You started treatment somewhere else, it is working, and now you are relocating to Prague, Brno or anywhere else in Czechia. The obvious worry is a gap: weeks with no prescription, no doctor and no idea who to ask. It is worth planning for before you move rather than after.

The short version: your foreign prescription will very probably not work in a Czech pharmacy, bringing supplies helps only briefly, and the reliable route is an assessment by a Czech doctor who can issue a Czech eRecept. That assessment is genuinely an assessment, not a rubber stamp.

Why your foreign prescription probably will not work here

Czechia does participate in the EU cross-border e-prescription scheme, but the reality is narrower than the phrase suggests. According to the official ePrescription portal, dispensing a foreign e-prescription is optional for Czech pharmacies, so only those that opt in can do it, and the state maintains a list of participating "active pharmacies". At the time of writing the scheme covers a very limited set of countries, with others described as being added later.

So if you arrive from outside that small group, cross-border dispensing is simply not available to you, and even from a participating country you would still need a pharmacy that has opted in. A paper prescription from a foreign doctor is different again: the cross-border scheme covers electronic prescriptions only, and in practice Czech pharmacies are generally unable to dispense against a foreign paper form.

This is why a native Czech eRecept is the dependable option: once you have one, any pharmacy in the country can dispense it, with no list to check. Our guide to the Czech eRecept system explains how it works day to day, and what a pharmacy can and cannot accept.

One detail matters specifically for new arrivals. The eRecept identifies you by name and date of birth, so you do not need a Czech insurance number or a rodné číslo to receive one, as that guide sets out. What will not work yet is the pharmacy's shortcut of looking you up from an ID card, which the system offers only for patients already identified in it (ePrescription portal). Bring the prescription code itself, either the SMS or a printout.

Can you bring your own supply?

Bringing what you already have is sensible, and for a short overlap it is the simplest answer. Quantities for your own treatment, carried with you rather than shipped, are treated differently from bringing in medicines to supply anyone else. How much scrutiny that attracts depends on where you travel from: arriving from another EU country is ordinarily straightforward, while arriving from outside the EU means customs rules apply, so check the current allowances with Czech customs before you fly if you are carrying more than a couple of months of supply. Keep everything in original packaging with the pharmacy label and a copy of your prescription, and keep anything requiring refrigeration cold in transit, since a broken cold chain can degrade medicine even when the pack looks perfect.

What does not work is having medicine posted to you. Mail order of prescription medicines is illegal in the Czech Republic, from Czech and foreign pharmacies alike: under the Medicines Act (Act No. 378/2007 Sb.) distance selling by pharmacies covers over-the-counter products only (SÚKL on mail-order dispensing, in Czech). Any service offering to ship it to your Czech address is operating illegally, and our article on illegal online pharmacies covers what tends to arrive instead.

Treat your supply as a bridge of a few weeks, not a plan.

Why a Czech assessment is the reliable route

Rather than transferring a prescription, you restart care with a doctor who can prescribe here. Less disruptive than it sounds, particularly if you arrive with documentation.

A Czech doctor reviews your treatment history, what you currently take, how you have tolerated it, and your measurements, then decides how to proceed. Continuing the same treatment at the same dose is a common outcome when the records support it, but it is not automatic: the doctor may adjust the plan or decline treatment altogether. A doctor always makes the decision.

You do not need a registered Czech GP for this. That matters, because 554,000 people in Czechia have no registered GP and roughly 65% of them are foreign nationals. If you have no GP yet, obesity treatment without a Czech GP sets out the options. Consultations can be held in English, and treatment prescribed for obesity is self-pay for everyone here, Czech nationals included, so you pay what a Czech patient pays (Zdravotnický deník, March 2026, in Czech). Reimbursement attaches to an indication rather than to a molecule, so if you are treated for type 2 diabetes rather than for obesity the picture differs; Czech health insurance and weight-loss medication sets out which is which.

