Hi Health Champions,

Let’s break down something I wish every traveler knew: how to fly with your medications, safely and without surprises.
You’d be amazed how often even the most careful folks get tripped up by confusing airport rules—or outdated advice.

✈️ Travel Story: Lisa’s Honeymoon Mishap

Lisa thought she planned every detail for her dream trip to Italy. Medications packed? Check. Prescriptions? Check. Insurance? Double check!

But at airport security, her insulin pens were taken for being “over 3.4 oz,” her glucometer triggered extra screening, and her sharps kit caused a long delay. By the time she got to her gate, she had no access to life-saving medicine for a 10-hour flight.

She told me later:
"I researched everything except the REAL TSA rules."
I want to make sure this never happens to you.

💉 Travel Medications & Vaccines: What You Really Need to Know

Travel vaccines aren’t something you squeeze in last-minute—and airport rules on medicine are different from what you might hear from friends.

Timing Your Travel Vaccines:

  • Start early: Many vaccines take 2–4 weeks to protect you fully (CDC Travel Vaccines & Timing).

  • Some need more than one dose: Hepatitis A/B and others are spread weeks apart (CDC 2025 Immunization Schedules).

  • Certain medications may affect your shots: Always bring your full medicine list to your travel doctor or pharmacist.

If You’re Short on Time:
Even if you missed the “early” window, it’s still worth getting the vaccines and advice you need today. Some protection beats none—and pharmacists can help with last-minute plans.

The Real TSA Rules for Medications on Flights:

  • All prescription meds are allowed in your carry-on—but they must be labeled, and it's best to keep them in original containers (TSA Medication Requirements FAQ).

  • Liquid medications over 3.4 oz? Allowed! Just tell TSA you have them (TSA What Can I Bring—Medications).

  • Diabetes supplies, inhalers, and refrigerated meds? All allowed—bring ice packs if needed, and tell security.

  • Bring documentation: Doctor’s letter for controlled substances, paper/phone photos of your prescription labels, and an ID matching your meds.

Never pack meds you need during travel in checked luggage!
Always pack extra doses, just in case (TSA Travel Tips 2025).

Lisa’s Next Trip Was a Breeze
She used these real rules, planned ahead, and breezed through airport security—with all her medicine.

Stories like Lisa’s are why I care so much about helping people feel truly prepared—not just for travel, but for life’s unexpected challenges. Whether I’m supporting patients or mentoring pharmacists, my goal is always to make complex things simpler, to provide encouragement, and to share real-world strategies that boost confidence.

👩‍⚕️ Leadership Lens: Building Future Pharmacy Leaders

This summer, I mentored three pharmacy students. Watching them learn in real-world scenarios reminded me how important it is to teach with support, patience, and kindness—especially under pressure.

My best takeaways:

  • Start with observation and simple tasks—let learners build confidence.

  • Celebrate questions and mistakes as growth, not problems.

  • Give students real projects that matter.

  • Recognize their wins—big and small.

If you’re a leader (or want to become one!), remember: the best confidence comes from support, not just knowledge.

Q: What medications CAN I bring on a plane?
A: Almost anything your doctor prescribes, as long as you follow a few key steps:

  • Pack everything in your carry-on, labeled and in its original container if possible.

  • Liquids over 3.4 oz? Inform security—they’re allowed with prescription.

  • Controlled substances? Bring your prescription label and (if possible) a doctor's letter.

  • Bring extra, in case of delays.

Stay healthy and safe on your travels,
Dr. Lee
