Diabetes in the United States: Insulin Costs, DEA Rules and Pharmacy Access

The US has no medication import cap for personal supply, but insulin costs without insurance can reach $300 per vial. Know what to carry and where to go.

Diabetes in the United States: what changes when you travel here

The United States has no upper quantity limit on personal medication imports, but it has the highest out-of-pocket insulin costs of any high-income country. The US healthcare system is largely private, and emergency departments are required by federal law to stabilise any patient regardless of insurance status, but non-emergency care carries significant cost exposure for uninsured travellers.[1][2][3]

This guide covers medication import rules, local brand names and availability, cold chain management across the country's varied climates, specialist access, emergency phrases, and the insurance declarations that matter most before you travel.

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

Key risks for diabetes travellers in the United States

Extreme out-of-pocket medication costs

Insulin and GLP-1 medications purchased without US insurance carry list prices that can exceed $300 (~€257) per vial or pen. Bring your full supply from home and carry a backup quantity wherever possible.

Climate extremes across a large geography

Summer temperatures in the US Southwest and Southeast regularly exceed 38°C (100°F), which can degrade insulin stored outside a cold chain within hours. Plan storage carefully for any travel to desert states such as Arizona, Nevada, or Texas.

No reciprocal public health coverage

The United States has no reciprocal public healthcare agreement with any other country. All non-emergency care must be paid for out-of-pocket or through private travel insurance. Comprehensive travel insurance is essential before departure.[2]

Brand name and formulation differences

US pharmacies stock insulin formulations and GLP-1 brands that may differ from what you use at home. Carry your INN-labelled prescription to avoid confusion, and bring enough supply to avoid needing a local refill.[1][3]

Time zone changes across multiple zones

The continental US spans four time zones, and the Pacific and Mountain zones shift medication timing for travellers from distant regions. Discuss a dose-timing adjustment plan with your specialist before departure.

Preparation checklist

  • Book a pre-travel appointment with your endocrinologist — Discuss time zone adjustments and confirm your insulin or GLP-1 regimen is stable before departure.
  • Get a specialist letter on headed paper — State your diagnosis, all medications by INN and brand name, and confirm that injectable devices and needles are medically necessary.
  • Carry prescriptions with INN names — US pharmacists use brand names; having the INN prevents substitution errors if you need emergency assistance.
  • Check CGM and insulin pump device compatibility — US devices may use different frequencies or app ecosystems; confirm before departure with your device manufacturer.
  • Obtain comprehensive travel insurance with diabetes cover — Declare all associated conditions; emergency hospitalisation in the US can exceed $10,000 (~€8,573) per day.
  • Download your Nomedic IPS before you fly — Your International Patient Summary is accessible offline and shareable via QR code at any US emergency department.
  • Carry your full supply of insulin or GLP-1 medication — Bring enough for your trip plus a 10-day buffer; US list prices without insurance are prohibitively high.
  • Pack a validated insulin cooler or fridge pack — Essential for travel to desert states (Arizona, Nevada, Texas, California) where summer temperatures exceed 38°C.
  • Identify an endocrinologist at your destination — Use Nomedic's provider search or the American Diabetes Association's online directory.
  • Save emergency numbers offline — 911 covers ambulance, police, and fire across all US states. Save in Nomedic.

Documents to carry

Documents to carry when travelling to the United States with diabetes

US airport security (TSA) and emergency departments work fastest when you can present your documentation digitally and offline. The Nomedic app keeps all critical records in one place.

Your International Patient Summary (IPS)

Your Nomedic IPS contains your diabetes diagnosis, current medications with INNs, allergies, device list, and emergency contact, all in a format readable by any US clinician.

At a US emergency department, showing your IPS QR code on arrival removes the need to explain your history verbally. TSA officers are familiar with medical device declarations; your IPS confirms the clinical necessity of insulin, needles, and pumps in your carry-on.

Medications advice

Bringing your diabetes medications to the United States

The FDA imposes no upper quantity limit on personal medication imports for travellers carrying a reasonable personal supply. CBP (US Customs and Border Protection) guidance recommends keeping medications in their original, labelled containers and carrying a copy of the prescription or a letter from your prescriber. None of the diabetes medications listed below are controlled substances under the DEA scheduling system, so no import permit is required.[1]

Do not post your medication to the United States.

Mailing prescription medications into the US without FDA approval is prohibited under federal law. Always carry your supply in person in your hand luggage.

