How to Carry Injectables, Syringes, and Sharps on Airplanes: A Clear, Step-by-Step Guide

Traveling with injectable medications like insulin, EpiPens, or hormone injections doesn’t have to be stressful-if you know the rules. Thousands of people fly with these supplies every day, but too many face delays, confusion, or even denied boarding because they weren’t prepared. The good news? The rules are clear, and with the right steps, you can move through security smoothly and safely.

What You’re Allowed to Bring

The TSA allows injectables, syringes, and sharps on airplanes without any limit on quantity, as long as they’re for medical use. This includes insulin pens, auto-injectors, vials, needles, and unused syringes. You don’t need a prescription to bring them, but you do need to show they’re yours.

Used syringes? Also allowed-but only in an FDA-approved sharps container. No ziplock bags, no empty pill bottles, no coffee stirrers stuck in a foam cup. Those won’t fly. The container must be rigid, puncture-resistant, and labeled with the universal biohazard symbol. Think of it like a hard plastic case with a secure lid-exactly what pharmacies give you when you pick up insulin.

Liquid medications over 3.4 ounces (100ml) are exempt from the standard liquids rule. That means your 10ml insulin vials, 30ml heparin syringes, or 50ml growth hormone vials? All fine. But you must declare them at the security checkpoint. Don’t wait for an officer to ask-speak up before you reach the X-ray machine.

How to Pack It Right

Here’s the simple checklist most travelers miss:

1. Keep all medications in their original pharmacy-labeled containers. The label must show your name and the drug name. If it’s been repackaged into a pill organizer, bring the original bottle too.
2. Use a hard-sided sharps container. Look for ones labeled ANSI/ISEA Z308.1-2021 or IATA Packing Instruction 650. Brands like BD, Novo Nordisk, or Lilly make these-many are even TSA-approved.
3. Put your sharps container and medication bottles in a clear plastic bag. It helps security see what’s inside without opening anything.
4. Don’t pack sharps in checked luggage. If your bag gets lost, you lose your meds. Always carry them on.
5. For temperature-sensitive meds like insulin, use a cooler with an ice pack or gel pack. TSA allows unlimited ice packs as long as they’re not frozen solid. A slightly slushy pack is fine.

Pro tip: If you’re carrying an insulin pump or continuous glucose monitor (CGM), keep it on your body. Don’t put it in your carry-on. Officers may ask to inspect it, but they’ll usually let you keep it on during screening.

What to Say at Security

Approach the TSA officer before you reach the X-ray belt. Say clearly: “I have medical supplies with me-insulin, syringes, and a sharps container.” Hand them your items in a clear bag. If you have a TSA Notification Card (Form TSA-11-032), hand it to them. It’s free to download, and it cuts down on questions by 29%.

Don’t get defensive if they ask to inspect your meds. They’re trained to look for threats, not to judge your health. A simple, calm response works best: “This is my insulin. My name is on the label. I need it to stay healthy.”

Request a visual inspection if you’re worried about your meds being X-rayed. While X-rays won’t harm insulin or most injectables, some people prefer to avoid it. TSA officers are required to accommodate that request.

International Travel? Check the Rules

Domestic U.S. flights follow TSA rules. International flights? It gets trickier.

European airports follow EASA rules, which often require your medication documentation to be in the destination country’s language. Japan requires a special permit for more than 10 syringes. Australia and Canada allow injectables but may ask for a doctor’s note. Some countries ban syringes entirely unless you have prior approval.

Don’t wait until the airport to find out. Go to the embassy website of your destination country 30 to 60 days before you fly. Search for “import of medical devices” or “carrying syringes.” If you’re unsure, email them. Better safe than stranded.

Real Stories: What Works

A woman from Texas flew to Hawaii with her 12-year-old son who has Type 1 diabetes. She packed his insulin in original bottles, used a hard sharps container, and brought a doctor’s note. She declared everything upfront. No delays. No questions. She said it was the first time she felt “seen” at security.

Another traveler from Florida tried bringing syringes in a pencil case. The officer didn’t recognize it as medical equipment. He had to go to a secondary screening, missed his flight, and spent three hours waiting. He didn’t have a doctor’s note or original labels. Lesson learned.

According to a 2023 TripAdvisor survey of over 2,000 travelers with injectables, 82% had no issues when they used proper sharps containers. Only 47% succeeded when they used makeshift containers. The difference isn’t luck-it’s preparation.

What to Avoid

• Don’t rely on airline staff to know the rules. Flight attendants aren’t trained in TSA policy. Security officers are.
• Don’t hide your meds. If they’re found later in your bag, you could be flagged for suspicious behavior.
• Don’t assume your doctor’s note is required. It’s not mandatory for U.S. flights-but it helps. Keep one handy.
• Don’t bring extra syringes without medication. TSA has flagged passengers for carrying 50 empty needles. Always pair syringes with the drug they’re meant for.

Special Cases: Insulin Pumps, CGMs, and More

If you use an insulin pump or CGM, you can keep it on during screening. Tell the officer it’s a medical device. They may ask you to turn it off briefly, but they won’t make you remove it. TSA has specific training for these devices now, thanks to a 2022 update to their Medical Screening Reference Guide.

For travelers with multiple medications-say, insulin, glucagon, and injectable antibiotics-group them together in one clear bag. Label each item with a sticky note: “Insulin,” “Glucagon,” “Antibiotic.” It saves time and reduces confusion.

What If You’re Denied?

It’s rare, but it happens. If an officer says no, ask to speak to a supervisor. Mention the TSA’s official policy on medical supplies (available on tsa.gov). If you’re still blocked, ask for a complaint form. You have rights under the Air Carrier Access Act of 1986, which protects passengers with disabilities from discrimination.

Document everything: who you spoke to, what they said, the time and terminal. Send a copy to TSA’s Customer Service team. They track these incidents and retrain staff when patterns emerge.

Final Tips for Stress-Free Travel

• Arrive 30-45 minutes early for extra screening time.
• Use TSA PreCheck. It reduces medical screening delays by about half.
• Carry a printed copy of TSA’s Medical Supplies page (tsa.gov/travel/special-procedures/medical-supplies) in your wallet.
• Practice at home. Pack your bag like you’re going to the airport. Do a dry run.
• Know your rights. You’re not asking for special treatment-you’re exercising your legal right to medical care while traveling.

Traveling with injectables isn’t about bending the rules. It’s about following them-clearly, confidently, and calmly. The system works when you do your part. And you’ve got this.
