Finasteride

Finasteride is a medication commonly used to manage conditions related to hormone levels in the body. It is often prescribed for issues affecting the prostate gland and hair growth.

This medication works by altering hormone activity, which can help alleviate symptoms associated with these conditions.

Information about Finasteride

Finasteride Uses

Finasteride is typically used in the following situations:

To treat benign prostatic hyperplasia (BPH), which is an enlarged prostate gland.
To manage symptoms of urinary retention associated with BPH.
To promote hair growth in male pattern baldness.
To reduce the risk of needing surgery for BPH.

How Finasteride Works

Finasteride works by inhibiting the enzyme 5-alpha reductase. This enzyme is responsible for converting testosterone into dihydrotestosterone (DHT), a hormone linked to prostate growth and hair loss.

By reducing DHT levels, Finasteride helps to shrink the prostate and promote hair growth in affected individuals.

This action can alleviate symptoms such as difficulty urinating and hair thinning.

Not everyone will experience side effects from Finasteride, and many are mild and temporary. Common side effects may include:

Decreased libido
Erectile dysfunction
Decreased volume of ejaculate
Breast tenderness or enlargement
Rash
Dizziness
Weakness

If you experience serious or persistent symptoms, contact your healthcare provider.
