Valganciclovir tablets should not be broken or crushed (2.6) . Adult patients should use valganciclovir tablets, not valganciclovir for oral solution (2.1) . Adults with renal impairment: Adjust dose based on creatinine clearance.
For adult patients receiving hemodialysis a dose recommendation cannot be given (2.5 , 8.6 , 12.3) .
2.1General Dosing Information Adult patients should use valganciclovir tablets, not valganciclovir for oral solution. Valganciclovir tablets should be taken with food [see Clinical Pharmacology (12.3) ].
2.2Recommended Dosage in Adult Patients with Normal Renal Function For dosage recommendations in adult patients with renal impairment [see Dosage and Administration (2.5) ]. Treatment of CMV Retinitis: Induction: The recommended dosage is 900 mg (two 450 mg tablets) taken orally twice a day for 21 days. Maintenance: Following induction treatment, or in adult patients with inactive CMV retinitis, the recommended dosage is 900 mg (two 450 mg tablets) taken orally once a day.
Prevention of CMV Disease: For adult patients who have received a heart or kidney-pancreas transplant, the recommended dosage is 900 mg (two 450 mg tablets) taken orally once a day starting within 10 days of transplantation until 100 days post-transplantation. For adult patients who have received a kidney transplant, the recommended dosage is 900 mg (two 450 mg tablets) taken orally once a day starting within 10 days of transplantation until 200 days post-transplantation.
2.3Recommended Dosage in Pediatric Patients Prevention of CMV Disease in Pediatric Kidney Transplant Patients: For pediatric kidney transplant patients 4 months to 16 years of age, the recommended once daily mg dose (7 x BSA x CrCl) should start within 10 days of post-transplantation until 200 days post-transplantation. Prevention of CMV Disease in Pediatric Heart Transplant Patients: For pediatric heart transplant patients 1 month to 16 years of age, the recommended once daily mg dose (7x BSA x CrCl) should start within 10 days of transplantation until 100 days post-transplantation.
The recommended once daily dosage of valganciclovir tablets is based on body surface area (BSA) and creatinine clearance (CrCl) derived from a modified Schwartz formula, and is calculated using the equation below: Pediatric Dose (mg) = 7 x BSA x CrCl (calculated using a modified Schwartz formula). If the calculated Schwartz creatinine clearance exceeds 150 mL/min/1.73m 2 , then a maximum value of 150 mL/min/1.73m 2 should be used in the equation. The k values used in the modified Schwartz formula are based on pediatric patient age, as shown in Table 1 .

💊 Dosage Forms and Strengths ▾
3 DOSAGE FORMS AND STRENGTHS Valganciclovir Tablets, USP 450 mg are pink colored, oval shaped, film coated tablets debossed with ‘RDY’ on one side and ‘762’ on other side. Tablets: 450 mg (3)
⛔ Contraindications ▾
4 CONTRAINDICATIONS 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)
⚠️ Warnings and Cautions ▾
5 WARNINGS AND PRECAUTIONS 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) .
5.1Hematologic 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 with renal impairment and in patients in whom ganciclovir or other nucleoside analogues have previously resulted in leukopenia, or in whom neutrophil counts are less than 1000 cells/μL at the beginning of treatment. Increased monitoring for cytopenias may be warranted if therapy with oral ganciclovir is changed to valganciclovir, because of increased plasma concentrations of ganciclovir after valganciclovir administration [see Clinical Pharmacology (12.3) ].
5.2Acute Renal Failure Acute renal failure may occur in: Elderly patients with or without reduced renal function. Caution should be exercised when administering valganciclovir to geriatric patients, and dosage reduction is recommended for those with impaired renal function [see Dosage and Administration (2.5) , Use in Specific Populations (8.5 , 8.6) ]. Patients receiving potential nephrotoxic drugs.
Caution should be exercised when administering valganciclovir to patients receiving potential nephrotoxic drugs. Patients without adequate hydration. Adequate hydration should be maintained for all patients.
5.3Impairment of Fertility Based on animal data and limited human data, valganciclovir at the recommended human doses may cause temporary or permanent inhibition of spermatogenesis in males, and may cause suppression of fertility in females. Advise patients that fertility may be impaired with use of valganciclovir [see Use in Specific Populations (8.1 , 8.3) , Nonclinical Toxicology (13.1) ].