Diabetes medications: brand names, INNs, and US availability

The table below lists common diabetes medications, their FDA-approved US brand names, and any travel-relevant storage notes.

INN (Generic Name)Brand Name(s)
insulin lispro
Admelog, Humalog, Lyumjev

Store at 2-8°C until opening; in-use pens stable at room temperature below 30°C for 28 days.

insulin aspart
NovoLog, Fiasp

In-use pens stable at room temperature below 30°C for 28 days; avoid exposure to heat or light.

insulin glargine
Lantus, Basaglar, Toujeo

In-use pens stable at room temperature below 30°C for 28 days (Lantus/Basaglar) or 42 days (Toujeo).

semaglutide
Ozempic, Wegovy, Rybelsus

Refrigerate at 2-8°C until first use; in-use pens stable at room temperature below 30°C for 56 days.

metformin
Glucophage, Fortamet, Glumetza

No cold-chain requirement; store below 25°C.

empagliflozin
Jardiance

No cold-chain requirement; store below 30°C.

sitagliptin
Januvia

No cold-chain requirement; store below 25°C.

Carbonic anhydrase inhibitors and metformin or SGLT2 inhibitors

The FDA prescribing information for metformin and empagliflozin both note clinically significant interactions with carbonic anhydrase inhibitors such as topiramate and acetazolamide, which are sometimes used as altitude sickness prophylaxis. If you plan to use either for high-altitude travel within the US (e.g. Colorado Rockies), discuss the combination with your prescriber before departure.

Travelling with injectable therapies

If you use injectable insulin or a GLP-1 medication, these steps apply regardless of which US state or airport you are passing through.

1
1. Carry in hand luggage only. TSA allows medically necessary liquids including insulin in carry-on bags in quantities exceeding the standard 100 ml limit; declare them separately at the checkpoint.[4]
2
2. Declare at security. Tell the TSA officer before the bin goes through the X-ray. Insulin pens, syringes, lancets, and glucose monitors may be inspected visually; your specialist letter confirms their medical necessity.
3
3. Maintain the cold chain. FDA-approved insulin lispro (Humalog) product labelling states in-use vials must not exceed 30°C for longer than 28 days.[5] Use a validated insulin travel wallet or cooling case for any journey over two hours in warm conditions. For more advice on cold-chain management, see our guide for travelling with insulin.
4
4. Book direct flights where possible. Checked baggage holds can reach sub-zero temperatures on long-haul sectors, and connections increase the risk of insulin being exposed to temperature extremes.

Healthcare and prescriptions in the United States

The US healthcare system is predominantly private and insurance-based. Under the Emergency Medical Treatment and Labor Act (EMTALA), all hospital emergency departments must provide stabilising treatment regardless of insurance status, but billing follows after treatment. Without travel insurance, an ER visit for a diabetes-related emergency can cost $3,000 to $25,000 (~€2,572 to ~€21,433). [2]

A private endocrinologist appointment at an outpatient clinic costs $200 to $400 (~€171 to ~€343) depending on state and clinic type. Foreign prescriptions are not dispensed at US pharmacies; a US prescriber or urgent care physician must issue a local script for any refill.[2]

Insulin is a prescription-only medication in most US states, though Texas, California, and several others permit limited OTC sale of certain human insulin formulations (such as Novo Nordisk's ReliOn brand) at large pharmacy chains. GLP-1 medications such as semaglutide and liraglutide require a US prescription for any in-country supply. None of the standard diabetes medications are controlled substances under DEA scheduling.

GLP-1 medications require a US prescription for refills

Ozempic, Wegovy, and similar GLP-1 pens are not available OTC and cannot be dispensed on a foreign prescription. If you need an emergency supply, visit an urgent care clinic or telehealth service to obtain a US script before going to the pharmacy.

Finding a diabetes specialist

Endocrinologists (the specialist term used in the US) work in outpatient clinics, hospital-based endocrinology departments, and university medical centres. The American Diabetes Association's provider directory at diabetes.org allows searching by location and specialty. Nomedic's United States travel guide and dedicated city guides also list healthcare and specialist options.

Walk-in appointments are generally not available for specialist care; most clinics require booking 2 to 4 weeks in advance. For urgent non-emergency needs, urgent care clinics and telehealth platforms such as Teladoc or MDLive can issue a US prescription within hours. Identify your nearest endocrinology department before departure and save the details offline.

