Bringing US Prescription Medications to France: What's Allowed, What's Controlled, and How to Keep Your Treatment Going

Medication continuity is one of the least-discussed and most practically consequential parts of moving to France as an American. The French pharmacy system is sophisticated, reimbursements are generous once you are enrolled in Assurance Maladie, and most common prescription medications are available in France under a French name or generic equivalent. The complication is concentrated in a specific category: controlled substances. Some medications that Americans take routinely for ADHD, anxiety, pain management, and sleep are classified differently in France, unavailable entirely, or subject to rules that require documentation you need to organize before you leave the US. Getting this wrong at the border, or discovering the problem in month two of living in France when your supply runs out, is an entirely preventable situation. This article explains what you can bring through French customs, how France classifies controlled substances, what exists and what does not in the French system, and what to prepare before departure to keep your treatment uninterrupted. This article is for informational purposes only and does not constitute medical or administrative advice. Healthcare rules and processing times vary: verify current requirements directly with your local CPAM, the ANSM, or a qualified medical professional.

What French customs allows: the general rules for prescription medications

For standard prescription medications, the rules are straightforward. You can bring a personal supply of most prescription drugs into France without prior authorization. The limit is the duration of treatment written on your prescription, and three months of treatment only when you have no prescription at all. If your supply covers more than three months, French customs (Douane) requires you to produce the prescription. The ANSM (Agence Nationale de Sécurité du Médicament et des Produits de Santé) applies the same ceiling to personal imports. For medications classified as stupéfiants or psychotropes the ceiling is lower: the maximum authorized prescription duration, or one month of treatment if there is no prescription.

What the customs officer is looking for: original pharmacy packaging with labels showing your name, the medication name, the prescribing physician's name, and the dosage. Medications in a generic pill organizer without original bottles are a problem. For a short trip, traveling with a neatly organized pill case is usually fine. For a one-way move, bring medications in their original containers, organized clearly, with your doctor's letter or prescription in either English or French.

The doctor's letter is not strictly required for most non-controlled prescription medications, but it dramatically smooths any customs encounter and is essential for controlled substances. The letter should state your name, diagnosis or condition, medication name (generic and brand), dosage, prescribing physician's contact information, and the intended duration of treatment. Having it in both English and a French translation eliminates ambiguity.

In our experience, Americans with well-organized medication documentation pass French customs without incident for the vast majority of standard prescription drugs. The friction points, almost without exception, involve the controlled substance categories described below.

How France classifies drugs: stupéfiants, psychotropes, and the rest

France divides prescription medications into several categories that do not map cleanly onto US DEA scheduling. Understanding this classification is the foundation for knowing what rules apply to your medication.

Médicaments sur ordonnance simply means prescription-only. Most common prescription drugs fall here: blood pressure medications, statins, antibiotics, most antidepressants, most antidiabetics. A French ordonnance from a French doctor is required to dispense them in France, but they are not specially controlled and do not require special documentation for customs.

Stupéfiants (narcotics) are the most strictly controlled category. These require an ordonnance sécurisée, a specially printed security prescription pad that French physicians must use. They cannot be mailed. Quantities are tightly regulated. This category includes opioid pain medications (morphine, oxycodone, fentanyl, methadone), methylphenidate (Ritalin, Concerta), and amphetamine-based stimulants. Contrary to what is often repeated, these medications are not prohibited at the French border when they are part of your own treatment: the Douane allows you to import them provided you carry them personally, in a quantity compatible with personal therapeutic use, and the original valid prescription is mandatory.

Psychotropes (psychotropics) include a broader category of medications that act on the nervous system. Benzodiazepines (Xanax, Valium, Klonopin) fall into this category in France, as do hypnotics like zolpidem (Ambien). They are controlled but treated differently from stupéfiants. They require prescriptions but not necessarily the same level of advance authorization.

The attestation de transport issued by the ANSM is widely misunderstood, and it is worth being precise. The ANSM issues it to people who live in France and are leaving for a country outside the Schengen area whose authorities require such a certificate. It is not a document for entering France: the ANSM states plainly that it does not issue transport certificates for travelers coming to France, and that no French certificate is required for entry. What is mandatory on arrival is the original of your prescription.