5.4Fetal Toxicity Ganciclovir may cause fetal toxicity when administered to pregnant women based on findings in animal studies. When given to pregnant rabbits at dosages resulting in 2 times the human exposure (based on AUC), ganciclovir caused malformations in multiple organs of the fetuses. Maternal and fetal toxicity were also observed in pregnant mice and rabbits.
Therefore, valganciclovir has the potential to cause birth defects. Pregnancy should be avoided in female patients taking valganciclovir and in females with male partners taking valganciclovir. Females of reproductive potential should be advised to use effective contraception during treatment and for at least 30 days following treatment with valganciclovir because of the potential risk to the fetus.
Similarly, males should be advised to use condoms during and for at least 90 days following treatment with valganciclovir [see Dosage and Administration (2.6) , Use in Specific Populations (8.1 , 8.3) , Nonclinical Toxicology…

6 ADVERSE REACTIONS The following serious adverse reactions are discussed in greater detail in other sections of the labeling: Hematologic Toxicity [see Warnings and Precautions (5.1) ]. Acute Renal Failure [see Warnings and Precautions (5.2) ]. Impairment of Fertility [see Warnings and Precautions (5.3) ].
Fetal Toxicity [see Warnings and Precautions (5.4) ]. Mutagenesis and Carcinogenesis [see Warnings and Precautions (5.5) ]. The most common adverse reactions and laboratory abnormalities reported in at least one indication by greater than or equal to 20% of adult patients treated with valganciclovir tablets are diarrhea, pyrexia, fatigue, nausea, tremor, neutropenia, anemia, leukopenia, thrombocytopenia, headache, insomnia, urinary tract infection, and vomiting.
The most common reported adverse reactions and laboratory abnormalities reported in greater than or equal to 20% of pediatric solid organ transplant recipients treated with valganciclovir tablets are diarrhea, pyrexia, upper respiratory tract infection, urinary tract infection, vomiting, neutropenia, leukopenia, and headache. Adult patients: Most common adverse reactions and laboratory abnormalities (reported in at least one indication by greater than or equal to 20% of patients) are diarrhea, pyrexia, fatigue, nausea, tremor, neutropenia, anemia, leukopenia, thrombocytopenia, headache, insomnia, urinary tract infection, and vomiting.
(6.1) Pediatric patients: Most common adverse reactions and laboratory abnormalities (reported in greater than or equal to 20% of pediatric solid organ transplant recipients) are diarrhea, pyrexia, upper respiratory tract infection, urinary tract infection, vomiting, neutropenia, leukopenia, and headache.

6.1Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect rates observed in practice. Valganciclovir, a prodrug of ganciclovir, is rapidly converted to ganciclovir after oral administration. Adverse reactions known to be associated with ganciclovir usage can therefore be expected to occur with valganciclovir.
Adverse Reactions in Adults Treatment of CMV Retinitis in AIDS Patients: In a clinical study for the treatment of CMV retinitis in HIV-infected patients, the adverse reactions reported by patients receiving valganciclovir tablets (n=79) or intravenous ganciclovir (n=79) for 28 days of randomized therapy (21 days induction dose and 7 days maintenance dose), respectively, included diarrhea (16%, 10%), nausea (8%, 14%), and headache (9%, 5%). The incidence of adverse reactions was similar between the group who received valganciclovir tablets and the group who received intravenous ganciclovir.
The frequencies of neutropenia (ANC less than 500/μL) were 11% for patients receiving valganciclovir tablets compared with 13% for patients receiving intravenous ganciclovir. Anemia (Hgb less than 8 g/dL) occurred in 8% of patients in each group. Other laboratory abnormalities occurred with similar frequencies in the two groups.
Adverse reactions and laboratory abnormalities are available for 370 patients who received maintenance therapy with valganciclovir tablets 900 mg once daily in two open-label clinical trials. Approximately 252 (68%) of these patients received valganciclovir tablets for more than nine months (maximum duration was 36 months). Table 3 and Table 4 show the pooled selected adverse reactions and abnormal laboratory values from these patients.

🔄 Drug Interactions ▾
7 DRUG INTERACTIONS In vivo drug-drug interaction studies were not conducted with valganciclovir. However, because valganciclovir is rapidly and extensively converted to ganciclovir, drug-drug interactions associated with ganciclovir will be expected for valganciclovir. Drug-drug interaction studies with ganciclovir were conducted in patients with normal renal function.
