Does Finasteride Cause Erectile Dysfunction? Side Effects and Solutions

Taking hair loss medication can lead to erectile dysfunction?

Hello, I have been taking Finta (Finasteride) at a dosage of 1/4 tablet daily for over a month without any issues.
However, around the two-month mark, I suddenly started experiencing difficulties with maintaining an erection, and I find it hard to achieve an erection now; I mostly only have morning erections left, and my libido has decreased significantly.
Here are my questions:
1.
Is it normal for side effects to appear after such a long time?
2.
I have heard that some people return to normal after continuing the medication; would you recommend that I keep taking it?
3.
Should I go see a doctor directly? Should I first return to the dermatologist to assess the situation, or should I go directly to a urologist?

More Info

Finasteride, commonly known by brand names such as Proscar and Finta, is a medication primarily used to treat male pattern baldness and benign prostatic hyperplasia (BPH). While it is effective for these conditions, it is also associated with a range of side effects, including sexual dysfunction. Your concerns regarding erectile dysfunction (ED) and decreased libido after starting Finasteride are not uncommon and warrant a thorough understanding.

1. Delayed Onset of Side Effects: It is indeed possible for side effects to manifest after a period of normal use. Finasteride works by inhibiting the enzyme 5-alpha-reductase, which converts testosterone into dihydrotestosterone (DHT). This hormonal alteration can lead to sexual side effects, and while some individuals may experience these effects shortly after starting the medication, others may not notice them until weeks or even months later. The variability in response can be attributed to individual differences in metabolism, hormonal balance, and psychological factors.

2. Continuation of Medication: Some studies and anecdotal reports suggest that sexual side effects may improve over time for some individuals who continue taking Finasteride. However, this is not guaranteed, and the decision to continue should be made cautiously. If you are experiencing significant distress or if the side effects are impacting your quality of life, it may be prudent to discuss the possibility of discontinuing the medication with your healthcare provider. It is essential to weigh the benefits of hair loss treatment against the potential for persistent sexual dysfunction.

3. Seeking Medical Advice: Given your symptoms, it is advisable to consult a healthcare professional. You may start with your primary care physician, who can evaluate your symptoms and determine whether a referral to a urologist is necessary. A urologist specializes in male reproductive health and can provide a more focused assessment of your erectile dysfunction. Additionally, if you have concerns about skin reactions or other side effects, consulting a dermatologist may also be beneficial.

In terms of recovery after discontinuation of Finasteride, many individuals report improvements in sexual function within weeks to months after stopping the medication. However, there are cases where side effects may persist longer, leading to a condition known as Post-Finasteride Syndrome (PFS), characterized by prolonged sexual dysfunction even after the drug has been discontinued. If you decide to stop taking Finasteride and do not see improvement in your symptoms within a few months, it is crucial to seek further medical evaluation.

In conclusion, while Finasteride can be effective for treating hair loss, it is essential to be aware of its potential side effects, including erectile dysfunction. If you are experiencing these issues, consider discussing your situation with a healthcare provider who can help you navigate your options and determine the best course of action for your health and well-being. Remember, your sexual health is an important aspect of your overall quality of life, and addressing these concerns is vital.
