Can Propecia be used by women?

Propecia is not suitable for women and must not be taken during pregnancy. The active ingredient finasteride inhibits the conversion of the male sex hormone testosterone into dihydrotestosterone. This can lead to malformations of the external genitals of male unborn children when pregnant women take Propecia.

Crushed or broken film-coated tablets must not be touched by pregnant women. The risk of possible resorption (uptake by the skin) of finasteride may adversely affect the development of the male fetus. Normally, Propecia tablets are coated with a film and prevent contact with the drug under normal handling.
