ADHD in Cambodia: Methylphenidate Import Rules and Stimulant Access
Cambodia controls ADHD stimulants under the Law on Drug Control. Bring your full supply, a signed doctor's letter, and original packaging.
ADHD in Cambodia: what changes when you travel
Cambodia's Law on Drug Control (2012) classifies methylphenidate as a controlled psychotropic substance, meaning you cannot simply show up at a Phnom Penh pharmacy expecting a refill. Amphetamine-based stimulants have no registered medical use in Cambodia and carry a stricter import status than methylphenidate. Psychiatry is also scarce: only around 50 to 60 psychiatrists serve the entire country, the vast majority based in Phnom Penh.[2][1]
This guide covers what documentation to carry at Cambodian customs, how to find a psychiatrist in Phnom Penh, what to do if your supply runs low, and how heat and humidity interact with your daily schedule. Store your medication list, diagnosis, and emergency contacts in Nomedic before you fly.
Medical disclaimer: This guide is for informational purposes only and does not constitute medical advice. Always consult your specialist before travelling, particularly regarding changes to your treatment schedule and travel insurance.
Key risks for ADHD travellers in Cambodia
Controlled stimulant import with no clear quantity cap
Cambodia's Law on Drug Control (2012) treats methylphenidate as a Table II controlled psychotropic substance. There is no single published import quantity threshold from Cambodian authorities; carry only your personal therapeutic supply (up to 30 days is the widely practised benchmark) with a signed physician letter.[1]
Amphetamine-based stimulants are not registered in Cambodia
Lisdexamfetamine and amphetamine/dextroamphetamine have no registered medical use in Cambodia and their import status is stricter than methylphenidate. Contact the Cambodian embassy in your country before travelling if you take these medications.[3]
No in-country refill for ADHD stimulants
Cambodian pharmacies do not stock ADHD stimulants for retail dispensing. Bring your full supply for the entire trip plus a buffer of at least one week's cover.
Extreme heat and humidity affecting medication storage and sleep
Phnom Penh reaches 35Β°C in April and maintains average humidity of 78% year-round. This disrupts sleep and can affect how your medication timing sits across the day; plan for this before departure.[7]
Very limited psychiatric coverage outside Phnom Penh
Cambodia has approximately 50 to 60 psychiatrists nationwide, concentrated in Phnom Penh. If you are travelling to Siem Reap, Sihanoukville, or provincial areas, access to a prescribing psychiatrist is not guaranteed; telemedicine with your home specialist is the safer fallback.[2]
Preparation checklist
- Contact the Cambodian embassy in your country β For amphetamine-based stimulants in particular, confirm import rules before departure as they differ from methylphenidate.
- Book a pre-travel appointment with your psychiatrist β Confirm your diagnosis letter, medication supply, and whether your dosing schedule needs adjusting for the time zone change (Cambodia is UTC+7).
- Obtain a signed physician letter in English β The letter must state your name, diagnosis, medication name (INN and brand), dosage, and duration of treatment, and confirm the supply is for personal therapeutic use.
- Check your travel insurance policy explicitly names ADHD β Confirm psychiatric consultation, emergency evacuation, and medication replacement are all covered.
- Plan for sleep disruption on arrival β Cambodia is UTC+7; adjust medication timing incrementally before departure with your specialist's guidance.
- Create your Nomedic IPS before departure β Your International Patient Summary stores your diagnosis, medications, allergies, and emergency contacts in a format any clinician worldwide can read offline.
- Pack your full supply plus a one-week buffer β ADHD stimulants are not stocked in Cambodian retail pharmacies; there is no in-country fallback.
- Research medication storage β Keep tablets in original containers away from direct sunlight; Cambodia's heat and humidity make a cool, dry bag essential.
- Store original packaging and keep medications in carry-on luggage β Do not pack stimulant medications in checked baggage; carry them on your person through customs.
- Identify your nearest psychiatrist in Phnom Penh β Save the contact details for Sunrise Japan Hospital (+855 23 260 152) or International SOS (+855 23 216 911) offline.
Documents to carry when travelling to Cambodia with ADHD
Cambodia's anti-drug laws mean documentation is not optional for controlled stimulants[1]. Use the Nomedic app to store a digital copy of every document alongside your IPS.
