These are closely related antiviral medications used to prevent or treat cytomegalovirus (CMV) infection. Valcyte is a newer version of Cytovene that can be given less frequently.
Viral blood tests will have been done on both your child and his or her donor before the transplant to determine if either have previously had this virus. Since CMV can become reactivated when the immune system is weakened, if either your child or his or her donor has had it prior to transplant, take one of these medications for the first few months after transplant, when the risk is greatest. Valcyte may also be needed for several months following any treatment for rejection.
