Zopiclone is a prescription-only medication commonly used for the short-term treatment of insomnia. It belongs to a class of medicines known as non-benzodiazepine hypnotics, which work by calming brain activity to help you fall asleep faster and stay asleep longer. Zopiclone is generally prescribed when sleep problems cause significant distress or daytime fatigue. It should only be taken under medical supervision, as misuse or prolonged use may lead to dependence, tolerance, or unwanted side effects.
