Quick overview

• Active ingredient: Domperidone
• Brand name: Motilium (UK)
• What it is used for: Relief of symptoms such as nausea/vomiting and indigestion associated with delayed stomach emptying (e.g., upper abdominal fullness)
• Common forms: Tablets and liquid (strengths vary by product)
• How it works: Helps improve stomach movement and reduces nausea

Basic product information

How Motilium works (mechanism of action)

Domperidone works mainly by acting as an antagonist of dopamine (D2) receptors in the body’s digestive system. Dopamine influences the movement of the gut and the brain’s vomiting centres. By blocking these receptors, domperidone:

• Improves gastric motility (helps the stomach empty more effectively)
• Helps reduce nausea and vomiting signals
• May increase the coordination of digestion between the stomach and upper intestine

Unlike some older medicines in this category, domperidone has less penetration into the brain, which may reduce the risk of some central nervous system effects.

Pharmacokinetics: what the body does to domperidone

Pharmacokinetics describes how the body absorbs, distributes, metabolises, and eliminates a medicine.

• Absorption: Domperidone is absorbed from the gut, but how quickly it reaches peak levels can vary depending on the presence of food.
• Peak levels (Tmax): Levels typically rise within about 1 hour after taking a standard oral dose (but may differ with formulations and timing).
• Distribution: The medicine is distributed throughout the body; it is not confined to the gut.
• Metabolism: Domperidone is metabolised mainly in the liver by enzymes of the CYP system, especially CYP3A4.
• Elimination: It is cleared through both metabolism and excretion, with a terminal elimination period that can be longer in certain people.
• Liver and kidney effects: Your dose and suitability may need adjustment if you have liver or significant kidney problems.

Why this matters: The way your body processes domperidone can be affected by other medicines (particularly those that inhibit CYP3A4). This can increase exposure and may raise the risk of side effects, including effects on the heart rhythm.

Typical uses and indications

In the UK, Motilium is used to relieve symptoms associated with delayed gastric emptying and related nausea/vomiting. Typical indications include:

• Nausea and vomiting
• Indigestion and upper abdominal discomfort linked to slow stomach emptying
• Feeling of fullness, bloating, or discomfort after meals (where appropriate)

It is important to note that persistent or severe symptoms may have causes that require assessment. Seek medical advice if symptoms do not improve or you have warning signs (see “Safety profile” and “FAQ”).

When and how to take Motilium (timing)

Timing can help effectiveness: Motilium is often recommended to be taken before meals for better relief of post-meal symptoms.

• For nausea or symptoms after eating: take doses before meals (as advised)
• If taken for vomiting: follow dosing instructions carefully and consider advice from a clinician for ongoing symptoms
• If you miss a dose: take it when you remember unless it is close to the next dose—then skip the missed dose and resume your schedule

Do not double up to make up for a missed dose.

Dosing: typical adult and child guidance

Important: The correct dose depends on age, symptom severity, and other health factors (including liver/kidney function and interacting medicines). Use the dose on the pack and/or the advice you were given.

Below is general patient-friendly information about common dosing patterns. For exact dosing, always refer to your specific product packaging and instructions.

Adults

• Common regimens often involve dosing up to three times a day and are usually limited to the lowest effective dose for the shortest required period.
• The total daily dose may differ by formulation and by your individual risk profile.

Children

• Dosing in children must be age-appropriate and weight-appropriate, and should be determined by a clinician or pharmacist.
• Not all formulations are suitable for all paediatric ages; always check the specific product information.

Older adults and people with liver/kidney problems

• Older adults and those with liver impairment or significant kidney impairment may need dose adjustments and extra monitoring.
• Follow professional advice closely; do not increase dose on your own.

Heart rhythm considerations: Because domperidone can, in some people, affect heart rhythm (see “Safety profile”), dose should not be exceeded and interacting medicines should be avoided.

Food interactions and effects on absorption

Food can influence how domperidone is absorbed and when it begins to work. In practical terms:

• Taking Motilium before meals may improve effectiveness for symptoms related to eating and digestion.
• Taking it with food may delay absorption and slow the onset for some people.

