Motilium (Domperidone) – Patient Information

Motilium is a brand of domperidone, a medicine used to help control certain stomach and bowel symptoms, particularly where nausea, vomiting, bloating, or delayed stomach emptying are involved. This page explains how Motilium works, how it is typically used, important interactions and safety information, and practical tips for getting the best results.

Important: Always follow the instructions provided by your healthcare professional or those on the product packaging for your specific situation.

Basic product information

• Medicine name: Motilium
• Active ingredient: Domperidone
• Common forms: Oral tablets (and in some markets, oral suspension may be available)
• Therapeutic class (general): Prokinetic/antiemetic (helps move the stomach along and can reduce nausea)

What it’s used for: Motilium is often used for symptoms related to delayed stomach emptying such as nausea, vomiting, upper abdominal discomfort, and bloating.

How Motilium works (mechanism of action)

Domperidone works mainly by blocking dopamine (D2) receptors in specific areas of the brain and the gastrointestinal tract.

• Anti-nausea (antiemetic) effect: By reducing dopamine signalling in the brain’s vomiting centre, domperidone can help lessen nausea and vomiting.
• Prokinetic effect: By blocking dopamine effects on the gut, it can improve movement of the stomach and help reduce symptoms linked to slow gastric emptying (delayed stomach emptying).

In everyday terms, Motilium can help your stomach “move things along” and may reduce the feeling of being sick when the stomach is not emptying properly.

Pharmacokinetics (how the body handles domperidone)

Pharmacokinetics describes what the body does with a medicine—how it is absorbed, distributed, metabolised, and eliminated.

• Absorption: Domperidone is absorbed through the gastrointestinal tract. Absorption can be affected by stomach acidity and by whether you take it with food (see “Food interactions” below).
• Onset of effect: Many people feel effects within 30–60 minutes after taking a dose, though timing varies by person and the reason for use.
• Distribution: Domperidone can distribute into body tissues. It is also associated with limited penetration into the brain compared with some related medicines (this is part of why side effects such as some neurological effects are generally less common than with older dopamine antagonists).
• Metabolism: The liver metabolises domperidone, largely via CYP3A4 enzymes.
• Elimination: Domperidone is eliminated primarily through metabolism and excretion (both in urine and faeces depending on the individual).

Because liver metabolism plays an important role, interactions with medicines that affect CYP3A4 can change domperidone levels in the body.

Typical use and what symptoms it may help

Motilium is commonly used for symptoms related to delayed gastric emptying, including:

• Nausea
• Vomiting
• Feeling overly full (early satiety)
• Upper abdominal discomfort
• Bloating
• Reflux-like symptoms that are linked to stomach not emptying properly

It is often used as a short-term option while the underlying cause of symptoms is addressed (for example, functional dyspepsia, some forms of gastroparesis, or medication-related stomach slowing).

Indications (when Motilium is used)

In Australia, domperidone products have been used for nausea and vomiting and for gastrointestinal motility-related symptoms.

Examples of situations where domperidone may be considered include:

• Nausea and vomiting associated with delayed gastric emptying
• Functional dyspepsia symptoms where stomach emptying is slow
• Some cases of gastroparesis (delayed stomach emptying), particularly where nausea is prominent

Eligibility and suitability depend on age, medical history (especially heart rhythm risk), and the medicines you take.

Dosing (general guidance)

Motilium dosing can vary by age, symptom severity, and product strength/form. Always use the dosage instructions from the relevant product packaging or clinician guidance for your situation.

Common adult dosing patterns (general):

• Adults are often prescribed doses taken up to 3 times daily for nausea and vomiting related to delayed stomach emptying.
• Some regimens use a dose at each meal and at bedtime (depending on the formulation and prescriber instructions).

Children and adolescents: Use in children depends on age, weight, and the condition being treated, and the appropriate formulation. Children require careful dosing and monitoring.

Do not exceed the recommended maximum daily dose listed for your Motilium product. If symptoms persist, it’s important to seek medical advice rather than continuing indefinitely.

Timing: when to take Motilium

Timing can influence how well domperidone works.

• Often best before meals: For many people, taking domperidone before food can improve its effectiveness for nausea and delayed gastric emptying symptoms.
• Follow product instructions: Some formulations recommend taking before meals, while others may be used with or without food depending on symptoms and tolerability.

Practical example: If you’re taking Motilium for nausea related to meals, consider taking it shortly before eating (as advised on your product label) and repeat at the next meal if directed.

Food interactions (what to know)

Food can affect the absorption and effectiveness of domperidone.

• Taking with food may reduce or delay effect: Domperidone may be absorbed less predictably when taken after meals. If you’re using it to prevent nausea around meals, taking it before meals is usually preferred.
• Stomach acidity and digestion: Changes in digestion (for example from certain antacids or acid-suppressing medicines) can influence how quickly domperidone acts.

Tip: If your symptoms are not well controlled, consider adjusting timing (for example, taking before meals) within the boundaries of the product directions. If you are unsure, speak with a pharmacist.

