Flying with Medication: A 2025 Comprehensive Guide

Flying with medication can feel like a minefield—one small mistake at security or customs, and your trip could unravel.

A traveler once emailed me in a panic from the Doha airport. She’d packed her blood pressure meds in a labeled bottle but forgot the original box and a doctor’s letter. The customs officer didn’t recognize the brand—and confiscated her entire supply. She had nothing for a 10-day trip.

Rules vary wildly between TSA and international customs. What’s allowed in the U.S. might be banned abroad. One oversight—like missing paperwork or unlabeled pills—can lead to delays, confiscation, or worse.

That’s why I created this guide: to help you fly worry-free with your medications. You’ll learn what TSA permits, which countries have zero-tolerance laws, and how to pack your meds so they make it through every checkpoint. If you’re flying to the Middle East, parts of the Far East or Southeast Asia, be sure to check my chart on Banned and Restricted Medications in this post – it could save your trip.

❌ 1.2 Most Common Mistakes That Cause Problems

Packing Errors:

• Putting medications in checked luggage where they can be lost, stolen, or damaged by temperature extremes
• Mixing different pills in unmarked containers, which raises red flags at security
• Bringing banned substances to strict countries without researching laws first
• Forgetting to pack extra medication in case of travel delays

Security & Customs Mistakes:

• Not declaring liquid medications at TSA checkpoints (they’re allowed but must be screened)
• Leaving prescription bottles behind at security after additional screening
• Failing to have proper documentation for controlled substances
• Not knowing your rights when selected for additional screening

1.3 See a Doctor Before Travel If:

🚨 You’re taking controlled substances internationally – Many countries ban or heavily restrict medications like Adderall, Xanax, or prescription pain relievers. Your doctor can provide a medical letter or suggest alternatives.

🚨 Your destination has strict drug laws – Countries like Japan, UAE, and Saudi Arabia have zero-tolerance policies. Even common over-the-counter medications can be illegal.

🚨 You need more than a 90-day medication supply – Most countries allow 30-90 days for personal use. Longer supplies may require special permits.

🚨 You’re traveling with injectable medications – Insulin, EpiPens, and other injectables require additional documentation and proper storage considerations.

2. TSA Rules (US Domestic Flights)

The good news about domestic US travel? TSA’s medication policies are designed to be traveler-friendly. Here’s exactly what you need to know for each type of medication.

⚠️ ❗ Special Rules for Controlled Substances

If your medication falls into the controlled substance category, you can still leave it in your bag. If TSA asks to inspect it, it’s to verify it’s legitimately prescribed to you.

• Medication must be in original prescription bottles with your name clearly visible
• Doctor’s letter required explaining the medical necessity
• Common controlled medications include:
  • Opioid pain relievers (OxyContin, Percocet, Vicodin)
  • Benzodiazepines for anxiety (Xanax, Valium, Ativan)
  • ADHD medications (Adderall, Ritalin, Vyvanse)
  • Sleep aids (Ambien, Lunesta)
  • Some muscle relaxers

2.1 Prescription Pills

💊 What TSA Allows:

• Pill organizers are completely allowed – You can sort your weekly medications however works best for you; read about my favorite ones–practical and affordable.
• No quantity limits – Bring as much as you need, plus extra for delays
• Always pack in carry-on – The cargo hold isn’t temperature controlled and you won’t have access during flights; in addition, if you pack in a checked bag and it is lost, your medication must be replaced
• Original bottles recommended but not required – except for controlled substances

KEEN TIP: Keep your medication pouch near the top of your carry-on so you can access it quickly if TSA needs to inspect it.

🧴 Guidelines for Liquid Medications:

• No size restrictions for medical liquids
• Must be declared at the security checkpoint – tell the agent before screening begins
• Place in separate bin for individual screening
• Pack in clear, labeled containers when possible
• Bring documentation – prescription label or doctor’s note explaining necessity

Screening Process: TSA agents may need to test liquid medications using specialized equipment. This is routine and takes just a few minutes. Having a doctor’s letter or prescription label makes this process smoother and faster.

KEEN TIP: Visit our guide on Flying with Liquid Medication for specific advice on packing, preventing leaks at altitude and the best travel containers for medical liquids.

2.3 Injectable Medications

Traveling with insulin, biologics, EpiPens, or other injectable medications requires a bit more preparation, but TSA is familiar with these medical necessities.

