Quick answers
  • RxCUI (RxNorm): 198377
Why two NDCs? The FDA registers this code as 55154-4168-0 — a 5-4-1 layout, and that's what's printed on the package and shown on DailyMed. For insurance claims, every NDC is standardized to a uniform 11-digit 5-4-2 format by adding a zero to the package segment → 55154-4168-00. Same drug, same package — only the format differs.

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.

1 INDICATIONS AND USAGE Tacrolimus capsule is a calcineurin-inhibitor immunosuppressant indicated for the prophylaxis of organ rejection in adult patients receiving allogeneic liver, kidney, heart transplants, and pediatric patients receiving allogeneic liver transplants, in combination with other immunosuppressants. (1.1)

1.1Prophylaxis of Organ Rejection in Kidney, Liver, or Heart Transplant Tacrolimus capsules are indicated for the prophylaxis of organ rejection, in adult patients receiving allogeneic kidney transplant [see Clinical Studies (14.1)], liver transplant [see Clinical Studies (14.2)] or heart transplant [see Clinical Studies (14.3)] and pediatric patients receiving allogeneic liver transplant [see Clinical Studies (14.2)] in combination with other immunosuppressants.

⏱️ Dosage and Administration ~3 min read ▾

2 DOSAGE AND ADMINISTRATION • Intravenous (IV) use recommended for patients who cannot tolerate oral formulations (capsules). (2.1, 2.2) • Administer capsules consistently with or without food. (2.1) • Therapeutic drug monitoring is recommended.

(2.1, 2.6) • Avoid eating grapefruit or drinking grapefruit juice. (2.1) • See dosage adjustments for African-American patients (2.2), hepatic and renal impaired. (2.4, 2.5) • For complete dosing information, see Full Prescribing Information.

MMF = Mycophenolate mofetil 1. Patients with cystic fibrosis may require higher doses due to lower bioavailability. 2.

2.1Important Administration Instructions Tacrolimus capsules should not be used without supervision by a physician with experience in immunosuppressive therapy. Tacrolimus capsules are not interchangeable or substitutable for other tacrolimus extended-release products. This is because rate of absorption following the administration of an extended-release tacrolimus product is not equivalent to that of an immediate-release tacrolimus drug product.

Under- or overexposure to tacrolimus may result in graft rejection or other serious adverse reactions. Changes between tacrolimus immediate-release and extended-release dosage forms must occur under physician supervision [see Warnings and Precautions (5.3)]. Oral Formulation (Capsules) If patients are able to initiate oral therapy, the recommended starting doses should be initiated.

Tacrolimus capsules may be taken with or without food. However, since the presence of food affects the bioavailability of Tacrolimus, if taken with food, it should be taken consistently the same way each time [see Clinical Pharmacology (12.3)]. General Administration Instructions Patients should not eat grapefruit or drink grapefruit juice in combination with Tacrolimus capsules [see Drug Interactions (7.2)].

Tacrolimus capsules should not be used simultaneously with cyclosporine. Tacrolimus capsules or cyclosporine should be discontinued at least 24 hours before initiating the other. In the presence of elevated Tacrolimus capsules or cyclosporine concentrations, dosing with the other drug usually should be further delayed.

Therapeutic drug monitoring (TDM) is recommended for all patients receiving Tacrolimus capsules [see Dosage and Administration (2.6)].

2.2Dosage Recommendations for Adult Kidney, Liver, or Heart Transplant Patients - Capsules Capsules If patients are able to tolerate oral therapy, the recommended oral starting doses should be initiated. The initial dose of tacrolimus capsules should be administered no sooner than 6 hours after transplantation in the liver, or heart transplant patients. In kidney transplant patients, the initial dose of tacrolimus capsules may be administered within 24 hours of transplantation, but should be delayed until renal function has recovered.

The initial oral tacrolimus capsule dosage recommendations for adult patients with kidney, liver, or heart transplants and whole blood trough concentration range are shown in Table 1. Perform therapeutic drug monitoring (TDM)… [Excerpted — this section continues on DailyMed.]

Tacrolimus injection is contraindicated in patients with a hypersensitivity to HCO-60 (polyoxyl 60 hydrogenated castor oil).

Hypersensitivity symptoms reported include dyspnea, rash, pruritus, and acute respiratory distress syndrome [see Adverse Reactions ( 6 ))] .

