Hair loss can be a frustrating experience, but for many people, medications like finasteride offer hope. However, a small percentage of men who use finasteride may experience a range of persistent symptoms known as Post-Finasteride Syndrome (PFS). PFS is a complex and poorly understood condition that can cause sexual dysfunction, physical and neurological symptoms, and an increased risk of suicide attempts.[1] Despite the severity of these symptoms, PFS remains a relatively unknown condition, and there is no known cure. In this article, we will look at the dangers and signs of PFS. We will also discuss ways to handle and heal from this difficult condition.
What is Finasteride?
Finasteride[2] is a medication that is primarily used to treat
- enlarged prostate glands (benign prostatic hyperplasia)[3]
- male pattern baldness (androgenic alopecia).
It belongs to a class of drugs known as 5-alpha-reductase inhibitors. Finasteride works by blocking the conversion of testosterone into dihydrotestosterone (DHT). DHT is a hormone that contributes to the growth of the prostate gland and hair loss in men.
By reducing DHT levels, finasteride helps to shrink the prostate gland and prevent further hair loss. It is available in tablet form and is usually taken once a day.
Finasteride was approved by the FDA in 1992 for the treatment of BPH and in 1997 for androgenic alopecia. It has since become a popular and widely prescribed medication for these conditions.
Finasteride can help with BPH and baldness in men, but it may have side effects. These side effects include decreased sex drive, erectile dysfunction, and ejaculation disorders. But for most men, these side effects go away when they stop taking the medication. Discuss any concerns or potential risks with a doctor before starting finasteride treatment.
What is Post Finasteride Syndrome (PFS)?
PFS[4] is a term for long-term side effects that some people have after stopping Finasteride. Most users handle the drug well, but a few may have lasting symptoms.
Symptoms of PFS can include sexual dysfunction, depression, anxiety, and muscle wasting. Some men also report experiencing physical symptoms. These include joint pain, fatigue, and gynecomastia (breast enlargement).
The exact cause of PFS is not fully understood. It is believed to be related to the suppression of the hormone DHT by finasteride. DHT is essential in developing and maintaining male sexual characteristics and other physiological processes.
Post-Finasteride Syndrome Symptoms
PFS is a condition that can manifest with a variety of symptoms. The severity and duration of symptoms can vary from person to person. There are some common symptoms associated with PFS. Not all individuals with PFS will experience the same set of symptoms. Some may experience a combination of physical, sexual, and psychological effects. Here are some of the commonly reported symptoms of PFS[5]:
- Sexual Dysfunction:
- Erectile dysfunction (difficulty achieving or maintaining an erection)
- Reduced libido (loss of sexual desire)
- Decreased ejaculate volume
- Difficulty reaching orgasm
- Fatigue and Muscle Weakness:
- Persistent and debilitating lack of energy
- Decreased stamina and physical endurance
- Generalized muscle weakness
- Cognitive Difficulties:
- “Brain fog” characterized by difficulties with memory, concentration, and mental clarity
- Slower cognitive processing
- Impaired cognitive function
- Gastrointestinal Disturbances:
- Abdominal pain or discomfort
- Bloating
- Constipation or diarrhea
- Skin and Hair Changes:
- Dry skin
- Increased skin sensitivity
- Hair texture alterations (thinning, changes in quality)
- Emotional and Psychological Effects:
- Depression
- Anxiety
- Irritability
- Mood swings
- Reduced sense of well-being
- Sleep Disturbances:
- Difficulty falling asleep
- Frequent awakenings during the night
- Poor sleep quality
The reason for PFS is unclear, but it may be connected to how finasteride affects DHT levels. Some experts believe that the symptoms of PFS may be due to epigenetic changes. The symptoms might also be a result of changes in how genes are expressed due to exposure to finasteride.
PFS is a rare but severe condition. It can significantly impact a man’s physical, mental, and sexual health. While no known cure for PFS exists, treatments may help reduce some symptoms. If you have ongoing symptoms after taking finasteride, talk to a doctor. They can check if PFS is the reason.
How Common Is Post-Finasteride Syndrome?
The prevalence of PFS is not well established. There is limited research on this condition and no standardized diagnostic criteria.
A study found that about 2.1-7.7% of men may have ejaculation problems after stopping finasteride.[6] Not all of these men may meet the criteria for PFS. This suggests that a few men who take finasteride might have lasting sexual side effects.
During a one-year trial, men with male pattern baldness taking 1mg of finasteride daily reported some side effects. These included decreased libido, which 1.8 percent of men experienced. Additionally, 1.3 percent reported erectile dysfunction, and 1.2 percent had ejaculation disorders.[7]
PFS is often associated with finasteride. It needs to be clarified why some men develop this condition while others do not.
- Genetics
- Individual differences in hormone levels
- Other medical conditions
may play a role in determining who is at risk for PFS. Before taking finasteride, talk to your doctor about its risks and benefits. Also, be aware of possible side effects like PFS.
