Sleeping Tablets vs Melatonin: What’s the Difference?

When sleep becomes difficult, many people begin searching for something that will help them fall asleep faster and stay asleep for longer.

Two of the most common terms people encounter are sleeping tablets and melatonin.

They are sometimes discussed as though they are interchangeable, but they are actually very different.

Melatonin is a naturally occurring hormone that helps regulate the body’s sleep-wake cycle. Prescription sleeping medicines, on the other hand, act on specific systems in the brain to reduce wakefulness or produce a sedative effect.

There are also important differences in:

• how they work;

• who they are intended for;

• how quickly they act;

• how long they can be used;

• their potential side effects;

• dependence risk;

• and the types of insomnia they are designed to treat.

For people living with chronic insomnia, choosing the right treatment is particularly important. A newer prescription treatment such as QUVIVIQ▼ (daridorexant) works differently from traditional sleeping tablets and is specifically licensed for eligible adults whose insomnia has lasted at least three months and considerably affects daytime functioning.

In this guide, we compare sleeping tablets vs melatonin, explain where each treatment may fit and outline how 24 HR Pharmacy can help eligible adults access appropriate insomnia treatment through a clinically supervised online service.

What Is Melatonin?

Melatonin is a hormone naturally produced by the pineal gland in the brain.

Your body normally begins producing more melatonin as it becomes dark in the evening. Levels increase during the night and then fall again as daylight returns.

This process helps regulate your circadian rhythm, otherwise known as your internal body clock.

Synthetic melatonin can also be prescribed as a medicine.

Taking melatonin supplements the hormone naturally produced by your body and can help encourage sleep at the appropriate time. The NHS notes that it can help people fall asleep more quickly and may reduce waking during the night.

Is Melatonin a Sleeping Tablet?

Technically, melatonin is a medicine used for sleep problems, but it is not a traditional sedative sleeping tablet.

It does not work in the same way as medicines such as:

• zopiclone;

• zolpidem;

• benzodiazepines;

• or QUVIVIQ▼.

Instead of directly sedating the brain, melatonin primarily provides a signal that helps tell the body that it is time to sleep.

This makes it particularly relevant where the timing of sleep or the body clock is involved.

Is Melatonin Available Over the Counter in the UK?

No.

This is an important difference between the UK and countries such as the United States.

In the UK, melatonin is a prescription-only medicine. Melatonin supplements sold freely in some other countries are not authorised for general sale as food or health supplements in the UK.

The NHS specifically advises against ordering melatonin from unregulated online sources.

If melatonin is appropriate, it should be prescribed following assessment by a suitable healthcare professional.

Who Is Melatonin Commonly Prescribed For?

Melatonin prescribing depends on age, the type of sleep problem and the particular product being used.

For adults, melatonin is mainly used for short-term sleep problems in people aged 55 and over. Specialists may also prescribe it for longer-term sleep difficulties in certain adults and children.

Melatonin may also be prescribed in particular circumstances involving:

• jet lag;

• certain neurodevelopmental conditions;

• circadian-rhythm disorders;

• and other specialist-managed sleep problems.

It is therefore not a universal treatment for every adult with chronic insomnia.

What Is the Usual Melatonin Dose?

Melatonin dosing depends on why it has been prescribed and the formulation being used.

For short-term insomnia in adults, NHS guidance states that a common dose is:

2 mg modified-release melatonin once daily, taken around one to two hours before bedtime.

Treatment is generally short term and may be prescribed for up to 13 weeks in appropriate patients.

Other doses may be used for different indications, but patients should follow the exact dose and timing provided by their prescriber rather than copying another person’s treatment.

How Quickly Does Melatonin Work?

The NHS advises that melatonin usually takes around one to two hours to take effect.

It is therefore normally taken in advance of the intended bedtime rather than at the moment someone wants to fall asleep.

The timing can be especially important because melatonin works partly by influencing the body clock.

Can You Become Dependent on Melatonin?

Dependence is generally considered much less of a concern with melatonin than with traditional hypnotic medicines such as benzodiazepines or Z-drugs.

According to the NHS, people taking melatonin as prescribed are unlikely to become addicted to it.