⚠️ Warnings and Cautions ~2 min read ▾

5 WARNINGS AND PRECAUTIONS • Not Interchangeable with Extended-Release Tacrolimus Products-Medication Errors: Instruct patients or caregivers to recognize the appearance of tacrolimus capsules. (5.3) • New Onset Diabetes After Transplant: Monitor blood glucose. (5.4) • Nephrotoxicity (acute and/or chronic): Reduce the dose; use caution with other nephrotoxic drugs.

(5.5) • Neurotoxicity: Including risk of Posterior Reversible Encephalopathy Syndrome (PRES); monitor for neurologic abnormalities; reduce or discontinue tacrolimus. (5.6) • Hyperkalemia: Monitor serum potassium levels. Consider carefully before using with other agents also associated with hyperkalemia.

(5.7) • Hypertension: May require antihypertensive therapy. Monitor relevant drug-drug interactions. (5.8) • Anaphylactic Reactions with IV formulation: Observe patients receiving tacrolimus injection for signs and symptoms of anaphylaxis.

(5.9) • Not recommended for use with sirolimus: Not recommended in liver and heart transplant due to increased risk of serious adverse reactions. (5.10) • Myocardial Hypertrophy: Consider dose reduction/discontinuation. (5.13) • Immunizations: Avoid live vaccines.

(5.14) • Pure Red Cell Aplasia: Consider discontinuation of tacrolimus. (5.15) • Thrombotic Microangiopathy, Including Hemolytic Uremic Syndrome and Thrombotic Thrombocytopenic Purpura: May occur, especially in patients with infections and certain concomitant medications. (5.16)

5.1Lymphoma and Other Malignancies Patients receiving immunosuppressants, including tacrolimus, are at increased risk of developing lymphomas and other malignancies, particularly of the skin. The risk appears to be related to the intensity and duration of immunosuppression rather than to the use of any specific agent. As usual for patients with increased risk for skin cancer, examine patients for skin changes; exposure to sunlight and UV light should be limited by wearing protective clothing and using a broad-spectrum sunscreen with a high protection factor.

Post-transplant lymphoproliferative disorder (PTLD) has been reported in immunosuppressed organ transplant recipients. The majority of PTLD events appear related to Epstein-Barr Virus (EBV) infection. The risk of PTLD appears greatest in those individuals who are EBV seronegative, a population which includes many young children.

Monitor EBV serology during treatment.

5.2Serious Infections Patients receiving immunosuppressants, including tacrolimus, are at increased risk of developing bacterial, viral, fungal, and protozoal infections, including opportunistic infections. These infections may lead to serious, including fatal, outcomes. Serious viral infections reported include: • Polyomavirus-associated nephropathy (PVAN), mostly due to BK virus infection • JC virus-associated progressive multifocal leukoencephalopathy (PML) • Cytomegalovirus infections: CMV seronegative transplant patients who receive an organ from a CMV seropositive donor disease are at higher risk of developing CMV viremia and CMV disease.

Monitor for the development of infection and adjust the immunosuppressive regimen to balance the risk of rejection with the risk of infection [see Adverse Reactions (6.1, 6.2)].

5.3Not Interchangeable with Extended-Release Tacrolimus Products - Medication Errors Medication errors, including substitution and dispensing errors, between tacrolimus immediate-release products and tacrolimus extended-release products were reported outside the U.S. This led to serious adverse reactions, including graft rejection, or other adverse reactions due to under- or overexposure to tacrolimus. Tacrolimus is not interchangeable or substitutable for tacrolimus extended-release products.

Changes between tacrolimus immediate-release and extended-release dosage forms must occur under physician supervision. Instruct patients and caregivers to recognize the appearance of tacrolimus dosage forms [see Dosage Forms and Strengths (3)] and to confirm with the health… [Excerpted — this section continues on DailyMed.]

