Eszopiclone, sold under the brand name Lunesta among others, is a medication used in the treatment of insomnia.[3][4] Evidence supports slight to moderate benefit up to six months.[5][4][6] It is taken by mouth.[3][5]

Common side effects include headache, dry mouth, nausea, and dizziness.[5] Severe side effects may include suicidal thoughts, hallucinations, and angioedema.[5] Rapid decreasing of the dose may result in withdrawal.[5] Eszopiclone is classified as a nonbenzodiazepine or Z-drug and a sedative and hypnotic of the cyclopyrrolone group.[7] It is the S-stereoisomer of zopiclone.[5][8] It works by interacting with the GABA receptors.[7]

Approved for medical use in the United States in 2004,[3] eszopiclone is available as a generic medication.[5] In 2020, it was the 232nd most commonly prescribed medication in the United States, with more than 1 million prescriptions.[9][10] Eszopiclone is not sold in the European Union; as of 2009, the European Medicines Agency (EMA) ruled that it was too similar to zopiclone to be considered a new active substance.[11][12][13]