However, that does not mean it should be taken indefinitely without review.

If you have been taking melatonin for a prolonged period, your doctor or pharmacist may want to assess:

• whether it is still helping;

• whether the underlying sleep problem has changed;

• whether you still need treatment;

• and whether the dose remains appropriate.

What Are Prescription Sleeping Tablets?

“Sleeping tablets” is a broad term covering several different types of prescription medicine.

Some of the main categories include:

Z-drugs

Examples include:

• zopiclone;

• zolpidem.

These work mainly by increasing the activity of GABA, a chemical messenger that reduces activity in the brain and produces sedation.

They are generally reserved for short-term severe insomnia because tolerance and dependence can develop.

Benzodiazepines

Certain benzodiazepines have also historically been used for insomnia.

They can be effective sedatives but are generally used cautiously because of risks including:

• dependence;

• tolerance;

• withdrawal;

• daytime impairment;

• falls;

• and memory problems.

Orexin receptor antagonists

A newer class of treatment includes medicines such as QUVIVIQ▼ (daridorexant).

These medicines work differently from traditional sedative treatments.

What Is QUVIVIQ▼?

QUVIVIQ▼ contains daridorexant and belongs to a class of medicines called dual orexin receptor antagonists.

Orexin is a natural chemical in the brain that promotes wakefulness.

By blocking orexin receptors at night, QUVIVIQ▼ reduces part of the brain’s wake-promoting signal.

It is designed to help people:

• fall asleep more easily;

• stay asleep for longer;

• reduce nighttime waking;

• and improve daytime functioning.

This mechanism is fundamentally different from melatonin.

Melatonin primarily reinforces the body’s normal “time for sleep” signal.

QUVIVIQ▼ directly reduces the biological signal responsible for maintaining wakefulness.

Who Is QUVIVIQ▼ Intended For?

QUVIVIQ▼ is licensed in the UK for adults with chronic insomnia where:

• symptoms have been present for at least three months;

• and poor sleep is having a considerable impact on daytime functioning.

Under current NICE recommendations, daridorexant is considered where cognitive behavioural therapy for insomnia (CBTi) has already been tried without adequate improvement, or where CBTi is unavailable or unsuitable.

This makes QUVIVIQ▼ particularly relevant to persistent chronic insomnia rather than occasional sleeplessness.

QUVIVIQ▼ Dosing

According to the treatment information used by 24 HR Pharmacy, QUVIVIQ▼ is available as:

• 25 mg tablets

• 50 mg tablets

The usual recommended adult dose is:

50 mg once nightly.

The tablet should be taken:

• once in the evening;

• within approximately 30 minutes before going to bed.

The maximum daily dose is 50 mg.

A lower 25 mg dose may be appropriate for certain patients, including some people:

• with moderate liver impairment;

• taking moderate CYP3A4 inhibitor medicines;

• taking other central nervous system depressants;

• or where the prescriber considers a lower dose clinically appropriate.

Melatonin vs QUVIVIQ▼: How Do They Differ?

The key difference is therefore not simply which medicine makes you sleepier.

They target different biological systems and are used for different clinical circumstances.

What About Zopiclone and Zolpidem?

Traditional prescription sleeping tablets such as zopiclone and zolpidem work differently from both melatonin and QUVIVIQ▼.

They act mainly on the brain’s GABA system, producing a sedative effect.

This can help people:

• fall asleep faster;

• reduce nighttime waking;

• and temporarily improve sleep.

However, they are usually prescribed only for short periods because:

• tolerance can develop;

• dependence is possible;

• withdrawal symptoms can occur;

• and stopping may temporarily worsen insomnia.

They therefore generally have a different role from QUVIVIQ▼ in chronic insomnia management.

Sleeping Tablets vs Melatonin: Which Works Faster?

This depends on the medicine.

Melatonin generally takes around one to two hours to work.

Some traditional hypnotics may begin producing sedation more quickly.

QUVIVIQ▼ is taken within approximately 30 minutes before bedtime, but its purpose is not simply to act as a rapid sedative. It works by reducing the brain’s wakefulness drive.

How quickly a treatment acts should not be the only consideration.

