I was on a "banned" medication when I took my physical. FAA in OKC
required me to be off for three months, then have a letter written by
my primary care doctor confirming that I'd had no ill effects from
being off the med. After that, my medical was issued. In my opinion,
if you go off the medication, there is no reason to mention to your AME
that you were on it...the form asks for current meds, not historical
meds.
Good luck. CPW
