One of the strongest sleeping pills on the market, Blue zopiclone is effective in treating insomnia. It is a member of a group of drugs called non-benzodiazepine hypnotics, which improve the brain’s ability to relax and sleep by enhancing the effects of gamma-aminobutyric acid (GABA). Because it may cause dependence and withdrawal symptoms, zopiclone is usually used for brief periods of time even if it is an effective medication. Long-term treatments for insomnia often include changing one’s lifestyle and undergoing behavioral therapy to address underlying causes. Always take zopiclone as prescribed, and speak with a doctor about the best course of action.
