Opioid-induced delirium should be managed by optimizing the opioid regimen and addressing treatable triggers, not by simply increasing sedation. The best approach is to review how the patient is being dosed and scheduled: consider reducing the total daily opioid amount if possible, switching to a different opioid, or using a shorter-acting agent. These changes can lessen cognitive disruption while still maintaining pain relief. If agitation or delirium persists after optimizing the opioid, antipsychotics may be used cautiously, but they come with risks and should not be relied on as a first-line solution. Equally important is actively treating delirium triggers such as infections, dehydration, electrolyte imbalances, urinary retention, constipation, or other reversible contributors. This strategy targets the underlying cause of delirium and reduces sedation, rather than compounding it by increasing opioid doses. In contrast, increasing opioid dose tends to worsen delirium and sedation, benzodiazepines are not preferred as first-line delirium management due to potential to worsen cognitive impairment, and ignoring delirium is inappropriate because it can lead to worse outcomes and distress.
