Reviewed by the Kamcenuk medical content team · Last updated
Introduction
This category covers two opposite needs: zopiclone for short-term difficulty sleeping at night, and modafinil for excessive sleepiness during the day in conditions such as narcolepsy or shift-work sleep disorder. They are not interchangeable. General information only — not personal medical advice.
Insomnia — Signs and First Steps
- Trouble falling asleep despite feeling tired
- Waking often or lying awake for long periods
- Early morning waking without being able to return to sleep
- Daytime tiredness, irritability or poor concentration
First-line care is sleep hygiene: regular sleep/wake times, dark quiet bedroom, limiting caffeine/alcohol/screens in the evening, daytime activity and light. Short-term zopiclone may be considered when insomnia is severe and a clinician agrees a brief course is appropriate (typically days to 2–4 weeks only).
Zopiclone — Key Points
Zopiclone (e.g. Zopisign 10mg, Zopisign 7.5mg) enhances GABA calming activity to promote sleep. Risks include next-day drowsiness, dependence if used too long, and dangerous interaction with alcohol or other sedatives. Not a long-term solution.
Excessive Daytime Sleepiness — When Modafinil Is Considered
- Narcolepsy with overwhelming daytime sleepiness
- Shift-work sleep disorder affecting alertness on shift
- Residual sleepiness when obstructive sleep apnoea is already treated
Modafinil (e.g. Modafinil 100mg, Modafinil 200mg) promotes wakefulness but does not replace sleep. It can reduce the effectiveness of hormonal contraception — extra contraception is advised during use and for a period after.
Critical Safety
- Zopiclone: short-term only; no alcohol; care with driving next day
- Modafinil: contraception warning; specialist assessment for psychiatric or cardiac history
- Do not combine a sleeping tablet and a wakefulness tablet unless a doctor directs
- Both are prescription-context medicines in the UK

Final Takeaway

Frequently asked questions
Is zopiclone addictive?+
Tolerance and dependence can develop, so it is prescribed for short periods only and may need gradual reduction rather than abrupt stopping.
Does modafinil replace sleep?+
No. It promotes wakefulness but does not remove the body’s need for real sleep.
Can I take a sleeping tablet and a wakefulness tablet together?+
Only if a doctor specifically directs it. They treat opposite problems and should not be self-combined.
How does modafinil affect contraception?+
It can reduce hormonal contraception effectiveness. Use additional contraception during treatment and for a period after, as advised by a clinician.
How long can I take zopiclone?+
Usually only a few days to 2–4 weeks. It is not a long-term sleep solution.
What is sleep hygiene?+
Habits that support sleep: regular schedule, dark quiet cool bedroom, limited evening caffeine and screens, daytime activity and light.
When should I see a doctor about sleep?+
If insomnia lasts more than a few weeks, affects daytime function, or is linked to low mood, pain or breathing problems.
Is this medical advice?+
No. General information only. Consult a doctor or pharmacist before use.
