Documented Uses

• Medication: Treatment of benign prostatic hypertrophy
• Use (kg; approx.) in Germany (2009): >250
• Consumption (g per capita; approx.) in Germany (2009): 0.00305
• Consumption (g per capita) in the USA (2002): 0.00143
• For the treatment of symptomatic benign prostatic hyperplasia (BPH) in men with an enlarged prostate to: Improve symptoms, reduce the risk of acute urinary retention, reduce the risk of the need for surgery including transurethral resection of the prostate. Also used for the stimulation of regrowth of hair in men with mild to moderate androgenetic alopecia (male pattern alopecia, hereditary alopecia, common male baldness).
• Finasteride is a 5-alpha reductase inhibitor used to treat symptoms of benign prostatic hypertrophy and male pattern baldness. Finasteride is associated with a low rate of transient serum aminotransferase elevations, but has yet to be linked to instances of clinically apparent, acute liver injury.
