How Long Will Zopiclone Make You Sleep?
If you have been prescribed zopiclone for insomnia, you may wonder how long zopiclone will make you sleep and how long its effects can last.
Zopiclone is a prescription sleeping medicine used for the short-term treatment of insomnia. It can help you fall asleep more quickly and may help reduce waking during the night. However, it does not make everyone sleep for exactly the same amount of time.
Zopiclone generally starts working within around 30 to 60 minutes. UK patient information also advises that you should have approximately 7 to 8 hours available for uninterrupted sleep after taking it. (NHS)
How Long Does Zopiclone Make You Sleep?
There is no fixed number of hours that zopiclone will make every person sleep.
The medicine is intended to help with falling asleep and maintaining sleep, but your actual sleep duration can depend on factors such as:
- Your age
- Your individual response to zopiclone
- The severity and type of insomnia
- Other medicines you take
- Alcohol consumption
- Your normal sleep pattern
- Other medical conditions
The NHS advises taking zopiclone shortly before going to bed and ensuring that you have enough time for a full night’s sleep. (NHS — Zopiclone)
If you are interested in the timing of the medicine, see our guide on how long before bed you should take zopiclone.
How Quickly Does Zopiclone Start Working?
Zopiclone usually begins to work relatively quickly.
According to the NHS, it generally takes approximately 30 to 60 minutes to start working. (NHS — Zopiclone)
For this reason, it is normally taken immediately before going to bed.

How Long Does Zopiclone Last?
The duration of zopiclone’s effects is not exactly the same as the time the medicine remains in your body.
The UK Summary of Product Characteristics reports an elimination half-life of approximately 5 hours in adults. Half-life describes how quickly the concentration of a medicine decreases in the body; it does not mean that someone will necessarily sleep for exactly five hours. (eMC — Zopiclone)
This is why questions such as “How long does zopiclone last?” and “How long will zopiclone make me sleep?” do not have exactly the same answer.

Why Is 7–8 Hours of Sleep Recommended After Zopiclone?
You may see 7–8 hours mentioned when reading about zopiclone.
This does not mean that zopiclone automatically puts everyone to sleep for exactly eight hours.
Instead, patient information advises that you should be able to get 7–8 hours of uninterrupted sleep after taking the medicine. This helps reduce the risk of being awake or active while the sedative effects are still present. (eMC Patient Information Leaflet)
Taking zopiclone when you have only a few hours available for sleep may increase the chance of feeling tired or less alert afterwards.
How Long Does Zopiclone 7.5mg Make You Sleep?
Zopiclone 7.5mg does not guarantee a specific sleep duration.
The response can vary between individuals. The prescribed dose and duration of treatment should be determined by a healthcare professional.
The UK prescribing information states that treatment should use the lowest effective dose for the shortest appropriate duration. (eMC — Zopiclone)
You should not increase the amount you take simply because you did not fall asleep as quickly as expected.
If you have already taken your prescribed dose and remain awake, do not automatically take another tablet during the same night. Follow the instructions provided by your prescriber or pharmacist.
Can Zopiclone Cause Next-Day Sleepiness?
Yes. Some people can experience tiredness, sleepiness, dizziness or reduced alertness the following day.
The NHS lists feeling tired, sleepy, dazed or less alert the following day among possible side effects. (NHS — Zopiclone)
The NHS also advises avoiding driving, cycling or operating machinery for 12 hours after taking zopiclone, and longer if you still feel affected. (NHS — Zopiclone)
If you regularly experience significant morning drowsiness, speak with your doctor or pharmacist.
What Can Make Zopiclone’s Effects Last Longer?
Several factors can influence how strongly or how long a person experiences the effects of zopiclone.
Age
Older adults can eliminate zopiclone more slowly, meaning that its effects may persist for longer.
Other medicines
Some medicines can increase the sedative effects of zopiclone. Tell your doctor or pharmacist about all medicines and supplements you use.
Alcohol
Alcohol can increase the sedative effects of zopiclone.

Liver or kidney problems
Certain medical conditions can affect how medicines are processed by the body. Your prescriber may therefore use a different dose when appropriate.
Individual response
People can react differently to the same medicine. Your experience may therefore differ from someone else’s.
What If Zopiclone Is Not Working?
If you have taken your prescribed zopiclone and you are still awake, do not assume that taking more will make it work better.
There can be several reasons why a person does not experience the expected effect, including underlying insomnia, other medicines, alcohol, stress, sleep habits and individual response.
If you are concerned that zopiclone is not working, speak with your doctor or pharmacist.

Can You Take Another Zopiclone If You Wake Up?
You should not automatically take another dose if you wake during the night.
UK prescribing information states that zopiclone should be taken as a single intake and should not be taken again during the same night. (eMC — Zopiclone)
If you regularly wake during the night despite taking your prescribed medicine, discuss this with your healthcare professional rather than changing the dose yourself.
How Long Should You Take Zopiclone?
Zopiclone is generally intended for short-term treatment of insomnia.
The NHS states that treatment usually lasts from a few days to a few weeks and is generally not prescribed for longer than four weeks because the body can become accustomed to it and the medicine may become less effective. (NHS — Zopiclone)
If you have been taking zopiclone regularly for a prolonged period, do not stop suddenly without discussing it with your healthcare professional.
Your doctor may recommend gradually reducing the dose.
