Prescription requirements eased on over-the-counter melatonin tablets

From mid-year, many Australians won’t need a script for melatonin: a popular pill for frequent flyers in combatting jet lag.

Prescription requirements eased on over-the-counter melatonin tablets

Australia’s Therapeutic Goods Administration (TGA) is easing restrictions on some melatonin products from June, making these available over the counter at pharmacies, rather than by prescription.

While melatonin supplements are most often used as a treatment for insomnia, such tablets have long been popular with regular travellers as well in helping manage and minimise the impacts of jet lag.

The body naturally produces melatonin at night, or in the absence of daylight. Some use melatonin supplements to nudge this process along and help get to sleep: particularly after crossing time zones to help the body adapt.

For many years melatonin supplements have only been available by prescription in Australia, being classified by the TGA as a ‘Schedule 4’ medicine.

But as of June 1 2021, “melatonin in modified release tablets containing 2mg or less of melatonin … in packs containing not more than 30 tablets” moved to Schedule 3: ‘Pharmacist Only Medicine’.

Under-55s will still need a prescription

The redesignation comes with a notable catch: pharmacists will only be able to supply melatonin without a prescription to “adults aged 55 or over”.

Anybody younger than 55 would still require a script from their doctor – as would those requesting a dose stronger than 2mg, as well as for any melatonin supplement other than in a “modified-release tablet”.

Modified-release pills are designed to delay the delivery of a drug inside the body after being taken.

The human body normally secretes melatonin at night to help maintain sleep, although this declines with increasing age, reflected by the 55+ restriction on supply in pharmacies.

“(We) have not identified any compelling evidence which establishes that melatonin can be safely supplied to consumers, by a pharmacist, outside the current approved indications, which include a restriction to individuals aged 55 years and over,” the TGA advises.

Melatonin more commonly available overseas

While Australia has kept melatonin supplements under lock and key, many other countries make melatonin readily available in pharmacies.

In the United States, for example, melatonin is available on chemist shelves, including stronger doses such as 5mg.

Some find a 5mg dose more effective against jet lag than the 2mg modified-release pills, as will become available in Australian pharmacies prescription-free.

New Zealand has also recently reclassified melatonin as a pharmacy-only medicine, covering standard doses of up to 3mg and modified-release tablets up to 2mg when sold to adults aged 55 years and over.

Some Australian travellers choose to purchase these items overseas and bring them home to Australia under what’s known as the “traveller’s exemption”, although strict conditions apply.

Melatonin and the “traveller’s exemption”

The Australian Government’s Office of Drug Control (ODC) advises that “Australian residents returning from holidays can bring in most medicines and medical devices in their accompanied baggage under the traveller’s exemption.”

That exemption allows travellers to carry medicine for their own personal use, including medicines obtained overseas such as melatonin, although restrictions apply.

“Australian residents require a valid prescription from an Australian doctor for the medication they are travelling with,” says the ODC, or “a letter from your doctor that states you are under their treatment and that the medication(s) you are carrying have been prescribed for your personal use.”

Medicines brought into Australia should also be kept in their original packaging, with a dispensing label.

At most, a traveller can carry a three months’ supply under the exemption, and they must also “declare all medication to Australian Border Force upon arrival”: a requirement that the ODC lists in bold.

The Australian Medical Association (AMA) adds that “Australians are purchasing stronger melatonin products from overseas suppliers and this can create a safety risk if the country of origin does not have the same or better standards or regulation as Australia.”

Australia’s federal Department of Health underscores that “it is against the law to bring medicines and medical devices into Australia to give to someone else,” including supplements such as melatonin purchased in overseas pharmacies.

Well said @cbourl. Not gonna go deep into it, but we have a general political culture that doesn't reside a high degree of trust in an individual Australian's own judgement, risk management and self-responsibility (i.e. "common sense"). Therefore, our pollies and bureaucrats regulate all manner of risk - real and imagined - often to a degree that is embarrassing to explain to foreign colleagues and friends. And we the public will unthinkingly accept it 99% of the time. As Hamish & Andy once said: "If it's 'fun', we ozzies will find a way to kill it".

Indeed. One of the benefits of a stop in Hong Kong was a walk over to Fanda to stock up on all the good stuff.

100-200 tablets of 10mg over the counter at US outlets for about $15. Anything less than 10mg a waste of time.

As a doctor, I can tell you that there is very little evidence that melatonin works any better than placebo, and where there is, it is for the 5 mg dose.  Personally, I find them useless.  If you think the tablet you take will help you sleep, then it will.  (My late mother-in-law swore that Panadol helped her sleep!)

It is possible to import melatonin tablets up to 12 mg tablets.  But you will need a US shipping address which will forward it to you.  It gets checked at Customs (you will get an email asking about the contents).  So far I have had no problems.  Anything less than 10 mg does nothing for me.  My medico specialist partner does not believe in it but it helps me sleep when I have a bad night.

Yes, using a forwarding service is very reliable for a lot of products you can't get in Australia, even just some things on Amazon or US retail specials which are only available in the US. I find 5mg is okay but 10mg really does it for me, knocks me out super-fast.
