Traveling Internationally with Insulin: A Step-by-Step Guide for Safe, Stress-Free Adventures

For people managing diabetes, the thrill of international travel comes with a few extra considerations—especially when it comes to carrying and storing insulin. But with the right preparation and tools, there's no reason your diabetes should hold you back from exploring the world.

✈️ 1. KNOW THE RULES: DOCUMENTATION & AIRPORT SECURITY

Every country has its own regulations for carrying medications across borders. To breeze through airport security and customs:

• Get a doctor’s letter: It should explain your diabetes diagnosis and list all insulin, medications, and devices you’re carrying.
• Use original packaging: Keep insulin and other meds in clearly labeled pharmacy containers.
• Bring your prescriptions: Carry printed copies and store digital versions on your phone or email.
• Declare your supplies: Let airport security know you're carrying medical supplies like insulin pens, needles, and pumps. Most staff are familiar, but clear communication helps.

Pro tip: In most countries, including Australia, the US, and the EU, passengers managing diabetes are allowed to bring insulin and related supplies in their carry-on under medical exemptions.

🌡️ 2. UNDERSTAND INSULIN’S TEMPERATURE NEEDS

Insulin is sensitive to extreme temperatures. Always double-check your insulin brand’s guidelines—some types tolerate slightly higher temps for short periods.

To keep it effective:

• Ideal storage: Insulin should be kept below 28°C (82°F) but never frozen.
• Heat damage: Prolonged exposure to high temps or direct sunlight can break it down.
  
• Cold risks: Insulin can lose potency if it freezes (under 2°C/35°F), especially in checked luggage or winter climates.

☀️❄️ 3. KEEP INSULIN SAFE IN ANY CLIMATE

In Hot Climates:

• Avoid direct sunlight—don’t leave insulin on dashboards or in hot bags.
• Use Glucology Insulin Cooling Pouches.
• Choose the coolest place in your hotel room
• Regularly inspect for cloudiness, discoloration, or clumps.

In Cold Climates:

• Never let insulin freeze. Below 2°C, it may lose effectiveness permanently.
• Keep it close to your body, like in an inner jacket pocket.
• Avoid leaving it in cars or outside pockets in freezing weather.
  

💧 4. USE A RELIABLE COOLING SOLUTION

Evaporative cooling pouches like Glucology Insulin Cooling Pouches are a great travel companion:

• No batteries or refrigeration required: Activate by soaking in cold water for 8–10 minutes.
• Keeps insulin cool for up to 36–45 hours, depending on the climate.
• Reusable: Reactivate as often as needed.
• Lightweight & portable: Great for carry-on luggage or daily excursions.
• Choose the right size: Options available for pens, vials, or both.

🧳 5. PACK MORE THAN YOU THINK YOU'LL NEED

Access to your specific insulin brand or diabetes devices isn’t always guaranteed overseas. So:

• Double your supplies: If you’re away for 7 days, pack for 14.
• Include everything: Pens/vials, needles, test strips, CGM sensors, pump supplies, and batteries.
• Split your stash: Keep one set in your carry-on, and one with your travel partner (or in a second bag).
• Optional: Leave a note inside hotel mini-fridges asking staff not to unplug or remove your medication.

⏰ 6. PLAN FOR TIME ZONE CHANGES

Adjusting your insulin schedule across time zones requires a bit of planning:

• Talk to your diabetes team: They can help you map out basal insulin timing or pump adjustments.
• Short trips (under 3 days) may not need major changes.
• Set reminders: Use your phone to remind you of injection times as you adjust to local time.
• Pack snacks: Travel delays and new foods can affect your routine. Keep fast-acting glucose (like Glucochews) within reach.

🛠️ 7. PRACTICAL ON-THE-GO STRATEGIES

• Re-activate your cooling pouch as often as needed by soaking it in water.
• Know your backup plan: Research local pharmacies or hospitals at your destination.
• Inspect insulin regularly: Discard anything that looks cloudy, discolored, or contains particles (unless it's meant to be cloudy like NPH insulin).
• Use a medical ID: Wear a bracelet or carry a card indicating your condition.
• Bonus Tip: Download a medical phrase card or diabetes translator app to explain your condition in the local language if needed.