The following serious and otherwise important adverse drug reactions are discussed in greater detail in other sections of labeling: • Lymphoma and Other Malignancies [see Warnings and Precautions (5.1)] • Serious Infections [see Warnings and Precautions (5.2)] • New Onset Diabetes After Transplant [see Warnings and Precautions (5.4)] • Nephrotoxicity [see Warnings and Precautions (5.5)] • Neurotoxicity [see Warnings and Precautions (5.6)] • Hyperkalemia [see Warnings and Precautions (5.7)] • Hypertension [see Warnings and Precautions (5.8)] • Anaphylactic Reactions with Tacrolimus Injection [see Warnings and Precautions (5.9)] • Myocardial Hypertrophy [see Warnings and Precautions (5.13)] • Pure Red Cell Aplasia [see Warnings and Precautions (5.15)] • Thrombotic Microangiopathy, Including Hemolytic Uremic Syndrome and Thrombotic Thrombocytopenic Purpura [see Warnings and Precautions (5.16)]

6.1Clinical Studies 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 the rates observed in practice. In addition, the clinical trials were not designed to establish comparative differences across study arms with regards to the adverse reactions discussed below. Kidney Transplantation The incidence of adverse reactions was determined in three randomized kidney transplant trials.

One of the trials used azathioprine (AZA) and corticosteroids and two of the trials used mycophenolate mofetil (MMF) and corticosteroids concomitantly for maintenance immunosuppression. Tacrolimus-based immunosuppression in conjunction with azathioprine and corticosteroids following kidney transplantation was assessed in a trial where 205 patients received Tacrolimus-based immunosuppression and 207 patients received cyclosporine-based immunosuppression. The trial population had a mean age of 43 years (mean ± SD was 43 ± 13 years on Tacrolimus and 44 ± 12 years on cyclosporine arm), the distribution was 61% male, and the composition was White (58%), African-American (25%), Hispanic (12%), and Other (5%).

The 12-month post-transplant information from this trial is presented below. The most common adverse reactions (≥ 30%) observed in tacrolimus-treated kidney transplant patients are: infection, tremor, hypertension, abnormal renal function, constipation, diarrhea, headache, abdominal pain, insomnia, nausea, hypomagnesemia, urinary tract infection, hypophosphatemia, peripheral edema, asthenia, pain, hyperlipidemia, hyperkalemia, and anemia. Based on reported adverse reaction terms related to decreased renal function, nephrotoxicity was reported in approximately 52% of kidney transplantation patients.

Adverse reactions that occurred in ≥ 15% of kidney transplant patients treated with tacrolimus in conjunction with azathioprine are presented below: Table 4.

(7.2) • CYP3A Inhibitors: Increased tacrolimus concentrations; monitor concentrations and adjust tacrolimus dose as needed.

(5.11, 7.2) • CYP3A4 Inducers: Decreased tacrolimus concentrations; monitor concentrations and adjust tacrolimus dose as needed. (5.11, 7.2) • Therapeutic drug monitoring and dose reduction for tacrolimus should be considered when tacrolimus is co-administered with cannabidiol (5.17, 7.3).

7.1Mycophenolic Acid When tacrolimus is prescribed with a given dose of a mycophenolic acid (MPA) product, exposure to MPA is higher with tacrolimus co-administration than with cyclosporine co-administration with MPA, because cyclosporine interrupts the enterohepatic recirculation of MPA while tacrolimus does not. Monitor for MPA-associated adverse reactions and reduce the dose of concomitantly administered mycophenolic acid products as needed.

7.2Effects of Other Drugs on Tacrolimus Table 15 displays the effects of other drugs on Tacrolimus Table 15. Effects of Other Drugs/Substances on Tacrolimus 1 1. Tacrolimus dosage adjustment recommendation based on observed effect of co-administered drug on tacrolimus exposures [see Clinical Pharmacology (12.3)], literature reports of altered tacrolimus exposures, or the other drug's known CYP3A inhibitor/inducer status.

2. High dose or double strength grapefruit juice is a strong CYP3A inhibitor; low dose or single strength grapefruit juice is a moderate CYP3A inhibitor. 3.

Strong CYP3A inhibitor/inducer, based on reported effect on exposures to tacrolimus along with supporting in vitro CYP3A inhibitor/inducer data, or based on drug-drug interaction studies with midazolam (sensitive CYP3A probe substrate). Drug/Substance Class or Name Drug Interaction Effect Recommendations Grapefruit or grapefruit juice 2 May increase tacrolimus whole blood trough concentrations and increase the risk of serious adverse reactions (e.g., neurotoxicity, QT prolongation) [see Warnings and Precautions (5.6, 5.11, 5.12)].

