## What is valganciclovir?

Valganciclovir is used in adults to prevent infection with cytomegalovirus (CMV) that may occur 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.

## Warnings

Do not use if you are pregnant. Valganciclovir can cause birth defects. Tell your doctor right away if a pregnancy occurs while either the mother or the father is using valganciclovir.

Use effective birth control to prevent pregnancy, whether you are a man or a woman. Keep using birth control for at least 30 days after your last dose of valganciclovir if you are a woman, or for at least 90 days after your last dose if you are a man.

Call your doctor right away if you have signs of infection such as: fever, chills, tiredness, flu symptoms, mouth sores, skin sores, pale skin, easy bruising, unusual bleeding, shortness of breath, or feeling light-headed.
