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.

Biologic patent Exclusivity
🏛️Reference-product exclusivity
A flat 12 years of FDA market protection from first licensure. No biosimilar can be licensed before it ends — regardless of patents.
🧪Listed biologic patents
Patents the reference maker lists covering the molecule, formulation, or manufacturing. A biosimilar generally can’t launch until these resolve.
🔁Interchangeability
An interchangeable biosimilar may be substituted at the pharmacy (state laws vary). The first one can earn its own exclusivity period.
🛈 What do these terms mean?
Biologic patent
A patent the reference product’s maker has publicly listed. A biosimilar generally can’t launch until these expire — unless they’re invalidated or resolved in a settlement.
Reference-product exclusivity
A flat 12 years of FDA market protection from the biologic’s first licensure (the BPCIA). No biosimilar can be licensed before it ends, regardless of patents.
Interchangeable exclusivity
The first interchangeable biosimilar can earn a period as the only interchangeable version (pharmacists can substitute it without the prescriber).
Earliest biosimilar (LOE)
The latest of all the dates above — the soonest a biosimilar can realistically reach the market. Litigation and settlements can move it earlier.

Biologics have no small-molecule “generics” — competition comes from FDA-licensed biosimilars, tracked in the FDA Purple Book.

RefProductReference-product exclusivity (12-year, BPCIA) — no biosimilar can be licensed before this dateMay 28, 2036
Common questions
Is there a biosimilar for BKEMV 300 MG/30 ML VIAL?
Yes — at least one FDA-licensed biosimilar is listed for this biologic. See the Purple Book family above for the available products.
Why do different websites show different biosimilar dates?
Biosimilar availability isn’t based on one single date. Some sources use the reference-product exclusivity, some use the last listed patent, and patent litigation, settlements, and licenses can all change the real-world launch date. This page shows the underlying Purple Book dates so you can see why estimates differ.
Can a biosimilar launch before the last patent expires?
Sometimes. A biosimilar maker may settle with the reference manufacturer or receive a license to launch earlier. In other cases, the last listed protection delays competition.
What does “current Purple Book estimate” mean?
It means we’re using the latest patent and exclusivity dates currently listed in the FDA Purple Book. It is not a guaranteed launch date.
What does “FDA listed” mean?
It means the product appears in the FDA’s official directory. That’s a good sign a product exists for the U.S. market, but on its own it does not confirm a pharmacy can get it today. Where we have recent retail pricing data, we label it “Availability likely” instead.
What does a patent or protection date mean here?
It’s the latest date currently listed in the FDA Purple Book for a patent or exclusivity on the reference biologic. It can affect when a biosimilar becomes widely available — but it is not a guaranteed launch date. Settlements and licenses can move the real date earlier or later.
Built from the FDA Purple Book Patent List (patents the reference-product sponsor has publicly listed under the BPCIA) plus reference-product exclusivity. Biosimilars cannot launch until these clear; patent litigation and settlements can shift the real date. Biologics have no small-molecule generics — competition comes from FDA-licensed biosimilars, not the Orange Book.
Where does this data come from?
Patents and exclusivity from the FDA Purple Book (biologics), refreshed from public FDA data. Biosimilar launch timing is an estimate, not a guarantee.

⚠️ Warnings and Cautions ~3 min read ▾

5 WARNINGS AND PRECAUTIONS Use caution when administering BKEMV to patients with any other systemic infection. ( 5.3 ) Infusion-Related Reactions: Monitor patients during infusion, interrupt for reactions, and institute appropriate supportive measures. ( 5.6 )

5.1Serious Meningococcal Infections Eculizumab products, complement inhibitors, increase a patient's susceptibility to serious, life-threatening, or fatal infections caused by meningococcal bacteria (septicemia and/or meningitis) in any serogroup, including non-groupable strains. Life-threatening and fatal meningococcal infections have occurred in both vaccinated and unvaccinated patients treated with complement inhibitors. The initiation of BKEMV treatment is contraindicated in patients with unresolved serious Neisseria meningitidis infection.