For chronic insomnia, the more important questions are:

• Why are you not sleeping?

• How long has the problem continued?

• How much is it affecting your daytime life?

• Has CBTi been tried?

• Which medicine is safest given your medical history?

Which Is Better for Chronic Insomnia?

There is no single answer for every patient.

For chronic insomnia lasting three months or longer, the first step should usually be identifying underlying causes and considering CBTi.

The NHS notes that CBT may help change the thoughts and behaviours that keep insomnia going.

Where CBTi has already been tried without sufficient improvement, or where it is unavailable or unsuitable, QUVIVIQ▼ may be considered for eligible adults.

Melatonin may be appropriate in certain patients and sleep disorders, but it is not automatically the preferred treatment for every adult with persistent chronic insomnia.

Which Is Better if Your Body Clock Is Out of Sync?

Melatonin may be particularly useful where sleep timing is part of the problem.

Because it acts as part of the body’s natural circadian system, it can be used in some circumstances involving:

• jet lag;

• delayed sleep timing;

• specialist-managed circadian disorders;

• and particular neurological or developmental conditions.

The exact timing of melatonin can be extremely important in these situations.

Taking it at an inappropriate time may fail to produce the intended benefit.

Which Is Better if You Wake Repeatedly During the Night?

Repeated waking can have many causes.

These include:

• chronic insomnia;

• obstructive sleep apnoea;

• menopause;

• chronic pain;

• reflux;

• alcohol;

• urinary symptoms;

• restless legs syndrome;

• and medication side effects.

QUVIVIQ▼ has been developed to help both sleep onset and sleep maintenance in chronic insomnia.

However, recurrent waking should first be assessed to make sure another condition is not responsible.

For example, sleeping medication is not a substitute for properly treating sleep apnoea.

What Are the Side Effects of Melatonin?

Possible side effects can include:

• headache;

• daytime tiredness;

• dizziness;

• nausea;

• irritability;

• and unusual dreams.

The NHS notes that some people may experience headaches or feel tired, sick or irritable the following day.

Some people should use melatonin cautiously, including those with certain:

• liver or kidney problems;

• autoimmune conditions;

• or medicine interactions.

Your prescriber should review your wider medical history before treatment.

What Are the Side Effects of QUVIVIQ▼?

Common side effects can include:

• headache;

• drowsiness;

• dizziness;

• nausea;

• and fatigue.

Uncommon effects can include:

• sleep paralysis;

• hallucinations;

• and vivid or unusual perceptions while falling asleep or waking.

Because QUVIVIQ▼ reduces wakefulness, patients also need to consider next-day alertness.

Can You Drive After Taking Melatonin or Sleeping Tablets?

Any sleep medicine that causes drowsiness can affect your ability to drive safely.

If melatonin makes you tired, dizzy or less alert the following day, you should not drive until those effects have passed.

For QUVIVIQ▼, patients should allow approximately nine hours between taking the medicine and driving or operating machinery, particularly during the first few days.

Even after this period, you should only drive when you feel fully alert.

Traditional sedative medicines such as zopiclone and zolpidem can also impair next-day alertness.

Never drive when you feel sleepy.

Alcohol and Sleep Medicines

Alcohol should not be used as a treatment for insomnia.

Although it may initially make you feel sleepy, it can fragment sleep and reduce sleep quality later in the night.

Alcohol can also increase the effects of prescription sleeping medicines.

For melatonin, the NHS advises avoiding alcohol because it can interfere with the way the medicine works.

For QUVIVIQ▼, alcohol should also be avoided because of the potential for increased sedation and impaired alertness.

Is Melatonin Safer Than Sleeping Tablets?

It is tempting to assume that because melatonin is a natural hormone it must automatically be safer.

That is too simplistic.

Melatonin generally has a different side-effect and dependence profile from traditional sedative hypnotics, but it is still a medicine.

It may:

• interact with other medicines;

• be unsuitable for certain medical conditions;

• cause daytime effects;

• or simply be the wrong treatment for the underlying cause of insomnia.

Likewise, prescription sleep medicines vary significantly in risk.

The safest treatment is the one selected after an appropriate clinical assessment.

