Medications crossing borders: Drugs to watch for and where to locate accurate sources of guidance on medication transportation across countries

Author(s):  Dr Sherilyn Houle

A travel consultation involves collecting a patient’s medical history, including their prescription, non-prescription, and recreational drug use. In doing so, clinicians should be aware of those that may have unique considerations impacting their transport and use abroad. Traveling with a banned product or with inadequate documentation can result in travel delays, confiscation of the product, or even arrest.

The “Traveling with Prohibited or Restricted Medications” chapter of the CDC Yellow Book provides guidance on how to identify and potentially mitigate challenges related to traveling with medications.¹ Drug classes to pay particular attention to include narcotics, benzodiazepines or other sedatives, stimulants, anabolic and androgenic steroids, and pseudoephedrine, among others.

For information on travel with narcotics or psychotropics, the International Narcotics Control Board website can be consulted as a starting point, as it provides information on travel with medications to over 100 countries.² However, be advised that not all drug classes subject to restrictions are reported, and the information posted may be outdated (the date of the report is provided for each country). Users are advised to contact the intended country’s embassy or consulate to verify current restrictions and regulations.

Unfortunately, no single comprehensive resource on traveling with medications exists. Advise travelers to consult official government websites for guidance and to avoid online articles, discussion boards, or blogs for this information, as they may be inaccurate or outdated. A traveler's unawareness of regulations is not a valid defense against the consequences of improper transport of medications, which can be serious. If in doubt, reach out!
