What is metoclopramide?

Metoclopramide increases muscle contractions in the upper digestive tract. This speeds up the rate at which the stomach empties into the intestines.

Metoclopramide oral (taken by mouth) is used for 4 to 12 weeks to treat heartburn caused by gastroesophageal reflux in people who have used other medications without relief.

Metoclopramide oral is also used to treat gastroparesis (slow stomach emptying) in people with diabetes, which can cause heartburn and stomach discomfort after meals.

Metoclopramide injection is used to treat severe diabetic gastroparesis. The injection is also used to prevent nausea and vomiting caused by chemotherapy or surgery, or to aid in certain medical procedures involving the stomach or intestines.

Warnings

Do not use this medicine if you've ever had muscle movement problems after using metoclopramide or similar medicines, or if you've had a movement disorder called tardive dyskinesia. You also should not use this medicine if you've had stomach or intestinal problems (a blockage, bleeding, or a hole or tear), epilepsy or other seizure disorder, or an adrenal gland tumor (pheochromocytoma).

NEVER USE METOCLOPRAMIDE IN LARGER AMOUNTS THAN RECOMMENDED, OR FOR LONGER THAN 12 WEEKS. High doses or long-term use can cause a serious movement disorder that may not be reversible. The longer you use metoclopramide, the more likely you are to develop this movement disorder. The risk of this side effect is higher in diabetics and older adults (especially women).

Before you take metoclopramide, tell your doctor if you have kidney or liver disease, congestive heart failure, high blood pressure, diabetes, Parkinson's disease, or a history of depression.

Do not drink alcohol. It can increase some of the side effects of metoclopramide.

Stop using metoclopramide and call your doctor at once if you have tremors or uncontrolled muscle movements, fever, stiff muscles, confusion, sweating, fast or uneven heartbeats, rapid breathing, depressed mood, thoughts of suicide or hurting yourself, hallucinations, anxiety, agitation, seizure, or jaundice (yellowing of your skin or eyes).

Before taking this medicine

You should not use metoclopramide if you are allergic to it, or if you have:

• tardive dyskinesia (a disorder of involuntary movements);

• stomach or intestinal problems such as a blockage, bleeding, or perforation (a hole or tear in your stomach or intestines);

• epilepsy or other seizure disorder;

• an adrenal gland tumor (pheochromocytoma); or

• if you've ever had muscle movement problems after using metoclopramide or similar medicines.

Tell your doctor if you have ever had:

• liver or kidney disease;

• problems with muscle movements;

• congestive heart failure or a heart rhythm disorder;

• high blood pressure;

• seizures;

• breast cancer;

• Parkinson's disease;

• diabetes; or

• depression or mental illness.

This medicine may contain phenylalanine. Check the medication label if you have phenylketonuria (PKU).

Tell your doctor if you are pregnant. Metoclopramide may harm an unborn baby if you use the medicine during late pregnancy.

It may not be safe to breast-feed a baby while you are using this medicine. Ask your doctor about any risks.

Metoclopramide is not approved for use by anyone younger than 18 years old.

How should I use metoclopramide?

Take metoclopramide exactly as prescribed by your doctor. Follow the directions on your prescription label and read all medication guides. Use the medicine exactly as directed.

A metoclopramide injection is given into a muscle or as an infusion into a vein. A healthcare provider will give the injection, usually during surgery, chemotherapy, or a medical procedure.

Metoclopramide oral is taken for only 4 to 12 weeks.

NEVER USE METOCLOPRAMIDE IN LARGER AMOUNTS THAN RECOMMENDED, OR FOR LONGER THAN 12 WEEKS. High doses or long-term use of metoclopramide can cause a serious movement disorder that may not be reversible. The longer you use metoclopramide, the more likely you are to develop this movement disorder. The risk of this side effect is higher in diabetics and older adults (especially women).

Metoclopramide is usually taken 30 minutes before meals and at bedtime, or only with meals that usually cause heartburn. Follow your doctor's dosing instructions very carefully.

Do not use two different forms of metoclopramide (such as tablets and oral syrup) at the same time.

Measure liquid medicine carefully. Use the dosing syringe provided, or use a medicine dose-measuring device (not a kitchen spoon).

To take the orally disintegrating tablet (ODT):

• Remove a tablet from its blister pack only when you are ready to take the tablet. Use dry hands and take care not to damage a tablet while pushing it out of the blister.

• Place the tablet in your mouth and allow it to dissolve, without chewing or swallowing it whole. You may sip liquid if needed to help swallow the dissolved tablet.

Store at room temperature in a tightly-closed container, away from moisture and heat. Keep the bottle tightly closed.

After you stop taking metoclopramide, you may have unpleasant withdrawal symptoms such as headache, dizziness, or nervousness.

Dosing information

Usual Adult Dose for Nausea/Vomiting:

Parenteral: 10 to 20 mg IM at or near the end of surgery

Usual Adult Dose for Gastroesophageal Reflux Disease:

Oral: 10 to 15 mg up to 4 times a day 30 minutes before meals and at bedtime, depending upon symptoms being treated and clinical response. Therapy should not exceed 12 weeks.

Usual Adult Dose for Gastroparesis:

During the earliest manifestations of diabetic gastric stasis, oral administration may be initiated. If severe symptoms are present, therapy should begin with IM or IV administration for up to 10 days until symptoms subside at which time the patient can be switched to oral therapy. Since diabetic gastric stasis is often recurrent, therapy should be reinstituted at the earliest manifestation.

Parenteral: 10 mg 4 times daily, IV (slowly over a 1 to 2 minute period) or IM for up to 10 days.

Oral: 10 mg 4 times daily, 30 minutes before meals and at bedtime, for 2 to 8 weeks depending on clinical response.

Usual Adult Dose for Nausea/Vomiting -- Chemotherapy Induced:

IV infusion: 1 to 2 mg/kg/dose (depending on the emetogenic potential of the agent) IV (infused over a period of not less than 15 minutes) 30 minutes before administration of chemotherapy. The dose may be repeated twice at 2 hour intervals following the initial dose. If vomiting is still not suppressed, the same dose may be repeated 3 more times at 3 hour intervals.

If acute dystonic reactions occur, 50 mg of diphenhydramine hydrochloride may be injected IM.
