It works as an antiemetic by blocking D2-receptors at the chemoreceptor trigger zone and as a gastroprokinetic drug by blocking GI tract D2-receptors. According to research, using domperidone significantly raises the risk of cardiac arrhythmia and sudden cardiac death by 70%, most likely through prolonging the QT interval.

Hemolysis stimulates compensatory RBC production by boosting erythropoietin levels; however, this response is often insufficient to restore normal hemoglobin blood levels, resulting in anemia. It is a rare disease, with an annual incidence of one case in every 80 000 live births.
