Approved Drug Label (PDF)

Boxed Warning

PLR conversion; newly added information as below:


  • Reglan can cause tardive dyskinesia (TD), a serious movement disorder that is often irreversible. There is no known treatment for TD. The risk of developing TD increases with duration of treatment and total cumulative dosage.

  • Discontinue Reglan in patients who develop signs or symptoms of TD. In some patients, symptoms may lessen or resolve after Reglan is stopped.

  • Avoid treatment with Reglan for longer than 12 weeks because of the increased risk of developing TD with longer-term use.

4 Contraindications

PLR conversion; revised as below:

  • In patients with a history of tardive dyskinesia (TD) or a dystonic reaction to metoclopramide.

  • When stimulation of gastrointestinal motility might be dangerous (e.g., in the presence of gastrointestinal hemorrhage, mechanical obstruction, or perforation).

  • In patients with pheochromocytoma or other catecholamine-releasing paragangliomas.

  • Reglan may cause a hypertensive/pheochromocytoma crisis, probably due to release of catecholamines from the tumor.

  • In patients with epilepsy. Reglan may increase the frequency and severity of seizures.

  • In patients with hypersensitivity to metoclopramide. Reactions have included laryngeal and glossal angioedema and bronchospasm.

5 Warnings and Precautions

PLR conversion; subsections as below – please refer to label for more information:

5.1 Tardive Dyskinesia

5.2 Other Extrapyramidal Symptoms

5.3 Neuroleptic Malignant Syndrome

5.4 Depression

5.5 Hypertension

5.6 Fluid Retention

5.7 Hyperprolactinemia

5.8 Effects pm the Ability to Drive and Operate Machinery

6 Adverse Reactions

PLR conversion; as below:

The following adverse reactions are described, or described in greater detail, in other sections of the labeling:

  • Tardive dyskinesia

  • Other extrapyramidal effects

  • Neuroleptic malignant syndrome

  • Depression

  • Hypertension

  • Fluid retention

  • Hyperprolactinemia

Effects on the ability to drive and operate machinery

The following adverse reactions have been identified from clinical studies or postmarketing reports of metoclopramide. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure.

The most common adverse reactions (in approximately 10% of patients receiving 10 mg of metoclopramide four times daily) were restlessness, drowsiness, fatigue, and lassitude. In general, the incidence of adverse reactions correlated with the dosage and duration of metoclopramide administration.

Adverse reactions, especially those involving the nervous system, occurred after stopping metoclopramide including dizziness, nervousness, and headaches.

Central Nervous System Disorders

  • Tardive dyskinesia, acute dystonic reactions, drug-induced parkinsonism, akathisia, and other extrapyramidal symptoms

  • Convulsive seizures

  • Hallucinations

  • Restlessness, drowsiness, fatigue, and lassitude occurred in approximately 10% of patients who received 10 mg four times daily. Insomnia, headache, confusion, dizziness, or depression with suicidal ideation occurred less frequently.

  • Neuroleptic malignant syndrome, serotonin syndrome (in combination with serotonergic agents).

Endocrine Disorders: Fluid retention secondary to transient elevation of aldosterone. Galactorrhea, amenorrhea, gynecomastia, impotence secondary to hyperprolactinemia

Cardiovascular Disorders: Acute congestive heart failure, possible atrioventricular block, hypotension, hypertension, supraventricular tachycardia, bradycardia, fluid retention

Gastrointestinal Disorders: Nausea, bowel disturbances (primarily diarrhea)

Hepatic Disorders: Hepatotoxicity, characterized by, e.g., jaundice and altered liver function tests, when metoclopramide was administered with other drugs with known hepatotoxic potential.

Renal and Urinary Disorders: Urinary frequency, urinary incontinence

Hematologic Disorders: Agranulocytosis, neutropenia, leukopenia, methemoglobinemia, sulfhemoglobinemia

Hypersensitivity Reactions: Bronchospasm (especially in patients with a history of asthma), urticaria; rash; angioedema, including glossal or laryngeal edema

Eye Disorders: Visual disturbances

Metabolism Disorders: Porphyria

17 PCI/PI/MG (Patient Counseling Information/Patient Information/Medication Guide)


PLR conversion; newly added section, as below:

Advise the patient to read the FDA-approved patient labeling (Medication Guide).

Inform patients or their caregivers that Reglan can cause serious adverse reactions. Instruct patients to discontinue Reglan and contact a healthcare provider immediately if the following serious reactions occur:

  • Tardive dyskinesia and other extrapyramidal reactions
  • Neuroleptic malignant syndrome
  • Depression and/or possible suicidal ideation

Inform patients or their caregivers that concomitant treatment with numerous other medications can precipitate or worsen serious adverse reactions such as tardive dyskinesia or other extrapyramidal reactions, neuroleptic malignant syndrome, and CNS depression. Explain that the prescriber of any other medication must be made aware that the patient is taking Reglan.

Inform patients or their caregivers that Reglan can cause drowsiness or dizziness, or otherwise impair the mental and/or physical abilities required for the performance of hazardous tasks such as operating machinery or driving a motor vehicle.
