Abstract: Proton pump inhibitors are used in the prevention and treatment of peptic ulcer, gastroesophageal reflux disease, gastritis, esophagitis. Chronic use of proton pump inhibitors causes various side effects. One of the life threatening side effects is hypomagnesemia, which may present in the form of arrhythmia, tetany, seizures and encephalopathy. We present the case of a 70 year old woman who presented with encephalopathy and parkinsonism due to hypomagnesemia. This case exemplifies that hypomagnesemia should be on the differential diagnosis among patients who present with metabolic encephalopathy with history of long term proton pump inhibitor consumption