Complete or update meningococcal vaccination (for serogroups A, C, W, Y and B) at least 2 weeks prior to administration of the first dose of BKEMV, according to current ACIP recommendations for patients receiving a complement inhibitor. Revaccinate patients in accordance with ACIP recommendations considering the duration of therapy with BKEMV. Note that ACIP recommends an administration schedule in patients receiving complement inhibitors that differs from the administration schedule in the vaccine prescribing information.

If urgent BKEMV therapy is indicated in a patient who is not up to date with meningococcal vaccines according to ACIP recommendations, provide the patient with antibacterial drug prophylaxis and administer meningococcal vaccines as soon as possible. Various durations and regimens of antibacterial drug prophylaxis have been considered, but the optimal durations and drug regimens for prophylaxis and their efficacy have not been studied in unvaccinated or vaccinated patients receiving complement inhibitors, including eculizumab products.

The benefits and risks of treatment with BKEMV, as well as the benefits and risks of antibacterial drug prophylaxis in unvaccinated or vaccinated patients, must be considered against the known risks for serious infections caused by Neisseria meningitidis . Vaccination does not eliminate the risk of serious meningococcal infections, despite development of antibodies following vaccination. Closely monitor patients for early signs and symptoms of meningococcal infection and evaluate patients immediately if infection is suspected.

Inform patients of these signs and symptoms and instruct patients to seek immediate medical care if these signs and symptoms occur. Promptly treat known infections. Meningococcal infection may become rapidly life-threatening or fatal if not recognized and treated early.

Consider interruption of BKEMV in patients who are undergoing treatment for serious meningococcal infection, depending on the risks of interrupting treatment in the disease being treated. BKEMV is available only through a restricted program under a REMS [see Warnings and Precautions (5.2) ] .

5.2BKEMV REMS BKEMV is available only through a restricted program under a REMS called BKEMV REMS, because of the risk of serious meningococcal infections [see Warnings and Precautions (5.1) ] . Notable requirements of the BKEMV REMS include the following: Prescribers must enroll in the REMS. Prescribers must counsel patients about the risk of serious meningococcal infection.

Prescribers must provide the patients with the REMS educational materials. Prescribers must assess patient vaccination status for meningococcal vaccines (against serogroups A, C, W, Y and B) and vaccinate if needed according to current ACIP recommendations 2 weeks prior to the first dose of BKEMV. Prescribers must provide a prescription for antibacterial drug prophylaxis if treatment must be started urgently and the patient is not up to date with meningococcal vaccines according to current ACIP recommendations at least two weeks prior to the first dose of BKEMV.

Healthcare settings and pharmacies that dispense BKEMV must be certifi… [Excerpted — this section continues on DailyMed.]

6.1Clinical Trial 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. Meningococcal infections are the most important adverse reactions experienced by patients receiving eculizumab. In PNH clinical studies, two patients experienced meningococcal sepsis.

Both patients had previously received a meningococcal vaccine. In clinical studies among patients without PNH, meningococcal meningitis occurred in one unvaccinated patient. Meningococcal sepsis occurred in one previously vaccinated patient enrolled in the retrospective aHUS study during the post-study follow-up period [see Warnings and Precautions (5.1) ] .

PNH The data described below reflect exposure to eculizumab in 196 adult patients with PNH, age 18-85, of whom 55% were female. All had signs or symptoms of intravascular hemolysis. Eculizumab was studied in a placebo-controlled clinical study (PNH Study 1, in which 43 patients received eculizumab and 44, placebo); a single arm clinical study (PNH Study 2); and a long-term extension study (E05-001).

One hundred and eighty two patients were exposed for greater than one year. All patients received the recommended eculizumab dose regimen. Table 5 summarizes the adverse reactions that occurred at a numerically higher rate in the eculizumab group than the placebo group and at a rate of 5% or more among patients treated with eculizumab.