💉 How to Carry Medical Devices and Injectables:

• Always pack in carry-on – never put life-saving medications in checked luggage
• Bring a doctor’s letter explaining what the device is and why you need it
• Inform TSA agents before screening – declare your medical devices upfront
• Keep easily accessible – don’t bury them in your bag
• Bring a sharps container and cooling supplies if needed – insulated cases and ice packs are allowed

🟢➡️ Read How to Travel With Refrigerated Medication for easy, expert tips.

Additional Tips:

• Insulin and Insulin Pumps: TSA permits all insulin supplies including pens, vials, and pumps. Insulin pumps can stay attached during screening (inform agent when you approach), though you may be asked to show the device. Any disconnected devices may be screened by X-ray. Inform TSA if you do not want your device screened by X-ray. Alternative screening will be conducted.

• EpiPens and Emergency Injectors: Keep these in original packaging when possible. Consider wearing a medical alert bracelet if you have life-threatening allergies—it helps first responders and TSA agents understand your situation quickly.

🟢➡️ Cooling cases and backup supplies are allowed without restrictions. Separate your medical pouch or cooling case for individual inspection. For more details, read Flying with an Insulin Pump.

📌 Required Documentation for Injectables:

• Doctor’s letter including: Your medical condition, medication names and dosages, confirmation that the medication is medically necessary and your doctor’s contact details
• Device documentation: If possible bring an image of the packaging for the devices you’re carrying (auto-injectors, pumps, etc.) (Download from the computer if the box is long gone)

KEEN TIP: Always pack backup supplies including spare prescriptions. If your luggage is delayed or devices malfunction, you’ll need immediate replacements.

🟢➡️ Read more in our complete article on Flying with Injectables.

2.4 Over-the-Counter Medications

Over-the-counter medications are the easiest to travel with domestically. TSA allows them in both carry-on and checked bags without special documentation.

📌 Best Practices:

• Keep in original packaging to avoid confusion or suspicion
• Don’t combine medications in unmarked containers
• Common OTC meds are fine: Pain relievers, cold medicine, antacids, allergy medications
• Read How to Pack Over-the-Counter Meds for Air Travel Anywhere

KEEN TIP: Even though TSA doesn’t require it, keeping a simple list of your OTC medications can be helpful if questions arise.

3. International Travel Rules

International travel introduces an entirely different set of challenges. Medications that are perfectly legal and common in the US can be restricted, banned, or even result in arrest in other countries. My advice is if you’re not sure, just leave it at home. The key is research and preparation.

3.1 High-Risk Countries with Strict Medication Laws

🔺 ALERT: Some countries have strict rules about medications—even common ones.
From banned ingredients to permit requirements, it’s easy to get caught off guard. Before you fly, it’s essential to check whether your meds are allowed and what documentation you’ll need.

🚫🔴 Japan – Surprisingly Strict Policies

Japan has some of the world’s most restrictive medication laws, and many travelers are caught off guard. Even common over-the-counter drugs can land you in serious legal trouble. Read Surprising Medications Not Allowed in Japan to learn more.

Completely Banned Medications:

• Benadryl (Diphenhydramine) – Considered a controlled substance, completely illegal to import
• Sudafed (Pseudoephedrine) – Found in many cold medications, strictly prohibited
• ADHD medications – Adderall, Ritalin, and similar stimulants are banned without exception
• Codeine – Restricted in both prescription and over-the-counter forms (common in cough syrups)

What Happens if Bring Banned Medications into Japan**

• Immediate detention upon arrival at the airport
• Mandatory drug testing procedures
• All medications confiscated permanently
• Possible arrest, court appearances, and deportation
• Legal consequences including heavy fines and potential jail time

**For some prescription medications, Japan offers an import certificate called Yunyu Kakunin-sho. You must apply well in advance through Japanese customs, provide detailed medical documentation, and receive approval before traveling.

🔴 Middle East Countries – Zero Tolerance Approach

Countries in the Middle East, particularly the UAE and Saudi Arabia, enforce some of the world’s strictest drug laws. Trust me, this is is not something you want to take lightly. What might seem like a minor medication issue elsewhere can result in serious legal consequences.

