Motilium (Domperidone) – Patient Information (Australia)

Motilium is a brand of domperidone, a medicine used to relieve symptoms related to slow stomach emptying and certain types of nausea and vomiting. This page explains what Motilium is, how it works, how it’s used, important safety considerations, and practical tips for using it effectively.

Always read the Consumer Medicine Information (CMI) leaflet supplied with your medicine and follow the instructions provided by your pharmacist or healthcare professional.

1) Basic product information

• Medicine name: Motilium
• Active ingredient: Domperidone
• Common forms: Tablets and oral formulations (varies by brand and availability)
• What it’s used for: Nausea and vomiting; symptoms of delayed stomach emptying (including upper abdominal discomfort and fullness)

Brand notes: Product strengths and formulations may vary. Check your pack for the exact strength (e.g., mg per tablet) and dosing instructions.

2) How Motilium works (mechanism of action)

Domperidone works mainly by affecting dopamine receptors in the body.

• It acts as a peripheral dopamine (D2) receptor antagonist—meaning it blocks dopamine signals in key areas involved in stomach movement.
• By reducing dopamine’s calming effect on the digestive tract, it can help improve gastric motility (the movement of the stomach and upper gut).
• It also helps to reduce nausea and vomiting by influencing pathways involved in the vomiting reflex.

In plain terms: Motilium can help your stomach empty more effectively and can reduce the feeling of sickness caused by delayed digestion.

3) Pharmacokinetics (how the body handles domperidone)

Pharmacokinetics describe what happens after you take a medicine: absorption, distribution, metabolism, and elimination.

• Absorption: Domperidone is absorbed after oral dosing. Absorption may be affected by whether you take it with food.
• Time to effect: Some symptom relief may be felt within a short period after dosing, especially for nausea, though individual response varies.
• Distribution: Domperidone distributes throughout the body. It does not readily cross into the brain compared with some related medicines, which is one reason it’s associated with fewer central nervous system effects.
• Metabolism: It is metabolised mainly in the liver.
• Excretion: Elimination occurs via both urine and faeces (proportions vary).
• Kidney and liver considerations: People with kidney impairment may have different elimination patterns, and dose adjustments or extra caution may be required.

Why this matters: Your doctor or pharmacist may recommend timing changes (e.g., with or without food) and may consider your liver/kidney function when recommending a dose.

4) Typical use in Australia

Motilium is commonly used to relieve symptoms such as:

• Nausea (the urge to vomit)
• Vomiting
• Upper gastrointestinal discomfort associated with delayed gastric emptying
• Feeling full quickly and upper abdominal bloating after meals

Important: If you have persistent vomiting, severe abdominal pain, blood in vomit, black/tarry stools, unexplained weight loss, or symptoms that worsen, seek medical advice promptly.

5) Indications (what it is meant to treat)

Domperidone is indicated for the relief of:

• Nausea and vomiting
• Symptoms of delayed gastric emptying (e.g., upper abdominal fullness/discomfort, early satiety)

Guidance for use: Motilium is intended for symptom control. It does not treat the underlying cause of nausea if that cause is something else (for example, infection, migraine, pregnancy, or obstruction).

6) How to take Motilium (timing and dosing)

Dose and frequency can vary depending on the reason you’re taking it, your age, and other factors (such as kidney function). Always use the dose on your label or as directed in the CMI.

Typical timing

Motilium can be taken:

• Before meals when used for symptoms related to digestion (often helps because it supports gastric motility).
• As directed on your packaging for nausea.

Food interactions: should you take it with or without food?

Food can influence domperidone absorption and how well it works for nausea.

• For best effect on nausea/upper stomach symptoms: taking Motilium before meals may be preferable.
• If your prescriber or pharmacist advised otherwise: follow their instructions.

Alcohol

There is no simple “safe amount” of alcohol with domperidone for everyone, because alcohol can worsen nausea and dizziness for some people. If you drink alcohol, consider:

• Limiting alcohol while you’re treating nausea.
• Avoiding alcohol if you notice drowsiness, dizziness, or worsening stomach symptoms.

Dosing overview (adult)

Because products and strengths differ, use your pack instructions. In general, domperidone is taken in multiple daily doses for symptomatic relief, and the lowest effective dose for the shortest duration is commonly preferred.

Do not exceed the recommended dose on your label. If your symptoms persist or recur, speak to a pharmacist or doctor rather than increasing the dose.

Dosing overview (children/teens)

Domperidone dosing in children is more specific and depends on age and weight, and safety considerations are particularly important. Follow the dosing instructions exactly as provided by your pharmacist or the product leaflet.

7) Food and drug interactions

Food interactions

Food may reduce or delay absorption. For many people, Motilium works best when taken before meals. If you’re unsure, ask your pharmacist about your specific product and how to time it with eating.

