General
Talk to your doctor or pharmacist before taking Zopiclone Grindeks.
Before starting treatment with Zopiclone Grindeks, the cause of your sleep problems should be investigated, and any other underlying disease treated.
Tell your doctor if you have or have had any illness or any other medical condition, especially if you:
- have liver or kidney problems
- have breathing problems
- have impaired general condition
- are elderly (in older people, medicines stay longer in the body)
- have depression or anxiety linked with depression
- have recently taken Zopiclone Grindeks or other similar medicines for more than 4 weeks.
Your doctor will decide whether you should take Zopiclone Grindeks or not or adjusts your dose. You will be also monitored closely during the treatment.
Talk to your prescriber before taking this medicine if you:
- are or have ever been addicted to opioids, alcohol, prescription medicines, or illegal drugs, or if you have ever had a history of struggling to control your alcohol or drug intake.
- have previously suffered from withdrawal symptoms such as agitation, anxiety, shaking or sweating, when you have stopped taking alcohol or drugs.
- feel you need to take more of Zopiclone Grindeks to get the same level of symptom control, this may mean you are developing tolerance to the effects of this medicine or are becoming addicted to it. Speak to your prescriber who will discuss your treatment and may change your dose or switch you to an alternative medication.
Taking this medicine regularly, particularly for a long time, can lead to physical dependence and addiction. Your prescriber should have explained how long you will be taking it for and, when it is appropriate to stop, how to do this safely. When your treatment is stopped, it is usually done gradually over a period which is specific to you and may occur over a period of weeks to months.
Physical dependence and addiction can cause withdrawal symptoms when you stop taking this medicine. Withdrawal symptoms can include:
- feeling anxious, shaky, irritable, agitated, confused, having panic attacks, sweating, headache, faster heartbeat or uneven heartbeat (palpitations), lower level of awareness or problems with focussing or concentrating, nightmares, seeing of hearing things that are not real (hallucinations), being more sensitive to light, noise and touch than normal, relaxed grip on reality, numbness and tingling in your hands and feet, aching muscles, stomach problems.
Your prescriber will discuss with you how to gradually reduce your dose before stopping the medicine. It is important that you do not stop taking the medicine suddenly as you will be more likely to experience withdrawal symptoms. Your prescriber will ensure that your plan for stopping treatment is tailored to you and can be adapted according to your needs and experience of any withdrawal symptoms.
Z-drugs should only be used by those they are prescribed for. Do not give your medicine to anyone else. Taking higher doses or more frequent doses of Z-drugs, may increase the risk of addiction. Overuse and misuse can lead to overdose and/or death.
Sleeplessness recurring after stopping the treatment (rebound insomnia)
If treatment is stopped abruptly after prolonged use, it sometimes leads sleeplessness for a few nights. This is a temporary syndrome called "rebound insomnia". To avoid any problems with discontinuation after long-term treatment, it is recommended to gradually reduce the dose. See also the section on side effects.
Short-term memory loss, so-called anterograde amnesia
Zopiclone Grindeks may cause a short-term memory loss, especially a few hours after taking the tablet. To reduce the risk of this, take Zopiclone Grindeks just before or after going to bed and make sure you will be able to have an uninterrupted sleep of 7–8 hours.
Psychiatric and "paradoxical reactions"
When using Zopiclone Grindeks, certain mental reactions, such as restlessness and anxiety, nightmares, irritability, aggression, inappropriate behaviour, hallucinations (seeing and hearing things that are not real), confusion, and difficulty concentrating may occur.
Sleepwalking, so-called somnambulism, and associated behaviours
Sleepwalking and other associated behaviours such as ‘sleep driving’, cooking and eating or making phone calls in your sleep, with memory loss of the event, have been reported in patients who have taken zopiclone and were not fully awake.
The risk of such behaviour increases if Zopiclone Grindeks is combined with alcohol or certain other specific medications (e.g., opioid-class painkillers, antipsychotics, hypnotics or anti-anxiety / sedatives). The risk also increases if Zopiclone Grindeks is taken in higher doses than the highest recommended dose. Contact a doctor immediately if you experience any of the above symptoms.
Depression/suicidal thoughts
This medicine is not intended to treat depression. If you also have a depression, your doctor will prescribe appropriate treatment. If depression is left untreated, it can worsen, become persistent or increase possible risk of suicide.
Some studies have shown an increased risk of suicidal thoughts, suicide attempts and suicides in patients taking certain sedatives and hypnotics, including this medicine. However, it has not been established if this is due to the medicine or if there are other reasons. If you have suicidal thoughts, contact your doctor as soon as possible for medical advice.
Risk of fall
Due to the muscle relaxing effect of zopiclone, there is a risk of fall, especially in the elderly when they get up during the night.
The treatment effect can be affected if Zopiclone Grindeks is taken at the same time as certain other medicines, which means that the dose of Zopiclone Grindeks may need to be adjusted.
Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines.
In particular any of the following medicines:
- Medicines for certain mental disorders (antipsychotics/neuroleptics)
- Sleeping pills (hypnotics)
- Medicines used to treat anxiety (anxiolytics)
- Medicines used to calm (sedatives)
- Treatment of depression (antidepressants)
- Strong opioid class painkillers, e.g., morphine and morphine-like substances
- Medicines used in surgery (anaesthetics)
- Medicines used to treat allergy (antihistamines)
- Some medicines used to treat bacterial and fungal infections such as erythromycin or itraconazole
- Medicines used to treat HIV infections
- Medicines used to treat epilepsy such as phenytoin, phenobarbital and carbamazepine
- Medicines used to treat tuberculosis (e.g., rifampicin)
- Products containing St. John's wort (traditional herbal medicine).
Concomitant use of Zopiclone Grindeks and opioids (strong pain killers, medicines for substitution therapy and some cough medicines) increases the risk of drowsiness, difficulties in breathing (respiratory depression), coma and may be life-threatening. Because of this, concomitant use should only be considered when other treatment options are not possible.
However, if your doctor does prescribe Zopiclone Grindeks together with opioids, the dose and duration of concomitant treatment should be limited by your doctor.
Please tell your doctor about all opioid medicines you are taking and follow your doctor’s dose recommendation closely. It could be helpful to inform friends or relatives to be aware of the signs and symptoms stated above. Contact your doctor when experiencing such symptoms.
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.
Pregnancy
Use of Zopiclone Grindeks is not recommended during pregnancy since it crosses the placenta. 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 in the newborn baby.
Reduced fetal movement and fetal heart rate variability may occur after taking Zopiclone Grindeks during the second and/or third trimester of pregnancy.
If Zopiclone Grindeks is taken at the end of pregnancy or during labour, your baby may show muscle weakness, a drop in body temperature, difficulty feeding and breathing problems (respiratory depression).
If this medicine is taken regularly in late pregnancy, your baby may develop physical dependence and may be at risk of developing withdrawal symptoms such as agitation or shaking. In this case the newborn should be closely monitored during the postnatal period.
Breast-feeding
Zopiclone passes into breast milk. Do not use Zopiclone Grindeks if you are breast-feeding.
