Zopiclone is a drug that is used for the treatment of insomnia and other sleeping disorders. It reduces the amount of time needed to get to sleep and eliminates nocturnal awakenings throughout the night. It is also an effective sedative with muscle-relaxing properties. Zopiclone should ideally only be used short term to avoid issues with dependence or withdrawal symptoms - ideally for 4 weeks or less. Zopiclone is sold under various different brand names which include Zimovane, Datolan and Imovane.
