Of all the warnings that come with zopiclone, this is the one pharmacists repeat most often: do not drink alcohol while taking it — at all. Here’s why the rule is absolute, not cautious small print.
Why the combination is dangerous
Zopiclone and alcohol are both central nervous system depressants — they slow brain activity. Taken together, their effects do not simply add up; they amplify each other. The result can include:
- Very deep, abnormal sleep from which it may be difficult to wake.
- Slowed or interrupted breathing, which can be life-threatening — especially for people with sleep apnoea or other breathing problems.
- A much higher risk of sleepwalking and complex sleep behaviours: eating, making calls, leaving the house or even driving while not fully awake, with no memory afterwards.
- Worse memory loss, confusion and falls, particularly in older adults.
“Just one drink” is not safe
There is no established safe amount of alcohol to combine with zopiclone. Because alcohol also disrupts sleep quality in the second half of the night, drinking undermines the very thing the tablet is prescribed for. If you drink regularly, tell your prescriber before starting zopiclone — this is a safety conversation, not a judgement, and it may change which treatment is right for you.
What if I’ve already had a drink?
If you have been drinking, skip your zopiclone dose that night. Missing one dose is far safer than combining the two. Never take the missed dose later in the night or double up the next day.
When to get emergency help
Call 999 immediately if someone who has mixed zopiclone and alcohol:
- Cannot be woken, or is unusually difficult to rouse;
- Has slow, shallow or noisy breathing;
- Has blue-tinged lips or fingertips.
Stay with them, lie them on their side if possible, and take the medicine packaging to hospital.
A note on other sedatives
The same amplifying effect applies to other sedating substances — opioid painkillers, some antidepressants and antihistamines, and recreational drugs. Always tell your pharmacist everything you take so we can check interactions. Read more in our guide: who should not take zopiclone.
Frequently asked questions
How long after drinking alcohol can I take zopiclone?
There is no officially safe gap, because alcohol can remain active in your body for many hours. If you have been drinking that evening, skip that night’s dose entirely — missing one dose is always safer.
Can I have one small drink with zopiclone?
No. There is no established safe amount of alcohol with zopiclone. Even small amounts amplify sedation and raise the risk of breathing problems and sleepwalking behaviours.
What are the signs of a dangerous reaction?
Being unusually difficult to wake, slow or shallow breathing, snoring or gurgling sounds, and blue-tinged lips or fingertips. Call 999 immediately and stay with the person.