Following concomitant administration of valganciclovir and other renally excreted drugs, patients with impaired renal function may have increased concentrations of ganciclovir and the coadministered drug. Therefore, these patients should be closely monitored for toxicity of ganciclovir and the coadministered drug. Established and other potentially significant drug interactions conducted with ganciclovir are listed in Table 9 .
Table 9 Established and Other Potentially Significant Drug Interactions with Ganciclovir Name of the Concomitant Drug Change in the Concentration of Ganciclovir or Concomitant Drug Clinical Comment Imipenem-cilastatin Unknown Coadministration with imipenem-cilastatin is not recommended because generalized seizures have been reported in patients who received ganciclovir and imipenem-cilastatin. Cyclosporine or amphotericin B Unknown Monitor renal function when valganciclovir is coadministered with cyclosporine or amphotericin B because of potential increase in serum creatinine [see Warnings and Precautions (5.2) ].
Mycophenolate mofetil (MMF) ↔ Ganciclovir (in patients with normal renal function) ↔ MMF (in patients with normal renal function) Based on increased risk, patients should be monitored for hematological and renal toxicity. Other drugs associated with myelosuppression or nephrotoxicity (e.g., adriamycin, dapsone, doxorubicin, flucytosine, hydroxyurea, pentamidine, tacrolimus, trimethoprim/ sulfamethoxazole, vinblastine, vincristine, and zidovudine) Unknown Because of potential for higher toxicity, coadministration with valganciclovir should be considered only if the potential benefits are judged to outweigh the risks.
Didanosine ↔ Ganciclovir ↑ Didanosine Patients should be closely monitored for didanosine toxicity (e.g., pancreatitis) Probenecid ↑ Ganciclovir Valganciclovir dose may need to be reduced. Monitor for evidence of ganciclovir toxicity. Imipenem-cilastatin: Seizures were reported in patients receiving ganciclovir and imipenem-cilastatin.
Concomitant use is not recommended unless the potential benefits outweigh the risks. (7) Cyclosporine or amphotericin B: When coadministered with valganciclovir, the risk of nephrotoxicity may be increased. Monitor renal function.
(5.2 , 7) Mycophenolate mofetil (MMF): When coadministered with valganciclovir, the risk of hematological and renal toxicity may be increased. Monitor for ganciclovir and MMF toxicity. (7) Other drugs associated with myelosuppression or nephrotoxicity: Due to potential for increased toxicity, consider for concomitant use with valganciclovir only if the potential benefits are judged to outweigh the risks.
(7) Didanosine: Ganciclovir coadministered with didanosine may increase didanosine levels. Monitor for didanosine toxicity (e.g., pancreatitis). (7) Probenecid: May increase ganciclovir levels.
Monitor for evidence of ganciclovir toxicity. (7)
👥 Use in Specific Populations ▾
8 USE IN SPECIFIC POPULATIONS Lactation: Breastfeeding is not recommended with use of valganciclovir. (8.2)
8.1Pregnancy 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 background risk in the U.S. general population of major birth defects is 2 to 4% and the risk of miscarriage is 15 to 20% of clinically recognized pregnancies. Advise pregnant women of the potential risk to the fetus [see Warnings and Precautions (5.3) , Use in Specific Populations (8.3) ].
Clinical Considerations Disease-associated maternal and/or embryo/fetal risk Most maternal CMV infections are asymptomatic or they may be associated with a self-limited mononucleosis-like syndrome. However, in immunocompromised patients (i.e., transplant patients or patients with AIDS) CMV infections may be symptomatic and may result in significant maternal morbidity and mortality. The transmission of CMV to the fetus is a result of maternal viremia and transplacental infection.
Perinatal infection can also occur from exposure of the neonate to CMV shedding in the genital tract. Approximately 10% of children with congenital CMV infection are symptomatic at birth. Mortality in these infants is about 10% and approximately 50 to 90% of symptomatic surviving newborns experience significant morbidity, including mental retardation, sensorineural hearing loss, microcephaly, seizures, and other medical problems.
The risk of congenital CMV infection resulting from primary maternal CMV infection may be higher and of greater severity than that resulting from maternal reactivation of CMV infection. Data Animal Data Doses resulting in two-times the human exposure of ganciclovir (based on the human AUC following a single intravenous infusion of 5 mg per kg of ganciclovir) resulted in maternal and embryo-fetal toxicity in pregnant mice and rabbits as well as teratogenicity in the rabbits. Fetal resorptions were present in at least 85% of rabbits and mice.
