My friend recently flew to Mexico with that sort of thing (she has liver issues and no spleen, and takes immunosuppressives, and all sorts of pills), and had no problems.
However, she says that the NEXT time she flies, she's taking copies of prescriptions with her, because they COULD have asked her questions about all the pills, and once she realized she had no proof that all those drugs were OK and for her, she realized she could have gotten into trouble. But none of her medications are liquid, so I'm not even sure she took them out of her carryon for the xray machine...
Thanks! I have to see all my dr.'s in the next week so will photocopy my prescriptions to take with me.
