A member asked:

Please suggest, how much dose of propecia (finasteride) needs to be consumed per day for how many months for male pattern baldness and what are the side effects?

A doctor has provided 1 answer

1 mg: Propecia (finasteride) is prescribed as a dose of 1 mg daily and may take months to see results. Since it interferes with testosterone effects, it can cause erectile dysfunction or decrease in libido. It also may cause hair loss in other parts of the body and can affect the psa test men take to be screened for prostate cancer. In my patients who took it for years, it has been well tolerated and did help.
