5-Alpha-Reductase Inhibitors

Agents in this class decrease dihydrotestosterone serum levels and may be beneficial to hidradenitis suppurativa.

Finasteride (Proscar)

Finasteride inhibits steroid 5alpha-reductase, which converts testosterone into 5alpha-dihydrotestosterone (DHT), causing serum DHT levels to decrease. All skin tissue predominantly contains type 1 isoenzyme, and the genital region contains type 2. Finasteride has been effective in treating hirsutism. Finasteride might be a suitable additive therapy for refractory female hidradenitis suppurativa cases.
