It's best for any type of travel to keep the medication in the original pharmacy bottles with the pharmacy label on them. Since many medications used to treat ADHD are controlled medications, some travelers feel better if they carry a letter from their child's doctor indicating why the medication is prescribed.

Yes, you can travel with ADHD medication (such as Ritalin, Concerta, or Adderall), but because these are "controlled substances" (stimulants), you must follow strict legal protocols. In 2026, you must carry a copy of your prescription and a signed letter from your doctor stating that the medication is for personal use. Always keep the medication in its original pharmacy packaging with your name clearly visible on the label. If you are traveling to a Schengen country within Europe, you may need a specific "Schengen Certificate" signed by your doctor and the local health authority. For destinations outside Europe, especially in Asia (like Japan or Singapore) or the Middle East, rules are extremely strict; some ADHD medications are outright illegal without prior government "Import Permission." Always check the official website of the embassy of your destination at least 4 weeks before your trip to ensure you aren't inadvertently carrying a prohibited substance.
