I'll be taking an overseas trip (14+ hrs) and I will need to take my meds with me. They must be inside an insulin bag, to keep it cool, and in my Handgepäck but I don't want it to be opened at the security checkpoint as to keep the temperature constant, is it enough to show the Rezept/prescription?

Asking for actual experiences, or from people developing biologicals, please.
