Short facts about Melatonin
How to take

Take either the 2mg prolonged-release, or the 3mg immediate-release tablets just before sleeping when arriving in a new time zone.

How it works

Melatonin helps you to adjust to the change in light stimulus across different time zones.


This treatment can be taken upon arrival and can help with sleeping difficulties.


Melatonin is available in 2 mg prolonged-release tablets and 3mg immediate-release tablets.

Side effects

Side effects are not very common, but may include nausea, headaches and irritability.

How does it work?

Melatonin is a naturally occurring hormone that is produced by the pineal gland. It helps regulate sleep alongside natural light stimuli. When individuals suffer from jet lag, it's because the levels of melatonin have been unable to adjust to the change in light stimulus after arriving in a new time zone. As a result, sufferers of jet lag find sleeping difficult or are tired during the day until their bodies adjust.

By synthetically increasing the amount of melatonin in the body, the symptoms of jet lag can be alleviated.

Who can use Melatonin?

Generally, everyone over the age of 18 should be able to use this treatment safely. However, you should always consult with your doctor first before using any medication, as they will be able to advise of any interactions that may occur due to underlying conditions.

How do you take it?

Melatonin should only ever be taken as prescribed by a doctor, but for the purposes of jet lag treatment individuals should take one (increasing to a maximum of two) 3mg immediate-release tablet before sleeping when in a new time zone. This is to be taken consecutively in the evenings until any sleeping difficulties disappear. There is also a 2mg dosage available. However, it should be noted that this is currently an off-label treatment.

Are there any side effects?

There are very few side effects of Melatonin when taken in low dosages and used as a short-term remedy. However, as with all prescription medication, side effects are a possibility, although these should be mild if experienced at all. You should nevertheless consult your doctor immediately should any persist.

Common side effects include headache, nausea, grogginess or irritability.

Note: Decisions about treatment are for both the prescriber and the person to jointly consider during the consultation. However, the final decision will always be the prescriber’s.
