Propecia and finasteride are taken orally, 5 mg/time, once/day. 5mg/day, can be taken in the morning and evening, before or after meals, long-term use is recommended. Patients with Renal Impairment: No dose adjustment is required in patients with various degrees of renal impairment (creatinine clearance as low as 9 mL/min). Today let’s take a closer look at what kind of medicine Propecia is?

Finasteride is a 4-azasteroid compound. It is a specific inhibitor of type II 5a-reductase, an intracellular enzyme that metabolizes testosterone into dihydrotestosterone. It can very effectively reduce dihydrotestosterone in the blood and prostate. That is, by inhibiting the conversion of testosterone into dihydrotestosterone (DHT), it reduces the size of the prostate and improves symptoms, increases urine flow rate, and prevents benign prostatic hyperplasia (BPH).

Propecia finasteride side effects include: decreased libido, impotence, reduced ejaculation, breast tenderness or enlargement, allergic reactions (including rash, itching, hives, and lip swelling), and testicular pain.

One study shows that using Propecia and Finasteride can prevent men from developing prostate cancer for up to 16 years. The researchers found that 3,244 PCPT participants were diagnosed with prostate cancer an average of 16 years later than the control group. They also found that PCPT participants who took finasteride had a 21% lower risk of death from prostate cancer over 16 years.

Researchers say Propecia finasteride may delay the onset of prostate cancer in patients by seven years longer than previously thought. The drug can protect men from prostate cancer for up to 16 years after they stop using it.

Propecia Finasteride is indicated for the treatment and control of benign prostatic hyperplasia (BPH) and the prevention of urinary events: reducing the risk of acute urinary retention; reducing the risk of transurethral resection of the prostate (TURP) and prostatectomy. Finasteride can shrink the size of an enlarged prostate, improve urine flow, and improve symptoms related to prostatic hyperplasia. Patients with prostatic hyperplasia are suitable for treatment with Propecia and Finasteride.
