Key Message
Comparative evidence supports that droperidol is as effective as haloperidol and olanzapine for the sedation of adult patients with uncontrolled aggression, anxiety, or violent behaviour in acute care settings, and a limited quantity of evidence supports the superiority of droperidol over ziprasidone and lorazepam monotherapies. There are no statistically significant differences in adverse event frequency or severity in adult patients treated with droperidol compared with haloperidol or olanzapine. Guidelines published in 2015 support the safety and efficacy of droperidol treatment for agitation based on high-quality relevant evidence. These guidelines found insufficient evidence to support electrocardiogram or telemetry monitoring of patients who were administered less than 2.5 mg of droperidol.