8 USE IN SPECIFIC POPULATIONS

8.1Pregnancy Risk Summary Limited data on outcomes of pregnancies that have occurred following eculizumab use in pregnant women have not identified a concern for specific adverse developmental outcomes ( see Data ). There are risks to the mother and fetus associated with untreated paroxysmal nocturnal hemoglobinuria (PNH) and atypical hemolytic uremic syndrome (aHUS) in pregnancy ( see Clinical Considerations ). Animal studies using a mouse analogue of the eculizumab molecule (murine anti-C5 antibody) showed increased rates of developmental abnormalities and an increased rate of dead and moribund offspring at doses 2-8 times the human dose ( see Data ) .

The estimated background risk of major birth defects and miscarriage for the indicated populations is unknown. All pregnancies have a background risk of birth defect, loss, or other adverse outcomes. In the U.S. general population, the estimated background risk of major birth defect and miscarriage in clinically recognized pregnancies is 2-4% and 15-20%, respectively.

Clinical Considerations Disease-associated maternal and/or fetal/neonatal risk PNH in pregnancy is associated with adverse maternal outcomes, including worsening cytopenias, thrombotic events, infections, bleeding, miscarriages and increased maternal mortality, and adverse fetal outcomes, including fetal death and premature delivery. aHUS in pregnancy is associated with adverse maternal outcomes, including pre-eclampsia and preterm delivery, and adverse fetal/neonatal outcomes, including intrauterine growth restriction (IUGR), fetal death and low birth weight.

Data Human Data A pooled analysis of prospectively (50.3%) and retrospectively (49.7%) collected data in more than 300 pregnant women with live births following exposure to eculizumab have not suggested safety concerns. However, these data cannot definitively exclude any drug-associated risk during pregnancy, because of the limited sample size. Animal Data Animal reproduction studies were conducted in mice using doses of a murine anti-C5 antibody that approximated 2-4 times (low dose) and 4-8 times (high dose) the recommended human eculizumab dose, based on a body weight comparison.

When animal exposure to the antibody occurred in the time period from before mating until early gestation, no decrease in fertility or reproductive performance was observed. When maternal exposure to the antibody occurred during organogenesis, two cases of retinal dysplasia and one case of umbilical hernia were observed among 230 offspring born to mothers exposed to the higher antibody dose; however, the exposure did not increase fetal loss or neonatal death. When maternal exposure to the antibody occurred in the time period from implantation through weaning, a higher number of male offspring became moribund or died (1/25 controls, 2/25 low dose group, 5/25 high dose group).

Surviving offspring had normal development and reproductive function.

8.2Lactation Risk Summary Although limited published data does not report detectable levels of eculizumab in human milk, maternal IgG is known to be present in human milk. Available information is insufficient to inform the effect of eculizumab products on the breastfed infant. There are no data on the effects of eculizumab products on milk production.

The developmental and health benefits of breastfeeding should be considered along with the mother's clinical need for BKEMV and any potential adverse effects on the breastfed child from BKEMV or from the underlying maternal condition.

8.4Pediatric Use PNH and NMOSD Safety and effectiveness of BKEMV for the treatment of PNH or NMOSD in pediatric patients have not been established. aHUS The safety and effectiveness of BKEMV for the treatment of aHUS have been established in pediatric patients.

12 CLINICAL PHARMACOLOGY

12.1Mechanism of Action Eculizumab-aeeb, the active ingredient in BKEMV, is a monoclonal antibody that specifically binds to the complement protein C5 with high affinity, thereby inhibiting its cleavage to C5a and C5b and preventing the generation of the terminal complement complex C5b-9. Eculizumab products inhibit terminal complement-mediated intravascular hemolysis in PNH patients and complement-mediated thrombotic microangiopathy (TMA) in patients with aHUS. The precise mechanism by which eculizumab products exert their therapeutic effect in gMG patients is unknown, but is presumed to involve reduction of terminal complement complex C5b-9 deposition at the neuromuscular junction.

The precise mechanism by which eculizumab products exert their therapeutic effect in NMOSD is unknown, but is presumed to involve inhibition of aquaporin-4-antibody induced terminal complement C5b-9 deposition.

