Gabapentin Use in Geriatric Patients with Dementia

Critical Safety Concerns

• The American Geriatrics Society explicitly recommends avoiding concurrent use of opioids with gabapentinoids, as this combination increases risk of respiratory depression and death in older adults, with a particular emphasis on elderly patients with dementia 1
• The concurrent use of three or more CNS-active drugs, including gabapentin combined with antidepressants, antipsychotics, benzodiazepines, or other antiepileptics, significantly increases fall risk and should be avoided whenever possible in elderly patients with dementia 1, 2

Practical Prescribing Algorithm

• The American Geriatrics Society recommends documenting all current CNS-active medications and discontinuing or minimizing these before adding gabapentin, and ensuring the patient is not taking opioids concurrently, to minimize the risk of adverse interactions in elderly patients with dementia 1, 2
• The Mayo Clinic Proceedings suggests reassessing the need for gabapentin continuation every 3 months, attempting dose reduction or discontinuation if behavioral symptoms have stabilized, to minimize the risk of long-term adverse effects in elderly patients with dementia 3

Critical Pitfalls to Avoid

• The American Geriatrics Society warns against combining gabapentin with opioids in elderly dementia patients due to synergistic respiratory depression risk, emphasizing the need for careful prescribing practices to minimize the risk of adverse outcomes 1
