Sleep medications

medication Under review

Sleep medications are a broad group of prescription and over‑the‑counter drugs used to help people fall asleep faster, stay asleep longer, or improve overall sleep continuity. Major prescription classes include benzodiazepine hypnotics (such as temazepam), non‑benzodiazepine "Z‑drugs" that act on GABA-A receptors (such as zolpidem and eszopiclone), melatonin receptor agonists (such as ramelteon), low‑dose sedating antidepressants (such as doxepin), and dual orexin receptor antagonists (such as suvorexant, lemborexant, and daridorexant). Over‑the‑counter options commonly include sedating antihistamines like diphenhydramine and doxylamine, as well as melatonin supplements.

Research summary

AI-Generated Content: This summary was created by AI and may contain errors. Always verify with peer-reviewed sources.

Across healthy and otherwise uncomplicated adults with insomnia, randomized controlled trials and meta‑analyses show that many prescription sleep medications can modestly reduce sleep onset latency and increase total sleep time over short treatment periods of one to four weeks. Newer agents such as ramelteon, low‑dose doxepin, and dual orexin receptor antagonists have demonstrated sustained efficacy and generally acceptable safety in longer trials up to three to six months, including in older adults, with low rates of tolerance, rebound insomnia, or withdrawal symptoms upon discontinuation. In contrast, traditional benzodiazepine hypnotics and sedating antihistamines tend to provide smaller benefits on sleep while contributing to next‑day sedation, falls, cognitive impairment, and other adverse outcomes, particularly in older adults.
