General outline alongside the method by which it operates
Active substance: domperidone, commonly marketed as Motilium among other brands. It is used to help the upper digestive tract move more efficiently and to relieve nausea and vomiting. In UK practice the common tablet dose is 10 mg.
Domperidone blocks dopamine D2 and D3 receptors mainly outside the central nervous system. Because it penetrates the brain to a limited extent, it tends to cause fewer central nervous system possible side effects than some other antiemetics, though prescribers watch for cardiac rhythm effects that have been linked to the drug.

Signposts and clinical application
In the United Kingdom domperidone is generally prescribed for short-term management of nausea and vomiting. Its licensed use concentrates on these symptoms, but clinicians may also prescribe it when delayed gastric emptying appears to be contributing to symptoms.
Examples of situations where domperidone might be considered include:
- Short-term relief of nausea and vomiting from various causes.
- Supporting tolerance to other forms of therapy, for instance some chemotherapy protocols, under specialist supervision.
- Improving upper gastrointestinal motility when this is judged likely to reduce discomfort.
- As an adjunct for specific diagnostic or therapeutic procedures of the upper gut where increased motility is required, on specialist instruction.
Always follow the instructions from your prescriber. For specific dosing and administration guidelines see methods for taking and dosing..
How to take care of yourself and set the dose according to directions
Take domperidone exactly as your doctor or pharmacist instructs. Tablets are usually taken shortly before meals to maximise effect.
Adults and adolescents
For patients aged 12 years and older who weigh more than 35 kg:
- Common regimen: 10 mg up to three times each day, given before food.
- Maximum daily dose commonly recommended: 30 mg.
- For acute symptoms the usual short course is up to 7 days unless otherwise directed.
The kid crowd and special populations
Tablets are not recommended for children under 12 years or under 35 kg except on specialist advice. Liquid preparations, if used, require specialist dose optimization directional support.
Renal and hepatic considerations
- Severe renal impairment: drug elimination may be prolonged together with the prescriber may reduce dose or dosing frequency; long-term treatment should be reviewed.
- Moderate or severe hepatic impairment: domperidone should not be used.
Missed medication dose
If, by mistake, you forget a dose, take it when you remember unless it is nearly time for your next dose. Do not double up doses to make up a missed one.
Excipients and product notes
Some formulations contain lactose. If you have lactose intolerance, glucose-galactose malabsorption, or hereditary problems related to galactose, consult your pharmacist for a suitable a second option. See safety features and red flags against use of this medication to ensure added proactive precautions are in place.
Global archived data is kept in long term storage. optimization tips
- Store at a temperature between 20 and 25 C (68 and 77 F) unless the patient leaflet specifies otherwise.
- Keep away from excessive heat, moisture and direct light.
- Keep medications in their original packaging and out of the reach of children and pets.
- Avoid storing in bathrooms or other high humidity areas.
Safety protocols and health conditions that forbid use
Do not take domperidone if any of the following apply:
- Known allergy to domperidone or any ingredient of the product.
- Moderate or severe liver disease.
- Known or suspected prolonged QT interval, serious heart disease, or a history of ventricular arrhythmia.
- Concurrent use of medicines that strongly prolong QT or strong CYP3A4 inhibitors (see medication potential hazards in people relating to one another).
- Conditions where increased gut motility could be harmful, such as active gastrointestinal bleeding, perforation, or mechanical obstruction.
- Known prolactinoma or other pituitary tumor secreting prolactin.
Take extra care if you have low potassium or magnesium, significant kidney impairment, or other risk factors for arrhythmia. Seek urgent help for fainting, sudden severe dizziness, or palpitations.
Adverse medicines engagement and communication concerns
Many medicines can alter domperidone levels or increase cardiac risk. Tell your clinician about all prescribed medicines, over-the-counter products and herbal supplements.
Medicines that may reduce its effect
- Antimuscarinic agents, for example hyoscine, procyclidine, tolterodine, oxybutynin, and propantheline, can slow gut movement and counteract domperidone.
- Strong opioid analgesics such as morphine and codeine can also reduce gastrointestinal motility.
Medicines that increase domperidone levels or cardiac risk
- Strong CYP3A4 inhibitors: some azole antifungals (ketoconazole, itraconazole), certain macrolides (erythromycin, clarithromycin), some HIV protease inhibitors, and some calcium channel blockers (verapamil, diltiazem).
- Drugs known to prolong the QT interval: select antiarrhythmics, some antipsychotics, some antidepressants and others listed in the product key information.
Additional items may exist beyond this list. Preliminary to starting any new medicinevalidate this. with your prescriber or pharmacist. Further reading safety for use and contraindication.
During pregnancy and while breastfeeding
- Pregnancy: available data are limited. Use only if the expected benefit justifies potential risk to the fetus and after discussion in liaison with your clinician.
- Breastfeeding: small amounts can pass into breast milk. Routine use to treat maternal nausea or to increase milk production is not routinely recommended in the UK because of cardiac safety concerns; if considered, it should be supervised by a specialist after other methods have been tried.
Tell your healthcare professional if you are pregnant, planning pregnancy, or breastfeeding. For general protective protocols see safety.
Unanticipated effects
Many people experience no major negative possible side effects. When possible side effects occur they are often mild. Contact medical services immediately if you experience symptoms suggesting a serious heart issue: fainting, sudden severe lightheadedness, or a fast irregular heartbeat.
Common or reported reactions
- Dry mouth, migraine like headache, abdominal cramps or diarrhoea.
- Raised prolactin levels which may rarely cause breast enlargement, unexpected lactation or menstrual changes.
Not commonly found and rare reactions
- Reduced sexual desire, particularly reported in men.
- Allergic skin reactions including hives.
- Movement disorders such as tremor, stiffness or involuntary movements (uncommon).
If you notice worrying effects, contact your healthcare provider. For the process of interaction information see the exchange that happens when people meet profiles for drugs.
Medicines with similar profiles and optional variant options
Which alternative is best depends on the cause of the nausea, other health problems and growing potential the back and forth between peoples in the user journey shape satisfaction.. Discuss options with your doctor or pharmacist. Typical substitute options include:
- Metoclopramide: an effective antiemetic and prokinetic but with higher risk of central nervous system lingering reactions and extrapyramidal reactions; usually for short courses.
- Prochlorperazine: available orally and as buccal preparations; used for migraine-related or vestibular nausea but can cause sedation or dystonic reactions.
- Cyclizine: used for motion sickness and postoperative nausea; commonly causes drowsiness.
- Ondansetron: a 5-HT3 antagonist used in chemotherapy and postoperative settings; may cause constipation and has a low risk of QT prolongation.
- Erythromycin (low dose, off-label): acts on motilin receptors and can promote gastric emptying but has significant pharmacodynamic drug interacting with others potential and may cause abdominal cramps.
A pharmacist can help compare effectiveness, side effect profiles and cost. See a brief cost analysis for price comparison at prices charged in the UK.
