I'm a 65 YO guy with quite a few health problems which require that I have an array of prescriptions drugs when I travel. Recently my pharmacy, CVS, has switched over to a much larger bottle - their minimum size is now 20 drams and a 2 week supply of most of my drugs doesn't even cover the bottom of such a bottle! More to the point, because of the number of prescriptions I have, a full set of these huge bottles takes up too much space in the container I carry my drugs and toiletries in, and wastes a LOT of space! (as well as contributing extra plastic to the waste stream)

My Question: I've seen conflicting information about whether the drugs have to be in the original container. My pharmacy has offered to print up stick-on prescription labels so I could put my pills in small zip-lock bags, each with its own official pharmacy label. Is that sufficient to get in and out of most countries?

Thanks in advance.
