What is Proscar, and what is it used for?
Proscar is a brand of finasteride, a medicine used to treat symptoms of an enlarged prostate (benign prostatic hyperplasia, BPH). It can also be prescribed as part of strategies to reduce the risk of prostate cancer in certain men, depending on clinician judgment and patient risk factors.
What does finasteride do in the body?
Finasteride lowers levels of the hormone dihydrotestosterone (DHT) by inhibiting the conversion of testosterone to DHT. Because DHT contributes to prostate growth, reducing it can shrink the prostate and improve urinary symptoms associated with BPH.
What are common side effects patients ask about?
Common side effects can include sexual side effects (such as reduced libido or erectile/ejaculatory changes) and breast tenderness or enlargement. As with other prescription medicines, individual risks vary, and patients should discuss side effects with a clinician if they occur or worsen.
How long does Proscar take to work?
Prostate-related symptom improvement typically takes time. Many patients notice changes over weeks, with fuller effects often taking longer than the first month of therapy. Clinicians may reassess symptom response after an initial trial period.
How does Proscar affect PSA testing?
Finasteride can lower prostate-specific antigen (PSA) levels. Because PSA is used to help assess prostate cancer risk, clinicians interpret PSA results differently in patients taking finasteride.
Is there a generic version of Proscar?
Finasteride is available as generics in many countries, meaning the active ingredient is not limited to the Proscar brand.
