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

🎯 Indications and Usage 109 words ▾

1 INDICATIONS AND USAGE KITABIS PAK (co-packaging of tobramycin inhalation solution and PARI LC PLUS Reusable Nebulizer) is indicated for the management of cystic fibrosis in adults and pediatric patients 6 years of age and older with P. aeruginosa . Safety and efficacy have not been demonstrated in patients under the age of 6 years, patients with FEV 1 < 25% or > 75% predicted, or patients colonized with Burkholderia cepacia [see Clinical Studies ( 14 )]. KITABIS PAK contains tobramycin, an aminoglycoside antibacterial drug indicated for the management of cystic fibrosis in adults and pediatric patients 6 years of age and older with Pseudomonas aeruginosa ( 1 ).

⏱️ Dosage and Administration ~2 min read ▾

2 DOSAGE AND ADMINISTRATION KITABIS PAK is a co-packaging of tobramycin inhalation solution with a PARI LC PLUS ® Reusable Nebulizer ( 2.1 ). Administer tobramycin inhalation solution as one single–use ampule (300 mg/5 mL) twice a day by oral inhalation in alternating periods of 28 days on drug, followed by 28 days off drug ( 2.1 ). Dosage is not adjusted by weight ( 2.1 ).

Take doses as close to 12 hours apart as possible; but not less than 6 hours apart ( 2.1 ). Administer each 300 mg dose using the PARI LC PLUS Reusable Nebulizer and DeVilbiss ® Pulmo-Aide ® compressor ( 2.2 ).

2.1Dosing Information KITABIS PAK is a co-packaging of tobramycin inhalation solution ampules with a PARI LC PLUS Reusable Nebulizer. Administer as follows: One single-use ampule (300 mg/5 mL) of tobramycin inhalation solution twice a day by oral inhalation in alternating periods of 28 days on drug, followed by 28 days off drug. The 300 mg/5 mL dose of tobramycin inhalation solution is the same for all patients regardless of age or weight.

The doses should be taken as close to 12 hours apart as possible; they should not be taken less than 6 hours apart.

2.2Administration of Tobramycin Inhalation Solution Each dose of tobramycin inhalation solution is administered by oral inhalation using only the co-packaged PARI LC PLUS Reusable Nebulizer (Model No. 022B81-T) included in the KITABIS PAK, along with a DeVilbiss Pulmo-Aide air compressor (Model No. 5650D).

Tobramycin inhalation solution is not for subcutaneous, intravenous or intrathecal administration. Prior to administration, read the Patient Information / Instructions for Use for KITABIS PAK for detailed information on how to use KITABIS PAK and follow the manufacturer's instructions for use and care of the DeVilbiss Pulmo-Aide air compressor. The entire tobramycin inhalation solution treatment should take approximately 15 minutes to complete.

Continue treatment until all the tobramycin inhalation solution has been delivered, and there is no longer any mist being produced. Tobramycin inhalation solution should not be diluted or mixed with other drugs including dornase alfa in the nebulizer. Instruct patients on multiple therapies to take their medications prior to inhaling the tobramycin inhalation solution, or as directed by their physician.

Tobramycin inhalation solution should not be used if it is cloudy, if there are particles in the solution, or if it has been stored at room temperature for more than 28 days.

⚠️ Warnings and Cautions ~2 min read ▾

5 WARNINGS AND PRECAUTIONS Bronchospasm: Can occur with inhalation of tobramycin inhalation solution. Treat as medically appropriate, if it occurs ( 5.1 ). Ototoxicity: Tinnitus and hearing loss have been reported in patients receiving tobramycin inhalation solution.

If noted, manage as medically appropriate, including potentially discontinuing tobramycin inhalation solution ( 5.2 ). Nephrotoxicity: Has been associated with aminoglycosides as a class. If nephrotoxicity develops, manage the patient as medically appropriate, including potentially discontinuing tobramycin inhalation solution ( 5.3 ).

Neuromuscular Disorders: Aminoglycosides may aggravate muscle weakness because of a potential curare-like effect on neuromuscular function. If neuromuscular blockade occurs, it may be reversed by the administration of calcium salts but mechanical assistance may be necessary ( 5.4 ). Embryo-Fetal Toxicity : Aminoglycosides can cause fetal harm ( 5.5 , 8.1 )

5.1Bronchospasm Bronchospasm can occur with inhalation of tobramycin inhalation solution. In clinical studies with tobramycin inhalation solution, changes in FEV1 measured after the inhaled dose were similar in tobramycin inhalation solution and placebo groups. Bronchospasm that occurs during the use of tobramycin inhalation solution should be treated as medically appropriate.

