How It Works
Zopiclone acts on calming receptors in the brain called GABA (gamma-aminobutyric acid) receptors.
By strengthening these natural sleep signals, it slows over-active brain activity and brings on sleep more easily.
It doesn’t knock you out cold, but rather helps your body settle into a normal sleep rhythm.
The effects usually start within 30 minutes, so it’s best taken right before bed.
Typical Use and Dosage
Zopiclone is taken by mouth just before bedtime.
-
The usual adult dose is one 7.5 mg tablet once nightly.
-
Older adults or those with liver or kidney issues may be prescribed a smaller 3.75 mg dose.
-
Swallow the tablet whole with water.
-
Make sure you can stay in bed for at least 7–8 hours afterwards; getting up too soon can cause drowsiness or clumsiness.
This medicine is meant for short-term use only — normally no more than two to four weeks — to avoid dependence or reduced effect over time.
If your sleep doesn’t improve after that, speak to your GP rather than continuing on your own.
Common Effects and How It Feels
Most people describe zopiclone as bringing on a gentle, calm sleep.
It can leave a slightly bitter or metallic taste in the mouth the next day — that’s quite normal.
A bit of grogginess or dry mouth can also happen at first, though these usually ease as your body adjusts.
Possible Side-Effects
Common side-effects include:
-
Drowsiness or dizziness the following morning
-
Dry mouth or metallic taste
-
Headache or light-headedness
Less common but more serious effects can include memory problems, confusion, hallucinations, or allergic reaction (swelling, rash, breathing difficulty).
If you notice anything unusual, stop taking it and contact a doctor right away.
Precautions and Warnings
Zopiclone isn’t suitable for everyone.
Tell your doctor or pharmacist if you:
-
Have liver, kidney, or breathing problems such as sleep apnoea
-
Have a history of depression, anxiety, or alcohol misuse
-
Are pregnant, planning to be, or breastfeeding
-
Need to drive or use machinery early the next morning — it may still make you sleepy
Avoid alcohol while taking zopiclone, as it intensifies drowsiness and increases risk of accidents.
If you’ve been taking it for a while, don’t stop suddenly; the dose should be reduced gradually to prevent rebound insomnia.