Your International Patient Summary (IPS)
Your Nomedic IPS contains your ADHD diagnosis, current medications with INNs, allergies, and emergency contacts in a standardised format readable by any clinician worldwide. In Cambodia, where English-speaking psychiatric staff are concentrated in a handful of Phnom Penh clinics, having your clinical picture on-screen in seconds reduces consultation time and the risk of miscommunication.
The IPS also generates a QR code that triage staff can scan without needing you to explain your condition verbally. Store it offline before you travel.

Bringing your ADHD medications to Cambodia
Methylphenidate is a controlled substance under Cambodia's Law on Drug Control (2012), aligned with the 1971 UN Convention on Psychotropic Substances. Carry your entire trip supply in your hand luggage alongside a signed physician letter in English stating your name, diagnosis, INN, dosage, and the duration of treatment. No advance import permit is currently published for methylphenidate, but the physician letter is non-negotiable and must accompany the medication physically through customs.[1]
Amphetamine-based stimulants, including lisdexamfetamine, are not registered for medical use in Cambodia and carry a stricter customs position than methylphenidate. If you take an amphetamine-based medication, contact the Cambodian embassy in your country well before departure to confirm current import rules.[3]
Do not post your medication to Cambodia.
Posting controlled psychotropic substances into Cambodia is prohibited under the Law on Drug Control (2012) and could constitute an importation offence. Always carry your medication in person in your hand luggage.
ADHD medications: brand names, INNs, and Cambodia availability
The table below lists the medications most commonly used in ADHD management and their status in Cambodia. Bring your full supply; none of these are reliably available for retail dispensing in Cambodian pharmacies.
Controlled psychotropic under Cambodia's Law on Drug Control (2012). Personal import permitted with physician letter.
Same controlled status as IR formulation. OROS and modified-release formulations are not interchangeable; bring your specific formulation.
Not a controlled substance under Cambodian drug law. Bring prescription and physician letter. No retail availability confirmed.
Amphetamine-based; no registered medical use in Cambodia. Import status is stricter than methylphenidate. Contact Cambodian embassy before travel.
Non-stimulant. No known local availability. Bring full supply with prescription.
Amphetamine-based; not registered in Cambodia. Seek embassy guidance before attempting to import.
Atomoxetine and MAO inhibitor interactions
Atomoxetine must not be used within two weeks of any monoamine oxidase inhibitor (MAOI). If you are prescribed any new medication in Cambodia, inform the prescribing clinician that you take atomoxetine. Carry your full medication list in your Nomedic IPS so this interaction can be checked at the point of prescribing.
Travelling with medications requiring special handling
Most ADHD medications are solid-dose preparations that do not require cold-chain storage, but Cambodia's heat requires care with storage throughout your stay.
Your medication list, ready to share.
Nomedic stores your medication name, INN, dosage, and frequency, readable by any clinician worldwide.
Healthcare and prescriptions in Cambodia
Cambodia has no universal public health system accessible to international travellers, and no reciprocal healthcare agreement with any country. Private clinics in Phnom Penh provide the most reliable English-language care.
A private psychiatric consultation at facilities such as Sunrise Japan Hospital or International SOS costs $50 to $150 (~β¬46 to ~β¬138) for an initial appointment. Foreign prescriptions are not accepted at Cambodian pharmacies; any new prescription must be issued by a locally licensed physician.[5]
ADHD stimulants are not stocked at retail pharmacies in Cambodia. Controlled psychotropic substances can only be dispensed under a licensed Cambodian physician's prescription, and even then availability at hospital pharmacies is not guaranteed. Do not rely on finding methylphenidate locally; bring your full supply.[1]
ADHD stimulants are dispensed differently in Cambodia
If you need urgent medical review in Phnom Penh, go to Sunrise Japan Hospital or International SOS rather than a retail pharmacy. Bring your Nomedic IPS and your physician letter; these will allow the consulting psychiatrist to assess your situation without requiring a full new diagnostic workup.
Finding an ADHD specialist in Cambodia
Psychiatrists (αααααααααα·αα α·ααααα·ααααΆ) in Cambodia are concentrated almost entirely in Phnom Penh. Cambodia has approximately 50 to 60 psychiatrists for a population of over 17 million; walk-ins are not the norm and wait times at private clinics can be same-day to several days depending on demand.
