Estimating the number of sudden cardiac deaths attributable to the use of domperidone in France

Purpose The aim of this study was to estimate of the number of sudden cardiac deaths attributable to the use of domperidone in France in 2012 Methods Computation of the attributable fraction, function of the increase in risk of sudden cardiac death induced by domperidone and of the exposure prevalence. Multiplying the attributable fraction by the risk of sudden cardiac death in the French population gives an estimation of the number of sudden cardiac deaths attributable to domperidone. Results The use of domperidone in France is the cause of 231 deaths per year in the population aged 18 years or over. Conclusions This risk should be taken into consideration by clinicians when prescribing a drug which provides a minor benefit. Copyright © 2015 John Wiley & Sons, Ltd.
