ever had any unusual or allergic reaction to metoclopramide or any other medicines. Also tell your health care professional if you have any other types of allergies, such as to foods, dyes, preservatives, or animals. For non-prescription products, read the label or package ingredients carefully.
Appropriate studies have not been performed on the relationship of age to the effects of metoclopramide injection in the pediatric population. Safety and efficacy have not been established.
Appropriate studies performed to date have not demonstrated geriatric-specific problems that would limit the usefulness of metoclopramide injection in the elderly. However, elderly patients are more likely to have side effects such as tardive dyskinesia, confusion, or drowsiness, and age-related kidney problems, which may require an adjustment in the dose for patients receiving metoclopramide injection.
There are no adequate studies in women for determining infant risk when using this medication during breastfeeding. Weigh the potential benefits against the potential risks before taking this medication while breastfeeding.

The following interactions have been selected on the basis of their potential significance and are not necessarily all-inclusive.

Proper use of metoclopramide
A nurse or other trained health professional will give you metoclopramide in a hospital. Metoclopramide is given through a needle placed in one of your veins or as a shot into one of your muscles.
Your doctor will give you a few doses of metoclopramide until your condition improves, and then switch you to an oral medicine that works the same way. If you have any concerns about this, talk to your doctor.
Precautions while using metoclopramide
It is very important that your doctor check your progress while you receive metoclopramide to make sure that it is working properly.
Tell your doctor or nurse right away if you have any of the following symptoms after receiving metoclopramide: convulsions (seizures); difficulty with breathing; a fast heartbeat; a high fever; high or low blood pressure; increased sweating; loss of bladder control; severe muscle stiffness; unusually pale skin; or tiredness. These could be symptoms of a serious condition called neuroleptic malignant syndrome (NMS).
Check with your doctor right away if you have any of the following symptoms: difficulty with speaking; drooling; loss of balance control; muscle trembling, jerking, or stiffness; restlessness; shuffling walk; stiffness of the limbs; twisting movements of the body; or uncontrolled movements of the face, neck, and back.
Metoclopramide may cause tardive dyskinesia (a movement disorder). Check with your doctor right away if you have any of the following symptoms while using metoclopramide: lip smacking or puckering, puffing of the cheeks, rapid or worm-like movements of the tongue, uncontrolled chewing movements, or uncontrolled movements of the arms and legs.
Metoclopramide may cause some people to become dizzy, lightheaded, drowsy, or less alert than they are normally. Make sure you know how you react to metoclopramide before you drive, use machines, or do anything else that could be dangerous if you are dizzy or not alert.
Metoclopramide will add to the effects of alcohol and other CNS depressants (medicines that make you drowsy or less alert). Some examples of CNS depressants are antihistamines or medicine for hay fever or colds; sedatives, tranquilizers, or sleeping medicine; prescription pain medicine or narcotics; medicine for seizures or barbiturates; muscle relaxants; or anesthetics, including some dental anesthetics. Check with your doctor before taking any of the above while you are using metoclopramide.
Do not take other medicines unless they have been discussed with your doctor. This includes prescription or nonprescription (over-the-counter [OTC]) medicines and herbal or vitamin supplements.
