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.

Price systemPer mLPer package
Retail pharmacies payNADAC · weekly Not in the retail survey — common for institutional, discontinued, or low-volume packs.
Medicaid paysCMS SDUD · 12 mo No recent Medicaid claims on file for this NDC — rare and low-volume NDCs are suppressed in the public data.
Medicare drug plans payPart D · quarterly No Part D plan price is available for this NDC in our data.
ℹ️
No price is published for this exact package yet. CMS surveys NADAC per package size, so a different pack of the same drug often has one.
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.

LOE
Substance patent Formulation patent Method-of-use patent Exclusivity Pediatric +6mo
🏛️FDA exclusivity
FDA-granted marketing protection. It’s separate from patents and may be shorter than patent protection.
🧪Product / substance patents
Patents covering the active ingredient, product, formulation, or related drug features.
🎯Method-of-use patents
Patents covering specific approved uses. These can sometimes be carved out with a “skinny label,” but not always.
🛈 What do these terms mean?
Patent
Legal protection listed in the Orange Book that may delay generic approval or launch. Issued by the U.S. Patent & Trademark Office.
Substance patent
Covers the active drug molecule itself — the hardest to design around. A generic generally can’t launch until it expires.
Formulation (product) patent
Covers a specific formulation or dosage form. A generic can sometimes work around it with a different formulation.
Method-of-use patent
A patent covering one specific approved use of the drug — not necessarily the whole molecule. A generic can sometimes launch with a “skinny label” that carves out the protected use and keeps the others.
Skinny label
A generic label that omits a still-patented use when the FDA allows it — letting a generic reach the market for the unprotected uses.
Exclusivity
FDA-granted marketing protection, separate from patents — e.g. 5-yr new chemical entity, 7-yr orphan drug, or a +6-month pediatric extension.
Paragraph IV
A generic applicant’s formal challenge to a listed patent. It can potentially lead to earlier generic entry, but often involves litigation or a settlement.
RLD / RS
Reference Listed Drug — the brand product the FDA uses as the reference for generic applications. Reference Standard — the product the FDA expects generics to compare against in bioequivalence testing.
TE / AB rating
FDA therapeutic-equivalence rating. An AB rating generally means the FDA considers a generic therapeutically equivalent to — and substitutable for — the brand.
LOE (loss of exclusivity)
The latest patent or exclusivity currently listed — the loss-of-exclusivity / latest-listed-protection date shown on this page. Paragraph-IV challenges and settlements can move the real date earlier; FDA approval and a manufacturer’s decision to market can move it later.

Built from the FDA Orange Book. The bars above are scaled to each protection’s expiry; the red LOE marker is the last one to lapse.

