United States: Transportation security allows prescription medications in carry-on; prescription liquids larger than 100 ml are exempt from the 3.4 oz limit when declared for inspection. Present medications separately for X-ray screening and state the medical nature of the items to the screening officer.
Documentation: retain the original container showing traveller’s name, drug name (generic and brand), dosage and quantity; add a printed prescription and a brief physician note outlining diagnosis and duration of therapy. Provide translated documents for destinations whose official language differs from the prescription language.
Quantity and controlled substances: many jurisdictions permit a 30–90 day supply but rules vary. Preparations containing opioids, codeine, tramadol, certain stimulants or benzodiazepines often require an import permit or prior authorization; failure to present appropriate paperwork can lead to seizure, fines or criminal charges.
Packaging and administration devices: tablets and capsules should remain in pharmacy bottles; liquid analgesics must be declared and presented separately. Injectables, syringes and insulin should be accompanied by a prescription and, where possible, a physician’s letter; carry spare batteries for pumps and store devices in carry-on.
Before departure, verify airline policy and consult official government or embassy sources at origin, transit and destination for prohibited substance lists and permit procedures; obtain written approvals for controlled medicines when required and keep digital and printed copies of all medical paperwork.
How many over-the-counter tablets or capsules are allowed in carry-on?
Limit solid over-the-counter tablets or capsules to a 90-day supply per medication when packed inside carry-on; this amount aligns with common airline recommendations and avoids unnecessary questions at security or border control.
Specific quantity rules
United States (TSA): no fixed numeric limit for solid medicines in carry-on, but expect screening and keep prescription labels when transporting larger amounts. European Union / Schengen: personal-use quantities generally accepted; 30–90 days is typical. Australia and New Zealand: usually permit up to a 90-day supply for non-controlled medicines; controlled substances often require permits. Several countries restrict controlled analgesics to 30 days or less and demand prior authorization.
Packing and documentation
Keep tablets/capsules in original labelled packaging listing ingredient, strength and dosage. Carry a prescription or doctor’s note stating diagnosis, dosage and duration for any supply exceeding one month. For controlled substances (codeine, tramadol, oxycodone, morphine and similar), obtain written permission from the destination health authority if required and carry an official prescription on clinic or hospital letterhead. Record the exact pill count per medication and present documentation at security or customs on request.
Liquid or gel analgesics and the 100 ml / 3-1-1 rule
Medically necessary liquid or gel analgesics are exempt from the 100 ml/3-1-1 restriction in cabin baggage if declared at the security checkpoint and presented for separate screening.
Keep products in original, clearly labelled containers and carry a prescription or physician’s note showing the generic name, strength, dosage, quantity required and travel dates; pharmacy dispensing labels are helpful.
Declare items to security staff before screening; present them outside the clear 3-1-1 bag for inspection. Expect container opening, swabbing or additional X‑ray screening; allow extra time at the checkpoint.
No fixed maximum volume is imposed by TSA or EU aviation security–authorities apply a “reasonable quantity” standard. Quantities matching the trip duration (plus a short buffer) are usually accepted; large commercial volumes may be refused.
Formulations containing controlled ingredients (for example opioids or codeine) often require advance permission from the destination’s health authority or an official import permit; airlines and some countries demand original prescriptions, translated documents or written permits–verify prior to travel.
If admissibility is uncertain, move surplus liquid/gel analgesics to checked baggage only after confirming destination and airline regulations; when in-flight access is required, retain declared items in cabin baggage and ensure quick access.
Confirm rules with the airline and relevant security agencies before departure; keep both paper and digital copies of prescriptions and prescriber contact details for presentation if requested.
Do prescription analgesics require original packaging and a doctor’s note?
Recommendation: keep prescription analgesics in original pharmacy containers bearing the traveller’s name and dispensing details, and carry a physician’s letter on official letterhead that lists generic drug names, strengths, dosing schedule, total quantity for travel and the prescriber’s contact information.
Documentation checklist
Must-have items: original labelled container; printed prescription; physician’s letter with passport number or full name and travel dates; photocopies and a phone image of all documents; pharmacy receipt or dispensing label showing date and quantity. Translate the physician’s letter into the destination language if possible.