Controlled substances and the document you need before departure

If your medication is classified as a stupéfiant in France, the sequence to follow before you leave the US is specific. Do not arrive at Charles de Gaulle or Roissy with a large supply of a narcotic medication without the documentation described here.

First, identify whether your medication is a stupéfiant in France. Consulting the ANSM website directly gives you the French classification. The US Embassy in France and the French Embassy in the US also provide guidance and recommend contacting the French consulate in your jurisdiction before traveling with such medications.

Second, have your US physician write a detailed medical letter. It should include: your full legal name and date of birth, the name of the medication (brand and generic), the exact dosage and frequency, the medical reason for the prescription, the intended duration of treatment, and the physician's license number and signature. This document should be on official letterhead.

Third, do not build your plan around a French authorization document. There is no French permit to apply for before flying to France with your own treatment, and the ANSM does not issue transport certificates to travelers arriving in the country. What the Douane will ask for is the original valid prescription, so carry the original itself rather than a photocopy or a photograph of it.

Fourth, keep the medication and the documentation on you. Stupéfiants and psychotropes can only be imported by personal transport, so they travel with you rather than in a shipment, and keeping them in your carry-on with the prescription is the practical way to satisfy that and to have the documents immediately accessible if asked at customs.

What the competent French authorities actually state: narcotic and psychotropic medications may be brought in for your own treatment, but only if you carry them yourself, only in a quantity compatible with personal therapeutic use, and only with the original valid prescription, which the Douane lists as a mandatory supporting document. Quantities beyond personal use fall outside that allowance, and heavy penalties apply for smuggling, regardless of the traveler's intent.

Medications available in France: what crosses over and what doesn't

The good news for most Americans on standard prescription regimens is that French equivalents exist for the vast majority of common US prescription drugs. The same molecules are often available under different brand names.

The transition to a French prescription typically requires a visit to your médecin traitant (primary care physician) or a specialist, who evaluates your condition and issues a French ordonnance. For most non-controlled medications, this is a relatively straightforward process. Our guide to finding a médecin traitant in France covers the registration process, including how to manage the situation when available appointments are limited.

Adderall and amphetamine-based ADHD medications: the hard reality

This is the medication situation that causes the most disruption for Americans moving to France, and it requires a direct and honest explanation.

The specific US brand Adderall (mixed amphetamine salts) has never been authorized in France, and no French pharmacy can dispense any medication on a US prescription. However, it is no longer true that amphetamine-class ADHD medication is unavailable in France. Lisdexamfetamine, the molecule in Vyvanse, received French marketing authorization in 2025 and is now sold as XURTA (it was previously reachable through a compassionate-access program as Elvanse), and dexamfetamine is available as Tentin, which is authorized only for children and adolescents aged 6 to 17 and not for adults. Both are classified as stupéfiants, are not reimbursed by Assurance Maladie, and are tightly controlled: the initial prescription is reserved to neurologists, psychiatrists, and pediatricians, on a secure prescription (ordonnance sécurisée) limited to 28 days, as set out in the public medicines database.

The most established ADHD treatment in France is methylphenidate, available under brand names including Ritaline, Concerta, Quasym, and Medikinet. Methylphenidate is a stupéfiant in France and requires a secure prescription (ordonnance sécurisée), but it is no longer the only legally available stimulant: since 2025, lisdexamfetamine (XURTA, the same molecule as Vyvanse) is also authorized, as is dexamfetamine (Tentin, for ages 6 to 17 only), with these amphetamine-class options generally used as second-line treatment after methylphenidate.

What you can do: bring a limited personal supply of Adderall to cover the initial period after arrival, carried personally, with your original US prescription and a physician's letter. This gives you time to establish care with the French system. Quantities should correspond to your prescription duration and not exceed what French authorities would consider a reasonable personal supply.