Avoid grapefruit or grapefruit juice. Strong CYP3A Inducers 3 : Antimycobacterials (e.g., rifampin, rifabutin), anticonvulsants (e.g., phenytoin, carbamazepine and phenobarbital), St John's wort May decrease tacrolimus whole blood trough concentrations and increase the risk of rejection [see Warnings and Precautions (5.11)] . Increase tacrolimus dose and monitor tacrolimus whole blood trough concentrations [see Dosage and Administration (2.2, 2.6) and Clinical Pharmacology (12.3)] .

Strong CYP3A Inhibitors 3 : Protease inhibitors (e.g, nelfinavir, telaprevir, boceprevir, ritonavir), azole antifungals (e.g., voriconazole, posaconazole, itraconazole, ketoconazole), antibiotics (e.g., clarithromycin, troleandomycin, chloramphenicol), nefazodone, letermovir, Schisandra sphenanthera extracts May increase tacrolimus whole blood trough concentrations and increase the risk of serious adverse reactions (e.g., neurotoxicity, QT prolongation). A rapid, sharp rise in tacrolimus levels may occur early, despite an immediate reduction of tacrolimus dose [see Warnings and Precautions (5.6, 5.11, 5.12)].

Reduce tacrolimus dose (for voriconazole and posaconazole, give one-third of the original dose) and adjust dose based on tacrolimus whole blood trough concentrations [see Dosage and Administration (2.2, 2.6) and Clinical Pharmacology (12.3)] . Early and frequent monitoring of tacrolimus whole blood trough levels should start within 1-3 days and continue monitoring as necessary [see Warnings and Precautions (5.11)]. Mild or Moderate CYP3A Inhibitors: Clotrimazole, antibiotics (e.g., erythromycin, fluconazole), calcium channel blockers (e.g., verapamil, diltiazem, nifedipine, ni… [Excerpted — this section continues on DailyMed.]

8 USE IN SPECIFIC POPULATIONS Pregnancy: Can cause fetal harm. Advise pregnant women of the potential risk to the fetus. (8.1, 8.3) Additional pediatric use information is approved for Astellas Pharma US, Inc.'s Prograf (tacrolimus) products. However, due to Astellas Pharma US, Inc.'s marketing exclusivity rights, this drug product is not labeled with that information.

8.1Pregnancy Risk Summary Tacrolimus can cause fetal harm when administered to a pregnant woman. Data from postmarketing surveillance and TPRI suggest that infants exposed to tacrolimus in utero are at a risk of prematurity, birth defects/congenital anomalies, low birth weight, and fetal distress [see Human Data]. Advise pregnant women of the potential risk to the fetus.

Administration of oral tacrolimus to pregnant rabbits and rats throughout the period of organogenesis was associated with maternal toxicity/lethality, and an increased incidence of abortion, malformation and embryofetal death at clinically relevant doses (0.5 to 6.9 times the recommended clinical dose range [0.2 to 0.075 mg/kg/day], on a mg/m 2 basis). Administration of oral tacrolimus to pregnant rats after organogenesis and throughout lactation produced maternal toxicity, effects on parturition, reduced pup viability and reduced pup weight at clinically relevant doses (0.8 to 6.9 times the recommended clinical dose range, on a mg/m 2 basis).

Administration of oral tacrolimus to rats prior to mating, and throughout gestation and lactation produced maternal toxicity/lethality, marked effects on parturition, embryofetal loss, malformations, and reduced pup viability at clinically relevant doses (0.8 to 6.9 times the recommended clinical dose range, on a mg/m 2 basis). Interventricular septal defects, hydronephrosis, craniofacial malformations and skeletal effects were observed in offspring that died [see Animal Data]. The background risk of major birth defects and miscarriage in the indicated population is unknown.

In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2 to 4% and 15 to 20%, respectively. Clinical Considerations Disease-Associated Maternal and/or Embryo-Fetal Risk Risks during pregnancy are increased in organ transplant recipients. The risk of premature delivery following transplantation is increased.

Pre-existing hypertension and diabetes confer additional risk to the pregnancy of an organ transplant recipient. Pre-gestational and gestational diabetes are associated with birth defects/congenital anomalies, hypertension, low birth weight and fetal death. Cholestasis of pregnancy (COP) was reported in 7% of liver or liver-kidney (LK) transplant recipients, compared with approximately 1% of pregnancies in the general population.

However, COP symptoms resolved postpartum and no long-term effects on the offspring were reported. Maternal Adverse Reactions Tacrolimus may increase hyperglycemia in pregnant women with diabetes (including gestational diabetes). Monitor maternal blood glucose levels regularly [see Warnings and Precautions (5.4)].

