Traveling with injectable medications like insulin, EpiPens, or hormone injections doesn’t have to be stressful-if you know the rules. Every year, over 15 million Americans rely on daily injectables, and many of them fly. The TSA lets you bring these supplies on board, but there are specific steps you must follow to avoid delays, confusion, or worse-being turned away at security.
What You Can Bring on the Plane
You’re allowed to carry unlimited amounts of injectable medications and syringes on U.S. flights, as long as they’re for personal medical use. This includes insulin pens, auto-injectors, vials, prefilled syringes, and even unused needles. The TSA doesn’t limit the number of syringes you can carry, but they must be accompanied by the medication they’re meant to deliver. No prescription is required by law, but having one helps.
Medications that exceed the 3.4-ounce (100ml) liquid limit are exempt from the standard 3-1-1 rule. That means your 10ml insulin vials, 30ml GLP-1 pens, or 50ml hormone solutions can all go through security-even if they’re in a bag full of liquids. Just tell the TSA officer you have medical liquids before you start screening.
Sharps Containers Are Non-Negotiable
Used syringes and needles can’t just go in your purse, pocket, or a random pill bottle. The TSA requires them to be stored in an FDA-approved sharps disposal container. These are rigid, puncture-resistant, and labeled with the universal biohazard symbol. You can buy these at any pharmacy for under $5, or use a dedicated travel sharps container designed for flying.
Why does this matter? In 2022, the FAA reported 17 needlestick injuries to flight crew members over four years-most from improperly stored sharps. Airlines and TSA officers are trained to flag loose needles as a safety hazard. Even if you think you’re being careful, a loose syringe in your bag could cause a full bag search, delay your flight, or get your meds confiscated.
Look for containers that meet ANSI/ISEA Z308.1-2021 standards. Brands like BD, Becton Dickinson, and Sharps Safety make compact travel versions that fit in a coat pocket. Never reuse a grocery bag, soda bottle, or yogurt cup-even if it seems sealed. TSA officers will reject them.
Keep Medications in Original Packaging
While the TSA doesn’t legally require it, keeping your medication in its original pharmacy-labeled container is the single best way to avoid questions. The label should show your name, the drug name, and the prescribing doctor’s info. If you’ve transferred pills to a pill organizer, bring the original bottle along.
For insulin and other temperature-sensitive drugs, don’t remove them from their box. The packaging helps TSA officers quickly identify the item. If you’re carrying multiple medications, keep each in its own labeled container. Mixing them increases the chance of a mix-up during screening.
Pro tip: If your medication doesn’t have a label (like a custom compound), bring a doctor’s note on letterhead. It’s not mandatory, but it cuts screening time by half.
Use the TSA Notification Card
One of the easiest ways to reduce stress at security is to hand the officer a TSA Notification Card (Form TSA-11-032). It’s a small printed card that explains you’re carrying medical supplies. You can download and print it from tsa.gov.
Since its launch in 2022, the card has reduced miscommunication by 29%, according to TSA’s own data. Passengers who use it report fewer delays and less questioning. You don’t need to show it unless asked-but having it ready shows you’re prepared.
Some travelers print multiple copies and keep one in each bag. Others laminate them and carry them like a credit card. Either way, it’s a simple tool that makes a big difference.
Temperature Control for Sensitive Medications
If your medication needs to stay cool-like insulin, growth hormone, or some biologics-you can bring ice packs, gel packs, or insulated bags. There’s no size limit. You can even bring a small cooler with frozen gel packs, as long as it’s clearly for medical use.
Don’t put ice packs in the same bag as your sharps. Keep them separate. TSA may need to inspect them separately, and mixing them can cause confusion. If you’re using a cooler, leave it unzipped or open so officers can see inside without touching anything.
Never freeze insulin. Most insulin types lose effectiveness if frozen. Keep it cool, not frozen. A reusable cold pack wrapped in a cloth towel is ideal. You can also buy small battery-powered insulin coolers (like the Frio or MedAngel) that are TSA-approved and don’t require ice.
Domestic vs. International Travel Differences
Within the U.S., TSA rules are consistent. But if you’re flying internationally, things change. European airports follow EASA rules, which sometimes require documentation in the destination country’s language. Japan, for example, requires a special permit for any syringe over 10 units. Australia and Canada have strict rules on syringe quantities without a doctor’s note.
