Delirium in someone on opioids often results from a combination of medication effects and reversible medical or environmental factors. The best approach is to adjust the opioid regimen to keep analgesia effective while reducing delirium risk. This means reviewing how the opioid is dosed and scheduled, and considering reducing the dose or rotating to a different opioid if cognitive symptoms emerge. At the same time, actively identify and treat delirium triggers such as dehydration, electrolyte imbalances, hypoxia, infections, constipation, urinary retention, poor sleep, or sensory deprivation. If agitation persists after optimizing the opioid plan and addressing triggers, using an antipsychotic cautiously can help, but benzodiazepines should not be first-line in delirium because they can worsen confusion and prolong delirium. Ignoring delirium is not appropriate; the goal is to preserve comfort and function by balancing pain control with cognitive safety.
