Motilium (Domperidone) — Patient Information (Australia)

Motilium is a brand of domperidone, a medicine used to help relieve certain stomach-related symptoms, especially nausea and feelings of fullness. In Australia, Motilium is supplied by pharmacies and may be used for specific indications based on your symptoms and medical history.

This guide explains how Motilium works, how it is used, important safety considerations (including interactions), and practical tips to help you use it effectively and safely.

Key Product Information

• Active ingredient: Domperidone
• Brand: Motilium
• Type: Anti-nausea / prokinetic agent (works on the gastrointestinal tract and related pathways)
• Common forms: Tablets and some formulations may include oral suspension (depending on availability)
• Where to use: Australia (availability can vary by formulation)

Note: Always check your product pack for the exact strength (e.g., mg per tablet) and directions specific to the formulation you have.

How Motilium Works (Mechanism of Action)

Domperidone helps relieve symptoms such as nausea and delayed stomach emptying. It does this mainly by blocking dopamine receptors:

• Blocks dopamine (D2) receptors in the digestive tract and an area of the brain involved in nausea and vomiting.
• Promotes gastric motility (helps the stomach move contents along more effectively).
• Supports more normal stomach emptying, which can reduce:
  • nausea
  • early satiety (feeling full quickly)
  • bloating/upper abdominal discomfort due to slow digestion

For some people, domperidone may also reduce nausea by acting on the nausea pathways in the central nervous system—although its ability to cross into the brain is limited compared with some other dopamine-blocking medicines.

Pharmacokinetics (How the Body Handles Domperidone)

Pharmacokinetics describe what happens to a medicine in the body: absorption, distribution, metabolism, and elimination.

• Absorption: Domperidone is absorbed after oral dosing. Absorption can be influenced by stomach acidity and food intake (see “Food interactions” below).
• Distribution: It distributes into body tissues; it is also found in the brain to a lesser extent than some similar medicines.
• Metabolism: Domperidone is metabolised primarily in the liver, involving enzymes such as CYP3A4.
• Excretion: It is eliminated through both urine and faeces.
• Half-life: The time taken for the body’s level to reduce by half varies among individuals and may be longer in older adults or those with organ impairment.

Why this matters: Because domperidone is metabolised by CYP3A4 and can affect heart rhythm in certain situations, interactions with other medicines and individual risk factors are important for safe use.

Typical Uses and Indications

Motilium (domperidone) is used to relieve symptoms related to impaired stomach emptying and nausea. Typical indications may include:

• Nausea and vomiting
• Upper gastrointestinal discomfort such as:
  • feeling overly full
  • bloating
  • discomfort associated with slow digestion

Important: The exact use may depend on the product formulation and locally approved indications. If your symptoms are severe, persistent, unexplained, or associated with “red flags” (below), seek medical advice promptly.

Seek urgent advice if you have

• chest pain, fainting, or a known history of significant heart rhythm problems
• blood in vomit, black/tarry stools, or severe abdominal pain
• involuntary weight loss, trouble swallowing, or vomiting that persists
• pregnancy complications or severe dehydration

When to Take Motilium (Timing and How to Use)

Timing can influence how well domperidone works. A common practical approach is:

• Take before meals if you are using it for symptoms linked to eating and stomach emptying.
• If using after meals, it may be less effective for some symptoms (timing depends on your situation and formulation).

General guidance: Follow the instructions on your pack or label. If you are unsure, ask your pharmacist for advice.

Practical example schedule

• For nausea/fullness with meals: Take a dose shortly before breakfast and/or before dinner, as directed.
• For episodic symptoms: Use only when you need it, for short periods, unless your clinician advises otherwise.

Tip: Keep a simple diary noting when symptoms occur and what you ate. This can help you and your pharmacist determine the best timing.

Dosing (Adults and Special Situations)

Because individual products and local guidelines may differ, dosing should be based on the specific strength and instructions provided with your Motilium product.

Common dosing approach (adult guidance)

• Typical adult dosing is often given as multiple doses per day.
• The lowest effective dose for the shortest possible duration is generally recommended for safety.

Maximum doses: There is an important safety emphasis on not exceeding recommended maximums, especially in higher-risk groups. Always check your pack or pharmacist advice.

Older adults, kidney/liver impairment, and heart rhythm risk

• Older adults: Risk of heart rhythm effects may increase with age, so dose selection and duration should be cautious.
• Kidney impairment: Domperidone and/or its metabolites may accumulate; dosing adjustments may be needed.
• Liver impairment: Use may be restricted or not advised depending on severity.
• Heart rhythm (QT prolongation) risk: Do not use domperidone if you have certain rhythm problems or if you are taking medicines that raise domperidone levels or affect QT interval (see “Medicine and alcohol interactions”).