United Arab Emirates (UAE):

• Prescription pain medications are often completely banned
• Anti-anxiety medications like Xanax require special government approval
• CBD products including medical CBD are strictly forbidden
• Codeine-based medications require pre-approval and documentation

🔴 Saudi Arabia:

• Requires pre-approval for most prescription medications
• All medical documents must be translated into Arabic
• Controlled substances may be allowed only with official government permits
• Religious and cultural considerations affect medication acceptance

What to Expect:

• More thorough luggage searches than other regions
• Potential arrest on arrival for banned substances
• Court appearances and extended detention possible
• Heavy fines and jail time for violations
• Zero exceptions for “I didn’t know” explanations

KEEN TIP: Contact the embassy of your destination country at least 6-8 weeks before travel. They can provide current lists of banned substances and required documentation.

⚠️🔴 Singapore & Indonesia – Strict but Often Overlooked

Both countries have firm medication rules—yet they’re frequently missed by U.S. travelers.

⚠️ Singapore:

• Requires travelers to declare all prescription medications at customs
• Certain sleep aids, ADHD meds, and anxiety drugs are restricted
• Some medications require prior approval from Singapore’s Health Sciences Authority

🔴 Indonesia:

• Prohibits a range of psychotropic drugs, even with prescriptions
• Pain medications and sedatives are closely regulated
• May require a doctor’s note plus embassy documentation

🟢 Tip: Always carry meds in original packaging with your prescription label and a doctor’s note. When in doubt, declare it!

📌European Union – Complex but Manageable

The EU presents a mixed landscape. Traveling between member countries is relatively straightforward for most medications, but individual countries maintain their own restrictions, especially for controlled substances.

🟢➡️ Check out our detailed guide Common Medications Not Allowed in Europe: What Not to Pack for country-specific restrictions.

❗ ❕ ❌ Codeine-Based Medications: Codeine is more restricted across Europe than in the US. Countries like France, Norway, and Greece have specific limitations:

• Special import permits may be required
• Prescription from local doctor might be necessary
• Translated medical documents often mandatory
• Quantity limitations are strictly enforced

❕ ❌ ADHD Medications: Stimulant medications require extra documentation across the EU:

• Some countries ban these medications entirely
• Others require comprehensive documentation including:
  • Letter from your prescribing physician
  • Official doctor’s declaration forms
  • Import certificates from health authorities
  • Translated medical records

KEEN TIP: Always carry medications in original bottles with prescription labels, and bring translated doctor’s notes when possible. Research specific country requirements as they vary significantly within the EU.

3.2 Documentation Requirements for International Travel

Essential Paperwork:

• Original prescription bottles with labels showing your name (must match passport exactly)
• 🌟 Doctor’s letter translated into destination language when possible (get a FREE medical letter template)
• Generic medication names – international authorities recognize these better than brand names
• Prescribing physician contact information for verification if needed

Doctor’s Letter Must Include:

• Your full name exactly as it appears on your passport
• Clear explanation of your medical condition
• Complete list of medications with generic names
• Exact dosages and frequency of use
• Statement of medical necessity
• Doctor’s full contact information including phone number

KEEN TIP: If you go by a nickname or use your middle name differently on various documents, ensure your doctor includes all name variations to match your passport. My husband uses his middle name everywhere including with his doctors; fortunately, we spotted it on the letter he gave him and we asked him to revise it to show his legal name.

4. Packing & Preparation

Proper packing can make the difference between smooth travels and hours of delays at security or customs. Here’s how to organize your medications for stress-free journeys.

4.1 Essential Packing Rules

Packing Strategy for Different Trip Types

Here are guidelines from Airlines and Airport Security experts:

🧳 Short Domestic Trips (1-5 days):

• Small pill organizer for daily doses
• Original bottles for controlled substances
• Basic first aid supplies

🌍🧳🧳 International Travel:

• All medications in original bottles
• Translated documentation
• Extra supplies in separate bag
• Emergency contact information

🌍🧳🧳🧳 Extended Travel (Weeks/Months):

• Research prescription refill options at destination
• Bring maximum allowed supply
• Coordinate with doctors for extended prescriptions
• Consider travel insurance; VisitorsCoverage is an online platform that lets you compare plans.
• To cover evacuation to your home hospital/doctors in medical emergencies consider a company like Global Rescue.

4.2 Research Your Destination Thoroughly

Use this search method to find official, reliable information: Add “site:gov” to your search terms to pull up government websites only. This search will inform you whether you need to bring a doctor’s note for your medication, get a permit, or leave it at home altogether because it is banned.

