Post Finasteride Syndrome: Is it Real? Hair Transplant Surgeon’s Thoughts

The Truth About Post Finasteride Syndrome

Post Finasteride Syndrome Is it Real? Hair Transplant Surgeon’s Thoughts

On September 12, 2019 Reuters released a front page investigative report  on the hair loss drug Propecia and whether Merck Pharmaceuticals had been covering up data to hide some potentially serious side effects from the public. If you are balding, this medication is the best treatment on the market so you might want to read further.

What is finasteride (Propecia)? Propecia Box

Finasteride is a drug that has been around since the 1990’s. In the 5mg form, it is used to treat an enlarged prostate and in the 1mg form (sold as Propecia) it is used to help slow down, stop or even reverse male hair loss. While there are a multitude of non-surgical hair loss options on the market, finasteride is the only drug that, by itself, works the majority of the time.

Though very useful, Propecia has some limitations and side effects. Firstly, it can only be used in men and more significantly large studies have found a 2% incidence of sexual dysfunction and reduction in sperm count and activity in certain males. Large scale studies have found that after cessation of the product, these side effects are reversed and in many, after longterm use they can cease.

What is Post Finasteride Syndrome (PFS)?Post Finasteride Syndrome Male

A small subset of patients claim hormonal, psychological and neurological symptoms that persisted despite stopping taking the medication. A group of practitioners, lawyers and non-dermatologists created a foundations and a large scale lawsuit was filed in 2016 against Merck. (link) Considering that some patients developed severe depression through the course of PFS, that in certain situations even led to suicide, there is a lot at stake in this case.

What did the Reuters investigative report find?

The Reuters report uncovered some court filings from this lawsuit that demonstrated that Merck understated the number of men with sexual side effects and their duration. In addition there are internal Merck documents that manifest that Merck knew 20 years ago that sales would suffer if the public knew about some of this data.

Is it safe to take finasteride?Before and After Propecia

I wholeheartedly believe that post finasteride syndrome exists, but it is not a condition that is caused by finasteride. Rather, it likely occurs as a psychological condition in a predisposed subset of people who have a higher likelihood towards mental health issues. There is also a possibility that a VERY small subset of patients can experience persistent symptoms after stopping the medication and I do counsel my patients on this.

The Verdict:

I took finasteride for years myself. I would never recommend something I was afraid to take. I recently switched to a special topical formulation which has no systemic side effects and  I initial data on this treatment form is promising so I think in the long run I will try to switch most of my patients to that. I rarely trust the honesty of big pharmaceutical corporations but in this case I think the Reuters report misses the mark.

The professional medical community has extensively done independent research  on this topic the International Surgical Hair Restoration Society created a specific task force to look into this and found NO validity. I would stand by their unbiased opinion. Of course if you want to know about alternatives or surgical options, there are many and my Hair Loss Prevention MasterClass goes into this in detail.
