Insomnia, or poor sleep, is fairly common. There may be difficulty in falling asleep, waking during the night, or waking early in the morning.

Zopiclone is used for a short period of time to help sleeping difficulties. It reduces the time it takes to fall asleep and increases the length of time spent sleeping. Zopiclone works by acting on the way the messages are sent in your brain, which help you to sleep.

Zopiclone is not normally taken for more than 2-4 weeks. This is because your body gets used to this medicine and after a time it is unlikely to have the same effect. Your body may also become dependent on it when it is taken for longer periods of time.

Before taking zopiclone make sure your doctor or pharmacist knows:

  • If you are pregnant or breast-feeding.
  • If you have breathing problems or sleep apnoea (a problem where you stop breathing for short periods at night).
  • If you have kidney or liver problems.
  • If you have ever been dependent on drugs or alcohol.
  • If you have severe muscle weakness such as in myasthenia gravis.
  • If you have a mental health problem such as a personality disorder.
  • If you are taking other medicines, including those available to buy without a prescription, herbal and complementary medicines.
  • If you have ever had an allergic reaction to this or to any other medicine.
  • Before starting this treatment, read the manufacturer's printed information leaflet from inside the pack.
  • Take zopiclone exactly as your doctor has told you.
  • Take your dose just before going to bed.
  • If you forget to take a dose at bedtime, do not take it at any other time and do not take a double dose the next evening to make up.
  • Zopiclone is only recommended for short-term use, as the body gets used to this medicine quickly. It may be used for up to 4 weeks, but is often prescribed for much shorter periods. Do not take zopiclone for longer than your doctor tells you to, as your body could become dependent on it.
  • These tablets make you sleepy. If you still feel sleepy the next day, do not drive or use tools or machines.
  • You should avoid drinking alcohol while you are taking zopiclone as it may increase the risk of sleepwalking and doing other things which you are unable to remember when you awake.
  • When you stop taking zopiclone, your doctor may advise you to reduce the dose slowly to help prevent your sleep problems from returning. Follow any directions you are given and if you develop headaches, muscle pain, anxiety, tension, restlessness, confusion or irritability when you stop taking zopiclone, let your doctor know.
  • If you buy any medicines, check with a pharmacist that they are safe to take with zopiclone.