Official Resources to Check:

• Health Canada (for Canada travel): “medication import rules”
• MHRA (for UK travel): “prescription medication travel guidelines”
• TGA (for Australia travel): “traveling with medication requirements”
• International Narcotics Control Board: Comprehensive database of controlled substances by country

Airline-Specific Policies: Don’t waste time on hold—use these efficient methods:

• Airline mobile apps: Start a chat with virtual assistant. I find this more efficient than phones because typically you are switched to a live rep once your question is answered and you say you need more information.
• Quick Google searches: Try “Delta traveling with insulin” or “Lufthansa ADHD medication policy”
• Live chat support: Most airline websites offer 24/7 chat support for medication questions. Go to their website.

What Embassies Can Help With

If online research doesn’t provide clear guidance regarding which medications might be restricted or banned, your country’s embassy in your destination should be able help:

• Verify which medications are allowed
• Explain required documentation
• Confirm whether special permits are needed
• Provide contacts for English-speaking doctors
• Assist if medications are confiscated

❗ KEEN TIP: Contact embassies 4-6 weeks before travel. Government responses can take time, and you may need to apply for special permits.

4.3 Medical Documents

Spend 15-20 minutes creating digital backups and save them on your phone, tablet or laptop—it’s one of the smartest investments you can make for travel security. You can also print copies and keep a set in your carry-on and one in your checked bag.

⚠️ ❗ Pack Essential Digital Documents:

• Scan medical documents into your phone or print copies
• Use your phone camera to take pictures of your medication bottles clearly showing both front label and prescription information in case they are lost or stolen
• Create a medication list with generic as well as brand names, names, dosages, time of day
• Save emergency contacts including your doctor, pharmacy, and insurance information

5. What to Expect at Airport Security & Customs

Knowing what to expect at security checkpoints and customs can eliminate anxiety and prevent costly delays. Here’s how to prepare.

5.1 TSA Security Checkpoint Process

• Have your medication bag easily accessible in your carry-on
• Place injectables, equipment, large liquid meds and controlled medication in a separate bin with your prescriptions and doctor’s letters.
• Screenings of devices and certain medications may take a few extra minutes so be patient

If Selected for Additional Screening:

• Don’t panic – Additional screening is often random or due to unfamiliar medical devices on scanner
• Stay cooperative – Answer questions honestly and briefly
• Have documentation ready – Don’t make agents wait while you search through bags
• Know your rights – You can request a supervisor or private screening if needed

5.2 International Customs Process

What Customs Officers Look For:

• Proper labeling – Medications in original containers with your name
• Reasonable quantities – Personal use amounts (typically 30-90 days supply)
• Valid documentation – Prescriptions and medical letters that support your needs
• Compliance with local laws – No banned or restricted substances

Typical Questions Asked by Customs Forms/Officers:

• “What medications are you carrying?”
• “What are these medications for?”
• “How long will you be in the country?”
• “Do you have prescriptions for these medications?”
• “Are you carrying any controlled substances?”

5.3 Your Legal Rights During Screening

👮‍♂️ Right to Supervisor Assistance: If there’s confusion, language barriers, or you feel screening is improper, politely ask: “May I speak with a supervisor, please?” Supervisors typically have more training and authority to resolve complex situations.

🚪 Right to Private Screening: You can request private screening including requesting a same-gender agent. There is no need to give a reason: Some people are uncomfortable being screened in public, others want pivacy to explain sensitive medical conditions and still others have medical devices that require removal or adjustment.

🧑‍🤝‍🧑 Right to Companion Presence: Your travel companion can stay with you during private screenings.

🧤💉 Right to Proper Handling: You can request that agents change gloves before handling your medical supplies. Medical equipment should be returned to you in working condition

6. Managing Medications Across Time Zones

6.1 Consult with Your Doctor

Before making any changes to your medication schedule, consult your prescribing physician. Different medications require different approaches to time zone adjustments. Some will say to stick to your home schedule, others will recommend a pre-travel adjustment.

Medication Reminder Apps:

• Medisafe: Excellent for tracking multiple medications with family sharing features
• MyTherapy: Combines medication reminders with symptom tracking and health journaling
• Dosecast: Specifically designed for complex medication schedules and time zone changes

Built-in Phone Medication Reminders

• iPhone Health app: Set up medication schedules with time zone adjustment features
• Google Assistant: Voice-activated medication reminders that travel with you
• Basic phone alarms: Simple, reliable backup system with custom labels

6.2 Long-Haul Flight Medication Management

In-Flight Organization Strategy:

Carry-On Packing:

• Pack all medications in carry-on – Never risk losing essential medications in checked luggage
• Use small travel organizer for doses needed during flight (keep original bottles in same bag)
• Easy access storage – Don’t bury medications deep in overhead bins
• Temperature considerations – Use cooling packs for heat-sensitive medications. Read all about Flying with Ice Packs.

