Description
USES: This medication is used to control cytomegalovirus (CMV) eye infections (CMV retinitis) in persons with AIDS. This medication is an antiviral that works by stopping the growth of viruses. Controlling CMV retinitis can help decrease the risk of blindness from the infection. Foscarnet is sometimes combined with another antiviral drug, ganciclovir, when the CMV infection does not respond to either drug used alone for treatment. This medication is also used to treat herpes infections (HSV) that do not respond to treatment with acyclovir (acyclovir-resistant). This medication is not a cure for CMV or HSV diseases.
