Circadin (melatonin) 2mg tablets ease symptoms of jet lag in people travelling over three or more time zones. To learn more about jet lag, visit our Online Doctor jet Lag page. Circadin 2mg tables are available from The Independent Pharmacy Online Doctor service, following a free consultation.
Circadin 2mg tablets contain the active ingredient melatonin, a hormone that the body releases when it is dark, letting your body know it is time for sleep. Melatonin helps to regulate the body’s clock (circadian rhythm) and acts on chemical receptors in the brain to promote sleep. Melatonin in Circadin 2mg tablets will help alter your normal circadian rhythm, allowing you to sleep when it is dark in your new time zone and ease the symptoms of jet lag.
Melatonin is prescribed to treat insomnia in patients over the age of 55, however it can also be prescribed 'off-label' for short-term use in patients who are travelling across numerous times zones to treat jet lag.
Click here to read studies on the effectiveness of Circadin in treating Jet Lag 'off label'. 'Off label' means that the medicine is being used to treat a condition other than those that it was initially licensed to treat. For example, Circadin has been licensed to treat insomnia but can also be used 'off-label' to relieve jet lag. This means that there is less established data regarding the effectiveness of this treatment for the condition which it is prescribed and means that the instructions contained in the product information leaflet will not match the condition you are treating. You should always follow the instructions on the dispensing label on your medicine and contact us if you have any questions.
Take Circadin at bedtime in your new time zone on the day of arrival. Continue taking it for 2 – 5 nights depending on your response to the medication and the persistence of jet lag. You will not develop sudden drowsiness with melatonin; it will produce a more natural sleepiness 1 -2 hours after you take it.
Jet lag usually only occurs if you travel across three or more time zones, otherwise you should not need to take melatonin. Jet lag can be particularly bad when travelling east. Plan for melatonin treatment on your return home in addition to arrival at your destination. 3 nights’ treatment upon arrival and return home is should be enough to help you adjust to your new time zones.
Unlike some other ‘sleep’ medications, Circadin does not result in tiredness or grogginess in the morning. This is because it does not depress your central nervous system like other hypnotic drugs and sleeping tablets. For this reason, it is not advisable to use traditional sleeping medicines to treat jet lag.
Do not chew or crush Circadin tablets. They need to be swallowed whole to activate their prolonged release formulations. This ensures that they release melatonin slowly throughout the night, mimicking the body’s natural sleep pattern.
Circadin prolonged-release melatonin 2mg, is an innovative sleep medication, first in a new class of drugs: melatonin receptor agonists. Circadin® is available by prescription only, and is approved for primary insomnia treatment worldwide.
Melatonin is a hormone produced by the body at night. It acts as a signal to the internal biological clock in our brain, allowing the adjustment of functions such as sleep, blood pressure and certain hormones during sleep. Melatonin production is inhibited by light and diminishes with age and in some medical conditions.
