Subject to body weight consideration, (see above)
In elderly patients a dose reduction should be considered, based on renal and
hepatic function and overall frailty.
In patients with end stage renal disease (Creatinine clearance ≤15 ml/min), the
daily dose should be reduced by 75%.
In patients with moderate to severe renal impairment (Creatinine clearance 1560ml/min), the dose should be reduced by 50% (see section 5.2).
In patients with severe hepatic impairment, the dose should be reduced by
50% (see section 5.2).
Metoclopramide is contraindicated in children aged less than 1 year (see section 4.3).
- Hypersensitivity to the active substance or to any of the excipients listed in
- Gastrointestinal haemorrhage, mechanical obstruction or gastro-intestinal
perforation for which the stimulation of gastrointestinal motility constitutes
- Confirmed or suspected pheochromocytoma, due to the risk of severe
- History of neuroleptic or metoclopramide-induced tardive dyskinesia
- Epilepsy (increased crises frequency and intensity)
- Parkinson’s disease
- Combination with levodopa or dopaminergic agonists (see section 4.5)
- Known history of methaemoglobinaemia with metoclopramide or of
NADH cytochrome-b5 deficiency.
- Use in children less than 1 year of age due to an increased risk of
extrapyramidal disorders (see section 4.4)
‘Maxolon’ should not be used during the first three to four days following
operations such as pyloroplasty or gut anastomosis as vigorous muscular
contractions may not help healing.
Special warnings and precautions for use
Extrapyramidal disorders may occur, particularly in children and young adults,
and/or when high doses are used. These reactions occur usually at the
beginning of the treatment and can occur after a single administration.
Metoclopramide should be discontinued immediately in the event of
extrapyramidal symptoms. These effects are generally completely reversible
after treatment discontinuation, but may require a symptomatic treatment
(benzodiazepines in children and/or anticholinergic anti-Parkinsonian
medicinal products in adults).
The time interval of at least 6 hours specified in the section 4.2 should be
respected between each metoclopramide administration, even in case of
vomiting and rejection of the dose, in order to avoid overdose.
Prolonged treatment with metoclopramide may cause tardive dyskinesia,
potentially irreversible, especially in the elderly. Treatment should not exceed
3 months because of the risk of tardive dyskinesia (see section 4.8). Treatment
must be discontinued if clinical signs of tardive dyskinesia appear.
Neuroleptic malignant syndrome has been reported with metoclopramide in
combination with neuroleptics as well as with metoclopramide monotherapy
(see section 4.8). Metoclopramide should be discontinued immediately in the
event of symptoms of neuroleptic malignant syndrome and appropriate
treatment should be initiated.
Special care should be exercised in patients with underlying neurological
conditions and in patients being treated with other centrally-acting drugs (see
Symptoms of Parkinson’s disease may also be exacerbated by
Methemoglobinemia which could be related to NADH cytochrome b5
reductase deficiency has been reported. In such cases, metoclopramide should
be immediately and permanently discontinued and appropriate measures
initiated (such as treatment with methylene blue).
There have been reports of serious cardiovascular undesirable effects
including cases of circulatory collapse, severe bradycardia, cardiac arrest and
QT prolongation following administration of metoclopramide by injection,
particularly via the intravenous route (see section 4.8).
Special care should be taken when administering metoclopramide, particularly
via the intravenous route to the elderly population, to patients with cardiac
conduction disturbances (including QT prolongation), patients with
uncorrected electrolyte imbalance, bradycardia and those taking other drugs
known to prolong QT interval.
Intravenous doses should be administered as a slow bolus (at least over 3
minutes) in order to reduce the risk of adverse effects (e.g. hypotension,
Renal and Hepatic Impairment
In patients with renal impairment or with severe hepatic impairment, a dose
reduction is recommended (see section 4.2).
Metoclopramide may cause elevation of serum prolactin levels.
Care should be exercised when using Maxolon in patients with a history of
atopy (including asthma) or porphyria.
Special care should be taken when administering Maxolon intravenously to
patients with “sick sinus syndrome” or other cardiac conduction disturbances.
Interaction with other medicinal products and other forms of interaction
Levodopa or dopaminergic agonists and metoclopramide have a mutual
antagonism (see section 4.3).
Combination to be avoided
Alcohol potentiates the sedative effect of metoclopramide.