5.2Ototoxicity Ototoxicity with use of Tobramycin Inhalation Solution Transient tinnitus occurred in eight tobramycin inhalation solution treated patients versus no placebo patients in the clinical studies. Tinnitus may be a sentinel symptom of ototoxicity, and therefore the onset of this symptom warrants further clinical investigation. In postmarketing experience, patients receiving tobramycin inhalation solution have reported hearing loss.

Ototoxicity, manifested as both auditory and vestibular toxicity, has been reported with parenteral aminoglycosides. Vestibular toxicity may be manifested by vertigo, ataxia or dizziness. Patients with known or suspected auditory or vestibular dysfunction should be closely monitored when taking tobramycin inhalation solution.

Monitoring might include obtaining audiometric evaluations and serum tobramycin levels. If ototoxicity is noted, the patient should be managed as medically appropriate, including potentially discontinuing tobramycin inhalation solution [see Adverse Reactions ( 6.2 )] . Risk of Ototoxicity Due to Mitochondrial DNA Variants Cases of ototoxicity with aminoglycosides have been observed in patients with certain variants in the mitochondrially encoded 12S rRNA gene ( MT-RNR1 ), particularly the m.1555A>G variant.

Ototoxicity occurred in some patients even when their aminoglycoside serum levels were within the recommended range. Mitochondrial DNA variants are present in less than 1% of the general US population, and the proportion of the variant carriers who may develop ototoxicity as well as the severity of ototoxicity is unknown. In case of known maternal history of ototoxicity due to aminoglycoside use or a known mitochondrial DNA variant in the patient, consider alternative treatments other than aminoglycosides unless the increased risk of permanent hearing loss is outweighed by the severity of infection and lack of safe and effective alternative therapies.

5.3Nephrotoxicity Nephrotoxicity was not seen during clinical studies with tobramycin inhalation solution but has been associated with aminoglycosides as a class. Patients with known or suspected renal dysfunction or taking concomitant nephrotoxic drugs along with tobramycin inhalation solution should have serum concentrations of tobramycin and laboratory measurements of renal function obtained at the discretion of the treating physician. If nephrotoxicity develops, the patient should be managed as medically appropriate, including potentially discontinuing tobramycin inhalation solution.

5.4Neuromuscular Disorders Aminoglycosides, including tobramycin, may aggravate muscle weakness because of a p… [Excerpted — this section continues on DailyMed.]

🤒 Adverse Reactions ~2 min read ▾

6 ADVERSE REACTIONS The following serious adverse reactions are described below and elsewhere in the labeling: Bronchospasm [see Warnings and Precautions ( 5.1 )] Ototoxicity [see Warnings and Precautions ( 5.2 )] The most common adverse reactions (> 5%) in patients treated with tobramycin inhalation solution were increased cough, pharyngitis, increased sputum, dyspnea, hemoptysis, decreased lung function, voice alteration, taste perversion and rash ( 6.1 ). To report SUSPECTED ADVERSE REACTIONS, contact PARI Respiratory Equipment at 1-844-548-2247 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch

6.1Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice. Tobramycin inhalation solution was studied in two clinical studies in 258 cystic fibrosis patients ranging in age from 6 to 48 years. Patients received tobramycin inhalation solution in alternating periods of 28 days on and 28 days off drug in addition to their standard cystic fibrosis therapy for a total of 24 weeks.

Adverse reactions reported in these studies are described below: The most frequent adverse reactions in the tobramycin inhalation arm were cough, pharyngitis, and increased sputum (see Table 1 ). Thirty-three patients (13%) treated with tobramycin inhalation solution complained of voice alteration compared to 17 (7%) placebo patients. Voice alteration was more common in the on-drug periods.

Eight patients from the tobramycin inhalation solution group (3%) reported tinnitus compared to no placebo patients. All episodes were transient, resolved without discontinuation of the tobramycin inhalation solution treatment regimen, and were not associated with loss of hearing in audiograms. Table 1 lists the percent of patients with selected adverse reactions that occurred in > 5% of tobramycin inhalation solution patients during the two Phase III studies.

Table 1: Percent of Patients with Selected Adverse Reactions Occurring in > 5% of Tobramycin Inhalation Solution Patients 1 Includes reported decreases in pulmonary function tests or decreased lung volume on chest radiograph associated with intercurrent illness or study drug administration.

6.2Postmarketing Experience The following adverse reactions have been identified during post approval use of tobramycin inhalation solution. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure. Ear and labyrinth disorders Hearing loss: Some of these reports occurred in patients with previous or concomitant treatment with systemic aminoglycosides.

Patients with hearing loss frequently reported tinnitus.

🔄 Drug Interactions 107 words ▾

7 DRUG INTERACTIONS Concurrent and/or sequential use with other drugs with neurotoxic, nephrotoxic or ototoxic potential should be avoided ( 7.1 ). Concomitant administration with ethacrynic acid, furosemide, urea, or intravenous mannitol is not recommended due to possible enhancement of aminoglycoside toxicity ( 7.2 ).

