Finasteride Use Linked to Increased Risk of Psychiatric Issues, Study Finds
A new study led by Professor Mayer Brezis of the Hebrew University of Jerusalem suggests a strong correlation between the use of finasteride, a common medication for male pattern baldness, and a heightened risk of serious psychiatric problems, including depression and suicidal thoughts. The research, recently published in the journal of Clinical Psychiatry, alleges that both the drugS manufacturer, Merck (now Organon), and the Food and Drug Administration (FDA) have historically downplayed evidence of these adverse mental health effects.
Finasteride, approved by the FDA in 1997, has generally been considered safe for treating hair loss. However, Professor Brezis argues that accumulating evidence now presents a concerning picture. “The evidence is no longer anecdotal,” he states. “We are now observing consistent patterns across diverse populations, and the consequences have, tragically, been severe.”
The study analyzed eight large-scale investigations conducted between 2017 and 2023, revealing that individuals who used finasteride were demonstrably more likely to develop mood disorders and experience suicidal ideation compared to those who had never taken the drug.
Researchers believe the mechanism behind these effects may be linked to finasteride’s inhibition of testosterone’s conversion to dihydrotestosterone (DHT). This process can disrupt the production of neurosteroids, like allopregnanolone, which play a crucial role in mood regulation. Animal studies have indicated lasting impacts on neuroinflammation and structural changes within the hippocampus, a brain region heavily involved in emotional processing.
Adding to the concern, some patients report experiencing persistent psychiatric symptoms even after discontinuing finasteride, a condition known as post-finasteride syndrome. This syndrome can manifest as insomnia, panic attacks, cognitive difficulties, and persistent suicidal thoughts, lasting for months or even years.
The FDA first acknowledged depression as a potential side effect of finasteride in 2011, and added suicidal ideation to the drug’s labeling in 2022. However, Professor Brezis points out that researchers had been raising concerns about these risks as early as the 2000s. Internal FDA documents,cited in the study,reveal classified estimates of the number of individuals affected. By 2011, the agency had recorded 18 suicides potentially linked to finasteride use, a figure the researcher believes substantially underestimates the true number. ”It wasn’t simply underreporting,” Brezis wrote, “but a systemic failure of pharmacovigilance.”
The study also criticizes the initial classification of finasteride as a cosmetic treatment, arguing that this categorization led to reduced oversight and delayed implementation of safety measures. Notably,none of the studies analyzed were funded by Merck or initiated by regulatory agencies.
“This wasn’t a matter of life or death driven by medical necessity,” Brezis emphasized. “It was about hair.”
Organon, the current marketing authorization holder for finasteride, stated that “nothing is more vital […] than drug safety,” but confirmed it has not independently conducted new safety studies. The FDA reportedly took five years to respond to a petition requesting a “black box warning” – the most stringent type of drug warning – ultimately opting to simply add a mention of suicidal ideation to the drug’s facts leaflet.
Based on his findings, Professor Brezis recommends a reevaluation of drug approval and monitoring protocols, and a temporary suspension of finasteride for cosmetic use until its safety profile can be thoroughly reassessed.
“For many,” Brezis concludes, “these changes come too late.” the article is dedicated to a man who, seeking to improve his appearance, began finasteride treatment and later experienced a rapid and severe psychiatric decline, ultimately leading to his death by suicide months later.