If you miss a dose: Take it when you remember unless it is close to your next dose. Do not take double the dose.

Food Interactions

Food can influence domperidone absorption and how quickly it works.

• Taking Motilium before meals may improve effectiveness for symptoms of nausea and delayed gastric emptying.
• Some people find that taking it with or after food delays onset.
• High-fat meals may slow gastric emptying and can affect absorption timing for some medications.

Acid-related medicines: Because stomach conditions and acid-suppressing therapy can influence absorption, it’s important to mention to your pharmacist if you take medicines such as:

• antacids
• proton pump inhibitors (PPIs)
• H2-receptor antagonists (H2 blockers)

Your pharmacist can advise the best timing and whether any change is needed.

Alcohol and Medicine Interactions

Alcohol

There is no single “universal” rule that domperidone cannot be used with alcohol, but alcohol can worsen nausea, dizziness, and dehydration. Alcohol may also affect how you tolerate side effects. For safety:

• Limit or avoid alcohol while you are taking Motilium, especially if you feel unwell or dizzy.
• If you drink alcohol, do so in moderation and avoid if you notice increased dizziness or worsening stomach symptoms.

Medicine interactions (very important)

Domperidone has interaction risks because it can be affected by liver metabolism and because it may affect the heart’s electrical activity (QT interval). Avoiding interactions is one of the most important parts of safe use.

Do not combine Motilium with certain medicines that can:

• increase domperidone levels (e.g., strong CYP3A4 inhibitors)
• prolong the QT interval or increase arrhythmia risk

Examples of medicines that may be problematic include (not exhaustive):

• Some antibiotics/antifungals: e.g., certain macrolides and azole antifungals
• Some antivirals
• Some psychiatric medicines (depending on type and dose)
• Some antiarrhythmics
• Some medicines for nausea/migraine that also affect QT interval
• Other drugs affecting CYP3A4 metabolism

What to do:

• Tell your pharmacist about all medicines you take, including supplements and “over-the-counter” products.
• If you start or stop any medicine, ask whether your Motilium dose/timing should change.
• If you feel faint, have palpitations, or develop severe dizziness, seek urgent medical attention.

Safety Profile and Side Effects

Like all medicines, domperidone can cause side effects. Most people experience no serious problems, but it is important to be aware of the risks—especially heart rhythm concerns.

Common side effects

• headache
• dry mouth
• stomach cramps or diarrhoea
• changes in appetite

Less common but important side effects

• Raised prolactin levels (because of dopamine blockade), which can lead to:
  • breast tenderness or enlargement
  • galactorrhoea (milk discharge)
  • sexual dysfunction
• Allergic reactions (rare): swelling, rash, or breathing difficulty

Serious risks (seek urgent advice)

• Heart rhythm changes (QT prolongation) that can rarely lead to serious arrhythmias
• Fainting, severe dizziness, or palpitations

Who may be at higher risk?

• people taking interacting medicines that raise domperidone levels
• people with existing QT prolongation or certain heart conditions
• people with significant electrolyte disturbances (low potassium/magnesium)
• older adults

General safety principles: use the lowest effective dose, for the shortest duration, and avoid prohibited combinations.

Practical Use Tips (How to Get the Best Results)

• Take it at the right time: before meals for meal-related nausea/fullness.
• Use only when needed: if symptoms are intermittent, avoid taking regularly long-term unless advised.
• Keep hydrated: if nausea is significant, small sips of water or oral rehydration can help.
• Track symptoms: note severity, timing, triggers (food, stress), and response to Motilium.
• Avoid triggers: heavy meals, fatty foods, and lying down soon after eating can worsen delayed gastric emptying.
• Consider non-medicine strategies: smaller meals, slower eating, and elevating head of bed may reduce reflux-related symptoms.

If symptoms don’t improve within a short period or keep returning, don’t just increase dosing—seek advice so the underlying cause can be assessed.

Alternative Options

If Motilium doesn’t suit you or isn’t effective enough, your pharmacist or clinician may consider other options depending on the cause of symptoms.

Possible alternatives for nausea and indigestion-related symptoms

• Other anti-nausea medicines (choice depends on cause and safety profile)
• Acid-reducing medicines if symptoms are mainly due to reflux/heartburn
• Medicines targeting stomach movement (some have different interaction and safety considerations)
• Non-medicine approaches such as dietary adjustment, hydration strategies, and symptom management plans

Important: Many nausea medicines can have similar interaction risks. Always ask your pharmacist about suitability—especially if you take other medicines or have heart rhythm risk factors.

Motilium in the Australian Market: Legal and Regulatory Context
