How to Manage Medication Refills During Extended Travel

Running out of medication while you’re halfway across the world isn’t just inconvenient-it can be dangerous. Whether you’re on a three-month backpacking trip through Southeast Asia or a six-week business tour across Europe, missing a single dose of your blood pressure pill, thyroid med, or insulin can send your health into a tailspin. The good news? With the right plan, you can avoid this entirely. Most people don’t realize how much control they actually have over their meds while traveling-until they’re stuck in a foreign pharmacy with no prescription and no backup.

Start Planning 30 Days Before You Leave

The biggest mistake travelers make? Waiting until the last week to think about meds. You need time. Time to talk to your doctor. Time to coordinate with your pharmacy. Time to deal with insurance red tape. Start 30 days out. That’s not optional-it’s the standard recommendation from the CDC and major pharmacy chains like CVS and Walgreens.

Call your pharmacy and ask for a vacation override. That’s the term insurers use when they let you get an early refill because you’re traveling. Most major U.S. insurers-including UnitedHealthcare, Aetna, and Blue Cross Blue Shield-allow this. But policies vary. UnitedHealthcare typically lets you refill 7 days early. Blue Cross Blue Shield of Michigan allows up to 14. Ask for the exact rules for your plan. Don’t assume. Don’t guess. Write it down.

Get a 90-Day Supply If You Can

If your doctor approves, ask for a 90-day supply instead of 30. It’s not always possible-especially with controlled substances-but for most chronic conditions like diabetes, hypertension, or asthma, it’s a game-changer. A 2021 Kaiser Permanente study of 45,000 travelers showed that switching to 90-day supplies cut refill requests by 67%. Fewer refills mean fewer chances for something to go wrong.

Pharmacies are required to honor this if your insurance allows it. Most do. And if your doctor says no? Ask why. Sometimes it’s just habit. Sometimes it’s outdated policy. Push back. Bring up the CDC’s travel guidelines. Say you’re planning an extended trip. You’d be surprised how often they’ll say yes.

Know the Rules for Controlled Substances

If you’re on opioids, benzodiazepines, stimulants, or other Schedule II-IV drugs, things get complicated. Forty-eight U.S. states enforce a “28-day rule”: you can’t refill a 30-day prescription until 28 days have passed. That means if your trip lasts longer than 28 days, you need to plan ahead. You can’t just walk into a pharmacy abroad and get a refill. You can’t even get one in the U.S. without your doctor’s explicit approval.

Here’s what works: Get a 90-day supply before you leave. Get a signed letter from your doctor on letterhead explaining your diagnosis, dosage, and why you need the medication. Some countries, like Japan and Thailand, require this even for non-controlled meds. For controlled substances, it’s non-negotiable. Also, carry your original prescription bottle with the pharmacy label. It’s your proof of legitimacy.

Double Your Meds-And Separate Them

Dr. Jennifer Schaefer from the American Pharmacists Association says this plainly: “Take your medication in two separate containers that you keep in two separate places.” That’s not just good advice-it’s survival protocol.

Put half your meds in your carry-on. Put the other half in your checked luggage. Why? Because if your bag gets lost, you still have meds. If you’re stopped at security, you can declare your liquids without panic. TSA allows medically necessary liquids over 3.4 ounces if you tell them at the checkpoint. Ninety-eight percent of U.S. airports follow this rule. But don’t assume every international airport does. Know the rules of your destination.

Don’t put all your pills in one pill organizer. Use two different ones. Or better yet, keep some in original bottles. Original bottles have the pharmacy name, your name, and the prescription number. That’s your golden ticket if you need to explain your meds to a foreign pharmacist or customs officer.

International Travel? Check Embassy Rules First

This is where most travelers get caught off guard. Just because your meds are legal in the U.S. doesn’t mean they’re legal in Thailand, Dubai, or Germany. Seventy-eight countries require written documentation to bring prescription meds. Sixty-three have strict quantity limits. For example: Thailand caps opioid prescriptions at 30 days, even if your doctor wrote 90. The UAE bans even common antidepressants like fluoxetine without special permits.

Go to the embassy website of every country you’ll visit-including layovers. Look for “medication import guidelines.” Download and print them. If you can’t find it, email the embassy. Ask: “What documentation is required for [medication name] to enter your country?”

Bring:

• Original prescription bottles with labels
• Doctor’s letter on letterhead (signed and dated)
• Notarized copy of your prescription
• Copy of your insurance card

Some countries, like Canada and the UK, recognize U.S. prescriptions. Others, like Australia and Singapore, require you to apply for a permit in advance. Don’t wait until you land to find out you can’t bring your meds.

Time Zones and Scheduling: Don’t Guess

Skipping a dose because you’re confused about time zones is a common mistake. If you take your pill at 8 a.m. Eastern Time, don’t suddenly switch to 8 a.m. local time when you land in Tokyo. Your body’s rhythm is still on home time. The American Academy of Sleep Medicine recommends sticking to your home schedule for the first 24 to 48 hours after arrival. Then, gradually shift to local time.

Use your phone’s medication reminder app. Set it to your home time zone. Or use a second device. Write down your schedule on paper. Don’t rely on memory. Even a 3-hour shift can throw off meds like insulin or seizure drugs. When in doubt, take it at your home time. Better safe than sorry.

What If You Lose Your Meds?

You’re not alone. The 2023 GoodRx Survey found that 41% of travelers forgot or lost their meds. Here’s what to do:

Domestically: Walk into any CVS, Walgreens, or Rite Aid. Show your original bottle or prescription. Ask for a 3-day emergency refill. Ninety-four percent of national chains will give you one. Some even let you use their MinuteClinic for a one-time renewal-up to two times a year. CVS says 79% of users who used this service called it “lifesaving.”

Internationally: If you’re abroad and out of meds, your first call should be to your country’s embassy. They often have lists of local pharmacies that work with expats. If you have travel insurance, call their 24/7 helpline. Many now offer telehealth prescriptions. Teladoc handled over 1.2 million emergency refills in 2022. You can get a new prescription emailed to a local pharmacy in many countries.

If all else fails, try a hospital emergency room. Bring your doctor’s letter and original bottle. Many ERs can provide a short-term supply while you figure out the next step.

Keep Digital Copies-And Know Your Insurance

Take a photo of every prescription bottle. Save the doctor’s letter as a PDF. Email it to yourself and a trusted family member. Save your insurance card and policy number in your phone. Most insurers now have apps where you can access digital prescriptions. UnitedHealthcare rolled out digital verification in November 2023. CVS Health’s app lets you request refills while traveling.

Also, know your plan’s out-of-network rules. If you need to refill at a pharmacy outside your network, will your insurance cover it? Some plans only cover in-network pharmacies abroad. Others reimburse you after the fact. Call your insurer before you leave. Ask: “If I refill my prescription overseas, what documentation do I need to get reimbursed?”

Why This Matters More Than You Think

Medication non-adherence during travel causes 23% of travel-related hospitalizations, according to a 2021 study in the Journal of Travel Medicine tracking over 15,000 travelers. That’s not a small number. That’s one in four. And 78% of those emergencies could’ve been prevented with simple planning, according to Express Scripts.

This isn’t about being overly cautious. It’s about being prepared. You plan your flights, your hotels, your itinerary. Why wouldn’t you plan your meds? Your health doesn’t take a vacation. Neither should your treatment.
