Table of contents:

Proscar is a prescription drug used to treat benign prostatic hyperplasia (BPH) in men with an enlarged prostate. It contains active ingredient called finasteride, which is used to treat symptomatic benign prostatic hyperplasia (BPH) in men with an enlarged prostate. It works by inhibiting the enzyme that converts testosterone into dihydrotestosterone (DHT), a hormone that can contribute to the development of BPH. By reducing DHT levels, Finasteride can help shrink the prostate gland and improve urinary symptoms.

Proscar can lower prostate-specific antigen (PSA) blood levels, which is a screening tool for detecting prostate cancer risk in me. Finasteride can be used alone or taken in combination with other medications to reduce symptoms of BPH and may also reduce the need for surgery.

Uses and Dosage

Proscar is typically administered in tablet form and taken by mouth, either with or without food, as directed by a medical professional. It should be taken regularly at the same time each day to maximize its effectiveness and continue using it as prescribed. Stopping treatment with Proscar should only be done under the guidance of a doctor. It can take between 6 to 12 months to see any beneficial effects from treatment with Proscar.

The dosage is the same for the treatment of benign prostatic hyperplasia (BPH) and male pattern hair loss. It can be administered alone or in combination with an alpha-blocker, such as doxazosin. It is recommended to assess response after 12 weeks to 6 months of treatment.
