What are Finasteride side effects in women?

The side effects of finasteride in women have been  delineated by the other Physicians. It has been my experience that oncologists do not approve of using finasteride in women who have had breast cancer. 

Woman do nor use it. Finasteride causes child birth defect and anomalies of baby if used in child bearing age of woman .if you are in menapouse  you may try to use 5 mg finasteride daily.

Thank you for your question. There was a study 5 years ago using finasteride 5 mg daily in women. Previous findings over 15 year ago showed finasteride 1 mg daily to be ineffective in women. The findings were that with the 5 mg dose over 90% of women self reported a huge or moderate response rate for preserving and restoring hair. 8 of the 43 women had decreased libido, 4% had headache or nausea which resolved. This study was limited in size and not a double blinded study which is the gold standard. For the time being, the FDA has only approved finasteride for the treatment of androgenetic alopecia in men. Treatment of women is considered an "off-label use". There is the risk for severe fetal malformations in pregnant women and finasteride should not be given to women of child bearing capacity. In men, the combination of finasteride and minoxidil (Rogaine) is more effective than single therapy.It is best to consult with a hair restoration specialist to get their recommendations for restoring and preserving your hair.I hope this was helpful - Dr. Moore.
