What Is Lunesta?
Eszopiclone (brand name Lunesta) is a non-benzodiazepine hypnotic (Z-Drug) prescribed for insomnia, and other psychiatric conditions. Only Z-drug without FDA short-term use restriction (can be prescribed long-term). Longer half-life than zolpidem — better for sleep maintenance. Unpleasant metallic taste is the most common complaint. Schedule IV controlled substance.
At Psychiatry Telemed, eszopiclone is prescribed and monitored by board-certified psychiatrists who understand the nuances of Z-Drug pharmacology — selecting the right dose, managing side effects, monitoring drug interactions, and optimizing your treatment through consistent monthly medication management appointments.

How Lunesta Affects Neurotransmitters
How Lunesta Works
Eszopiclone binds GABA-A receptors with activity at both alpha-1 (sedation) and alpha-2/3 (anxiolytic) subunits, providing sleep-inducing effects plus mild anxiolysis. This broader binding may explain its effectiveness for both sleep onset and sleep maintenance.
