If you’re finding it hard to get to sleep or stay asleep on a regular basis, you might have insomnia.
Insomnia is common, yet it is an underdiagnosed condition worldwide, with estimates that over 16% of the global population has it. We offer 2 different medications, including Quiviviq (25mg or 50mg) and Melatonin PR.
Melatonin is a very short-term course of treatment – it is usually prescribed for 1 to 4 weeks for insomnia and, in some cases, 13 weeks if approved by a doctor.
Quiviviq has a longer treatment period of at least 3 months but up to 1 year if your doctor thinks this is suitable. It is a second-line treatment to Cognitive Behavioural Therapy for Insomnia (CBT-I). It is intended for use when CBT-I has not been effective.
You can check your suitability and request treatment for insomnia at ZAVA through a short consultation, which will be reviewed by our GMC-registered UK doctors. If approved, your treatment will be delivered straight to your home.

About insomnia treatment
-

Insomnia is a sleep disorder that can prevent you from falling or staying asleep. As a result, it can stop you from getting the sleep you need that is restorative for your body. Types of insomnia include short-term (acute) and long-term (chronic).
Short-term insomnia
Otherwise known as acute insomnia, short-term insomnia is common and usually temporary. It typically lasts from a few days up to no more than 3 months. Causes of short-term insomnia include:
- life changes – such as bereavement or trauma
- emotional stress – like anxiety or depression
- jet lag
- substances, food or drink – alcohol, caffeine, or eating too late
- physical illness – pain, illness, or medications
- bad sleep habits – napping too much, irregular sleep schedules (due to shift work, for example), or too much stimulation before bed
Acute insomnia usually goes away once one of the underlying issues listed has settled or been addressed. If it does not go away and lasts longer than 3 months, you may have chronic insomnia.
Long-term insomnia
Also known as chronic insomnia, long-term insomnia is when you have sleeping difficulties that last longer than 3 months. The treatment for this kind of insomnia is more complex because the causes of it vary from person to person. It can affect your mood, ability to concentrate, and your energy levels.
NICE (National Institute for Health and Care Excellence) outlines that chronic insomnia often happens alongside other medical conditions, such as:
- anxiety
- depression
- chronic obstructive pulmonary disease (COPD)
- cardiovascular disease
- neurological conditions
- diabetes
- musculoskeletal conditions
- chronic pain
Trauma and post traumatic stress disorder (PTSD) can also cause chronic insomnia, with insomnia being a core, persistent PTSD symptom – with 90% of patients experiencing insomnia of some kind.
Women in the UK are 1.5 to 2 times more likely to have chronic insomnia than men, often related to menopause and changes in hormones.
Chronic insomnia can go away, but you may need treatment. You may require medication, psychotherapy, or Talking Therapies, or either of the 3.

