Can I bring my one month prescription Xanax, in its original prescription container from my pharmacy, to Portugal ?
You may want to ask Border Patrol. Taking advice from someone here involves risk that they might take it away from you.
mciungan,
As long as it is in the original container, you will have no problems.

After living here for nine years and flying many times, I’ve never had anyone even look at medications - either in the original bottle or not.
