Benzodiazepines and zopiclone are used frequently and for extended periods to aid sleep, despite well-recognised harms of dependency, cognitive decline and falls.1

What’s more, sedative-hypnotics are not very effective for managing insomnia in older adults – while 13 people need to be treated for one person to have improved sleep quality, only six people need to be treated for one of them to experience harm.2

In Aotearoa, approximately 347,000 people (9.1% of the enrolled population aged ≥18) were dispensed a benzodiazepine or zopiclone in the last year, and more than half of those aged ≥80 received 90 tablets or more.3
