Key safety warnings

Tardive dyskinesia may appear in some patients on long-term therapy or after drug discontinuation. The risk appears greater in elderly patients on high dose therapy, especially females, and the symptoms can appear irreversible. One published study reported a tardive dyskinesia prevalence of 20% among patients treated for at least 3 months. Both the risk of developing the syndrome and the likelihood that it will become irreversible are believed to increase with duration of treatment and total cumulative dose. Prolonged treatment (greater than 12 weeks) with metoclopramide should be avoided in all but rare cases where therapeutic benefit is thought to outweigh the risks of developing tardive dyskinesia. Dystonic reactions occur in approximately 1% of patients given metoclopramide hydrochloride. These occur more frequently in children and young adults and may occur after a single dose. Very rare occurrences of Neuroleptic Malignant Syndrome have been reported. This syndrome is potentially fatal and comprises hyperpyrexia, altered consciousness, muscle rigidity, autonomic instability and elevated levels of CPK. Metoclopramide-induced depression has been reported in patients without a prior history of depression. Metoclopramide should be given to patients with a prior history of depression only if the expected benefits outweigh the potential risks. The most frequent adverse reactions are restlessness, drowsiness, fatigue, and lassitude, which occur in approximately 10% of patients. Less frequently, insomnia, headache, dizziness, nausea, or bowel disturbances may occur.

Contraindications

Metoclopramide should not be used whenever stimulation of gastrointestinal motility might be dangerous, such as in the presence of gastrointestinal haemorrhage, mechanical obstruction, or perforation. It should not be used in phaeochromocytoma because the drug may cause a hypertensive crisis. It is contraindicated in known hypersensitivity or intolerance to the drug. Metoclopramide should not be used in porphyria. It is contraindicated in epilepsy as metoclopramide may increase the frequency and severity of seizures. Metoclopramide tablets should not be used in children below 15 years of age.
