Solid oral medication is allowed in cabin baggage and is not subject to the 100 ml liquid restriction applied at security checkpoints. Present medicines separately when asked by screening staff and keep them accessible for inspection. Store pills in their labelled pharmacy containers whenever possible so names, doses and prescribing details are visible.
Fluids for medical use (syrups, injectable liquids, inhaler solutions) may exceed the 100 ml limit if accompanied by supporting documentation. Place these items in a clear bag and declare them at security control; expect manual checks and possible additional questioning. For injectable therapies bring needles and pens in original packaging plus a clinician’s letter describing medical need.
Certain active substances are subject to controlled‑drug rules in different countries. Carry a printed prescription listing the international nonproprietary name, total quantity, dosing schedule and prescriber contact details. Pack enough medicine for the trip plus a 48‑hour buffer and keep duplicates of prescriptions and a photo of the prescription on a mobile device.
Practical recommendations: keep all medicines in cabin baggage rather than checked bags; photograph prescriptions and medication labels; declare large medical liquids at security; verify the carrier’s policy and destination import rules before travel; obtain a dated clinician’s letter for controlled or injectable treatments.
Medication in cabin bags on low-cost carriers
Store prescribed pills in original pharmacy-labelled containers, add a printed prescription or clinician’s letter, and keep them in cabin baggage for immediate access during security checks and flight.
Security rules: oral solids are not restricted by the 100 ml liquids limit; liquid medicines (syrups, suspensions, injectable vials) over 100 ml must be declared at screening and presented with supporting documentation; expect manual inspection and occasional additional testing.
Controlled drugs (opioids, certain stimulants): carry a prescriber’s letter with generic names, doses, daily amounts and intended duration; verify import/export restrictions at destination and limit supply to roughly 90 days unless local rules allow otherwise.
Packing recommendations: keep original blister packs or bottles even if using a daily organiser; separate meds from toiletries to accelerate screening; avoid placing required doses in checked baggage because of loss or delay risk.
Injectables and temperature-sensitive medications: use an insulated pouch with a non-frozen gel pack and a clinician’s note; store syringes and sharps in an approved sharps container and declare them at security checkpoints.
At screening present medicines and documentation proactively when requested; if baggage is delayed or lost contact the airline’s customer service to request recovery or emergency support for required meds.

Permitted oral medicines and forms in cabin baggage
Store solid oral medicines (prescription and over-the-counter pills) in original blister packs or pharmacy‑labelled bottles with a copy of the prescription; security checkpoints normally allow unrestricted quantities of solids for personal use.
Specific forms and preparation
Solid pills & chewables: keep originals, add a printed prescription or pharmacy label, pack enough for the trip plus 48 hours extra, place in an easily screened pouch.
Effervescent/soluble products: leave sealed until screening; loose powder or granules may trigger additional inspection so retain manufacturer packaging.
Liquid medicines and syrups: allowed in volumes over 100 ml when medically necessary – present the product separately at security and show supporting documentation (prescription, doctor’s note or pharmacy label); prepare to have the item opened for inspection.
Inhalers & aerosol medications: permitted if for medical use; keep in original packaging, carry a prescription or written confirmation, and declare at security if requested.
Injectables, insulin & syringes: bring injectable medication in labelled containers with a prescribing note; store needles in sealed packaging or a travel sharps case and keep medication in the cabin – cooling packs permitted when required.
Transdermal patches, topical creams & gels: pack in original tubes/foil packs; gels over 100 ml follow liquid-med rules – carry supporting documentation.
Powders, vitamins & herbal supplements: original packaging recommended; powders may receive extra screening and for flights to the United States items greater than ~350 ml (12 oz) can be restricted by arriving-country security.
Controlled or narcotic medications: retain original prescription labels, carry a prescribing clinician’s letter, and verify destination country regulations before departure; minimise quantities to the treatment period required.
Quick practical recommendations
Always keep medicines in the cabin bag rather than checked baggage, place documentation with the items, allow extra time at security for inspections and declare any liquid medicines exceeding standard size limits. Use a dedicated, watertight pouch inside a travel bag – a reliable option is a best foldable duffel bag for travel to keep medication accessible. For unpredictable weather or long waits between connections, include compact protection such as the best tilting umbrella for patio in the same carry pouch.
How to pack liquid, effervescent or gel-based medication within the 100 ml rule
Use containers no larger than 100 ml for any dissolved or gel-form medicines and place them inside a single clear resealable 1-litre plastic bag; liquids required in volumes above 100 ml must remain in original packaging and be declared to security staff for inspection.
Specific packing steps:
1. Keep solid effervescent items in original blister packs whenever possible to avoid creating a liquid. 2. If dissolution is necessary before departure, transfer the solution into a labelled 100 ml bottle made of PET or HDPE, with tamper-evident cap. 3. For gel-based formulations, store in single-use ampoules or a 100 ml tube; consolidate multiple small items into one 100 ml container where dose integrity allows. 4. Attach a prescription label or copy of the prescription and note from the prescribing clinician, include drug name, strength, patient name and dosing schedule. 5. Present all medicinal liquids separately from other items at security screening and be prepared for additional inspection or testing.
