Qualitative and quantitative composition Zopiclone 7.5 mg film-coated tablets: Each film-coated tablet contains 7.5 mg zopiclone. Excipient with known effect: Each film-coated tablet contains 80.00 mg lactose monohydrate. Each 7.5 mg film-coated tablet contains 0.13 mg sodium. For the full list of excipients, see section 6.1.3. Pharmaceutical form Film-coated tablet Zopiclone 7.5 mg film-coated tablets: White, round, (diameter: 7.6mm), biconvex film coated tablets debossed with ‘Z & 2’ separated with break line on one side and break line on the other side. The tablet can be divided into equal doses.4. Clinical particulars 4.1 Therapeutic indications Short-term treatment of insomnia in adults, including difficulties in falling asleep, nocturnal awakening and early awakening, transient, situational or chronic insomnia, and insomnia secondary to psychiatric disturbances, in situations where the insomnia is debilitating or is causing severe distress for the patient. Long term continuous use is not recommended. A course of treatment should employ the lowest effective dose.4.2 Posology and method of administration Use the lowest effective dose. Zopiclone should be taken in a single intake and not be re-administered during the same night. Treatment should be as short as possible. Posology Adults The recommended dose for adults is 7.5 mg (two tablets of 3.75 mg or one tablet of 7.5 mg) by the oral route shortly before retiring. Elderly A lower dose of 3.75mg zopiclone should be employed to start treatment in the elderly. Depending on effectiveness and acceptability, the dosage subsequently may be increased if clinically necessary. Patients with hepatic insufficiency: As elimination of zopiclone may be reduced in patients with hepatic dysfunction, a lower dose of 3.75mg zopiclone nightly is recommended. The standard dose of 7.5mg zopiclone may be used with caution in some cases, depending on effectiveness and acceptability. Renal insufficiency: Although no accumulation of zopiclone or its metabolites have been found in patients with renal insufficiency, it is advisable to begin treatment of patients with reduced renal function at 3.75 mg. Chronic respiratory insufficiency In patients with chronic respiratory insufficiency, a starting dose of 3.75 mg zopiclone is recommended initially. The dosage subsequently may be increased to 7.5 mg. Paediatric population: Zopiclone should not be used children and adolescents less than 18 years. The safety and efficacy of zopiclone in children and adolescents aged less than 18 years have not been established. Treatment duration Transient insomnia 2 – 5 days. Short term insomnia 2 – 3 weeks. A single course of treatment should not continue for longer than 4 weeks including any tapering off., Extension beyond the maximum treatment period should not take place without reevaluation of the patient’s status since the risk of abuse and dependence increases with the duration of treatment (see section 4.4). The product should be taken just before retiring for the night. Method of administration For oral use. Each tablet should be swallowed without sucking, chewing or breaking.4.3 Contraindications Hypersensitivity to the active substance or to any of the excipients listed in section 6.1. • Myasthenia gravis • Respiratory failure • Severe sleep apnoea syndrome • Children and adolescents under 18 years of age • Severe hepatic insufficiency • Who have previously experienced complex sleep behaviours after taking zopiclone, see section 4.4 4.4 Special warnings and precautions for use The cause of insomnia should be identified wherever possible and the underlying factors treated before a hypnotic is prescribed. The lack of relief from insomnia after 7-10 days of treatment indicates possibly the presence of a primary psychiatric and / or medical pathology or the presence of an erroneous perception of the state of sleep Specific patient groups Use in hepatic insufficiency: A reduced dosage is recommended, see Posology. Benzodiazepines are not indicated to treat patients with severe hepatic insufficiency as they may precipitate encephalopathy (see section 4.3 contraindications). Use in renal insufficiency : A reduced dosage is recommended, see Posology. Use in respiratory insufficiency: As hypnotics have the capacity to depress respiratory drive, precautions should be observed if zopiclone is prescribed to patients with compromised respiratory function (see section 4.8). A lower dose is recommended for patients with chronic respiratory insufficiency due to the risk of respiratory depression. Use in Paediatric population: Zopiclone should not be used children and adolescents less than 18 years. The safety and efficacy of zopiclone in children and adolescents aged less than 18 years have not been established. Use in Elderly patients Elderly should be given a reduced dose (see section 4.2). Due to the muscle relaxant effect of zopiclone, there is a risk of fall, especially in the elderly if they get up during the night. Risk of dependence: Clinical experience to date with Zopiclone suggests that the risk of dependence is minimal when the duration of treatment is limited to not more than 4 weeks. The use of benzodiazepines and benzodiazepine-like substances (even at therapeutic doses) can lead to the development of physical and psychological dependence or abuse upon these products. The risk of dependence or abuse increases the higher the dose and the longer the period of treatment; the risk of dependence or abuse is also greater in patient with a history of alcohol or other pshychotropics or drug abuse or those who have marked personality disorders. The decision to use a hypnotic in such patients should be taken only with this clearly in mind. If physical dependence occurs, sudden discontinuation of the treatment will be accompanied by withdrawal symptoms (see warnings and precautions). These may be expressed as headaches, muscle pain, extreme anxiety, tension, restlessness, confusion and irritability. In severe cases the following symptoms may occur: derealisation, depersonalisation, hyperacusis, numbness and tingling of the extremities, hypersensitivity to light, noise or physical contact, hallucinations or epileptic seizures. Rare cases of abuse have been reported. Withdrawal The termination of treatment with Zopiclone is unlikely to be associated with withdrawal effects when duration of treatment is limited to 4 weeks. Patients may benefit from tapering of the dose before discontinuation. (See also section 4.8. Undesirable Effects). Depression: As with other hypnotics, zopiclone does not constitute a treatment for depression and may even unmask its symptoms (suicide may be precipitated in such patients). Any underlying cause of insomnia should be addressed carefully before symptomatic treatment to avoid under treating potentially serious effects of depression. Suicidal tendencies maybe present, therefore the least amount of zopiclone that is feasible should be supplied to these patients to avoid the possibility of intentional overdose by the patient. Since insomnia may be a symptom of depression, the patient should be re-evaluated if insomnia persists. Suicidality: Some epidemiological studies indicate an increased incidence of suicide and suicide attempts in patients with or without depression, and treated with benzodiazepines or hypnotics, including zopiclone. However, a causal association has not been demonstrated. Rebound insomnia A transient syndrome where the symptoms which led to treatment with a benzodiazepine or benzodiazepine-like agent recur in an enhanced form on discontinuation of therapy. It may be accompanied by other reactions including mood changes, anxiety and restlessness. Since the risk of withdrawal/rebound phenomena is increased after prolonged treatment, or abrupt discontinuation of therapy, it is, therefore, recommended to decrease the dosage gradually and to advise the patient accordingly. A course of treatment should employ the lowest effective dose for the minimum length of time necessary for effective treatment. See posology for guidance on possible treatment regimen. A course of treatment should not continue for longer than 4 weeks including any tapering off (see section 4.8). Tolerance Some loss of efficacy to the hypnotic effect of benzodiazepines and benzodiazepine-like agents may develop after repeated use for a few weeks. However, with zopiclone there is an absence of any marked tolerance during treatment periods of up to 4 weeks. Amnesia Anterograde amnesia may occur, especially when sleep is interrupted or when retiring to bed is delayed after taking the tablet. Therefore to reduce the possibility of anterograde amnesia, patients should ensure that they take the tablet when certain of retiring for the night and they are able to have a full night’s sleep (uninterrupted sleep of about 8 hours). Psychomotor impairment Like other sedative/hypnotic drugs, zopiclone has CNS-depressant effects. The risk of