Motilium (Domperidone) — Patient Information (UK)
Motilium is a medicine containing domperidone. It is used to help relieve certain stomach and digestive symptoms, such as nausea (feeling sick), vomiting, and feeling overly full or uncomfortable after meals.
This page explains how Motilium works, how it is typically taken, common interactions, safety considerations, and what to expect in the UK. Always follow the instructions given by your healthcare professional or those on the product packaging.
1) Basic product information
- Active ingredient: Domperidone
- Brand: Motilium
- Common forms (availability varies): Tablets (e.g., film-coated) and oral formulations in some markets
- Therapeutic use: Anti-nausea / prokinetic (helps improve stomach movement)
- Regulatory status: In the UK, domperidone is a prescription-only medicine and use is subject to safety guidance
Note: Strengths and formulations may vary. Check the label/leaflet for your specific product and dose.
2) How Motilium works (mechanism of action)
Domperidone helps the digestive system by blocking dopamine (D2) receptors in the body. Dopamine can slow down stomach movement and influence nausea pathways.
By reducing dopamine’s effects, domperidone can:
- Improve gastric motility (movement of the stomach)
- Support better emptying from the stomach into the intestines
- Help reduce nausea and vomiting
- Reduce troublesome post-meal fullness in some people
Motilium does not “treat the cause” of all stomach problems, but it can relieve symptoms where delayed stomach emptying or dopamine-related nausea is involved.
3) Pharmacokinetics (how the body handles it)
Pharmacokinetics describes how the body absorbs, distributes, metabolises, and eliminates domperidone. Key points include:
- Absorption: Domperidone is absorbed after oral administration. Taking it at the right time can influence how quickly it starts to work.
- Distribution: It distributes throughout the body, including the digestive tract.
- Metabolism: Domperidone is metabolised mainly in the liver by enzymes (notably CYP3A4).
- Elimination: It is cleared from the body through metabolism and excretion.
- Heart-related considerations: Domperidone can affect the QT interval in some circumstances, which is why certain doses and interactions are restricted in the UK.
People with liver impairment may have altered drug levels and may not be suitable for use. Your clinician or pharmacist should advise based on your health status and other medicines.
4) What Motilium is typically used for (indications)
Motilium is used for symptoms such as:
- Nausea and vomiting (feeling sick and/or bringing up contents)
- Post-prandial fullness (feeling overly full quickly)
- Upper abdominal discomfort related to delayed stomach emptying
- Dyspepsia-like symptoms in some patients, particularly where the stomach empties slowly
The exact approved use and suitable patient groups depend on the UK product information for your formulation. If your symptoms are severe, persistent, or worsening, seek medical advice.
5) Typical timing: when to take Motilium
Timing can affect symptom relief. A common approach is to take domperidone:
- Before meals if your symptoms are mainly related to eating (e.g., fullness, nausea)
- Before bed if symptoms occur at night (only if advised)
Always follow the dose schedule on your packaging or the advice you were given. Do not exceed the recommended total daily dose.
6) Food interactions: effects of meals
Domperidone absorption can be influenced by food. In general:
- Taking it after food may slow the onset of effect in some people.
- Taking it before meals may help it start working sooner for meal-related symptoms.
If you notice your symptoms are not controlled, consider discussing timing adjustments with a healthcare professional or pharmacist.
7) Alcohol interactions
There is no specific “absolute” alcohol ban for everyone on Motilium, but alcohol may worsen stomach symptoms such as nausea, indigestion, and reflux—so you may feel less benefit from the medicine.
- Minimise alcohol if you have nausea, vomiting, or indigestion.
- If you choose to drink, consider taking Motilium with careful timing and monitor how you feel.
If you have liver disease or take multiple medicines, seek advice first.
8) Medicine interactions (important in the UK)
Domperidone has important interaction considerations, especially with medicines that can affect heart rhythm. In the UK, safety guidance is particularly strict regarding medicines that may increase the risk of an abnormal heart rhythm (QT prolongation).
8.1 Avoid strong CYP3A4 inhibitors
Domperidone is metabolised by CYP3A4. Medicines that strongly inhibit CYP3A4 can raise domperidone levels, increasing risk.
