Welcome

The Post-Finasteride Syndrome Foundation’s primary mission is to fund research on the characterization, underlying biologic mechanisms and treatments of post-finasteride syndrome (PFS). Other goals include generating public awareness of PFS and providing support for patients suffering from the condition.

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. Discontinuation of the drug should actually make the hormones work again.…but apparently, something breaks down in some men, in the prostate, in the brain, in the whole organism.

Blocking 5alpha-reductase by finasteride treatment may have broad consequences for the nervous system.

[W]e have evaluated in male rats the effects of a subchronic treatment with low doses of finasteride.…and the consequences of its withdrawal.…on neuroactive steroid levels…. Interestingly, at the withdrawal, some of these effects persisted, and different changes in neuroactive steroid levels, and in the expression of receptors, were also detected. Altogether these findings suggest that the block of the enzyme 5alpha-reductase by finasteride treatment may have broad consequences for the nervous system.

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.

Propecia should not have been authorized in the first place, and its approval should be revoked as soon as possible.

Propecia was approved in 1997 as a solution to slow male pattern baldness. Finasteride is not only poorly effective, but it can lead to infertility. As we stated in 2006, we advise against a cosmetic product with potential endocrine side effects. Propecia should have never been approved, and its authorization should be revoked as soon as possible.