Tacrolimus may exacerbate hypertension in pregnant women and increase pre-eclampsia. Monitor and control blood pressure [see Warnings and Precautions (5.7, 5.8)]. Fetal/Neonatal Adverse Reactions Renal dysfunction, transient neonatal hyperkalemia and low birth weight have been reported at the time of delivery in infants of mothers taking tacrolimus.

Labor or Delivery There is an increased risk for premature delivery (< 37 weeks) following transplantation and maternal exposure to tacrolimus. Data Human Data There are no adequate and well controlled studies on the effects of tacrolimus in human pregnancy. Safety data from the TPRI and postmarketing surveillance suggest infants exposed to tacrolimus in utero have an increased risk for miscarriage, pre-term delivery (< 37 weeks), low birth weight (< 2500 g), birth defects/congenital anomalies and fetal distress.

🧒 Pediatric Use 163 words ▾

8.4Pediatric Use Safety and effectiveness have been established in pediatric liver transplant patients. Liver Transplantation Safety and efficacy in pediatric liver transplant patients less than 16 years of age are based on evidence from active controlled studies that included 56 pediatric patients, 31 of which received tacrolimus, and supported by two pharmacokinetic and safety studies in 151 children who received tacrolimus. Additionally, 122 pediatric patients were studied in an uncontrolled trial of tacrolimus in living related donor liver transplantation.

Dose adjustments were made in the PK studies based on clinical status and whole blood concentrations. Pediatric patients generally required higher doses of tacrolimus to maintain blood trough concentrations of tacrolimus similar to adult patients [see Dosage and Administration (2.3), Adverse Reactions (6.1), Clinical Pharmacology (12.3) and Clinical Studies (14.2)]. Additional pediatric use information is approved for Astellas Pharma US, Inc.'s Prograf (tacrolimus) products.

🧓 Geriatric Use 83 words ▾

8.5Geriatric Use Clinical trials of tacrolimus did not include sufficient numbers of subjects aged 65 and over to determine whether they respond differently from younger subjects. Other reported clinical experience has not identified differences in responses between the elderly and younger patients. 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.

🆘 Overdosage 148 words ▾

10 OVERDOSAGE Limited overdosage experience is available. Acute overdosages of up to 30 times the intended dose have been reported. Almost all cases have been asymptomatic and all patients recovered with no sequelae.

Acute overdosage was sometimes followed by adverse reactions consistent with those reported with the use of tacrolimus [see Adverse Reactions (6.1, 6.2)], including tremors, abnormal renal function, hypertension, and peripheral edema; in one case of acute overdosage, transient urticaria and lethargy were observed. Based on the poor aqueous solubility and extensive erythrocyte and plasma protein binding, it is anticipated that tacrolimus is not dialyzable to any significant extent; there is no experience with charcoal hemoperfusion.

The oral use of activated charcoal has been reported in treating acute overdoses, but experience has not been sufficient to warrant recommending its use. General supportive measures and treatment of specific symptoms should be followed in all cases of overdosage.

12 CLINICAL PHARMACOLOGY

12.1Mechanism of Action Tacrolimus binds to an intracellular protein, FKBP-12. A complex of tacrolimus-FKBP-12, calcium, calmodulin, and calcineurin (a ubiquitous mammalian intracellular enzyme) is then formed, after which the phosphatase activity of calcineurin is inhibited. Such inhibition prevents the dephosphorylation and translocation of various factors such as the nuclear factor of activated T-cells (NF-AT), and nuclear factor kappa-light-chain enhancer of activated B-cells (NF-κB).

Tacrolimus inhibits the expression and/or production of several cytokines that include interleukin (IL)-1 beta, IL-2, IL-3, IL-4, IL-5, IL-6, IL-8, IL-10, gamma interferon, tumor necrosis factor-alpha, and granulocyte macrophage colony-stimulating factor. Tacrolimus also inhibits IL-2 receptor expression and nitric oxide release, induces apoptosis and production of transforming growth factor beta that can lead to immunosuppressive activity. The net result is the inhibition of T-lymphocyte activation and proliferation, as well as T-helper-cell-dependent B-cell response (i.e., immunosuppression).