Alcohol and medicine interactions

Alcohol

• Alcohol may worsen nausea and stomach irritation, which can reduce the benefit of Motilium.
• Alcohol can also affect overall safety (for example, dizziness or drowsiness in some people from other medicines you may be taking). If you drink alcohol, keep it moderate and monitor how you feel.

Medicine interactions (especially important)

Domperidone levels and heart rhythm risk can increase when certain medicines are taken together.

• Medicines that inhibit CYP3A4 may increase domperidone levels. Examples can include some antibiotics/antifungals and other medicines used for various conditions. Always check your current list with a pharmacist.
• Medicines that affect heart rhythm (QT interval prolongation) may increase risk when combined with domperidone.
• Strong interacting drugs may be contraindicated. This is particularly relevant for people with existing heart rhythm issues, electrolyte abnormalities, or older age.

Always tell your healthcare professional or pharmacist about every medicine you take, including:

• Prescription medicines
• Pharmacy (over-the-counter) medicines
• Herbal products and supplements
• Any known heart conditions

Safety profile and who should take extra care

Like all medicines, Motilium can cause side effects. Most people tolerate it well, but certain risks are more serious and should be considered.

Common side effects

• Dry mouth
• Headache
• Stomach/intestinal effects such as cramps or diarrhoea (less common)
• Changes in appetite (individual)

Less common but important considerations

• Increased prolactin-related effects: Domperidone can raise prolactin in some people. This may lead to breast tenderness or milk production, changes in menstrual cycle, or sexual side effects.
• Allergic reactions: Seek urgent help if you develop signs of allergy such as swelling of the face/lips, rash, or difficulty breathing.

Heart rhythm risk (QT prolongation)

Domperidone has been associated with QT interval prolongation (a change in the heart’s electrical timing) which, in rare cases, may lead to serious rhythm disturbances—particularly at higher doses, in older adults, or when combined with certain interacting medicines.

You should take extra care if you have:

• Known heart rhythm problems
• A history of fainting or unexplained dizziness
• Low potassium or magnesium levels (for example due to some diuretics or severe vomiting/diarrhoea)
• Significant liver impairment
• Taking medicines known to affect heart rhythm or increase domperidone levels

Seek urgent medical advice if you experience palpitations, fainting, severe dizziness, or symptoms suggestive of an abnormal heart rhythm.

Long-term use

Domperidone is generally used for symptom control rather than lifelong treatment. If symptoms persist, it’s important to review the diagnosis and overall management strategy.

Practical use tips

• Match timing to symptoms: If nausea is meal-related, taking Motilium shortly before meals may help.
• Use the lowest effective dose: This can reduce the chance of side effects.
• Don’t “double up”: If you miss a dose, take the next one at the correct time unless packaging guidance says otherwise.
• Track response: Note how quickly symptoms improve and whether they return at the same times of day.
• Hydration: If vomiting occurs, focus on hydration and seek medical help if you cannot keep fluids down.
• Review ongoing medicines: If you start new treatments (especially antibiotics, antifungals, or other medicines), ask about interactions with domperidone.

Alternative options

If Motilium isn’t suitable or doesn’t provide adequate relief, several alternative approaches may be considered depending on the underlying cause.

Other medicine options (examples)

• Antiemetics (to help nausea/vomiting) such as options from different drug classes may be used depending on your condition.
• Acid-suppressing therapy (for reflux-related symptoms) if the main issue is heartburn or acid irritation.
• Prokinetic alternatives (depending on availability and suitability) where appropriate for delayed gastric emptying.

Non-medicine strategies

• Meal adjustments: smaller, more frequent meals
• Reduce triggers: fatty foods, very large meals, and lying down soon after eating
• Manage constipation if present
• Review other medicines that may slow the stomach (for example, some pain medicines or other drugs)

Your pharmacist or healthcare professional can help determine which alternatives are most appropriate for you.

Motilium in Australia: market and legal context

In Australia, medicines are regulated by the Therapeutic Goods Administration (TGA). The availability of domperidone-containing products and the conditions of supply (including whether particular formulations are available over the counter or via prescription-only pathways) may vary depending on current regulatory status.

Why this matters: Supply and advice requirements are designed to reduce risks, particularly those related to heart rhythm and medicine interactions. As a result, you may be asked screening questions when purchasing domperidone-containing products online.

Regulatory updates: Domperidone guidance has evolved internationally to improve safety (for example, emphasis on limiting dose and avoiding interacting medicines, and careful consideration in older adults or those with cardiac risk factors). Australia aligns with safety-focused recommendations.

Recent guidance (safety-focused themes)

While exact product instructions can change over time, recent guidance worldwide has typically highlighted:

• Use the lowest effective dose for the shortest duration needed.
• Avoid or closely screen for interacting medicines that raise domperidone levels or increase QT risk.
• Extra caution in older adults and people with heart rhythm risks.
• Review suitability in liver impairment.

If you’re unsure whether your medicines are a concern, ask a pharmacist before taking Motilium.