Can You Take Melatonin and Sleeping Tablets Together?

Do not combine melatonin with another sleep medicine unless your prescriber has specifically instructed you to.

Combining sedating medicines can increase:

• drowsiness;

• dizziness;

• impaired concentration;

• poor coordination;

• and other side effects.

The NHS advises against taking other medicines or herbal remedies that make you sleepy while using melatonin unless this has been medically reviewed.

Always tell your prescriber about every medicine, supplement and sleep aid you are currently using.

Could Another Condition Be Causing Your Insomnia?

Before choosing melatonin or prescription sleeping medication, it is important to ask why you are struggling to sleep.

Potential causes include:

• anxiety;

• depression;

• menopause;

• chronic pain;

• thyroid problems;

• medication side effects;

• obstructive sleep apnoea;

• restless legs syndrome;

• alcohol;

• caffeine;

• shift work;

• and irregular sleep patterns.

Treating the underlying cause may improve sleep more effectively than adding another medicine.

Sleep Apnoea Should Not Be Mistaken for Insomnia

If you:

• snore loudly;

• stop breathing during sleep;

• wake choking or gasping;

• have morning headaches;

• or experience significant daytime sleepiness;

you may need assessment for obstructive sleep apnoea.

A general sleeping tablet is not an appropriate substitute for diagnosing and treating a breathing-related sleep disorder.

Where Does CBTi Fit In?

For chronic insomnia, cognitive behavioural therapy for insomnia remains an important treatment.

CBTi may include:

• sleep restriction;

• stimulus control;

• consistent waking times;

• challenging anxiety about sleep;

• reducing clock-watching;

• and improving behaviours surrounding bedtime.

Unlike medication, CBTi aims to change mechanisms that perpetuate insomnia over the long term.

Current NICE recommendations place QUVIVIQ▼ after CBTi has failed, or where CBTi is unavailable or unsuitable.

Sleeping Tablets vs Melatonin: Pros and Cons

Melatonin — Potential Advantages

• mimics a hormone naturally produced by the body;

• lower dependence concern than traditional hypnotics;

• useful for particular sleep-timing problems;

• available in several formulations;

• can help some patients fall asleep more easily.

Melatonin — Potential Disadvantages

• prescription-only in the UK;

• not appropriate for every form of chronic insomnia;

• effectiveness varies;

• timing is important;

• can cause next-day tiredness or other side effects;

• may interact with other medicines.

Prescription Sleeping Medicines — Potential Advantages

Depending on the specific medicine, they may:

• reduce the time taken to fall asleep;

• reduce nighttime waking;

• increase total sleep time;

• provide short-term relief from severe insomnia;

• or treat persistent chronic insomnia.

Prescription Sleeping Medicines — Potential Disadvantages

Depending on the medicine, potential concerns include:

• next-day drowsiness;

• falls;

• dizziness;

• impaired concentration;

• tolerance;

• dependence;

• withdrawal;

• medicine interactions;

• and the need for clinical monitoring.

QUVIVIQ▼ has a different mechanism from older Z-drugs and benzodiazepines, but still requires careful prescribing and regular review.

How 24 HR Pharmacy Can Help

At 24 HR Pharmacy, the aim is not simply to provide a sleeping tablet to everyone who reports poor sleep.

The insomnia service is designed to assess whether your symptoms are consistent with chronic insomnia and whether prescription treatment is clinically appropriate.

1. Complete an Online Insomnia Assessment

Your confidential consultation can cover:

• how long your sleep problem has lasted;

• how frequently symptoms occur;

• whether you struggle to fall asleep or stay asleep;

• how sleep affects your daytime functioning;

• whether CBTi has already been tried;

• current medicines;

• medical conditions;

• mental health;

• alcohol and substance use;

• and symptoms suggesting another sleep disorder.

2. Review by a UK-Registered Prescriber

A qualified prescriber reviews the information and determines whether prescription treatment is appropriate.

This includes screening for:

• medicine interactions;

• contraindications;

• narcolepsy;

• possible sleep apnoea;

• psychiatric concerns;

• liver problems;

• and other factors that could affect treatment safety.

