Doctors and researchers speaking out worldwide: 50

A growing number of doctors, researchers and therapists have in recent years been voicing their concerns about finasteride’s potential to cause persistent physical and mental side effects, known as post-finasteride syndrome (PFS), in a subset of patients. To date, the PFS Foundation has identified 50 such professionals who have published scientific findings and/or voiced opinions on causative links between finasteride and PFS. Those findings and opinions can be reviewed on our Doctors & Researchers Speaking Out page. Some of these same doctors and researchers are also members of our Medical Professionals team, counseling PFS patients and their loved ones worldwide.

If you know of any additional doctors, researchers and/or therapists who have published warnings of persistent side effects stemming from finasteride use, and/or if you would like to suggest adding a medical professional to our Medical Professionals list, please email pertinent links/names to proberts@pfsfoundation.org.

The PFS Foundation tracks global media coverage of post-finasteride syndrome on an ongoing basis. We then house significant media reports about the condition on our PFS Media Awareness page. To date, we have aggregated 268 national media reports and 45 local and/or trade media reports.