12.3Pharmacokinetics Tacrolimus activity is primarily due to the parent drug. The pharmacokinetic parameters (mean ± S.D.) of tacrolimus have been determined following intravenous (IV) and/or oral (PO) administration in healthy volunteers, and in kidney transplant, liver transplant, and heart transplant patients (Table 17).

Pharmacokinetic data indicate that whole blood concentrations rather than plasma concentrations serve as the more appropriate sampling compartment to describe tacrolimus pharmacokinetics. Absorption Absorption of tacrolimus from the gastrointestinal tract after oral administration is incomplete and variable. The absolute bioavailability of tacrolimus was 17 ± 10% in adult kidney transplant patients (N = 26), 22 ± 6% in adult liver transplant patients (N = 17), 23 ± 9% in adult heart transplant patients (N = 11) and 18 ± 5% in healthy volunteers (N = 16).

A single dose trial conducted in 32 healthy volunteers established the bioequivalence of the 1 mg and 5 mg capsules.

💬 Information for Patients ~3 min read ▾

17 PATIENT COUNSELING INFORMATION Advise the patient to read the FDA-approved patient labeling (Patient Information).

17.1Administration Advise the patient or caregiver to: • Inspect their tacrolimus medicine when they receive a new prescription and before taking it. If the appearance of the capsule is not the same as usual, or if dosage instructions have changed, advise patients to contact their healthcare provider as soon as possible to make sure that they have the right medicine. Other tacrolimus products cannot be substituted for tacrolimus. • Take tacrolimus at the same 12-hour intervals every day to achieve consistent blood concentrations. • Take tacrolimus consistently either with or without food because the presence and composition of food decreases the bioavailability of tacrolimus. • Not to eat grapefruit or drink grapefruit juice in combination with tacrolimus [see Drug Interactions (7.2)].

17.2Development of Lymphoma and Other Malignancies Inform patients they are at increased risk of developing lymphomas and other malignancies, particularly of the skin, due to immunosuppression. Advise patients to limit exposure to sunlight and ultraviolet (UV) light by wearing protective clothing and using a broad spectrum sunscreen with a high protection factor [see Warnings and Precautions (5.1)].

17.3Increased Risk of Infection Inform patients they are at increased risk of developing a variety of infections, including opportunistic infections, due to immunosuppression and to contact their physician if they develop any symptoms of infection such as fever, sweats or chills, cough or flu-like symptoms, muscle aches, or warm, red, painful areas on the skin [see Warnings and Precautions (5.2)].

17.4New Onset Diabetes After Transplant Inform patients that tacrolimus can cause diabetes mellitus and should be advised to contact their physician if they develop frequent urination, increased thirst, or hunger [see Warnings and Precautions (5.4)] .

17.5Nephrotoxicity Inform patients that tacrolimus can have toxic effects on the kidney that should be monitored. Advise patients to attend all visits and complete all blood tests ordered by their medical team [see Warnings and Precautions (5.5)] .

17.6Neurotoxicity Inform patients that they are at risk of developing adverse neurologic reactions including seizure, altered mental status, and tremor. Advise patients to contact their physician should they develop vision changes, delirium, or tremors [see Warnings and Precautions (5.6)] .

17.7Hyperkalemia Inform patients that tacrolimus can cause hyperkalemia. Monitoring of potassium levels may be necessary, especially with concomitant use of other drugs known to cause hyperkalemia [see Warnings and Precautions (5.7)] .

17.8Hypertension Inform patients that tacrolimus can cause high blood pressure which may require treatment with antihypertensive therapy. Advise patients to monitor their blood pressure [see Warnings and Precautions (5.8)] .

17.9Thrombotic Microangiopathy Inform patients that tacrolimus can cause blood clotting problems. The risk of this occurring increases when patients take tacrolimus and sirolimus or everolimus concomitantly, or when patients develop certain infections. Advise them to seek medical attention promptly if they develop fever, petequiae or bruises, fatigue, confusion, jaundice, oliguria. [see Warnings and Precautions (5.16)]

17.10Drug Interactions Instruct patients to tell their healthcare providers when they start or stop taking any medicines, including prescription medicines and nonprescription medicines, natural or herbal remedies, nutritional supplements, and vitamins. Advise patients to avoid grapefruit and grapefruit juice [see Drug Interactions (7)].