psychomotor impairment, including impaired driving ability, is increased if: zopiclone is taken within 12 hours of performing activities that require mental alertness, a dose higher than the recommended dose is taken, or zopiclone is co-administered with other CNSdepressants, alcohol or with other drugs that increase the blood levels of zopiclone (see section 4.5). Patients should be cautioned against engaging in hazardous occupations requiring complete mental alertness or motor coordination such as operating machinery or driving a motor vehicle following administration of zopiclone and in particular during the 12 hours following that administration. Other Psychiatric and paradoxical reactions Other psychiatric and paradoxical reactions have been reported (see section 4.8 Undesirable effects), like restlessness, agitation, irritability, aggression, delusion, anger, nightmares, hallucinations, inappropriate behaviour and other adverse behavioural effects are known to occur when using sedative/hypnotic agents like zopiclone. Should this occur, use of zopiclone should be discontinued. These reactions are more likely to occur in the elderly. Somnambulism and associated behaviours Complex sleep behavior, including sleep walking and other associated behaviours such as “sleep driving”, preparing and eating food, or making phone calls, with amnesia for the event, have been reported in patients who have taken zopiclone and were not fully awake. These events may occur following the first or any subsequent use of zopiclone. The use of alcohol and other CNS-depressants with zopiclone appears to increase the risk of such behaviours, as does the use of zopiclone at doses exceeding the maximum recommended dose. Discontinuation of zopiclone should be strongly considered for patients who report such behaviours (see section 4.3). Risk from concomitant use of opioids: Concomitant use of zopiclone and opioids may result in sedation, respiratory depression, coma and death. Because of these risks, concomitant prescribing of sedative medicines such as benzodiazepines or related drugs such as Zopiclone with opioids should be reserved for patients for whom alternative treatment options are not possible. If a decision is made to prescribe zopiclone concomitantly with opioids, the lowest effective dose should be used, and the duration of treatment should be as short as possible (see also general dose recommendation in section 4.2). The patients should be followed closely for signs and symptoms of respiratory depression and sedation. In this respect, it is strongly recommended to inform patients and their caregivers (where applicable) to be aware of these symptoms (see section 4.5). Excipients This medicinal product contains lactose. Patients with rare hereditary problems of galactose intolerance,total lactase deficiency or glucose-galactose malabsorption should not take this medicine. Zopiclone contains Sodium This medicine contains less than 1 mmol sodium (23 mg) per tablet, that is to say essentially ‘sodium free’.4.5 Interaction with other medicinal products and other forms of interaction Association not recommended: Concomitant use with alcohol is not recommended because the sedative effect of zopiclone may be intensified when used in combination with alcohol. In particular, this may affect the ability to drive or operate machines. Associations to be taken in to account: In combination with CNS depressants an enhancement of the central depressive effect may occur. The therapeutic benefit of co-administration with antipsychotics (neuroleptics), hypnotics, anxiolytics/sedatives, antidepressant agents, narcotic analgesics, anti-epileptic drugs, anaesthetics and sedative antihistamines should therefore be carefully weighed. In the case of narcotic analgesics, enhancement of euphoria may also occur leading to an increase in psychic dependence. Compounds which inhibit certain hepatic enzymes (particularly cytochrome P450) may enhance the activity of benzodiazepines and benzodiazepine-like agents. Compounds which inhibit certain hepatic enzymes (particularly cytochrome P450) may enhance the activity of benzodiazepines and benzodiazepine-like agents. Since zopiclone is metabolised by P450 (CYP)3A4 isoenzyme (see section 5.2 Pharmacokinetic Properties), the plasma levels of zopiclone and thus the effect of zopiclone may be increased when used in combination with drugs which inhibit CYP3A4, such as such as erythromycin, clarithromycin, azole antimycotics such as ketoconazole, itraconazole and ritonavir. Dose reduction should be considered if zopiclone is co-administered with CYP3A4 inhibitors. Co-administration with Drugs which induce CYP3A4, like phenobarbital, phenytoin, carbamazepine, rifampicin and products containing St John’s wort, may reduce zopiclone plasma levels and thus the effect of zopiclone. A dose increase for zopiclone may be required when it is co-administered with CYP3A4 inducers. The effect of erythromycin on the pharmacokinetics of zopiclone has been studies in 10 healthy subjects. The AUC of zopiclone is increased by 80% in presence of erythromycin which indicates that erythromycin can inhibit the metabolism of drugs metabolised by CYP 3A4. As a consequence, the hypnotic effect of zopiclone may be enhanced. Opioids: The concomitant use of sedative medicines such as benzodiazepines or related drugs such as Zopiclone with opioids increases the risk of sedation, respiratory depression, coma and death because of additive CNS depressant effect. The dosage and duration of concomitant use should be limited (see section 4.4).4.6 Fertility, pregnancy and lactation Pregnancy Zopiclone should not be used during pregnancy. Animal studies do not indicate direct or indirect harmful effects with respect to reproductive toxicity. Zopiclone crosses the placenta. A large amount of data on pregnant women (more than 1000 pregnancy outcomes) collected from cohort studies has not demonstrated evidence of the occurrence of malformations following exposure to benzodiazepines or benzodiazepine like substances during the first trimester of pregnancy. However, certain case-control studies reported an increased incidence of cleft lip and palate associated with use of benzodiazepines during pregnancy. Cases of reduced fetal movement and fetal heart rate variability have been described after administration of benzodiazepines or benzodiazepine-like substances during the second and/or third trimester of pregnancy Moreover, if zopiclone is prescribed during the last three months of pregnancy or during labour, due to the pharmacological action of the product, effects on the neonate, such as hypothermia, hypotonia, feeding difficulties ( floppy infant syndrome ) and respiratory depression can be expected due to the pharmacological action of the product. Cases of severe neonatal respiratory depression have been reported. Infants born to mothers who took benzodiazepines or benzodiazepine-like agents chronically during the latter stages of pregnancy may have developed physical dependence and may be at some risk of developing withdrawal symptoms in the postnatal period. Appropriate monitoring of the newborn in the postnatal period is recommended. If the product is prescribed to a woman of child bearing potential, she should be advised to contact her physician about stopping the product if she intends to become pregnant, or suspects that she is pregnant, Breast feeding Zopiclone is excreted in breast milk, although the concentration of zopiclone in the breast milk is low, use in nursing mothers must be avoided. Fertility In a double-blind long-term study on healthy male volunteers, no negative changes in sperm volume, sperm concentration, sperm motility and cell morphology were found in spermatograms at doses of 7.5 mg zopiclone over a period of 84 days.4.7 Effects on ability to drive and use machines Because of its pharmacological properties and its effect on central nervous system, Zopiclone may adversely affect the ability to drive or to use machines. The risk of psychomotor impairment, including impaired driving ability, is increased if: • zopiclone is taken within 12 hours of performing activities that require mental alertness, • a dose higher than the recommended dose is taken, or • zopiclone is co-administered with other CNS depressants, alcohol, or with other drugs that increase the blood levels of zopiclone. Patients should be cautioned against engaging in hazardous occupations requiring complete mental alertness or motor coordination such as operating machinery or driving a motor vehicle following administration of zopiclone and in particular during the 12 hours following that administration.4.8 Undesirable effects The following CIOMS frequency rating is used, when applicable: Frequency estimate: very common (≥ 1/10); common (≥ 1/100 to < 1/10); uncommon (≥ 1/1,000 to < 1/100); rare (≥ 1/10,000 to <1/1,000); and very rare (<1/10,000); not known (cannot be estimated from the available data).

