Finasteride is a prescription medication that comes as an oral tablet. It’s available as the  brand-name drugs Proscar and Propecia and also as a generic drug. The condition that finasteride is used to treat as well as your finasteride dosage may depend on the type of drug used.

What is Finasteride?

Finasteride is a prescription medication and is available as the  brand-name drugs Proscar and Propecia and also as a generic drug.

Finasteride Uses

Propecia is used to treat male pattern baldness and hair loss. It is not used or prescribed  for women or children. 

Proscar is prescribed to treat the symptoms of an enlarged prostate, also known as benign  prostate hyperplasia. It can be used as part of a combination therapy with doxazosin to  reduce the progression of symptoms of enlarged prostate.

How Does Finasteride Work?

Finasteride works by lowering the amount of dihydrotestosterone—a hormone in your  body. DHT typically causes your prostate to grow larger. Lowering the amount of DHT can  prevent your prostate from becoming larger which may also lead to decreased hair loss  and increased hair growth. Fortunately (or unfortunately depending on your preference),  hair growth on other parts of the body is not affected.
