Things to be careful of
This medicine will cause drowsiness. You should not operate dangerous machinery or drive motors for 12 hours after you take it. You should be careful the next morning when you wake up. Make sure you know how you react to this medicine before you drive a car or operate machinery. This is very important if you are taking other drugs that also make you drowsy.
Be careful if you are over 65 and unwell or taking other medicines. You may be more sensitive to some of the side effects of this medicine.
You should not drink alcohol while you are taking this medicine. The effects of alcohol could be made worse while taking this medicine.
If you have been addicted to alcohol or drugs in the past, it is important to tell your doctor before starting this medicine. Some medicines can cause dependence, especially when they are used regularly for longer than a few weeks. People who have been dependent on alcohol or other drugs in the past may have a higher chance of becoming addicted to sleep medicines.
Tell your doctor or pharmacist as soon as possible if you do not feel well while you are taking zopiclone.
All medicines can have side effects. Sometimes they are serious but most of the time they are not.
Do not be alarmed by the following lists of side effects. You may not experience any of them.
Tell your doctor if you notice any of the following:
- dry mouth, bitter taste in your mouth
- drowsiness, fatigue
Tell your doctor as soon as possible if you notice any of the following.
These may be serious side effects and you may need medical attention:
- nausea, vomiting and/or diarrhoea
- change in appetite
- stomach pain
- breathing difficulties
- depression, anxiety
- blurred vision
- sleep walking or other behaviours whilst asleep
- delirium (a sudden and severe change in mental state that can cause a combination of confusion, disorientation and/or attention deficit)
Alcohol can increase the risk of sleep walking or other behaviours such as driving or eating food whilst asleep. This risk is also increased if you take more than the recommended dose.
Some sleep medicines may cause a short-term memory loss. When this occurs, a person may not remember what has happened for several hours after taking the medicine. This is usually not a problem since most people fall asleep after taking the medicine.
Other side effects not listed above may occur in some patients.