12.2Pharmacodynamics In the placebo-controlled clinical study (PNH Study 1), eculizumab when administered as recommended reduced serum LDH levels from 2200 ± 1034 U/L (mean ± SD) at baseline to 700 ± 388 U/L by week one and maintained the effect through the end of the study at week 26 (327 ± 433 U/L) in patients with PNH. In the single arm clinical study (PNH Study 2), the effect was maintained through week 52 [see Clinical Studies (14) ] . In patients with PNH, aHUS, gMG, and NMOSD, free C5 concentrations of < 0.5 mcg/mL was correlated with complete blockade of terminal complement activity.

12.3Pharmacokinetics Following intravenous maintenance doses of 900 mg once every 2 weeks in patients with PNH, the week 26 observed mean ± SD serum eculizumab maximum concentration (C max ) was 194 ± 76 mcg/mL and the trough concentration (C trough ) was 97 ± 60 mcg/mL. Following intravenous maintenance doses of 1200 mg once every 2 weeks in patients with aHUS, the week 26 observed mean ± SD C trough was 242 ± 101 mcg/mL. Following intravenous maintenance doses of 1200 mg once every 2 weeks in adult patients with gMG, the week 26 observed mean ± SD C max was 783 ± 288 mcg/mL and the C trough was 341 ± 172 mcg/mL.

Following intravenous maintenance doses of 1200 mg once every 2 weeks in patients with NMOSD, at week 24, the observed mean ± SD C max was 877 ± 331 and the C trough was 429 ± 188 mcg/mL. Steady state was achieved 4 weeks after starting eculizumab treatment, with accumulation ratio of approximately 2-fold in all studied indications. Population pharmacokinetic analyses showed that eculizumab pharmacokinetics were dose-linear and time-independent over the 600 mg to 1200 mg dose range, with inter-individual variability of 21% to 38%.

Distribution The eculizumab volume of distribution for a typical 70 kg patient was 5 L to 8 L. Elimination The half-life of eculizumab ranged between 141 hours and 882 hours. Plasma exchange or infusion increased the clearance of eculizumab by approximately 6.01-fold and reduced the half-life to 90.2 hours.

Supplemental dosing is recommended when BKEMV is administered to patients receiving plasma exchange or infusion [see Dosage and Administration (2.5) ] . Specific Populations Age, Sex, and Race: The pharmacokinetics of eculizumab were not affected by age (2 months to 85 years), sex, or race. Renal Impairment: Renal function did not affect the pharmacokinetics of eculizumab in PNH (creatinine clearance of 8 mL/min to 396 mL/min calculated using Cockcroft-Gault formula), aHUS (estimated glomerular filtration rate [eGFR] of 5 mL/min/1.73 m 2 to 105 mL/min/1.73 m 2 using the Modification of Diet in Renal Disease [MDRD] formula), or gMG patients (eGFR of 44 mL/min/1.73 m 2 to 168 mL/min/1.73 m 2 using MDRD formula).

💬 Information for Patients ~2 min read ▾

17 PATIENT COUNSELING INFORMATION Advise the patients and/or caregivers to read the FDA-approved patient labeling (Medication Guide). Serious Meningococcal Infections Advise patients of the risk of serious meningococcal infection. Inform patients of the need to complete or update their meningococcal vaccinations at least 2 weeks prior to receiving the first dose of BKEMV or receive antibacterial drug prophylaxis if BKEMV treatment must be initiated immediately and they have not been previously vaccinated.

Inform patients of the requirement to be revaccinated according to current ACIP recommendations for meningococcal infection while on BKEMV therapy [see Warnings and Precautions (5.1) ] . Inform patients that vaccination may not prevent serious meningococcal infection and to seek immediate medical attention if the following signs or symptoms occur [see Warnings and Precautions (5.1) ] : fever fever and a rash fever with high heart rate headache with nausea or vomiting headache and a fever headache with a stiff neck or stiff back confusion muscle aches with flu-like symptoms eyes sensitive to light Inform patients that they will be given a Patient Safety Card for BKEMV that they should carry with them at all times during and for 3 months following treatment with BKEMV.

