Ganciclovir — Uses, Dosage, Side Effects & Safety

Drug class: Antiviral (Nucleoside Analog)

Overview

Ganciclovir 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 or those with HIV/AIDS. It is also used to treat CMV retinitis, an eye infection that can lead to blindness if left untreated. Ganciclovir works by interfering with the replication of viral DNA, which helps to stop the virus from multiplying in the body. This action helps control the infection and reduces the risk of complications. Key points for patients: Ganciclovir can cause serious side effects, including low blood cell counts. It is important to have regular blood tests while using this medication. Always take it exactly as prescribed, and do not stop without consulting your healthcare provider.