Common questions
Is there a generic version of AURLUMYN 100 MCG/ML VIAL?
No FDA-approved generic equivalent is currently listed in the FDA Orange Book for AURLUMYN 100 MCG/ML VIAL. Based on the patents and exclusivity currently listed, the Orange Book estimate is that full-label generic entry may be delayed until Jul 2044 — an estimate, not a guaranteed launch date.
The FDA approved a generic — why can’t I get it at my pharmacy yet?
FDA approval and pharmacy availability are two different things. The FDA can approve a generic years before it actually reaches pharmacies, because the brand company may still hold patents or have a settlement that delays the launch. A manufacturer also has to choose to make and sell it, and have supply ready. So a drug can be “FDA-approved generic exists” and still be brand-only at the counter today.
Why do different websites show different generic release dates?
Generic availability is not based on one single date. Some sources use the first exclusivity expiration, some use the last product patent, and others use the latest method-of-use patent. Patent challenges, settlements, licenses, and label carve-outs can also change the real-world launch date. This page shows the underlying Orange Book dates so you can see why estimates may differ.
What does “FDA listed” mean?
It means the product appears in the FDA’s official NDC directory. That’s a good sign a product exists and is intended for the U.S. market, but on its own it does not confirm a pharmacy can fill it today. Where we have recent retail pricing data (NADAC) for a product, 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 Orange Book for a patent or exclusivity on the brand product. It can affect when a full generic version becomes widely available — but it is not a guaranteed generic launch date. Generics sometimes arrive earlier (through a settlement or patent challenge) or later (a manufacturer still has to make and sell one).
What does “current Orange Book estimate” mean?
It means we are using the latest patent and exclusivity dates currently listed in the FDA Orange Book. It is not a guaranteed launch date.
Can a generic come out before the last patent expires?
Sometimes. A generic company may challenge a patent, settle with the brand manufacturer, receive a license, or obtain approval with a narrower label that avoids a patented use. In other cases, the last listed protection may delay full-label generic competition.
Can a generic come out after the listed dates?
Yes. Even after patents or exclusivity expire, a generic still needs FDA approval and a manufacturer must choose to market it. Supply, litigation, business decisions, or regulatory issues can delay actual availability.
What is the difference between patents and exclusivity?
Patents are legal protections usually issued by the U.S. Patent and Trademark Office. FDA exclusivity is marketing protection granted by the FDA. They are separate, and either one can affect generic timing.
Why are there multiple patent dates?
One drug can have several patents covering different things: the active ingredient, a formulation, a manufacturing process, or a specific approved use. That is why a page may show several expiration dates instead of one simple generic date.
Built from FDA Orange Book patent and exclusivity data. Dates are refreshed from public FDA data when available; the marker is max(latest patent expiry, latest exclusivity expiry). Paragraph-IV settlements and first-filer 180-day exclusivity can shift the real date; a method-of-use patent may allow an earlier skinny-label generic for non-protected indications. Generic launch timing is an estimate, not a guarantee.
Where does this data come from?
Patents and exclusivity from the FDA Orange Book (small-molecule drugs), refreshed from public FDA data. Generic launch timing is an estimate, not a guarantee.

🎯 Indications and Usage 74 words ▾

1 INDICATIONS AND USAGE AURLUMYN is a prostacyclin mimetic indicated for the treatment of severe frostbite in adults to reduce the risk of digit amputations. Effectiveness was established in young, healthy adults who suffered frostbite at high altitudes ( 1.1 ).

1.1Frostbite AURLUMYN is indicated for the treatment of severe frostbite in adults to reduce the risk of digit amputations. Effectiveness was established in young, healthy adults who suffered frostbite at high altitudes.

⏱️ Dosage and Administration ~3 min read ▾

2 DOSAGE AND ADMINISTRATION Initiate intravenous infusion at 0.5 ng/kg/minute and titrate in 0.5 ng/kg/minute increments based on tolerability at intervals of 30 minutes to a maximum of 2 ng/kg/minute ( 2.1 ). Administer as continuous infusion for 6 hours each day up to a maximum of 8 consecutive days ( 2.1 ). Patients with moderate or severe hepatic impairment (Child-Pugh Class B or C): initiate infusion at 0.25 ng/kg/minute and titrate as described above ( 2.3 ).

Patients with renal impairment with eGFR less than 30 mL/min: initiate infusion at 0.5 ng/kg/minute and titrate as described above. If the patient cannot tolerate the starting dose of 0.5 ng/kg/minute, the dose can be decreased to 0.25 ng/kg/minute ( 2.4 ). See Full Prescribing Information for instructions on preparation and administration ( 2.2 ).

2.1Recommended Dosage Monitor vital signs prior to the start of the infusion and with every dose increase. Administer AURLUMYN as a continuous intravenous infusion over 6 hours each day for up to a maximum of 8 consecutive days. Start the initial infusion on day 1 at a rate of 0.5 ng/kg/minute and increase in increments of 0.5 ng/kg/minute every 30 minutes according to tolerability up to 2 ng/kg/minute.

