Zopiclone is a prescription sleep aid used to treat short-term insomnia. When used correctly under medical supervision, it can be highly effective — but like all sleep medicines, it comes with important safety considerations every patient should understand before their first dose.
Millions of people across the UK struggle with insomnia at some point in their lives. When sleep hygiene adjustments and behavioural techniques aren't enough, a doctor may prescribe zopiclone tablets to help restore restful sleep. This guide walks you through everything you need to know to use zopiclone safely, responsibly, and as effectively as possible.
What Is Zopiclone?
Zopiclone belongs to a class of medicines called cyclopyrrolones — sometimes grouped informally with "Z-drugs" alongside zolpidem and zaleplon. It works by enhancing the effect of GABA, a calming neurotransmitter in the brain, helping you fall asleep faster and stay asleep longer. According to the NHS, zopiclone is only available on prescription and is not intended for long-term use.

Top Tips for Taking Zopiclone Safely
Take It Exactly as Prescribed
Never adjust your dose without speaking to your doctor. The standard 7.5 mg dose is right for most adults, but elderly patients or those with liver problems are typically started on 3.75 mg to minimise side effects.
Only Take It When You Have 7–8 Hours Ahead
Zopiclone causes drowsiness that can persist into the next morning. Never take it if you need to drive, operate machinery, or be fully alert within eight hours of taking the tablet. NHS guidance is clear on this point.
Take It Immediately Before Bed
Swallow the tablet just as you get into bed. Taking it earlier — while still sitting, watching TV, or eating — increases the risk of falls and memory gaps before sleep begins.
Do Not Crush or Chew the Tablet
Swallow zopiclone whole with a glass of water. Crushing or splitting the tablet can alter how quickly it is absorbed and increase the risk of side effects. Check our FAQ page for common dosage questions.
Avoid Alcohol Completely
Combining zopiclone with alcohol significantly intensifies sedation and can dangerously slow your breathing during sleep. Even a small amount of alcohol should be avoided on any night you plan to take zopiclone.
Stick to the Shortest Course Necessary
Zopiclone is designed for short-term use only. The longer you take it, the greater the risk of dependence and tolerance. Read more about zopiclone for insomnia on our blog.
Never Double Up a Missed Dose
If you forget to take your dose and it is no longer close to bedtime, skip it entirely. Taking a double dose to compensate is dangerous and can cause prolonged sedation into the following day.
Store It Safely Away from Children
Keep zopiclone in its original packaging, at room temperature, away from light and moisture — and always well out of reach of children. Never share your prescription with anyone else.
Know the Drug Interactions
Zopiclone interacts with several common medicines and substances. Always give your doctor and pharmacist a complete list of everything you are taking — including over-the-counter medicines, herbal supplements, and recreational substances. The Electronic Medicines Compendium (EMC) is a reliable resource for full interaction data.
Alcohol: Dangerous respiratory depression risk. Opioid painkillers (codeine, tramadol, morphine): Severe risk of breathing difficulties. Other sedatives, antidepressants, or antipsychotics: Additive sedation. Antihistamines (e.g., chlorphenamine): Increased drowsiness. Erythromycin, ketoconazole: Can raise zopiclone blood levels. Always consult your doctor or pharmacist before combining any medicine. Read our full FAQ for more guidance.
Common Side Effects and What to Do About Them
Most people tolerate zopiclone well at the recommended dose. According to WebMD's zopiclone overview, being aware of possible side effects helps you respond appropriately if they occur.
- Bitter or metallic taste in the mouth — very common; drinking water or brushing teeth can help
- Drowsiness the next morning — avoid driving or using machinery until you feel fully alert
- Dry mouth — stay well hydrated before bed
- Dizziness or light-headedness — rise slowly from bed; use handrails on stairs
- Memory problems or confusion — report to your doctor, especially if persistent
- Sleepwalking or unusual behaviour during sleep — stop the medicine and contact your doctor immediately
Difficulty breathing or shallow breathing during sleep, severe confusion or hallucinations upon waking, signs of an allergic reaction (rash, swelling of the face/lips/throat), or unusual mood changes such as aggression or depression. Do not wait — contact emergency services or your prescriber right away. You can also reach our support team at buyzopicloneuk.to/contact.
Understanding Dependence and How to Stop Safely
Physical and psychological dependence can develop with zopiclone, even at therapeutic doses, particularly when used for more than four weeks. The NICE guidelines on insomnia recommend the shortest possible course at the lowest effective dose. Signs of dependence include needing the medicine to feel "normal," experiencing anxiety when a dose is missed, and finding that you need higher doses to achieve the same sleep quality.

How to Stop Zopiclone Without Rebound Insomnia
Abruptly stopping zopiclone can cause rebound insomnia — where sleep difficulties temporarily worsen. The safest way to stop is a gradual taper under your doctor's guidance:
- Week 1–2: Reduce from 7.5 mg to 3.75 mg nightly
- Week 3: Take 3.75 mg on alternate nights
- Week 4: Take 3.75 mg two or three times per week
- Week 5 onwards: Stop completely, supported by good sleep hygiene
Who Should Not Take Zopiclone?
Zopiclone is not suitable for everyone. Your doctor will review your medical history before prescribing. For a full breakdown, visit our FAQ page or read our dedicated article on zopiclone use during pregnancy. The following groups should generally avoid it:
- People with a history of alcohol or drug dependence
- Those with severe liver or kidney disease
- People with sleep apnoea or other breathing disorders
- Pregnant or breastfeeding women — see our article: Can Pregnant Women Take Zopiclone?
- Children and adolescents under 18
- People with myasthenia gravis (a muscle weakness condition)
- Those with a history of psychosis or severe mental health conditions
Zopiclone works best when it is part of a broader approach to improving sleep — not used as a standalone solution. The Sleep Foundation recommends rebuilding healthy sleep habits during your prescription period so that when you stop the medicine, your sleep can sustain itself.
Keep a Consistent Sleep Schedule
Go to bed and wake up at the same time every day — even on weekends. This anchors your circadian rhythm and makes falling asleep naturally much easier over time.
Limit Screen Time Before Bed
Blue light from phones and screens suppresses melatonin. Switch off devices at least 45–60 minutes before your intended bedtime to help your brain shift into sleep mode.
Keep Your Bedroom Cool and Dark
Your body temperature needs to drop slightly to initiate sleep. A cool, dark room — ideally between 16–19°C — creates the optimal environment for deep, restorative sleep.
Consider CBT-I (Cognitive Behavioural Therapy for Insomnia)
CBT-I is the most evidence-backed long-term treatment for insomnia according to NICE. Ask your GP or a sleep clinic about accessing it alongside or instead of medication.
