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.

ISENTRESS (Raltegravir) can be prescribed as part of a combination of drugs to treat Human Immunodeficiency Virus (HIV) infection.
HIV is a virus that causes Acquired Immunodeficiency Syndrome (AIDS). It is a long-term infection that is eventually fatal if left untreated. Successful treatment of HIV infection can delay the development of AIDS, and can sometimes cause long-term remission.
ISENTRESS works by blocking a critical protein involved in HIV replication called HIV-1 integrase. ISENTRESS exhibits antiviral activity by blocking HIV-1 integrase, which prevents the virus from replicating.
Take ISENTRESS exactly as prescribed by the doctor.
For patients who have never taken ISENTRESS, the dose is 400 mg by mouth twice daily OR 1200 mg by mouth once daily.
Patients who have used ISENTRESS in the past should take 400 mg by mouth twice daily.