This card describes symptoms which, if experienced, should prompt the patient to immediately seek medical evaluation. BKEMV REMS BKEMV is available only through a restricted program called BKEMV REMS [see Warnings and Precautions (5.2) ] . Inform the patient of the following notable requirements: Patients must receive counseling about the risk of serious meningococcal infections.

Patients must receive written educational materials about this risk. Patients must be instructed to carry the Patient Safety Card with them at all times during and for 3 months following treatment with BKEMV. Patients must be instructed to complete or update meningococcal vaccines for serogroups A, C, W, Y and B per ACIP recommendations as directed by the prescriber prior to treatment with BKEMV.

Patients must receive antibiotics as directed by the prescriber if they are not up to date with meningococcal vaccines and have to start BKEMV right away. Other Infections Counsel patients about gonorrhea prevention and advise regular testing for patients at-risk. Inform patients that there may be an increased risk of other types of infections, particularly those due to encapsulated bacteria.

Aspergillus infections have occurred in immunocompromised and neutropenic patients. Inform parents or caregivers of children receiving BKEMV for the treatment of aHUS that their child should be vaccinated against Streptococcus pneumoniae and Haemophilus influenzae type b (Hib) according to current medical guidelines. Infusion-Related Reactions Advise patients that administration of BKEMV may result in infusion-related reactions.

Discontinuation Inform patients with PNH that they may develop serious hemolysis due to PNH when BKEMV is discontinued and that they will be monitored by their healthcare professional for at least 8 weeks following BKEMV discontinuation. Inform patients with aHUS that there is a potential for TMA complications due to aHUS when BKEMV is discontinued and that they will be monitored by their healthcare professional for at least 12 weeks following BKEMV discontinuation. Inform patients who discontinue BKEMV to keep the Patient Safety Card with them for three months after the last BKEMV dose, because the increased risk of meningococcal infection persists for several weeks following discontinuation of BKEMV.

This Medication Guide has been approved by the U.S. Food and Drug Administration. Revised 06/2026 MEDICATION GUIDE BKEMV ® (bee-KEM-vee) (eculizumab-aeeb) injection, for intravenous use What is the most important information I should know about BKEMV?

BKEMV is a medicine that affects your immune system. BKEMV may lower the ability of your immune system to fight infections. BKEMV increases your chance of getting serious meningococcal infections caused by Neisseria meningitidis bacteria.

Meningococcal infections may quickly become life-threatening or cause death if not recognized and treated early. You must complete or update your meningococcal vaccine(s) at least 2 weeks before your first dose of BKEMV. If you have not completed your meningococcal vaccines and BKEMV must be started right away, you should receive the required vaccine(s) as soon as possible.

If you have not been vaccinated and BKEMV must be started right away, you should also receive antibiotics to take for as long as your healthcare provider tells you. If you had a meningococcal vaccine in the past, you might need additional vaccines before starting BKEMV. Your healthcare provider will decide if you need additional meningococcal vaccines.

Meningococcal vaccines do not prevent all meningococcal infections. Call your healthcare provider or get emergency medical care right away if you get any of these signs and symptoms of a serious meningococcal infection: fever fever with high heart rate headache and fever confusion muscle aches with flu-like symptoms fever and a rash headache with nausea or vomiting headache with a stiff neck or stiff back eyes sensitive to light Your healthcare provider will give you a Patient Safety Card about the risk of serious meningococcal infection.

Carry it with you at all times during treatment and for 3 months after your last dose of BKEMV. Your risk of meningococcal infection may continue for several weeks after your last dose of BKEMV. It is important to show this card to any healthcare provider who treats you.