Rabbits showed increased embryo-fetal mortality, growth retardation of the fetuses and structural abnormalities of multiple organs of the fetuses including the palate (cleft palate), eyes (anophthalmia/microphthalmia), brain (hydrocephalus), jaw (brachygnathia), kidneys and pancreas (aplastic organs). Increased embryo-fetal mortality was also seen in mice. Daily intravenous doses of approximately 1.7 times the human exposure (based on AUC) administered to female mice prior to mating, during gestation, and during lactation caused hypoplasia of the testes and seminal vesicles in the male offspring, as well as pathologic changes in the nonglandular region of the stomach.
Data from an ex-vivo human placental model showed that ganciclovir crosses the human placenta. The transfer occurred by passive diffusion and was not saturable over a concentration range of 1 to 10 mg/mL.
8.2Lactation Risk Summary No data are available regarding the presence of valganciclovir (prodrug) or ganciclovir (active drug) in human milk, the effects on the breastfed infant, or the effects on milk production. Animal data indicate that ganciclovir is excreted in the milk of lactating rats. The Centers for Disease Control and Prevention recommend that HIV-infected mothers not breastfeed their infants to avoid risking postnatal transmission of HIV.

🧒 Pediatric Use ▾
8.4Pediatric Use Valganciclovir for oral solution and tablets are indicated for the prevention of CMV disease in pediatric kidney transplant patients 4 months to 16 years of age and in pediatric heart transplant patients 1 month to 16 years of age at risk for developing CMV disease [see Indications and Usage (1.2) , Dosage and Administration (2.3) ]. The use of valganciclovir for oral solution and tablets for the prevention of CMV disease in pediatric kidney transplant patients 4 months to 16 years of age is based on two single-arm, open-label, non-comparative studies in patients 4 months to 16 years of age.
Study 1 was a safety and pharmacokinetic study in pediatric solid organ transplant patients (kidney, liver, heart, and kidney/pancreas). Valganciclovir was administered once daily within 10 days of transplantation for a maximum of 100 days post-transplantation. Study 2 was a safety and tolerability study where valganciclovir was administered once daily within 10 days of transplantation for a maximum of 200 days post-transplantation in pediatric kidney transplant patients.
The results of these studies were supported by previous demonstration of efficacy in adult patients [see Adverse Reactions (6.1) , Clinical Pharmacology (12.3) , Clinical Studies (14.2) ]. The use of valganciclovir for oral solution and tablets for the prevention of CMV disease in pediatric heart transplant patients 1 month to 16 years of age is based on two studies (Study 1 described above and Study 3) and was supported by previous demonstration of efficacy in adult patients [see Clinical Pharmacology (12.3) , Clinical Studies (14.2) ].
Study 3 was a pharmacokinetic and safety study of valganciclovir in pediatric heart transplant patients less than 4 months of age who received a single dose of valganciclovir oral solution on each of two consecutive days. A physiologically based pharmacokinetic (PBPK) model was developed based on the available pharmacokinetic data from pediatric and adult patients to support dosing in heart transplant patients less than 1 month of age. However, due to uncertainty in model predictions for neonates, valganciclovir is not indicated for prophylaxis in this age group.
The safety and efficacy of valganciclovir for oral solution and tablets have not been established in children for prevention of CMV disease in pediatric liver transplant patients, in kidney transplant patients less than 4 months of age, in heart transplant patients less than 1 month of age, in pediatric AIDS patients with CMV retinitis, and in infants with congenital CMV infection. A pharmacokinetic and pharmacodynamic evaluation of valganciclovir for oral solution was performed in 24 neonates with congenital CMV infection involving the central nervous system.
All patients were treated for 6 weeks with a combination of intravenous ganciclovir 6 mg per kg twice daily or valganciclovir for oral solution at doses ranging from 14 mg per kg to 20 mg per kg twice daily. The pharmacokinetic results showed that in infants greater than 7 days to 3 months of age, a dose of 16 mg per kg twice daily of valganciclovir for oral solution provided ganciclovir systemic exposures (median AUC 0-12h = 23.6 [range 16.8 to 35.5] mcg∙h/mL; n = 6) comparable to those obtained in infants up to 3 months of age from a 6 mg per kg dose of intravenous ganciclovir twice daily (AUC 0-12h = 25.3 [range 2.4 to 89.7] mcg∙h/mL; n = 18) or to the ganciclovir systemic exposures obtained in adults from a 900 mg dose of valganciclovir tablets twice daily.
