Finasteride (Proscar), dutasteride (Avodart), and dutasteride in combination with tamsulosin are approved to improve symptoms of an enlarged prostate gland (benign prostatic hyperplasia or BPH). Proscar and Avodart are also approved to reduce the risk of urinary retention or surgery related to an enlarged prostate. Finasteride (Propecia) is approved to treat male pattern hair loss.