Withdrawal syndrome has been reported upon discontinuation of zopiclone. (See section 4.4. Special Warnings and Precautions for Use). Withdrawal symptoms vary and may include rebound insomnia, muscle pain,anxiety, tremor, sweating, agitation, confusion, headache, palpitations, tachycardia, delirium, nightmares, hallucinations, panic attacks, muscle aches/cramps, gastrointestinal disturbances and irritability.
- In severe cases the following symptoms may occur: derealisation, depersonalisation, hyperacusis, numbness and tingling of the extremities, hypersensitivity to light, noise and physical contact, hallucinations.
- In very rare cases, seizures may occur.
- Reporting of suspected adverse reactions Reporting suspected adverse reactions after authorisation of the medicinal product is important.
It allows continued monitoring of the benefit/risk balance of the medicinal product. Healthcare professionals are asked to report any suspected adverse reactions via the Yellow Card Scheme at www.mhra.gov.uk/yellowcard or search for MHRA Yellow Card in the Google Play or Apple App Store.4.9 Overdose Fatal dose not known.
Symptoms In the cases of overdosage reported,Overdose is usually manifested by varying degrees of central nervous system depression ranging from drowsiness to coma according to the quantity ingested. In mild cases, symptoms include drowsiness, confusion and lethargy; in more severe cases, symptoms may include ataxia, hypotonia, hypotension, methaemoglobinaemia, respiratory depression, and coma.
Overdose should not be life threatening unless combined with other CNS depressants, including alcohol. Other risk factors, such as the presence of concomitant illness and the debilitated state of the patient, may contribute to the severity of symptoms and very rarely can result in fatal outcome.
- Management Symptomatic and supportive treatment in adequate clinical environment is recommended, attention should be paid to respiratory and cardiovascular functions.
- Consider activated charcoal if an adult has ingested more than 150 mg or a child more than 1.5 mg/kg within one hour.
- Alternatively, consider gastric lavage in adults within one hour of a potentially life threatening overdose.
Hemodialysis is not effective because it is high zopiclone distribution volume If CNS depression is severe consider the use of flumazenil. It has a short half-life (about an hour). NOT TO BE USED IN MIXED OVERDOSE OR AS A “DIAGNOSTIC” TEST. Management should include general symptomatic and supportive measures including a clear airway and monitoring cardiac and vital signs until stable.5.
Pharmacological properties 5.1 Pharmacodynamic properties Pharmacotherapeutic group: hypnotic-sedative. ATC code N05C F01 Mechanism of action: Zopiclone is a benzodiazepine-like hypnotic agent which belongs to the group of cyclopyrrolones. It rapidly initiates and sustains sleep without reduction of total REM sleep and with preservation of slow wave sleep.
Negligible residual effects are seen the following morning. The pharmacological properties are: hypnotic, sedation, anxiolysis, anticonvulsion, muscle relaxation. These effects are related to a specific agonistic effect on central receptors belonging to the GABAA, macromolecular complex which regulates the opening of chloride channels.
However, it has been shown that zopiclone and other cyclopyrrolones act on a different site to those of benzodiazepines including different conformational changes in the receptor complex. Pharmacodynamic effects Zopiclone has been found to increase the duration of sleep and improve the quality of sleep, reduce the nightly and early morning awakenings in humans.
This activity is supplemented by characteristic results of electroencephalography. Sleep registration has proven that zopiclone decreases the phase-one sleep and increases the phase-two sleep, while maintaining and lengthening the deep sleep phases (III and IV) and does not affect the paradoxical (REM) sleep in patients suffering from insomnia.5.2 Pharmacokinetic properties Absorption Zopiclone is swiftly absorbed.
- Maximum plasma concentrations are achieved after 1½ – 2 hours and are approximately 30 and 60 ng/ml after administration of 3.75 mg and 7.5 mg respectively.
- Absorption is the same in men and women and is not affected by simultaneous ingestion of food or repetition of doses.
- Distribution Zopiclone is swiftly distributed from the vascular compartment.
The plasma protein binding is at least 45% and is not saturable. There is very little risk of drug interactions due to protein binding. The volume of distribution is 91.8 – 104.6 litres. The decrease in plasma level does not depend on the dose between 3.75 and 15 mg.
No accumulation occurs after repeated administration and individual differences appear slight. During lactation, zopiclone kinetics in plasma and milk are similar, the milk/plasma ratio of zopiclone was about 0.5 and remained constant over time and the maximum zopiclone concentration in milk was found between 1 and 6 hours following maternal administration.
It is estimated that the infant can consume no more than 1.0% of the maternal dose in 24 hours with human milk. Biotransformation The most important metabolites are the N-oxide derivative (pharmacologically active in animals) and the N-desmethyl metabolite (pharmacologically inactive in animals).
- An in-vitro study indicates that cytochrome P450 (CYP) 3A4 is the major isoenzyme involved in the metabolism of zopiclone to both metabolites, and that CYP2C8 is also involved with N-desmethyl zopiclone formation.
- Their apparent half-life times are approximately 4.5 hours and 1.5 hours respectively.
- No significant accumulation of the compound is seen following repeat dosing, (15mg) for 14 days.
In animals, no enzyme induction has been observed even at high doses. Elimination The low renal clearance of zopiclone (on average 8.4 ml/min) compared to the plasma clearance (232 ml/min) shows that zopiclone is cleared chiefly by metabolism. Zopiclone is eliminated in the urine (approximately 80%) in the form of unconjugated metabolites (N-oxide and N-desmethyl derivatives) and in the faeces (approximately 16%).The elimination half-life of unchanged zopiclone at recommended doses is approximately 5 hours.
