Uses

Valganciclovir is an anti-viral drug. It is changed in the body to the active form of the drug called ganciclovir. It is used to prevent disease caused by a virus called cytomegalovirus (CMV) in people who have received organ transplants. CMV disease can lead to serious infections in the body, including an infection in the eye, called CMV retinitis, that can cause blindness. Valganciclovir works by slowing the growth of the CMV virus. It helps prevent the spread of infection to other areas of the body.

Valganciclovir is also used to treat CMV retinitis in people with advanced HIV disease (AIDS). This medication helps control CMV retinitis and decrease the risk of blindness.

Valganciclovir is not a cure for CMV disease. Some people may have worsening CMV retinitis even with treatment. It is important to have your eyes checked regularly by your doctor.
