1. At a glance: data sheet

Metoclopramide (MCP for short, best-known brand name Paspertin®) is a medicine for nausea and vomiting. As a so-called prokinetic, it also stimulates stomach movement and speeds up gastric emptying. Because of the risk of movement disorders, it may only be used short-term – for a maximum of 5 days.

2. How metoclopramide works

Nausea and vomiting are controlled in the brain by a "vomiting centre". An important messenger substance here is dopamine. Metoclopramide blocks certain dopamine docking sites (receptors) in this area – this dampens the urge to vomit and the nausea subsides, the vomiting eases.

At the same time, MCP acts in the upper digestive tract: it tightens the transition from the oesophagus to the stomach, stimulates stomach movement and thereby speeds up gastric emptying towards the intestine. That is why it also helps with a sluggish, overly full feeling in the stomach and with stomach pain linked to disturbed gastric emptying. It is used, among other things, for acute nausea, in the context of a gastrointestinal infection and as an accompaniment to migraine, where it relieves nausea and improves the absorption of painkillers.

3. Use & dosage

The usual single dose for adults is 10 mg, up to three times daily – ideally about half an hour before meals. The maximum daily dose is 30 mg and should not exceed 0.5 mg per kilogram of body weight. In adolescents and children from the appropriate age, the dose is strictly based on body weight.

Group / situationDosage
Adults (standard)3× 10 mg/day, max. 30 mg/day
Adolescents (15–19 yrs)10 mg up to 3×/day by body weight
Children from 1 year0.1–0.15 mg/kg up to 3×/day, only on medical instruction
Impaired kidney functionReduce dose (to be set by a doctor)
Duration of use (all)Maximum 5 days
Table scrollable to the right
Dosage by weight – especially in children In children and adolescents, body weight alone determines the dose, not age. Metoclopramide is not approved for children under 1 year and is generally used only cautiously, because movement disorders occur more frequently here. Follow the medical instructions exactly and never measure drops "by feel".

A missed dose is not made up for by a double amount. Simply take the next dose at the usual time. What generally applies to a missed dose is explained in the guide Forgotten medication.

4. Why a maximum of 5 days?

The European Medicines Agency (EMA) has significantly restricted the use of metoclopramide with a Red Hand Letter: MCP may now only be used short-term – for a maximum of 5 days. The reason is the risk of neurological side effects, above all uncontrolled movements (dyskinesias). These occur more frequently the higher the dose and the longer the use.

Metoclopramide is therefore a medicine for acute, temporary nausea – not a long-term therapy. If the symptoms persist after 5 days, that is no reason to simply carry on, but rather a reason to have the cause investigated by a doctor.

5 days is the maximum, not the goal Take MCP only for as long as it is really necessary, and never for longer than 5 days in a row. Even a renewed "course" shortly after the last one should always be discussed with a doctor.

5. Side effects & movement disorders

Common are harmless complaints such as tiredness, diarrhoea or a feeling of weakness. The most important and name-giving danger, however, are movement disorders (extrapyramidal disorders): uncontrolled, often frightening movements of the face, tongue, neck or limbs. They can occur as early as after the first dose – especially in children, adolescents and young adults.

Side effectFrequencyWhat to do?
Tiredness, drowsinessCommonDo not drive if you feel dazed
DiarrhoeaCommonMake sure to drink enough fluids
Restlessness, urge to moveOccasionalRaise with a doctor
Uncontrolled movements (face, tongue, limbs), oculogyric crises, muscle crampsOccasional to rareStop taking it – see a doctor immediately
Table scrollable to the right
Warning signs of a movement disorder – stop taking it and see a doctor immediately Uncontrolled movements or cramping of the face, tongue, jaw or neck, twisted oculogyric crises (the eyes can no longer be controlled), muscle cramps or a sudden strong inner restlessness. Stop metoclopramide immediately and seek medical help. These symptoms usually subside after stopping.

6. Interactions

Metoclopramide speeds up gastric emptying and can thereby influence how quickly other medicines are absorbed. It also enhances the sedating and dopamine-active effects of other agents. Check combinations in the interaction check.

Metoclopramide + neuroleptics & Parkinson's medicines Together with other dopamine blockers (e.g. certain neuroleptics), the risk of severe movement disorders increases significantly. With Parkinson's medicines, MCP can conversely cancel out their effect. Both combinations absolutely belong in medical hands.
Substance / medicineInteractionRecommendation
Neuroleptics, other dopamine blockersEnhanced movement disordersDo not combine without medical instruction
Parkinson's medicines (e.g. levodopa)Mutual weakening of effectOnly under medical coordination
Sedatives, alcohol, opioidsEnhanced tirednessAvoid; do not drive
Anti-diarrhoeal agents such as loperamideOpposing effect on the intestineHave the combination checked by a doctor

7. Alternatives & special groups

Not every case of nausea needs metoclopramide. For mild complaints, rest, small sips of fluid and easily digestible food are often enough. If that is not sufficient, there are other antiemetics depending on the cause – the practice makes the choice. In the case of a gastrointestinal infection, replacing fluids and salts is the priority.

Particular caution applies to children and adolescents as well as older people: in these groups, movement disorders and dazedness occur more frequently. In older people, the dose is often chosen more cautiously, and it is likewise reduced with impaired kidney or liver function. During pregnancy and breastfeeding, a medical case-by-case decision is necessary.

FAQ: Frequently asked questions about metoclopramide

MCP drops (metoclopramide) are used against acute nausea and vomiting, for example with gastrointestinal infections or as an accompaniment to migraine. As a prokinetic, they also stimulate gastric emptying. They require a prescription and may only be used short-term, for a maximum of 5 days.
The European Medicines Agency has limited use to a maximum of 5 days via a Red Hand Letter. The reason is the risk of neurological side effects, above all uncontrolled movements. These occur more frequently the higher the dose and the longer the use. If symptoms persist, have the cause investigated by a doctor.
As drops, metoclopramide is absorbed rapidly, and the effect usually sets in within about 15 to 30 minutes. It is best to take MCP around half an hour before meals. If it has no effect at all after a short time, do not increase the dose on your own, but speak with the practice.
If uncontrolled movements of the face, tongue or limbs, muscle cramps or oculogyric crises occur, stop taking it immediately and seek medical help. These extrapyramidal disorders can occur as early as after the first dose, but usually subside again after stopping.
Only cautiously and exclusively on medical instruction. Metoclopramide is not approved for children under 1 year, because movement disorders are more common in children and adolescents. The dose is strictly based on body weight. Never measure drops by feel, but exactly as specified.
Yes, tiredness and drowsiness are among the common side effects. Together with alcohol, sedatives or painkillers, the dazedness can be intensified. Do not drive and do not operate machinery if you feel dazed. In older people this effect is often more pronounced.
With migraine, metoclopramide is used mainly against the accompanying nausea. In addition, it improves gastric emptying, so that painkillers can be absorbed better. However, it does not replace a targeted migraine therapy. You can find more on this in the article on migraine. Here too, the 5-day limit applies.
