  • you are breastfeeding or are planning to breast-feed
  • you are about to have any blood tests

  • Take your medicine to treat any other condition unless your doctor tells you to.
  • Drink alcohol before or after taking this medicine. Do not drink alcohol with this medicine.

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.

Impairment can occur despite feeling fully awake, in absence of symptoms or if you are feeling better.

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.

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 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. If you have been addicted to alcohol or drugs in the past, it is important to tell your doctor before starting this medicine.

Possible side effects

Tell your doctor as soon as possible if you do not feel well while you are taking zopiclone or if you have any questions or concerns.

Do not be alarmed by the following lists of side effects. You may not experience any of them. All medicines can have side effects. Sometimes they are serious but most of the time they are not.

Tell your doctor if you notice any of the following:

  • headaches
  • 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
  • rash
  • agitation
  • depression
  • confusion
  • anxiety
  • dizziness
  • blurred vision
  • impotence
  • sleep walking or other behaviours whilst asleep

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.

4 Clinical Particulars

4.9 Overdose

Overdose of zopiclone can be manifested by varying degrees of CNS depression ranging from drowsiness to coma according to the quantity ingested. In mild cases, symptoms include drowsiness, confusion and lethargy. In more severe cases, symptoms may include ataxia, hypotonia, hypotension, methaemoglobinaemia, respiratory depression and coma. Overdosage could be life threatening when combined with other CNS depressants, including alcohol. Other risk factors, such as the presence of concomitant illness and the debilitated state of the patient, may contribute to the severity of symptoms and very rarely can result in fatal outcome.
Treatment. Symptomatic and supportive treatment in an adequate clinical environment is recommended, attention should be paid to respiratory and cardiovascular functions. Activated charcoal may reduce absorption of the medicine if given within one or two hours after ingestion. In patients who are not fully conscious or have impaired gag reflex, consideration should be given to administering activated charcoal via a nasogastric tube, once the airway is protected. Haemodialysis is of no value due to the large volume of distribution of zopiclone. Flumazenil may be useful as an antidote. As in the management of overdosage with any medication, it should be borne in mind that multiple agents may have been taken.
For information on the management of overdose, contact the Poisons Information Centre on 13 11 26 (Australia).

5 Pharmacological Properties

5.3 Preclinical Safety Data

Genotoxicity. Genotoxicity studies, using a standard battery of tests, showed no evidence of gene mutations or chromosomal damage.
Carcinogenicity. Treatment with zopiclone by dietary administration for 2 years increased the incidence of thyroid carcinomas in male rats dosed with 100 mg/kg/day, and increased the incidence of mammary carcinoma in female rats dosed with 100 mg/kg/day, probably due to interference with thyroid hormone and 17β-estradiol metabolism. Studies with mice treated with zopiclone at dietary doses up to 100 mg/kg/day showed no evidence of drug-related carcinogenicity.
