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


    Dicloxacillin is a prescription antibiotic that your doctor can prescribe for certain types of infections including skin infections and infections of prosthetic joints. It is typically started in the hospital as an infusion before someone is converted to the oral formulation.

    Dicloxacillin is an antibiotic that works by disrupting the formation of bacterial cell walls. Cell walls protect bacteria from the environment, and by blocking the formation of cell walls, the bacteria die, helping to treat the infection.
