Eye drop psychosis in parkinson’s disease: A cautionary tale

Abstract

Anticholinergic agents are used in a number of conditions ranging from overactive bladder and bradycardia to travel sickness but side-effects such as hallucinations, impaired memory and restlessness are increasingly recognised, though still under-reported in clinical practice. In Parkinson’s disease anticholinergics such as atropine are recommended by NICE for the management of excessive drooling. Dr Ferris et al. present such a case where commencing sublingual atropine drops caused a patient to develop hyperactive delirium and psychosis. They also discuss the subsequent clinical management steps.
