Valganciclovir tablet is a deoxynucleoside analogue cytomegalovirus (CMV) DNA polymerase inhibitor indicated for: Adult Patients (1.1) Treatment of CMV retinitis in patients with acquired immunodeficiency syndrome (AIDS). Prevention of CMV disease in kidney, heart, and kidney-pancreas transplant patients at high risk. Pediatric Patients (1.2) Prevention of CMV disease in kidney and heart transplant patients at high risk. 1.1 Adult Patients Treatment of Cytomegalovirus (CMV) Retinitis: Valganciclovir tablets are indicated for the treatment of CMV retinitis in patients with acquired immunodeficiency syndrome (AIDS) [see Clinical Studies (14.1) ]. Prevention of CMV Disease: Valganciclovir tablets are indicated for the prevention of CMV disease in kidney, heart, and kidney-pancreas transplant patients at high risk (Donor CMV seropositive/Recipient CMV seronegative [D+/R-]) [see Clinical Studies (14.1) ]. 1.2 Pediatric Patients Prevention of CMV Disease : Valganciclovir tablets are indicated for the prevention of CMV disease in kidney transplant patients (4 months to 16 years of age) and heart transplant patients (1 month to 16 years of age) at high risk [see Clinical Studies (14.2) ].

Valganciclovir is contraindicated in patients who have had a demonstrated clinically significant hypersensitivity reaction (e.g., anaphylaxis) to valganciclovir, ganciclovir, or any component of the formulation [see Adverse Reactions (6.1) ]. Hypersensitivity to valganciclovir or ganciclovir (4)

Acute renal failure: Acute renal failure may occur in elderly patients (with or without reduced renal function), patients who receive concomitant nephrotoxic drugs, or inadequately hydrated patients. Use with caution in elderly patients or those taking nephrotoxic drugs, reduce dosage in patients with renal impairment, and monitor renal function (2.5 , 5.2 , 8.5 , 8.6) . 5.1 Hematologic Toxicity Severe leukopenia, neutropenia, anemia, thrombocytopenia, pancytopenia, and bone marrow failure including aplastic anemia have been reported in patients treated with valganciclovir or ganciclovir. Valganciclovir should be avoided if the absolute neutrophil count is less than 500 cells/μL, the platelet count is less than 25,000/μL, or the hemoglobin is less than 8 g/dL. Valganciclovir should also be used with caution in patients with pre-existing cytopenias and in patients receiving myelosuppressive drugs or irradiation. Cytopenia may occur at any time during treatment and may worsen with continued dosing. Cell counts usually begin to recover within 3 to 7 days after discontinuing drug. In patients with severe leukopenia, neutropenia, anemia and/or thrombocytopenia, treatment with hematopoietic growth factors may be considered. Due to the frequency of neutropenia, anemia, and thrombocytopenia in patients receiving valganciclovir [see Adverse Reactions (6.1) ], complete blood counts with differential and platelet counts should be performed frequently, especially in infants, in patients …

8.1 Pregnancy Risk Summary After oral administration, valganciclovir (prodrug) is converted to ganciclovir (active drug) and, therefore, valganciclovir is expected to have reproductive toxicity effects similar to ganciclovir. In animal studies, ganciclovir caused maternal and fetal toxicity and embryo-fetal mortality in pregnant mice and rabbits as well as teratogenicity in rabbits at exposures two-times the human exposure. There are no available human data on use of valganciclovir or ganciclovir in pregnant women to establish the presence or absence of drug-associated risk. The background risk of major birth defects and miscarriage for the indicated populations is unknown. However, the …
