Travelling With Medication

Carrying medication across a border is a paperwork exercise as much as a packing one. The rules that apply are those of the country you are entering, and a prescription that is routine at home can be a controlled substance elsewhere.

Carry It, Do Not Check It

Medication belongs in your cabin bag. Checked luggage gets delayed, and a missed dose on a long flight turns into a medical problem rather than an inconvenience. The cabin also stays closer to room temperature, which matters for insulin and for anything that should not freeze in a cold hold.

Keep everything in its original packaging with the pharmacy label showing your name, the drug and the dose. Loose tablets in a weekly organiser tell a customs officer nothing about what they are or who they belong to, and that is when questions start.

Ask the pharmacy for a printed list of your medicines showing the generic name, and keep it with the doctor's letter rather than in a bag that goes into the hold.

Documentation That Helps

Carry a copy of your prescription and a letter from your doctor on letterhead naming the drug, the dose, the condition it treats and the dates you will be away. Controlled drugs sometimes need an import permit arranged in advance, and those applications can take weeks to process.

If you need needles, syringes or an injectable, ask the doctor to state that in the letter. Keep the quantity consistent with the length of the trip, because an amount that looks commercial invites a decision you do not control.

Where a permit is required, the officer may count what you carry against the quantity declared. A mismatch causes trouble even when the total is small, so declare the exact number of tablets or ampoules.

• Prescription copy - Matches the packaging and carries your name and dose.
• Doctor letter - On letterhead, naming drug, condition and travel dates.
• Import permit - Required in advance for controlled drugs in some countries.
• Needle declaration - States why syringes are needed and how many you carry.

Check The Destination's Rules

Some medicines sold freely in one country are controlled or banned in another, including certain painkillers, stimulants and sedatives. The arriving country decides what is legal on its territory, whatever your prescription says. Check its embassy, health ministry or customs site for each drug you take, and repeat the check for every country on the route.

Transit counts. A connection where you clear customs puts you inside that country's rules even if you never leave the terminal. Quantity limits for personal use are usually expressed in days of supply, and they differ from one country to the next.

Save the emergency number for the destination and the address of a clinic near where you are staying. A pharmacist abroad can advise you, but controlled medicines usually need a doctor to prescribe.

• Controlled drugs - Painkillers, sedatives and stimulants, restricted in many places.
• Transit country - Its rules apply when you clear customs on a connection.
• Days of supply - The usual way personal use limits are written.
• Customs site - The destination's own published list of restricted medicines.

Heat, Time Zones And Supply

Insulin and some other drugs need steady cool storage. A cool bag with gel packs holds a stable temperature through a flight, and gel packs fall under liquid rules, though medically required ones are usually exempt with documentation. Ask the airline what it needs before the day of travel.

Set alarms on the destination's clock so doses are not missed or doubled around a time change. When you are crossing many zones, ask your doctor or pharmacist how to shift the timing rather than improvising a plan mid flight.

Do not rely on ice to keep a drug cold, because ice melts and refreezing damages some formulations. An insulated pouch with gel packs and a small thermometer is easier to manage than improvised cooling, and it survives a long connection.

If Something Goes Wrong

Split the supply between two bags when you travel with someone, so a lost bag does not leave you with nothing. Write down the generic name as well as the brand, because the same drug is sold under different names abroad and a pharmacist cannot match a brand they do not stock.

If you run out, a local doctor can usually issue a prescription after an examination, and your travel insurer's assistance line can point you to a clinic. Keep the receipts from any treatment abroad, since a claim needs them and the insurer's deadline is often shorter than people assume.

Check that your policy covers the conditions you already have, since a claim linked to a pre-existing condition is the most common reason travel claims are refused. Answer the medical questions accurately: an insurer that later finds an undisclosed condition can cancel the policy and refuse the claim. Describing a trip or an illness untruthfully to an insurer voids the cover, and to a border officer it is an offence.

• Split supply - Two bags, so one loss does not remove everything.
• Generic name - How a foreign pharmacist identifies the same drug.
• Local prescription - Issued after a consultation, usually at short notice.
• Treatment receipts - Needed for a claim, with a deadline attached.