3. QUVIVIQ▼ Where Clinically Appropriate

For eligible adults with chronic insomnia, QUVIVIQ▼ may be considered.

The usual dose is:

50 mg once nightly within approximately 30 minutes before going to bed.

A lower 25 mg dose may be appropriate for selected patients depending on clinical circumstances.

Treatment is only prescribed where the prescriber considers it safe and suitable.

4. Regulated Dispensing and Discreet Delivery

Where treatment is approved, the prescription can be dispensed through 24 HR Pharmacy and supplied with the appropriate patient information.

Treatment can then be delivered discreetly to your chosen UK address.

5. Ongoing Review

Insomnia medication should not simply be prescribed indefinitely without reassessment.

For QUVIVIQ▼, suitability should be reviewed within three months of starting treatment and periodically thereafter.

Reviews can assess:

• whether sleep has improved;

• whether daytime functioning has improved;

• whether side effects are occurring;

• whether other medicines have changed;

• and whether treatment remains appropriate.

Frequently Asked Questions

Is melatonin stronger than sleeping tablets?

“Stronger” is not a useful comparison because the medicines work differently.

Melatonin helps regulate the body's sleep-wake signal, while other insomnia treatments may directly reduce wakefulness or increase sedation.

Is melatonin available without a prescription in the UK?

No. Melatonin is a prescription-only medicine in the UK.

What is the usual melatonin dose for insomnia?

For short-term insomnia in appropriate adults, a commonly used dose is 2 mg modified-release melatonin taken one to two hours before bedtime. Your actual dose should follow your prescription.

What is the usual QUVIVIQ▼ dose?

The usual recommended dose is 50 mg once nightly, taken within approximately 30 minutes before bed.

Some patients may require 25 mg depending on their medical history or interacting medicines.

Is melatonin addictive?

Melatonin is unlikely to cause addiction when taken as prescribed, according to NHS guidance.

Is QUVIVIQ▼ the same as melatonin?

No.

Melatonin supplements the body's natural sleep hormone.

QUVIVIQ▼ contains daridorexant and works by blocking orexin receptors involved in maintaining wakefulness.

Which is better for long-term insomnia?

It depends on the individual and the cause of insomnia.

For chronic insomnia, CBTi is an important first-line treatment. QUVIVIQ▼ may be considered for eligible adults when CBTi has not worked or is unavailable or unsuitable.

Melatonin has different licensed and specialist uses and is not automatically the preferred treatment for chronic insomnia in every adult.

Can I take melatonin with QUVIVIQ▼?

Only if specifically advised by your prescriber.

Do not combine sleep medicines independently because sedating effects and interactions may increase.

Can I buy melatonin online?

In the UK, melatonin is prescription-only. The NHS advises against purchasing unregulated melatonin products online.

Can I access prescription insomnia treatment online?

Yes, but legitimate online treatment requires an appropriate clinical consultation.

Through 24 HR Pharmacy, eligible adults can complete an online assessment that is reviewed by a qualified prescriber before prescription treatment is approved.

Final Thoughts

Melatonin and prescription sleeping tablets may both be used to support sleep, but they are not the same thing.

Melatonin is a naturally occurring hormone that helps regulate the body's sleep-wake cycle. Prescription melatonin can be useful for selected short-term sleep problems, circadian disruption and certain specialist indications.

Traditional sleeping tablets, such as Z-drugs, primarily produce sedation and are usually intended for short-term severe insomnia because tolerance and dependence can develop.

For adults with chronic insomnia lasting at least three months, QUVIVIQ▼ (daridorexant) offers a different approach. Rather than working through the GABA system or supplementing melatonin, it blocks the orexin pathway responsible for promoting wakefulness.

The usual QUVIVIQ▼ dose is 50 mg once nightly, with 25 mg used in selected circumstances. Treatment requires a clinical assessment and ongoing review.

The right option depends on the cause and duration of your insomnia, your medical history, other medicines and the treatments you have already tried.

Through its online insomnia service, 24 HR Pharmacy can help eligible adults receive an appropriate clinical assessment, prescriber review and access to prescription treatment where it is safe and suitable.
