What is a Generic Drug?

A generic drug is a copy of the brand-name drug with the same dosage, safety, strength, quality, consumption method, performance, and intended use. Before generics become available on the market, the generic company must prove it has the same active ingredients as the brand-name drug and works in the same way and in the same amount of time in the body.

The only differences between generics and their brand-name counterparts is that generics are less expensive and may look slightly different (eg. different shape or color), as trademarks laws prevent a generic from looking exactly like the brand-name drug.

Generics are less expensive because generic manufacturers don't have to invest large sums of money to develop a drug. When the brand-name patent expires, generic companies can manufacture a copy of the brand-name and sell it at a substantial discount.


Neupogen is a prescription medication to prevent febrile neutropenia and is prescribed for people who are having chemotherapy treatments and need to increase their low white blood cell count. Filgrastim is a G-CSF class drug that stimulates bone marrow so that white blood cells are produced in greater numbers and mature faster into neutrophils ready to fight bacteria in the bloodstream and limit the chances of a neutropenia infection.