If pediatric patients are converted between formulations, therapeutic drug monitoring must be performed and dose adjustments made to ensure that systemic exposure to tacrolimus is maintained. Food Effects The rate and extent of tacrolimus absorption were greatest under fasted conditions. The presence and composition of food decreased both the rate and extent of tacrolimus absorption when administered to 15 healthy volunteers.

The effect was most pronounced with a high-fat meal (848 kcal, 46% fat): mean AUC and C max were decreased 37% and 77%, respectively; T max was lengthened 5-fold. A high-carbohydrate meal (668 kcal, 85% carbohydrate) decreased mean AUC and mean C max by 28% and 65%, respectively. In healthy volunteers (N = 16), the time of the meal also affected tacrolimus bioavailability.

When given immediately following the meal, mean C max was reduc… [Excerpted — this section continues on DailyMed.]

14 CLINICAL STUDIES

14.1Kidney Transplantation Tacrolimus/Azathioprine (AZA) Tacrolimus-based immunosuppression in conjunction with azathioprine and corticosteroids following kidney transplantation was assessed in a randomized, multicenter, non-blinded, prospective trial. There were 412 kidney transplant patients enrolled at 19 clinical sites in the United States. Study therapy was initiated when renal function was stable as indicated by a serum creatinine ≤ 4 mg/dL (median of 4 days after transplantation, range 1 to 14 days).

Patients less than 6 years of age were excluded. There were 205 patients randomized to tacrolimus-based immunosuppression and 207 patients were randomized to cyclosporine-based immunosuppression. All patients received prophylactic induction therapy consisting of an antilymphocyte antibody preparation, corticosteroids, and azathioprine.

Overall, 1-year patient and graft survivals were 96.1% and 89.6%, respectively. Data from this trial of tacrolimus in conjunction with azathioprine indicate that during the first 3 months of that trial, 80% of the patients maintained trough concentrations between 7-20 ng/mL, and then between 5-15 ng/mL, through 1 year. Tacrolimus/Mycophenolate Mofetil (MMF) Tacrolimus-based immunosuppression in conjunction with MMF, corticosteroids, and induction has been studied.

In a randomized, open-label, multicenter trial (Study 1), 1589 kidney transplant patients received tacrolimus (Group C, n = 401), sirolimus (Group D, n = 399), or one of two cyclosporine (CsA) regimens (Group A, n = 390 and Group B, n = 399) in combination with MMF and corticosteroids; all patients, except those in one of the two cyclosporine groups, also received induction with daclizumab. The trial was conducted outside the United States; the trial population was 93% Caucasian. In this trial, mortality at 12 months in patients receiving tacrolimus/MMF was similar (3%) compared to patients receiving cyclosporine/MMF (3% and 2%) or sirolimus/MMF (3%).

Patients in the tacrolimus group exhibited higher estimated creatinine clearance rates (eCL cr ) using the Cockcroft-Gault formula (Table 20) and experienced fewer efficacy failures, defined as biopsy-proven acute rejection (BPAR), graft loss, death, and/or loss to follow-up (Table 21) in comparison to each of the other three groups. Patients randomized to tacrolimus/MMF were more likely to develop diarrhea and diabetes after the transplantation and experienced similar rates of infections compared to patients randomized to either cyclosporine/MMF regimen [see Adverse Reactions (6.1)].

Table 20. Estimated Creatinine Clearance at 12 Months (Study 1) 1. All death/graft loss (n = 41, 27, 23, and 42 in Groups A, B, C, and D) and patients whose last recorded creatinine values were prior to month 3 visit (n = 10, 9, 7, and 9 in Groups A, B, C, and D, respectively) were imputed with Glomerular Filtration Rate (GFR) of 10 mL/min; a subject's last observed creatinine value from month 3 on was used for the remainder of subjects with missing creatinine at month 12 (n = 11, 12, 15, and 19 for Groups A, B, C, and D, respectively).Weight was also imputed in the calculation of estimated GFR, if missing.

13 NONCLINICAL TOXICOLOGY

13.1Carcinogenesis, Mutagenesis, Impairment of Fertility Carcinogenesis Carcinogenicity studies were conducted in male and female rats and mice. In the 80-week mouse oral study and in the 104-week rat oral study, no relationship of tumor incidence to tacrolimus dosage was found. The highest dose used in the mouse was 3.0 mg/kg/day (0.9 to 2.2 times the AUC at clinical doses of 0.075 to 0.2 mg/kg/day) and in the rat was 5.0 mg/kg/day (0.265 to 0.65 times the AUC at clinical doses of 0.075 to 0.2 mg/kg/day) [see Warnings and Precautions (5.1)].

