DOSAGE AND ADMINISTRATION
DOSAGE AND ADMINISTRATION
For the Relief of Symptoms Associated with Diabetic Gastroparesis (Diabetic Gastric Stasis)
If only the earliest manifestations of diabetic gastric stasis are present, oral administration of metoclopramide may be initiated. However, if severe symptoms are present, therapy should begin with metoclopramide injection (IM or IV). Doses of 10 mg may be administered slowly by the intravenous route over a 1 to 2 minute period.
Administration of Metoclopramide Injection, USP up to 10 days may be required before symptoms subside, at which time oral administration of metoclopramide may be instituted. The physician should make a thorough assessment of the risks and benefits prior to prescribing further metoclopramide treatment.
For the Prevention of Nausea and Vomiting Associated with Emetogenic Cancer Chemotherapy
Intravenous infusions should be made slowly over a period of not less than 15 minutes, 30 minutes before beginning cancer chemotherapy and repeated every 2 hours for two doses, then every 3 hours for three doses.
The initial two doses should be 2 mg/kg if highly emetogenic drugs such as cisplatin or dacarbazine are used alone or in combination. For less emetogenic regimens, 1 mg/kg per dose may be adequate.
For doses in excess of 10 mg, Metoclopramide Injection, USP should be diluted in 50 mL of a parenteral solution.
The preferred parenteral solution is Sodium Chloride Injection (normal saline), which when combined with Metoclopramide Injection, USP, can be stored frozen for up to 4 weeks. Metoclopramide Injection, USP is degraded when admixed and frozen with Dextrose-5% in Water. Metoclopramide Injection, USP diluted in Sodium Chloride Injection, Dextrose-5% in Water, Dextrose-5% in 0.45% Sodium Chloride, Ringer's Injection, or Lactated Ringer's Injection may be stored up to 48 hours (without freezing) after preparation if protected from light. All dilutions may be stored unprotected from light under normal light conditions up to 24 hours after preparation.
If acute dystonic reactions should occur, inject 50 mg Benadryl® (diphenhydramine hydrochloride) intramuscularly, and the symptoms usually will subside.
For the Prevention of Postoperative Nausea and Vomiting
Metoclopramide Injection, USP should be given intramuscularly near the end of surgery. The usual adult dose is 10 mg; however, doses of 20 mg may be used.
To Facilitate Small Bowel Intubation
If the tube has not passed the pylorus with conventional maneuvers in 10 minutes, a single dose (undiluted) may be administered slowly by the intravenous route over a 1 to 2 minute period.
The recommended single dose is: Pediatric patients above 14 years of age and adults – 10 mg metoclopramide base. Pediatric patients (6 to 14 years of age) – 2.5 to 5 mg metoclopramide base; (under 6 years of age) – 0.1 mg/kg metoclopramide base.
To Aid in Radiological Examinations
In patients where delayed gastric emptying interferes with radiological examination of the stomach and/or small intestine, a single dose may be administered slowly by the intravenous route over a 1 to 2 minute period.
For dosage, see intubation, above.
Use in Patients with Renal or Hepatic Impairment
Since metoclopramide is excreted principally through the kidneys, in those patients whose creatinine clearance is below 40 mL/min, therapy should be initiated at approximately one-half the recommended dosage. Depending upon clinical efficacy and safety considerations, the dosage may be increased or decreased as appropriate.
See OVERDOSAGE section for information regarding dialysis.
Metoclopramide undergoes minimal hepatic metabolism, except for simple conjugation. Its safe use has been described in patients with advanced liver disease whose renal function was normal.
NOTE: Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration whenever solution and container permit.

MEDICATION GUIDE
MEDICATION GUIDE
Metoclopramide (met” oh kloe’ pra mide) Injection, USP
You or your caregiver should read the Medication Guide before you start receiving metoclopramide injection and before you get another dose of metoclopramide injection. There may be new information. If you take another product that contains metoclopramide (such as metoclopramide tablets, metoclopramide orally disintegrating tablets, or metoclopramide oral solution), you should read the Medication Guide that comes with that product. Some of the information may be different. This Medication Guide does not take the place of talking to your doctor about your medical condition or your treatment.
What is the most important information I should know about metoclopramide?
Metoclopramide can cause serious side effects, including:
Abnormal muscle movements called tardive dyskinesia (TD). These movements happen mostly in the face muscles. You can not control these movements. They may not go away even after stopping metoclopramide. There is no treatment for TD, but symptoms may lessen or go away over time after you stop taking metoclopramide.
Your chances for getting TD go up:
- •
- the longer you take metoclopramide and the more metoclopramide you take. You should not take metoclopramide for more than 12 weeks.
- •
- if you are older, especially if you are a woman
- •
- if you have diabetes
It is not possible for your doctor to know if you will get TD if you take metoclopramide.
Call your doctor right away if you get movements you can not stop or control, such as:
- •
- lip smacking, chewing, or puckering up your mouth
- •
- frowning or scowling
- •
- sticking out your tongue
- •
- blinking and moving your eyes
- •
- shaking of your arms and legs
See the section "What are the possible side effects of metoclopramide?" for more information about side effects.
