Propecia is used for treating certain types of male pattern hair loss (androgenic alopecia) in men. Propecia is a steroid reductase inhibitor. It works by reducing the amount of the hormone dihydrotestosterone (DHT) in the body. This may block certain types of hair loss in men.

- Taking Propecia at the same time each day will help your remember to take it.

Propecia can affect a blood test called PSA (Prostate-Specific Antigen) for the screening of prostate cancer. If you have a PSA test done, you should tell your doctor(s) that you are taking Propecia. Because Propecia decreases PSA levels, changes in PSA levels will need to be carefully evaluated by your doctor(s). Any increase in follow-up PSA levels from their lowest point should be carefully evaluated even if the test results are still within the normal range for men not taking Propecia. You should also tell your doctor if you have not been taking Propecia as prescribed because this may affect the PSA test results. For more information, talk to your doctor.
