The FAA's MedGuide lists finasteride (Proscar, Propecia) as allowed, for alopecia (hair loss), benign prostatic hypertrophy (BPH) or polycystic ovarian disease (PCOS) [OL], with a wait of 48 hours after the first dose and none after later doses or after the final dose, used as prescribed; for PCOS, the entry under that use carries the FAA's PCOS worksheet as well.

The MedGuide defines allowed as acceptable for use while performing flight or safety-related duties, provided the condition is stable/aeromedically acceptable and no adverse side effects are present, and says wait times are not determined solely by the medication: an extended observation period may be required to verify clinical stability of the condition.
