Drug-Induced Parkinsonism: Clinical Perspective and Management Approach

Drug-induced parkinsonism (DIP) is a common adverse effect of dopamine receptor-blocking agents that mimics idiopathic Parkinson's disease but requires prior exposure to triggering medications for diagnosis. Management involves discontinuing or reducing the offending agent, considering alternative medications with lower DIP risk, and using L-dopa when necessary, with ancillary testing like DaT scans helping distinguish DIP from prodromal Parkinson's disease.