Combination to be taken into account
Due to the prokinetic effect of metoclopramide, the absorption of certain drugs
may be modified.
Anticholinergics and morphine derivatives
Anticholinergics and morphine derivatives may have both a mutual
antagonism with metoclopramide on the digestive tract motility.
Central nervous system depressants (morphine derivatives, anxiolytics,
sedative H1 antihistamines, sedative antidepressants, barbiturates, clonidine
Sedative effects of Central Nervous System depressants and metoclopramide
Metoclopramide may have an additive effect with other neuroleptics on the
occurrence of extrapyramidal disorders.
The use of metoclopramide with serotonergic drugs such as SSRIs may
increase the risk of serotonin syndrome.
Metoclopramide may decrease digoxin bioavailability. Careful monitoring of
digoxin plasma concentration is required.
Metoclopramide increases cyclosporine bioavailability (Cmax by 46% and
exposure by 22%). Careful monitoring of cyclosporine plasma concentration is
required. The clinical consequence is uncertain.
Mivacurium and suxamethonium
Metoclopramide injection may prolong the duration of neuromuscular block
(through inhibition of plasma cholinesterase).
Strong CYP2D6 inhibitors
Metoclopramide exposure levels are increased when co-administered with
strong CYP2D6 inhibitors such as fluoxetine and paroxetine. Although the
clinical significance is uncertain, patients should be monitored for adverse
The effects of certain other drugs with potential central stimulant effects, e.g.
monoamine oxidase inhibitors and sympathomimetics, may be modified when
prescribed with metoclopramide and their dosage may need to be adjusted
‘Maxolon’ may reduce plasma concentrations of atovaquone.
Fertility, pregnancy and lactation
A large amount of data on pregnant women (more than 1000 exposed
outcomes) indicates no malformative toxicity, nor foetotoxicity.
Metoclopramide can be used during pregnancy if clinically needed. Due to
pharmacological properties (as other neuroleptics), in case of metoclopramide
administration at the end of pregnancy, extrapyramidal syndrome in newborn
cannot be excluded.
Metoclopramide should be avoided at the end of pregnancy.
metoclopramide is used, neonatal monitoring should be undertaken.
Metoclopramide is excreted in breast milk at low level. Adverse reactions in
the breast-fed baby cannot be excluded. Therefore metoclopramide is not
recommended during breastfeeding. Discontinuation of metoclopramide in
breastfeeding women should be considered.
Effects on ability to drive and use machines
Metoclopramide has moderate influence on the ability to drive and use
Metoclopramide may cause drowsiness, dizziness, dyskinesia and dystonias
which could affect the vision and also interfere with the ability to drive and

Reporting of suspected adverse reactions
Reporting suspected adverse reactions after authorisation of the medicinal product is
important. It allows continued monitoring of the benefit/risk balance of the medicinal
product. Healthcare professionals are asked to report any suspected adverse reactions
via the Yellow Card Scheme Website: www.mhra.gov.uk/yellowcard.
Extrapyramidal disorders, drowsiness, decreased level of consciousness,
confusion, hallucination, and cardio-respiratory arrest may occur.
In case of extrapyramidal symptoms related or not to overdose, the treatment
is only symptomatic (benzodiazepines in children and/or anticholinergic antiparkinsonian medicinal products in adults).
A symptomatic treatment and a continuous monitoring of the cardiovascular
and respiratory functions should be carried out according to clinical status.
Pharmacotherapeutic group: Agents stimulating gastro-intestinal motility
ATC code: A03FA01
The action of metoclopramide is closely associated with parasympathetic
nervous control of the upper gastro-intestinal tract, where it has the effect of
encouraging normal peristaltic action. This provides for a fundamental
approach to the control of those conditions where disturbed gastro-intestinal
motility is a common underlying factor.
Metoclopramide is metabolised in the liver and the predominant route of
elimination of metoclopramide and its metabolites is via the kidney.
The clearance of metoclopramide is reduced by up to 70% in patients with
severe renal impairment, while the plasma elimination half-life is increased
(approximately 10 hours for a creatinine clearance of 10-50 mL/minute and 15
hours for a creatinine clearance <10 mL/minute).
In patients with cirrhosis of the liver, accumulation of metoclopramide has
been observed, associated with a 50% reduction in plasma clearance.
