TLDR Finasteride for hair loss may cause painless bleeding in urine and semen.
This case report discusses a 38-year-old male who experienced painless hematuria and hematospermia while taking finasteride (Propecia tablets) for androgenic alopecia at a dose of 1 mg/day. The bleeding was linked to finasteride use as it occurred 2-3 days after use and stopped upon discontinuation of the drug. The patient was subjected to urological examination, laboratory investigations, and radiological imaging to identify the probable cause of bleeding. It appeared the bleeding was most probably of prostatic origin in the absence of obvious underlying pathology. The report suggests that clinicians should pay attention to this adverse effect in order to properly identify its frequency and severity.
