Taking medication overseas from Australia: check this before you pack
The medicine in your bathroom cabinet is legal in Australia. That tells you nothing about the country you're flying to.
By Jamie · 8 min read · Published 30 August 2026
Of everything I check before a trip, medication is the one I refuse to leave until the last week. Not insurance, not visas - medication. Because it's the only item on the packing list where "it's fine at home" can mean a border interrogation somewhere else, and because the fix always takes weeks, never days.
Here's the fact that reframes the whole topic: Australia approves medicines; other countries don't inherit that approval. Japan treats the pseudoephedrine in ordinary Sudafed as a stimulant under its Stimulants Control Act. The UAE treats codeine - the ingredient in stronger Panadeine-style painkillers - as a controlled substance needing a permit. Indonesia treats some of what an Australian GP prescribes routinely as narcotics that cannot legally enter the country at all. None of this is exotic; it applies to cold and flu tablets, painkillers, ADHD medication and sleeping tablets that hundreds of thousands of Australians carry every day.
The good news is that the system is entirely navigable if you start early. Here's how I work through it.
The four rules that apply everywhere
Before any country-specific homework, four habits cover you almost everywhere on earth.
Keep everything in its original packaging. The box with the pharmacy label tying the medicine to your name is your evidence that it's a prescription, not contraband. Loose pills in a travel organiser are the single easiest way to turn an innocent medicine into a customs conversation.
Carry a letter from your GP. One page listing each medicine, its strength and your daily dose, on letterhead. Services Australia says to carry exactly this, and every country I cover below either requires it or is satisfied by it. Ask for it at your regular appointment; it takes your GP two minutes.
Take no more than three months' supply of PBS medicines. That's the legal ceiling - PBS medicine can't be taken or posted overseas beyond three months' continuous supply, and once you've left, the PBS stops entirely: no posting top-ups from home, no subsidised refills abroad. Longer trips mean a plan with your doctor, not a bigger bag.
Pack it in your carry-on. Checked bags go missing; the medicine that keeps you well shouldn't be in one. This also puts the original packaging and the letter in the same bag you'll be standing with at immigration.
Do those four things and you've handled the majority of destinations. The rest of this guide covers the countries that ask for more.
Japan: the one that surprises everyone
Japan catches more Australians than anywhere else, because the restricted items are so ordinary.
Pseudoephedrine is prohibited. The Australian Embassy in Tokyo is blunt about it: pseudoephedrine, found in standard Sudafed and many of the stronger cold and flu tablets pharmacies keep behind the counter, is banned in Japan, and travellers found carrying it can be detained. Some Vicks inhalers fall foul of the same stimulant rules. Leave them at home and buy a Japanese equivalent from any pharmacy there if you need one.
Amphetamine-based ADHD medication cannot enter at all. The embassy names dexamphetamine - routinely prescribed in Australia - on the banned list, with no permit available. Methylphenidate (Ritalin, Concerta) is different: it can be brought in with the right paperwork. Lisdexamfetamine (Vyvanse) needs advance permission from Japan's health authorities. If you or your child takes ADHD medication, this is a conversation with your prescriber weeks before you book, because the answer may be switching medication temporarily or applying for the permit.
Codeine-based painkillers need a Narcotic Certificate. Japan classes codeine, morphine and oxycodone as narcotics, and carrying them without the certificate means confiscation at best. That covers the Panadeine Forte in a lot of Australian bags.
More than one month of any prescription medicine needs an import certificate. It's called a Yunyu Kakunin-sho, and Japan's customs rules set out the quantity thresholds; the standard advice is to apply at least two weeks before you fly. Under a month's supply of ordinary prescription medicine travels on the four rules above alone - which is why most two-week holidays need no paperwork at all.
The UAE: free permit, but get it before you board
For Dubai or Abu Dhabi - including a stopover where you leave the airport - controlled medicines need approval before travel. The big names on the controlled list are exactly the ones Australians carry: codeine in stronger painkillers, tramadol, and most sleeping tablets and anxiety medications.