Search for providers near your destination

Use Nomedic's provider search to find diabetes specialists in the United States. Save the address and phone number offline before you travel.

Find a specialist

If your cold chain breaks in the United States

Insulin exposed to heat does not always need to be discarded immediately. Product labelling defines excursion windows; check your specific brand's prescribing information or the manufacturer's patient guide before deciding.

1
1. Immediate local action. Ask your hotel front desk for refrigerator access or request a medical refrigerator from the concierge. Any major US pharmacy chain (CVS, Walgreens, Rite Aid) can store refrigerated medications briefly if you explain the situation.
2
2. Contact your home specialist. Send a photo of the affected vial or pen and the duration of excursion so they can confirm whether the dose is still viable.
3
3. Local replacement if needed. A US urgent care clinic or telehealth service can issue a local prescription for replacement insulin. Bring your Nomedic IPS and specialist letter. Expect to pay $100 to $300 (~€86 to ~€257) per vial without insurance at a retail pharmacy, or ask the pharmacist about manufacturer savings programmes such as Eli Lilly's Insulin Value Programme.[6]

Managing heat and time zone shifts day to day in the United States

Summer temperatures in the US Southwest and Southeast exceed 38°C (100°F) for extended periods, and Phoenix, Arizona recorded temperatures above 43°C on multiple days in July 2023. The continental US also spans four time zones, which affects meal timing and dose schedules for travellers arriving from distant regions.

Keep insulin and GLP-1 pens in an insulated cooler bag whenever you are outdoors in warm states; do not leave them in a car glove box or direct sunlight. Most large US shopping malls, grocery stores, and hotel lobbies are air-conditioned to 18 to 22°C year-round, providing reliable refuge if temperatures spike.

For time zone adjustment, shift meal times by 30 minutes per day in the direction of travel, and discuss the approach with your endocrinologist before you leave. US restaurants accommodate meal-timing requests; many diners and 24-hour chains allow eating at non-standard hours without difficulty.

Heat-related glucose changes are not always an equipment failure

Unexplained high readings in hot conditions may reflect insulin degradation rather than a dosing problem. Check your pen for cloudiness or discolouration before assuming the reading is accurate. If readings remain elevated and the pen appears compromised, follow the guidance in the Emergency tab.

English phrases for clinicians

Show your Nomedic IPS first, it removes the need to explain your diagnosis verbally. If verbal communication is needed:

“”

I have diabetes.

“”

I am having a hypoglycaemic episode and need glucose immediately.

“”

I need to see an endocrinologist.

“”

I take insulin. My last dose was at [time].

“”

Where is the nearest emergency department?

“”

I need an emergency supply of insulin. My brand is [name].

Insurance considerations

What to know about travel insurance

Standard policies often exclude pre-existing diabetes

Many travel insurance policies exclude pre-existing conditions by default or cap diabetes-related claims. Emergency hospitalisation costs in the US can reach $10,000 (~€8,573) per day without coverage, making comprehensive, condition-inclusive insurance non-negotiable.

What to look for in a policy

Diabetes explicitly named as covered

Not just 'pre-existing conditions covered'. Your condition should be named on the schedule.

Emergency medical evacuation

Covers repatriation to your home country if local care is insufficient or unaffordable.

Replacement medication cover

Covers emergency replacement if your insulin or other medication is lost, damaged, or delayed.

24-hour assistance line with translator access

So someone can communicate with US 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.

1
Diabetes type and duration

Type 1, Type 2, LADA, or MODY; how long you have been diagnosed. Both affect underwriting.

2
Current medication and dose

Use the INN alongside the brand name.

3
Last HbA1c result and date

Insurers assess control level; a recent out-of-range result may affect premiums or exclusions.

4
Associated conditions

Declare neuropathy, retinopathy, nephropathy, cardiovascular disease, or hypertension if present.

Store your insurance details in Nomedic.

Go to profile.
EU and EEA travellers

The EHIC and GHIC are not valid in the United States. The US has no reciprocal healthcare agreement with EU or EEA countries. EHIC holders travelling to the US must rely entirely on private travel insurance. This is a critical gap to address before departure.

Emergency protocol

Going to a US emergency department

Diabetic ketoacidosis (DKA) and severe hypoglycaemia are medical emergencies. Call 911 immediately if you or a companion cannot manage the episode with available supplies. Contact your travel insurer's emergency line as soon as you are safe; they can coordinate direct billing with the hospital and advise on repatriation if needed.