Available treatments for insomnia at ZAVA include:
- Quiviviq
- melatonin
Quiviviq
Quiviviq is a prescription-only oral tablet taken daily, 30 minutes before you go to sleep. It contains the active ingredient daridorexant, which works to:
- regulate your body clock (sleep-wake cycle)
- reduce night-time alertness
It is usually taken for up to 3 months at first. If your doctor thinks it is suitable, they may recommend you take it for longer, for up to another 9 months. You cannot take Quiviviq for more than 1 year, as safety and effectiveness have not been studied beyond this point.
In clinical trials, within 3 months patients saw a significant improvement in how:
- alert they are in the daytime
- long it took to fall asleep
- long they stayed asleep
At ZAVA, Quiviviq is available in 25mg and 50mg doses.
Melatonin (prolonged release)
Melatonin PR (prolonged release) is a prescription-only oral tablet taken as 1 tablet daily for up to 13 weeks, 1 to 2 hours before you go to sleep.
It contains a synthetic form of melatonin, mimicking a natural hormone that is produced by the pineal gland in the brain that usually regulates your sleep cycle, or ‘body clock’. It is typically prescribed for a maximum of 13 weeks in adults (around 3 months).
According to new studies, melatonin is highly effective at improving sleep quality as well as restoring the biological clock. Melatonin is also an effective treatment for jet lag.
At ZAVA, Melatonin PR for insomnia is available in 2mg tablets.
Over-the-counter medication
There are many over-the-counter sleeping medications available, some are made from natural, herbal ingredients.
A lot of these work as great short-term treatments for acute insomnia, or if you are allergic to ingredients in prescription-only treatments. You should always check with your pharmacist or doctor if over-the-counter sleep medication is suitable for you before taking it. Some of these treatments may cause morning drowsiness and can only be taken for 1 to 2 weeks, so if your symptoms persist, you may need a prescription for insomnia.
Here are a few examples of over-the-counter UK sleeping medications and how they work:
Nytol
Nytol contains diphenhydramine, which is a popular sedative antihistamine. It works by blocking histamine receptors in the brain, which makes you drowsy, less alert, and tired. It usually takes effect within 20 to 30 minutes. It should generally be taken for up to 2 weeks.
Kalms Night
Kalms Night contains natural ingredients, a dry extract of Valerian Root. It is commonly used for temporary relief of sleep disturbances by causing drowsiness, helping you to fall asleep. They are typically taken 30 to 60 minutes before you are due to go to sleep. Patients find they are most effective 2 weeks after starting to take them regularly.
Phenergan Night Time
Phenergan Night Time contains promethazine hydrochloride. This is an antihistamine that causes drowsiness to help with short-term sleeplessness. It is a strong over-the-counter medication. You can use it for no longer than 10 days. They are taken 30 to 60 minutes before bed. They last 12 hours, so may cause drowsiness when you wake up.
Sominex
Sominex contains promethazine hydrochloride, like Phenergan Night Time. So, it is a sedating antihistamine which makes you drowsy so you can fall asleep easier. It contains 20mg, whereas Phenergan contains 25mg. You may find this a suitable alternative if you find Phenergan too strong. You can also take Sominex 20 minutes before you go to sleep. You should not take Sominex for longer than 7 days.
We do not offer over-the-counter sleeping aids at ZAVA. If you have tried these medications and still are having trouble falling asleep, you can start an online consultation for Quiviviq or Melatonin (PR).

Clinical studies have found that insomnia medications are effective in the short-term for sleepless nights, however in the long-term, Talking Therapies or psychotherapy may be required.
At ZAVA, you can request melatonin, which can enhance sleep quality in the short term. Or Quiviviq, which has been clinically recognised to help 53% of people get better sleep. However, you cannot take either medication long-term. For example, the maximum duration recommended is 12 months for Quiviviq, and around 3 months (13 weeks) for melatonin, if this is approved by your doctor.
The National Institute of Care and Excellence (NICE) recommends that in the long-term, insomnia should be treated (first-line) with Cognitive Behavioural Therapy for Insomnia (CBT-i). This is a structured, session-based talking therapy treatment recognised as a first-line non-drug treatment for the sleep disorder. This may work for you if your insomnia may be caused by prolonged stress, grief, anxiety, phobias, depression, PTSD, or other psychological disorders.
Insomnia is a complex condition. You may find that insomnia medications like Quiviviq (daridorexant) may be suitable if CBT-i is not available or is unsuitable for you. You may find this treatment line more suitable if you have physical condition-related insomnia, which is chronic or musculoskeletal.
You may even find that using insomnia medication works for you in the short-term, while maintaining CBT-i works for you in the long-term. Other options are available for insomnia, and you may need a referral from your GP to a sleep clinic or neurology specialist.
What is the best medication for insomnia?
The best treatment for insomnia varies from person to person. At ZAVA, we offer melatonin and Quiviviq (daridorexant).
Melatonin is a short-term insomnia medication, which you should only take for up to 13 weeks. Whereas, you can take Quiviviq for up to 12 months if your doctor finds it suitable.
Quiviviq contains daridorexant, which is a part of a class of drugs referred to as dual orexin receptor agonists (DORA). These work to improve sleep-wake cycles by turning off wakefulness in your brain by blocking the chemical called orexin that keeps you alert. Quiviviq is the first dual orexin receptor agonist medication to be authorised for treatment of insomnia in the UK.
To help you consider which treatment may be suitable for you to request, here is an overview of alternative DORA treatments to Quiviviq which is offered by ZAVA and how they compare:

