Taking medication to Portugal: bringing it in and refilling it

This is a topic where the honest answer starts with what is not there. INFARMED, the Portuguese national authority for medicines and health products, publishes a controlled substances section and an import section, and both are written for entities rather than for individuals. The subsections cover wholesale distributors, manufacturers, pharmacies, pharmacists, brokers, mobile pharmaceutical posts and home-dispensing registration. Nothing on those pages addresses a private traveller carrying a personal supply.

Checked on 7 August 2026, we did not find a traveller-facing personal-quantity limit on INFARMED's controlled-substances page, on its import page, or on the SNS 24 traveller kit page. That is an absence on those three pages, not a statement that Portugal has no rule, and it is not a reason to assume anything goes. If your situation is unusual, ask INFARMED directly rather than working from a number you found on a forum.

What those pages do establish is that INFARMED is the competent national authority for authorising the import, export and transit of controlled substances. That matters for the controlled-medicine section below, and it tells you who to write to.

With no published personal-quantity figure to work to, the sensible standard is the one that satisfies any official who asks: the medicines are obviously yours, obviously prescribed, and obviously in the quantity a prescriber intended. In practice that means:

• keep everything in its original packaging with the pharmacy label attached, rather than decanting into a pill organiser for the flight
• carry a copy of the prescription, plus a short letter from your prescriber if the prescription itself is terse
• name each medicine by its international non-proprietary name, the generic active substance, as well as by the brand you know, because brand names differ between the United States, the United Kingdom and Portugal
• keep medicines in hand luggage, and if you are travelling as a family, split the supply across two bags so a lost case is not a lost treatment
• bring a quantity that plainly matches your daily dose and the length of time before you expect to see a Portuguese doctor

A one-page prescriber letter carrying your full name and date of birth as they appear on your passport, the prescriber's name, qualification, address and contact details, and each medicine's generic name, strength, form, daily dose and total quantity covers almost every question that could be asked. It also becomes the document your new Portuguese doctor reads at the first appointment, so it is worth writing once and writing well.

Stimulants prescribed for ADHD, strong opioid painkillers and some sedatives are controlled medicines, and they are handled more tightly than ordinary prescriptions everywhere in Europe. INFARMED is the competent national authority for authorising import, export and transit of controlled substances in Portugal, so it is the body to approach if you need a position on your specific product before you travel.

The instrument most people encounter is the Schengen certificate. Germany's Federal Institute for Drugs and Medical Devices (BfArM) publishes a clear English explainer on travelling with narcotic drugs, which states that the Article 75 certificate is valid for a maximum of 30 days, that a separate certificate is needed for each controlled drug, that the treating physician completes it, and that the competent health authority must authenticate it before travel. For journeys outside the Schengen Area, BfArM describes a different document: a multilingual certificate giving the individual and daily dosage, the international name of the active substance and the duration of the journey, again authenticated by the health authority.

Two things follow. Flying into Portugal from the United States or the United Kingdom is not a Schengen-internal journey, so the certificate issued for Schengen travel is not the instrument in play; the certificate to ask your home authority about is the one for non-Schengen travel. And because the Schengen certificate is capped at 30 days, it does not solve an ongoing prescription. Verify the position for your medicine with INFARMED before you travel, and treat getting a Portuguese prescriber as the real answer.

Not for dispensing at a Portuguese pharmacy. This is the question behind most searches about transferring prescriptions to Portugal, and it has a clean answer.

Within the European Union there is a recognition mechanism. The European Commission's Your Europe portal explains on its page about prescriptions abroad, last checked 9 October 2025, that a prescription issued by a doctor in one EU country is recognised in the others when it carries the patient's full name and date of birth, the issue date, the prescriber's full name, professional qualification, direct contact details and work address including the country, and the medicine's common name rather than the brand, with format, quantity, strength and dosage. The same page states that dispensing is subject to the rules of the country where the prescription is presented, including time and dosage limits.

A prescription written in the United States sits outside that mechanism, and one written in the United Kingdom has been outside it since Brexit. There is also a structural reason a foreign paper prescription does not work in a Portuguese pharmacy: INFARMED's Normas relativas à prescrição de medicamentos e produtos de saúde, version 9.0 of 19 April 2024, state that prescribing must be done by electronic means using software certified by SPMS or through the PEM application, with the content validated by the central prescriptions system before issue. Your existing prescription is documentation for your new doctor, not something a pharmacy can act on.

Portuguese prescribing runs through a national electronic system, and the rules on validity and quantity are set out in the same INFARMED norms document, version 9.0 of 19 April 2024. Knowing the shape of it stops you booking appointments you do not need and running out of medicine you thought you had.

The long-duration line is the one that changes daily life. A single appointment can produce a year of authorisation while the pharmacy releases two months at a time, so a chronic prescription becomes a pharmacy errand rather than a repeated doctor's visit. That is worth asking your prescriber about explicitly, because whether a medicine counts as long-duration depends on its pharmacotherapeutic classification rather than on how long you personally have been taking it.

Medicines are not free in Portugal. UK government guidance on healthcare in Portugal, last updated 14 October 2021, states plainly that you will need to pay something towards the cost of any prescribed medicine. That page is several years old, so treat it as a directional statement rather than a current figure, and expect the pharmacy to tell you the actual amount.

The mechanism sits in the prescription itself. The INFARMED prescribing norms state that the prescription must record the entity responsible for paying or subsidising the medicine, and that the acronym SNS is entered whenever the patient is identified by a national user number with an active registration. In other words, the state contribution is triggered by your número de utente being live on the record, not by you being physically present in Portugal.

Annex 1 of the same document sets out how foreign citizens are handled. People insured by another EU or EEA member state or Switzerland are recorded using their European Health Insurance Card, provisional replacement certificate, S2 or S1 document. Citizens covered by international bilateral conventions are recorded from an entitlement certificate, and the document lists the conventions in force for Andorra, Brazil, Cape Verde, Quebec, Morocco and Tunisia. Neither the United States nor the United Kingdom appears in that bilateral list, which is a useful thing to know before you assume a reciprocal arrangement will carry you. For American and British arrivals the route to the state contribution runs through ordinary SNS registration as a resident, or through an S1 for those who hold one.

There is usually a gap between landing in Portugal and having a live SNS record with a family doctor attached, and private health cover is what carries the medical risk across it. For a household with an ongoing prescription, two parts of the policy are worth reading before you rely on them.

The first is outpatient prescription medicines. Private policies are built mainly around consultations, diagnostics and hospital treatment, and the cost of drugs collected from a pharmacy is frequently handled separately from the consultation that produced the prescription. Check whether outpatient pharmacy appears in the schedule of benefits at all, and what annual limit sits against it if it does.

The second is how pre-existing conditions are treated, because a condition you are already being treated for when a policy starts is handled differently from one that arises afterwards, and the medicines attached to it follow that treatment. Both are document questions with documented answers, so read the schedule of benefits and the exclusions rather than relying on a summary. Private cover also does something less obvious that is genuinely useful here: it gets you in front of a prescribing doctor quickly, which is exactly what you need in the first weeks when your imported supply is counting down.
