.Efavirenz is an oral medication that is used for the treatment of infections with the human immunodeficiency virus (HIV). It is similar to nevirapine (Viramune) and delavirdine (Rescriptor). Efavirenz is in a class of drugs called reverse transcriptase inhibitors which also includes zalcitabine (Hivid), zidovudine (Retrovir), didanosine (Videx), and lamivudine (Epivir). During infection with HIV, the HIV virus multiplies within the body's cells. The newly-formed viruses then are released from the cells and spread throughout the body where they infect other cells. In this manner, the infection continually spreads to new, uninfected cells that the body is continually producing, and HIV infection is perpetuated. When producing new viruses, the HIV virus must manufacture new DNA for each virus. Reverse transcriptase is the enzyme that the virus uses to form this new DNA. Efavirenz directly inhibits the activity of reverse transcriptase and blocks the production of DNA and new viruses. Unlike zidovudine, efavirenz does not need to be converted to an active form. Efavirenz does not kill existing HIV virus and it is not a cure for HIV. Efavirenz is used for the treatment of HIV infection. . . . . Efavir is one of the growing number of drugs used to fight HIV infection. HIV, the human immunodeficiency virus, weakens the immune system until it can no longer fight off infections, leading to the fatal disease known as AIDS (acquired immune deficiency syndrome). Like other drugs for HIV, Efavir works by impairing the virus's ability to multiply. However, when taken alone it may prompt the virus to become resistant. Efavir is therefore always taken with at least one other HIV medication, such as Retrovir or Crixivan. Even when used properly, it may remain effective for only a limited time.

If Efavirenz is taken alone to treat HIV, it may stop working.Efavirenz (eh-FAH-vih-rehnz) is used with other medicines in the treatment of the infection caused by the human immunodeficiency virus (HIV). HIV is the virus that causes acquired immune deficiency syndrome (AIDS).Efavirenz will not cure or prevent HIV infection or AIDS; however, it helps keep HIV from reproducing and appears to slow down the destruction of the immune system.

People who receive this medicine may continue to have some of the problems usually related to AIDS or HIV disease.Efavirenz is a non-nucleoside reverse transcriptase inhibitor (NNRTI).