Special patient groups In various trials with elderly patients, no accumulation of zopiclone was observed in the plasma after repeated doses, in spite of a slight reduction in the renal function and extension of the elimination half-life to approximately 7 hours. In renal insufficiency, no accumulation of zopiclone or its metabolites have been detected after prolonged administration.
Zopiclone crosses the dialysing membrane. However, in the event of an overdose, hemodialysis is not effective in the event of an overdose due to the large volume of distribution of zopiclone and the low molecular weight (see section 4.9). In patients with cirrhosis of the liver the plasma clearance of zopiclone is reduced by approximately 40% due to a decrease of the demethylation process and an extended half-life of about 8 hours is observed.
For this reason the initial dosage should be reduced for these patients.5.3 Preclinical safety data Chronic toxicity Hepatotoxic effects were elicited in repeated dose toxicity studies conducted in rats and dogs. In dogs anaemia were evident in some studies. Mutagenicity and carcinogenicity Zopiclone did not show a mutagenic potential in vitro and in vivo.
An increased incidence of mammary carcinomas in female rats at high multiples of the maximum plasma concentration of therapeutic doses in humans have been attributed to elevated serum levels of 17-beta-estradiol. An increased incidence of thyroid tumors in rats has been attributed to elevated TSH serum levels.
- In humans, zopiclone has no effects on thyroid hormones.
- Reproduction toxicity Fertility was reduced in two rat studies, while zopiclone did not adversely affect fertility in rabbits.Foetal developmental retardations and foetotoxic effects in rats and rabbits were observed only at doses well above the maximum human dosage.
There was no evidence of a teratogenic potential.6.

Can you take 2 zopiclone 7.5 mg?
If you forget to take it – If you forget to take it by bedtime, just skip the missed dose and take your next dose at the usual time the next night. Never take 2 doses at the same time. Never take an extra dose to make up for a forgotten one.
Can I take 15mg of zopiclone?
Abstract – Sixty insomniac patients participated in a controlled double-blind parallel group study designed to investigate the dose-response relationship of zopiclone. Following 1 day of treatment with placebo, patients were randomly assigned to 1 of 6 groups and received treatment for 7 days with either placebo, or flurazepam 30 mg, or zopiclone, 3.75 mg, 7.5 mg, 11.25 mg or 15 mg.
Four patients were dropped from the study; two from the placebo group due to ineffectiveness and one each in zopiclone 11.25 mg and 15 mg groups due to side-effects. Flurazepam 30 mg significantly improved sleep induction and maintenance by comparison to placebo and was indistinguishable from zopiclone 7.5 mg or higher.
Results of a self-administered sleep questionnaire found a predominantly linear relationship between the dose of zopiclone administered and the degree of sleep improvement. The greatest increment in improvement was generally obtained with 3.5 mg and 7.5 mg of zopiclone, with some additional benefit occurring with zopiclone 11.25 mg.
What happens if you take 2 7.5 zopiclone?

Clinical particulars 4.1 Therapeutic indications Short-term treatment of insomnia in adults, including difficulties in falling asleep, nocturnal awakening and early awakening, transient, situational or chronic insomnia, and insomnia secondary to psychiatric disturbances, in situations where the insomnia is debilitating or is causing severe distress for the patient. Long term continuous use is not recommended. A course of treatment should employ the lowest effective dose.4.2 Posology and method of administration Use the lowest effective dose. Zopiclone should be taken in a single intake and not be re-administered during the same night. Treatment should be as short as possible. Posology Adults The recommended dose for adults is 7.5 mg (two tablets of 3.75 mg or one tablet of 7.5 mg) by the oral route shortly before retiring. Elderly A lower dose of 3.75mg zopiclone should be employed to start treatment in the elderly. Depending on effectiveness and acceptability, the dosage subsequently may be increased if clinically necessary. Patients with hepatic insufficiency: As elimination of zopiclone may be reduced in patients with hepatic dysfunction, a lower dose of 3.75mg zopiclone nightly is recommended. The standard dose of 7.5mg zopiclone may be used with caution in some cases, depending on effectiveness and acceptability.

A single course of treatment should not continue for longer than 4 weeks including any tapering off., Extension beyond the maximum treatment period should not take place without reevaluation of the patient’s status since the risk of abuse and dependence increases with the duration of treatment (see section 4.4). The product should be taken just before retiring for the night. Method of administration For oral use. Each tablet should be swallowed without sucking, chewing or breaking.4.3 Contraindications Hypersensitivity to the active substance or to any of the excipients listed in section 6.1. • Myasthenia gravis • Respiratory failure • Severe sleep apnoea syndrome • Children and adolescents under 18 years of age • Severe hepatic insufficiency • Who have previously experienced complex sleep behaviours after taking zopiclone, see section 4.4 4.4 Special warnings and precautions for use The cause of insomnia should be identified wherever possible and the underlying factors treated before a hypnotic is prescribed. The lack of relief from insomnia after 7-10 days of treatment indicates possibly the presence of a primary psychiatric and / or medical pathology or the presence of an erroneous perception of the state of sleep Specific patient groups Use in hepatic insufficiency: A reduced dosage is recommended, see Posology. Benzodiazepines are not indicated to treat patients with severe hepatic insufficiency as they may precipitate encephalopathy (see section 4.3 contraindications). Use in renal insufficiency : A reduced dosage is recommended, see Posology. Use in respiratory insufficiency: As hypnotics have the capacity to depress respiratory drive, precautions should be observed if zopiclone is prescribed to patients with compromised respiratory function (see section 4.8). A lower dose is recommended for patients with chronic respiratory insufficiency due to the risk of respiratory depression. Use in Paediatric population: Zopiclone should not be used children and adolescents less than 18 years. The safety and efficacy of zopiclone in children and adolescents aged less than 18 years have not been established. Use in Elderly patients Elderly should be given a reduced dose (see section 4.2). Due to the muscle relaxant effect of zopiclone, there is a risk of fall, especially in the elderly if they get up during the night. Risk of dependence: Clinical experience to date with Zopiclone suggests that the risk of dependence is minimal when the duration of treatment is limited to not more than 4 weeks. The use of benzodiazepines and benzodiazepine-like substances (even at therapeutic doses) can lead to the development of physical and psychological dependence or abuse upon these products. The risk of dependence or abuse increases the higher the dose and the longer the period of treatment; the risk of dependence or abuse is also greater in patient with a history of alcohol or other pshychotropics or drug abuse or those who have marked personality disorders. The decision to use a hypnotic in such patients should be taken only with this clearly in mind. If physical dependence occurs, sudden discontinuation of the treatment will be accompanied by withdrawal symptoms (see warnings and precautions). These may be expressed as headaches, muscle pain, extreme anxiety, tension, restlessness, confusion and irritability. In severe cases the following symptoms may occur: derealisation, depersonalisation, hyperacusis, numbness and tingling of the extremities, hypersensitivity to light, noise or physical contact, hallucinations or epileptic seizures. Rare cases of abuse have been reported. Withdrawal The termination of treatment with Zopiclone is unlikely to be associated with withdrawal effects when duration of treatment is limited to 4 weeks. Patients may benefit from tapering of the dose before discontinuation. (See also section 4.8. Undesirable Effects). Depression: As with other hypnotics, zopiclone does not constitute a treatment for depression and may even unmask its symptoms (suicide may be precipitated in such patients). Any underlying cause of insomnia should be addressed carefully before symptomatic treatment to avoid under treating potentially serious effects of depression. Suicidal tendencies maybe present, therefore the least amount of zopiclone that is feasible should be supplied to these patients to avoid the possibility of intentional overdose by the patient. Since insomnia may be a symptom of depression, the patient should be re-evaluated if insomnia persists. Suicidality: Some epidemiological studies indicate an increased incidence of suicide and suicide attempts in patients with or without depression, and treated with benzodiazepines or hypnotics, including zopiclone. However, a causal association has not been demonstrated. Rebound insomnia A transient syndrome where the symptoms which led to treatment with a benzodiazepine or benzodiazepine-like agent recur in an enhanced form on discontinuation of therapy. It may be accompanied by other reactions including mood changes, anxiety and restlessness. Since the risk of withdrawal/rebound phenomena is increased after prolonged treatment, or abrupt discontinuation of therapy, it is, therefore, recommended to decrease the dosage gradually and to advise the patient accordingly. A course of treatment should employ the lowest effective dose for the minimum length of time necessary for effective treatment. See posology for guidance on possible treatment regimen. A course of treatment should not continue for longer than 4 weeks including any tapering off (see section 4.8). Tolerance Some loss of efficacy to the hypnotic effect of benzodiazepines and benzodiazepine-like agents may develop after repeated use for a few weeks. However, with zopiclone there is an absence of any marked tolerance during treatment periods of up to 4 weeks. Amnesia Anterograde amnesia may occur, especially when sleep is interrupted or when retiring to bed is delayed after taking the tablet. Therefore to reduce the possibility of anterograde amnesia, patients should ensure that they take the tablet when certain of retiring for the night and they are able to have a full night’s sleep (uninterrupted sleep of about 8 hours). Psychomotor impairment Like other sedative/hypnotic drugs, zopiclone has CNS-depressant effects. The risk of psychomotor impairment, including impaired driving ability, is increased if: zopiclone is taken within 12 hours of performing activities that require mental alertness, a dose higher than the recommended dose is taken, or zopiclone is co-administered with other CNSdepressants, alcohol or with other drugs that increase the blood levels of zopiclone (see section 4.5). Patients should be cautioned against engaging in hazardous occupations requiring complete mental alertness or motor coordination such as operating machinery or driving a motor vehicle following administration of zopiclone and in particular during the 12 hours following that administration. Other Psychiatric and paradoxical reactions Other psychiatric and paradoxical reactions have been reported (see section 4.8 Undesirable effects), like restlessness, agitation, irritability, aggression, delusion, anger, nightmares, hallucinations, inappropriate behaviour and other adverse behavioural effects are known to occur when using sedative/hypnotic agents like zopiclone. Should this occur, use of zopiclone should be discontinued. These reactions are more likely to occur in the elderly. Somnambulism and associated behaviours Complex sleep behavior, including sleep walking and other associated behaviours such as “sleep driving”, preparing and eating food, or making phone calls, with amnesia for the event, have been reported in patients who have taken zopiclone and were not fully awake. These events may occur following the first or any subsequent use of zopiclone. The use of alcohol and other CNS-depressants with zopiclone appears to increase the risk of such behaviours, as does the use of zopiclone at doses exceeding the maximum recommended dose. Discontinuation of zopiclone should be strongly considered for patients who report such behaviours (see section 4.3). Risk from concomitant use of opioids: Concomitant use of zopiclone and opioids may result in sedation, respiratory depression, coma and death. Because of these risks, concomitant prescribing of sedative medicines such as benzodiazepines or related drugs such as Zopiclone with opioids should be reserved for patients for whom alternative treatment options are not possible. If a decision is made to prescribe zopiclone concomitantly with opioids, the lowest effective dose should be used, and the duration of treatment should be as short as possible (see also general dose recommendation in section 4.2). The patients should be followed closely for signs and symptoms of respiratory depression and sedation. In this respect, it is strongly recommended to inform patients and their caregivers (where applicable) to be aware of these symptoms (see section 4.5). Excipients This medicinal product contains lactose. Patients with rare hereditary problems of galactose intolerance,total lactase deficiency or glucose-galactose malabsorption should not take this medicine. Zopiclone contains Sodium This medicine contains less than 1 mmol sodium (23 mg) per tablet, that is to say essentially ‘sodium free’.4.5 Interaction with other medicinal products and other forms of interaction Association not recommended: Concomitant use with alcohol is not recommended because the sedative effect of zopiclone may be intensified when used in combination with alcohol. In particular, this may affect the ability to drive or operate machines. Associations to be taken in to account: In combination with CNS depressants an enhancement of the central depressive effect may occur. The therapeutic benefit of co-administration with antipsychotics (neuroleptics), hypnotics, anxiolytics/sedatives, antidepressant agents, narcotic analgesics, anti-epileptic drugs, anaesthetics and sedative antihistamines should therefore be carefully weighed. In the case of narcotic analgesics, enhancement of euphoria may also occur leading to an increase in psychic dependence. Compounds which inhibit certain hepatic enzymes (particularly cytochrome P450) may enhance the activity of benzodiazepines and benzodiazepine-like agents. Compounds which inhibit certain hepatic enzymes (particularly cytochrome P450) may enhance the activity of benzodiazepines and benzodiazepine-like agents. Since zopiclone is metabolised by P450 (CYP)3A4 isoenzyme (see section 5.2 Pharmacokinetic Properties), the plasma levels of zopiclone and thus the effect of zopiclone may be increased when used in combination with drugs which inhibit CYP3A4, such as such as erythromycin, clarithromycin, azole antimycotics such as ketoconazole, itraconazole and ritonavir. Dose reduction should be considered if zopiclone is co-administered with CYP3A4 inhibitors. Co-administration with Drugs which induce CYP3A4, like phenobarbital, phenytoin, carbamazepine, rifampicin and products containing St John’s wort, may reduce zopiclone plasma levels and thus the effect of zopiclone. A dose increase for zopiclone may be required when it is co-administered with CYP3A4 inducers. The effect of erythromycin on the pharmacokinetics of zopiclone has been studies in 10 healthy subjects. The AUC of zopiclone is