Examples (not exhaustive) of medicine classes commonly flagged include some:
- Antifungals (e.g., azole antifungals)
- Macrolide antibiotics (e.g., certain “-mycin” antibiotics)
- Some HIV antivirals
8.2 Medicines that can affect heart rhythm (QT interval)
Combining domperidone with other medicines that prolong the QT interval can raise the risk of potentially serious heart rhythm problems.
Examples include certain medicines for:
- Irregular heartbeat (antiarrhythmics)
- Some mental health conditions (some antipsychotics)
- Some antidepressants
- Certain antibiotics and antimalarials
- Some nausea medicines or migraine medicines that may influence QT (depends on the specific agent)
Always tell your pharmacist or clinician about all medicines you take, including:
- Over-the-counter medicines
- Herbal preparations
- Supplements (especially if they affect metabolism)
- New medicines started recently
8.3 Other practical interaction points
- Antacids or acid reducers: These may alter stomach conditions; they are not always a strict contraindication, but symptom response and timing may change.
- Apomorphine: There is a known interaction concern with domperidone in certain clinical settings—this is specialist-level guidance.
- Electrolyte issues: Low potassium or low magnesium can increase risk of QT-related problems. Vomiting/diarrhoea, certain diuretics, and other conditions can contribute.
If you are pregnant, have heart disease, or have a history of rhythm problems, it is essential to get personalised advice.
9) Dosing: how much to take and how often
Dosing depends on age, indication, and local product guidance. For safety in the UK, the dose limits and duration of use are important.
Always check your specific product packaging leaflet for the exact dose and maximum daily amount.
9.1 Adults (general typical approach)
Common regimens are taken in divided doses (multiple times daily) and often on an as-needed basis for symptom control rather than long-term continuous use.
9.2 Children
Domperidone may be used for specific paediatric indications, but dosing is weight- and age-dependent and should be determined by healthcare professionals. Children are more sensitive to some side effects, and UK safety guidance is strict.
9.3 Missed dose
- Take the next dose at the usual time.
- Do not take a double dose to make up for a missed dose.
9.4 Overdose
If more than the prescribed amount is taken, seek urgent medical advice—particularly because of potential heart rhythm and neurological effects.
10) Safety profile: side effects and who should be cautious
Like all medicines, Motilium can cause side effects. Many people experience none or only mild effects. However, some reactions require prompt medical attention.
10.1 Common side effects
- Dry mouth
- Headache
- Gastrointestinal effects (e.g., stomach cramps)
- Diarrhoea or changes in bowel habit (may occur)
10.2 Hormone-related effects (prolactin)
Because domperidone affects dopamine pathways, it may increase prolactin in some cases. Potential effects can include:
- Breast tenderness or enlargement
- Milk production (galactorrhoea)
- Sexual dysfunction
- Menstrual changes
10.3 Serious side effects (seek urgent advice)
Contact urgent medical help if you develop:
- Fainting, severe dizziness, or palpitations
- Fast or irregular heartbeat
- Signs of an allergic reaction (swelling of face/lips, rash, difficulty breathing)
- Severe or persistent muscle stiffness, unusual movements, or severe agitation
10.4 Who should be especially cautious
- People with heart rhythm problems or known QT prolongation
- People taking other medicines that may prolong QT
- People with low potassium or magnesium (or conditions causing this)
- People with liver impairment
- Older adults (risk may be higher, so review is essential)
UK safety communications have placed strong emphasis on using the lowest effective dose for the shortest possible duration, and avoiding interacting medicines.
11) Practical use tips
- Take it consistently with the planned timing. If your symptoms are meal-related, consider taking it before meals.
- Stay within the maximum daily dose. Do not “top up” early if symptoms persist without guidance.
- Check your medicine list. Before starting, review whether you take any QT-prolonging medicines or strong CYP3A4 inhibitors.
- Watch your hydration. If you are actively vomiting, you may become dehydrated—seek appropriate advice.
- Keep track of symptom response. If there is no improvement after the expected timeframe, contact a healthcare professional.