However, the efficacy and safety of intravenous ganciclovir and of valganciclovir have not been established for the treatment of congenital CMV infection in infants and no similar disease occurs in adults; therefore, efficacy cannot be extrapolated from intravenous ganciclovir use in adults.
🧓 Geriatric Use ▾
8.5Geriatric Use Studies of valganciclovir tablets have not been conducted in adults older than 65 years of age. Clinical studies of valganciclovir did not include sufficient numbers of subjects aged 65 and over to determine whether they respond differently from younger subjects. In general, dose selection for an elderly patient should be cautious, usually starting at the low end of the dosing range, reflecting the greater frequency of decreased hepatic, renal, or cardiac function, and of concomitant disease or other drug therapy.
Valganciclovir is known to be substantially excreted by the kidneys, and the risk of toxic reactions to this drug may be greater in patients with impaired renal function. Because renal clearance decreases with age, valganciclovir should be administered with consideration of their renal status. Renal function should be monitored and dosage adjustments should be made accordingly [see Dosage and Administration (2.5) , Warnings and Precautions (5.2) , Use in Specific Populations (8.6) , Clinical Pharmacology (12.3) ].
🆘 Overdosage ▾
10 OVERDOSAGE Experience with Valganciclovir Tablets: An overdose of valganciclovir could also possibly result in increased renal toxicity [see Dosage and Administration (2.5) , Use in Specific Populations (8.6) ]. Because ganciclovir is dialyzable, dialysis may be useful in reducing serum concentrations in patients who have received an overdose of valganciclovir [see Clinical Pharmacology (12.3) ]. Adequate hydration should be maintained.
The use of hematopoietic growth factors should be considered [see Warnings and Precautions (5.1) and see Clinical Pharmacology (12.3) ]. Reports of adverse reactions after overdoses with valganciclovir, some with fatal outcomes, have been received from clinical trials and during postmarketing experience. The majority of patients experienced one or more of the following adverse events: Hematological toxicity: myelosuppression including pancytopenia, bone marrow failure, leukopenia, neutropenia, granulocytopenia Hepatotoxicity: hepatitis, liver function disorder Renal toxicity: worsening of hematuria in a patient with pre-existing renal impairment, acute kidney injury, elevated creatinine Gastrointestinal toxicity: abdominal pain, diarrhea, vomiting Neurotoxicity: generalized tremor, seizure

💬 Information for Patients ▾
17 PATIENT COUNSELING INFORMATION Advise the patient to read the FDA-approved patient labeling (Patient Information) . Serious Adverse Reactions Inform patients that valganciclovir may cause granulocytopenia (neutropenia), anemia, thrombocytopenia and elevated creatinine levels and that dose modification or discontinuation of dosing may be required. Complete blood counts, platelet counts, and creatinine levels should be monitored frequently during treatment [see Warnings and Precautions (5.1) ].
Pregnancy and Contraception Inform females of reproductive potential that valganciclovir causes birth defects in animals. Advise them to use effective contraception during and for at least 30 days following treatment with valganciclovir. Similarly, advise males to use condoms during and for at least 90 days following treatment with valganciclovir [see Use in Specific Populations (8.1 , 8.3) ].
Carcinogenicity Advise patients that valganciclovir is considered a potential carcinogen [see Nonclinical Toxicity (13.1) ]. Lactation Advise mothers not to breast-feed if they are receiving valganciclovir because of the potential for hematologic toxicity and cancer in nursing infants, and because HIV can be passed to the baby in breast milk [see Use in Specific Populations (8.2) ]. Infertility Advise patients that valganciclovir may cause temporary or permanent female and male infertility [see Warnings and Precautions (5.3) , Use in Specific Populations (8.3) ].
Impairment of Cognitive Ability Inform patients that tasks requiring alertness may be affected including the patient’s ability to drive and operate machinery as seizures, dizziness, and/or confusion have been reported with the use of valganciclovir [see Adverse Reactions (6.1) ]. Use in Patients with CMV Retinitis Inform patients that valganciclovir is not a cure for CMV retinitis, and they may continue to experience progression of retinitis during or following treatment. Advise patients to have ophthalmologic follow-up examinations at a minimum of every 4 to 6 weeks while being treated with valganciclovir.
Some patients will require more frequent follow-up. Administration Inform adult patients that they should use valganciclovir tablets, not valganciclovir for oral solution [see Dosage and Administration (2.1) ]. Inform patients to take valganciclovir tablets with food to maximize bioavailability.