Dosage is based on actual patient body weight (kg). Repeat dose titration steps on day 2 and day 3. From day 4 onward, start the infusion at the highest tolerated dose from the previous day, and adjust the rate as needed, based on tolerability.

Adverse reactions such as headache, flushing, jaw pain, myalgia, nausea, and vomiting may be dose-limiting. If dose-limiting adverse reactions occur that cannot be tolerated by the patient, then decrease the dose in a stepwise manner by 0.5 ng/kg/min every 30 minutes, until a tolerated dose is reached. If a dose-limiting adverse reaction occurs during administration of AURLUMYN at the starting dose, the infusion should be discontinued, and re-initiation of the infusion can be attempted after the event has resolved or been treated.

If infusion is stopped at any point for a dose-limiting adverse event, infusion can be reinitiated at a previously tolerated dose/infusion rate once the event has resolved. The maximum tolerated dose should be maintained for the remaining 6-hour daily infusion.

2.2Preparation and Administration Preparation: Use aseptic technique to prepare AURLUMYN. Inspect the vial for particulate matter prior to administration. Do not use if the solution is discolored or cloudy or if foreign particles are present.

Dilution: AURLUMYN should only be diluted using 0.9% Sodium Chloride Injection, USP. Do not dilute or mix AURLUMYN with any other parenteral medications or solutions prior to or during administration. Withdraw 1 mL (100 mcg) of AURLUMYN solution from the vial and transfer into 100 mL of 0.9% Sodium Chloride Injection, USP polyvinyl chloride (PVC) infusion bag to make a final concentration of 1 mcg/mL (1,000 ng/mL).

AURLUMYN can be added to commercially available infusion bags labeled to contain 100 mL of 0.9% Sodium Chloride Injection, USP. Gently mix the intravenous bag by slowly inverting the bag. Do not shake.

Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration, whenever solution and container permit. Do not use if visibly opaque particles, discoloration, or foreign particles are observed. Immediately use diluted AURLUMYN infusion solution.

If not used immediately, the diluted solution can be stored at room temperature (20°C to 25°C [68°F to 77°F]) for up to 4 hours. Administration Administer AURLUMYN as an intravenous infusion through a peripheral line or peripherally inserted central catheter using an infusion pump. Use an infusion set with an in-line 0.22- or 0.2-micron filter.

Once diluted, AURLUMYN should be administered with an infusion pump that can support the minimum and maximum flow rates. The infusion pump used to administer AURLUMYN should: (1) be able to deliver rates 0.1 to 99… [Excerpted — this section continues on DailyMed.]

🤒 Adverse Reactions 192 words ▾

6 ADVERSE REACTIONS Most common adverse events include headache, flushing, palpitations/tachycardia, nausea, vomiting, dizziness, and hypotension (6.1). To report SUSPECTED ADVERSE REACTIONS, contact BTG International, Inc. at 1-877-377-3748 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch.

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. Adverse events reported with the use of intravenous iloprost in patients with frostbite from the published literature include headache, flushing, palpitations/tachycardia, nausea, vomiting, dizziness, and hypotension. Pre-marketing safety data on AURLUMYN were obtained from 116 patients with Systemic Sclerosis receiving iloprost in 2 multicenter, double-blind, randomized, placebo-controlled studies in patients with Systemic Sclerosis experiencing symptomatic digital ischemic episodes (Raynaud's Phenomenon).

Patients received intravenous AURLUMYN administered as a continuous infusion over 6 hours each day for 5 consecutive days and the dose was adjusted according to individual tolerability within the range of 0.5 to 2.0 ng /kg /min. The observed safety profile in these patients was similar to that observed with IV iloprost.

