Hypersensitivity
Eszopiclone is an S-enantiomer of zopiclone; a nonbenzodiazepine hypnotic of the cyclopyrrolone class. It is structurally unrelated to pyrazolopyrimidines, imidazopyridines, benzodiazepines, barbiturates, or other known drugs with similar hypnotic activity. The exact mechanism of action is unknown, its effect is associated with the interaction with gamma-aminobutyric acid (GABA)-receptor complex at binding domains found near to or allosterically coupled to benzodiazepine receptors.
Initiate treatment only after careful evaluation of patients; failure of insomnia to remit after 7-10 days of treatment may indicate presence of primary psychiatric and/or medical illness requiring evaluation. May be associated with abnormal thoughts and behaviour changes e.g. bizarre behavior, agitation, hallucinations, depersonalization, decreased inhibition. Complex sleep-related behaviours with no memory of the incident such as "sleep-driving", preparing and eating food, making phone calls, having sex while not fully awake have been reported. Caution in patients with history of drug or alcohol dependence and/or abuse. Worsening of depression, emergence of suicidality have been reported. Eszopiclone has rapid onset of action and must be taken immediately before bedtime or after experiencing difficulty sleeping. May impair ability to drive or operate machinery. Hypersensitivity reaction including angioedema involving the tongue, glottis or larynx, and symptoms suggestive of anaphylaxis have been reported. Abrupt discontinuance or rapid dose reduction may cause withdrawal symptoms. Caution in hepatic impairment; elderly/debilitated patients. Safety and efficacy have not been established in children <18 yr. Pregnancy and lactation. Lactation: excretion in milk unknown; use with caution

Pregnancy Available pharmacovigilance data with use in pregnant women are insufficient to identify drug-associated risk of major birth defects, miscarriage, or adverse maternal or fetal outcomes Animal data In animal reproduction studies conducted in pregnant rats and rabbits throughout organogenesis, there was no evidence of teratogenicity; administration to rats throughout pregnancy and lactation resulted in offspring toxicities at all doses tested; lowest dose was approximately 200 times maximum recommended human dose (MRHD) of 3 mg/day based on mg/ m² body surface area Lactation There are no data on prescence in either human or animal milk, effects on breastfed infant, or on milk production; developmental and health benefits of breastfeeding should be considered along with mother’s clinical need for therapy and any potential adverse effects on breastfed infant from therapy or underlying maternal condition
Concurrent use of CYP3A4 inhibitors (e.g. ketoconazole, itraconazole, clarithromycin, nefazodone, troleandomycin, ritonavir, nelfinavir) may decrease metabolism and increase plasma concentrations of Eszopiclone; dosage reduction of Eszopiclone may be needed. Concurrent use with CYP3A4 inducers (e.g. rifampicin) may reduce concentrations of Eszopiclone. May enhance adverse CNS effects when used with alcohol, anticonvulsants, antihistamines, or other psychotropic drugs. Concurrent use with flumazenil may diminish the sedative effect of nonbenzodiazepine hypnotics.
