Men Home > What Is Finasteride Used For?

How Does Finasteride Work?

Finasteride works by blocking the conversion of testosterone into DHT (dihydrotestosterone), which decreases the amount of DHT in the body. Since DHT is important for enlargement of the prostate, using finasteride to decrease DHT levels can treat an enlarged prostate. Finasteride helps to shrink the prostate in most men, helping with their BPH symptoms.
 
DHT is also important for male pattern baldness. By decreasing the amount of DHT, finasteride can help stop hair loss and regrow hair.
 

Is Finasteride Used for Children?

Finasteride has not been adequately studied in children and is not approved for use in children. Because finasteride affects certain hormones, the benefits of finasteride in children may not be worth the risks.
 

Is Finasteride Used Off-Label?

On occasion, your healthcare provider may recommend finasteride for treating something other than the condition(s) discussed above. This is called an "off-label" use. At this time, there are several off-label finasteride uses, including:
 
  • Treatment of prostate cancer after surgical removal of the prostate
  • Treatment of hirsutism (excess body and facial hair) in women
  • Treatment of female pattern baldness.
