Propecia (1mg finasteride) is arguably the most effective medical hair loss treatment currently available. Though not a hair loss cure, countless men have used the drug to effectively slow the progression of balding and regrow hair since its approval for the treatment of androgenic alopecia (male pattern baldness) by the FDA in 1997.
Propecia works by inhibiting the conversion of testosterone to Dihydrotestosterone (DHT). Studies conducted by pharmaceutical manufacturer Merck & Co showed that almost 80% of men using Propecia stopped or even reversed their hair loss to some degree, while fewer than 2% exhibited “Drug-Related Adverse Experiences” or side effects. These side effects were said to be temporary and to subside upon discontinuation of the drug.
However, in the years since Propecia first entered the market as a hair loss treatment, numerous complaints have arisen from men who claim to have suffered severe and irreversible sexual side effects attributed to finasteride use. This has come to be known as “Post Finasteride Syndrome” or “PFS”.
As a result of these complaints, in April of 2012, the FDA mandated labeling changes to finasteride related products. Labeling changes to Propecia include “libido disorders, ejaculation disorders, and orgasm disorders that continued after discontinuation of the drug”. Labeling changes to Proscar include “decreased libido that continued after discontinuation of the drug”. Labeling changes to both Propecia and Proscar include “reports of male infertility and/or poor semen quality that normalized or improved after drug discontinuation”