Temperature-Sensitive Medication Care:

• Insulin and biologics require consistent temperature control
• Use insulated medication cases like Frio cooling wallets that don’t require electricity
• Avoid checked luggage – Cargo holds aren’t temperature controlled and can freeze or overheat medications
• Carry backup cooling supplies in case of equipment failure

6.3 Handling Travel Delays and Disruptions

Medication Supply Buffer: Always pack extra medication beyond your planned trip duration:

• Minimum: 3-7 extra days supply for domestic travel
• Recommended: 1-2 weeks extra for international travel
• Extended trips: Consider maximum legal supply allowed

7. Emergency Situations & Getting Refills

Despite the best planning, emergencies happen. Knowing how to handle lost, stolen, or confiscated medications can save your trip and your health.

9. Frequently Asked Questions (FAQ’s)

9.1 Packing & Documentation Questions

Q: Do I need to keep medications in original containers for international travel?

A: Yes, absolutely. For international travel, original labeled containers are essential. They provide proof that medications are legally prescribed to you and help avoid confiscation at customs. The prescription label should clearly show your name (matching your passport), medication name, dosage, and prescribing doctor information.

For domestic US travel, original containers are recommended but not legally required, except for controlled substances which must stay in original bottles.

Q: How much medication can I bring when traveling internationally?

A: Generally, you can bring a 30-90 day supply for personal use, but this varies significantly by country. Some nations allow only 30 days, while others permit up to 90 days. A few countries have no specific limits but require documentation for larger quantities.

Always check your specific destination’s rules, as exceeding limits can result in confiscation or legal issues. For extended travel, research local refill options rather than carrying excessive amounts.

Q: Do I need a doctor’s note for my medications?

A: For domestic US travel, doctor’s notes are required only for controlled substances (ADHD medications, anxiety medications, pain relievers, sleep aids).

For international travel, doctor’s notes are highly recommended for:

• All controlled substances
• Injectable medications (insulin, EpiPens, biologics)
• Large quantities of any medication
• Medications that might be restricted in your destination

The letter should include your condition, medication necessity, dosage information, and doctor’s contact details.

Q: Can my doctor’s note be in English, or does it need translation?

A: English is generally acceptable, especially at major international airports where customs agents are trained to read English medical documents. However, translation into the destination country’s language is recommended for:

• Countries with strict medication laws (Japan, Middle East)
• Remote destinations with limited English
• Extended stays where you might need local medical care
• Situations involving controlled substances

9.2 Security & Screening Questions

Q: Can I bring large bottles of liquid medication through airport security?

A: Yes. Liquid medications are exempt from the TSA 3-1-1 rule (3.4 ounces maximum for regular liquids). You can bring medically necessary liquids in any size, but you must:

• Declare them at the security checkpoint
• Place them in a separate bin for screening
• Have prescription labels or doctor’s documentation
• Be prepared for additional testing if requested

This applies to prescription cough syrups, liquid antibiotics, insulin, and other medical liquids.

Q: What should I say to TSA agents about my medications?

A: Be brief, honest, and proactive:

• “I have liquid medications that need separate screening”
• “I’m carrying insulin and diabetic supplies”
• “I have prescription medications including controlled substances”

Provide documentation immediately when requested. Don’t elaborate unnecessarily, but answer all questions honestly. TSA agents are trained to handle medical situations professionally.

9.3 Travel & Time Zone Questions

Q: How should I adjust my medication schedule for different time zones?

The best approach depends on your specific medications, medical conditions, and trip duration. Talk to your doctor: Some medications (like insulin) require careful timing adjustments, while others are more flexible.

Q: What apps help manage medications while traveling?

A: Top-rated medication management apps include:

• Medisafe: Multiple medication tracking with family sharing
• MyTherapy: Medication reminders plus health journaling
• Dosecast: Complex schedule management with time zone features

For simple needs, your phone’s built-in alarm and health apps work well. Set alarms with medication names and dosages as labels.

9.4 Emergency & Refill Questions

Q: What if I run out of medication while traveling abroad?

