The name of your medicine is Domperidone 1mg/ml Oral Suspension (called domperidone in this leaflet). The active ingredient in this medicine is called domperidone. This belongs to a group of medicines called ‘dopamine antagonists’.

This medicine is used to treat nausea (feeling sick) and vomiting (being sick) in adults and adolescents (12 years of age and older weighing 35 kg or more).

Do not take domperidone if:

    Signs of an allergic reaction include: a rash, swallowing or breathing problems, swelling of your lips, face, throat or tongue.
  • You have a tumour of the pituitary gland (prolactinoma).
  • You have a blockage or tear in your intestines.
  • You have black, tarry bowel motions (stools) or notice blood in your bowel motions.
    This could be a sign of bleeding in the stomach or intestines.
  • You have a moderate or severe liver disease.
  • Your ECG (electrocardiogram) shows a heart problem called “prolonged QT corrected interval”.
  • You have or had a problem where your heart cannot pump the blood round your body as well as it should (condition called heart failure).
  • You have a problem that gives you a low level of potassium or magnesium, or a high level of potassium in your blood.

Do not take domperidone if any of the above applies to you. If you are not sure, talk to your doctor or pharmacist before taking domperidone.

Warnings and precautions

Before taking this medicine contact your doctor if:

  • You suffer from liver problems (liver function impairment or failure) (see “Do not take domperidone if”)
  • You suffer from kidney problems (kidney function impairment or failure). It is advisable to ask your doctor for advice in case of prolonged treatment as you may need to take a lower dose or take this medicine less often, and your doctor may want to examine you regularly.

If you are not sure if any of the above apply to you, talk to your doctor or pharmacist before taking domperidone. Do this even if they have applied in the past.

Domperidone may be associated with an increased risk of heart rhythm disorder and cardiac arrest.

This risk may be more likely in those over 60 years old or taking doses higher than 30mg per day.

The risk also increases when domperidone is given together with some drugs. Tell your doctor or pharmacist if you are taking drugs to treat infection (fungal infections or bacterial infection) and/or if you have heart problems or AIDS/HIV (see “Other medicines and domperidone”).

Domperidone should be used at the lowest effective dose.

While taking domperidone, contact your doctor if you experience heart rhythm disorders such as palpitations, trouble breathing, loss of consciousness. Treatment with domperidone should be stopped.

Adolescents weighing less than 35 kg and children

Domperidone should not be given to adolescents 12 years of age and older weighing less than 35 kg, or in any children less than 12 years of age, as it is not effective in these age groups.

Other medicines and domperidone:

Tell your doctor or pharmacist if you are taking or have recently taken any other medicines. This includes medicines you can buy without a prescription, including herbal medicines. This is because domperidone can affect the way some other medicines work. Also, some medicines can affect the way domperidone works.

Do not take Domperidone Oral Suspension if you are taking medicine to treat:

  • Fungal infections such as azole anti-fungals, specifically oral ketoconazole, fluconazole or voriconazole.
  • Bacterial infections, specifically erythromycin, clarithromycin, telithromycin, moxifloxacin, pentamidine (these are antibiotics)
  • Heart problems or high blood pressure (e.g., amiodarone, dronedarone, quinidine, disopyramide, dofetilide, sotalol, diltiazem, verapamil)
  • Psychoses (e.g., haloperidol, pimozide, sertindole)
  • Depression (e.g., citalopram, escitalopram)

Tell your doctor or pharmacist if you are taking drugs to treat infection, heart problems, AIDS/HIV or Parkinson’s disease.

Tell your doctor if you are taking antacids or other medicines that reduce stomach acid (such as cimetidine or sodium bicarbonate). These medicines can be taken if you are also taking domperidone but they should not be taken at the same time as they may affect how well domperidone works.

Medicines that reduce stomach acid should be taken after a meal.

Domperidone and apomorphine

Before you use domperidone and apomorphine, your doctor will ensure that you tolerate both medicines when used simultaneously. Ask your doctor or specialist for a personalised advice. Please refer to the apomorphine leaflet.
