• Objective To identify temporal trajectories of anxiolytic benzodiazepine (A‐BZD) use over 10 years among new A‐BZD users aged 50 and older and describe treatment patterns and demographic and clinical characteristics associated with each trajectory. Method A representative cohort of the French national health insurance fund users was tracked from 2006 through 2015. We used latent class mixed models to identify the trajectories. Results We observed four trajectories among new users (no A‐BZD dispensing in 2005) plus one non‐use trajectory. The proportion of occasional use among users was 60%; early increasing use, 10%; late increasing use, 17%; and increasing/decreasing use, 13%. Prevalence of occasional use decreased with age in women, but not men. Duration of treatment episodes and doses differed between trajectories. Multiple regression analyses with occasional use as the reference showed that the other three trajectories shared characteristics (age, coprescriptions of other psychotropic drugs, and more general practitioner consultations) but differed by the presence at inclusion or occurrence during follow‐up of psychiatric, neurodegenerative, and somatic conditions. Conclusion We found four different long‐term temporal trajectories in new A‐BZD users (occasional, early increasing, late increasing, and increasing/decreasing use). Difficulties quitting or reducing consumption may be very different for each trajectory, requiring tailored care approaches.
