Yes, medicine is allowed in hand luggage; pills are fine, and liquid meds can exceed 100 ml when screened and declared, with proof where needed.
What This Rule Means
Airport screening today looks for safety risks, not to take away your treatment. Solid pills fly with you. Liquid medicine travels too, even when a bottle is larger than 100 ml, as long as it is checked by security. Bring only what you need for the trip and keep the rest in checked bags. Keep labels visible and your name on the box when possible.
Rules share the same core idea across regions: necessary medicine stays with the passenger. The screening team may swab, scan, or ask a quick question, then wave you through. A calm, tidy pack makes the line faster and keeps stress low.

Taking Medicine In Hand Luggage: The Practical Rules
Set up your carry-on so staff can see your medicine quickly. A clear pouch near the top of your bag works well. Put any liquid medicine and cooling packs in that pouch and be ready to place it in a tray. Tell the officer you have medicine before the bag goes through the scanner.
Pack It Right
Keep boxes, leaflets, and printed labels when you can. Names on the packs should match your travel ID. If your pharmacy prints small labels, add a simple card with the drug name, dose, and patient name. Split doses across two bags when travel spans many hours, so one delay does not spoil your plan.
Documents That Smooth Screening
Carry a short letter or a digital note that states your diagnosis or need, drug names, and any supplies like needles or gel packs. A printout of your prescription or an e-prescription screen grab helps too. For controlled drugs, bring the official paperwork used in your country.
At The Security Checkpoint
Tell the officer that you carry medicine and place the pouch in a tray. In the United States, the TSA medication rules allow liquid medicine beyond 3.4 oz when declared. In the United Kingdom, CAA guidance on medicines confirms that needed liquid medicine and items like needles can travel in hand baggage when screened. Across the European Union, a Commission notice says some airports have returned to classic liquid limits for regular items; the medicine exemption still applies when screened.
Place cooling packs beside the bottles so screeners can see everything in one glance, and keep the rest of your liquids bag separate to avoid confusion at the tray during screening for staff.
Temperature-Controlled Drugs
Insulin, biologics, and some eye drops prefer a narrow temperature range. Use insulated pouches with gel packs. Pack a spare gel pack in case one warms up. If your route includes long layovers, ask a café for a cup of ice and refresh the pack. Never freeze insulin; aim for cool, not rock solid.
Needles, Syringes, And Sharps
Bring a small, rigid case or a travel sharps bin. After use, recap only if the design allows it. Many airport toilets have bins for sharps; cabin crew can help if you cannot find one. Keep a note or script that mentions your need for needles to avoid delays at screening.
Liquid Rules And Daily Care Items
Saline, contact lens solution, and medical rinses count as medicine when needed for the trip. Declare them and carry proof when the bottle is large. Keep cosmetic liquids in a separate quart bag so staff can process your tray quickly.
Are Medicines Allowed In Cabin Luggage On International Flights?
Yes. The same theme holds worldwide: medicine that a passenger needs during the trip stays in the cabin. What changes is the way airports screen large liquid containers and the papers staff may ask for at the gate. That is why a simple letter and labeled packs save time in any region.
United States
Screeners allow pills in any amount. Liquid medicine can exceed the usual 3.4 oz limit when declared and screened. You do not need to place medical liquids in the zip bag used for toiletries. Keep them separate and mention them before the scan.
United Kingdom
Hand luggage can include needed liquid medicine over 100 ml and related gear like needles and gel packs when needed for your trip. Staff may ask for proof that the medicine belongs to you when the container is larger than 100 ml. Keep a script or letter handy.
European Union
EU airports use the 100 ml rule for general liquids in the cabin. Medicine for the trip is exempt when checked by security. Some airports with new scanners trialed larger bottles for all liquids, then moved back to the classic rule for now. The medicine exemption remains, with screening at the checkpoint.
Other regions follow the same logic. Labels, clear packing, and a short letter reduce questions and keep your line moving.
Carry-On Vs Checked: What Goes Where
Keep all active medicine in your hand bag. Checked bags can be late, hot, or cold. Pressure changes and long holds can spoil liquids. Carry spares in case one dose leaks or a cap cracks. Pack heavy backup supplies, like extra tubing or bulk liquids, in checked luggage only if you can miss them for a few hours.
Medical devices that you need during flight stay with you. Many airlines do not count a small medical bag against your cabin allowance. Print the page from your airline if you plan to bring a device like a CPAP or a portable nebulizer.
Quick Region Snapshot For Hand Luggage Medicine
| Region | Liquid Medicine In Cabin | Proof Often Requested |

