Delirium management hinges on avoiding medications that worsen cognitive disturbance. Benzodiazepines are particularly avoided because they are powerful central nervous system depressants. They dull arousal and attention, can provoke confusion and agitation in some patients (paradoxical reactions), and often prolong the delirium rather than resolve it. This makes it harder to assess symptoms, can deepen sleep-wake disturbances, and increases risks like respiratory depression and falls in vulnerable patients. In palliative care, they’re reserved for specific situations such as alcohol or benzodiazepine withdrawal or when agitation is refractory and other options have been tried, with careful dosing and monitoring. While other drug classes can also contribute to delirium, the classic concern with this one is its potential to worsen delirium through CNS depression and cognitive impairment.