increased by 80% in presence of erythromycin which indicates that erythromycin can inhibit the metabolism of drugs metabolised by CYP 3A4. As a consequence, the hypnotic effect of zopiclone may be enhanced. Opioids: The concomitant use of sedative medicines such as benzodiazepines or related drugs such as Zopiclone with opioids increases the risk of sedation, respiratory depression, coma and death because of additive CNS depressant effect. The dosage and duration of concomitant use should be limited (see section 4.4).4.6 Fertility, pregnancy and lactation Pregnancy Zopiclone should not be used during pregnancy. Animal studies do not indicate direct or indirect harmful effects with respect to reproductive toxicity. Zopiclone crosses the placenta. A large amount of data on pregnant women (more than 1000 pregnancy outcomes) collected from cohort studies has not demonstrated evidence of the occurrence of malformations following exposure to benzodiazepines or benzodiazepine like substances during the first trimester of pregnancy. However, certain case-control studies reported an increased incidence of cleft lip and palate associated with use of benzodiazepines during pregnancy. Cases of reduced fetal movement and fetal heart rate variability have been described after administration of benzodiazepines or benzodiazepine-like substances during the second and/or third trimester of pregnancy Moreover, if zopiclone is prescribed during the last three months of pregnancy or during labour, due to the pharmacological action of the product, effects on the neonate, such as hypothermia, hypotonia, feeding difficulties ( floppy infant syndrome ) and respiratory depression can be expected due to the pharmacological action of the product. Cases of severe neonatal respiratory depression have been reported. Infants born to mothers who took benzodiazepines or benzodiazepine-like agents chronically during the latter stages of pregnancy may have developed physical dependence and may be at some risk of developing withdrawal symptoms in the postnatal period. Appropriate monitoring of the newborn in the postnatal period is recommended. If the product is prescribed to a woman of child bearing potential, she should be advised to contact her physician about stopping the product if she intends to become pregnant, or suspects that she is pregnant, Breast feeding Zopiclone is excreted in breast milk, although the concentration of zopiclone in the breast milk is low, use in nursing mothers must be avoided. Fertility In a double-blind long-term study on healthy male volunteers, no negative changes in sperm volume, sperm concentration, sperm motility and cell morphology were found in spermatograms at doses of 7.5 mg zopiclone over a period of 84 days.4.7 Effects on ability to drive and use machines Because of its pharmacological properties and its effect on central nervous system, Zopiclone may adversely affect the ability to drive or to use machines. The risk of psychomotor impairment, including impaired driving ability, is increased if: • zopiclone is taken within 12 hours of performing activities that require mental alertness, • a dose higher than the recommended dose is taken, or • zopiclone is co-administered with other CNS depressants, alcohol, or with other drugs that increase the blood levels of zopiclone. Patients should be cautioned against engaging in hazardous occupations requiring complete mental alertness or motor coordination such as operating machinery or driving a motor vehicle following administration of zopiclone and in particular during the 12 hours following that administration.4.8 Undesirable effects The following CIOMS frequency rating is used, when applicable: Frequency estimate: very common (≥ 1/10); common (≥ 1/100 to < 1/10); uncommon (≥ 1/1,000 to < 1/100); rare (≥ 1/10,000 to <1/1,000); and very rare (<1/10,000); not known (cannot be estimated from the available data).

Withdrawal syndrome has been reported upon discontinuation of zopiclone. (See section 4.4. Special Warnings and Precautions for Use). Withdrawal symptoms vary and may include rebound insomnia, muscle pain,anxiety, tremor, sweating, agitation, confusion, headache, palpitations, tachycardia, delirium, nightmares, hallucinations, panic attacks, muscle aches/cramps, gastrointestinal disturbances and irritability.
- In severe cases the following symptoms may occur: derealisation, depersonalisation, hyperacusis, numbness and tingling of the extremities, hypersensitivity to light, noise and physical contact, hallucinations.
- In very rare cases, seizures may occur.
- Reporting of suspected adverse reactions Reporting suspected adverse reactions after authorisation of the medicinal product is important.
It allows continued monitoring of the benefit/risk balance of the medicinal product. Healthcare professionals are asked to report any suspected adverse reactions via the Yellow Card Scheme at www.mhra.gov.uk/yellowcard or search for MHRA Yellow Card in the Google Play or Apple App Store.4.9 Overdose Fatal dose not known.
Symptoms In the cases of overdosage reported,Overdose is usually manifested by varying degrees of central nervous system depression ranging from drowsiness to coma according to the quantity ingested. In mild cases, symptoms include drowsiness, confusion and lethargy; in more severe cases, symptoms may include ataxia, hypotonia, hypotension, methaemoglobinaemia, respiratory depression, and coma.
Overdose should not be life threatening unless combined with other CNS depressants, including alcohol. Other risk factors, such as the presence of concomitant illness and the debilitated state of the patient, may contribute to the severity of symptoms and very rarely can result in fatal outcome.
- Management Symptomatic and supportive treatment in adequate clinical environment is recommended, attention should be paid to respiratory and cardiovascular functions.
- Consider activated charcoal if an adult has ingested more than 150 mg or a child more than 1.5 mg/kg within one hour.
- Alternatively, consider gastric lavage in adults within one hour of a potentially life threatening overdose.
Hemodialysis is not effective because it is high zopiclone distribution volume If CNS depression is severe consider the use of flumazenil. It has a short half-life (about an hour). NOT TO BE USED IN MIXED OVERDOSE OR AS A “DIAGNOSTIC” TEST. Management should include general symptomatic and supportive measures including a clear airway and monitoring cardiac and vital signs until stable.5.
Pharmacological properties 5.1 Pharmacodynamic properties Pharmacotherapeutic group: hypnotic-sedative. ATC code N05C F01 Mechanism of action: Zopiclone is a benzodiazepine-like hypnotic agent which belongs to the group of cyclopyrrolones. It rapidly initiates and sustains sleep without reduction of total REM sleep and with preservation of slow wave sleep.
Negligible residual effects are seen the following morning. The pharmacological properties are: hypnotic, sedation, anxiolysis, anticonvulsion, muscle relaxation. These effects are related to a specific agonistic effect on central receptors belonging to the GABAA, macromolecular complex which regulates the opening of chloride channels.
However, it has been shown that zopiclone and other cyclopyrrolones act on a different site to those of benzodiazepines including different conformational changes in the receptor complex. Pharmacodynamic effects Zopiclone has been found to increase the duration of sleep and improve the quality of sleep, reduce the nightly and early morning awakenings in humans.
This activity is supplemented by characteristic results of electroencephalography. Sleep registration has proven that zopiclone decreases the phase-one sleep and increases the phase-two sleep, while maintaining and lengthening the deep sleep phases (III and IV) and does not affect the paradoxical (REM) sleep in patients suffering from insomnia.5.2 Pharmacokinetic properties Absorption Zopiclone is swiftly absorbed.
