Doctors and researchers speaking out worldwide: 30

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 30 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