What you cannot do: refill a US Adderall prescription anywhere in France, have additional supplies shipped to you from the US, or expect your US prescription to function as a French one. You will need a French prescription for a French-authorized stimulant, which a French specialist may set up as methylphenidate or, depending on your situation, as lisdexamfetamine (XURTA, the same molecule as Vyvanse) or, for a patient aged 6 to 17, dexamfetamine (Tentin).

The transition process itself deserves specific attention. In France, the initial methylphenidate prescription for adults must be made by a specialist in neurology, psychiatry, or pediatrics, but since September 2021 this no longer has to be a hospital-based doctor: a specialist in private practice (en ville) can now initiate it, which has widened access somewhat. A general practitioner cannot start this treatment. After the specialist initiates the prescription, the GP can renew it under certain conditions.

In practice, specialist waiting lists in France for adult ADHD evaluation are long. In Paris and major cities, waiting times of three to six months for an initial psychiatric or neurological consultation are not unusual. This means the transition planning must begin before you move, not after you arrive and run out of medication. If you are relocating to France and currently take Adderall or Vyvanse, the single most important medication-related step you can take before departure is arranging the maximum possible supply to cover your first months in France, and beginning the process of finding a French psychiatrist or neurologist as soon as you have a French address and CPAM registration.

Other controlled medications: benzodiazepines, opioids, and sleeping medications

For Americans managing anxiety with regular benzodiazepine prescriptions, the transition to France is less abrupt than for Adderall users but still requires careful planning.

Benzodiazepines are available in France but prescribing practices differ from US norms. French physicians typically prescribe shorter courses and are more cautious about long-term use than many US practitioners. An American arriving with a prescription for long-term alprazolam or clonazepam use will find French GPs willing to prescribe, but may encounter more discussion about dosage reduction than they expect. This is not refusal of care but a genuine difference in clinical approach. Bring a generous supply to allow time for establishing care and potentially working through that clinical conversation.

For Americans on chronic opioid pain management, France has equivalent medications available but under strict stupéfiant controls. The French pain management system requires a prescribing specialist for complex opioid regimens. A GP can prescribe short courses for acute pain, but chronic pain management involving sustained-release opioids will require a pain specialist (médecin de la douleur) referral. Bring documentation of your pain condition and treatment history, not just the prescription itself.

Sleep medications (zolpidem/Stilnox) are available in France but they fall under part of the narcotics rules: the prescription must be written out in full on an ordonnance sécurisée, and it cannot cover more than 28 days. French guidance is that treatment should be as short as possible and should not exceed four weeks including the tapering period, with two to five days for occasional insomnia and two to three weeks for transient insomnia. Americans on long-term zolpidem therapy for chronic sleep disorders will need to discuss this with a French GP who may suggest alternative approaches.

Why you cannot mail prescription medications to France

Americans who run out of controlled medications in France sometimes ask whether family members can mail additional supplies from the US. The answer, for controlled substances, is no. Both the ANSM and French customs are explicit that stupéfiants and psychotropes can only be imported by personal transport, which rules out both personal packages and courier services.

For non-controlled prescription medications the position is different, and it is worth knowing rather than guessing. The ANSM allows a private individual to receive a medication by post or express freight without an import authorization when the medication is authorized in the country it is sent from and a copy of the prescription written by a doctor established in that country is presented to customs. That is a narrow path with real paperwork attached, so the safest approach for any critical prescription medication remains to bring a sufficient supply when you travel and have a transition plan in place.

In our experience, Americans who underestimate this point discover the problem acutely: they brought a six-week supply, their French specialist appointment is in week eight, and there is no mechanism to fill the gap from the US. The solution is always the same in retrospect: plan for a longer supply before departure, and start the French system process in the first week of arrival, not the first week of running low.

Planning your medication continuity before you move

The pre-departure window for medication planning is everything. Once you are in France without a sufficient supply, your options shrink considerably. Once you are in France with adequate supply and active engagement with the French healthcare system, the transition is manageable.