A: You’ll need to see a local doctor for a new prescription. This is crucial to understand: US prescriptions cannot be filled at foreign pharmacies. Here’s the process:

1. Find an English-speaking doctor or clinic
2. Bring your medication list, photos of prescription bottles, and doctor’s notes
3. Explain your situation and medical history
4. Get a new prescription written by the local doctor
5. Fill the prescription at a local pharmacy

Research medical facilities at your destination before travel, and consider travel insurance with medical coverage.

Q: Can my US doctor call in a prescription to a foreign pharmacy?

A: No. Foreign pharmacies cannot legally fill prescriptions from doctors licensed in other countries. This is true even for emergency situations. You must see a locally licensed doctor who can examine you and write a valid prescription according to that country’s medical laws.

Keep detailed medication lists with generic names, as international doctors and pharmacies recognize these more readily than US brand names.

Q: What if customs confiscates my medication?

A: If customs confiscates medication:

1. Stay calm and ask for documentation explaining the confiscation
2. Request to speak with a supervisor to ensure proper procedures were followed
3. Contact your country’s embassy for assistance and legal guidance
4. Seek local medical care immediately if the medication is essential
5. Document everything with photos, receipts, and written explanations

Embassies cannot reverse customs decisions but can help you understand your rights and find medical care. This is why researching destination medication laws before travel is so important.

9.5 Temperature & Storage Questions

Q: How should I pack medications that need refrigeration?

A: Use specialized cooling solutions designed for travel:

• Frio cooling wallets: No electricity required, activate with water
• Insulated medication cases with gel packs or ice
• Small travel coolers for larger medication supplies
• Backup cooling supplies in case of equipment failure

Never put temperature-sensitive medications in checked luggage, as cargo holds aren’t climate controlled and can freeze or overheat medications.

Q: Are cooling packs allowed through airport security?

A: Yes, cooling packs for medications are allowed even when partially or fully melted. Inform TSA agents that cooling packs are for medical purposes. They may need additional screening, but they won’t be confiscated when used for legitimate medical needs.

Bring backup cooling supplies and consider multiple smaller cooling packs rather than one large one for easier security screening.

9.6 Specific Medication Questions

Q: Are EpiPens and insulin pumps allowed on planes?

A: Yes, all medical devices including EpiPens and insulin pumps are allowed in carry-on bags. Key requirements:

• Inform security agents before screening begins
• Keep devices easily accessible for inspection
• Bring doctor’s documentation explaining medical necessity
• Insulin pumps can stay attached during screening
• Backup supplies are allowed without quantity restrictions

Consider wearing medical alert jewelry to help first responders and security agents quickly understand your medical needs.

Q: Can I bring medical marijuana or CBD products when flying?

A: This is extremely complex and risky:

• Domestic US travel: Depends on state laws at both departure and arrival locations, and CBD must be hemp-derived with less than 0.3% THC
• International travel: Most countries completely prohibit all cannabis products including medical marijuana and CBD
• High-risk destinations: Countries like Japan, UAE, and Singapore have zero tolerance with severe penalties including imprisonment

Even where legal, these products often create complications at security and customs. My advice is to leave them at home.

Q: Are there restrictions on over-the-counter medications internationally?

A: Yes, many countries restrict common US over-the-counter medications:

• Japan: Benadryl (diphenhydramine) is completely illegal
• Europe: Codeine-based cough syrups require prescriptions
• UAE: Many allergy and cold medications are restricted
• Singapore: Pseudoephedrine (Sudafed) is controlled

Never assume that over-the-counter status in the US means automatic acceptance elsewhere. Research your destination’s rules for all medications, including those you can buy without prescription at home.

10. Wrap Up

With proper preparation and the right information, traveling with medications can be straightforward and stress-free. The key is planning ahead, understanding the rules, and having backup plans for unexpected situations.

❗ ❕ ❌ 🚫 🛑 🔴10.3 Red Flags That Require Extra Preparation

Apply for permits, reach out to the embassy, speak with your doctor if:

• You’re taking controlled substances to countries with strict drug laws
• You need more than a 90-day medication supply
• Your medications aren’t available in your destination country
• You have complex medical devices requiring special handling
• You’re traveling to countries where your medications might be banned

Remember: Medication laws can change quickly, so always verify current regulations close to your travel date. When in doubt, contact official sources like embassies or health ministries rather than relying on informal advice.

Safe travels, and remember—A little preparation goes a long way toward ensuring your medications are there when you need them, wherever your journey takes you.
