Diabetes in Greece: Insulin Storage, Heat Risk and Pharmacy Access
Greece's summer heat threatens insulin storage and pharmacies require local prescriptions. Know the rules before you fly.
Diabetes in Greece: what changes when you travel
Greece's summer temperatures regularly exceed 38°C in inland regions, posing a serious cold-chain risk for insulin and GLP-1 therapies. Greek pharmacies require a local prescription to dispense most diabetes medications, and EU cross-border prescriptions are not consistently honoured at the pharmacy counter.
This guide covers import rules, cold-chain planning, local brand names, specialist access through the Greek national health system (ESY), and what to do if your supply is lost or damaged. It also includes emergency phrases in Greek and the key documents to carry.

Key risks for diabetes travellers in Greece
Insulin degradation in summer heat
Ambient temperatures in Athens and the Aegean islands regularly exceed 38°C from June through August, which degrades unrefrigerated insulin rapidly. Carry a medical-grade cooling wallet and identify refrigeration at your accommodation before you arrive.[1]
Prescription acceptance at Greek pharmacies
Greek pharmacies (φαρμακεία) require a Greek prescription for most diabetes medications. A foreign prescription is not sufficient to obtain a refill; you must either bring your full supply or consult a local physician.
GLP-1 cold-chain disruption on island travel
Ferry crossings between Greek islands can last several hours in direct sun with no reliable refrigeration on board. Plan cold-chain logistics for any island leg of your trip, not just the flight.
Dehydration and blood glucose variability
Heat and physical activity on uneven terrain (cobblestone streets, hillside towns) increase the risk of dehydration, which can cause blood glucose to shift unpredictably. Carry glucose tablets and monitor more frequently during outdoor sightseeing in peak summer.
Limited specialist availability on smaller islands
Smaller Greek islands have limited or no endocrinology services. A medical evacuation to Athens or Thessaloniki may be necessary for serious supply failures or hypoglycaemic episodes requiring specialist input.
Preparation checklist
- See your endocrinologist 4-6 weeks before travel — Get a letter confirming your diagnosis, current medications (with INNs), and any devices. Request it on headed paper with a stamp.
- Confirm refrigeration at every accommodation — Hotels and rental properties vary. Contact each property in advance and ask specifically about a locked mini-fridge.
- Check your CGM or pump device compatibility — Ensure any wireless-enabled device is set to local frequency bands and bring a spare battery or charger.
- Download the Nomedic app and complete your IPS — Your International Patient Summary stores diagnosis, medications, allergies, and emergency contacts, readable offline and shareable via QR code.
- Bring a full supply for your trip plus at least 10 extra days — Greek pharmacies cannot fill foreign prescriptions, so your home supply is your primary resource.
- Pack all insulin and GLP-1 therapies in a medical-grade cooling wallet — Check the wallet's rated hours and test it before you leave.
- Carry glucose tablets in every bag — Keep a supply in your day bag, beach bag, and at your accommodation.
- Divide your supply between hand luggage and a travel companion — Never check injectable therapies into hold baggage; temperature in aircraft holds is uncontrolled.
- Research the nearest hospital with an endocrinology department at each destination — Athens and Thessaloniki have specialist units; smaller islands do not.
- Save emergency numbers offline — Ambulance 166, Police 100, Pan-European 112. Store in Nomedic and in your phone's contacts.
Documents to carry when travelling to Greece with diabetes
Greek clinicians and pharmacists will ask for documentation when you seek care or attempt to obtain medication. Keep the following accessible in the Nomedic app and in printed form.
Your International Patient Summary (IPS)
The IPS is a structured medical record that communicates your diagnosis, active medications, allergies, and emergency contacts to any clinician worldwide, in a format they can read without needing to contact your home provider.
Nomedic generates your IPS to the HL7 FHIR R4 standard. It is stored offline on your device and can be shared via QR code at a Greek emergency department or pharmacy counter.

Bringing your diabetes medications to Greece
Greece, as an EU member state, follows EU rules on personal medication imports. Diabetes medications are permitted when accompanied by a prescription or medical certificate. For stays over 90 days, additional documentation from your home physician is advisable. Insulin and GLP-1 therapies require original packaging showing the INN and your name.[2]
Do not post your medication to Greece.
Posting prescription medication internationally is prohibited under Greek customs law. Always carry insulin, GLP-1 therapies, and all other diabetes medications in your hand luggage.
Diabetes medications: brand names, INNs, and Greece availability
The following medications are approved and available in Greece under EMA marketing authorisations; local brand names may differ from those you use at home.[3]
Not a cold-chain medication. Available in most Greek pharmacies with a local prescription.
Requires refrigeration at 2-8°C until first use. In-use pen stable up to 28 days at room temperature below 30°C.
Requires refrigeration at 2-8°C until first use. In-use pen stable up to 28 days below 30°C.
Requires refrigeration at 2-8°C. In-use Ozempic pen stable up to 56 days below 30°C. Supply can be constrained; bring full trip supply.