The sequencing that works: at least three months before departure, ask your US physician for the longest supply they can prescribe for your ongoing medications. For controlled substances, verify whether ANSM documentation is needed and request it with adequate lead time. Research the French equivalent of each of your medications and note the generic name rather than the brand name, which is often different.

The pre-departure checklist for Americans moving to France covers the full set of pre-departure tasks. Within that list, the medication supply and documentation preparation should sit alongside your visa application, not as an afterthought.

After arrival: register with CPAM as soon as possible. CPAM registration enables French prescription reimbursements. Our post about enrolling in French public health coverage covers the exact steps. Once registered, find a médecin traitant and bring your full medical history, including a list of all current medications with generic names and dosages. For any medication requiring specialist initiation in France, ask your médecin traitant for the referral immediately rather than waiting until supply runs low. The healthcare setup process from arrival through Carte Vitale issuance is covered in our healthcare first steps guide.

Medication is one piece of a much larger first-year picture: visa, healthcare registration, banking, and the rest. If you're still mapping the full move, build your personalized France plan so nothing slips through.

One category needs more lead time than the rest: if you are on hormone therapy, French prescriber rules decide who is allowed to restart it, and our guide to keeping hormone treatment going after you land sets out which specialist you need and how early to book.

Budget for the cost of the medication itself during your first months, not only for the supply logistics. Before CPAM affiliation, French pharmacy prices are yours in full, and a maintenance prescription that costs very little once reimbursed can be a real monthly line item in the interval. Coverage that reimburses prescription costs from day one, whether an expat policy for the pre-CPAM window or a mutuelle once you are affiliated, is what removes that gap. This is a budgeting point, not medical advice: your prescriber and your pharmacist remain the people to consult on the treatment itself.

Common mistakes to avoid

Bringing medications in a pill organizer without original packaging is the most common customs-level mistake. It makes identification of the medication impossible for a customs officer and eliminates the proof that the medication was prescribed to you. Travel with original bottles or packaging for all controlled substances. For daily convenience during the trip itself, a pill organizer is fine alongside the original bottles.

Assuming your US prescription can be filled at a French pharmacy is the second mistake, and the most consequential for controlled substances. A French pharmacist cannot dispense a medication based on a US prescription. The ordonnance must come from a French physician. This applies to every prescription medication, not just controlled substances. The French pharmacy system is covered in detail in our French pharmacy guide, which explains the ordonnance system and what pharmacists can and cannot do.

Waiting until your supply is almost gone to engage the French healthcare system is a third mistake. For most medications, a médecin traitant appointment within your first two weeks in France gives you the transition time you need. For specialist-required medications (methylphenidate for ADHD, complex pain management regimens), the first appointment request should go in your first week in France, not your third month.

What we see most often: Americans who disclosed their Adderall or Vyvanse use to their French médecin traitant, assumed the GP could handle it, and only discovered that France doesn't have the medication and requires a specialist several months into their stay, when urgency had already set in. The earlier you communicate the full picture of your medication needs, the more time the system has to provide you with options.

Practical checklist

Three to six months before departure:

• List all current medications with generic names, brand names, dosages, and prescribing physician

• Identify which medications are controlled substances under French law using the ANSM classification (ansm.sante.fr)

• Request maximum-duration prescriptions from your US physician for all critical medications

• For stupéfiants: plan to carry them personally, with the original prescription (there is no French entry authorization to request)

• Have your US physician write a detailed medical letter for all prescription medications (generic name, brand name, condition, dosage, frequency, physician's credentials)

Immediately before departure:

• Pack all medications in carry-on luggage, in original pharmacy containers

• Carry the original prescription and medical letter accessible, not buried in checked bags

• Note the generic name and approximate French equivalent for each medication you take

• For ADHD medications: mentally prepare for the transition process and research French specialists in your destination city

First two weeks in France:

• Register for CPAM

• Find a médecin traitant and book an appointment; bring the full list of medications and your US medical letter

• For any medication requiring specialist initiation in France (ADHD stimulants, complex pain management): request the specialist referral immediately

• For any medication unavailable in France: discuss transition options with the médecin traitant at the first appointment

When to get help

For most standard prescription medications (antidepressants, blood pressure medications, thyroid medications, basic sleep aids), the French system absorbs the transition smoothly with a médecin traitant appointment and a French ordonnance. Plan for it but do not expect significant friction.

