Earlier this year, the American Geriatrics Society updated the Beers Criteria for potentially inappropriate medication use in older adults. Non-benzodiazepine hypnotic sleep agents – such as those marketed under the brand names Lunesta® (eszopiclone), Ambien® (zolpidem) and Sonata® (zaleplon) – are not recommended for chronic use (considered longer than 90 days), and have been shown to have minimal improvements in sleep latency and duration. (1) This drug class has shown to improve sleep latency only up to 16 minutes and improve wake after sleep onset up to 25 minutes compared to placebo.(2,3)
With minimal evidence for efficacy, these agents are inappropriately used chronically – something that carries safety risks in older patients. These drugs may alter postural stability and equilibrium, leading to greater risk of falls and hip fractures. One study found the falling prevalence to be as high as 16.9 percent. (4) These high-risk injuries imply a significant number of fractures and consequential costs. (5) Trazodone and melatonin could be considered as safer alternatives for patients who have tried and failed to achieve success with non-pharmacological treatment recommendations.
Non-pharmacological sleep hygiene: first-line recommendations

- Do not go to bed hungry
- Avoid forcing sleep
- Avoid smoking, especially in the evening
- Adjust bedtime environment
- Exercise regularly for at least 20 minutes daily
