What to know about Finasteride
How it Works
Finasteride, also sold under the brand name Propecia®, has been clinically tested and FDA approved for the treatment of male pattern baldness by blocking the body’s production of the male hormone dihydrotestosterone (DHT). Blocking the body’s production of DHT has also shown positive outcomes for patients dealing with BPH. Finasteride was FDA approved for BPH under the brand name Proscar and the generic is available in 5mg tablets.
Who is it for?
Finasteride is in a class of medications called 5-alpha reductase inhibitors. Finasteride therapy is usually prescribed to treat male pattern baldness but also has been found effective for treating BPH.
Studies indicated 66% of men have shown increased hair growth from using Finasteride.
