HOW DO AIDS DRUGS WORK?
The HIV virus can make millions of copies of itself every day. Antiretroviral drugs (ARVs) can’t kill the virus, but they can almost stop it from multiplying. A “viral load” test measures the amount of virus in your blood. If you take ARVs, the amount of virus in your blood should go down. If your viral load is very low, you probably won’t develop any AIDS-related illnesses. See Fact Sheet 125 for more information on viral load.
