SOMERSET, N.J., April 18, 2017 – Post-finasteride syndrome (PFS) patients suffer from altered levels of critical brain-function regulators, including neuroactive steroids, according to a new clinical study published in The Journal of Steroid Biochemistry and Molecular Biology. Titled Neuroactive Steroid Levels and Psychiatric and Andrological Features in Post-Finasteride Patients, the three-year study also uncovered evidence […]
SOMERSET, N.J., March 9, 2017 – More than one percent of young men who took finasteride for 206 days or longer developed persistent erectile dysfunction (PED) that lasted an average of 4.2 years after drug discontinuation, according to a new study published today in PeerJ. In all, researchers examined the electronic medical records (EMR) of […]
SOMERSET, N.J., Sept. 29, 2016 – Men who experience persistent sexual dysfunction after discontinuing finasteride have “neurobiological abnormalities,” suggests a new study published in The Journal of Clinical Endocrinology & Metabolism. Among those abnormalities is neural circuitry that overlaps with functional abnormalities identified in men suffering from “major depression.” Titled Characteristics of Men Who Report […]
SOMERSET, N.J., Sept. 21, 2016 – The Post-Finasteride Syndrome Foundation has launched a program to connect PFS patients with one another for mutual support. Any PFS patient or family member of a PFS patient who would like to participate should download the PFS Patient Support form, complete it and email it back to firstname.lastname@example.org. Due […]
Aug. 4, 2016 Dear Friends: I began last year’s annual address by letting you know how encouraged I was that the National Institutes of Health had not only added PFS to its Genetic and Rare Diseases Information Center but linked to our website. Now I’m equally encouraged to note a similar milestone, achieved exactly one […]
Men under the age of 40 who use finasteride for alopecia are at risk for suicide if they develop persistent sexual adverse effects and insomnia.
An important pattern of symptoms was common among all cases who committed suicide in the setting of finasteride use – insomnia and persistent sexual dysfunction after medication discontinuation. Insomnia and fatigue/tiredness were some of the most debilitating symptoms… Men under the age of 40 who use finasteride for alopecia are at risk for suicide if they develop persistent sexual adverse effects and insomnia.

Two subjects—eight percent—committed suicide during or after the study.
While the sexual side effects of 5ARIs are well known, there may be persistent genitourinary, physical, psycho-cognitive, anti-androgenic and penile vascular changes after 5ARI discontinuation. Use of 5ARIs for treatment of AGA may lead to persistent sexual, genitourinary, physical, psycho-cognitive, and anti-androgenic sequelae even after cessation of 5ARI therapy… Two subjects (8%) committed suicide during or after the study.

Health care professionals should…conduct a full evaluation and a…risk-benefit assessment for patients before each prescription of finasteride.
As prescribers, our primary duty is to do no harm. Health care professionals should keep themselves abreast of these potential signals and, accordingly, conduct a full evaluation and a detailed, personalized risk-benefit assessment for patients before each prescription of finasteride.

This drug for young men must be taken off the market.
As of 2018, 15,000 cases of adverse reactions to finasteride were reported to the WHO—which is a huge number to begin with. And the interesting thing is that the average age of this group was 32 to 34 years old… This drug for young men must be taken off the market.
