Will your medication clear customs?
Enter your medication, origin, destination, and trip length. We return a customs reading for the destination regulator — Japan (MHLW), UAE (MOHAP), Singapore (HSA), the US (CBP/DEA), the UK (Home Office), or the Schengen Article 75 framework — with the documents you must carry. This is a rules summary, not legal or medical advice.

How the same ADHD treatment is treated at one destination (Japan)
Whether a prescription drug clears customs depends on the destination's drug law, not on having a valid prescription. The clearest example: amphetamine/dextroamphetamine (Adderall) is banned outright in Japan — no import permit exists, even with a foreign prescription. Lisdexamfetamine (Vyvanse) is different: it is importable into Japan with advance permission as a "Stimulants Raw Material". Most controlled drugs sit in the middle — allowed if you carry a prescription and, for some destinations, an advance permit.
| Medication | Japan status | What you must do |
|---|---|---|
| Adderall (amphetamine) | Prohibited | Cannot be imported — no permit available; do not carry it |
| Vyvanse (lisdexamfetamine) | Controlled | Importable with MHLW advance permission, applied for before travel |
| Oxycodone | Controlled (narcotic) | Yakkan Shoumei import certificate required |
These three rows show why the checker resolves your brand name to its active ingredient before applying any rule — Adderall and Vyvanse give opposite verdicts at the same border. The verdict stamp cites the exact regulator and the date that rule was last checked.

How verdicts are produced
Each verdict is a deterministic lookup against a versioned rules table built from the destination country's drug regulator. We apply a four-step formula: active-ingredient resolution, per-country status (prohibited, controlled, prescription-only, over-the-counter), a supply-days check against your trip length, and Schengen Article 75 evaluation for intra-Schengen travel. It is a rules summary, not legal advice — verify with the embassy before you travel.
- Active-ingredient resolution: brand names (e.g. Adderall, Vyvanse) are mapped to their generic name before lookup, because brands sharing a class can have opposite verdicts (Adderall is prohibited in Japan; Vyvanse is importable with permission).
- Per-country status: prohibited, controlled (with or without an advance permit), prescription-only, or over-the-counter. Sources include MHLW (Japan), MOHAP (UAE), HSA (Singapore), CBP/DEA (United States), and the UK Home Office.
- Quantity check: trip length vs. a per-trip supply allowance. The US 50-dosage-unit limit (DEA 21 CFR 1301.26) caps how much of a controlled substance a US resident may bring back from abroad; it does not apply to medication obtained in the US under a US prescription, and the rule states no numeric cap for non-residents.
- Schengen Article 75 applies between Schengen members for trips up to 30 days; longer trips require the destination country's national permit route. The certificate is authenticated by the health authority of your country of residence and is valid for up to 30 days.
Advisory only — verify with the embassy
This tool provides an orientative rules summary only. It is not legal or medical advice. Border-control practice and pharmaceutical regulation change without notice, and individual customs officers retain discretion at the point of entry. Always cross-check with the destination country's regulator or embassy before travelling, and carry the original prescription, original packaging, and a doctor's letter.
Frequently asked questions
- Can I bring my ADHD medication to Japan?
- It depends on the exact drug. Amphetamine/dextroamphetamine (Adderall) is prohibited in Japan and there is no import permit for it — Japan's Narcotics Control Department lists amphetamine among substances no traveller may import even with a prescription. Lisdexamfetamine (Vyvanse) is treated differently: it is a "Stimulants Raw Material" you can import with advance permission applied for before you travel. Methylphenidate (Ritalin, Concerta) is controlled and generally needs a Yakkan Shoumei certificate. Resolve your brand name to its active ingredient before assuming a verdict.
- Is having a valid prescription enough to clear customs?
- Not always. A prescription is necessary but not sufficient. For prohibited drugs (e.g. amphetamine in Japan) no prescription helps. For controlled drugs, several countries also require an advance permit (UAE MOHAP, Singapore HSA, a Japanese Yakkan Shoumei, or a Schengen Article 75 certificate) in addition to the prescription. Always carry the original prescription, the original packaging, and where possible a doctor's letter.
- Do I need a UK licence to travel with a controlled medicine?
- Usually not. The UK Home Office requires a personal import/export licence only for more than 3 months' supply of a controlled drug (or for Schedule 1 drugs). For up to 3 months you can travel with a prescription or a letter from your prescriber and the original packaging. Most trips fall under the 3-month threshold and need no licence.
- Is the US 50-pill customs limit going to apply to me?
- The 50-dosage-unit cap (DEA 21 CFR 1301.26) limits how much of a controlled substance a US resident may bring back into the country when it was obtained abroad for personal use. It does not apply to controlled medication you obtained in the United States under a US prescription, and the regulation states no numeric cap for non-residents (who must still meet the other rules — declare at customs, original container). Either way, declare controlled substances at customs and carry the original prescription.
- What is a Schengen Article 75 certificate and when do I need one?
- When you travel between two Schengen countries carrying a controlled medicine, Article 75 of the Schengen Convention provides a certificate that lets you cross internal borders. It is issued and authenticated by the health authority in your country of residence and is valid for up to 30 days. For trips longer than 30 days, or when your origin is outside Schengen, you must use the destination country's national permit route instead.
- What documents should I always carry with prescription medication?
- Carry the medication in its original, labelled packaging; the original prescription (and a translated copy where the destination's language differs); and, for controlled drugs, any required permit — a UAE MOHAP permit, a Singapore HSA approval, a Japanese Yakkan Shoumei, or a Schengen Article 75 certificate. A signed letter from your prescriber stating the diagnosis, drug name (generic), and daily dose helps at the red channel.
- Why does this tool sometimes say "consult embassy"?
- When the medication you enter is not in our per-country rules table for that destination, the tool does not guess a number — it returns "consult embassy" rather than invent an allowance. This is deliberate: in a domain where the cost of a wrong answer can be detention or an abandoned course of treatment, no answer is safer than a fabricated one. Contact the destination's regulator or embassy for those cases.
Customs-ready carry kit
Officers care about packaging and paperwork as much as the medication itself. Three things seasoned travellers carry through the red channel:
- Loose pills invite questions — keep doses labelled and inspectable — compare labelled travel pill organizers on Amazon
- Insulin and biologics need a cold chain that survives a long-haul layover — see insulated medication travel cases on Amazon
- Prescription, doctor's letter, and import permit should outlive the bag search — browse travel document organizers on Amazon
