Zopiclone and other drugs:

Tell your doctor if you are taking or have recently taken any of the following medicines, including medicines obtained without a prescription:

  • drugs to treat mental illness (antipsychotics)
  • medicines to treat depression, e.g. amitriptyline, fluoxetine and what are 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 tranquilizers, e.g. chlorpromazine strong pain relievers such as codeine, morphine. They can increase the feeling of excitement (euphoria), which in turn increases the possibility of physical or mental dependence.
  • medicines used to treat epilepsy, e.g. carbamazepine
  • anesthetics (used during surgery)
  • Antihistamine medicines that cause drowsiness, e.g. Alimemazine, Chlorphenamine
  • erythromycin (an antibiotic).

Concomitant use of zopiclone and opioids (strong analgesics, substitution therapy drugs and some cough medicines) increases the risk of drowsiness, shortness of breath (respiratory depression), coma and can be fatal. Therefore, concomitant use should only be considered when other treatment options are not possible.

However, if your doctor prescribes zopiclone along with opioids, he should limit the dose and duration of concomitant treatment.

The following medications may increase your risk of side effects when taken with zopiclone. To make this less likely, your doctor may lower your dose of zopiclone by:

  • some medicines for yeast infections like ketoconazole and itraconazole
  • some antibiotics, including erythromycin and clarithromycin
  • ritonavir (a protease inhibitor) used to treat HIV infections.

The following medications can make zopiclone work less well:

  • some epilepsy medicines, such as carbamazepine, phenobarbital, or phenytoin
  • rifampicin (an antibiotic) – for infections
  • St. John's wort (an herbal medicine): for mood swings and depression.
  • The effect of the following medicines is enhanced when taken with zopiclone: ​​muscle relaxants, e.g. baclofen
