Experiences with
DomperidoneDomperidone is an anti-sickness medicine. It helps you to stop feeling or being sick (nausea or vomiting).
It works by causing the muscles at the top of your stomach to tighten and the muscles at the bottom of your stomach to relax. This makes you less likely to be sick (vomit).
Domperidone can also be used to treat stomach pain if you're having end of life care (palliative care).
It is sometimes used to increase milk supply. Your doctor may prescribe it if you're having trouble breastfeeding but only if other things have not worked.
Domperidone is available on prescription only. It comes as tablets or as a liquid that you swallow.
Who can take domperidone
Most adults, and children aged 12 years old and over, can take domperidone.
It's sometimes prescribed for babies and younger children by a specialist doctor.
Who may not be able to take domperidone
Domperidone is not suitable for some people.
To make sure it's safe for you, tell your doctor or pharmacist before taking this medicine if you:
- have ever had an allergic reaction to domperidone or any other medicine
- weigh less than 35kg
- have a condition that can cause a blockage in your bowel, such as Crohn's disease or diverticulitis
- have ever had bleeding from your stomach or gut
- have a tumour on your pituitary gland
- have liver, kidney or heart problems, or an irregular heartbeat (arrhythmia)
Domperidone may not be suitable for people over 60 years old. This is because there's more risk of side effects.
Dosage
Domperidone comes as tablets and a liquid that you swallow.
The usual dose for adults and children aged 12 years old and older is one 10mg tablet (or 10ml of liquid), up to 3 times a day.
How to take it
Swallow your tablet whole with a drink of water. Do not crush or chew it.
Domperidone liquid comes with an oral plastic syringe to help you measure your dose. If you do not have a syringe, ask a pharmacist for one. Do not use a kitchen teaspoon, as this will not measure the right amount.
You can take domperidone up to 3 times a day, but only take it when you need it. Leave 8 hours between each dose you take.
It's best to take domperidone before food. Take it 15 to 30 minutes before you have a meal or snack.
How long to take it for
You'll usually take domperidone for up to 1 week. This is because it can cause an irregular heartbeat (arrhythmia) if you take it for longer or at a high dose.
Your doctor will tell you how long to take it for. They'll recommend that you take it for the shortest possible time and at the lowest dose that works for you.
If you forget to take it
If you forget to take domperidone, take it as soon as you remember, as long as this is at least 2 hours before your next dose is due. If it is less than 2 hours before your next dose is due, skip the missed dose and take the next one at the usual time.
Never take 2 doses at the same time. Do not take a double dose to make up for a forgotten dose.
If you take too much
Taking too much domperidone can be dangerous.
If you take more than your prescribed dose, you may get a fast or irregular heartbeat.

If this happens, try chewing sugar-free gum or sucking a sugar-free sweet.

Domperidone and pregnancy
Domperidone can be taken in pregnancy if other anti-sickness medicines have not worked.
Domperidone and breastfeeding
If your doctor or health visitor says your baby is healthy, you can take domperidone while breastfeeding but it's best to only take it for a short time.
There is not much information about how much domperidone passes into breast milk, but it's only a tiny amount. It's been used during breastfeeding for many years without babies having side effects.
Domperidone can also be used to help increase your breast milk supply. Although it's not made for this purpose, a specialist may offer this to you, if other things have not worked.
If you notice your baby has diarrhoea, or you have any other concerns about your baby, talk to a midwife, health visitor, pharmacist or doctor as soon as possible.
Domperidone and fertility
There's no evidence to suggest that taking domperidone affects fertility in either men or women.

Some medicines and domperidone can affect each other. This may increase your chance of having side effects.
Tell your doctor or pharmacist if you're taking:
- antidepressants or antipsychotic medicines
- antibiotics or medicines for fungal infections
- medicines for malaria
- medicines for HIV infection
- medicines for a heart condition or high blood pressure
- medicines for cancer, or if you're having treatment for cancer
Taking domperidone with other anti-sickness medicines
It's usually best to only take 1 type of medicine for feeling or being sick.
If domperidone does not work for you, speak to a doctor. They may want to recommend a different medicine.
Mixing domperidone with herbal remedies and supplements
Some herbal remedies can make your side effects worse.
There's not enough information to say that other complementary medicines and herbal remedies are safe to take with domperidone. They're not tested in the same way as pharmacy and prescription medicines. They're generally not tested for the effect they have on other medicines.
