 Results from a survey including 2811 community-dwelling older adults 65 years and over showed that 32 of the respondents consumed BZD for an average of 205 days and 60 of them had at least received one potentially inappropriate prescription during this period e.g. a prescription of a BZD with a long half-life or a prescription of 2 BZD for more than 6 consecutive weeks, etc.. Another study showed that 45 of new BZD users take these drugs for more than 30 days. It should be noted that the definition of a long-term BZD use varies from three to four months of consumption, which corresponds to the average period used by almost all seniors.
