Do you have any information on whether Propecia can be taken by women? If yes, what are the results?

F.R.

Propecia (finasteride), a treatment for hair loss commonly used by men, has been studied in women -- but not to treat thinning hair as much as to treat excessive, unwanted hair growth. Hirsutism is the medical term for excessive hair growth in cosmetically undesirable locations. Propecia, by inhibiting conversion of testosterone to its active metabolite in the hair follicles, blocks the growth of unwanted hair. In the cases of "androgenic alopecia," or male-pattern balding, Propecia prevents testosterone from sending these hairs into a shedding and resting phase, but rather allows the hair to grow. For now, the only medication FDA-approved for use against androgenic alopecia in women is topical minoxidil (Rogaine).

Propecia has side effects and should NEVER be taken (or even touched by) a pregnant woman, as it may adversely affect a male fetus. Also, you should NEVER use a medication not specifically prescribed for you (in other words, don't borrow your husband's Propecia!). If you think you may benefit from Propecia, see your doctor.
