Before you begin using a medication, be sure to inform your doctor of any medical conditions or Allergies you may have, any medications you are taking, whether you are pregnant or breast-feeding, and any other significant facts about your health. These factors may affect how you should use Propecia (Finasteride).

Breast Cancer: Male breast cancer has been reported in a small number of people taking Propecia (Finasteride). It is not known with certainty whether Propecia (Finasteride) can cause breast cancer, but this possibility cannot be ruled out at this time. If you notice any changes in your breasts, such as breast enlargement, pain, tenderness, lumps, or nipple discharge, contact your doctor as soon as possible.

Prostate Cancer: Propecia (Finasteride) may be linked with an increased risk of developing a rare type of cancer called high-grade prostate cancer. The risk of this cancer while taking Propecia (Finasteride) is still considered very small. Note that Propecia (Finasteride) (for male pattern baldness) is not approved to treat prostate cancer. If you have any concerns about your medication, talk to your health care provider.

Liver function: Propecia (Finasteride) is broken down by the liver. Propecia (Finasteride) should be used with caution by people with impaired liver function. If you have liver disease or reduced liver function, discuss with your doctor how Propecia (Finasteride) may affect your medical condition, how your medical condition may affect the dosing and effectiveness of Propecia (Finasteride), and whether any special monitoring is needed.

Pregnancy and birth defects: When absorbed into the system of a pregnant woman, Propecia (Finasteride) may cause abnormalities of the genitals in a male baby. Crushed or broken Propecia (Finasteride) tablets should not be handled by women who are or may become pregnant because Propecia (Finasteride) may be absorbed into the system through the skin.

Children: Propecia (Finasteride) should not be used by children.

Seniors: The use of Propecia (Finasteride) has not been studied in men over the age of 65 years with male pattern hair loss.
