Insomnia is a common sleep disorder that affects millions of people worldwide. It can manifest as difficulty falling asleep, frequent nighttime awakenings, or early morning waking, leading to impaired daily functioning. One of the most effective pharmacological treatments for insomnia is Zopiclone, sold under the brand name Zimovane.
This article explores how Zopiclone works, its dosages (7.5 mg and 10 mg), its benefits, potential side effects, and important precautions to consider.

Understanding Insomnia and Its Impact
Insomnia is characterized by:
Difficulty falling asleep (sleep onset insomnia) – Taking more than 30 minutes to fall asleep.
Nighttime awakenings (sleep maintenance insomnia) – Waking up frequently during the night.
Early morning waking – Waking up too early and being unable to fall back asleep.
Chronic insomnia can lead to fatigue, poor concentration, mood disturbances, and reduced productivity. While lifestyle changes and cognitive behavioral therapy (CBT) are first-line treatments, medications like Zopiclone are often prescribed for short-term relief.
What is Zopiclone (Zimovane)?
Zopiclone is a non-benzodiazepine hypnotic agent that belongs to the cyclopyrrolone class. It is marketed under the brand name Zimovane and is primarily used for the short-term treatment of insomnia.
How Zopiclone Works
Zopiclone enhances the effect of gamma-aminobutyric acid (GABA), a neurotransmitter that inhibits brain activity. By binding to GABA receptors, Zopiclone induces sedation, relaxes the nervous system, and promotes sleep.
Key Benefits of Zopiclone
Rapid sleep onset – Helps users fall asleep faster.
Improved sleep maintenance – Reduces nighttime awakenings.
Prolonged sleep duration – Prevents early morning waking.
Restoration of natural sleep patterns – Enhances deep sleep (slow-wave sleep).
Zopiclone Dosages: 7.5 mg vs. 10 mg
Zopiclone is available in two primary strengths:
1. Zopiclone 7.5 mg
Standard recommended dose for most adults.
Effective for moderate to severe insomnia.
Should be taken immediately before bedtime.
Works within 30–60 minutes and lasts 6–8 hours.
2. Zopiclone 10 mg
Higher dose, sometimes prescribed for severe insomnia.
Used when Zopiclone 7.5 mg is insufficient.
Carries a higher risk of side effects (drowsiness, dizziness, dependency).
Generally prescribed for short-term use (2–4 weeks) to avoid tolerance.
Which Dosage is Right for You?
Elderly patients or those with liver impairment may require a lower dose (3.75 mg).
Adults with normal metabolism typically start at 7.5 mg.
Zopiclone 10 mg is reserved for severe cases under strict medical supervision.
How to Take Zopiclone Safely
To maximize benefits and minimize risks:
Take it right before bed – Avoid taking it earlier to prevent drowsiness while awake.
Avoid alcohol – Increases sedation and respiratory depression risk.
Short-term use only – Prolonged use can lead to dependence.
Do not crush or chew – Swallow the tablet whole for proper absorption.
Potential Side Effects of Zopiclone
While Zopiclone is effective, it may cause side effects, including:
Common Side Effects
Drowsiness (especially the next morning)
Bitter or metallic taste in the mouth (a distinctive side effect of Zopiclone)
Dry mouth
Dizziness or lightheadedness
Mild headache
Serious Side Effects (Rare but Require Medical Attention)
Memory loss (amnesia) – Especially if sleepwalking occurs.
Mood changes (depression, aggression)
Allergic reactions (rash, swelling, difficulty breathing)
Severe drowsiness affecting coordination
Precautions and Warnings
Who Should Avoid Zopiclone?
Pregnant or breastfeeding women – Risk of fetal harm.
People with severe respiratory disorders (e.g., COPD, sleep apnea).
Patients with myasthenia gravis (a muscle weakness condition).
Individuals with a history of drug abuse – High risk of dependency.
Risk of Dependence and Withdrawal
Tolerance can develop within weeks, making the drug less effective.
Abrupt discontinuation may cause rebound insomnia or withdrawal symptoms (anxiety, tremors, sweating).
Always taper off under medical supervision.
Natural and Behavioral Alternatives to Zopiclone
For long-term insomnia management, consider:
Cognitive Behavioral Therapy for Insomnia (CBT-I) – Addresses underlying sleep habits.
Sleep hygiene improvements – Regular sleep schedule, dark room, no screens before bed.
Relaxation techniques – Meditation, deep breathing exercises.
Melatonin supplements – Helps regulate sleep-wake cycles naturally.
Conclusion: Is Zopiclone Right for You?
Zopiclone (Zimovane) is an effective short-term solution for insomnia, particularly for those struggling with sleep onset and maintenance. The 7.5 mg dose is suitable for most adults, while 10 mg is reserved for severe cases.
However, due to risks of dependency and side effects, it should only be used under medical supervision and combined with behavioral therapies for lasting results.
If you suffer from chronic insomnia, consult a healthcare provider to determine if Zopiclone is appropriate for you or if alternative treatments may be better suited for long-term sleep improvement.
