How does this medication work? What will it do for me?
Metoclopramide belongs to the classes of medications called antiemetics and prokinetics. It is used to improve stomach emptying after surgery or other procedures. It can also be used to prevent nausea caused by narcotics after operations. It works by speeding up the rate at which the stomach empties and by blocking nausea triggers in the brain.
This medication may be available under multiple brand names and/or in several different forms. Any specific brand name of this medication may not be available in all of the forms or approved for all of the conditions discussed here. As well, some forms of this medication may not be used for all of the conditions discussed here.

How should I use this medication?
The recommended adult dose of metoclopramide for symptoms resulting from delayed stomach emptying ranges from 5 mg to 10 mg 3 or 4 times daily before meals. The recommended dose for children (aged 5 to 14 years) is 2.5 mg to 5 mg 3 times daily before meals. The injectable form of metoclopramide is most often used for the prevention of nausea and vomiting caused by chemotherapy. It is usually given by a health care professional in a hospital. The maximum daily dose for both adults and children is 0.5 mg/kg of body weight.
Swallow the tablets whole with a glass of water. Use an oral syringe to measure each dose of the liquid, as it gives a more accurate measurement than household teaspoons.

Are there any other precautions or warnings for this medication?
Before you begin using a medication, be sure to inform your doctor of any medical conditions or allergies you may have, any medications you are taking, whether you are pregnant or breast-feeding, and any other significant facts about your health. These factors may affect how you should use this medication.
Depression: Metoclopramide has been known to cause mood swings and symptoms of depression. If you have depression or a history of depression, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed. If you experience symptoms of depression such as poor concentration, changes in weight, changes in sleep, decreased interest in activities, or notice them in a family member who is taking this medication, contact your doctor as soon as possible.
Drowsiness/reduced alertness: Metoclopramide may cause drowsiness and increase the drowsiness caused by alcohol and other drugs. Avoid driving and doing other potentially hazardous activities until you have determined the effect this medication has on you.
Kidney function: People who have reduced kidney function may be at an increased risk of developing kidney failure. If you have reduced kidney function or kidney disease, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
Liver function: Liver disease or reduced liver function may cause this medication to build up in the body, causing side effects. If you have liver problems, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed. Your doctor may want to test your liver function regularly with blood tests while you are taking this medication.
Medical conditions: If you have epilepsy, Parkinson’s disease, or kidney disease, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
Neuroleptic malignant syndrome (NMS): In rare cases, metoclopramide can cause a potentially fatal syndrome known as neuroleptic malignant syndrome (NMS). If you notice the symptoms of NMS such as high fever, muscle stiffness, confusion or loss of consciousness, sweating, racing or irregular heartbeat, or fainting, get immediate medical attention.
Parkinson’s disease: Metoclopramide may worsen movement difficulties for people with Parkinson’s Disease. If you have Parkinson’s disease, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
Tardive dyskinesia (TD): Metoclopramide may cause tardive dyskinesia (TD) to develop. TD is a potentially irreversible syndrome of involuntary, repetitive movements of the face and tongue muscles. Although TD appears most commonly in seniors, especially women, it is impossible to predict who will develop TD. The risk of developing TD increases with higher doses and long-term treatment. If you experience muscle twitching or abnormal movements of the face or tongue, contact your doctor as soon as possible.
Seizures: Taking metoclopramide may increase the risk of experiencing movement disorders or more seizures. If you have a history of seizures or epilepsy, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
Pregnancy: This medication should not be used during pregnancy unless the benefits outweigh the risks. If you become pregnant while taking this medication, contact your doctor immediately.

Children: Metoclopramide should not be used in children less than one year of age. It should only be used in children over one year of age when the benefits of treatment outweigh the risks of side effects. Children may be more at risk of experiencing abnormal involuntary movements such as tremors and abnormal twitching movements, even at recommended dosages.
Seniors: Seniors appear to have a higher risk of side effects with long-term treatment of metoclopramide.
