MalaysiaTravelling with ADHD medication: rules, permits and documents
AsiaLast checked 31 Jul 2026High confidenceHow we rate a record
Every medication we track can come into Malaysia on your prescription, up to 30 days' supply, carried in original packaging.
Serious penalties: Mandatory death penalty for trafficking under the Dangerous Drugs Act 1952; possession above statutory thresholds triggers a trafficking presumption.
By medication
Brand names first, generic in brackets. Each line resolves the drug class rule below, plus anything Malaysia records specifically for that medication.
- Vyvanse (lisdexamfetamine)Prescriptionmax 30 days' supply
Listed as a psychotropic substance (Poisons Act Third Schedule) with no '(DD)' marker on the Poisons List, so reg 4(2)(a) is its exemption and covers both directions. Not listed in the 1989 Second Schedule — the regulation 9 export-authorisation requirement does not appear to reach it specifically. explicit
- Ritalin, Concerta (methylphenidate)Prescriptionmax 30 days' supply
A Poisons Act Third Schedule psychotropic substance (no '(DD)' marker on the Poisons List), so reg 4(2)(a) is its exemption and covers both directions. Separately named in the Psychotropic Regs' 1989 Second Schedule — requires a foreign-issued export authorisation on import from a Convention-party country (regulation 9), separately from the general personal-use exemption. explicit
- Dexamphetamine (dexamfetamine)Prescriptionmax 30 days' supply
A Dangerous Drug under the DDA, not a Poisons Act psychotropic substance: the Poisons List reads 'Dexamphetamine (DD); its salts', the DDA First Schedule Part III names Amphetamine and extends to 'the isomers... of the drugs in this Part', and the Poisons Act Third Schedule (current to P.U.(A) 248/2026) does not list it. Its traveller exemption is therefore DDA s.25, not reg 4(2)(a): arrival only, with a mandatory declaration of possession as soon as possible on arrival, and no numeric quantity in the statute itself. Status unchanged (legal_with_prescription). Whether reg 9's foreign export-authorisation requirement still reaches it is an unresolved 1989-vs-2026 conflict recorded in Gaps. explicit
- Strattera (atomoxetine)Prescription
Atomoxetine (Strattera), guanfacine ER (Intuniv) and viloxazine (Qelbree) are not internationally scheduled under the 1971 Convention, so they fall outside the INCB controlled-substance travel rules. Carry them with a normal prescription in original packaging; no import permit is required unless a specific national exception applies.
- Adderall (mixed amphetamine salts)Prescriptionmax 30 days' supply
Same as dexamfetamine — a Dangerous Drug under the DDA, not a Poisons Act psychotropic substance: DDA First Schedule Part III closes with 'The salts of the drugs listed in this Part...', and the Poisons List entry reads 'Amphetamine (DD); its salts'. Exemption is DDA s.25: arrival only, declaration mandatory. For reg 9 purposes it is explicitly caught by the 1989 Second Schedule's paragraph 3 ('Any preparation, solution, compound, mixture or product containing one or more of the substances specified in paragraphs 1 and 2 of this Schedule'), not merely by an interpreted reading of paragraph 2 — subject to the same unresolved conflict as dexamfetamine. explicit
- Intuniv (guanfacine)Prescription
The same rule as Strattera above.
- Qelbree (viloxazine)Prescription
The same rule as Strattera above.

Connecting through Malaysia
No official Malaysian source (Royal Malaysian Customs Department, Ministry of Health Pharmaceutical Services Division, or Malaysia's INCB country submission) specifically addresses passengers who stay airside at a Malaysian airport (e.g. KLIA) in international-to-international transit without clearing immigration. Malaysia's 2024 INCB traveller-regulations submission sets out the 30-day personal-supply rule for narcotic drugs and psychotropic substances but has no note on transit or transhipment passengers; it only covers documentation for entry. The Ministry of Health's 'Traveller's Guide to Bringing Medication into Malaysia' page, which would likely cover this, could not be accessed. The Dangerous Drugs Act 1952 text itself could not be checked to see whether its definition of 'import' covers airside transit. Because no official source confirms this either way, the status is 'unclear'.
If you clear immigration: No official source found carving out a transit exemption. If you clear Malaysian immigration for a connection or overnight stay (e.g. via KLIA), the ordinary entry rules described in Malaysia's own MOH/INCB guidance apply in full: all three ADHD stimulant classes are permitted for personal use up to a 30-day supply under the Dangerous Drugs Act 1952 s.25 self-declared traveller exemption, provided you carry a valid prescription and doctor's letter and declare at Customs if asked. No advance permit is needed for entry, so a landside transit passenger's practical requirements should be the same as any other arriving traveller.
- Staying airside, never clearing immigration:
- no official guidance found, so assume the full entry rules apply. No Malaysian source addresses staying airside. The only air-transit exemption in the Dangerous Drugs Act covers aircraft that pass over without landing, so a passenger on the ground at KLIA is inside the Act's transit regime, and the psychotropic regulations ask for a foreign export authorisation to accompany methylphenidate 'on import or while in transit' with no traveller carve-out. Do not read the silence as permission.
- Clearing immigration for a layover:
- the full entry rules apply. No permit exists for personal supplies. Clearing immigration means the entry rules: at most one month's supply, declare dangerous-drug medication (dexamfetamine, mixed amphetamine salts) at the border on arrival, and carry the prescription or doctor's letter in English or translated.
- Changing airports:
- the full entry rules apply. Changing airports (KLIA to Subang) forces a full clearance, so the entry rules apply. No separate transfer rule is published.
- Overnight layover, leaving the airport:
- the full entry rules apply. Leaving the airport means clearing immigration and customs. The one-month personal-use exemptions carry no minimum-stay condition.
- Checked bag travelling without you:
- no official guidance found, so assume the full entry rules apply. Not addressed by any source. The personal-use exemptions are written around a person arriving with the medicine in their possession, so a bag moving without its passenger falls back on the consignment rules, which require licences and accompanying export authorisations.