👥 Use in Specific Populations ~3 min read ▾

8 USE IN SPECIFIC POPULATIONS Lactation: Advise not to breastfeed ( 8.2 ).

8.1Pregnancy Risk Summary There are no available data with AURLUMYN during pregnancy to evaluate for a drug-associated risk of major birth defects, miscarriage, or adverse maternal or fetal outcomes. There are limited published cases of inhaled iloprost use during pregnancy, primarily during the second and third trimesters, that have not identified a drug-associated risk of adverse maternal or fetal outcomes. In animal reproductive studies, administration of continuous intravenous iloprost to pregnant Han-Wistar rats during organogenesis at doses 2-times the maximum recommended human dose on a mg/m 2 basis resulted in adverse developmental outcomes.

However, there were no adverse developmental outcomes with oral or intravenous administration of iloprost to pregnant Sprague-Dawley rats, rabbits, and monkeys at doses 1111-, 1061-, and 12-times, respectively, the maximum recommended human dose by Cmax ( see Data ). The 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 US 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. Data Animal Data In developmental toxicity studies in pregnant Han-Wistar rats, continuous intravenous administration of iloprost at a dosage of 0.01 mg/kg daily (2 times the maximum recommended human dose on a mg/m 2 basis, serum levels not available) led to shortened digits of the thoracic extremity in fetuses and pups. In similar studies in pregnant Sprague-Dawley rats that received iloprost clathrate (13% iloprost by weight) orally at dosages of up to 50 mg/kg/day (C max of 90 ng/mL), in pregnant rabbits at intravenous dosages of up to 0.5 mg/kg/day (C max of 86 ng/mL), and in pregnant monkeys at dosages of up to 0.04 mg/kg/day (serum levels of 1 ng/mL), at 1111-, 1062- and 12-times, respectively, the maximum recommended human dose by Cmax, no such digital anomalies or other gross-structural abnormalities were observed in the fetuses/pups.

However, in gravid Sprague-Dawley rats, iloprost clathrate (13% iloprost) significantly increased the number of non-viable fetuses at a maternally toxic oral dosage of 250 mg/kg/day (729 times the maximum recommended human dose on a mg/m 2 basis) and in Han-Wistar rats was found to be embryolethal in 15 of 44 litters at an intravenous dosage of 1 mg/kg/day (225 times the maximum recommended human dose on a mg/m 2 basis).

8.2Lactation Risk Summary There are no data on the presence of iloprost in human milk, the effects on the breastfed infant, or the effects on milk production. Iloprost is present in rat milk ( see Data ). When a drug is present in animal milk, it is likely that the drug will be present in human milk.

Because of the potential for serious adverse reactions, advise women not to breastfeed during treatment with iloprost [see Warnings and Precautions ( 5 ) and Adverse Reactions ( 6 )] . Data In studies with Han-Wistar rats, higher mortality was observed in pups of lactating dams receiving iloprost intravenously at 1 mg/kg daily (at 225 times the maximum recommended human dose on a mg/m 2 basis). In Sprague-Dawley rats, higher mortality was also observed in nursing pups at a maternally toxic oral dose of 250 mg/kg/day of iloprost clathrate (13% iloprost by weight) (729 times the maximum recommended human dose on a mg/m 2 basis).

In rats, a passage of low levels of iloprost or metabolites into the milk was observed (less than 1% of iloprost dose given intravenously). No disturbance of post-natal development and reproductive performance was seen in animals exposed during lactation.

8.4Pediatric Use Safety and efficacy in pediatric patients have not been established.

In the US 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. Data Animal Data In developmental toxicity studies in pregnant Han-Wistar rats, continuous intravenous administration of iloprost at a dosage of 0.01 mg/kg daily (2 times the maximum recommended human dose on a mg/m 2 basis, serum levels not available) led to shortened digits of the thoracic extremity in fetuses and pups. In similar studies in pregnant Sprague-Dawley rats that received iloprost clathrate (13% iloprost by weight) orally at dosages of up to 50 mg/kg/day (C max of 90 ng/mL), in pregnant rabbits at intravenous dosages of up to 0.5 mg/kg/day (C max of 86 ng/mL), and in pregnant monkeys at dosages of up to 0.04 mg/kg/day (serum levels of 1 ng/mL), at 1111-, 1062- and 12-times, respectively, the maximum recommended human dose by Cmax, no such digital anomalies or other gross-structural abnormalities were observed in the fetuses/pups.

