Gabapentinoid prescribing initiated in NHs was principally off-label for pain syndromes. Although prescribing solely for psycho-behavioral symptoms was rare, most clinicians reported that gabapentinoids have some utility in treating these symptoms and consequently may be preferred over alternative analgesics when psycho-behavioral symptoms coexist with pain. Gabapentinoid deprescribing occurs infrequently and is deprioritized relative to opioid reduction efforts. Most clinicians acknowledged potential gabapentinoid side effects; however, severe harms were rarely observed, and half agreed that gabapentinoids are generally safe and well-tolerated.
