Assessment of the neuroleptic malignant syndrome was carried out by using the Naranjo Algorithm Probability Scale which resulted in a highly probable reaction to haloperidol. The difficulties in establishing the diagnosis in this patient lead to late intervention resulting in a slow recovery and prolonged hospitalization. Our objective in this presentation is to highlight the importance of early recognition of this potentially fatal adverse drug reaction.
