Order Jet Lag Treatment Online

What is Jet Lag?

The earth is divided into 24 time zones: time changes by one hour for every 150 degrees of travel east or west of the Greenwich meridian. Our bodies are programmed to be active and alert during the day and to sleep at night. Travelling across the earth's time zones disrupts these natural rhythms, resulting in extreme tiredness referred to as jet lag.

Jet lag can take several days to overcome, therefore our service can help you plan ahead to minimise jet lag. This treatment service is for patients who will be flying to another country where the time difference is more than three hours.

All services provided by Anytime Doctor are safe, fast and confidential. You can obtain treatment within the privacy of your home and without the inconvenience of waiting for an appointment.

Medicines at a glance


Circadin is a tablet form of the hormone melatonin. Melatonin is secreted naturally by the pineal gland in your brain as your eyes register the fall of darkness. At night, melatonin is produced to help our bodies regulate our sleep-wake cycles. By taking this hormone in a tablet form it can help your body adapt to your new destination's local time quicker.

Side Effects
  • nausea
  • diarrhoea
  • headaches
  • stomach discomfort
Please Note

All medication can cause side effects. Details of all side effects, including rare side effects to be aware of, are listed in the patient information leaflet (PIL). When completing your medical questionnaire it is very important that you answer the questions truthfully. This is to ensure your doctor has a full picture of your medical history before prescribing. List all medicines you are already taking, including non-prescription and herbal medicines.

Patient Information Leaflet

Circadin PIL


You should only take this treatment if you have travelled to another country that has three or more hours time difference from the country that you left.

Not suitable if you are allergic to melatonin, or if you do not intend on travelling to a country where the time difference is more than three hours. Do not use if you take regular medicine to help you sleep. This service is not suitable for women who are pregnant or breast feeding, or people with severe allergies or auto-immune diseases.


Your body will naturally overcome jet lag. Melatonin is used to accelerate this process.

Symptoms of jet lag include:

  • extreme tiredness
  • insomnia
  • stomach upsets
  • aches and pains
  • disorientation

Currently within the UK, Circadin (melatonin) is not licensed for the treatment of jet lag. However, clinical evidence shows that melatonin can help with the symptoms of jet lag and it is therefore widely used. Melatonin is a hormone that is produced by a small gland under your brain. It's released in the evening and tells your brain it's time to sleep - this is part of your body clock.

There have been a number of studies to see if taking melatonin supplements can prevent jet lag, but results have been mixed. Available evidence points to a greater benefit the larger the time difference between the two countries visited.

When you arrive at your destination, going for a nap is the worst thing you can do, because it sets your body's rhythms back to home time. Staying active on arrival will help the body adjust to the new time zone. As eating and sleeping are your body's time indicators, it is also important to fit in with what the locals are doing when you arrive. Exposing yourself to as much daylight as possible might also be a good idea, because it has been shown that bright light can help to reset circadian rhythms.
