Is finasteride safe?

>”The target of finasteride, 5AR, converts deoxycorticosterone into dihydrodeoxycorticosterone (DHDOC), progesterone into dihydroprogesterone (DHP), and testosterone into dihydrotestosterone (DHT)[4]. Consequently, inhibiting 5AR also inhibits the synthesis of the neurosteroids androsterone, androstanediol, THDOC, allopregnanolone, and isopregnanolone.”

Surely inhibiting all of these long term would cause problems, no?
