Medications for cytomegalovirus (CMV) are used to treat and prevent CMV infections, and manage CMV complications (such as eye infections) in people with AIDS. They work by inhibiting the replication of the virus, helping to control the infection. Common classes include antiviral agents and DNA polymerase inhibitors. They're available in both oral and injectable forms. Antiviral agents include valganciclovir (Valcyte) and ganciclovir. DNA polymerase inhibitors include cidofovir and foscarnet (Foscavir). Other options like Prevymis (letermovir) and Livtencity (maribavir) are available in oral forms, providing different ways to manage CMV effectively.