Sunrise Japan Hospital (+855 23 260 152), International SOS (+855 23 216 911), and the Transcultural Psychosocial Organization (TPO Cambodia, +855 23 884 049) are the primary options. If you are travelling outside Phnom Penh, use telemedicine with your home specialist as the primary support pathway. Find a specialist using Nomedic's provider search before you travel and save contact details offline.[2]
Search for providers near your destination
Use Nomedic's provider search to find ADHD specialists in Cambodia. Save the address and phone number offline before you travel.
If you run out of or lose your medication in Cambodia
A lost or depleted supply of ADHD stimulants in Cambodia cannot be replaced at a pharmacy counter. Act on the steps below as soon as you realise the problem.
Managing heat, humidity, and sleep disruption day to day
Cambodia's average annual humidity in Phnom Penh is 78%, with temperatures reaching 35Β°C in April. The combination of heat and humidity disrupts sleep quality, which in turn affects how consistently your medication schedule operates.[7]
Plan your medication timing before arrival: Cambodia is UTC+7, so adjust incrementally in the days before your flight rather than switching abruptly on arrival day. Use air-conditioned spaces during the hottest hours (11 am to 3 pm) to reduce sleep-quality impact the following night.
Cambodian guesthouses and hotels almost universally provide air conditioning; confirm this when booking accommodation in smaller towns. Tap water is not safe to drink in Cambodia, so factor in hydration from sealed bottled water throughout the day, as dehydration compounds fatigue.
Fatigue from heat is not a sign your medication has stopped working
If you feel more fatigued than usual in Cambodia's heat, this is a recognised physiological response to tropical conditions, not a medication failure. If symptoms persist beyond 48 hours after moving to a cooler environment or returning to a controlled indoor space, seek medical review and follow the guidance in the Emergency tab.
Khmer phrases for clinicians
Show your Nomedic IPS first, it removes the need to explain your diagnosis verbally. If verbal communication is needed:
“αααα»αααΆαααααΊ ADHD (Attention Deficit Hyperactivity Disorder)”
I have ADHD (Attention Deficit Hyperactivity Disorder).
“αααα»αααααΌαααΆααααα½αααΈαααααααααα·αα α·ααααα·ααααΆ”
I need help from a psychiatrist.
“αααα»αααα½αααΆαααααΆα methylphenidate αααααΆαα ADHD”
I take methylphenidate for ADHD.
“αααα»αααΆααααααΆαα αααα»αααααΌαααΆααααα½α”
I have lost my medication. I need help.
“αααααΈαααααααα·ααααα»ααα α―ααΆ?”
Where is the nearest hospital?
“αααα»αααααΌαααΆαααΆαααααααααααααααΆααααααΆαα”
I need an emergency supply of medication.
Insurance considerations
What to know about travel insurance
Policies that cover 'pre-existing conditions' broadly may still exclude ADHD-specific treatment costs. Private psychiatric consultations in Phnom Penh run from $50 to $150 (~β¬46 to ~β¬138) per session, and emergency medical evacuation to a higher-level facility can exceed $30,000 (~β¬27,600).
What to look for in a policy
Not just 'pre-existing conditions covered'. Your condition should be named on the schedule.
Covers repatriation to your home country if local care is insufficient.
Covers emergency replacement if your medication is lost, damaged, or delayed in transit.
So someone can communicate with Cambodian clinicians on your behalf in Khmer or English.
What to declare at application
Declare thoroughly. Incomplete disclosure can invalidate your entire policy, not just the ADHD-related claim.
State whether your diagnosis is inattentive, hyperactive-impulsive, or combined presentation, as insurers may classify these differently.
Use the INN (methylphenidate, atomoxetine, lisdexamfetamine) alongside the brand name.
Include any periods of hospitalisation or medication adjustment in the past 12 months.
Declare comorbidities including anxiety disorder, depression, or sleep disorder if you have a formal diagnosis.
Your policy number and emergency assistance line, saved alongside your IPS and accessible offline.
