Looing for advice, I am entering aviation school in the fall and I received my 2nd class medical certificate but then shortly after received a letter from the FAA asking for more information within 60 days on my use of Accutane, that my medical was not denied they just wanted more info. I had my dermatologist write a letter stating that I had taken for 6 months from Aug 2018 to Feb 2019 and that I had discontinued and no longer take it. Is this enough or do I still need an eye test or psych eval. or anything? Also, how long does it normally take the FAA to respond? Thank you!
