Spironolactone and finasteride are not recommended for women planning pregnancy due to birthdefect risks. Both need to be stopped months before conception, and finasteride is generally not advised for women.
People on finasteride or dutasteride cannot donate blood due to the risk of birthdefects if the blood is given to a pregnant woman. It's advised to stop finasteride for a month and dutasteride for six months before donating.
Stopping finasteride and minoxidil can cause significant hair shedding, so they should be continued indefinitely. Concerns about finasteride affecting fertility or causing birthdefects are mostly unfounded, but some stop for personal reasons.
A woman experienced hair regrowth after using self-prescribed finasteride and dutasteride from online sources, despite doctors' reluctance to prescribe these due to potential birthdefects. Her dermatologist acknowledged the effectiveness of these treatments and advised her to continue using them while avoiding pregnancy.
A 29-year-old woman with genetic hair loss started using 0.5 dutasteride a week ago and has noticed increased shedding, no sexual side effects, and less oily skin. She plans to provide updates and is not concerned about potential birthdefects as she doesn't plan to have more children.
