Public Communication – Health Canada Endorsed Important Safety Information on domperidone maleate

March 7, 2012

Subject: Association of domperidone maleate with serious abnormal heart rhythms and sudden death (cardiac arrest)

The manufacturers of domperidone, in collaboration with Health Canada, would like to inform you of new safety information for domperidone.

Domperidone is a medication used to treat symptoms of slowed stomach emptying caused by some stomach and intestine problems (such as gastritis or gastroparesis). Domperidone is also used to prevent symptoms such as nausea and vomiting caused by some drugs used to treat Parkinson's disease.

It is important to be aware of the following information:

  • The risk of serious abnormal heart rhythms or sudden death (cardiac arrest) may be higher in patients taking domperidone at doses greater than 30 mg a day, or in patients who are more than 60 years old, based on results from recent studies.
  • Domperidone should be used at the lowest possible dose that is right for you, including if you are suffering from Parkinson's disease.
  • If you have:
    • a heart condition with abnormal electrical activity of your heart (especially a condition called QT prolongation) or
    • a heart condition such as heart failure or
    • low blood levels of potassium or magnesium,

    domperidone should be used with caution when taken together with other drugs that can change the electrical activity of the heart.

Changes to the electrical activity of your heart (called QT interval prolongation and seen on the electrocardiogram [ECG]) can lead to serious abnormal heart rhythms. These abnormal heart rhythms can be life-threatening.

More detailed information about the recent studies on domperidone and the risk of serious abnormal heart rhythms and sudden death (cardiac arrest) can be found in a related communication for healthcare professionals.

If you experience any symptoms of abnormal heart rhythms such as heart palpitations, dizziness, fainting, or seizures while you are taking domperidone, you should stop taking domperidone and get medical attention right away.

Before starting treatment with domperidone, you should tell your healthcare professional if you have had any heart problems, if you are taking other medications including medications without a prescription or natural health products, and if you have had low blood levels of potassium or magnesium.

If you are already taking domperidone, you should talk to your healthcare professional to find out if you are taking the correct dose for you. Contact your healthcare professional before stopping or changing your dose of domperidone.

Domperidone is also called domperidone maleate, or:

  • Apo-domperidone
  • Ava-domperidone
  • Dom-domperidone
  • Jamp-domperidone
  • Mylan-domperidone
  • Nu-domperidone
  • PHL-domperidone
  • PMS-domperidone
  • Domperidone-10
  • RAN-domperidone
  • Domperidone
  • Teva-domperidone
  • Ratio-domperidone

The manufacturers of domperidone products are working with Health Canada to include this new safety information about serious abnormal heart rhythms and sudden death (cardiac arrest), as well as the new dosing information, in the Canadian Product Monographs for domperidone.

These Canadian Product Monographs are reference documents for healthcare professionals prescribing domperidone. They can be found in the Drug Product Database on the Health Canada Web site, or by contacting the manufacturers listed in the box below.

Managing marketed health product-related adverse reactions depends on healthcare professionals and consumers reporting them. Any case of serious abnormal heart rhythms or sudden death (cardiac arrest) or other serious or unexpected adverse reactions in patients receiving domperidone should be reported to the manufacturer (see the list below) or Health Canada.