However, in gravid Sprague-Dawley rats, iloprost clathrate (13% iloprost) significantly increased the number of non-viable fetuses at a maternally toxic oral dosage of 250 mg/kg/day (729 times the maximum recommended human dose on a mg/m 2 basis) and in Han-Wistar rats was found to be embryolethal in 15 of 44 litters at an intravenous dosage of 1 mg/kg/day (225 times the maximum recommended human dose on a mg/m 2 basis).

🧓 Geriatric Use 85 words ▾

8.5Geriatric Use Clinical studies of iloprost did not include sufficient numbers of subjects aged 65 years and older to determine whether they respond differently than younger subjects. Other reported clinical experience with iloprost has not identified differences in responses between 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 35 words ▾

10 OVERDOSAGE Cases of overdose of intravenous iloprost have not been reported. Hypotension, vomiting, and diarrhea are likely. A specific antidote is not known. Interruption of the infusion session, monitoring, and symptomatic measures are recommended.

12 CLINICAL PHARMACOLOGY

12.1Mechanism of Action Iloprost is a synthetic analog of prostacyclin PGI 2 . Iloprost is a vasodilator and inhibits platelet aggregation.

12.3Pharmacokinetics General Iloprost administered intravenously has linear pharmacokinetics over the dose range of 1 to 3 ng/kg/min. The half-life of iloprost is 20 to 30 minutes. Absorption and Distribution Following intravenous infusion, the apparent steady-state volume of distribution was 0.7 to

0.8L/kg in healthy subjects. Iloprost is approximately 60% protein-bound, mainly to albumin, and this ratio is concentration-independent in the range of 30 to 3000 pg/mL. Metabolism and Excretion In vitro studies reveal that cytochrome P450-dependent metabolism plays only a minor role in the biotransformation of iloprost.

Iloprost is metabolized principally via β-oxidation of the carboxyl side chain. The main metabolite is tetranor-iloprost, which is found in the urine in free and conjugated form. In animal experiments, tetranor-iloprost was pharmacologically inactive.

Clearance in normal subjects was approximately 20 mL/min/kg. A mass-balance study using intravenously and orally administered [ 3 H]-iloprost in healthy subjects (n = 8) showed recovery of 81% of total radioactivity over 14 hours post-dose, with 68% and 12% recoveries in urine and feces, respectively. Drug Interactions Intravenous infusion of iloprost had no effect on the pharmacokinetics of digoxin.

Acetylsalicylic acid did not alter the clearance (pharmacokinetics) of iloprost.

📋 Description 193 words ▾

11 DESCRIPTION AURLUMYN contains iloprost, a synthetic analog of prostacyclin PGI 2 . The chemical name for iloprost is (5 E )-[3a S ,4 R ,5 R ,6a S )-5-hydroxy-4-[(1 E )-(3 S ,4 RS )-3-hydroxy-4-methyloct-1-en-6-ynyl]-hexahydropentalen-2(1 H )-ylidene]pentanoic acid. Iloprost consists of a mixture of the 4R and 4S diastereoisomers at a ratio of approximately 53:47.

Iloprost is an oily substance, which is soluble in methanol, ethanol, ethyl acetate, acetone, and pH 7 buffer, sparingly soluble in buffer pH 9, and very slightly soluble in distilled water, buffer pH 3, and buffer pH 5. The molecular formula of iloprost is C 22 H 32 O 4 and its molecular weight is 360.49. The structural formula is shown below: AURLUMYN (iloprost) injection is a clear, colorless, sterile solution formulated for intravenous use.

