Australian Border Force has seized 150,000 units of melatonin as part of a crackdown on online supplement imports, leaving thousands of Australians scrambling for sleep aids now classified as prescription-only.
The enforcement highlights Australia's unique approach to supplement regulation. Only in Australia would you need a prescription for melatonin while the rest of the world sells it at corner shops. This crackdown shows how Australia's pharmaceutical protectionism plays out in practice - and how many Aussies were bypassing the system through iHerb.
The ABC reports Border Force intercepted the supplements over recent months as part of increased enforcement of prescription medicine rules. Melatonin has been prescription-only in Australia since 2021, but online retailers like iHerb continued shipping it to Australian customers - until now.
iHerb has updated its website with a disclaimer warning Australian customers that Border Force may seize their orders and demand valid prescriptions. The company is still accepting orders but says it cannot guarantee delivery.
The crackdown has sparked frustration among Australians who relied on imported melatonin. Online commenters on the Australia subreddit expressed anger at what they see as unnecessary regulation protecting pharmaceutical companies' profits.
"You can buy melatonin at any pharmacy in the US, UK, NZ - basically everywhere except Australia. But here you need a prescription and pay $50 for a doctor's visit," one commenter wrote. "It's protectionism dressed up as health regulation."
Another noted: "I've been buying melatonin from iHerb for years. Suddenly Border Force decides to actually enforce the rules and now I'm back to lying awake at 3am."
Melatonin is a naturally occurring hormone that regulates sleep cycles. In most countries, low-dose melatonin supplements are available over-the-counter. Australia requires prescriptions for any melatonin product, arguing that proper medical supervision ensures safety.
But critics say the prescription requirement is about protecting pharmaceutical companies' market share rather than public health. Prescription melatonin in Australia costs significantly more than over-the-counter versions available overseas.
The Therapeutic Goods Administration defended the prescription requirement, saying melatonin can interact with other medications and should be taken under medical supervision. The TGA said the Border Force crackdown was necessary to enforce existing regulations.
"These are prescription medicines under Australian law. Importing them without a prescription is illegal," a TGA spokesperson said. "We're working with Border Force to ensure compliance."
The enforcement comes as Border Force has ramped up scrutiny of supplement imports generally. The agency has seized vitamins, minerals, and other products that contain ingredients banned or restricted in Australia.
For many Australians, the melatonin crackdown represents broader frustration with pharmaceutical regulation. Australia's conservative approach to supplement availability means many products freely available elsewhere require prescriptions here - or are banned entirely.
The iHerb orders that previously slipped through represent a significant market. The 150,000 units seized likely represent only a fraction of total imports, suggesting tens of thousands of Australians were regularly buying melatonin online.
Now those customers face a choice: pay for a doctor's appointment and prescription, or continue ordering online and risk having their packages seized. Some report success with alternative suppliers, but Border Force says it's increasing surveillance of supplement imports.
The crackdown highlights a familiar pattern in Australia: regulations designed to protect public health that critics say primarily protect industry profits. Whether melatonin truly requires prescription-only access, or whether Australia is out of step with international norms, depends on who you ask.
For thousands of Australians trying to manage sleep issues, though, the answer is simple: they were managing fine with imported melatonin, and now Border Force has made that harder. Whether that's protecting public health or pharmaceutical profits remains the question the government doesn't want to answer.
