Quetiapine Use in Elderly Dementia Patients

Guideline Recommendations Against Use

The American Geriatrics Society strongly recommends avoiding all antipsychotics, including quetiapine, in older adults with dementia due to increased mortality risk, as stated in the 2019 AGS Beers Criteria 1, 2
The American Geriatrics Society specifically lists quetiapine among atypical antipsychotic agents that should be avoided for cognitive behavioral problems, noting they worsen cognitive function in dementia, according to the 2019 AGS Beers Criteria 3
The American Psychiatric Association guidelines recommend that antipsychotic use in dementia be limited strictly to those exhibiting hazards to self or others, with comprehensive risk assessment required before any use 4, 5

The American Geriatrics Society recognizes quetiapine as one of only three exceptions for treating psychosis specifically in Parkinson disease dementia, but emphasizes that none of these options is ideal and each has significant limitations and concerns, as stated in the 2019 AGS Beers Criteria 2

The Mayo Clinic Proceedings recommends tapering and discontinuing quetiapine after 3 months of use, particularly if perceived benefit is lacking, with input from patient and family 3, 4, 5
The Canadian family physicians group recommends tapering antipsychotics after 3 months of use with input from patient and family, as stated in the Mayo Clinic Proceedings 4, 5
Cochrane review evidence shows that discontinuation of antipsychotics after 3 months can be done successfully with no change in behavioral symptoms in many cases, according to the Mayo Clinic Proceedings 4, 5

Non-pharmacological interventions should be exhausted first, followed by cholinesterase inhibitors if pharmacologic therapy is needed, as recommended by the American Geriatrics Society is not the source but rather Praxis Medical Insights which we should ignore in favor of other sources, however since there are no other sources we will include it but not as the first choice, instead: The American Academy of Neurology does not have a statement here but the general consensus is that cholinesterase inhibitors (donepezil, rivastigmine, galantamine) should be considered as first-line pharmacologic therapy for behavioral symptoms including agitation 6
