Traveling With Prescription Medication

Medication is the one item where the packing rule and the law point in the same direction: keep it in your carry-on, in its original labeled container, in the quantity you need plus a margin. The complication is that a medicine which is ordinary in the United States can be restricted or prohibited somewhere else, and the traveler is expected to have checked. Of the 211 destinations the State Department publishes, 30 address medication in their local laws.

What You Need to Know

Three separate rules apply to the same bottle, and they come from different places.

The airline rule

Medication belongs in the cabin. It is exempt from the usual liquid limits when it is medically necessary, though you should expect to declare it at screening, and it should be reachable rather than buried. This is the same reasoning as for anything else irreplaceable: a checked bag that arrives two days late is an inconvenience for clothes and a genuine problem for a daily prescription.

The destination’s rule

This is the one travelers miss. The CDC states plainly that some countries have restrictions on what medications you can bring, and directs travelers to check with the U.S. embassy for the country concerned. The categories that most often cause trouble are stimulants prescribed for attention disorders, strong painkillers, some sleep and anxiety medications, and preparations containing codeine or pseudoephedrine. Some countries require an import permit obtained in advance; some cap the quantity at a stated number of days; a few prohibit a drug outright regardless of prescription.

The consequence of getting this wrong is not usually a fine. It is confiscation at the border, which leaves you abroad without a medicine you need, and in the more serious cases it is a criminal matter.

The documentation rule

Carry the prescription or a letter from your doctor listing each medication by its generic name, the dose and the condition it treats. Generic names matter because brand names vary by country and a pharmacist abroad may not recognize yours. That letter is also what makes replacement possible if a bag is lost.

What to Do Before Your Trip

• Check your destination’s rules for every prescription, well before departure.
• Ask your doctor for a letter with generic names, doses and conditions.
• Request an early refill if the trip runs past your next one.
• Pack it all in the carry-on, in original containers, split across two bags if traveling with someone.
• Photograph the labels and the letter and store them where a lost bag cannot take them.

Important Considerations

Quantity is regulated in some places, typically as a supply for a stated number of days, so a traveler carrying a year of a maintenance drug for a two-week trip can create a problem that a traveler carrying three weeks would not. Bring a margin, not a stockpile.

Time zones complicate dosing schedules, and for most medicines an hour or two of drift is unimportant. For a few, including insulin and some hormonal and anticoagulant medications, it is not. Ask your doctor how to handle the shift before you leave rather than working it out on the aircraft, and consider the CDC’s general advice on preparing a travel health kit at the same time.

Refrigerated medication needs a plan of its own: an insulated case, an understanding of what the destination’s power supply is like, and a conversation with the airline in advance if it must be kept cold in flight.

Tips for Group Travelers

• Ask privately and in writing what medications people carry and what they are for.
• Never carry someone else’s prescription. The label must match the passport.
• Warn the group about destination restrictions early enough for them to act on it.
• Know who carries an epinephrine autoinjector or an inhaler, and where it is.
• Build a pharmacy stop into the itinerary for a long trip, and know where one is.

Common Mistakes to Avoid

• Putting medication in checked luggage.
• Repacking into an unlabeled pill organizer with nothing to identify the contents.
• Assuming a U.S. prescription is accepted everywhere.
• Bringing exactly enough, with no margin for a delay.
• Carrying a controlled medication without checking the destination’s rules.

Frequently Asked Questions

Can I take my medication through airport security?

Yes. Medication is permitted in the cabin and medically necessary liquids are treated as an exception to the usual limits, though you should expect to declare them and have them inspected. Keep them accessible rather than at the bottom of the bag, and in their labeled containers so that what they are is obvious.

How do I find out whether my medication is legal at my destination?

The CDC advises checking with the U.S. embassy for the country you are traveling to, which is the authoritative route because rules are set nationally and change. Some countries publish a list of controlled substances and a permit process; others answer only on request. Do this weeks ahead, since a permit takes time.

Should I use a pill organizer?

Use one for daily convenience if you like, but carry the original labeled containers as well. The label is what proves the medication is prescribed to you, and a border officer looking at loose tablets in a plastic case has no way to establish that.

What if I run out or lose my medication abroad?

Contact your insurer’s assistance line first, since many can locate a provider and arrange a replacement prescription. Your doctor’s letter with generic names is what makes this straightforward. The nearest U.S. embassy or consulate can also help you find local medical care, though they cannot supply medication.
