Understanding Sleeping Pills: Are They the Right Choice for You?

What Are Sleeping Pills?

Sleeping pills are medications designed to help individuals fall asleep, stay asleep, or both. They are broadly classified into two categories:

1. Prescription sleeping pills (e.g. Zopiclone, Diazepam)

2. Over-the-counter (OTC) sleep aids (e.g. Nytol, Sominex, herbal remedies)

   
   

Each category works differently, with varying levels of effectiveness and risk.

Types of Sleeping Pills in the UK

Prescription Medications

Prescription sleeping tablets are generally stronger than over-the-counter options. They are usually prescribed only for short-term use under medical supervision. In the UK, doctors most commonly prescribe Z-drugs such as zopiclone and zolpidem. These medications act quickly and are typically used to manage short-term insomnia.

Benzodiazepines, including diazepam and temazepam, may also be prescribed. However, their use is increasingly limited due to the risk of dependence, tolerance, and cognitive side effects. Melatonin is sometimes prescribed, particularly for older adults or for individuals with circadian rhythm issues such as delayed sleep phase disorder.

Over-the-Counter Options

Over-the-counter sleep aids are widely available in UK pharmacies and through online retailers. These commonly include diphenhydramine-based products, such as Nytol Original, which use a sedating antihistamine to promote drowsiness.

Herbal sleeping pills are also popular, with ingredients like valerian root, passionflower, and hops often used to support relaxation and sleep. Although melatonin supplements are readily available in many other countries, melatonin cannot be purchased over the counter in the UK and is only legally available with a prescription.

Short-Term Benefits of Sleeping Pills

Sleeping pills can help in the short term with travel-related sleep issues like jet lag.

Sleeping pills can be helpful in certain short-term situations. They are particularly useful when sleep disruption is caused by acute stress, grief, travel, or major life events. They are also sometimes used to manage temporary sleep disturbances related to jet lag or shift work.

When taken as prescribed and for limited periods, sleeping tablets can provide short-term relief. They may help stabilise a disrupted sleep pattern while underlying issues are addressed.

Risks and Side Effects: Are They Bad for Long-Term Use?

1. Dependence and Withdrawal

One of the biggest concerns with sleeping pills, particularly prescription options such as zopiclone or diazepam, is the risk of both physical and psychological dependence. With continued use, tolerance can develop, meaning higher doses may be needed to achieve the same effect. Stopping suddenly can lead to withdrawal symptoms, especially after regular use. Some people may also develop a psychological reliance on taking a tablet to fall asleep.

The NHS advises that sleeping tablets should be used for no more than 1 to 2 weeks for this reason.

2. Next-Day Drowsiness

Many people report feeling groggy or experiencing a hangover effect the morning after taking sleeping pills. This is particularly common with longer-acting medications such as zopiclone. These can linger in the system and impair next-day functioning. As a result, driving ability, memory, and overall cognitive performance may be reduced, increasing the risk of accidents and reduced productivity the following day.

3. Falls and Injuries in Older Adults

Sedative medications are associated with an increased risk of falls, particularly in older adults. A 2022 meta-analysis published in Age and Ageing found that benzodiazepine users had a 44% increased risk of hip fractures.

4. Cognitive Impairment and Dementia

Long-term use of benzodiazepines has been linked to cognitive decline and possibly dementia. The British Medical Journal published a 2021 study indicating a dose-dependent risk, particularly with prolonged use over several months.

5. Interactions with Other Medications

Sleeping pills can interact negatively with alcohol, antidepressants, antihistamines, and painkillers. This can lead to potentially dangerous effects like respiratory depression.

6. Rebound Insomnia

When individuals stop taking sleeping pills, they often experience a worsening of their sleep problems. This is known as rebound insomnia, and it can create a cycle of dependence and poor sleep quality.

Are Over-the-Counter Sleeping Pills Safer?

OTC options are often marketed as safer, but they carry their own risks. For example:

• Antihistamine-based pills (like diphenhydramine) can cause next-day drowsiness, confusion in older adults, dry mouth, and constipation.

• Herbal tablets (like valerian) are generally safer but lack strong evidence for effectiveness. Some users report vivid dreams, headaches, or gastrointestinal upset.

What Does the NHS Say About Sleeping Pills?