Oral tablet. No cold-chain requirement. Available in Greek pharmacies with local prescription.
Monitor hydration carefully in Greek summer heat. Increased risk of urinary tract infection.
Available in Greece. No cold-chain requirement.
SGLT2 inhibitors and summer heat: dehydration risk
Empagliflozin and other SGLT2 inhibitors promote urinary glucose excretion, which increases urine output and dehydration risk. In Greek summer temperatures above 35°C, this effect compounds the dehydrating impact of heat. Ensure consistent fluid intake throughout the day and monitor for signs of volume depletion. Consult your prescriber about heat-specific management before you travel.
Travelling with injectable therapies
If you use insulin pens, syringes, or GLP-1 auto-injectors, these steps apply on every leg of your journey to Greece.
Read our dedicated guides for flying with insulin and flying with GLP-1 medications for more practical advice on cold-chain management.

Healthcare and prescriptions in Greece
Greece operates a national health system called ESY (Εθνικό Σύστημα Υγείας). EU and EEA citizens holding an EHIC or GHIC can access state-funded care at ESY hospitals and health centres on the same terms as Greek nationals. Travellers without EHIC access should use private clinics; an endocrinologist (ενδοκρινολόγος) consultation at a private clinic in Athens costs approximately €80-€120 (~$93-$140). Foreign prescriptions are not accepted at Greek pharmacies for dispensing; you must obtain a local prescription from a Greek physician to access any refill.[5]
Insulin and GLP-1 therapies are prescription-only in Greece and are dispensed from retail pharmacies (φαρμακεία) with a valid Greek prescription. Metformin and other oral diabetes medications are similarly prescription-only. No diabetes medication is available over the counter. If you are an EHIC holder, a prescription issued through an ESY consultation is valid at state pharmacies.
Insulin is dispensed from retail pharmacies, not hospitals
For an emergency insulin supply, visit any pharmacy (φαρμακείο) with your specialist letter and IPS. The pharmacist will direct you to a nearby physician for a Greek prescription if needed. Bring both documents to avoid delays.
Finding a diabetes specialist
Endocrinologists (ενδοκρινολόγοι) work in the internal medicine departments of public ESY hospitals and in private medical centres. Major hospitals in Athens, including Laiko General Hospital and Evangelismos, have endocrinology departments. Thessaloniki's AHEPA University Hospital also has a specialist unit.
On islands, endocrinology services are concentrated in the island's main town, if available at all. Book a private appointment in advance for non-emergency consultations; walk-in slots at private clinics are not guaranteed. Identify the nearest endocrinologist and save their contact details offline before you travel.
Search for providers near your destination
Use Nomedic's provider search to find diabetes specialists in Greece. Save the address and phone number offline before you travel.
If your cold chain breaks in Greece
An insulin pen left in a hot car or on a beach for a short period may still be usable. Product-specific temperature excursion windows vary by formulation; check the product leaflet for your specific insulin or GLP-1 pen before assuming it is damaged. Do not use insulin that has been frozen, appears cloudy (for clear formulations), or has visible particles.[4]
Managing heat and glucose control day to day in Greece
Athens records a mean July maximum of approximately 33°C, with heat waves pushing temperatures above 40°C. Combined with physical activity on uneven cobblestone terrain and the Greek habit of dining late (typically 9 pm to 11 pm), these conditions create meaningful variability in glucose levels.[6]
Schedule outdoor sightseeing before 10 am or after 5 pm to avoid peak heat. Most Greek museums, churches, and shopping centres are air-conditioned and can serve as midday rest points. Greek supermarkets (σούπερ μάρκετ) sell bottled water widely; aim for at least 2-3 litres daily in summer.
The late dinner culture means your evening meal may fall 3-4 hours later than your home schedule. If you use a fixed-dose regimen, discuss timing adjustments with your endocrinologist before you travel. Carry fast-acting glucose in every bag, including your beach bag.
Heat-related glucose shifts are not always a medication failure
Sustained high temperatures can cause glucose to drop more quickly than usual, even without a change in medication or food intake. If you experience an unexpected low after outdoor activity in the heat, treat it as you normally would and monitor more frequently for the next two hours. If repeated lows occur without a clear dietary cause, seek review from a local physician.
Greek phrases for clinicians
Show your Nomedic IPS first. It removes the need to explain your diagnosis verbally. If verbal communication is needed:
“Έχω διαβήτη.”
I have diabetes.
“Έχω υπογλυκαιμία.”
I am having a hypoglycaemic episode.
“Χρειάζομαι ενδοκρινολόγο.”
I need an endocrinologist.
“Παίρνω ινσουλίνη για τον διαβήτη μου.”
I take insulin for my diabetes.
“Πού είναι το πλησιέστερο νοσοκομείο με ενδοκρινολογικό τμήμα;”
Where is the nearest hospital with an endocrinology department?
“Χρειάζομαι επείγουσα παροχή ινσουλίνης.”
I need an emergency supply of insulin.
