Using finasteride for hair loss is like shooting at sparrows with cannons.
Using finasteride for hair loss is like shooting at sparrows with cannons. The drug.…blocks not only the super hormone but also other hormones that affect thinking and psyche, mood and emotions.

We wouldn’t recommend that any man take [finasteride], especially not young men.
We are certainly very cautious, because we see the side effects. We wouldn’t recommend that any man take [finasteride], especially not young men. The longer they take it, the greater the risk of experiencing persistent side effects, including after they’ve stopped.

For the first time, we demonstrate a tissue-specific methylation pattern of SRD5A2 promoter in PFS patients.
For the first time, we demonstrate a tissue-specific methylation pattern of SRD5A2 promoter in PFS patients [which] could represent an important mechanism of neuroactive steroid levels and behavioral disturbances previously described in PFS… The SRD5A2 promoter was more frequently methylated in the CSF of PFS patients compared to controls (56.3 versus 7.7%).

FDA is concerned that use of finasteride by pediatric patients may pose long-term safety risks.
Finasteride inhibits Type II 5(alpha)-reductase, which metabolizes testosterone to the potent androgen 5(alpha)-dihydrotestosterone. FDA is concerned that use of finasteride by pediatric patients may pose long-term safety risks regarding growth, development and sexual function.

SOMERSET, N.J., Jan. 6, 2014 – The number of nations that logged onto the Post-Finasteride Syndrome Foundation website rose 29 percent in 2013, according to Google Analytics. In all, users in 120 countries outside the United States—or 61 percent of the world (as defined by the 195 nations recognized by the U.S. Department of State)—accessed […]
SOMERSET, N.J., Oct. 29, 2013 – The Post-Finasteride Syndrome Foundation is reminding PFS patients to report all persistent side effects to the FDA MedWatch program. MedWatch is the U.S. Food and Drug Administration’s system for detecting safety-hazard signals for pharmaceutical products and medical devices. If a signal is detected, the FDA can issue safety alerts, […]
SOMERSET, N.J., Aug. 21, 2013 – The Post-Finasteride Syndrome Foundation today announced the funding of a second major clinical study on post-finasteride syndrome (PFS), this one at Baylor College of Medicine (BCM) in Houston, Texas. Titled “Genetic and Epigenetic Studies on Post-Finasteride Syndrome Patients,” the research is being led by Mohit Khera (right), MD, MBA, […]
August 7, 2013 Dear Friends: The PFS Foundation is seeking information about patients who have taken finasteride or dutasteride, and who have attempted suicide or who have completed suicide. This is an area of active research interest and researchers are seeking to obtain medical records and other relevant material for such patients. To […]
Aug. 4, 2013 Dear Friends: When we incorporated the Post-Finasteride Syndrome Foundation in July 2012, our mission was clear: To fund research on the characterization, underlying biologic mechanisms and treatments of PFS while raising public awareness of this often life-altering condition afflicting thousands of men the world over. Now, on the occasion of our one-year […]