Suggested packaging materials and marking:
Situation | Packing method | Documentation to include | Security action |
---|---|---|---|
Effervescent in original solid form | Keep in blister pack or tube; no liquid container needed | Original packaging or prescription label | Standard screening |
Effervescent dissolved ≤100 ml | Transfer to labelled 100 ml clear bottle, seal cap, place in 1‑litre bag | Prescription copy and date of preparation | Declare and show separately at security |
Effervescent dissolved >100 ml (daily dose requirement) | Keep in original pharmacy-labelled bottle | Doctor’s letter or prescription stating required volume | Declare to security; possible additional screening |
Gel-based medication ≤100 ml | Single 100 ml tube or vial, labelled, sealed, in 1‑litre bag | Prescription label or leaflet | Declare and present separately |
Gel-based medication >100 ml | Retain original labelled container; carry documentation | Prescription and clinician note | Declare; additional checks likely |
Packing tips for fewer delays: use clear containers with printed labels, keep one labelled daily-dose bottle rather than multiple small unlabelled vials, store documentation in an external pocket for quick access, and allow time at security for potential swab testing or X-ray inspection.
What prescription or medical documentation should be carried for medication?
Carry a signed prescription and a clinician’s letter on official letterhead that lists diagnosis, medication names (brand and generic), exact dose, frequency, total quantity dispensed and the dates covering the trip.
Original packaging and pharmacy labels: keep medicines in original containers with pharmacy dispensing labels showing patient name, prescribing clinician, date dispensed and batch/serial numbers when available.
Copies and translations: bring one paper copy and one electronic copy (photo or PDF) of all prescriptions and the clinician’s letter; translate non‑English documents into English if travelling to a country where English is required for customs/health checks.
Controlled substances and restricted medicines: obtain written authorisation from the prescribing clinician stating medical necessity; check destination rules and secure any required permits from national health authorities or embassies before departure for opioids, benzodiazepines, stimulants and similar drugs.
Quantity justification: ensure prescribed amount matches trip duration; for multi‑month supplies carry additional documentation (clinic notes or repeat prescriptions) that justifies larger quantities.
Medical devices and sharps: for injectables, insulin pens or syringes include a clinician’s letter, keep needles in a rigid sharps container during transit and retain device packaging showing model and prescription details.
Minors and caregivers: for children carry the child’s prescription, a parental/guardian consent letter signed by the prescribing clinician and proof of relationship (birth certificate or court document) if the traveller is not the legal guardian.
At security and customs: present documents readily on request; place originals in carry‑on items for quick access and store electronic backups in secured cloud or on a phone. If in doubt about national rules for specific substances, contact the destination embassy or national medicines regulator before travel.
How to present and declare medication at airport security and boarding
Present oral medication in original, clearly labeled containers at the security checkpoint; keep items in an easily accessible compartment of the carry-on and show them to the screening officer when requested.
Use concise verbal declarations at the scanner: “Personal prescription medication, original packaging” or “OTC oral medication in blister pack for personal use.” Have medication separated from other items only if asked to place them in a screening tray.
If a manual inspection is required, request a private screening area for opening containers. Allow swab testing; if containers are opened, ask the officer to reseal the contents or place them into a new sealed bag in the passenger’s presence.
For controlled or regulated substances, notify the check-in counter or gate agent upon arrival at the airport and expect additional checks. Carry only amounts needed for the trip plus a small contingency (commonly 48 hours extra) and confirm destination import rules in advance to avoid seizure.
During boarding and in-flight, keep medications accessible–stow under the seat or in an overhead locker only after boarding is complete. Inform cabin crew if administration, refrigeration or assistance is required during flight; retain dosing aids (syringes, measuring spoons) separate and visible to speed any inspection. Allow extra time at the airport to accommodate security checks.
Steps to follow if security questions, confiscates or restricts your necessary medication
If a screening officer questions or seizes prescribed medicine, immediately request a written seizure notice and ask for a supervisor review.
-
Obtain documentation on the spot
- Ask for a formal seizure receipt or incident report that includes time, date, officer name/ID and precise reason for the action.
- Photograph packaging, labels, prescription name and any barcode before handing items over, if permitted.
- Request a property tag or storage location reference if items are retained at the checkpoint or by airport security.
-
Request immediate alternatives
- Ask airport medical services or a pharmacy for a temporary supply or clinically equivalent substitution until travel continues.
- Contact the airline’s medical desk or duty manager via phone/email from the terminal to request permission for carriage under medical exception procedures.
- If a controlled substance is involved, request confirmation whether a local prescription refill is possible and which local facility can dispense it.
-
Collect contact details and incident references
- Get the name, badge number and contact details of the screening supervisor and the security office handling the case.
- Obtain an incident reference number for follow-up with the airport operator and the carrier.
-
Secure medical corroboration
- Ask the prescribing clinician to send an urgent confirmation letter or emergency electronic prescription to the airport pharmacy or airline medical desk.
- If abroad, contact the treating clinic or home physician to authorize a local refill and forward documentation by email or fax.
-
If items are confiscated, log financial impact
- Keep receipts for replacement medication, emergency consultations and any transport to obtain alternatives; these will support insurance or carrier refund claims.
- Note lost doses and any clinical consequences (missed doses, symptoms) in writing for later medical/legal records.
-
Follow formal complaint and recovery channels
- Submit a written complaint to the airport security office and the carrier within 7–14 days, attaching seizure documents, prescriptions and photos.
- Request return of retained items or a clear disposal certificate if return is refused; ask for timelines and escalation contacts.
- If unresolved, escalate to the national aviation regulator or police (for controlled substances) and provide all incident documentation.
-
Preserve evidence for reimbursement and appeals
- Store copies of all correspondence, receipts, clinical notes and incident forms in a single folder (digital and printed).
- Record dates and times of phone calls, names of staff spoken to, and any reference numbers received.
-
Prevent recurrence
- After resolution, request a written explanation of the policy applied and any procedural changes to avoid future seizures.
- Update digital copies of prescriptions and medical letters and make them accessible via email or a cloud folder for immediate forward to airport/airline staff if required.
If health is at risk because of an immediate inability to obtain replacement medication, seek urgent care from airport medical services or local emergency services and obtain a formal medical report for claims and appeals.