12) Missed control and when to seek medical advice
Get urgent medical advice if you have severe pain, blood in vomit or stool, black/tarry stools, difficulty swallowing, unexplained weight loss, symptoms of dehydration, or persistent vomiting that does not settle.
Nausea and vomiting can have many causes—including infections, medication side effects, migraine, pregnancy, bowel obstruction, or metabolic conditions. Motilium may relieve symptoms, but it does not replace assessment when there are warning signs.
13) Alternative options
Depending on your symptoms, the underlying cause, and your medical history, alternative treatments may include:
13.1 For nausea and vomiting
- Other anti-emetic medicines (choice depends on the cause and safety profile)
- Rehydration solutions if vomiting has led to fluid loss
- Addressing triggers (e.g., food-related causes, migraine, motion sickness strategies)
13.2 For indigestion and delayed stomach emptying symptoms
- Acid-suppressing medicines (for reflux-related symptoms)
- Diet and lifestyle measures such as smaller meals, avoiding late-night eating, and reducing trigger foods
- Prokinetic alternatives may be considered by clinicians depending on availability and suitability
If you are considering switching, ask a pharmacist or clinician—especially if you have heart rhythm risk factors or take interacting medicines.
14) UK market/legal context and recent guidance
Domperidone has been subject to extensive safety review in the UK and internationally due to the risk of heart rhythm abnormalities in certain circumstances (QT prolongation).
In response, UK guidance has emphasised:
- Restricted use and careful patient selection
- Lowest effective dose
- Shortest duration consistent with symptom control
- Avoidance of interacting medicines, particularly strong CYP3A4 inhibitors and other QT-prolonging drugs
- Extra caution for people with cardiac conditions, electrolyte disturbances, or liver impairment
UK medicines and regulatory guidance can evolve. Your pharmacist can confirm the latest safety advice for the specific product you’re considering.

16) FAQ (Frequently asked questions)
Can I take Motilium with food?
It’s often recommended to take domperidone before meals if your symptoms are meal-related, because food may slow the onset of effect in some people. Follow the instructions on your product label or leaflet.
How quickly does Motilium work?
Many people notice symptom relief within a short period after taking domperidone, particularly when taken before meals. Response varies between individuals and depends on the cause of nausea or digestive symptoms.
What if my nausea doesn’t improve?
If symptoms do not improve, worsen, or return quickly, seek medical advice. Persistent vomiting or significant abdominal symptoms can have causes that require assessment beyond symptom relief.
Is Motilium safe for everyone?
Not for everyone. Extra caution is needed for people with heart rhythm problems, those taking interacting medicines, people with liver impairment, and older adults. Your pharmacist can help check suitability based on your medicines and health history.
Who should not take Motilium?
You may be advised not to take domperidone if you have specific heart rhythm risks, significant liver impairment, or if you take medicines that strongly interact with domperidone (especially strong CYP3A4 inhibitors and QT-prolonging medicines). Check with your pharmacist.
Can I drive or operate machinery?
Domperidone is not usually associated with strong sedation, but everyone reacts differently. If you feel dizzy or unwell, avoid driving or risky activities.
What side effects should I watch for?
Mild effects like headache or stomach discomfort can occur. Seek urgent help if you experience fainting, severe dizziness, palpitations, rash, or swelling that suggests an allergy.
Can I take Motilium if I’m pregnant or breastfeeding?
Pregnancy and breastfeeding require personalised advice. UK safety guidance and the risk-benefit balance should be discussed with a healthcare professional. If you are pregnant, planning pregnancy, or breastfeeding, speak to your pharmacist before use.
Can I drink alcohol while taking Motilium?
Alcohol may worsen stomach symptoms and could make nausea less manageable. If you choose to drink, do so cautiously and consider avoiding alcohol if you’re currently vomiting or have significant indigestion.
Are there natural alternatives?
Some people find ginger or lifestyle measures helpful for mild nausea, but these do not replace appropriate treatment when symptoms are persistent or severe. If you have heart rhythm risk factors or complex medicine interactions, it’s still important to consult advice.
How should I store Motilium?
Store tablets according to the instructions on the packaging/leaflet (typically at room temperature, away from heat and moisture). Keep out of sight and reach of children.