How to choose timing: If your main problem occurs after meals, using a before-meal schedule is often helpful. If your clinician/pharmacist advised otherwise for your specific situation, follow that guidance.

Alcohol interactions

There is no universal “must avoid” rule for alcohol with domperidone, but caution is sensible:

• Alcohol may worsen nausea and indigestion symptoms on its own, which can make it harder to judge whether Motilium is helping.
• Alcohol can affect sleep, hydration, and general wellbeing, which may indirectly affect side effects.
• If you feel dizzy or unwell while taking Motilium, avoid alcohol and seek advice.

If you drink alcohol regularly (or in large amounts), discuss it with a pharmacist or doctor—especially if you have liver problems or take other medicines.

Other medicine interactions (including key warnings)

Some medicines can increase domperidone levels by affecting liver enzymes (particularly CYP3A4) or can also influence the heart rhythm. This can raise the risk of serious side effects.

Medicines that may increase risk of heart rhythm problems

Avoid using domperidone with other medicines that prolong the QT interval or affect heart rhythm, unless a healthcare professional specifically advises it and monitoring is appropriate.

Medicines that inhibit CYP3A4

CYP3A4 inhibitors can increase domperidone concentrations. Examples (not a complete list) may include:

• Some antifungal medicines
• Some antibiotics (certain macrolides)
• Some antidepressants and other medicines that may affect CYP3A4

Always check interactions when starting new medicines. Inform your pharmacist about:

• All prescription medicines
• Over-the-counter products
• Herbal supplements (e.g., St John’s wort)

Practical interaction approach

• Make a list of your medicines and show it to the pharmacist when purchasing or starting Motilium.
• If you develop palpitations, fainting, or severe dizziness, stop and seek medical advice urgently.

Safety profile: who should be cautious

Most people take Motilium without serious problems, but like all medicines it can cause side effects. The safety profile is especially important because of possible effects on heart rhythm.

Common side effects

• Headache
• Dry mouth
• Stomach cramps or abdominal discomfort
• Diarrhoea or other gut changes
• Dizziness (uncommon but can occur)

Serious side effects (seek urgent advice)

Very rare but potentially serious concerns include changes to heart rhythm. Seek urgent medical advice if you experience:

• Fainting or near-fainting
• Fast or irregular heartbeat (palpitations), especially with dizziness
• Severe dizziness or breathlessness

When domperidone may not be suitable

Domperidone may be unsuitable or require extra caution if you have:

• Known heart rhythm problems or significant heart disease
• Low potassium or magnesium levels (for example, due to certain diuretics, vomiting/diarrhoea, or diet)
• Significant liver impairment
• Use of interacting medicines that increase domperidone exposure or affect QT interval

Pregnancy and breastfeeding

• If you are pregnant, ask a pharmacist or doctor for advice before using Motilium.
• If you are breastfeeding, discuss risks and benefits with a healthcare professional.

Tip: If you become pregnant or are planning pregnancy, review your treatment plan.

Practical use tips for best results

• Use the lowest effective dose for the shortest time needed.
• Take before meals if your symptoms are linked to eating.
• Avoid missed doses in the first days if you are trying to control symptoms.
• Check for interactions when you start a new medicine (including antibiotics and antifungals).
• Stay hydrated if you are prone to vomiting.
• If you have recurrent symptoms, consider medical review rather than repeated self-treatment.

Alternative options (depending on your symptoms)

If Motilium is not suitable or symptoms persist, there are other approaches for indigestion, nausea, and slow gastric emptying. Alternatives may include:

• Antacids and alginate-based treatments for heartburn/reflux symptoms
• Acid-suppressing medicines (e.g., proton pump inhibitors or H2 blockers) where appropriate for reflux-related symptoms
• Anti-nausea medicines (choices depend on cause and suitability)
• Prokinetic alternatives for selected cases of delayed gastric emptying (a clinician can advise)
• Non-medicine strategies such as smaller meals, avoiding late meals, and identifying trigger foods

Note: The best alternative depends on the underlying cause of your nausea or indigestion. If you’re unsure, a pharmacist can help you choose an appropriate option.
