What is the standard dosage for Proscar (finasteride) when treating BPH?

The standard dosage for Proscar (finasteride) when treating benign prostatic hyperplasia (BPH) is 5 mg taken orally once daily. Finasteride works by inhibiting the conversion of testosterone to dihydrotestosterone (DHT), which helps reduce the size of the enlarged prostate and alleviate urinary symptoms associated with BPH. The 5 mg dosage is specifically indicated for this condition and has been established through clinical trials as effective for managing BPH symptoms, making it the appropriate recommendation for patients.

Other dosages listed are not used for the treatment of BPH or are not standard practice for this indication. For example, 1 mg is typically prescribed for male pattern hair loss, while higher doses like 10 mg have not been shown to provide additional benefits for BPH and could increase the risk of side effects without contributing to therapeutic effectiveness. Similarly, 2 mg is not a common dose for this indication. Thus, the 5 mg daily dose is the established standard for treating BPH with Proscar.
