The answer is - it depends. Don't take what is on the TSA website "approved" lists as gospel because I don't think a lot of the screenerNazis bother to read their own regulations. I have been hassled repeatedly about an injectible medication I have to have, which I keep it its factory-issued container, along with a refill with the prescription pasted on it. Still ... I will never forget the TSA dimbulb who had me not only take everything out, but completely disassemble it, and then was going to touch the needle to see if it was sharp and therefore a “weapon.” I politely informed her that I had an aversion to blunt, bent, contaminated needles and unless she was thinking of using it on herself, she had about 5 seconds to put it back. I barely made my plane.