This will help them diagnose and treat you quickly. BKEMV is only available through a program called the BKEMV Risk Evaluation and Mitigation Strategy (REMS). Before you can receive BKEMV, your healthcare provider must: enroll in the BKEMV REMS program. counsel you about the risk of serious meningococcal infections. give you information about the signs and symptoms of serious meningococcal infection. make sure that you are vaccinated against serious infections caused by meningococcal bacteria and that you receive antibiotics if you need to start BKEMV right away and you are not up to date on your vaccines. give you a Patient Safety Card about your risk of meningococcal infection, as discussed above.

BKEMV may also increase the risk of other types of serious infections caused by encapsulated bacteria, including Streptococcus pneumoniae , Haemophilus influenzae , and Neisseria gonorrhoeae . If your child is treated with BKEMV, your child should receive vaccines against Streptococcus pneumoniae and Haemophilus influenzae type b (Hib). Certain people may be at risk of serious infections with gonorrhea.

Talk to your healthcare provider about whether you are at risk for gonorrhea infection, about gonorrhea prevention, and regular testing. Certain fungal infections (aspergillus) may also happen if you take BKEMV and have a weak immune system or a low white blood cell count. For more information about side effects, see " What are the possible side effects of BKEMV? " What is BKEMV?

BKEMV is a prescription medicine used to treat: people with paroxysmal nocturnal hemoglobinuria (PNH). people with atypical hemolytic uremic syndrome (aHUS).

14 CLINICAL STUDIES

14.1Paroxysmal Nocturnal Hemoglobinuria (PNH) The safety and efficacy of eculizumab in PNH patients with hemolysis were assessed in a randomized, double-blind, placebo-controlled 26-week study (PNH Study 1, NCT00122330); PNH patients were also treated with eculizumab in a single arm 52-week study (PNH Study 2, NCT00122304) and in a long-term extension study (E05-001, NCT00122317). Patients received meningococcal vaccination prior to receipt of eculizumab. In all studies, the dose of eculizumab was 600 mg study drug every 7 ± 2 days for 4 weeks, followed by 900 mg 7 ± 2 days later, then 900 mg every 14 ± 2 days for the study duration.

Eculizumab was administered as an intravenous infusion over 25 - 45 minutes. PNH Study 1: PNH patients with at least four transfusions in the prior 12 months, flow cytometric confirmation of at least 10% PNH cells and platelet counts of at least 100,000/microliter were randomized to either eculizumab (n = 43) or placebo (n = 44). Prior to randomization, all patients underwent an initial observation period to confirm the need for RBC transfusion and to identify the hemoglobin concentration (the "set-point") which would define each patient's hemoglobin stabilization and transfusion outcomes.

The hemoglobin set-point was less than or equal to 9 g/dL in patients with symptoms and was less than or equal to 7 g/dL in patients without symptoms. Endpoints related to hemolysis included the numbers of patients achieving hemoglobin stabilization, the number of RBC units transfused, fatigue, and health-related quality of life. To achieve a designation of hemoglobin stabilization, a patient had to maintain a hemoglobin concentration above the hemoglobin set-point and avoid any RBC transfusion for the entire 26-week period.

Hemolysis was monitored mainly by the measurement of serum LDH levels, and the proportion of PNH RBCs was monitored by flow cytometry. Patients receiving anticoagulants and systemic corticosteroids at baseline continued these medications. Major baseline characteristics were balanced (see Table 11 ).

These effects were seen among patients within each of the three pre-study RBC transfusion strata (4 - 14 units; 15 - 25 units; >25 units). After 3 weeks of eculizumab treatment, patients reported less fatigue and improved health-related quality of life. Because of the study sample size and duration, the effects of eculizumab products on thrombotic events could not be determined.

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 Amgen Inc. Listing status can change — the directory data on this page refreshes weekly.
Who lists this product with the FDA?
Amgen Inc 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.
Does this product have a billing J-code?
Yes — this NDC cross-references HCPCS code Q5152 for medical-claim billing (typically used when a product is administered in a clinical setting rather than dispensed at a retail pharmacy). See the Billing section on this page.
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.
For educational and professional reference only — not medical advice. Pricing reflects published NADAC and CMS ASP (free public data) and may differ from your acquisition cost; always verify before billing or dispensing.
