Whenever I travel, In addition to my prescribed medications, I like to bring a small supply of basic medications just in case you need them or they are not readily available wherever you are traveling to (try finding Benadryl in the middle of Croatia). Including: Advil, Pepto, Imodium, Benadryl, Emergen-C, Sleeping Aid, etc. I also keep a couple of Bandaids with me too.