| USA | Allowed beyond 3.4 oz when declared and screened | Not required by rule; a script or label helps |
| UK | Allowed beyond 100 ml when needed | Letter or prescription when bottle exceeds 100 ml |
| EU | Allowed when screened; general liquids follow 100 ml rule | Short note or label with passenger name |
Packing Checklist For Medicine In Hand Luggage
The Essentials
- Labeled medicine packs for the full trip, plus a buffer dose.
- A clear pouch for fast screening access.
- Printed scripts or a doctor’s letter stored with your passport.
- Cooling sleeves and gel packs when needed.
- A small sharps case for needles or lancets.
- Spare caps, pen tips, test strips, and wipes.
- Snacks or glucose tabs if your care plan calls for them.
Smart Backups

Common Mistakes To Avoid
Hiding Medicine At The Bottom Of Your Bag
Screeners need to see it. Place the pouch on top so you can lift it out fast. This small move trims minutes from the line and keeps your blood pressure steady.
Decanting Into Unlabeled Bottles
Loose pills in a baggie invite questions. Keep factory packs or pharmacy packs when you can. If you must split doses, copy the label and slip it inside the travel vial.
Checking All Supplies
Flights get delayed. Bags miss connections. Keep active treatment with you so care stays on track even when the trip goes sideways.
Forgetting Temperature Needs
Many drugs lose strength when cooked or frozen. Use insulation and swap gel packs when warm. Ask crew for ice if a long delay pops up.
Special Cases And Tips
Oxygen And Nebulizers
Airlines need notice for oxygen service. Portable concentrators listed on the airline site can fly, but you must bring charged batteries for the full flight time plus a buffer. Keep the device under the seat with the intake clear.
Insulin Pumps And CGM
Most pumps and sensors can go through walk-through scanners and hand checks. If your device maker advises skipping X-ray for the pump, ask for a pat-down and a visual check. Carry printouts that show the device model, so staff can see what you carry.
Controlled Drugs
Rules vary by country. Carry the original pack with your name and dose. Bring the permit used where you live if your drug appears on a controlled list. Keep all papers together so you can show them at customs if asked.
Travel Delays And Missed Doses
Set phone alarms and keep spare doses in a second pocket of your pouch. If a connection slips, you will still have the next dose at hand. A small routine beats stress every time.
If Your Medicine Is Flagged At Security
Stay calm and speak clearly. Tell the officer that the item is medicine and that you need it during travel. Ask for a private room if you prefer not to open a kit in public. You can ask for a lead officer if a question stalls the line.
Keep digital copies of labels and letters on your phone. If a paper letter is in a checked bag by mistake, that image can save time. When language gets in the way, point to the drug name on the box and use a simple line like “for diabetes” or “for asthma.” Short words help both sides move faster.
In the U.S., travelers who need extra help can call TSA Cares before travel to arrange checkpoint help.
Medication Packing Layout That Works
Think in layers. Place the clear pouch at the top of your cabin bag. Right under it, keep chargers and a small power bank. Slip your paper scripts and a spare gel pack in a side pocket. This layout puts the most requested items within one quick reach at every point.
If you cross time zones, mark doses on your phone using the departure time and adjust after boarding. That way the alarm fires when you expect. Cabin crew can bring water for pills; ask early.
Simple Step-By-Step Plan
- Make a list of every drug, dose, and device you need during the trip.
- Fill a clear pouch with those items and place it at the top of your carry-on.
- Add scripts, a short letter, and any permits for controlled drugs.
- Add cooling gear and a spare gel pack if your medicine needs it.
- Charge medical devices and pack chargers and spare cells in the cabin.
- At security, tell the officer that you carry medicine and place the pouch in a tray.
- On board, keep the pouch under the seat in front so you can reach it fast.
With a tidy, labeled pouch and a few short lines of proof, you can carry medicine in hand luggage without drama. Your care stays with you, and your trip stays on track.
Carry the kit every time you fly. Keep it visible, labeled, and dry. Tell staff what you have, answer calmly, and move on. That simple habit keeps treatment safe while you travel.
