This medication may cause a condition known as tardive dyskinesia. In some cases, this condition may be permanent. Tardive dyskinesia is more likely to occur when metoclopramide is used for longer than 3 months, in high doses, or when used in the elderly (especially elderly women). Contact your doctor immediately if you develop any unusual uncontrolled movements (especially of the face, mouth, tongue, arms or legs). There is no treatment for tardive dyskinesia, but in some cases symptoms may lessen or stop once metoclopramide is stopped.

Because of the risk for tardive dyskinesia, metoclopramide should not be used for longer than 3 months (12 weeks), except in rare cases where the benefits of this drug outweigh the risk of developing tardive dyskinesia. Discuss the risks and benefits with your doctor.

Metoclopramide injection is used to prevent nausea and vomiting from surgery or cancer chemotherapy.

Metoclopramide is used to treat certain conditions of the stomach and intestines. Metoclopramide is used in diabetic patients who have poor emptying of their stomachs (gastroparesis). Treating gastroparesis can decrease symptoms of nausea, vomiting, and stomach/abdominal fullness. Metoclopramide is used as a short-term treatment (4 to 12 weeks). The injectable form of this medication should only be used when you cannot take the medication by mouth. Your doctor will switch you to the form taken by mouth as soon as you are able to take it.

Metoclopramide works by blocking a natural substance (dopamine). It speeds up stomach emptying and movement of the upper intestines.

Read the Medication Guide provided by your pharmacist before you start using metoclopramide and each time you get a refill. If you have any questions, consult your doctor or pharmacist.

This medication is given by injection into a muscle or vein by a health care professional. It is usually given as a single injection before your treatment/during surgery, or every 2 to 6 hours, or as directed by your doctor. If injecting into a vein, this medication must be given over at least 1 to 2 minutes to lower the risk of side effects such as anxiety, jitteriness, or drowsiness. It may also be mixed in a solution and given into a vein over 15 minutes or longer for higher doses.

Before using, check this product visually for particles or discoloration. If either is present, do not use the liquid.

Dosage and length of treatment is based on your weight, medical condition, and response to treatment.

The effects of some drugs can change if you take other drugs or herbal products at the same time. This can increase your risk for serious side effects or may cause your medications not to work correctly. These drug interactions are possible, but do not always occur. Your doctor or pharmacist can often prevent or manage interactions by changing how you use your medications or by close monitoring.

To help your doctor and pharmacist give you the best care, be sure to tell your doctor and pharmacist about all the products you use (including prescription drugs, nonprescription drugs, and herbal products) before starting treatment with this product. While using this product, do not start, stop, or change the dosage of any other medicines you are using without your doctor's approval.

Some products that may interact with this drug include: pramlintide, dopamine agonists (such as cabergoline, pergolide, ropinirole), tacrolimus, major tranquilizers (such as haloperidol, phenothiazines such as chlorpromazine, prochlorperazine), MAO inhibitors (isocarboxazid, linezolid, moclobemide, phenelzine, procarbazine, rasagiline, selegiline, tranylcypromine).

Some medications may block the actions of metoclopramide. Tell your doctor or pharmacist if you are also taking anticholinergic drugs (such as benztropine, scopolamine, antihistamines such as diphenhydramine) or narcotic pain/cough medications (such as codeine, morphine).

Since metoclopramide causes food and medication to move through your stomach more quickly, drugs that are absorbed from the stomach (such as digoxin) may not be absorbed as well. Drugs absorbed from the intestines (such as acetaminophen, levodopa, cyclosporine, alcohol, tetracycline) may have increased absorption.

Tell your doctor or pharmacist if you are taking other products that cause drowsiness, including alcohol, antihistamines (such as cetirizine, diphenhydramine), drugs for sleep or anxiety (such as alprazolam, diazepam, zolpidem), muscle relaxants, and narcotic pain relievers (such as codeine).

Check the labels on all your medicines (such as allergy or cough-and-cold products) because they may contain ingredients that cause drowsiness. Ask your pharmacist about using those products safely.

This document does not contain all possible interactions. Therefore, before using this product, tell your doctor or pharmacist of all the products you use. Keep a list of all your medications with you, and share the list with your doctor and pharmacist.
