I am flying Croatia-Japan and I was curious how to go about bringing medication on board. I'm taking my prescription allergy medicine, which is basically just bilastine tablets and fluticasone furoate nose spray. They're in the original packaging.

Do I need a doctor's note? Do I carry it in my carry-on baggage or somewhere else?
