Motilium (domperidone) is a dopamine antagonist medication specifically formulated to address upper gastrointestinal motility issues. It is clinically indicated for the relief of symptoms such as nausea, vomiting, bloating, and feelings of fullness, often associated with delayed gastric emptying. By enhancing the coordinated contractions of the stomach and duodenum, it facilitates the normal passage of food, providing symptomatic relief and improving digestive comfort. This agent is a well-established option in the therapeutic management of functional dyspepsia and nausea of various etiologies.
Features
- Active Ingredient: Domperidone
- Pharmacological Class: Dopamine D2 and D3 receptor antagonist
- Primary Mechanism: Acts as a gastrokinetic and antiemetic agent
- Formulations: Typically available in 10 mg tablets and suspension forms
- Onset of Action: Symptomatic relief often begins within 30 to 60 minutes post-administration
- Prescription Status: Available by prescription in most jurisdictions
Benefits
- Effectively reduces episodes of nausea and vomiting by blocking dopamine receptors in the chemoreceptor trigger zone (CTZ)
- Accelerates gastric emptying and improves coordination of antroduodenal motility, alleviating postprandial fullness and bloating
- Provides targeted relief for symptoms of functional dyspepsia, improving overall quality of life
- May be used adjunctively in management of gastroesophageal reflux disease (GERD) symptoms when proton pump inhibitors are insufficient
- Lower incidence of extrapyramidal side effects compared to some other antiemetics due to poor blood-brain barrier penetration
- Available in multiple formulations to suit patient-specific needs, including pediatric suspensions
Common use
Motilium is commonly prescribed for the symptomatic management of nausea and vomiting, particularly when associated with delayed gastric emptying. It is utilized in cases of functional dyspepsia where patients experience early satiety, postprandial fullness, epigastric pain, or bloating. It is also employed off-label in some clinical settings to counteract nausea induced by other medications, such as dopamine agonists used in Parkinson’s disease. In lactation, it is sometimes used under medical supervision to augment milk supply, though this is not an approved indication in all regions.
Dosage and direction
The standard adult dosage for nausea and vomiting is 10 mg to 20 mg taken three to four times daily, preferably 15 to 30 minutes before meals and at bedtime. The maximum daily dose should not exceed 80 mg. For functional dyspepsia, 10 mg three times daily before meals is typical. Pediatric dosing is weight-based and must be carefully calculated by a healthcare provider; it is generally administered as 0.25 mg/kg to 0.5 mg/kg per dose, up to three times daily. Tablets should be swallowed whole with water; the oral suspension must be shaken well before use. Treatment duration should be the shortest necessary to control symptoms, and long-term use requires periodic reevaluation.
Precautions
Patients with pre-existing liver impairment should use Motilium with caution, as domperidone is metabolized hepatically. Electrolyte disturbances (e.g., hypokalemia, hypomagnesemia) may increase the risk of arrhythmias and should be corrected prior to initiation. Use with caution in patients with underlying cardiac conditions or those taking other QT-prolonging drugs. Elderly patients may be more susceptible to adverse effects and often require dose adjustment. Motilium should not be used concomitantly with certain antifungals or antibiotics that inhibit CYP3A4. Patients should be advised to report symptoms such as palpitations, syncope, or irregular heartbeat immediately.
Contraindications
Motilium is contraindicated in patients with known hypersensitivity to domperidone or any excipients in the formulation. It must not be used in individuals with pre-existing prolongation of cardiac conduction intervals, particularly QTc, or in those with significant electrolyte disturbances. Severe hepatic impairment is a contraindication. Concomitant use with potent CYP3A4 inhibitors (e.g., ketoconazole, erythromycin) is prohibited. It is also contraindicated in patients with prolactinoma or known mechanical gastrointestinal obstruction, perforation, or hemorrhage.
Possible side effect
Common adverse reactions include dry mouth, headache, and abdominal cramps. Less frequently, patients may experience nervousness, drowsiness, or diarrhea. Domperidone can elevate prolactin levels, leading to galactorrhea, gynecomastia, or menstrual irregularities. Although rare, serious side effects include QT interval prolongation and associated ventricular arrhythmias, such as torsades de pointes. Allergic reactions, including rash and pruritus, may occur. Any signs of cardiac arrhythmia require immediate discontinuation and medical attention.
Drug interaction
Domperidone is primarily metabolized by CYP3A4; concomitant use with strong inhibitors of this enzyme (e.g., ketoconazole, fluconazole, clarithromycin) significantly increases plasma levels and the risk of QT prolongation. Use with other drugs that prolong the QT interval (e.g., certain antipsychotics, antiarrhythmics) is not recommended. Anticholinergic agents may antagonize the prokinetic effects of domperidone. Caution is advised when combining with dopamine agonists or antagonists due to potential opposing effects on dopaminergic pathways.
Missed dose
If a dose is missed, it should be taken as soon as remembered, unless it is nearly time for the next scheduled dose. In that case, the missed dose should be skipped, and the regular dosing schedule resumed. Doubling the dose to make up for a missed one is not recommended.
Overdose
Symptoms of overdose may include agitation, confusion, seizures, and extrapyramidal reactions, although these are uncommon due to limited central penetration. Cardiac effects, including QT prolongation and arrhythmias, are of greatest concern. Management is supportive and symptomatic; gastric lavage may be considered if ingestion was recent. Activated charcoal can be administered. ECG monitoring is essential. There is no specific antidote.
Storage
Store at room temperature (15–30°C), in a dry place, protected from light and moisture. Keep out of reach of children and pets. Do not use after the expiration date printed on the packaging. For suspension, discard any unused portion after the recommended period (usually 14 days after opening).
Disclaimer
This information is for educational purposes only and does not constitute medical advice.

Do not self-medicate or alter your treatment regimen without consulting your doctor. Individual response to medication may vary.
Reviews
Clinical studies and meta-analyses have demonstrated the efficacy of domperidone in reducing symptoms of nausea, vomiting, and functional dyspepsia. It is generally well-tolerated, with a favorable side effect profile when used appropriately and at recommended doses. However, regulatory agencies in several countries have issued warnings regarding its potential to cause serious cardiac adverse events, particularly at high doses or in susceptible populations. Long-term safety data are limited, and it is recommended for short-term use only. Patient-reported outcomes often indicate significant improvement in gastrointestinal symptoms and quality of life.
