This is one of the most important questions anyone can ask about zopiclone, and the honest answer is: yes, zopiclone can be addictive — which is exactly why UK prescribing rules keep courses so short.
Tolerance: when the same dose stops working
Within a few weeks of regular use, the brain adapts to zopiclone and the same dose produces less effect. This is called tolerance. The temptation at that point is to take more — which is how problems begin. Never increase your dose yourself; if the prescribed dose has stopped helping, that’s a conversation for your GP, not a reason for an extra tablet.
Dependence: when the body relies on it
Dependence means the body has adjusted to the medicine’s presence, so stopping causes withdrawal symptoms. With zopiclone this can happen even at normal prescribed doses if taken for longer than recommended. Signs that dependence may be developing include:
- Feeling unable to sleep at all without a tablet;
- Needing a higher dose to get the same effect;
- Anxiety about running out, or requesting prescriptions early;
- Taking tablets during the day, or using them for anxiety rather than sleep;
- Getting tablets from more than one source.
Why short courses protect you
The 2–4 week limit — and the advice to use zopiclone only two or three nights a week where possible — exists precisely to prevent tolerance and dependence taking hold. It is a safety feature, not prescriber caution for its own sake.
If you think you’re dependent: what happens next
First, know this: dependence on prescribed sleeping tablets is common, treatable and nothing to be ashamed of. Do not stop suddenly — abrupt withdrawal can cause rebound insomnia, anxiety, shaking and, rarely, seizures after long-term use. Instead:
- Speak to your GP or pharmacist honestly about how much you are taking;
- Your prescriber can create a gradual tapering plan — see our guide to stopping zopiclone safely;
- Ask about CBT-i and other alternatives to zopiclone to treat the underlying insomnia;
- The NHS website and the charity Turning Point offer further support for prescription medicine dependence, and FRANK (talktofrank.com) provides confidential advice.

Frequently asked questions
How quickly can you become dependent on zopiclone?
Tolerance and dependence can begin within a few weeks of nightly use — which is why UK guidance limits courses to 2–4 weeks, ideally not every night.
What are zopiclone withdrawal symptoms?
After regular use, stopping suddenly can cause rebound insomnia, anxiety, restlessness, shaking, sweating and vivid dreams. Rarely, after long-term use, confusion or seizures — so stopping should be planned with your prescriber.
Is it addiction if I take it exactly as prescribed?
Dependence can develop even at prescribed doses if used for longer than recommended. It is a known effect of the medicine, not a personal failing — and your GP or pharmacist can help you taper off safely.
Where can I get help for sleeping tablet dependence?
Start with your GP or pharmacist — the conversation is confidential and common. The NHS website, Turning Point and FRANK (talktofrank.com) also offer information and support.
