About Proscar 

Proscar is considered a 5-alpha-reductase inhibitor, which prevents the conversion of testosterone to dihydrotestosterone (DHT).

Proscar is used to treat benign prostatic hyperplasia (BPH) in men with an enlarged prostate. It can also help treat the sudden inability to pass urine related to BPH in men with an enlarged prostate. Proscar is available only by prescription. It is available in a generic formulation as well as under different brand names, including finasteride.

Proscar may be prescribed as a tablet. It’s always important to follow the specific instructions on your prescription, as they can vary based on the formulation and dosage prescribed.

If you're prescribed Proscar, be sure to complete the full course of the 5-alpha-reductase inhibitor unless your doctor specifically tells you to stop. If you don’t complete your prescription, the medication may not fully treat your BPH symptoms.

Proscar uses

There are several FDA-approved uses for Proscar, but it may also be used off-label to treat other conditions. Your online healthcare professional may prescribe it for any of the following common reasons. It’s also possible that your healthcare professional may prescribe it for other reasons not listed here. If you have questions about why a medication is prescribed, ask your online doctor or pharmacist.

  • Benign prostatic hyperplasia (BPH)

    Proscar is FDA-approved to treat an enlarged prostate (benign prostatic hyperplasia) in adult men. It may be prescribed alone or used as a combination therapy with other medications to reduce BPH symptoms.

    Proscar may help treat symptoms of BPH, such as the sudden inability to urinate. Proscar can help improve urine flow, decrease the urge to urinate, and reduce nighttime urination.

    Proscar is not FDA-approved to treat prostate cancer.
