I am a U.S. citizen. I need to travel from the U.S. to Turkey with my wife and daughter and stay there for 2 weeks (we meet with our relatives from other countries there). I need to take prescription medications (controlled substances: Adderall/Dextroamphetamine and Ritalin/Methylphenidate), prescribed to me by my doctor in the U.S. for ADHD. I only need to take the amount required for my personal use for 2 weeks. They are in the original packaging with labels printed by the pharmacy, containing my full name, the doctor's name, and the name of the medication.
What steps should I take to legally and safely bring my prescription medications to Turkey? Do I need anything other than pharmacy-printed labels on the bottles and a letter from my doctor in English? Should the doctor's signature be notarized or certified somehow? Do I need to get pre-approval from Turkish authorities to bring my medications there?
