1. What Zopiclone is and what it is used for
Zopiclone Tablets are benzodiazepine-like hypnotics, which work by acting on the brain to
cause sleepiness. They may be used for short term treatment of difficulty in sleeping which is
severe, disabling or causing great distress.

the face, lips, throat or tongue
• if you are allergic to any other benzodiazepines or benzodiazepine-like hypnotics, such as
nitrazepam or diazepam
• if you have severe liver problems. In patients with severe liver problems encephalopathy (a
brain disorder) may develop
• if you suffer from breathing problems whilst sleeping (sleep apnoea)
• if you suffer from severe muscle weakness (myasthenia gravis)
• if you have severe breathing problems or your lungs do not work properly
• if you are under the age of 18 years
Warnings and precautions

medicines used to treat sleep problems.

If you are elderly, you are more likely to experience certain of the side effects.

Please tell your doctor if you have any of the conditions listed above.
Other considerations:
• Dependence (a need to keep taking the medicine) – when taking this type of medicine there
is a risk of dependence, which increases with dose and length of treatment. This may be
physical dependence, where the body becomes used to the presence of the medicine and
stopping treatment causes withdrawal symptoms and/or mental dependence, where you
develop a craving for the medicine. There is a greater risk in patients with a history of
alcohol or drug abuse, of suffer from a personality disorder..
• Withdrawal – treatment should be withdrawn gradually. Withdrawal effects are unlikely
when duration of treatment is limited to 4 weeks. Withdrawal effects may also occur between
doses, especially if you are taking a high dose of Zopiclone. See Section 3, If you stop taking
• Amnesia – Zopiclone Tablets can cause memory loss. To reduce this risk you should ensure
that you are able to have 7-8 hours uninterrupted sleep.
• Behavioural effects may occur while taking Zopiclone (see Section 4, Possible side effects).
Blood test
• Zopiclone tablets can change the levels of liver enzymes shown up in blood tests. This can
mean that your liver is not working properly. If you are going to have a blood test, it is
important to tell your doctor that you are taking Zopiclone tablets.
Behavioural effects may occur while taking Zopiclone.
During the use of benzodiazepines and benzodiazepine-like substances, the following
psychiatric and paradoxical reactions may occur: restlessness, agitation, irritability,
aggression, having false beliefs that persist even with having evidence that the belief is not
true (delusions), outbursts of rage, nightmares, seeing, hearing or feeling things that are not
real (hallucinations), severe mental disorders characterized by disturbance of personality and
loss of contact with reality (psychoses), unsuitable behaviour, other behavioural disturbances.
The risk of these reactions is higher in elderly patients. If you feel any of the symptoms listed
above, you should stop taking Zopiclone. Ask your doctor for advice.
Sleep walking (somnambulism) and other associated behaviours such as “sleep driving”,
preparing and eating food, or making phone calls, with memory loss (amnesia) for the event,
have been reported in patients who have taken zopiclone and were not fully awake.
Other medicines and Zopiclone
Tell your doctor or pharmacist if you are taking or have recently taken any other medicines,
including medicines obtained without a prescription. Zopiclone Tablets may influence the
effect and/or side effects of other medicines. If you see another doctor or go into hospital,
particularly if you are having an operation under anaesthesia tell the doctor which medicines
you use.
The following medicine may increase the sedating effects of Zopiclone Tablets:
• medicines to treat mental illness (antipsychotics)

medicines to treat depression e.g. amitriptyline, fluoxetine, and those known as
monoamine oxidase inhibitors (MAOIs) e.g. phenelzine
other benzodiazepines or benzodiazepine-like hypnotics used to treat insomnia or anxiety
e.g. nitrazepam, diazepam
other tranquillizers e.g. chlorpromazine
some medicines for moderate to severe pain (narcotic analgesics) such as codeine,
methadone, morphine, oxycodone, pethidine, tramadol and morphine. Feelings of
excitement (euphoria) may increase, which in turn increase the chance of physical or
mental dependence
medicines used to treat epilepsy e.g. carbamazepine
anaesthetics (used during surgery)
antihistamine medicines which cause sleepiness e.g. alimemazine, chlorphenamine
erythromycin (an antibiotic)
medicines for hay fever, rashes or other allergies that can make you sleepy (sedative
antihistamines) such as chlorphenamine or promethazine