Finasteride Withdrawal Symptoms
There is limited research on the withdrawal symptoms associated with finasteride. Some men who stop the medication may experience symptoms for weeks or months. These symptoms are sometimes referred to as “post-withdrawal syndrome”. They may include the following:
Rebound Hair Loss
Finasteride is often used to treat male pattern baldness. Stopping the medication may temporarily increase hair loss.
Sexual Dysfunction
After men stop taking finasteride, they may have temporary worsening of sexual side effects. These include decreased libido or erectile dysfunction.
Mood changes
After stopping finasteride, some men may feel moody or experience anxiety and depression.
Physical symptoms
After stopping finasteride, men may feel tired, weak, or have pain in their muscles and joints.
These symptoms are generally temporary and should improve over time. However, in some cases, men may experience symptoms similar to those seen in PFS. If you are experiencing symptoms after discontinuing finasteride, discuss these with a doctor. They might suggest more tests or send you to a specialist to help with your symptoms.
Finasteride Long-Term Effects
Finasteride is usually safe and works well, but some worry it may have long-term effects. One of the finasteride’s most well-known long-term effects is PFS. Men who stop taking PFS may have sexual, physical, and mental side effects. PFS’s exact prevalence is unknown. Studies suggest that around 15% of men who take finasteride may have sexual side effects.[8]
Besides PFS, using finasteride might raise the risk of certain health conditions. These include:
High-grade prostate cancer
Some studies have suggested that finasteride use may increase the risk of high-grade prostate cancer. However, other studies have not found this association.
Depression and anxiety
Using finasteride may increase the risk of depression and anxiety, but the evidence is mixed.
Cognitive impairment
Studies have shown that using finasteride might increase the risk of cognitive problems. These problems could include memory issues and trouble concentrating.
Congenital disabilities
Finasteride can cause congenital disabilities if pregnant women take it. Using the medication may also raise the chance of birth defects in male children.
The long-term effects of finasteride need to be better understood. We need more research to understand the risks associated with its use. It is important to talk to your doctor about the risks and benefits of finasteride.
How do you protect yourself from PFS when taking Finasteride?
If you’re thinking about using finasteride for prostate issues or hair loss, be careful of PFS. While it is a rare condition, you must be informed and proactive about your health. Here are some steps you can take to protect yourself:
Consult with a healthcare professional:
Before starting any medication, including finasteride, have a thorough discussion with a doctor. They can provide you with information about the risks and benefits of finasteride.
Educate yourself about the potential side effects:
Familiarize yourself with the side effects of finasteride, including those associated with PFS. This knowledge will help you recognize any unusual symptoms.
Follow the prescribed dosage:
Take finasteride as prescribed by your healthcare professional. Avoid taking higher doses. Do not change the frequency of the medication without their guidance.
Monitor your symptoms:
Pay attention to any changes in your physical or mental well-being while taking finasteride. If you notice any concerning symptoms, such as sexual dysfunction or mood changes, inform your doctor.
Consider alternative treatments:
If you have concerns about the risks of finasteride or have a history of sensitivity to medications, discuss alternative treatment options with your doctor. There might be other treatments for your condition that don’t have the risks of finasteride.
How Long Does Post-Finasteride Syndrome Last?
The exact duration of PFS is poorly understood. The condition can vary widely in terms of symptom severity and duration.
Some men have PFS symptoms for a few weeks or months, while others have them for years or indefinitely. In a study, researchers followed up with men diagnosed with PFS. They found that symptoms ranged from 3 months to 20 years, with an average duration of 40 months.[9]
Some men may have PFS symptoms for a long time, but the symptoms can also get better with time. In some cases, treatment options such as
- hormone therapy
- cognitive-behavioral therapy
- antidepressant medication
may help manage PFS symptoms.
Post-Finasteride Syndrome Diagnosis and Treatment
Diagnosing Post Finasteride Syndrome can be challenging due to several factors. Firstly, there are no specific diagnostic criteria or validated biomarkers for PFS. Additionally, the symptoms of PFS can overlap with other conditions. Hence making it necessary to rule out alternative causes. A comprehensive evaluation of symptoms, medical history, and physical examination is typically required to make an accurate diagnosis.
When evaluating PFS, healthcare professionals may consider various medical tests and evaluations. These can include hormone level assessments, such as measuring
- testosterone
- dihydrotestosterone (DHT)
- other relevant hormones.
Laboratory tests may also help rule out other potential causes of symptoms. Additionally, a detailed review of symptoms, medical history, and physical examination can provide important insights.
The treatment of PFS is a topic of ongoing research and debate. There is currently no definitive cure for this condition. Several treatments and therapies have been suggested and tested with varying degrees of success.
Current treatment options for managing PFS symptoms:
Managing PFS symptoms can be challenging, and there is no universally effective treatment. However, several approaches may be considered:
- Symptom-specific treatments: Medications and therapies can target specific symptoms. For example, phosphodiesterase-5 inhibitors may be prescribed to address erectile dysfunction. However, individual responses to treatments may vary.