The process is better than its reputation: the Ministry of Health and Prevention issues personal import permits online, free, for up to three months' supply of a controlled medicine with your prescription and doctor's letter attached. The mistake isn't the process; it's finding out about it at the boarding gate.
Singapore: two weeks' notice for controlled medicines
Singapore's rule is clean. Under three months' supply of ordinary prescription medicine needs no approval - the four rules cover you. Anything containing a controlled substance (sleeping tablets, strong painkillers, ADHD medication) needs approval from the Health Sciences Authority before you arrive, and HSA asks for the application at least two weeks ahead. Singapore is also a place where I'd never test the line: the penalties framework around controlled substances there is among the world's strictest, and "it was prescribed at home" is not a defence for something you didn't clear.
Indonesia and Bali: the hardest line
Indonesia draws the line most Australians don't expect: medicines classed as narcotics - including codeine-based painkillers - are prohibited from entry, prescription or not. Psychotropic medicines (the category covering many sleep, anxiety and ADHD prescriptions) are capped at a declared supply with documentation; ordinary medicines travel on the prescription and letter. Given how heavily Indonesian law punishes drug offences and how much sits in the "check first" category, my rule for Bali is absolute: every regular medication gets checked against the Indonesian embassy in Canberra before booking, and codeine stays home - swap the pain plan with your GP.
Every other country: the fifteen-minute check
For anywhere not named above, the check is the same three steps, done four or more weeks out so there's time to act on the answer:
- Read your destination's page on Smartraveller - the health section flags destinations with known medication rules.
- Ask the destination's embassy or consulate in Australia about your specific medicines by name and ingredient. This is the only answer that counts for controlled substances, and embassies answer these emails all the time.
- Cross-check the ingredient, not the brand name. Border officers don't know what Panadeine Forte is; they know what codeine is. Your GP's letter should name the active ingredients for exactly this reason.
Your destination's entry page on this site tells you the visa and arrival-card side of the same trip, and the pre-departure checklist slots the medication check into the eight-weeks-out window where it belongs.
Frequently asked questions
Can I take Sudafed or Codral to Japan?
No, not if it contains pseudoephedrine, which standard Sudafed and many Codral cold and flu products do. Japan prohibits pseudoephedrine products under its Stimulants Control Act, and this applies to over-the-counter medicines that are completely unrestricted in Australia. Buy an equivalent from a Japanese pharmacy after you land instead.
Do I need a letter from my doctor to travel with medication?
Carry one for any prescription medicine. It should list each medicine, its strength, your dose, and name the active ingredients, on your doctor's letterhead. Several countries require it for controlled medicines, and everywhere else it turns a customs question into a thirty-second conversation. Services Australia recommends exactly this for PBS medicines leaving the country.
How much medication can I take out of Australia?
Up to three months' continuous supply of PBS medicines, for your own use, carried with you. More than that cannot legally be taken or posted overseas, and the PBS cannot supply you at all once you have left Australia, so trips longer than three months need a plan with your doctor before you go.
Can I take ADHD medication overseas?
It depends on the ingredient and the country, and this is the medication category with the most traps. Dexamphetamine cannot enter Japan under any circumstances, while methylphenidate can with paperwork. Singapore and the UAE both require advance approval for stimulant medications. Ask the embassy of every country on your itinerary, including transit stops, at least a month out.
What about medicinal cannabis?
Treat it as non-transportable unless the destination's embassy tells you otherwise in writing. An Australian prescription carries no weight in most of Asia and the Middle East, where cannabis products remain illegal regardless of medical status, and penalties are severe. This is one to be pessimistic about by default.
What happens if I run out of medication overseas?
The PBS cannot help you from outside Australia - medicine cannot be posted to you from home beyond the export rules, and Australian subsidies do not apply abroad. You will need a local doctor to prescribe a local equivalent, which is one more reason to carry your GP letter naming active ingredients and doses, and to travel with insurance that covers a doctor's visit.
The bottom line
Book the GP appointment before you book the seats: get the letter, check every regular medicine against your destinations, and apply for any permit with a month in hand. Then put the whole thing behind you and enjoy the trip - which is the entire point of doing it early. The pre-departure checklist holds your place, and your destination's page covers everything else the border will ask of you.
