Enter the original Prostate-Specific Antigen level into the calculator to determine the adjusted PSA after taking Finasteride. This calculator can also evaluate any of the variables given the others are known.

The following formula is used to calculate the Finasteride PSA Adjustment.

Adjusted PSA = PSA / 0.5

Variables:

• Adjusted PSA is the adjusted Prostate-Specific Antigen level after taking Finasteride PSA is the original Prostate-Specific Antigen level before taking Finasteride

To calculate the Finasteride PSA Adjustment, divide the original Prostate-Specific Antigen level by 0.5. This is because Finasteride is known to reduce the PSA levels by approximately 50%. Therefore, to get the adjusted PSA level, the original PSA level is divided by 0.5.

## What is a Finasteride Psa Adjustment?

Finasteride PSA adjustment refers to the recalibration of Prostate-Specific Antigen (PSA) levels in men taking the drug Finasteride. Finasteride, a medication used to treat conditions like benign prostatic hyperplasia and male pattern baldness, can lower PSA levels by approximately 50%. Therefore, to accurately assess a man’s risk of prostate cancer while on this medication, doctors often double the PSA test results. This adjustment helps in providing a more accurate interpretation of PSA levels and potential prostate cancer risk.

## How to Calculate Finasteride Psa Adjustment?

The following steps outline how to calculate the Finasteride PSA Adjustment.

1. First, determine the original Prostate-Specific Antigen level before taking Finasteride (PSA).
2. Next, gather the formula from above = Adjusted PSA = PSA / 0.5.
3. Finally, calculate the Finasteride PSA Adjustment.
4. After inserting the variables and calculating the result, check your answer with the calculator above.
