Pricing

A drug doesn't have one price. Each row is a different public payment system, and none is what you'd pay at the counter — that depends on your insurance. The ⓘ on each row explains what it measures.

Where does this data come from?
NADAC (National Average Drug Acquisition Cost) is the CMS weekly pharmacy-acquisition-cost survey — what pharmacies pay. ASP (Average Sales Price) is the CMS Medicare Part B drug-payment file, published quarterly. Medicaid pays is computed by us from CMS State Drug Utilization Data (total reimbursed ÷ units, trailing 12 months) — gross of rebates and inclusive of dispensing fees, so it reflects what Medicaid paid, not an acquisition cost. Medicare drug plans pay is the median negotiated point-of-sale unit cost across plans listing this NDC in the CMS quarterly Prescription Drug Plan pricing files, before rebates. The VA pays is the federal contract price (FSS, and the statutory Big 4 ceiling where listed) from the VA National Acquisition Center pharmaceutical price file. All are free public government data; each measures a different payer, so the figures are not directly comparable.

🎯 Indications and Usage 85 words ▾

1 INDICATIONS AND USAGE Valganciclovir is a deoxynucleoside analogue cytomegalovirus (CMV) DNA polymerase inhibitor indicated for: Pediatric Patients ( 1.2 ) Prevention of CMV disease in kidney and heart transplant patients at high risk.

1.2Pediatric Patients Prevention of CMV Disease: Valganciclovir for oral solution is 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 )] .

⏱️ Dosage and Administration ~3 min read ▾

2 DOSAGE AND ADMINISTRATION Pediatric Dosage ( 2.3 ) Prevention of CMV disease in kidney transplant patients 4 months to 16 years of age Dose once a day within 10 days of transplantation until 200 days post-transplantation according to dosage algorithm (note the calculation of creatinine clearance using a modified Schwartz formula in children) Prevention of CMV disease in heart transplant patients 1 month to 16 years of age Dose once a day within 10 days of transplantation until 100 days post-transplantation according to dosage algorithm (note the calculation of creatinine clearance using a modified Schwartz formula in children) Valganciclovir for oral solution should be taken with food.

( 2.1 , 12.3 ) Adult patients should use valganciclovir tablets, not valganciclovir for oral solution. ( 2.1 )

2.1General Dosing Information Adult patients should use valganciclovir tablets, not valganciclovir for oral solution. Valganciclovir for oral solution should be taken with food [see Clinical Pharmacology ( 12.3 )] . Valganciclovir for oral solution (50 mg/mL) must be prepared by the pharmacist prior to dispensing to the patient [see Dosage and Administration ( 2.4 )] .

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 (7 x BSA x CrCl) should start within 10 days of transplantation until 100 days post-transplantation.

The recommended once daily dosage of valganciclovir for oral solution 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.

Table 1 k Values According to Pediatric Patient Age* k value Pediatric Patient Age

0.33 Infants less than 1 year of age with low birth weight for gestational age

0.45 Infants less than 1 year of age with birth weight appropriate for gestational age

0.45 Children aged 1 to less than 2 years

0.55 Boys aged 2 to less than 13 years Girls aged 2 to less than 16 years

0.7Boys aged 13 to 16 years * The k values provided are based on the Jaffe method of measuring serum creatinine, and may require correction when enzymatic methods are used 1 . Monitor serum creatinine levels regularly and consider changes in height and body weight and adapt the dose as appropriate during prophylaxis period. All calculated doses should be rounded to the nearest 25 mg increment for the actual deliverable dose.

The oral dispenser is graduated in 0.5 mL increments. A 50 mg dose is equivalent to 1 mL. If the calculated dose exceeds 900 mg, a maximum dose of 900 mg should be administered.

Valganciclovir for oral solution is the preferred formulation since it provides the ability to administer a dose calculated according to the formula above; however, valganciclovir tablets may be used if the calculated doses are within 10% of available tablet strength (450 mg). For example, if the calculated dose is between 405 mg and 495 mg, one 450 mg tablet may be taken. Before prescribing valganciclovir tablets, pediatric patients should be assessed for the ability to swallow tablets. valganciclovir-equ.jpg

4 CONTRAINDICATIONS Valganciclovir for oral solution 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 ~3 min read ▾

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. ( 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 for oral solution 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 for oral solution 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 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 T… [Excerpted — this section continues on DailyMed.]

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 for oral solution or tablets are diarrhea, pyrexia, upper respiratory tract infection, urinary tract infection, vomiting, neutropenia, leukopenia, and headache. 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.

( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact Micro Labs USA Inc., at 1-855-839-8195 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch.

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 pooled selected adverse reactions and abnormal laboratory values from these patients.