Cambodia has no reciprocal healthcare agreement with EU or EEA countries. An EHIC or GHIC card provides no entitlement to subsidised care in Cambodia. Comprehensive private travel insurance is essential for all international travellers.
Emergency protocol
Getting to the right care quickly
A psychiatric emergency in Cambodia requires you to reach a private hospital with English-speaking clinical staff. Recognise the difference between a difficult day and a genuine emergency: persistent inability to function, severe distress, or behaviour that puts you or others at risk warrants emergency care. Contact your travel insurer's 24-hour line first so they can coordinate care and authorise costs.
When you arrive, follow in order
Full clinical picture in seconds, no verbal explanation needed.
Hand your phone to the triage nurse:
αααα»αααΆαααααΊ ADHD α αΎααααα»αααααΌαααΆααααα½αααΈαααααααααα·αα α·ααααα·ααααΆ
I have ADHD and I need help from a psychiatrist.
Tell the clinician the INN of your medication, the dose, and when you last took it, this information is in your Nomedic IPS.
Sunrise Japan Hospital and International SOS can provide English-language interpretation; for Khmer-only facilities, your travel insurer's assistance line can connect a phone interpreter.
Calls and location
Ambulance, police, and fire in Cambodia: call 112. The nearest major emergency departments for international travellers in Phnom Penh are Royal Phnom Penh Hospital and Sunrise Japan Hospital. If you are outside Phnom Penh, call International SOS (+855 23 216 911) for evacuation coordination.
In hospital
Methylphenidate and other stimulants interact with several anaesthetic agents and cardiovascular medications. If you are admitted for any reason, ensure the treating clinician sees your Nomedic IPS before any procedure is initiated.
After any emergency
Before you leave the hospital if possible.
Required for insurer reimbursement and continuity of care.

Frequently asked questions
Is methylphenidate legal to bring into Cambodia?
Methylphenidate is legal to bring into Cambodia as a controlled psychotropic under the Law on Drug Control (2012), provided you carry a signed physician letter confirming the medication is for your personal therapeutic use. There is no official published import quantity limit, but restricting your supply to a 30-day personal supply is the widely practised safe benchmark.[1]
Can I bring Vyvanse or Adderall into Cambodia?
Lisdexamfetamine (Vyvanse) and amphetamine-based medications (Adderall) have no registered medical use in Cambodia and carry a stricter import status than methylphenidate. Contact the Cambodian embassy in your country before departure to confirm current rules; do not attempt to bring these medications without prior written confirmation.[3]
Do not post stimulant medications to Cambodia
Postal import of controlled psychotropic substances is prohibited under Cambodia's Law on Drug Control (2012).
Are ADHD medications available in Cambodian pharmacies?
ADHD stimulants are not stocked at retail pharmacies in Cambodia. Even in Phnom Penh, they can only be dispensed under a licensed Cambodian physician's prescription, and hospital pharmacy availability is not guaranteed. Bring your full supply for the entire duration of your trip.
How can I communicate my ADHD diagnosis in an emergency in Cambodia?
Show your Nomedic IPS first. If verbal communication is needed:
“αααα»αααΆαααααΊ ADHD”
I have ADHD.
“αααα»αααα½αααΆαααααΆα methylphenidate”
I take methylphenidate.
Does Cambodia's heat affect how ADHD medication should be stored?
Phnom Penh's average annual humidity reaches 78% and temperatures can peak at 35Β°C in April. Most solid-dose methylphenidate and atomoxetine formulations should be stored below 25Β°C, which means relying on air-conditioned accommodation is essential rather than optional.[7]
Storage tip
Keep tablets in a sealed, labelled container in a cool bag or air-conditioned room. Never leave medications in a parked vehicle or on a windowsill in direct sunlight.
Do I need special travel insurance to visit Cambodia with ADHD?
Standard travel insurance policies often exclude pre-existing psychiatric conditions. In Cambodia, where there is no public health safety net for international travellers, a policy that explicitly names ADHD as covered is essential. Private psychiatric consultations cost $50 to $150 (~β¬46 to ~β¬138), and medical evacuation to Singapore or Bangkok can exceed $30,000 (~β¬27,600).
Declare thoroughly
Subtype, current medication, last episode, associated conditions. Incomplete disclosure invalidates the entire policy.
