Further information:5-alpha reductase inhibitors can cause a decrease in mean PSA levels by approximately 50% after 6 months of treatment initiation. Men being treated with dutasteride or finasteride should have a new PSA baseline established after 6 months of treatment (reference: https://cks.nice.org.uk/topics/luts-in-men/prescribing-information/5-alpha-reductase-inhibitors/)
