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

  • Tardive dyskinesia [see Boxed Warning and Warnings and Precautions (5.1)]
  • Other extrapyramidal effects [see Warnings and Precautions (5.2)]
  • Neuroleptic malignant syndrome [see Warnings and Precautions (5.3)]
  • Depression [see Warnings and Precautions (5.4)]
  • Hypertension [see Warnings and Precautions (5.5)]
  • Fluid retention [see Warnings and Precautions (5.6)]
  • Hyperprolactinemia [see Warnings and Precautions (5.7)]
  • Effects on the ability to drive and operate machinery [see Warnings and Precautions (5.8)]

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.
