Dizziness: A Symptom of Post-finasteride Syndrome

In this article we review what dizziness is, how it presents in PFS, and the resources and support available for patients experiencing this symptom. 

What does persistent dizziness or persistent bouts of dizziness from finasteride entail?

Dizziness is a feeling of disorientation or an altered sense of balance.

It should be noted that self-reports indicate that it can take up to 3 months for on-drug side effects to resolve after discontinuation of finasteride. After that, the symptoms can be considered persistent. 

How PFS patients describe the effects of dizziness

Here are some descriptions from patients based on documented interviews and stories: 

“I’m feeling really dizzy today, even if I turn my head slightly to the right or left I feel this dizziness in my head.“

“I would get dizzy on finasteride and for a while after stopping.“

How common is dizziness as a symptom of Post-finasteride Syndrome?

While there are estimations of incidence for dizziness as a side effect of finasteride, there is limited data with which to estimate the prevalence of dizziness in PFS. 

Research findings on dizziness in PFS 

Two separate studies have found an overexpressed androgen receptor in affected tissue from PFS patients (Di Loreto et al. 2014; Howell et al. 2021), and in addition one of them examined for and found concurrent differential expression of several thousand genes (Howell et al. 2021). 

It is essential to note that more research into post-finasteride syndrome is desperately needed. PFS is currently without an accurate animal model, pathomechanistic understanding, and as a result, safe and effective treatment. 

Do persistent feelings of dizziness after finasteride go away? Is it reversible?

Some patients have reported improvements in dizziness over time. However, PFS is understood to persist indefinitely, and it is currently without safe and effective treatment. 

Managing and coping with dizziness

For those who may be struggling with symptoms, here are some general recommendations:

  1. Focus on self-care: Try to find routines and activities that help you personally.

  2. Be practical about your life situation and/or relationships: Try not to think too far ahead and catastrophize. PFS affects individuals to different degrees and some experience improvements over time. 

  3. Familiarize yourself with the scientific literature: Read through previous research into PFS on our website in order to better understand your condition.

  4. Support research: Further research into PFS, based on a theory and/or conceptualization of the condition that is backed by all previous research findings and can plausibly explain all symptoms reported by patients, is the only way toward a treatment.

What about supplements or other drugs to help treat symptoms?

There are currently no evidence-based items recommended for treatment of dizziness stemming from PFS. In general, patients have reported worsening by attempting to treat their symptoms with anti-androgenic substances. We are obligated to make patients aware as this has preceded patient suicide.
