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.

## Finasteride Psa Adjustment Formula

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.

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