Buy Circadin (Melatonin) Online

Circadin is a treatment for secondary insomnia in adults. Circadin contains a naturally occurring hormone called melatonin.

You can buy melatonin online from Prescription Doctor following a short medical questionnaire. If our doctor approves your request, your item will be dispensed and dispatched from our UK based pharmacy via a discreet next-day delivery service.

What is melatonin?

Melatonin is a hormone which influences your sleepiness and wakefulness. It is produced by a small pea-shaped gland in the centre of the brain called the pineal gland. While the functions of the pineal gland is not yet fully understand, it does play a key role in regulating the body's natural clock, also known as the circadian rhythm.

Over the course of the day, the pineal gland secretes melatonin. The secretion of melatonin can be influenced by environmental factors such as how light or dark it is.

Light disrupts the production of melatonin which can impact your sleeping patterns. If not enough melatonin is present when you are ready to go to bed, you may struggle to naturally fall asleep. This difficulty sleeping is known as insomnia.

What is melatonin used for?

Melatonin is used primarily as a short-term treatment for insomnia in adults over the age of 55. Your doctor will tell you how long you should take melatonin for. They may tell you to only take melatonin only 2 or 3 times a week.

Melatonin is sometimes prescribed off-label to treat jet lag, which occurs when travelling across time-zones.

If you are suffering from insomnia, it's important to speak to your doctor to determine the probable cause of your condition before buying melatonin online. Your doctor will be able to discuss your condition with you and provide you with more information.


How does melatonin work?

Melatonin is a key hormone which promotes and regulates sleepiness. The more melatonin that is produced, the sleepier you become.

During the day, when there is natural light, the level of melatonin in the body is low.

During periods of diminished light exposure, such as evenings and during the night, the hypothalamus in the brain triggers the release of the melatonin.

Throughout the day, the amount of melatonin in the body gradually increases, reaching its peak at around midnight.

If there is not enough melatonin in the body near bedtime, the body doesn't feel tired and so it can be difficult to fall to sleep. By introducing a synthesized melatonin near bedtime, the body can fall naturally into a deep and restful sleep.

How does melatonin compare to other sleeping aids?

Synthesized melatonin, found in Circadin 2mg, mimics the natural melatonin produced by the body. As a result, melatonin is well tolerated and unlikely to cause withdrawal symptoms, dependence, cognitive impairment or daytime sedation.

The mechanism of melatonin is more nuanced than the mechanism of other sleep aids such as Z-drugs. Unlike non-benzodiazepines, such as Zopiclone, melatonin does not cause immediate drowsiness, nor does it pose a risk of a come-down once the hormone is metabolised. Instead, melatonin induces a gradual and natural progression to sleep.


How do I take melatonin?

Melatonin is available in a slow-release tablet called Circadin. Each Circadin tablet contains 2mg of melatonin.

Swallow one slow-release tablet whole after food with a glass of water. Circadin should be taken 1 or 2 hours before you intend to go to bed in order to work effectively.

Do not take melatonin during the day. Taking melatonin at the wrong time could shift your circadian rhythm undesirably, reducing the amount of sleep you get at night or causing unwanted drowsiness during the day.

For optimal results, aim to go to bed at the same time each night and take melatonin up to 2 hours before you go to sleep.

Circadin 2mg is typically prescribed for 21 days in adults with insomnia. After completing treatment with melatonin, you should arrange an appointment with your doctor to review how effective the treatment has been for you.

Do not consume alcohol while taking melatonin as this can reduce the effectiveness of the medicine or cause undesired effects, such as excessive drowsiness or restless sleep.

Other sleep aids, such as benzodiazepines, can worsen the effects of melatonin or render the medicine ineffective.

If you are unsure how to take Circadin, speak to your doctor or a pharmacist for advice.


Melatonin side effects and cautions

Melatonin is relatively safe and well tolerated. Clinical trials show that melatonin has a low incidence of adverse effects. There is no evidence which states that it causes dependence, nor that the treatments causes daytime sleepiness as seen in other hypnotic medication.

Due to its ability to initiate a deep and restful sleep pattern, melatonin can indirectly improve daytime functioning.

Important: Melatonin must not be taken with other sleep medication such as:

  • Benzodiazepines
  • Zaleplon
  • Zolpidem
  • Zopiclone

When you buy melatonin online from Prescription Doctor, you will need to fill out a medical questionnaire in order for our doctor to prescribe melatonin safely.

It is important that you inform our doctor of any other medication you are currently taking including health supplements, regardless of whether they were prescribed by your doctor or bought over-the-counter at a pharmacy.

Frequently asked questions

What should I do if I forget to take melatonin when I should?

If you forget to take melatonin when you should, take it as soon as you remember. If it is nearly time for your next dose, skip the missed dose and take your next dose at the usual time.

Do not take more melatonin to make up for the dose you missed.

What should I do if accidentally take more melatonin than I should?

If you accidentally take more melatonin than you should, you may feel very sleepy.

There is little evidence to suggest that taking too much melatonin can cause significant harm, however, it is imperative that you inform your doctor if you accidentally take more than the prescribed dosage.

Why is melatonin only recommended for people over the age of 55?

Melatonin production in people over the age of 55 in typically slower. To combat this natural drop in melatonin, Circadin can release a synthetic replacement gradually in patients to gradually and naturally induce sleep.

While Circadin can be prescribed to people under the age of 55, if is more common for people under the age of 55 to suffer from primary insomnia. Unlike secondary insomnia, which Circadin is used to treat, primary insomnia is linked to diet and environment and can often be treated by making appropriate lifestyle adjustments.

How long does it take for melatonin to leave the body?

Melatonin is metabolised very quickly and can be expected to leave the body within 12 hours after administration.

While it may not be safe to drive or operate machinery after taking Circadin, melatonin is not a controlled substance and will not affect drug or breathalyser tests.

Will melatonin make me drowsy?

Melatonin is not a sedative and will not cause you fall asleep immediately after taking it.

Within 2 hours of taking Circadin, your body will prepare itself for a natural sleep.

If taken correctly, you should awake feeling refreshed and well rested. IF you feel tired during the day after taking melatonin, speak to your doctor.

Will melatonin affect my ability to drive or operate machinery?

It is advised not to drive or operate machinery for up to 8 hours after taking melatonin. If you feel sleepy in the morning after taking melatonin, it is strongly advised not to drive, ride a bike, operate machinery or perform any activity which may put you in danger if you are not fully alert.