🔄 Drug Interactions ~2 min read ▾

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 co-administered drug. Therefore, these patients should be closely monitored for toxicity of ganciclovir and the co-administered 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 Co-administration 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 co-administered 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, co-administration 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 co-administered with valganciclovir, the risk of nephrotoxicity may be increased. Monitor renal function.

( 5.2 , 7 ) Mycophenolate mofetil (MMF): When co-administered 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 co-administered 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 )

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 ~3 min read ▾

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 to 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 to 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 162 words ▾

8.5Geriatric Use Studies of valganciclovir for oral solution or 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 Warnings and Precautions ( 5.2 ), Use in Specific Populations ( 8.6 ), Clinical Pharmacology ( 12.3 )].

🆘 Overdosage 160 words ▾

10 OVERDOSAGE Experience with Valganciclovir Tablets: An overdose of valganciclovir could possibly result in increased renal toxicity [see 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 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 ~2 min read ▾

17 PATIENT COUNSELING INFORMATION Advise the patient to read the FDA-approved patient labeling (Patient Information and Instructions for Use). 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 )] .

8.3Females and Males of Reproductive Potential Pregnancy Testing Females of reproductive potential should undergo pregnancy testing before initiation of valganciclovir [see Use in Specific Populations ( 8.1 )] . Contraception Females Because of the mutagenic and teratogenic potential of valganciclovir, females of reproductive potential should be advised to use effective contraception during treatment and for at least 30 days following treatment with valganciclovir [see Dosage and Administration ( 2.6 ), Warnings and Precautions ( 5.4 , 5.5 ), Nonclinical Toxicology ( 13.1 )] .

Males Because of its mutagenic potential, males should be advised to use condoms during and for at least 90 days following, treatment with valganciclovir [see Dosage and Administration ( 2.6 ), Warnings and Precautions ( 5.3 , 5.5 ), Nonclinical Toxicology ( 13.1 )]. Infertility Valganciclovir at the recommended doses may cause temporary or permanent female and male infertility [see Warnings and Precautions ( 5.3 ), Nonclinical Toxicology ( 13.1 )]. Data Human Data In a small, open-label, non-randomized clinical study, adult male renal transplant patients receiving valganciclovir for CMV prophylaxis for up to 200 days post-transplantation were compared to an untreated control group.

Patients were followed-up for six months after valganciclovir discontinuation. Among 24 evaluable patients in the valganciclovir group, the mean sperm density at the end of treatment visit decreased by 11 million/mL from baseline; whereas, among 14 evaluable patients in the control group the mean sperm density increased by 33 million/mL. However, at the follow-up visit among 20 evaluable patients in the valganciclovir group the mean sperm density was comparable to that observed among 10 evaluable patients in the untreated control group (the mean sperm density at the end of follow-up visit increased by 41 million/mL from baseline in the valganciclovir group and by 43 million/mL in the untreated group).

14 CLINICAL STUDIES

14.2Pediatric Patients Prevention of CMV in Pediatric Heart, Kidney, or Liver Transplantation : Sixty-three children, 4 months to 16 years of age, who had a solid organ transplant (kidney 33, liver 17, heart 12, and kidney/liver 1) and were at risk for developing CMV disease, were enrolled in an open-label, safety, and pharmacokinetic study of oral valganciclovir (valganciclovir for oral solution or tablets). Patients received valganciclovir once daily within 10 days after transplant until a maximum of 100 days post-transplant.

The daily doses of valganciclovir were calculated at each study visit based on body surface area and a modified creatinine clearance [ see Dosage and Administration ( 2.3 ) ]. The pharmacokinetics of ganciclovir were similar across organ transplant types and age ranges. The mean daily ganciclovir exposures in pediatric patients were somewhat increased relative to those observed in adult solid organ transplant patients receiving valganciclovir 900 mg once daily, but were within the range considered safe and effective in adults [ see Clinical Pharmacology ( 12.3 ) ].

No case of CMV syndrome or tissue-invasive CMV disease was reported within the first six months post-transplantation. Prevention of CMV in Pediatric Kidney Transplantation: Fifty-seven children, 1 to 16 years of age, who had a renal transplant and were at risk for developing CMV disease, were enrolled in an open-label tolerability study of oral valganciclovir (valganciclovir for oral solution or tablets). Patients received valganciclovir once daily within 10 days after transplant until a maximum of 200 days post-transplant.

The daily doses of valganciclovir were calculated at each study visit based on body surface area and a modified creatinine clearance [ see Dosage and Administration ( 2.3 ) ]. No case of CMV syndrome or tissue-invasive CMV disease was reported within the first 12 months post-transplantation.

