Zopiclone is a medication used to treat a sleeping problem called insomnia. Zopiclone is a sleeping pill that belongs to a group of drugs called non-benzodiazepine hypnotics. It has a different structure to benzodiazepine sedative hypnotics, such as Halcion (triazolam), but has similar benefits and side effects.

Zopiclone helps to reduce the amount of time it takes you to fall asleep (sleep latency), increase the amount of time you sleep for (sleep duration), and decrease the number of times you wake up at night (nocturnal awakenings). Zopiclone starts to work quickly, taking about an hour to work.
