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.

  • Product Details


    Norvir is an antiviral medication used to treat human immunodeficiency virus (HIV-1). Since Norvir has been used for several years, it is no longer effective on its own to treat HIV-1 infection. However, it is still used to “boost” the amount of other antivirals and increase their effectiveness.


    The standard dosage of Norvir is 600 mg by mouth twice daily. The dosage may need to be reduced if you are taking other antiviral medications.


    The active ingredient in Norvir is ritonavir, which is the name for Norvir generic.
