or declare it at all?
It's a tiny delicate vial which I do not want bouncing around with the toothpaste etc in the bag, so I am hoping it is OK to box it up and leave it among my clothes in the carry-on.
Thanks.

Since you mentioned syringes in your first post I'm guessing you have them in some type of container like a Frio or such.
If it is a liquid, medicine or not, it has to be declared. If in a medical kit just take the kit and declare that. If the vial is strong enough to go in your 3.1.1 KHIAI Freedom baggie then put it there if that works best.
There have been many reports of people not removing their 3.1.1. bag. If you don't and get an Ahole screener your day is likely to only go down hill.