- Hormonal therapies: Some individuals may benefit from hormonal interventions to rebalance hormone levels. This approach should be undertaken under the guidance of a knowledgeable healthcare professional. It can balance hormones and improve sexual function and desire.
- Psychological support: PFS can have a significant impact on mental health. Talking to a therapist can help you feel better if you’re feeling down or anxious.
Coping with Post Finasteride Syndrome
Strategies for dealing with finasteride withdrawal symptoms include:
1. Healthy lifestyle:
Maintaining a healthy lifestyle can support overall well-being. This includes regular exercise, a balanced diet, and adequate sleep.
2. Symptom management:
Finding strategies to manage specific physical symptoms can be helpful. For instance, you can try relaxation techniques, do gentle exercises, and talk to a doctor about specific symptoms.
Emotional support and coping mechanisms
1. Seek support:
Reach out to support networks, such as friends, family, or online communities dedicated to PFS. Sharing experiences and connecting with others facing similar challenges can provide emotional support.
2. Counseling or therapy:
Consider seeking professional help to address emotional challenges. Therapy can provide a safe space to explore feelings, develop coping mechanisms, and improve overall emotional well-being.
Lifestyle changes and self-care practices:
1. Stress management
Engage in stress reduction techniques. These include meditation, mindfulness, and deep breathing exercises. You can also engage in hobbies and activities that bring joy.

There is no known cure for PFS. Some people do experience spontaneous recovery from their symptoms over time. The duration and extent of recovery can vary widely from person to person. Also, it’s not clear what factors may contribute to this outcome.
Overall, treating PFS is a complex and multifaceted issue. It requires a personalized approach tailored to each individual’s needs and symptoms. If you are experiencing symptoms of PFS, consult with a doctor who knows about this condition. They may help you develop a treatment plan that is safe and appropriate for your situation.
Post Finasteride Syndrome Recovery
Besides medical treatment, specific lifestyle changes may also help promote recovery from PFS. These may include
- maintaining a healthy diet
- exercising
- reducing stress
- avoiding alcohol and drugs.
Recovery from PFS may take time and can vary depending on the severity of your symptoms. Some men see progress over a few months, while others may need longer treatment.
Finasteride Alternatives
While PFS is rare, some people may prefer to explore alternative treatments to avoid potential side effects. Here are some alternatives to consider:
Minoxidil:
Minoxidil is an FDA-approved over-the-counter medication. It is generally used to promote hair growth in both men and women. It is available in topical solution or foam form. Moreover, Minoxidil has shown effectiveness in slowing hair loss and promoting hair regrowth.[10]
Low-Level Laser Therapy (LLLT):
LLLT is a non-invasive treatment. It uses red light to stimulate hair follicles and promote hair growth. This therapy can be delivered through handheld devices or in-office treatments.
Ketoconazole Shampoo:
Ketoconazole is an antifungal agent. Some studies suggest that ketoconazole may have a positive effect on hair growth when used in shampoo form. It is believed to work by reducing inflammation and DHT levels in the scalp.
Saw Palmetto:
Saw palmetto is a natural supplement. It may help block the conversion of testosterone to dihydrotestosterone (DHT). DHT is the hormone responsible for hair loss in genetically susceptible individuals. However, its efficacy for hair loss is not as well-established as finasteride.
Biotin Supplements:
Biotin is often promoted for improving hair health. It may help with hair thickness and strength. While it won’t address the root cause of male pattern baldness, it could complement other treatments.
Lifestyle Changes:
Maintaining a healthy lifestyle can positively impact overall health, including hair health. A healthy lifestyle includes:
- a balanced diet
- regular exercise
- stress management
Hair Transplantation:
For more severe cases of hair loss, hair transplantation surgery may be an option. This involves moving hair follicles from one part of the body to the thinning or balding areas.
Seeking Professional Help and Support
If you suspect that you are experiencing PFS, seeking professional help is essential. Consulting with doctors can provide you with appropriate guidance and support.
A comprehensive medical evaluation is crucial for individuals with suspected PFS. This evaluation may include-
- a detailed review of symptoms
- a physical examination
- laboratory tests
to assess hormonal levels and rule out other potential causes of symptoms.
The diagnostic process aims to ensure an accurate diagnosis and guide the development of an appropriate treatment plan.
Living with PFS can be challenging, but you are not alone. Online communities and support groups dedicated to PFS provide a platform for individuals to connect, share experiences, and exchange information. These communities can offer valuable emotional support and practical advice for coping with PFS.
The Final Thought
Finasteride can lead to a rare condition called PFS, causing lasting side effects. If you experience PFS symptoms after stopping the medication, see a doctor. While there’s no cure, treatments like hormone therapy and therapy can assist. Before using finasteride, discuss its pros and cons with your doctor. If PFS symptoms arise, seek medical guidance and prioritize your health by making informed treatment decisions.