13 NONCLINICAL TOXICOLOGY

13.1Carcinogenesis, Mutagenesis, Impairment of Fertility Long-term carcinogenicity studies have not been conducted with valganciclovir. However, upon oral administration, valganciclovir is rapidly and extensively converted to ganciclovir. Therefore, like ganciclovir, valganciclovir is a potential carcinogen.

Ganciclovir was carcinogenic in the mouse at oral doses that produced exposures approximately 0.1x and 1.4x, respectively, the mean drug exposure in humans following the recommended intravenous dose of 5 mg/kg, based on area under the plasma concentration curve (AUC) comparisons. At the higher dose, there was a significant increase in the incidence of tumors of the preputial gland in males, forestomach (nonglandular mucosa) in males and females, and reproductive tissues (ovaries, uterus, mammary gland, clitoral gland and vagina) and liver in females.

At the lower dose, a slightly increased incidence of tumors was noted in the preputial and harderian glands in males, forestomach in males and females, and liver in females. Ganciclovir should be considered a potential carcinogen in humans. Valganciclovir increases mutations in mouse lymphoma cells.

In the mouse micronucleus assay, valganciclovir was clastogenic. Valganciclovir was not mutagenic in the Ames Salmonella assay. Ganciclovir increased mutations in mouse lymphoma cells and DNA damage in human lymphocytes in vitro .

In the mouse micronucleus assay, ganciclovir was clastogenic. Ganciclovir was not mutagenic in the Ames Salmonella assay. Valganciclovir is converted to ganciclovir and therefore is expected to have similar reproductive toxicity effects as ganciclovir [ see Warnings and Precautions (5.3) ].

Ganciclovir caused decreased mating behavior, decreased fertility, and an increased incidence of embryolethality in female mice following intravenous doses that produced an exposure approximately 1.7x the mean drug exposure in humans following the dose of 5 mg per kg, based on AUC comparisons. Ganciclovir caused decreased fertility in male mice and hypospermatogenesis in mice and dogs following daily oral or intravenous administration. Systemic drug exposure (AUC) at the lowest dose showing toxicity in each species ranged from 0.03 to 0.1x the AUC of the recommended human intravenous dose.

Valganciclovir caused similar effects on spermatogenesis in mice, rats, and dogs. These effects were reversible at lower doses but irreversible at higher doses. It is considered likely that ganciclovir (and valganciclovir) could cause temporary or permanent inhibition of human spermatogenesis.

13.1Carcinogenesis, Mutagenesis, Impairment of Fertility Long-term carcinogenicity studies have not been conducted with valganciclovir. However, upon oral administration, valganciclovir is rapidly and extensively converted to ganciclovir. Therefore, like ganciclovir, valganciclovir is a potential carcinogen.

Ganciclovir was carcinogenic in the mouse at oral doses that produced exposures approximately 0.1x and 1.4x, respectively, the mean drug exposure in humans following the recommended intravenous dose of 5 mg/kg, based on area under the plasma concentration curve (AUC) comparisons. At the higher dose, there was a significant increase in the incidence of tumors of the preputial gland in males, forestomach (nonglandular mucosa) in males and females, and reproductive tissues (ovaries, uterus, mammary gland, clitoral gland and vagina) and liver in females.

At the lower dose, a slightly increased incidence of tumors was noted in the preputial and harderian glands in males, forestomach in males and females, and liver in females. Ganciclovir should be considered a potential carcinogen in humans. Valganciclovir increases mutations in mouse lymphoma cells.

Questions about this listing

Why is there no price listed?
The pricing shown on our NDC pages comes from CMS NADAC, a voluntary survey of retail community pharmacy invoices. CMS does not publish a NADAC for every NDC — packages outside the retail survey (institutional and hospital products, bulk packages, discontinued items, and many OTC items) may never receive one. A missing price reflects the survey's scope, not this product's actual cost, and does not mean the product is free or unavailable.
Is the NDC printed on the package the same as the 11-digit billing NDC?
Yes, they identify this exact package in different formats. The form printed on the packaging and shown on DailyMed is the one the FDA registered. Insurance claims use a fixed 11-digit 5-4-2 format, so the short segment is padded with a leading zero and the dashes are dropped. The Identity section at the top of this page lists each form of this code.
Is this package still being marketed?
Yes, per the latest FDA NDC Directory data on this page: this package is listed as actively marketed, with no marketing end date reported by Micro Labs Limited. Listing status can change — the directory data on this page refreshes weekly.
Who lists this product with the FDA?
Micro Labs Limited is the labeler of record for this NDC — the company under whose FDA-assigned code the package is listed. The labeler may be the manufacturer itself or a distributor marketing the product under its own code.
