Proscar (Finasteride) for Prostatitis

Proscar (PRAH-scar)

Proscar (finasteride [fih NAH steh ride]) is a 5 alpha reductase inhibitor that prevents conversion of testosterone to dihydrotestosterone. It is used in men to shrink an enlarged prostate (benign prostatic hyperplasia—BPH). It helps relax muscles to increase urine flow and reduce pain for men with prostatitis.

Proscar Warnings

Proscar may artificially decrease PSA levels. Be sure to inform any lab technicians and physicians that you are taking this drug if you are being tested for prostate cancer.

Proscar and other 5 alpha reductase inhibitors are linked to a risk of aggressive prostate cancer.

This drug may cause birth defects in male babies, male infertility, and poor quality semen. Discuss the effects of Proscar with your physician before taking this medication for Prostatitis if you have plans to later become a father.

If the coating on the tablet has been penetrated or crushed, this drug should not be handled by a woman who is pregnant or planning to have children, as Proscar can be absorbed in the skin and causes genital birth defects in male infants.
