If you stop taking Propecia, you will likely lose the hair you have gained within 12 months of stopping treatment. Propecia is for use by men only and should not be used by women or children.

What is the most important information I should know about Propecia?
Propecia can interact with other medications. Tell your doctor all prescription and over-the-counter medications and supplements you take. Propecia is not for use by women, children, or men with a history of prostate cancer. Finasteride can be absorbed through the skin, and women or children should not be permitted to handle Propecia tablets.
Some men experience sexual side effects including erectile dysfunction and decreased libido. These side effects go away in men who stop taking Propecia. These side effects do not appear to occur in women taking Propecia.
Propecia tablets should not be crushed or split. Doing so could result in too much medication being absorbed by the body.
