The analysis included individuals aged 18 or above who were prescribed gabapentinoids and had an incident all-cause drug poisoning event between 1st January 2010 and 31st December 2020. Using the self-controlled case series (SCCS) design, we assessed the risk of drug poisoning incidence in predefined risk periods: 90 days before treatment initiation, first 28, 29-56, 57-84 days, and the remaining treatment time. Concomitant use with opioids/benzodiazepines was also evaluated. Adjusted incidence rate ratios (aIRRs) were calculated using conditional Poisson regression.
