Motilium (Domperidone) – Patient Information (Australia)

Motilium is a brand of the medicine domperidone. It is used to help relieve symptoms related to slow stomach emptying and certain nausea-related conditions. This page explains how Motilium works, when it’s typically used, how to take it, and important safety considerations—written in a patient-friendly way for people in Australia.

At a Glance

• Active ingredient: Domperidone
• Common uses: Nausea, feeling sick, indigestion related to delayed stomach emptying
• How it works: Helps move food through the stomach and reduces nausea
• Typical forms: Tablets (and some markets may also offer other presentations—availability can vary)
• Key safety focus: Heart rhythm concerns in certain people, especially at higher doses or with interacting medicines

Basic Product Information

Note: Always check your product packaging and the instructions provided with your specific Motilium brand and strength.

How Motilium Works (Mechanism of Action)

Domperidone works mainly by blocking dopamine receptors in the body, especially pathways involved in nausea and stomach movement.

• Anti-nausea effect: Dopamine receptor blockade helps reduce nausea and vomiting signals.
• Prokinetic effect: It can improve the movement of food through the gastrointestinal tract by enhancing coordination of stomach and upper digestive tract activity.
• Improves symptoms of delayed emptying: When the stomach empties more slowly than usual, symptoms like early fullness, bloating, nausea, and reflux-like discomfort may occur; Motilium may help relieve these.

Motilium is not a pain-reliever. It targets nausea and motility-related symptoms.

Pharmacokinetics (How the Body Processes Domperidone)

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

• Absorption: Domperidone is absorbed after oral dosing. Absorption can be affected by food (see “Food interactions” below).
• Distribution: The medicine distributes throughout the body. It does cross into the brain to a limited extent compared with some other dopamine-blocking medicines, which is why it may have fewer central side effects for many people.
• Metabolism: Domperidone is metabolised mainly in the liver, with involvement of drug-metabolising enzymes (notably CYP3A4).
• Elimination: It is eliminated through a combination of urine and faeces over time.
• Heart rhythm considerations: Because domperidone can affect heart electrical activity in some circumstances, kidney/liver function and interacting medicines matter for overall risk.

Practical meaning: This is why it’s important to follow dose limits and to mention all medicines you take, including some antifungals and certain antibiotics/antidepressants, to reduce the chance of interactions.

Typical Use in Australia

Motilium is commonly used to help relieve symptoms associated with delayed gastric emptying and nausea. People may take it when they feel:

• Nausea or a feeling of being sick
• Indigestion associated with slow stomach emptying
• Feeling full early (early satiety)
• Bloating and discomfort after meals
• Discomfort related to upper gastrointestinal motility problems

Important: If symptoms are severe, persistent, unexplained, or accompanied by red flags (such as vomiting blood, black stools, unexplained weight loss, difficulty swallowing, or persistent severe abdominal pain), seek medical advice promptly.

Indications (What It’s Used For)

Indications can vary slightly by product and time period. In general, domperidone is indicated for:

• Nausea and vomiting (including symptoms related to delayed gastric emptying)
• Dyspepsia (indigestion) symptoms associated with impaired stomach motility

Some conditions causing nausea may require different treatment. Motilium is a symptom-targeted option for motility-related problems.

How to Take Motilium (Timing and Practical Use)

Correct timing helps domperidone work effectively and safely.

When to take it

• Before meals: Domperidone may work best when taken before meals for motility-related symptoms (for example, nausea or fullness after eating).
• If you forget a dose: Take it when you remember unless it’s close to your next dose. Do not take a double dose.

How long to use it

• Use the shortest time needed to control symptoms.
• If symptoms do not improve or keep returning, it’s important to discuss underlying causes with a healthcare professional rather than continuing indefinitely.

Dosing (General Guidance)

Dose depends on age, symptom severity, and individual risk factors (including heart rhythm risk and liver/kidney function). Follow the product label or your clinician’s instructions.

General principles (not a personalised prescription):

• Use the lowest effective dose for the shortest duration.
• Do not exceed recommended daily limits. Higher doses increase risk of cardiac rhythm problems.
• Children: Dosing for children must be based on age/weight and suitability; do not use adult dosing without correct guidance.
• Older adults: Many older adults may have increased sensitivity to medicines and may have kidney/liver changes; risk review is important.

Because domperidone dosing recommendations have been refined in response to safety updates, it’s particularly important to ensure you are using the correct dose strength and frequency for your age and situation.

Food Interactions (Including Tea, Coffee, and Meals)

Food can affect how quickly domperidone is absorbed and how well it works.

• Take before meals for best effect, especially if you’re taking it for nausea or stomach-related symptoms after eating.
• If taken with food, absorption may be reduced. This can lead to slower or weaker symptom relief.
• General meals: Standard food effects vary by person; however, consistent “before meals” timing is usually preferred unless your clinician advised otherwise.

Tip: If your symptoms are worse at certain times (for example, after dinner), taking Motilium about before that meal may help.

Alcohol Interactions

Domperidone is not typically known for a strong direct alcohol interaction. However, alcohol can:

• Worsen nausea, reflux, stomach irritation, and dizziness in some people
• Increase the risk of side effects such as light-headedness

Practical approach: If you choose to drink alcohol, keep it moderate and observe how you feel. Avoid alcohol if it worsens symptoms or causes dizziness.