You can treat insomnia without medication in a range of ways that involve physical activity and psychotherapy or Talking Therapies. For example, try:
Cognitive Behavioural Therapy
Otherwise known as CBT. There is a short programme specified for insomnia that lasts 6 to 8 weeks, known as CBT-I. This is usually the first treatment recommended for insomnia and the NHS will refer you for this before prescribing medications, unless there is a reason it’s not suitable for you. CBT-I can help with:
- adjusting thought patterns around sleep
- challenging anxiety around sleep
- finding calming techniques like deep breathing or progressive muscle relaxation
- retraining the brain and its associations to sleep
CBT-I can be helpful because insomnia is a complex condition and varies from person to person.
Sleep hygiene
Changing your sleeping habits can positively impact your sleep pattern and potentially help your insomnia. For example, you may find it helpful to go to bed at a set time and wake up at a set time.
Consider your environment when you sleep, too. If you are affected by light or noise, try:
- using blackout curtains, or eye masks
- ear plugs, white noise, or heavy curtains to shut out noise
- avoiding screens (phones and TV) before bed
Take time to get comfortable and develop a bedtime routine.
Mindfulness and meditation
Increasing evidence backed by data has shown that mindfulness meditation can be a great form of therapy for insomnia.
There are a range of online resources on mindfulness and meditation which can help to add to your bedtime routine, which may help you relax so that you can go to sleep.
You can try:
- breathing techniques
- guided meditation videos or podcasts
- progressive muscle relaxation
Exercise
Several studies on different types of exercise on insomnia patients have found that it is beneficial in the treatment of insomnia. One study found that jogging, yoga, and Tai Chi in particular helped patients to get to sleep faster, and stay asleep. These low-impact exercises can also be done gently and can help with physical or chronic pain which can cause insomnia too.
You can access these exercises by simply going for a walk around the block, or finding resources through videos online which are accessible for free on yoga or Tai Chi moves. You could wind down with light yoga before bedtime as a way to relax your muscles, for example.
Regular physical activity can lead to improved sleep quality overall, helping your sleep health and overall health.
If you can, try adding exercise, whether this is light, aerobic, or more cardio-based, to see if it makes a difference to your sleep schedule.
Natural sleep aids
Try natural sleep aids before bed time like:
- herbal teas
- warm milk, or hot chocolate, or warm malted milk drinks
- valerian root based herbal teas
Getting yourself ‘cosy’ before bedtime may make it easier for you to go to sleep.
Acupuncture
Acupuncture has been clinically proven to be a safe, effective and evidence-based treatment for insomnia with minimal side effects. It can help with sleep quality through relaxation, as well as reducing anxiety.
You can get acupuncture therapy at acupuncture clinics. It is also available via some local GP clinics through physiotherapists on the NHS.

Can you cure insomnia?
Yes. In most cases, insomnia can be treated. It is a complex condition and ways of treating it vary from person to person. For example, short-term (acute) insomnia treatments are different from long-term (chronic) insomnia. Note that there is no ‘quick-fix’ fast way to cure insomnia, a variation of medication-based treatment in the short-term and therapeutic treatments for the long-term can help you treat insomnia.
Can sertraline cause insomnia?
Yes. Insomnia is a very common side effect of sertraline. Although not everyone experiences side effects of sertraline. However, insomnia can also be caused by depression which is treated with sertraline. If you are unsure whether your insomnia may be caused by other conditions like depression or your medication, you should speak to your doctor.
Can vaping cause insomnia?
Yes, especially if your vape contains nicotine. Clinical studies have found that e-cigarettes (vapes) may be linked to disturbances of sleep. Nicotine is a stimulant which can reduce the quality of your sleep and increase how many times you wake up at night.
Will insomnia eventually go away?
Yes, it can. Insomnia is a complex condition but it can be treated and can eventually go away.
Short-term (acute) insomnia usually goes away on its own. Acute insomnia is often caused by emotional stress, anxiety, or things like shift work and jet lag, life changes or illness. Once these things go away, insomnia can too. Acute insomnia typically lasts from a few weeks up to 3 months.
Long-term (chronic) insomnia can also go away, however it takes longer treatment and needs specific strategies, sometimes involving Talking Therapy or CBT-I in addition to medication.
If you have been struggling sleeping for longer than 3 months, it is likely that you may have chronic insomnia. You should speak with your doctor and they may suggest a suitable treatment for you.
