President Trump uses Finasteride for baldness
It is a prescription medication and Merck markets finasteride. In addition for its use for male-pattern hair loss it is also a common prescription medication for enlarged prostrate. Merck sells it under the brand name of Propesia 1 mg tablets. Its big brother is sold as Proscar (5 mg), used for symptoms of enlarged prostrate, or benign prostatic hyperplasia which have been prescribed to over 1 million people. Together, finasteride and a closely related compound, dutasteride (sold as the brand name Avodart) work by blocking the conversion of testosterone to its more potent form, dihydrotestosterone.
The constellation of potential symptoms, sometimes referred to as post-finasteride syndrome, may include sexual, physical and psychological changes. Medical warning are: libido disorders, ejaculation disorders and and orgasm disorders which could be irreversible.
There are approximately 1,370 lawsuits against Merck and a class-action suit as well.
In 1997 FDA approved Propesia. Many younger generation (ages 18 to 41) use this drug.
Further tests and studies are going on to go from here.
