|Viramune is prescribed for
advanced cases of HIV. HIV---the human immunodeficiency
virus that causes AIDS---undermines the immune system
over a period of years, eventually leaving the body
defenseless against infection. Viramune is generally
prescribed only after the immune system has declined and
infections have begun to appear. It is always taken with
at least one other HIV medication such as Retrovir or
Videx. If taken alone, it can cause the virus to become
resistant. Even if used properly, it may be effective for
only a limited time.
Like other drugs for HIV, Viramune works by impairing the virus's ability to multiply.