Always check your destination’s medical import rules at least 30 days before you fly. The U.S. State Department’s travel website has a section for medical supplies by country. Some countries ban syringes entirely unless you have a letter from your doctor translated into their language.
On international flights, you may be asked to show proof of medical need. A prescription or doctor’s note in English is usually enough, but if you’re flying to a non-English-speaking country, get it translated. Many pharmacies offer translation services for free.
What to Do at Security
Arrive at the airport 30-45 minutes earlier than usual. Medical screening takes longer. When you get to the checkpoint, tell the officer: “I have medically necessary injectables and sharps.” Don’t wait for them to ask.
Remove your medications and sharps container from your bag and place them in a separate bin. Keep them visible. Don’t hide them. TSA officers are trained to look for medical items, but they can’t see them if they’re buried under clothes or toiletries.
Ask for a visual inspection if you’re carrying temperature-sensitive meds. X-ray machines can damage insulin and other biologics. Most TSA officers will accommodate this request if you ask politely. If they refuse, ask to speak to a supervisor. You have the right to request a private screening.
If you use an insulin pump or continuous glucose monitor (CGM), you can wear it through security. You don’t need to remove it. But if you’re asked to take it off, say it’s a medical device and you can’t disconnect it. Most officers will let you keep it on.
Real Traveler Experiences
A 2023 survey of over 2,000 travelers with injectables found that 82% had no issues when using proper sharps containers. Only 47% succeeded when using makeshift containers like pill bottles or ziplocks.
One traveler from Seattle reported a 45-minute delay at a small Midwestern airport because her insulin vials weren’t labeled. She had to call her doctor for a new label sent to the airport. She now keeps a spare label in her wallet.
Another passenger flying from Chicago to Tokyo brought her insulin in a small cooler with frozen gel packs. The officer initially wanted to confiscate it. She showed her doctor’s note and the FDA label on the vial. They let her through with a nod and a thank you.
People with insulin pumps say PreCheck reduces screening time by about 50%. If you travel often, it’s worth the $78 fee. You’ll breeze through security with your meds already flagged in the system.
What Not to Do
Don’t tape syringes to your body. It looks suspicious and can trigger a full-body scan. Don’t try to sneak meds in your shoe or underwear. TSA has seen it all-and they’ll find it.
Don’t rely on airline staff to know the rules. Flight attendants aren’t trained in TSA policy. If you have a question, ask a TSA officer, not the gate agent.
Don’t forget to pack extra supplies. Flights get delayed. Layovers stretch. Pack at least two days’ worth of meds and syringes in your carry-on. Never check your injectables. Checked luggage gets lost, delayed, or exposed to extreme temperatures.

Traveling with injectables isn’t about jumping through hoops. It’s about being prepared. The rules exist to protect you and others. Follow them, and you’ll get through security smoothly-every time.
Can I carry syringes without medication on a plane?
No. TSA requires that all syringes be accompanied by the corresponding medication. Carrying unused syringes without any medication may lead to confiscation or delays. Always keep your syringes with your insulin, EpiPen, or other injectable drug.
Do I need a doctor’s note to fly with insulin?
No, the TSA does not require a doctor’s note for insulin or other injectables. However, having one can help avoid delays, especially at smaller airports or when traveling internationally. A note on letterhead from your doctor confirms the medical need and reduces questions.
Can I bring my insulin pump through airport security?
Yes. Insulin pumps and CGMs are allowed through security while worn. You don’t need to remove them. If asked, explain it’s a medical device. TSA officers are trained to recognize these devices. You can request a pat-down instead of a full-body scan if you prefer.
Are there restrictions on sharps containers for international flights?
Yes. While U.S. airlines follow TSA rules, international destinations may have stricter limits. Japan requires a permit for more than 10 syringes. Australia and Canada may ask for a doctor’s letter. Always check the destination country’s medical import rules before you fly.
Can I check my insulin or syringes in my luggage?
Never. Checked baggage is exposed to extreme temperatures and can be lost or delayed. Always carry your injectables, syringes, and sharps containers in your carry-on. The TSA allows this without restriction as long as you follow the guidelines.
