Jet lag affects millions of travellers every year. The condition occurs when taking a long-distance flight crossing several time zones. Melatonin tablets help you sleep at night and allow you to adjust to the local time more quickly, reducing the symptoms that can otherwise spoil your holiday.

Get ready for you next holiday and order jet lag tablets from DrEd. The tablets are a prescription only medication. You need to fill in a brief questionnaire to place your order, so our doctor can approve appropriate treatment. Once your prescription has been approved we will dispatch your medication via post.

Prescription and delivery are included.

Melatonin is currently not licensed for use in jet lag in the UK. It is licensed for use to treat insomnia, but a large scientific review has approved its use for prevention of jet lag.

What is jet lag?

Jet lag occurs when you take a long-distance flight which crosses several time zones. Most travellers find that jet lag becomes noticeable when crossing at least four time zones. Jet lag describes a condition which happens when your body has to adjust to a different time zone.

Your body has a so-called “body clock” which is regulated by the change between day and night, which triggers the release of hormones in your body. When it gets dark, the brain produces a hormone called melatonin, which helps prepare your body for sleep and rest, and helps regulate your internal body clock. During daytime, the production of this hormone is prevented. Melatonin serves the function of telling your body when to go to sleep. It is responsible for making you feel tired and sleepy in the evening and also helps your body to rest.

When you travel to a different time zone, your body needs to get used to night time occurring at a different point in time than you are used to. This means, that your body needs to inhibit and increase the production of melatonin at a different time than usual. Most people find it slightly easier to adjust to a new time zone when flying west. When you travel west, you need to stay up longer when you arrive at your destination.

When travelling east however, it gets dark earlier at your destination. This means that you need to sleep earlier than you normally would, in order to get used to the new routine. Often, travellers find that it takes them longer to get over their jet lag when travelling east. In addition to poor sleep, travellers often feel groggy during the day, and may feel weak, disorientated, lethargic, nauseous and restless, until their body has adapted to the new time zone.

What are Jet lag tablets?

You may not be able to avoid jet lag entirely but there are a number of ways to minimise the symptoms and help you adjust to the local time. Melatonin tablets can significantly reduce the time it takes you to settle into the new routine. They contain the hormone melatonin, which is the same hormone that your body naturally produces to regulate your sleep-wake-cycle. Taking one tablet every night for the first few days at your travel destination will help you sleep at the right time and feel well during the day, until you have adapted to the new clock. The tablets compensate for your body failing to produce melatonin when it is night time in the new time zone. You will find it easier to fall asleep and get up when it is morning, which is vital to help you adjust to the local time.

Melatonin is currently not licensed for use in jet lag in the UK. It is licensed for use to treat insomnia, but a large scientific review has approved its use for prevention of jet lag.

How can I beat jet lag?

In addition to taking melatonin tablets you can try to settle into the new routine while you are still on the plane. Try to sleep when it is nighttime at your travel destination - this will help you stay up when you arrive. Likewise, delay going to sleep until you arrive, if you are going to arrive in the evening. The faster you manage to adjust to the time at your destination, the milder your symptoms of jet lag are going to be.

It helps if you begin your journey well-rested. If you begin your journey tired, you are more likely to encounter symptoms. It is also important that you drink plenty of water - dehydration exacerbates some jet lag symptoms such as confusion and lack of concentration. Although drinking plenty of fluids will help you feel better, drinking alcohol will not. Alcohol has a negative impact on the quality of your sleep and should be avoided (or enjoyed in small quantities). You may find it helpful to drink caffeine when you need to stay up longer or when getting up early. However, you should make sure that you do not consume any caffeine within the hours before you are planning to sleep.

Symptoms of Jet Lag

The symptoms of jet lag vary between travellers. They also vary depending on the distance you are travelling - the further you travel and the more time zones you cross, the more pronounced your jet lag will be.

The primary symptom of jet lag is a disturbed sleep cycle. Due to the different cycle of night and daytime, you may find it difficult to sleep when it is night and stay awake during the day. As a result, you may feel tired and you may find it difficult to concentrate. Your disturbed sleep cycle has an impact on your body and can cause additional symptoms such as:

  • nausea, indigestion, diarrhoea and constipation
  • changes in appetite
  • confusion and light-headedness
  • feeling irritable
  • feelings of disorientation and clumsiness
  • memory problems
  • excessive sweating
  • headaches
  • sore muscles
  • feeling tired and unwell
  • irregular periods (may affect women who travel on a regular basis)

Depending on how far you have travelled and how well you are adjusting, your jet lag symptoms may persist for several days. In most cases, they subside within two days.
