So apparently, the label on the bottle is considered the "prescription" for their purposes.

Here is the location information for CBP at U.S. ports of entry (and departure). I'm going to try showing up at the SFO site the day before my flight with boarding pass in hand for my 7:30AM flight and see what happens. I'll report back.
