Management of Agitation in Elderly Patients on Comfort Measures
First-Line Pharmacological Management
- The American College of Physicians recommends haloperidol 0.5-1 mg orally at night and every 2 hours as needed for agitation in elderly patients on comfort measures, with consideration of adding lorazepam if agitation persists despite adequate haloperidol dosing 1, 2
- Haloperidol is the preferred first-line agent for delirium with agitation in patients on comfort measures, with a starting dose of 0.5-1 mg orally at night and every 2 hours when required, and a maximum dose of 5 mg daily in elderly patients 1, 2
- Alternative antipsychotic options if haloperidol is not effective or tolerated include risperidone 0.5-1 mg twice daily, olanzapine 2.5-15 mg daily, and quetiapine 50-100 mg PO twice daily 3, 4
Benzodiazepines
- Lorazepam 0.5-1 mg orally four times a day as required, with a maximum of 4 mg in 24 hours, can be added if agitation is refractory to antipsychotics, and the dose should be reduced to 0.25-0.5 mg in elderly patients, with a maximum of 2 mg in 24 hours 1, 2
Non-Pharmacological Interventions
- Addressing reversible causes of agitation, such as exploring patient's concerns and anxieties, ensuring effective communication and orientation, providing adequate lighting, treating underlying causes, and orienting the patient with family presence, is recommended 1, 2, 3
Monitoring and Dose Adjustment
- The National Comprehensive Cancer Network recommends titrating the starting dose to optimal effect, monitoring for symptom control, and adjusting medication as needed, with consideration of scheduled dosing if needed frequently, and decreasing doses if hepatic or renal failure is present 1, 3
Important Considerations and Cautions
- The American Society of Clinical Oncology recommends monitoring for extrapyramidal symptoms with haloperidol, and being aware of the potential side effects of atypical antipsychotics, such as sedation, orthostatic hypotension, and metabolic effects 4, 5
- The use of benzodiazepines should be cautious, with consideration of the increased risk of falls, paradoxical agitation, and the need for lower doses in frail elderly patients 4
