Zopiclone is a prescription sleeping medicine for short-term treatment of severe insomnia in adults. It may help people fall asleep and reduce waking during the night. Treatment should be brief because tolerance, dependence and withdrawal can occur. Compare products by strength, manufacturer, pack size and prescription status.


Zopiclone is a Z-drug that strengthens the calming action of gamma-aminobutyric acid (GABA) in the brain, helping sleep begin and continue.
It treats symptoms, not the underlying cause. Stress, pain, mental-health conditions, sleep apnoea and poor sleep habits may require separate treatment.
A commonly licensed adult zopiclone dosage is 7.5 mg once shortly before bedtime. A 3.75 mg starting dose may be prescribed for older adults or people with liver, kidney or breathing problems. Follow the applicable label and prescription.
Take one prescribed dose per night only when able to sleep for seven to eight hours. Do not redose after waking. Treatment generally should not exceed four weeks, including withdrawal, without reassessment.
Never increase the dose or stop regular treatment suddenly; a prescriber should plan any reduction.
Common zopiclone side effects include:
A bitter or metallic taste
Dry mouth
Daytime sleepiness or reduced alertness
Dizziness or headache
Nausea or digestive discomfort
Nightmares or unusual dreams
Zopiclone can impair memory, balance and coordination. Do not drive or use machinery until the label-specified period has passed and you feel alert; some labels advise avoiding these activities for 12 hours after a dose.
Seek urgent help for slow breathing, inability to wake, collapse, seizure, severe confusion, facial or throat swelling, or thoughts of self-harm. Report sleepwalking, sleep-driving or another activity performed while not fully awake immediately.
People researching long term use of zopiclone side effects should know that extended use can cause tolerance and physical or psychological dependence. Risk rises with the dose and treatment duration.
Sudden stopping may cause rebound insomnia, anxiety, sweating, headache, irritability or confusion. Severe withdrawal can include hallucinations or seizures. Sedation, memory problems and falls are additional concerns.
Do not take more tablets when the effect decreases. Ask the prescriber to review treatment and plan any reduction.
The comparison zopiclone vs zolpidem involves two prescription Z-drugs for short-term insomnia. Both affect GABA and can cause next-day impairment, dependence, withdrawal and complex sleep behaviours.
Zopiclone is used for difficulty falling or staying asleep and remains in the body longer on average. Immediate-release zolpidem is primarily labelled for difficulty starting sleep. Neither is universally better or safer.
For zopiclone vs zolpidem dosage, the milligram numbers are not equivalent. A commonly licensed zopiclone dose is 7.5 mg nightly, with 3.75 mg used for some higher-risk patients. Current US immediate-release zolpidem labelling starts at 5 mg for women and 5 or 10 mg for men; 5 mg is recommended for older adults and certain liver conditions.
These are label differences, not a conversion method. Never combine, substitute or switch these medicines without a prescriber.
Zopiclone vs Ambien is the same comparison because Ambien is a brand of zolpidem, not zopiclone. Formulation, response, interactions and next-day responsibilities influence selection.
Never combine zopiclone with alcohol, another sleeping tablet or a recreational sedative.
Opioids and other central nervous system depressants can cause profound sedation, respiratory depression, coma or death when combined with zopiclone.
Disclose sleep apnoea, breathing problems, severe liver disease, myasthenia gravis, depression and any history of medicine or alcohol dependence.
Discuss pregnancy, plans to conceive or breastfeeding before treatment.
Take the tablet only at bedtime, swallow it as directed and never share it.
Store it securely away from children and anyone for whom it was not prescribed.

Only for the prescribed short period. Nightly treatment should not continue without reassessment because dependence and tolerance can develop.
