The following people should not take Finasteride for hair loss:
- Women: Finasteride is category X for a reason. It can lead to birth defects. Finasteride cannot be used in pregnant, possibly pregnant, or nursing women and should not be used in women at all. If a woman who is pregnant, is breastfeeding, or could possibly be pregnant, touches a tablet, she must wash her hands immediately with soap and water and contact her physician.
- Children: Finasteride cannot be used in children.
Liver impairment: Since Finasteride is metabolized in the liver, men with liver impairment may not be able to clear Finasteride from the body as easily as men with normal livers.
