• Generic Name: letermovir
• Dosage Forms: tablet, film coated
• Other Brand Names: Prevymis

Prevymis (letermovir) is an antiviral medicine used to help prevent cytomegalovirus (CMV) infection after a stem cell (bone marrow) transplant from a donor.

Prevymis 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.

A CMV-seropositive person is at risk for "reactivation" of the virus if the immune system becomes weak. While normally treatable, CMV infection can be serious in people undergoing a stem cell transplant.

Prevymis comes as a tablet or can be given by your doctor through an IV line (intravenously).
