A 2018 Cochrane review found that it produced moderate improvement in sleep onset and maintenance. The authors suggest that where preferred non-pharmacological treatment strategies have been exhausted,<unk>  provides an efficient treatment for insomnia. In 2014, the USFDA asked that the starting dose be lowered from 2 milligrams to 1 milligram after it was observed in a study that even 8 hours after taking the drug at night, some people were not able to cope with their next-day activities like driving and other activities that require full alertness.<unk>  is slightly effective in the treatment of insomnia where difficulty in falling asleep is the primary complaint. Kirsch et al. found the benefit over placebo to be of questionable clinical significance. Although the drug effect and the placebo response were rather small and of questionable clinical importance, the two together produce a reasonably large clinical response. It is not recommended for chronic use in the elderly. Elderly Sedative hypnotic drugs including<unk>  are more commonly prescribed to the elderly than to younger patients despite benefits of medication being generally unimpressive. Care should be taken in choosing an appropriate hypnotic drug and if drug therapy is initiated it should be initiated at the lowest possible dose to minimise side effects. In 2015, the American Geriatrics Society reviewed the safety information about<unk>  and similar drugs and concluded that the "nonbenzodiazepine, benzodiazepine receptor agonist hypnotics<unk> , zaleplon, zolpidem) are to be avoided without consideration of duration of use because of their association with harms balanced with their minimal efficacy in treating insomnia." The review made this determination both because of the relatively large dangers to elderly individuals from zolpidem and other "z-drugs" together with the fact the drugs have "minimal efficacy in treating insomnia." This was a change from the 2012 AGS recommendation, which suggested limiting use to 90 days or less. The review stated: "the 90‐day‐use caveat was removed from nonbenzodiazepine, benzodiazepine receptor agonist hypnotics, resulting in an unambiguous 'avoid' statement (without caveats) because of the increase in the evidence of harm in this area since the 2012 update." An extensive review of the medical literature regarding the management of insomnia and the elderly found that there is considerable evidence of the effectiveness and durability of non-drug treatments for insomnia in adults of all ages and that these interventions are underutilized. Compared with the benzodiazepines, the nonbenzodiazepine sedative-hypnotics, including<unk>  appeared to offer few, if any, significant clinical advantages in efficacy or tolerability in elderly persons. It was found that newer agents with novel mechanisms of action and improved safety profiles, such as the melatonin receptor agonists, hold promise for the management of chronic insomnia in elderly people. Long-term use of sedative-hypnotics for insomnia lacks an evidence base and has traditionally been discouraged for reasons that include concerns about such potential adverse drug effects as cognitive impairment (anterograde amnesia), daytime sedation, motor incoordination, and increased risk of motor vehicle accidents and falls. In addition, the effectiveness and safety of long-term use of these agents remain to be determined. It was concluded that more research is needed to evaluate the long-term effects of treatment and the most appropriate management strategy for elderly persons with chronic insomnia. A 2009 meta-analysis found a higher rate of infections.