When you arrive, follow in order

1
Show your Nomedic IPS immediately.

Full clinical picture in seconds, no verbal explanation needed.

2
Say this phrase.

Hand your phone to the triage nurse:

I have diabetes. I may be in diabetic ketoacidosis or have severe low blood sugar. I need urgent assessment.

3
Hand over your specialist letter.

It lists your current medications, doses, and known complications, reducing the risk of incorrect treatment.

4
Tell the clinician your last dose and timing.

Exact timing of your last insulin dose or GLP-1 injection is critical diagnostic information in a DKA or hypoglycaemia workup.

Calls and location

Call 911 for ambulance, police, or fire anywhere in the US. If you are in a hotel, the front desk can call on your behalf. Your location address is shown in your hotel key card holder or in most ride-share apps.

In hospital

Wound healing and infection risk

Peripheral neuropathy and reduced circulation increase the risk of wound complications. Tell the treating clinician you have diabetes before any wound is dressed, as this affects both treatment choice and follow-up requirements.

After any emergency

Contact your home specialist as soon as you are stable

Before you leave the hospital if possible.

Keep the discharge summary

Required for insurer reimbursement and continuity of care with your home endocrinologist.

Frequently asked questions

Is it legal to bring insulin and GLP-1 medications into the United States?

Personal-use quantities of insulin and GLP-1 medications (such as semaglutide/Ozempic or tirzepatide/Mounjaro) are generally permitted to enter the United States under the FDA's personal importation policy, provided the supply does not exceed approximately 90 days and is accompanied by a valid prescription or a letter from your treating physician. Medications must be in their original, labelled containers and are subject to inspection by US Customs and Border Protection (CBP). The DEA classifies insulin as a non-controlled substance, so no additional DEA permit is required for import. GLP-1 agents are likewise not DEA-controlled. If CBP or FDA officers have concerns about a medication's legitimacy or quantity, they may detain or seize it, so carrying supporting documentation is strongly advised.

Do I need to declare insulin at US customs?

Insulin does not need to be declared on the standard CBP customs form, but TSA requires you to disclose it verbally at the security checkpoint. Keep insulin in its original labelled container and carry a prescription or specialist letter. There is no quantity cap for a personal supply.

Can I buy insulin over the counter in the United States?

A limited range of human insulin (regular and NPH formulations, sold as ReliOn at Walmart) is available OTC in most US states without a prescription at a lower price point. Analogue insulins (lispro, aspart, glargine) and all GLP-1 medications require a US prescription. If you need an analogue refill, visit an urgent care clinic or telehealth service to obtain a local script.

How much does insulin cost in the United States without insurance?

Analogue insulin vials cost $100 to $300 (~€86 to ~€257) at retail pharmacies without insurance. GLP-1 pens such as Ozempic can exceed $900 (~€771) per month at list price. Manufacturer savings programmes (Eli Lilly, Novo Nordisk, Sanofi) can reduce costs for uninsured patients. Bring your full supply from home to avoid these costs entirely.

Is Ozempic available in US pharmacies without insurance?

Ozempic (semaglutide) is available at US pharmacies with a valid US prescription, but the list price without insurance exceeds $900 (~€771) per pen pack. A foreign prescription cannot be used; a US prescriber must issue the script. Novo Nordisk offers a patient assistance programme for uninsured patients who qualify by income. Bring your full supply from home to avoid this cost.

Can I use a CGM or insulin pump on US domestic flights?

TSA permits continuous glucose monitors and insulin pumps through security checkpoints. You can request a manual pat-down instead of an X-ray scanner if your device manufacturer recommends avoiding X-ray exposure. Carry the device manual and your specialist letter as supporting documentation. Both devices may remain on your body during flight.

Do I need special travel insurance to visit the United States with diabetes?

Comprehensive travel insurance with diabetes explicitly covered is essential for any trip to the US. The country has no reciprocal public healthcare agreement with any other country, and emergency hospitalisation can exceed $10,000 (~€8,573) per day. Standard policies often exclude pre-existing conditions by default.

Declare thoroughly

Declare your diabetes type, duration, current medications, last HbA1c, and any associated conditions. Incomplete disclosure invalidates the entire policy, not just the diabetes-related claim.

What are the emergency numbers in the United States?
