Hi,
If this is a great concern for U, I think U should contact USMLE org. I am sure someone can answer that question for U, and if not perhaps direct u to someone that can just to be sure. (If u do find out, please do let us know,thanx)
If you are enrolled in Kaplan, or Falcon or a major review course maybe they can accurately find out for U.
But in reference to the question of FA.....
I would say u will find Rx on ur test that r not in FA.
FA has a great amt of the drugs, but not absolutely ALL.
In regards if they discontinue a Rx, Im assuming that it is a process before they get rid of that one question, therefore it doesnt hurt to just memorize that extra RX.
Good Luck in ur studies
