Propecia Lowers The Reading On PSA Screening Tests, Even Though Risk Is Still There
(WebMD) The hair-loss drug Propecia lowers the reading on the PSA prostate cancer screening test, U.S. researchers find.
This means men on Propecia may have dangerously high PSA levels even if their test scores are in the normal range, the researchers say.
It's already known that Proscar — a drug for men with enlarged prostates — affects the PSA test.
Propecia is a low-dose version of Proscar — 1 mg of finasteride in Propecia, versus 5 mg in Proscar.
Does the low-dose drug have the same PSA effect as the high-dose drug?
