What is Finasteride Syndrome?

Finasteride Syndrome, also known as Post-Finasteride Syndrome (PFS), is a set of severe and sometimes persistent side effects that some individuals experience after discontinuing the medication finasteride. This syndrome is primarily reported in younger males who take finasteride to address hair loss. Key symptoms include:

• Significantly reduced libido
• Erectile dysfunction
• Depressive symptoms, including severe depression and suicidal thoughts

Dr. Huberman explains that finasteride has been used for many years, particularly at higher doses for prostate issues. However, PFS has only recently become a topic of concern for those using lower doses for hair loss. The exact cause of PFS is still under investigation, but it appears linked to the role of dihydrotestosterone (DHT) in brain and genital development beyond puberty, possibly affecting brain regions like the hypothalamus even into one's twenties and thirties 1 2.

Dr. Michael Eisenberg, a urologist, notes that while some men recover from these symptoms after stopping finasteride, a subset of individuals experiences persistent dysfunction. This ongoing impact underscores the need for careful consideration before using finasteride, especially for cosmetic purposes, due to the potential for long-lasting effects on sexual health 3 4.