14 CLINICAL STUDIES

14.1Frostbite The efficacy of intravenous (IV) iloprost for the treatment of severe frostbite to reduce the risk of digit amputations is derived from a published open-label, randomized controlled trial that enrolled patients with severe frostbite (Cauchy et al, 2011; Cheguillaume, 2011) Cauchy, E., et al. (2011). A controlled trial of a prostacyclin and rt-PA in the treatment of severe frostbite.

N Engl J Med 364, 189-190; Cheguillaume, B. (2011). Controlled trial of iloprost and iloprost and rt-PA in the treatment of severe frostbite.

Grenoble School of Medicine Thesis. HAL, https://dumas.ccsd.cnrs.fr/dumas-00618697. . Severe frostbite was defined as having at least one digit (finger or toe) with frostbite stage 3 (lesion extending just past the proximal phalanx) or stage 4 (lesion extending proximal to the metacarpal or metatarsal joint).

The trial randomized 47 patients at a single site between 1996 and 2008. At enrollment, all eligible patients (n=47) were treated with rapid rewarming of areas with frostbite, aspirin 250 mg IV, and buflomedil 400 mg IV and then randomized to Groups A, B or C. All patients continued to receive aspirin 250 mg IV daily up to 8 days.

In addition, Group A (n=15) received buflomedil 400 mg IV for up to 8 days, Group B (n=16) received iloprost IV for 6 hours daily for up to 8 days, and Group C (n=16) received recombinant tissue plasminogen activator IV on Day 1 and iloprost IV for 6 hours daily for up to 8 days. The mean age of the study population was 33 years (range: 18-55 years), 94% were men, 96% sustained frostbite during sports activities, 6% had history of smoking, and none had diabetes. At randomization, 70% of the patients had frostbite involving the feet, 62% had frostbite involving the hands, and 32% had frostbite involving both feet and hands.

The primary endpoint was the presence of an anomaly (absence of uptake) in the bone phase of technetium 99m scan performed 7 days after initial clinical presentation of frostbite (BS2 bone scintigraphy anomaly) in at least one finger/toe affected by severe frostbite. The BS2 bone scintigraphy anomaly is expected to predict risk of amputation. On day 7, the presence of BS2 bone scintigraphy anomaly was observed in 60% (9/15), 0% (0/16) and 19% (3/16) of the patients in Groups A, B, and C, respectively.

Compared to Group A, the presence of bone scintigraphy anomaly was significantly lower in Group B (p < 0.001) and Group C (p<0.03), favoring iloprost. Additional follow-up data confirming amputation were obtained for 40/47 patients, which was concordant with the bone scintigraphy results.

13 NONCLINICAL TOXICOLOGY

13.1Carcinogenesis, Mutagenesis, Impairment of Fertility Iloprost was not mutagenic in bacterial and mammalian cells in the presence or absence of extrinsic metabolic activation. Iloprost did not cause chromosomal aberrations in vitro in human lymphocytes and was not clastogenic in vivo in NMRI/SPF mice. There was no evidence of a tumorigenic effect of iloprost clathrate (13% iloprost by weight) in Sprague-Dawley rats dosed orally for up to 8 months at doses of up to 125 mg/kg/day (C max of 45 ng/mL serum, 556 times the C max at maximum recommended human dose), followed by 16 months at 100 mg/kg/day , or in Crl:CD-1 ® (ICR)BR albino mice dosed orally for up to 24 months at doses of up to 125 mg/kg/day (C max of 156 ng/mL serum, 1926 times the Cmax at maximum recommended human dose).

The recommended clinical dosage regimen for iloprost (2 ng/kg/min) affords a serum C max of 0.081 ng/mL. Fertility of males or females was not impaired in Han-Wistar rats at intravenous doses up to 1 mg/kg/day, 225 times the maximum recommended daily dose of Iloprost on a mg/m 2 basis.

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 BTG International Inc. Listing status can change — the directory data on this page refreshes weekly.
Who lists this product with the FDA?
BTG International 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.
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.