Medicine interactions (especially important)

Some medicines can change how domperidone works in the body or increase the risk of side effects (particularly effects on heart rhythm).

Tell your pharmacist if you take any of the following:

• Medicines that prolong the QT interval (a measure related to heart rhythm), such as some antiarrhythmics and certain antibiotics/antifungals.
• Strong inhibitors of liver enzymes (CYP3A4) can raise domperidone levels and may increase risk.
• Some antiviral medicines and other prescription medicines that affect metabolism.
• Medicines for nausea or reflux (to avoid duplication or conflicting effects).
• Antipsychotic medicines or dopamine-related medicines (may affect overall benefit and side effects).

General rule: Always check interactions before starting Motilium, especially if you take multiple medicines.

8) Safety profile and who should be extra careful

Most people tolerate Motilium well when used correctly. However, like all medicines, it can cause side effects and has precautions.

Common side effects

• Dry mouth
• Headache
• Gastrointestinal effects such as cramps or diarrhoea (less commonly)

Less common but important risks

• Breast milk-related changes or increased prolactin levels in some individuals (may cause breast tenderness or changes).
• Allergic reactions (seek urgent help if you develop swelling of the face/lips, difficulty breathing, or widespread rash).
• Heart rhythm concerns: Domperidone has been associated with QT interval prolongation in some circumstances, which can rarely lead to serious rhythm disturbances.

When extra caution is needed

Speak to a pharmacist or doctor before using Motilium if you have any of the following:

• Existing heart rhythm problems or a history of prolonged QT
• Low potassium or magnesium levels (for example from certain diuretics or prolonged vomiting/diarrhoea)
• Significant liver disease
• Use of other medicines known to affect heart rhythm or domperidone metabolism
• You are pregnant, breastfeeding, or planning pregnancy (risk/benefit should be considered)

Urgent advice: If you experience fainting, severe dizziness, palpitations, or sudden shortness of breath, seek urgent medical attention.

9) Practical use tips

• Use the correct timing: for many people, taking Motilium before meals improves effectiveness for digestion-related symptoms.
• Use the lowest effective dose: if symptoms improve, don’t continue longer than needed unless advised.
• Track triggers: note whether symptoms are linked to specific foods, stress, or irregular meals.
• Stay hydrated if you’re experiencing nausea/vomiting.
• Avoid duplicating anti-nausea medicines: check your medicine list to avoid taking overlapping products without advice.
• Consider lifestyle adjustments: smaller meals, avoiding late-night eating, and reducing alcohol can help nausea for many people.

10) Alternative options for nausea and delayed stomach emptying

Alternatives depend on the cause of your symptoms (e.g., reflux, gastroenteritis, migraine, pregnancy-related nausea, medication side effects, or a functional bowel disorder). Common options include:

For reflux and upper gut symptoms

• Antacids or alginate-based products for occasional heartburn
• Acid suppressing medicines (e.g., proton pump inhibitors or H2 blockers—chosen based on your symptoms)

For nausea/vomiting

• Other antiemetics (choice depends on the cause and your health profile)
• Non-medicine strategies such as hydration, small sips, and diet adjustments

For slow gastric emptying (gastroparesis)

• Prokinetic treatments and dietary strategies may be recommended by a clinician
• In some cases, a targeted treatment plan is required rather than short-term symptom relief

Discuss with a pharmacist: If you need frequent or long-term control, a tailored approach is usually safer and more effective than repeating short courses.

11) Market and legal context for Australia

In Australia, medicines containing domperidone have been subject to ongoing regulatory review and risk management. Safety communications have focused on heart rhythm risk and on careful prescribing, dose selection, and interaction checking.

Key points that may be reflected in current Australian practice include:

• Careful attention to dosing limits and the total daily amount
• Avoiding or limiting certain combinations with medicines that increase domperidone levels or risk of QT prolongation
• Heightened caution in people with cardiac risk factors or electrolyte imbalance

Availability: Depending on formulation and strength, domperidone products may be supplied through pharmacy channels as allowed under Australian medicines scheduling and local pharmacy requirements.

12) Recent guidance and what it means for you

Over time, Australian and international safety reviews have emphasised:

• Using domperidone only when appropriate for the symptoms it is intended to treat
• Checking medicine interactions, especially with drugs that affect metabolism or heart rhythm
• Using the lowest effective dose and reviewing the need for continued use if symptoms persist

For patients: If you’ve previously used Motilium without problems but now take new medicines (including antibiotics, antifungals, antivirals, or antidepressants/antipsychotics), it’s important to re-check interactions.

13) Delivery and availability (online pharmacy)

Motilium products may be available through Australian online pharmacies depending on current stock levels and permitted supply arrangements.

• Dispatch: Orders are typically dispatched after processing and verification.
• Delivery: Delivery time depends on your location and carrier service level.