A 104-week dermal carcinogenicity study was performed in mice with tacrolimus ointment (0.03% - 3%), equivalent to tacrolimus doses of 1.1-118 mg/kg/day or 3.3-354 mg/m 2 /day. In the study, the incidence of skin tumors was minimal and the topical application of tacrolimus was not associated with skin tumor formation under ambient room lighting. However, a statistically significant elevation in the incidence of pleomorphic lymphoma in high-dose male (25/50) and female animals (27/50) and in the incidence of undifferentiated lymphoma in high-dose female animals (13/50) was noted in the mouse dermal carcinogenicity study.

Lymphomas were noted in the mouse dermal carcinogenicity study at a daily dose of 3.5 mg/kg (0.1% tacrolimus ointment). No drug-related tumors were noted in the mouse dermal carcinogenicity study at a daily dose of 1.1 mg/kg (0.03% tacrolimus ointment). The relevance of topical administration of tacrolimus in the setting of systemic tacrolimus use is unknown.

The implications of these carcinogenicity studies to the human condition are limited; doses of tacrolimus were administered that likely induced immunosuppression in these animals, impairing their immune system's ability to inhibit unrelated carcinogenesis. Mutagenesis No evidence of genotoxicity was seen in bacterial (Salmonella and E. coli) or mammalian (Chinese hamster lung-derived cells) in vitro assays of mutagenicity, the in vitro CHO/HGPRT assay of mutagenicity, or in vivo clastogenicity assays performed in mice; tacrolimus did not cause unscheduled DNA synthesis in rodent hepatocytes.

Impairment of Fertility Tacrolimus, subcutaneously administered to male rats at paternally toxic doses of 2 mg/kg/day (1.6 to 4.3 times the recommended clinical dose range [0.2 to 0.075 mg/kg/day] on a mg/m 2 basis) or 3 mg/kg/day (2.4 to 6.4 times the recommended clinical dose range), resulted in a dose-related decrease in sperm count. Tacrolimus, administered orally at 1.0 mg/kg (0.8 to 2.2 times the clinical dose range) to male and female rats, prior to and during mating, as well as to dams during gestation and lactation, was associated with embryolethality and adverse effects on female reproduction.

Effects on female reproductive function (parturition) and embryolethal effects were indicated by a higher rate of pre- and post-implantation loss and increased numbers of undelivered and nonviable pups. When administered at 3.2 mg/kg (2.6 to 6.9 times the clinical dose range based on body surface area), tacrolimus was associated with maternal and paternal toxicity as well as reproductive toxicity including marked adverse effects on estrus cycles, parturition, pup viability, and pup malformations.

Medicare Part D spend CMS · PART D · 2026 (Q1)

Medicare Part D (outpatient prescription) spending for Tacrolimus — the program that covers self-administered drugs. 16 manufacturers.
⚠️ Drug-level data: CMS publishes Part D spending by drug, not by NDC — these figures combine every manufacturer, strength and package size sold under the name Tacrolimus. That’s a different level of aggregation than the Medicaid card above, which is specific to this exact 11-digit NDC (pack size included), so the two aren’t directly comparable.

💵 About the dollar figures: spending is what Part D plans paid before confidential manufacturer rebates, so the program’s real net cost is lower. A blank patient count means fewer than 11 people — CMS hides counts that small to protect privacy. Source: CMS Medicare Quarterly Part D Spending by Drug (data.cms.gov), updated quarterly.

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 Cardinal Health 107, LLC. Listing status can change — the directory data on this page refreshes weekly.
Who lists this product with the FDA?
Cardinal Health 107, LLC 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.
Do I need a prescription for this product?
This NDC is listed with FDA as a prescription product, so it is dispensed under a prescriber's order. Your pharmacist can tell you whether any over-the-counter forms of the same medication exist.
This page identifies an FDA-listed package (the NDC) and reports public regulatory and pricing data about the listing. It is reference information, not a medical recommendation — talk to your pharmacist or prescriber about your own medication.
Where does this data come from?
Listing facts (marketing category, packager status, marketing dates) from the FDA openFDA NDC Directory; label availability from DailyMed; pricing coverage from CMS NADAC; equivalence scope from the FDA Orange Book.
