Zopiclone is one of a group of medicines called hypnotics (sleeping tablets). These tablets can be used for both temporary and longer lasting sleep problems (insomnia). It should help you to sleep, without leaving you drowsy the next day.

However, Zopiclone is not meant to be used every day for long periods of time. If you need any further information on your condition, please ask your doctor.


Do not take Zopiclone if:

  • You are allergic to Zopiclone or any of the other ingredients of this medicine (listed in section 6). Signs of an allergic reaction include: a rash, swallowing or breathing problems, swelling of your lips, face, throat or tongue.
  • You suffer from myasthenia gravis (a condition where the muscles easily tire and become weak)
  • You suffer from sleep apnoea
  • You suffer from respiratory failure (your lungs do not work properly)
  • You have severe liver problems
  • You are under 18 years of age

Do not take this medicine if any of the above applies to you. If you are not sure, talk to your doctor or pharmacist before taking Zopiclone.

Warnings and precautions

Talk to your doctor or pharmacist before taking Zopiclone if you:

  • have a personality disorder
  • have ever been, or are currently being treated for drug or alcohol abuse
  • have any kidney or liver problems - your doctor may need to give you a lower dose
  • feel you will not be able to stop taking Zopiclone or any medication used to treat your sleep problems
  • have recently taken Zopiclone or other similar medication for more than 4 weeks
  • are elderly as there may be a greater risk of side effects
  • have or have ever had depression or any other mental illness
  • suffer from mild breathing problems (your doctor will decide if you should take Zopiclone)

Before taking Zopiclone Tablets, ensure that you can have an uninterrupted sleep of 7 to 8 hours, to help reduce the side effect of poor memory (see section 4).

Please tell your doctor about all opioid medicines you are taking and follow your doctor’s dosage recommendations closely.

Some studies have shown an increased risk of suicidal ideation, suicide attempt and suicide in patients taking certain sedatives and hypnotics, including this medicine. However, it has not been established whether this is caused by the medicine or if there may be other reasons. If you have suicidal thoughts, contact your doctor as soon as possible for further medical advice.

Use of Zopiclone may lead to the development of abuse and /or physical and psychological dependence. The risk of dependence increases with dose and duration of treatment and is greater when Zopiclone is used for longer than 4 weeks, and in patients with a history of mental disorders and/or alcohol, illicit substance or drug abuse. Tell your healthcare provider if you have ever had a mental disorder, or have abused or have been dependent on alcohol, substance or drugs.

Children and adolescents

Do not give this medication to children or adolescents under 18 years of age as the safety has not yet been established in this group.

Other medicines and Zopiclone

Please inform your doctor or pharmacist if you are taking, or have recently taken, any other medicines including medicines obtained without a prescription. If you are taking any other medicines, these medicines may change the way Zopiclone Tablets work.

  • treatment for schizophrenia and psychotic disorders (antipsychotics)
  • treatment for depression
  • treatment for epilepsy such as carbamazepine, phenobarbital or phenytoin
  • strong pain killers such as codeine, morphine, methadone, oxycodone, pethidine, tramadol or diamorphine

If you have to go to a doctor, dentist or hospital, for any reason, tell them that you are taking Zopiclone Tablets.

Zopiclone with alcohol

Do not drink alcohol while you are taking this medicine. Alcohol can increase the effects of Zopiclone and make you sleep very deeply so that you do not breathe properly or have difficulty waking.

Pregnancy and breast-feeding

If you are pregnant or breast-feeding, think you may be pregnant or are planning to have a baby, ask your doctor or pharmacist for advice before taking this medicine. If used during pregnancy there is a risk that the baby is affected. Some studies have shown that there may be an increased risk of cleft lip and palate (sometimes called “harelip”) in the newborn baby.

Reduced fetal movement and fetal heart rate variability may occur after taking Zopiclone during the second and/or third trimester of pregnancy.

Do not take this medicine during the last 3 months of pregnancy or during labour because it may be harmful to your baby. If taken in late pregnancy, the baby may have muscle weakness, low body temperature, difficulty feeding, breathing difficulties and show withdrawal symptoms such as agitation or shaking after birth because of physical dependence. In this case the newborn should be closely monitored during the postnatal period.


Do not take Zopiclone if you are breast-feeding or planning to breast-feed. This is because small amounts may pass into mother’s milk. If you are breast-feeding or planning to breast-feed, talk to your doctor or pharmacist before taking any medicine.

Driving and using machines

Like other medicines used for sleep problems, Zopiclone can cause slowing of your normal brain function (central nervous system depression). The risk of psychomotor impairment including driving ability is increased if:

  • You take Zopiclone within 12 hours of preforming activities that require mental alertness
  • You take higher than the recommended dose of Zopiclone
  • You take Zopiclone while already taking another central nervous system depressant or another medicine that increases the levels of Zopiclone in your blood, or while drinking alcohol.

On the day after taking Zopiclone 7.5mg Tablets, do not drive or use machinery or tools if you feel sleepy, dizzy or confused.

For more information about possible side effects, which could affect your driving, see section 4 of this leaflet.

Zopiclone contains Lactose

This medicine contains lactose. If you have been told by your doctor that you have an intolerance to some sugars, contact your doctor before taking this medicine.


Always take this medicine exactly as your doctor has told you. Check with your doctor or pharmacist if you are not sure. The number of tablets you need to take will depend on your condition.

Zopiclone Tablets should be swallowed whole without sucking, chewing or crushing, with a small glass of water before you go to bed.

The usual adult dose is one Zopiclone Tablet (7.5mg) per day.


The usual starting dose is 3.75mg (½ a tablet).

Patients with liver or kidney problems

The usual starting dose is 3.75mg (½ a tablet).

A reduced dosage is recommended

Use in Children and adolescents

Zopiclone Tablets are NOT recommended for children.

Your treatment will usually be for less than 4 weeks, and the doctor may reduce your dose near the end of your course. If you take Zopiclone longer than this, the medicine may not work as well, you may become dependent and you may have withdrawal symptoms when you stop.

If you have the impression that the effect of Zopiclone Tablets is too strong or too weak talk to your doctor or pharmacist.

If you take more of this medicine than you should

If you have taken more Zopiclone Tablets than you should, or a child swallows any tablets, go to your nearest casualty department immediately. Take the medicine pack with you so the doctor knows what you have taken.

Taking too much Zopiclone can be very dangerous. The symptoms of overdose include feeling drowsy, shallow breathing or difficulties breathing and difficulty in controlling movements.

If you forget to take your medicine

Zopiclone must only be taken before going to bed. If you forget to take a dose just take the next tablet at the usual time. DO NOT take two doses at the same time.

If you stop taking this medicine

It is important to continue taking the tablets for as long as your doctor tells you to. You should not stop taking your tablets suddenly without advice from your doctor. Do not change the dose of your medicine unless you have spoken with your doctor.

Your doctor will need to lower your dose before stopping your treatment to help prevent any withdrawal effects and to help prevent return of your sleep problems (rebound insomnia).

Stopping treatment with Zopiclone Tablets is unlikely to be associated with withdrawal effects when duration of treatment is limited to 4 weeks.
