Risperidone vs Aripiprazole for Dementia with Agitation

Evidence-Based Recommendation

• The American Academy of Family Physicians recommends risperidone at 0.5-2.0 mg/day for agitated dementia, starting at 0.25 mg daily at bedtime and titrating slowly 2, 1
• Risperidone has moderate-certainty evidence showing it probably reduces agitation slightly in dementia patients (SMD -0.21, 95% CI -0.30 to -0.12) 1

Critical Safety Considerations

• Antipsychotics should only be considered when symptoms are severe, dangerous, or causing significant distress, and non-pharmacological interventions have failed 1, 4
• The American College of Physicians recommends discussing risks and benefits with the patient and surrogate decision-makers before initiating treatment 1, 4

Practical Dosing Algorithm for Risperidone

• The American Academy of Family Physicians recommends starting risperidone at 0.25 mg once daily at bedtime and increasing by 0.25 mg increments every 5-7 days as tolerated 2, 1
• The target dose is 0.5-1.25 mg daily, and the maximum dose is 2 mg daily 2

Essential Non-Pharmacological Approaches

• The American Geriatrics Society recommends assessing and treating pain aggressively, and implementing environmental modifications and person-centered care plans before considering antipsychotics 1, 4
• The American Medical Directors Association recommends providing meaningful activities tailored to interests and abilities 1, 3
