Valganciclovir (valganciclovir) — Uses, Dosage, Side Effects & Safety

Drug class: Infectious & Communicable Diseases

Overview

Valganciclovir is an antiviral medication used to treat and prevent infections caused by cytomegalovirus (CMV), especially in people with weakened immune systems, such as organ transplant recipients and individuals with HIV/AIDS. It is also used to treat CMV retinitis, a serious eye infection that can lead to blindness if left untreated. Valganciclovir works by stopping the growth and spread of CMV in the body. It is a prodrug, meaning it is converted in the body to ganciclovir, which directly inhibits viral DNA replication. Patients should know that valganciclovir does not cure CMV but helps control the infection. It is important to take the medication exactly as prescribed and to have regular blood tests to monitor for side effects.