Insurance considerations
What to know about travel insurance
Many standard travel policies exclude diabetes-related claims unless the condition is explicitly declared and accepted at underwriting. Emergency diabetes care in Greece, including hospitalisation and specialist consultation, can cost €1,500 or more (~$1,750) without insurance.
What to look for in a policy
Not just 'pre-existing conditions covered'. Your condition should be named on the schedule.
Covers transfer from a smaller island to a mainland hospital if local care is insufficient.
Covers emergency replacement if your insulin or devices are lost, damaged, or stolen.
So someone can communicate with Greek clinicians on your behalf in an emergency.
What to declare at application
Declare thoroughly. Incomplete disclosure can invalidate your entire policy, not just the diabetes-related claim.
State whether Type 1 or Type 2 and how long you have been diagnosed.
Use the INN alongside the brand name.
Many insurers use recent HbA1c to assess current control and set terms.
Include any cardiovascular disease, nephropathy, neuropathy, or retinopathy.
Your policy number and emergency assistance line, saved alongside your IPS and accessible offline.
An EHIC or GHIC gives EU and EEA citizens access to state-provided healthcare at Greek ESY facilities on the same terms as Greek nationals. This covers emergency consultations but does not cover private clinics, medical evacuation, or the cost of replacing lost medication. Travel insurance remains essential alongside your card.
Emergency protocol
When to go to the emergency department
A severe hypoglycaemic episode requiring assistance from another person, or one that does not resolve with oral glucose within 15 minutes, requires immediate emergency care. Contact your travel insurer's 24-hour line before or immediately after calling for an ambulance, as pre-authorisation may be required for hospital admission.
When you arrive, follow in order
Full clinical picture in seconds, no verbal explanation needed.
Hand your phone to the triage nurse:
Έχω διαβήτη και υπογλυκαιμία. Χρειάζομαι γλυκόζη ή γλυκαγόνη.
I have diabetes and low blood sugar. I need glucose or glucagon.
Hand the triage team your specialist letter or open your Nomedic IPS medications tab so they can see all active drugs and doses.
Your Nomedic IPS lists all known allergies; point the clinician to the allergies section if you cannot communicate verbally.
Calls and location
Call 166 for an ambulance in Greece or 112 for the pan-European emergency line. If you are on an island, tell the dispatcher your location and the island name as ferry or helicopter evacuation may be required. Police: 100.
In hospital
Peripheral neuropathy or vascular complications can affect wound healing. Tell the treating clinician about your diabetes so they can assess wound closure, antibiotic need, and post-discharge monitoring before you leave the hospital.
After any emergency
Before you leave the hospital if possible.
Required for insurer reimbursement and continuity of care.

Frequently asked questions
Is insulin legal to bring into Greece?
Insulin is legal to bring into Greece. As an EU member state, Greece permits travellers to carry a personal supply of prescription medication for the duration of their trip, provided it is accompanied by a prescription or medical certificate and kept in original packaging.
Can I buy insulin at a Greek pharmacy without a local prescription?
No. Insulin is prescription-only in Greece and pharmacies require a Greek prescription to dispense it. A foreign prescription alone is not accepted at the pharmacy counter. If you need a supply, visit a private clinic or ESY hospital to obtain a local prescription, then collect from any pharmacy.
Bring your full supply from home
Do not rely on being able to obtain a refill in Greece, particularly on smaller islands where pharmacy stock is limited.
Is Ozempic (semaglutide) available in Greek pharmacies?
Ozempic (semaglutide) is EMA-approved and marketed in Greece, but stock can be constrained due to global supply pressures. Bring your full trip supply plus a buffer. If you need an emergency replacement, a local physician can issue a prescription, but availability at a specific pharmacy is not guaranteed.
How can I communicate my diabetes diagnosis in an emergency in Greece?
Show your Nomedic IPS first. If verbal communication is needed:
“Έχω διαβήτη.”
I have diabetes.
“Παίρνω ινσουλίνη για τον διαβήτη μου.”
I take insulin for my diabetes.
How long can I leave an insulin pen unrefrigerated in Greece's summer heat?
Tolerance windows vary by formulation. Most in-use insulin pens are stable for 28-31 days at room temperature below 25-30°C, depending on the product. In Greece's summer, outdoor ambient temperatures regularly exceed this threshold. Check your specific product leaflet for the rated excursion window and use an insulated cooling wallet during any period outdoors.
Never use frozen insulin
Insulin that has been frozen is degraded regardless of how briefly. Discard it and obtain a replacement.
Do I need special travel insurance to visit Greece with diabetes?
Standard travel policies frequently exclude pre-existing diabetes unless it is declared and explicitly accepted. An EHIC or GHIC card covers emergency state-funded care for EU and EEA citizens but does not cover private clinics, medical evacuation, or replacement medication. A specialist travel insurance policy that names diabetes explicitly is essential regardless of whether you hold an EHIC.
Declare thoroughly
Subtype, current medication, last HbA1c result, and any associated conditions. Incomplete disclosure invalidates the entire policy.
