Generic finasteride is a term used to refer to branded finasteride tablets that are manufactured by other companies rather than MSD. The latter received the patent on both 1mg and 5mg finasteride tablets branded under Propecia and Proscar respectively. However, this patent has expired and therefore other companies have the freedom to produce a reference drug which must be comparable in quality and performance characteristics. Generic finasteride 1mg is a reference drug for Propecia.
NOTE: Please be aware that most generic finasteride 1mg tablets offered on the internet are not produced by a legal, well-established pharmaceutical company but rather underground! Make sure you they clearly state the manufacturer where those specific finasteride tablets can be traced back to. Don’t mess with your health.