Professional guidance is worth arranging before departure if your medication situation includes: amphetamine-based ADHD treatment (plan the full transition, bring documentation, start specialist search immediately); chronic opioid pain management (French pain specialist referral needed, bring full pain history); or a complex multi-medication regimen where interactions or specialist oversight matter.

If you are carrying a controlled prescription and still need to line up a médecin traitant, a specialist referral, and a French ordonnance in the right order, the full arrival sequence is mapped with the timing each step depends on.

FAQ

Can I bring Adderall to France for my personal use?

You can bring a limited personal supply through French customs with proper documentation: your original US prescription, which is mandatory at the border, and a detailed medical letter from your physician. There is no ANSM attestation to obtain for entering France. However, you cannot refill this supply in France under any circumstances. The specific US brand Adderall (mixed amphetamine salts) is not authorized in France, and no French pharmacy can fill a US prescription, but the molecule in Vyvanse, lisdexamfetamine, is now authorized in France and sold as XURTA (prescribed by a neurologist, psychiatrist, or pediatrician on a secure 28-day prescription, classified as a stupéfiant and not reimbursed), and dexamfetamine (Tentin) is available for ages 6 to 17. Once you have used your supply, you will need to be on a French equivalent. The transition to methylphenidate requires a specialist evaluation and is best initiated as early as possible after arrival.

My antidepressant is prescribed in the US under one brand name. How do I know if the same molecule is available in France?

Search for your medication's generic (International Nonproprietary Name) rather than the brand name. For example, sertraline (generic) = Zoloft in the US = Zoloft or sertraline générique in France. Escitalopram (generic) = Lexapro in the US = Seroplex in France. Most major antidepressants and psychiatric medications are available in France under the same molecule, sometimes a different brand name. Your médecin traitant or a French pharmacist can confirm availability when you present the generic name. Bring the generic name of each medication with you; do not rely on the US brand name being recognized.

Can a French pharmacist give me more of my medication in an emergency if I run out?

For most non-controlled prescription medications, if your French prescription has expired and you cannot immediately reach your médecin traitant, the pharmacist can use the dispensation supplémentaire exceptionnelle: for an ongoing chronic treatment prescribed for at least three months, they can keep you supplied for up to three months, one month at a time, provided the first delivery falls within the month after the prescription expired and they inform your prescriber. This applies to a French prescription that has run out, not to a US one. For controlled substances, including any stupéfiant, a pharmacist cannot dispense without a current valid French ordonnance sécurisée: stupéfiants are excluded from that scheme, as are medications whose prescription duration is capped, such as hypnotics and anxiolytics. This is another reason the supply and specialist engagement planning matters before the situation becomes urgent.

Do I need to declare my prescription medications when entering France?

For standard prescription medications in personal quantities, there is no medication declaration form to fill in when you enter France from the US. What matters is the quantity and the paperwork rather than a declaration: if your treatment runs beyond three months you must produce the prescription for customs, and quantities that go past personal use are not declarable at all, since the Douane treats them as an outright prohibited import. For controlled substances (stupéfiants), the original valid prescription is mandatory rather than something to produce only if asked. Being proactive about having documentation available reduces any customs encounter to a brief check rather than a lengthy discussion.

Conclusion

For most Americans moving to France, medication continuity is straightforward: bring an adequate supply, note the generic names, and transition to French prescriptions through a médecin traitant in the first weeks after arrival. The French system covers most of what the US system covers, often under a different name, at lower cost to the patient once CPAM coverage is established.

The exceptions require specific preparation: amphetamine-based ADHD medications are unavailable in France and need a planned transition; controlled substances require documentation before departure; and specialist-required medications need early engagement with the French referral system.

If your regimen needs a specialist rather than a GP, sequence your CPAM enrollment and referral steps so your prescriptions do not lapse in the gap.
