Eszopiclone is part of a class of medications called sedative/hypnotics, which are known more commonly as sleep medicines. Like many other sleep medications, it is a controlled substance and may be abused.
Eszopiclone has been evaluated in several clinical studies for insomnia. In studies for chronic insomnia, people who took eszopiclone fell asleep faster and stayed asleep longer than people who did not take it. Similar results were seen in a study of eszopiclone in people with transient insomnia (insomnia that comes and goes).
Also, studies have shown that the medication can cause mild rebound insomnia (worsening of insomnia after stopping a medication). Rebound insomnia symptoms usually occurred for only one night after eszopiclone was stopped, after which people returned to their normal sleeping patterns.
