When traveling to France with prescription medication in 2026, you should carry the medicine in its original packaging with the pharmacy label clearly visible. You are generally permitted to carry a supply for your personal use corresponding to the duration of your stay (up to a three-month supply for standard meds). You must carry the original, valid medical prescription signed by your doctor, preferably with the generic name of the drug listed in case of an emergency. For medications classified as narcotics or psychotropics (like certain painkillers or ADHD meds), the rules are stricter: you can only bring a 28-day supply, and you must have an official certificate from your national health authority if you are coming from a non-Schengen country. Always keep your medication in your carry-on luggage to avoid issues with lost checked bags or temperature fluctuations in the cargo hold.
