What does the term "generic" mean? Do generic medications produce the same effect that the brand name medicines do?

A generic drug is a copy of the brand-name drug with the same dosage, safety, strength, quality, how it is taken, 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 and works the same way in the body in the same amount of time.
