Eszopiclone, commonly known by the brand name Lunesta, is a medication prescribed to treat insomnia.

Always consult your healthcare provider if you experience any concerning symptoms or if you have any questions about the use of Eszopiclone. This ensures that you can manage your insomnia safely and effectively.
