Metoclopramide-induced parkinsonism

Abstract

Metoclopramide hydrochloride (Reglan) is a widely prescribed drug for treatment of upper gastrointestinal symptoms. Although the drug is relatively safe, a growing body of literature has noted movement disorders after its administration. We have reported six cases of metoclopramide-induced parkinsonism seen in consultation over a two-year period. Five of these six patients had renal failure. Their parkinsonism improved on discontinuation of metoclopramide therapy. Metoclopramide-induced parkinsonism is not rare, and appropriate dose reduction in patients with renal failure will help reduce the incidence of this morbidity.