The NHS recommends lifestyle interventions and Cognitive Behavioural Therapy for Insomnia (CBT-I). This approach has been shown in multiple clinical trials to offer long-term sleep improvement without side effects.

Safer Alternatives to Sleeping Pills

If sleeping pills aren’t the answer long-term, what is? The following strategies are supported by the NHS and leading sleep specialists:

1. CBT-I (Cognitive Behavioural Therapy for Insomnia)

CBT-I is a structured, evidence-based approach that targets the thoughts and behaviours that disrupt sleep. A 2019 Cochrane review found CBT-I to be as effective as medication in the short term and superior in the long term.

2. Sleep Supplements

Some supplements offer sleep-promoting benefits without the drawbacks of pharmaceuticals. These include:

• Magnesium: Shown to improve sleep quality and reduce insomnia symptoms.

• Glycine: May reduce core body temperature and promote deeper sleep.

• Valerian Root: Mildly sedative effects, though results are mixed across studies.

  
  

3. Lifestyle Adjustments

Improving sleep hygiene often starts with simple, consistent habits. Limiting caffeine intake after 2pm can reduce stimulation later in the day. Avoiding screens before bed helps prevent blue light from interfering with melatonin production. Maintaining a regular sleep schedule supports a stable body clock. Creating a sleep-friendly environment with blackout curtains and white noise can further reduce disturbances and promote deeper, more consistent sleep.

Conclusion: Are Sleeping Pills Bad for You?

Sleeping pills are not inherently "bad"—but they are not a long-term solution. Used correctly and under medical supervision, they can provide temporary relief. However, their risks—from dependence to next-day impairment and long-term cognitive effects—are significant, especially with prolonged use.

For chronic sleep issues, the safest and most effective approach is to treat the root cause—whether through CBT-I, sleep hygiene, or targeted supplements.

Before turning to pills, consider speaking with a GP or consulting a sleep coach for sustainable alternatives.

Frequently Asked Questions About Sleeping Pills

Are sleeping pills safe to use in the UK?

Sleeping pills can be safe when used short term and exactly as prescribed by a GP. Most prescription options in the UK are intended for brief use only, typically one to two weeks. Longer use increases the risk of side effects, dependence, and reduced effectiveness.

How long should sleeping pills be taken for?

The NHS generally advises that prescription sleeping tablets should not be used for longer than one to two weeks. They are designed to provide short-term relief while underlying causes of sleep problems are addressed.

Can sleeping pills cause dependence?

Yes. Prescription sleeping pills, particularly benzodiazepines and Z-drugs such as zopiclone, can lead to both physical and psychological dependence. Over time, tolerance may develop, and stopping suddenly can result in withdrawal symptoms or rebound insomnia.

Do over-the-counter sleeping pills work?

Some over-the-counter options can help with mild, short-term sleep problems. Antihistamine-based products may promote drowsiness, while herbal remedies may support relaxation. However, evidence for long-term effectiveness is limited, and side effects such as next-day grogginess are still possible.

Are over-the-counter sleeping pills safer than prescription ones?

OTC sleep aids are generally considered lower risk, but they are not risk-free. Antihistamines can impair alertness and cause confusion in older adults, while herbal supplements vary widely in quality and effectiveness. They should still be used cautiously.

Why do sleeping pills cause next-day drowsiness?

Many sleeping pills remain active in the body into the following morning, particularly longer-acting medications like zopiclone. This can affect concentration, memory, reaction time, and driving ability the next day.

Can sleeping pills make sleep worse over time?

Yes. Regular use can disrupt natural sleep architecture and lead to rebound insomnia when the medication is stopped. This can create a cycle where sleep becomes increasingly difficult without medication.

Are sleeping pills suitable for older adults?

Extra caution is advised for older adults. Sedative medications are linked to a higher risk of falls, fractures, confusion, and memory problems in this age group. GPs often prioritise non-drug approaches for this reason.

What does the NHS recommend instead of sleeping pills?

The NHS recommends addressing sleep problems through behavioural and lifestyle approaches first. Cognitive Behavioural Therapy for Insomnia is considered the most effective long-term treatment, alongside good sleep hygiene and routine adjustments.

When should a GP be consulted about sleep problems?

A GP should be consulted if sleep problems persist for several weeks, affect daily functioning, or are accompanied by anxiety, low mood, or physical symptoms. This helps ensure that underlying causes are properly assessed and treated rather than masked with medication.
