It is a reasonable question, and one GPs hear every day. The surprising truth is that sleeping tablets often do not treat the underlying problem causing insomnia.
They may help some people in the short term, but they are usually not the best long-term solution. Here is why.
Sleeping tablet
May help for a few nights in selected situations, but does not usually rebuild sleep confidence or routine.
CBT-I
Works on the habits, thoughts and associations that keep insomnia going.
Sleeping Tablets Don't Create Natural Sleep
Many sleeping tablets do not produce sleep in the same way your brain naturally does. Instead, they sedate you.
That can help you fall asleep, but the quality of sleep is not always the same as natural sleep. Some people wake feeling groggy or less refreshed, even if they have spent longer in bed.
They Don't Treat The Cause
Insomnia is often driven by factors such as:
- Stress
- Anxiety
- Changes in routine
- Pain
- Poor sleep habits
- An overactive mind
- A disrupted body clock
A tablet may help you sleep for one night, but it does not address the reason your sleep became difficult in the first place.
Your Brain Can Become Dependent On Them
One of the biggest concerns is that your brain may start to believe: "I can't sleep without my tablet."
Over time, this can reduce your confidence in your own ability to sleep naturally. Some medicines can also lead to physical dependence if taken regularly, making them harder to stop.
They Often Become Less Effective
Many sleeping tablets lose their effect if they are taken regularly. People may then feel tempted to increase the dose, but this also increases the chance of unwanted side effects.
Side Effects Can Be Significant
Depending on the medication and the person taking it, sleeping tablets may cause:
- Morning drowsiness
- Poor concentration
- Memory problems
- Dizziness
- Falls, particularly in older adults
- Reduced driving ability the next day
For some people, these risks outweigh the potential benefits.
They Don't Improve Long-Term Sleep
Sleeping tablets may provide short-term relief for some people, but they do not usually solve chronic insomnia over months or years.
That is why national guidance recommends thinking differently about persistent insomnia.
So What Do Doctors Recommend Instead?
The treatment with the strongest evidence for long-term insomnia is Cognitive Behavioural Therapy for Insomnia, or CBT-I.
This is not "just talking about sleep". CBT-I helps people rebuild healthier sleep patterns, reduce anxiety around sleep, strengthen the link between bed and sleep, and improve sleep naturally over time.
For many people, the benefits last much longer than those from sleeping tablets.
Are Sleeping Tablets Ever Appropriate?
Yes. There are situations where a doctor may recommend a short course, for example:
- Following a sudden bereavement or major life event
- During a temporary period of severe stress
- Occasionally while other treatments begin to work
When they are prescribed, it is usually for a very short period: often just a few days, and rarely more than a couple of weeks.
The Bottom Line
Sleeping tablets can have a place, but they are usually a short-term tool rather than a long-term solution.
If you have been struggling with sleep for weeks or months, the most effective treatment is usually understanding what is keeping your brain awake and helping it rediscover how to sleep naturally.
Good sleep cannot usually be prescribed, but it can often be rebuilt.
Dr Mel's Notebook
Did you know?
People with chronic insomnia often worry that they have "forgotten how to sleep". In reality, the brain has often learned to associate bedtime with wakefulness and worry. That association can change.
Try this today
If you do not feel sleepy, do not rush to bed just because the clock says it is bedtime. Spend a little longer doing something relaxing in dim light, then go to bed when you genuinely feel sleepy.
The evidence
Guidance supports CBT-I for persistent insomnia. Sleeping tablets may help in selected circumstances, but are generally recommended only for short-term use because of limited long-term benefit and potential risks.
