Is it reasonable to wean Finaster before the PSA test?

Perhaps the doctor wants the most accurate result, and your health condition justifies the possibility of discontinuation of the drug. As for the discontinuation of finasteride, its therapeutic effect persists for several months. In patients with benign prostatic hyperplasia, Finaster causes a decrease in serum PSA levels of about 50% (however, this is somehow approximate), even if the patient suffers from prostate cancer, which should be taken into account when analyzing the result. One study confirmed that in patients treated with finasteride for 6 months or more, PSA values should be doubled by comparing them with values measured in patients who are not treated. Before starting treatment with Finaster, as well as periodically during treatment, a rectal examination of the prostate gland is recommended, as well as other tests to detect prostate cancer, such as plasma PSA measurements. A high level of PSA is a signal that the diagnosis should be deepened and, for example, a biopsy should be considered.
