Sustiva is used to treat HIV infection in combination with other anti-HIV medications. If Sustiva is the only drug you take to treat HIV infection, it may stop working. Sustiva 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). Sustiva is also known as Efavirenz, Stocrin. Sustiva 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. Sustiva 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. Sustiva does not kill existing HIV virus and it is not a cure for HIV.
Take this drug by mouth, generally once daily as directed. Take on an empty stomach with a glass of water. Taking Sustiva with food, especially a high-fat meal can lead to increased blood levels of the drug and increase your risk of having side effects.
Best taken at bedtime during the first month of use. Using this drug regularly at bedtime may decrease certain side effects. Use this medication regularly in order to get the most benefit from it.
