@jeffmarc It's like the others have said, it's not as blanket as Drug name is OK or not, but, and this is FAA only! Here's what one of the largest medical certfication consulting companies will tell you...

Orgovyx = ALLOWED, Underlying Condition Likely Requires Special Issuance

Lupron = ALLOWED; Requires 2 weeks observation after initial administration (For prostate cancer likely requires Special Issuance)

Firmagon = Allowed but underlying condition likely requires Special Issuance after 30 day trial

Eligard = Allowed but Condition likely requires Special Issuance

The FAA guide to Aeromedical examiners (AME) indicates that the Aeromedical Examiners in the field (doctors who qualify for this) Should not issue a medical for anyone being treated for Prostate Cancer with medications.

Here's what the guide actually says in chart form, title is DO NOT ISSUE (DNI) MEDICATIONS
CANCER TREATMENTS Including many chemotherapy, radiation therapy, and immunotherapy medications, whether used for induction, maintenance, or suppressive therapy.

What this means is the applicant, with the help of his AME, has to file for a Special Issuance (SI) directly to the FAA's Aeromedical Branch in Oklahoma City. They look at all your documentation and make a determination, often after asking for more documentation....

I'm told the 7 mos I waited was a VERY quick determination to issue based on fellow pilot's experiences.

I had the same experience initially as @gmarkos1 , I stopped flying on my own, had the RARP when I had a note from my surgeon telling me it was okay to work, I applied for a medical, since my doc said I was good to go, I just went back to work. I wasn't on any meds at the time.

It was the chemical recurrence that made me ineligible until the SI was issued. The SI wouldn't be revoked until I hit .17 PSA according to my AME. How they came up with that arbitrary number is a mystery to both of us.

Clear as mud? Still confuses me.