Zopiclone. To make this less likely, your doctor may lower your dose Zopiclone:
• Some medicines for fungal infections such as ketoconazole and itraconazole
• Some antibiotics including erythromycin and clarithromycin
• Ritonavir (a protease inhibitor) used to treat HIV infections
The following medicines can make Zopiclone work less well:
• Some medicines for epilepsy such as carbamazepine, phenobarbital or phenytoin
• Rifampicin (an antibiotic) – for infections
• St John’s Wort (a herbal medicine) – for mood swings and depression

liquid immediately before going to bed. The tablet should be swallowed whole. DO NOT
break, chew, or suck the tablet.

a day.
• Elderly patients, or those with liver or kidney problems, or breathing difficulties: a lower
dose of 3.75mg at night may be used. This dose may be increased to 7.5mg by your doctor

years of age
How long should you take Zopiclone Tablets?
Treatment with Zopiclone usually lasts from a few days to two weeks, up to a maximum of
four weeks, as directed by your doctor. Your treatment with Zopiclone should be for as short
a time and as low a dose as possible to reduce the risk of dependence occurring.

has swallowed any of the tablets, contact your nearest hospital casualty department or your
doctor immediately. Do not go unaccompanied to seek medical help.
An overdose is likely to cause drowsiness, sleeping deeply, confusion and lethargy. In more
serious cases, overdose may cause loss of co-ordination, muscle weakness, low blood
pressure (feeling dizzy and faint), breathing problems, falling over or losing your balance,
rarely coma and very rarely death. The effects of an overdose may be more severe if the
tablets have been taken with alcohol or other medicines such as antidepressants or sedatives.

doctor so that they know which tablets were consumed.
If you forget to take Zopiclone Tablets
If you forget to take a dose immediately before going to bed but remember during the night,
only take the missed dose if you will still be able to have 7-8 hours of uninterrupted sleep. If
this is not possible, take the next dose at the usual time the next night.

Do not take a double dose to make up for a forgotten dose. If you are worried ask your
pharmacist or doctor for advice.
If you stop taking Zopiclone Tablets
When your doctor decides to stop your tablets, the dose will be reduced gradually over a
period of time. DO NOT stop taking your tablets suddenly.
Stopping Zopiclone may lead to “re-bound insomnia”. This means the symptoms that required
you to take your tablets in the first place may reappear and be more severe for a short time.
These symptoms may also be accompanied by mood changes, sleeping difficulties, anxiety
and restlessness. Therefore, the dose of these tablets must always be reduced gradually.
These effects will disappear in time.
If you have become physically dependent on Zopiclone Tablets, sudden withdrawal of
treatment will lead to side effects such as headaches, tremor, sweating, agitation, fast heart
beat (palpitations), uneven heartbeat (tachycardia), relaxed grip on reality, panic attacks,
stomach problems, muscle pain, tension, restlessness, confusion, sleeping difficulties,
nightmares, a lower level of awareness and problems with focusing or concentrating and
In severe cases other effects may appear, such as:
• hypersensitivity to light, noise and physical contact
• sounds seeming louder than usual, and painful sensitivity to sound
• hallucinations
• numbness and tingling in the fingers and toes
• derealisation (feeling the world around you is not real)
• a feeling of detachment from your surroundings
• depersonalisation (feeling your mind is becoming separated from your body)
• epileptic seizures (violent fitting or shaking).
These symptoms may also be experienced between doses, especially if the dose is high.
If you have any further questions on the use of this product, ask your doctor or pharmacist.
