Zopiclone belongs to the medium- and long-acting class of sleeping pills, with a drug maintenance time of up to 5-7 hours. The drug maintenance time will be shortened in some patients with persistent insomnia or long-term use of sleeping pills. Zopiclone belongs to benzodiazepines, which are central nervous system depressants with sedative, sleeping, anti-anxiety and anticonvulsant effects. This drug has adverse effects such as drug resistance, dependence and addiction. The duration of use should not be too long, generally not more than 4 weeks, can be used intermittently, when the drug must be gradually reduced. If the dose is too large, drowsiness, fatigue, dizziness, ataxia and other side effects may occur, and in serious cases, poisoning may occur. Insomnia is mostly caused by poor sleep. Cultivating good sleep habits can cure some insomnia patients. If you need to take oral sleeping medication, you need to use it under the guidance of a specialist and not to increase the dose of medication at will.