- Maximum plasma concentrations are achieved after 1½ – 2 hours and are approximately 30 and 60 ng/ml after administration of 3.75 mg and 7.5 mg respectively.
- Absorption is the same in men and women and is not affected by simultaneous ingestion of food or repetition of doses.
- Distribution Zopiclone is swiftly distributed from the vascular compartment.
The plasma protein binding is at least 45% and is not saturable. There is very little risk of drug interactions due to protein binding. The volume of distribution is 91.8 – 104.6 litres. The decrease in plasma level does not depend on the dose between 3.75 and 15 mg.
No accumulation occurs after repeated administration and individual differences appear slight. During lactation, zopiclone kinetics in plasma and milk are similar, the milk/plasma ratio of zopiclone was about 0.5 and remained constant over time and the maximum zopiclone concentration in milk was found between 1 and 6 hours following maternal administration.
It is estimated that the infant can consume no more than 1.0% of the maternal dose in 24 hours with human milk. Biotransformation The most important metabolites are the N-oxide derivative (pharmacologically active in animals) and the N-desmethyl metabolite (pharmacologically inactive in animals).
- An in-vitro study indicates that cytochrome P450 (CYP) 3A4 is the major isoenzyme involved in the metabolism of zopiclone to both metabolites, and that CYP2C8 is also involved with N-desmethyl zopiclone formation.
- Their apparent half-life times are approximately 4.5 hours and 1.5 hours respectively.
- No significant accumulation of the compound is seen following repeat dosing, (15mg) for 14 days.
In animals, no enzyme induction has been observed even at high doses. Elimination The low renal clearance of zopiclone (on average 8.4 ml/min) compared to the plasma clearance (232 ml/min) shows that zopiclone is cleared chiefly by metabolism. Zopiclone is eliminated in the urine (approximately 80%) in the form of unconjugated metabolites (N-oxide and N-desmethyl derivatives) and in the faeces (approximately 16%).The elimination half-life of unchanged zopiclone at recommended doses is approximately 5 hours.
- Special patient groups In various trials with elderly patients, no accumulation of zopiclone was observed in the plasma after repeated doses, in spite of a slight reduction in the renal function and extension of the elimination half-life to approximately 7 hours.
- In renal insufficiency, no accumulation of zopiclone or its metabolites have been detected after prolonged administration.
Zopiclone crosses the dialysing membrane. However, in the event of an overdose, hemodialysis is not effective in the event of an overdose due to the large volume of distribution of zopiclone and the low molecular weight (see section 4.9). In patients with cirrhosis of the liver the plasma clearance of zopiclone is reduced by approximately 40% due to a decrease of the demethylation process and an extended half-life of about 8 hours is observed.
For this reason the initial dosage should be reduced for these patients.5.3 Preclinical safety data Chronic toxicity Hepatotoxic effects were elicited in repeated dose toxicity studies conducted in rats and dogs. In dogs anaemia were evident in some studies. Mutagenicity and carcinogenicity Zopiclone did not show a mutagenic potential in vitro and in vivo.
An increased incidence of mammary carcinomas in female rats at high multiples of the maximum plasma concentration of therapeutic doses in humans have been attributed to elevated serum levels of 17-beta-estradiol. An increased incidence of thyroid tumors in rats has been attributed to elevated TSH serum levels.
In humans, zopiclone has no effects on thyroid hormones. Reproduction toxicity Fertility was reduced in two rat studies, while zopiclone did not adversely affect fertility in rabbits.Foetal developmental retardations and foetotoxic effects in rats and rabbits were observed only at doses well above the maximum human dosage.
There was no evidence of a teratogenic potential.6.

Is zopiclone a strong sleeping pill?
About zopiclone Zopiclone is a type of sleeping pill that can be taken for short-term treatment of severe insomnia. It helps you fall asleep more quickly, and also helps stop you waking up during the night. It works by affecting a calming chemical in your brain called gamma-aminobutyric acid (GABA).
Zopiclone takes around 1 hour to work.It’s usually prescribed for just 2 to 4 weeks. This is because your body gets used to it quickly and after this time it’s unlikely to have the same effect. Your body can also become dependent on it.Common side effects are a metallic taste in your mouth, a dry mouth, and daytime sleepiness.Do not drink alcohol while you’re on zopiclone. Having them together can make you go into a deep sleep where you find it difficult to wake up.If zopiclone makes you feel sleepy in the daytime, do not drive a car, ride a bike or use machinery.

What happens if you stay awake on zopiclone?
Mental effects Zopiclone helps you sleep, though users who manage to stay awake on it can feel drowsy and calm.
How long does 7.5 mg zopiclone last?
The side effects of taking zopiclone – The most frequently reported side effect of zopiclone, reported in about 10% of people, is a bitter or metallic taste.5 Other frequently reported side effects of zopiclone include:
nausea dizziness asthenia (abnormal physical weakness or lack of energy) increased sweating headaches sedation, somnolence and tiredness.
A study in healthy volunteers found no residual effects of the drug on psychomotor performance (i.e. activities such as throwing a ball, using a tool or driving a car) the day after a 7.5mg dose.3 However, there are other reports that do show impairment as a measure of coordination and performance of skilled tasks. Hypnotics are often prescribed to the elderly. There is however a concern that they may impair both balance and memory functions. More adverse effects on how the drugs such as zopiclone tend to have more adverse effects in older people. These include cognitive processes such as being able to concentrate or remember things.
Increased daytime fatigue is also reported more frequently in older people being treated for insomnia. These drugs also tend to affect psychomotor functions more in the elderly too. This refers to carrying out everyday tasks which involve coordinated movement, such as driving a car, playing an instrument, sewing or throwing a ball.
A study compared the effect of three hypnotics — including zopiclone 3.75mg and placebo — in 49 healthy volunteers aged 65 years and above.6 All active drugs were found to have a negative effect on balance and also reaction time on a test of memory. The effects of zopiclone were found to persist for 8-9 hours, suggesting a possibility of a reduction in function after waking the morning after a night-time dose.
What is stronger than zopiclone?
CONCLUSIONS – Chronic insomnia and pain are common interrelated comorbidities. There is a higher prevalence of chronic pain and insomnia in nonelderly adults compared to elderly patients. Regular opioid analgesic use is a risk factor for insomnia, but multimodal nonopioid analgesia may minimize insomnia.
Clonidine reliably provides and augments analgesia. Clonidine is significantly better than zopiclone with respect to analgesia, tolerability profile, and patient safety. Clonidine is significantly better than zopiclone in terms of overall sleep quality, total Likert sleep score, time to fall asleep, feeling rested on waking in the morning, and total sleep duration.
Further and larger clinical studies comparing clonidine with other insomnia medications would be beneficial.
Can I take zopiclone for anxiety?
