Finasteride is a medication primarily used to treat two common conditions in men: benign prostatic hyperplasia (BPH) and male pattern baldness (androgenetic alopecia).
In the case of BPH, which is an enlargement of the prostate gland that can cause urinary problems, finasteride helps by reducing the size of the prostate. It does this by inhibiting the conversion of testosterone, a male hormone, into dihydrotestosterone (DHT), which is a more potent form of testosterone that contributes to prostate growth. By lowering DHT levels, finasteride can alleviate symptoms such as difficulty urinating, frequent urination, and urinary urgency.
For male pattern baldness, finasteride is used to slow down hair loss and promote hair regrowth in men. This condition is typically caused by a genetic predisposition and hormonal factors, including the influence of DHT. By blocking the conversion of testosterone to DHT, finasteride can help to maintain existing hair and stimulate the growth of new hair in some individuals.
Finasteride is usually taken orally in the form of a tablet. The recommended dosage and duration of treatment may vary depending on the specific condition being treated, and it is important to follow the instructions provided by a healthcare professional.
While finasteride has proven effective for many people, it's important to note that it may have potential side effects. These can include decreased libido, erectile dysfunction, breast tenderness or enlargement, and changes in mood. If you experience any adverse effects or have concerns, it is advisable to consult with a healthcare professional.
