What is Letermovir?

Letermovir is an antiviral medicine used to help prevent cytomegalovirus (CMV) infection after a stem cell (bone marrow) transplant from a donor. Letermovir is for use in adults who are seropositive for CMV. Seropositive means that the virus is in your blood even if you do not show any symptoms of infection.
