People with insomnia may be prescribed zopiclone by a doctor, especially when they face difficulty with sleep. Zopiclone belongs to a group of medications, known as ‘hypnotics’, that may act on the brain and produce the calming, sedating effect and support your full night’s rest. Below, we tell you what is zopiclone, why it is prescribed for sleep issues, its dosage considerations, and side effects.
Off-Label Uses and Applications of Zopiclone
Zopiclone is associated with treatment of insomnia, but clinicians also examined its use in other conditions. These are known as ‘off-label uses’. It means medicine that can also be used in a way that is not clinically prescribed. Some reported applications and uses include:
- Sleep Disruption: May be considered for sleep problems associated with other conditions.
- Temporary Sleep Changes: It may be used when normal sleep patterns are disrupted.
- Specialist Care: It may be considered in selected clinical situations under medical supervision.
- Clinical Research: Reported for sleep quality and hypnotic effects.
Effects of Zopiclone on Sleep Cycles: How it benefit?
Here are zopiclone’s effects on your sleep cycles:
- You may increase your sleep duration
- Improve your continuity of non REM sleep stages
- Decrease the frequency of nighttime awakenings
- Its long-term use should be avoided because it may change natural sleep cycles
- Promote deep stages of non-REM sleep (stages 3 and 4)
- Its prolonged use may cause lighter or less restorative sleep
How does Zopiclone Works: Mechanism of Action in the Brain
Zopiclone enhances the GABA activity, an inhibitory neurotransmitter in the central nervous system. It binds to GABA-A receptor sites and increases the calming effect on your brain activity. Can reduce the anxiety, mental hyperactivity and restlessness that prevent you from falling asleep. It also induces drowsiness, muscle relaxation and sleep onset. Our guide on how zopiclone works in the brain provides a clear explanation of its effects on the nervous system.
When Is Zopiclone Prescribed for Sleep: Dosage Instructions
The right dose of zopiclone depends on factors such as general health, age, liver or kidney function, and the person’s sensitivity to sedatives or other medicines. A prescribed adult dose is 7.5 mg and taken shortly before bed. Some people may also be prescribed the lower dose, around 3.75 mg. Older adults may be more likely to need a lower starting dose because it may cause sedation and falls.
Always follow the prescribed dose and instructions given by the doctor. General safety instructions for patients include:
- Take it before going to bed
- Ensure you stay in bed for a full night’s sleep
- Don’t take more than the prescribed dose
- Don’t take an extra tablet if you wake during the night unless a clinician has told you to do so
- Avoid alcohol, opioids, and other medicines that may cause drowsiness unless a pharmacist has confirmed that they can be used together
- avoid cycling, driving, operating machinery or safety-critical work for 12 hours after taking this medicine. Taking precautions becomes more important if you feel dizzy, sleepy, or less alert the following day
Side Effects Associated with Zopiclone Drug Interactions
Zopiclone interacts with other medications and causes increased side effects or reduced effectiveness. It may interact with:
-
Other Sleep Aids or Sedatives
Combining the sedatives with Zopiclone can enhance drowsiness and increase the risk of accidents or injuries.
-
Antidepressants and Antipsychotics
Interacting zopiclone with antidepressants and antibiotics can increase the risk of side effects. Inform your doctor about all medications you are taking and avoid harmful interactions.
-
Muscle relaxants
They may improve the sedative effects. It causes drowsiness and reduces muscle coordination. Recognise the potential serious reactions by reading our guide on zopiclone side effects.
Conclusion
Zopiclone is a prescription medicine that may provide short-term relief for insomnia, but it does not act as a permanent solution for poor sleep. You can take the lowest prescribed dose for the shortest duration, avoid alcohol and other sedatives, and address the reason for insomnia to reduce risks.