Controlled substances and official approvals
Opioids, benzodiazepines and stimulants (examples: morphine, oxycodone, tramadol, diazepam, alprazolam, methylphenidate) commonly face tighter rules: some countries require an import permit, prior approval from national health or drug-control agencies, or a stamped prescription from an embassy. Check destination regulations well before travel and request any required letters or permits from the prescriber or national authority.
Store medications in an accessible cabin bag or a secure waist pouch for quick inspection (example: best mountain bike waist packs). Keep pill counts consistent with labels; separate travellers’ supplies into individually labelled containers.
If customs or security officers request verification, present original labels plus the physician’s letter; if a language barrier exists, present a translated summary and contact details for the prescribing clinician. Obtain written permits or stamped approvals before departure when required by the destination authority.
How to present and declare analgesics at airport security checkpoints
Place oral tablets, capsules and topical or liquid analgesic medications in a clear, resealable plastic bag and present that bag separately to security officers before screening begins.
At the security checkpoint
Inform the screening officer that medical medications are in the tray or on the conveyor. Keep prescription bottles with pharmacy labels, blister packs or original boxes visible; loose pills in unlabelled containers invite secondary inspection. Large liquid or gel medications should be removed from cabin baggage and placed on the belt for X-ray as a separate item if requested by staff.
Documentation and practical steps
Carry a printed copy of the prescription or a letter from the prescribing clinician for controlled substances and opioids; pharmacy labels are acceptable for over-the-counter formulations. Allow extra time at the checkpoint during peak hours. If a medication requires refrigeration or injection, inform airline staff at check-in and security staff at screening.
Item | How to present | Documents to carry |
---|---|---|
Tablets / capsules (OTC) | In original blister pack or labelled bottle; placed in clear resealable bag and shown separately | Pharmacy label or purchase receipt recommended |
Prescription oral meds (including opioids) | Original labelled container displayed to officer; keep dose schedule accessible | Printed prescription or clinician letter; photo ID |
Liquids / gels (medicinal) | Placed separately on the belt when requested; clearly labelled containers | Prescription or clinician note for volumes larger than carry-on liquid limits |
Injectables / refrigerated meds | Inform staff at check-in and screening; carry cold pack within cabin baggage | Clinician letter, prescription, and storage instructions |
For inter-airport differences: US screening allows medically necessary liquids in quantities greater than the usual limit when declared; EU and UK checkpoints accept medicinal volumes if declared and labelled, though additional screening (hand inspection or swab) may occur. Passengers travelling with controlled substances should verify destination-country import rules before departure.
Keep a small clean-up kit for accidental spills; for guidance on carpet incidents, consult how to clean cat puke off carpet.
Rules for carrying controlled opioids across international borders
Obtain an official import/export permit from the national narcotics authority before traveling with Schedule II opioids; a prescription alone is frequently insufficient.
- Immediate checklist:
- Confirm legal status and scheduling of the specific opioid at origin, destination and all transit countries (scheduling varies by jurisdiction).
- Request from the prescriber a signed medical certificate specifying generic name, formulation, strength, daily dose, total quantity and treatment duration in days.
- Apply to the national narcotics control authority for an export or personal-use permit if required; allow 4–8 weeks for processing in many countries.
- Obtain translated and, where required, legalized (apostille or consular legalization) copies of prescription and medical certificate.
- Quantities and limits:
- Commonly accepted maximum without special permit ranges between a 30‑day and 90‑day supply; some states demand a permit regardless of quantity.
- Certain substances classified as lower‑control in one country (e.g., tramadol) are Schedule II/III elsewhere; calculate total morphine milligram equivalents (MME) to clarify control level.
- Permits, forms and authorities:
- Contact the national narcotics office or ministry of health in origin and destination; examples: DEA (United States), Home Office/MHRA (United Kingdom) – local authority names differ.
- Ask whether a national import permit, a medical certificate for controlled substances or an INCB‑related document is required for personal carriage.
- Confirm whether transit countries require advance approval even when remaining airside.
- Practical measures:
- Keep paper and digital copies of permit(s), prescription and medical certificate; present originals on request.
- Plan contingency: identify how to obtain replacement medication at destination and find local prescribers in case permits are refused.
- Expect inspection, possible temporary seizure or detention if documentation is absent or authority rules prohibit the substance.
- Risk management:
- Do not rely on airline staff to advise about legal import/export rules; airline policy and national law differ.
- When in doubt, consult the destination country’s embassy or consulate and the origin country’s narcotics regulator before departure.
