It can also be used to treat stomach pain if you're having end of life care (palliative care).
Domperidone 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 comes as tablets or as a liquid that you swallow. It is available on prescription only.
It is also known by the brand name Motilium.

3. Who can and cannot take domperidone

4. How and when to take it
Always follow a doctor's instructions when taking domperidone.
Take it when you need it to help with your symptoms.
It's best to have domperidone before food. Take it 15 to 30 minutes before you have a meal or snack.
Tablets: take the tablet whole with a drink of water. Do not crush or chew it.
Liquid: the medicine comes with an oral 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 give you the right amount.
The usual dose for adults and children aged 12 years and older is one 10mg tablet (or 10ml of liquid).
You can take domperidone up to 3 times a day, if you need it. Space doses evenly throughout the day, at least 8 hours apart.
If you forget to take it
If you forget to take domperidone, take it as soon as you remember. If it's almost time for your next dose, 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 accidentally take more than your prescribed dose, you may get a fast or irregular heartbeat.
If you need to go to A&E, do not drive yourself. Get someone else to drive you or call for an ambulance.
Take the domperidone packet, or the leaflet inside it, plus any remaining medicine with you.

Domperidone and breastfeeding
Domperidone is not usually recommended when breastfeeding, as it passes into breast milk in small amounts. Talk to a doctor, as other medicines might be better.
If your baby was premature, had a low birth weight or has health problems, speak to a doctor before taking any anti-sickness medicine.
Domperidone is sometimes used to increase milk supply. However, there is some evidence that it can give a baby an irregular heartbeat. Talk to a doctor about the benefits and possible risks of taking domperidone when breastfeeding.
If you take domperidone while breastfeeding and you notice anything unusual with your baby, such as sleeping more than usual, talk to a health visitor or doctor as soon as possible.
