20 Benzodiazepines l Delirium due to alcohol withdrawal l For all other causes, not first-line therapy  More likely cause disinhibition, particularly in elderly l Low dose with antipsychotic medications may be synergistic l Delirium due to alcohol withdrawal l For all other causes, not first-line therapy  More likely cause disinhibition, particularly in elderly l Low dose with antipsychotic medications may be synergistic

21 Reassess regularly l Monitor carefully l If negligible or partial response  Re-evaluate diagnosis  Inquire about adherence to medication  Consider dosage adjustment  Consider a different medication  Refer to a specialist l Monitor carefully l If negligible or partial response  Re-evaluate diagnosis  Inquire about adherence to medication  Consider dosage adjustment  Consider a different medication  Refer to a specialist

22 Terminal delirium l Delirium during the dying process o Signs of the dying process o Agitation, restlessness o Moaning, groaning l Multiple causes, irreversible l Lorazepam or midazolam to settle l Sedating antipsychotics Breitbart W, Strout D.
