What is valganciclovir?

Valganciclovir is an antiviral drug. It works by preventing viral cells from multiplying in your body. Valganciclovir will not cure CMV but it can help control the infection.

Valganciclovir treats cytomegalovirus (CMV) infection of the eye in patients with acquired immunodeficiency syndrome (AIDS). Valganciclovir also prevents CMV infection in patients who have received an organ transplant (kidney, heart, or kidney-pancreas).

Valganciclovir may also be used for purposes other than those listed in this medication guide.

Your doctor may have switched you from ganciclovir (Cytovene) to valganciclovir (Valcyte). Be aware that the strength of these two medications is different. A valganciclovir tablet contains more medicine than a ganciclovir capsule. You may not need to use as many valganciclovir tablets as you did ganciclovir capsules. To avoid overdosage, take only as many valganciclovir tablets as your doctor has prescribed. An overdose of this medication can cause serious illness.