Medicine Interactions (Very Important)

Interactions are one of the most important safety considerations with domperidone. Some medicines can increase domperidone levels or increase the risk of heart rhythm disturbances.

Tell a healthcare professional/pharmacist if you take:

• Medicines that affect heart rhythm (QT prolongation), especially certain antiarrhythmics
• Some antibiotics (for example, certain macrolides and others that can affect QT)
• Some antifungal medicines (azole antifungals)
• Some antidepressants and antipsychotics
• Medicines that inhibit CYP3A4 (this can raise domperidone blood levels)
• Other nausea medicines or dopamine-blocking medicines

Herbal and “over-the-counter” interactions

• Even “natural” products can affect drug metabolism. Check with a pharmacist if you use herbal supplements.
• Always bring a list of all products (including vitamins, supplements, and OTC medicines) when seeking advice.

Practical safety tip: Before starting Motilium, confirm with your pharmacist that the combination of medicines you’re using is safe—particularly if you take medicines for heart conditions, mental health, infections, or fungal infections.

Safety Profile and Side Effects

Most people tolerate Motilium well, but it’s important to know possible side effects and when to seek help urgently.

Common or mild side effects

• Dry mouth
• Headache
• Stomach cramps or diarrhoea in some people
• In some cases, increased appetite or changes in bowel habits

Breast-related effects (due to hormone changes)

Domperidone can affect prolactin (a hormone). This may lead to:

• Breast tenderness
• Breast enlargement
• Milk discharge (galactorrhoea), including in people who are not breastfeeding
• Changes in menstrual cycle

Less common but serious risks

The safety focus for domperidone is heart rhythm. In certain individuals, it may be associated with abnormal heart rhythms (QT prolongation), which can rarely lead to serious outcomes.

• Seek urgent help if you experience symptoms such as fainting, severe dizziness, a very fast/irregular heartbeat, or sudden shortness of breath.

Higher-risk situations

• Existing heart rhythm problems or significant heart disease
• Low potassium or magnesium levels
• High domperidone dose or use for longer periods than recommended
• Use of interacting medicines that raise domperidone exposure or affect QT
• Significant liver impairment
• Kidney impairment (may require dose adjustment and monitoring)

Practical Use Tips (For Better Results and Safety)

• Use “before meals” timing if you’re taking it for post-meal nausea or fullness.
• Keep a symptom diary (what you ate, when you took Motilium, symptom intensity). This helps identify triggers and whether domperidone is helping.
• Check your medicine list each time you refill or start a new medicine—especially antibiotics, antifungals, antidepressants, and heart medications.
• Avoid exceeding recommended dose. If symptoms persist, don’t increase the dose on your own—seek advice.
• Review risk factors if you are older, have heart disease, kidney/liver impairment, or electrolyte problems.
• Stop and seek advice if you develop concerning symptoms like fainting, severe palpitations, or persistent severe side effects.

Missed Dose and Overuse Advice

• Missed dose: Take it when you remember unless it’s near your next scheduled dose.
• Overuse: Taking more than recommended can increase side effects and cardiac risk. If an overdose is suspected, seek urgent medical advice.

Alternative Options

Alternative treatments depend on the underlying cause of your symptoms (for example, reflux/indigestion, infection-related nausea, migraine, pregnancy-related nausea, or gastroparesis).

Common alternatives (examples)

• Reflux and indigestion medicines such as antacids and acid reducers (depending on symptoms)
• Other anti-nausea medicines (selected based on cause and safety profile)
• Prokinetic options used in certain digestive motility conditions (availability depends on jurisdiction and clinical assessment)
• Non-medicine strategies
  • Smaller meals and avoiding large/high-fat meals
  • Staying upright after eating
  • Reducing alcohol and caffeine if they worsen symptoms
  • Identifying food triggers
  • Managing constipation if present

Tip: If Motilium doesn’t provide adequate relief, persistent nausea or indigestion may require a different approach, including investigations.

Motilium and Special Considerations

Kidney impairment

Kidney function can affect how domperidone is cleared. Dose adjustments or extra caution may be required.

Liver impairment

Because domperidone is metabolised in the liver, caution is needed in people with liver problems. If you have liver impairment, discuss suitability with a healthcare professional.

Pregnancy and breastfeeding

If you are pregnant, planning pregnancy, or breastfeeding, you should seek advice before using domperidone. The safety balance depends on your individual situation and the reason for treatment.

Children

Use in children requires appropriate dosing and suitability. Confirm appropriate formulation and dosing with a pharmacist or clinician.

Market and Legal Context for Australia (What to Know)

In Australia, medicine availability, supply arrangements, and labelling requirements are regulated to support safety and appropriate use. Domperidone-containing products may be subject to supply restrictions and specific patient information requirements.

Why this matters: Domperidone has had revised safety recommendations over time related to heart rhythm risk. Australian regulators and professional guidance have emphasised dose limits, avoidance of interacting medicines, and risk screening.

Always check: The directions on the specific Motilium product you receive and confirm the dose strength matches your intended use.

Recent Guidance and Safety Updates (High-Level)

Domperidone has been reviewed internationally and guidance has generally focused on reducing the risk of serious heart rhythm events. Key themes in current practice include:

• Using the lowest effective dose
• Limiting treatment duration to what’s needed for symptom control