What to prepare before your consultation

The difference between a smooth continuation and a frustrating one is almost entirely documentation. Assemble this before you travel, while you still have easy access to your previous clinic:

A summary of your treatment history: when you started, which products, and why anything changed.
Your current dose and schedule, and when you last took it.
Recent laboratory results, plus any relevant imaging or specialist letters.
A list of all other medicines you take, including contraception and supplements.
Your medical history: diagnoses, allergies, previous surgery, and relevant family history.
Your own record: weight over time, side effects, and anything that did not agree with you.

Translations rarely need to be official, but documents in English are far easier to work with than ones in a language neither of you reads. A photograph of each page is better than nothing.

To get the process moving, you can complete the questionnaire and speak to a doctor online in English, at the same price Czech patients pay. If you want to check where you currently stand, our BMI calculator takes a moment.

Will you continue on the same dose?

Often, but not always.

If your treatment has been continuous and well tolerated, and your records confirm the dose, continuing at that dose is a reasonable clinical position. If there has been a gap, the picture changes. Tolerance to gastrointestinal effects fades once you stop, so restarting at a previously comfortable dose can bring back the nausea, vomiting, diarrhoea and constipation that are very common during dose increases, each affecting more than one in ten people (EMA: Wegovy). Doctors therefore often re-titrate upwards rather than resuming where you left off. That is a safety measure, not a setback.

The same conversation covers what rules treatment out or requires caution: pregnancy or plans to become pregnant, breastfeeding, a personal or family history of medullary thyroid carcinoma or MEN2 syndrome, previous pancreatitis, and gallbladder problems. The complete list of contraindications and warnings is in the summary of product characteristics, available via EMA and SÚKL. If any apply, the answer may differ from the one you had abroad.

Gaps matter for another reason. Weight commonly returns once treatment stops: in SURMOUNT-4, participants regained a substantial share of what they had lost after discontinuing.

A realistic timeline

Plan for weeks rather than days, and start before you land.

Before you move: request your records, note your dose, and ask your clinic for a written summary.
On arrival: book the consultation. No GP registration needed first.
The consultation: history, current treatment, measurements, and a decision on how to proceed. Sometimes the doctor asks for laboratory tests first, which adds time.
If treatment is appropriate: the eRecept is issued and you collect the medicine in person at any Czech pharmacy. Availability of specific products and doses varies, so call ahead, as our note on pharmacy availability explains.

Aim to begin about a month before your supply runs out. Arriving with none, start as soon as you have an address and a phone number.

Frequently asked questions

Can I continue Mounjaro treatment in the Czech Republic?

Treatment with the same product can continue if a Czech doctor assesses it as appropriate and it is available here. What does not carry over is your foreign prescription: you need a Czech eRecept, which means an assessment by a doctor licensed here, who may also adjust or decline treatment.

Will a Czech pharmacy accept my prescription from another country?

Usually not. Dispensing foreign e-prescriptions is optional for Czech pharmacies, only a limited list of participating pharmacies takes part, and the scheme currently covers very few countries (ePrescription portal). The scheme also covers electronic prescriptions only, so in practice a paper prescription from a foreign doctor is generally not something a Czech pharmacy can dispense against.

Can I bring my own supply when I move?

Quantities for your own treatment, carried with you in original packaging with a copy of your prescription, are treated differently from bringing in medicines to supply others, and arriving from another EU country is more straightforward than arriving from outside it, where customs allowances apply. Keep anything requiring refrigeration cold in transit. Having medicine posted to your Czech address is not an option, because mail order of prescription medicines is illegal here (SÚKL, in Czech); our article on illegal online pharmacies explains what tends to arrive instead.

Will I have to start again at the lowest dose?

Not necessarily. With continuous treatment and clear records, continuing at your current dose is normal. After an interruption, doctors commonly restart lower and build back up, because tolerance fades and side effects return. The decision rests with the doctor.

Do I need Czech insurance or a registered GP to be seen?

No. Registration with a GP is not mandatory here, and a telemedicine consultation does not require one. Treatment prescribed for obesity is self-pay for everyone in Czechia, Czech nationals included, so there is no difference in price between a local patient and a foreign resident (Zdravotnický deník, March 2026, in Czech). The reimbursement rules, including where they differ by indication, are in Czech health insurance and weight-loss medication.
