Finasteride is a competitive and specific inhibitor of Type II 5á-reductase, an intracellular enzyme that converts the androgen testosterone into DHT. (Dihydrotestosterone 5á-Dihydrotestosterone is an androgen or male sex hormone.) Finasteride has not been approved for use in women or children. Finasteride is produced by pharmaceutical giant Merck.
Propecia is the 1mg dose of Finasteride. Propecia is used to treat androgenetic alopecia, also known as male pattern baldness.
Proscar is the 5mg dose of Finasteride. Proscar is used to treat Benign Prostatic Hyperplasia (BHP or enlarged prostate).
In December of 2009, MHRA (Medicines and Healthcare Products Regulatory Agency (UK)), released its Assessment Report titled The Risk of Male Breast Cancer with Finasteride. Their findings were as follows:
50 cases of male breast cancer were reported worldwide with the use of 5mg Finasteride (Proscar).
3 Cases of male breast cancer reported worldwide with the use of 1mg Finasteride (Propecia).
Most cases were reported within five years of starting treatment.
An information update released by Health Canada on August 4, 2011 indicates individuals taking Finasteride (Propecia or Proscar) should report any changes in their breasts to their doctor. Changes may include breast enlargement, lumps, tenderness, pain or nipple discharge.
Suspected side effects may be reported to the Food and Drug Administration (FDA) by going to www.fda.gov and completing the MedWatch Online Voluntary Reporting Form (3500).
While the chances of a male getting breast cancer are low, the chances double if taking Finasteride!
