What is valganciclovir?

Valganciclovir is used in adults to prevent infection with cytomegalovirus (CMV) that may happen after an organ transplant (heart, kidney, or pancreas). Valganciclovir is also used to treat CMV infection of the eye in adults with acquired immunodeficiency syndrome (AIDS).

Valganciclovir is used in children who are 4 months old to 16 years old to prevent CMV infection after a kidney transplant. Valganciclovir is also used in children who are 1 month old to 16 years old to prevent CMV disease after a heart transplant.

Valganciclovir will not cure CMV but it can help control the infection.

Valganciclovir may also be used for purposes not listed in this medication guide.