Why Do You Get Withdrawal Symptoms? – Zopiclone works by increasing the activity of the neurotransmitter GABA. Since GABA is an inhibitory transmitter, which slows or stops the firing of other neurotransmitters, by increasing GABA activity you quiet the brain’s overall activity level.
GABA is the brain’s natural sedative, and zopiclone simply enhances its functioning. GABA suppresses excitatory neurotransmitters like dopamine, serotonin, epinephrine (noradrenaline) and acetylcholine. These excitatory transmitters play important roles in memory, muscle movement, alertness, emotional regulation, heart rate and blood pressure and hormonal secretions.
When taking zopiclone you quiet your whole brain’s activity level. This reduces anxiety and insomnia, but also causes changes to many of the body’s essential systems. This is why taking chronic high doses of zopiclone can cause such a variety of health problems and why people experience such a wide array of withdrawal symptoms after stopping.
Reduce the daily dose by half of a 3.75 mg tablet (1.875 mg) every 2 weeks. The target dose for when to stop is when the person is taking only half of a 3.75 mg tablet.

Can zopiclone 7.5 be halved?
Zopiclone 7.5mg tablets – Aurobindo Pharma – Milpharm Ltd. The tablet can be divided into equal doses.’
Which is stronger zolpidem or zopiclone?
In conclusion, zolpidem was at least as effective as zopiclone but showed significantly less rebound on withdrawal; overall it was better tolerated.
Can you wake up after taking sleeping pills?
Is it hard to wake up after taking sleeping pills? – Sleeping pills are not anesthetics. Most of the time, you would wake up naturally after taking them. However, it is important to time your sleep medicine properly to allow a full seven to eight hours of sleep. If you take a sleeping pill and wake up after only a few hours, you will likely feel groggy, off-balance, and confused.
Can you take zopiclone on a plane?
Due to a medical safety alert update we have received from Aviation trained doctors; we have been advised to no longer prescribe sedating drugs such as Diazepam, which is sometimes used to treat fear of flying, and medications such as Zopiclone, which is used as a sleeping tablet. There are several very good reasons why prescribing these drugs is not recommended:
Diazepam and Zopiclone are both sedative, which means it makes you more relaxed and sleepier. If there is an emergency during the flight, it may impair your ability to concentrate, follow instructions and react to the situation. This could have serious safety consequences not just to yourself, but to those around you. Sedative drugs can make you fall into an unnatural non-REM sleep. This means you won’t move around as much as you would do in natural sleep. This can cause you to be at increased risk of developing a blood clot in the leg (DVT) or even the lung. Blood clots are very dangerous and can even prove fatal. This risk is even greater if your flight is greater than 4 hours. Whilst most people find Diazepam sedating, a small number have paradoxical agitation and increased aggression. It can also cause disinhibition, leading you to behave in a way that you would not normally. This could impact on your safety as well as that of other passengers. A similar effect can be seen with alcohol, which has led to passengers being removed from their flights. It could also get you into trouble with the law. Diazepam and similar drugs are illegal in several countries. They may be confiscated, or you may find yourself in trouble with the police.
Given the above, we will no longer be prescribing Diazepam for flight anxiety or Zopiclone for flight insomnia. We appreciate that fear of flying is very real and very frightening. A much better approach is to tackle this properly with a Fear of Flying course run by the airlines. We have provided a number of these below:

What happens if you take 3 sleeping pills instead of 2?
Causes of Overdose – As sleeping pills work by depressing the central nervous system, the overuse of the drugs can slow body functions to such a degree as to cause unconsciousness, respiratory failure, and death. An overdose may be a deliberate suicide attempt.
- However, not all suicide attempts succeed as vomiting is common when the drug is taken in excess.
- If this happens, the person may survive but experience brain injury due to the lack of oxygen.
- By contrast, an accidental overdose can occur if someone takes too much of a sedative by mistake or combines it with other drugs that enhance the sleeping pills’ depressive effects.

What is an overdose of zopiclone?
Overdose – Zopiclone is sometimes used as a method of suicide. It has a similar fatality index to that of benzodiazepine drugs, apart from temazepam, which is particularly toxic in overdose. Deaths have occurred from zopiclone overdose, alone or in combination with other drugs.
- Overdose of zopiclone may present with excessive sedation and depressed respiratory function that may progress to coma and possibly death.
- Zopiclone combined with alcohol, opiates, or other central nervous system depressants may be even more likely to lead to fatal overdoses.
- Zopiclone overdosage can be treated with the GABA A receptor benzodiazepine site antagonist flumazenil, which displaces zopiclone from its binding site, thereby rapidly reversing its effects.
Serious effects on the heart may also occur from a zopiclone overdose when combined with piperazine, Death certificates show the number of zopiclone-related deaths is on the rise. When taken alone, it usually is not fatal, but when mixed with alcohol or other drugs such as opioids, or in patients with respiratory, or hepatic disorders, the risk of a serious and fatal overdose increases.
Is it OK to take 2 sleeping pills every night?
Sleeping pills are not meant to be taken every night. They are meant to be taken for short-term sleeping problems, such as jet lag. Long-term use is associated with risks such as diminished sleep quality, dependence, and more. Insomnia is the most common type of sleep disorder and it involves problems falling asleep or staying asleep despite adequate opportunity to do so.

Over-the-counter sleep aids: generally not recommended to treat chronic insomnia

How many hours apart should you take sleeping pills?
Skip to content Sleeping pills can be an effective treatment for chronic insomnia, But like any other drug, sleep medications can have side effects. One potential side effect of sleeping pills is daytime drowsiness. Sleep medications are powerful hypnotics.
They can be helpful because they cause a strong urge to sleep. But you don’t want this sleepiness to persist after you wake up. One way to minimize the risk of daytime drowsiness is to take a sleeping pill at the right time of night. Most sleeping pills – such as Ambien or Lunesta – should be taken right before you get in bed.
You should only take these sleeping pills when you are able to get a full night of sleep. This means that you should take the medication at least seven to eight hours before you need to wake up. But a new study shows that many people are taking sleeping pills in the middle of the night,
The researchers surveyed nearly 2,000 people who have a prescription for sleeping pills. Results show that 20 percent of respondents reported using a sleep medication in the middle of the night. Some of them even reported taking a sleeping pill twice in the same night. Taking a sleeping pill in the middle of the night greatly increases the risk of daytime drowsiness.
It also raises the risk that you will get out of bed without being fully awake. This may lead to problems such as “sleep driving.” Many people with insomnia wake up in the middle of the night and struggle to go back to sleep. This is called “sleep maintenance insomnia.” There is one sleeping pill that is FDA approved for sleep maintenance insomnia.
- Intermezzo can be taken in the middle of the night.
- You should take it when you have at least four hours of bedtime left.
- WARNING : Complex sleep behaviors such as sleepwalking or sleep driving can occur when you take a sleeping pill.
- Read this Consumer Update from the FDA to learn about these safety risks.
