What is Melatonin used for?

Our Melatonin 3mg film-coated tablets are licenced specifically for short-term, jet lag-related insomnia in adults aged 18 or older.

Jet lag commonly occurs when travelling across several time zones in an easterly direction. The difference in time between your departure and arrival locations can disturb your sleep, digestion and thinking processes. It can also cause you to feel sleepy during the day or struggle to fall sleep at night.  

What is Melatonin?

Melatonin is a naturally occurring hormone that helps control how and when you sleep. Generally, the level of Melatonin in your body automatically rises at night (after it gets dark) and then returns to lower levels during the day.  

Like any naturally occurring hormone, Melatonin production can be affected by a range of short-term lifestyle factors.   

What does Melatonin do?

Taking Melatonin adds to your body’s natural supply, and it can help you fall asleep faster. It can reduce the impact of jet leg-related insomnia by up to a day and help your sleep get back into a regular rhythm when travelling across multiple easterly time zones.  

How long does Melatonin take to work?

Melatonin for jet lag-related insomnia is a short-term treatment and should only be taken for a maximum of 5 days in a row. Within that time it should help your sleep get back into a regular rhythm.

You don’t need to start taking Melatonin until you arrive at your destination.  

Once you arrive at your destination you should take your first dose of Melatonin at your usual bedtime – continue taking it at this time each night you take it (up to a maximum of 5 nights in a row).  

For maximum benefit, and to reduce any daytime side effects, you should only take Melatonin after 8pm and before 4am.

How to use Melatonin 3mg 30 tablets for jet lag

Melatonin dosage

Melatonin 3mg film-coated tablets should be taken ONCE daily for a maximum of 5 days in a row.

If the effect is inadequate, two 3mg tablets can be taken at the same time.

How to take Melatonin

Once you arrive at your destination you should take your first dose of Melatonin at your usual bedtime – continue taking it at this time each night you take it (up to a maximum of 5 nights in a row).  

For maximum benefit, and to reduce any daytime side effects, you should only take Melatonin after 8pm and before 4am.

The tablets should be swallowed whole with liquid and food shouldn’t be consumed 2 hours before or 2 hours after taking Melatonin tablets.  

Melatonin and alcohol, caffeine and recreational drugs

Melatonin shouldn’t be taken with alcohol as the combination might cause you fall into a deep sleep and have difficultly waking up or breathing properly.

Drinks that contain caffeine - tea, coffee, soft drinks or energy drinks – have the opposite effect of Melatonin and can stop it working properly.  

Melatonin shouldn’t be taken with recreational drugs.  

Drugs like cannabis, heroin or methadone can increase Melatonin’s sleep-inducing effects and might cause you to fall into a deep sleep and have difficultly waking up.

Drugs like cocaine or amphetamines are stimulants and have the opposite effect of Melatonin and might cause it to stop working.
