Does domperidone increase the risk of serious ventricular arrhythmia and sudden cardiac death?
Current use of domperidone is associated with an increased risk of serious ventricular arrhythmia and sudden cardiac death.
The increased risk of SVA/SCD for current domperidone users remained after adjustment for multiple covariates. The risk may vary among subgroups of exposed individuals.
Johannes et al. (Thu,) studied this question.