7.1Drugs with Neurotoxic, Nephrotoxic or Ototoxic Potential Concurrent and/or sequential use of tobramycin inhalation solution with other drugs with neurotoxic, nephrotoxic, or ototoxic potential should be avoided if possible.

7.2Diuretics Some diuretics can enhance aminoglycoside toxicity by altering aminoglycoside concentrations in serum and tissue. Tobramycin inhalation solution should not be administered concomitantly with ethacrynic acid, furosemide, urea, or intravenous mannitol.

👥 Use in Specific Populations ~2 min read ▾

8 USE IN SPECIFIC POPULATIONS

8.1Pregnancy Risk Summary Aminoglycosides can cause fetal harm. Published literature reports that use of streptomycin, an aminoglycoside, can cause total, irreversible, bilateral congenital deafness when administered to a pregnant woman [Warnings and Precautions ( 5.5 )] . Although there are no available data on KITABIS PAK use in pregnant women to inform a drug-associated risk of major birth defects, miscarriage, or adverse maternal or fetal outcomes, systemic absorption of tobramycin following inhaled administration is expected to be minimal [see Clinical Pharmacology ( 12.3 )] .

There are risks to the mother associated with cystic fibrosis in pregnancy (see Clinical Considerations ) . In animal reproduction studies with subcutaneous administration of tobramycin in pregnant rats and rabbits during organogenesis there were no adverse developmental outcomes; however, ototoxicity was not evaluated in the offspring from these studies ( see Data ). Advise pregnant women of the potential risk to a fetus.

The estimated background risk of major birth defects and miscarriage for the indicated populations are 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 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 Cystic fibrosis may increase the risk for preterm delivery. Data Animal Data No reproductive toxicity studies have been conducted with tobramycin inhalation solution. However, subcutaneous administration of tobramycin at doses of up to 100 (rat) or 20 (rabbit) mg/kg/day during organogenesis was not associated with adverse developmental outcomes.

Subcutaneous doses of tobramycin ≥40 mg/kg/day were severely maternally toxic to rabbits and precluded the evaluation of adverse developmental outcomes. Ototoxicity was not evaluated in offspring during non-clinical reproductive toxicity studies with tobramycin.

8.2Lactation Risk Summary There are no data on the presence of tobramycin inhalation solution in either human or animal milk, the effects on the breastfed infant, or the effects on milk production. Limited published data on other formulations of tobramycin in lactating women indicate that tobramycin is present in human milk. However, systemic absorption of tobramycin following inhaled administration is expected to be minimal [see Clinical Pharmacology ( 12.3 )] .

Tobramycin may cause alteration in the intestinal flora of the breastfeeding infant (see Clinical Considerations ) . The developmental and health benefits of breastfeeding should be considered along with the mother's clinical need for KITABIS PAK and any potential adverse effects on the breastfed infant from KITABIS PAK or from the underlying maternal condition. Clinical Considerations Tobramycin may cause intestinal flora alteration.

Advise a woman to monitor the breastfed infant for loose or bloody stools and candidiasis (thrush, diaper rash).

8.4Pediatric Use The safety and efficacy of tobramycin inhalation solution have not been studied in pediatric patients under 6 years of age.

8.5Geriatric Use Clinical studies of tobramycin inhalation solution did not include patients aged 65 years and over. Tobramycin is known to be substantially excreted by the kidney, and the risk of adverse reactions to this drug may be greater in patients with impaired renal function. Because elderly patients are more likely to have decreased renal function, it may be useful to monitor renal function [see Warnings and Precautions ( 5.3 )].

Tobramycin is known to be substantially excreted by the kidney, and the risk of adverse reactions to this drug may be greater in patients with impaired renal function. Because elderly patients are more likely to have decreased renal function, it may be useful to monitor renal function [see Warnings and Precautions ( 5.3 )].

🆘 Overdosage 55 words ▾

10 OVERDOSAGE Signs and symptoms of acute toxicity from overdosage of IV tobramycin might include dizziness, tinnitus, vertigo, loss of high-tone hearing acuity, respiratory failure, and neuromuscular blockade. Administration by inhalation results in low systemic bioavailability of tobramycin. Tobramycin is not significantly absorbed following oral administration. Tobramycin serum concentrations may be helpful in monitoring overdosage.

12 CLINICAL PHARMACOLOGY

12.1Mechanism of Action Tobramycin is an aminoglycoside antibacterial [see Microbiology ( 12.4 ) ].

12.3Pharmacokinetics Absorption Tobramycin inhalation solution contains tobramycin, a cationic polar molecule that does not readily cross epithelial membranes. 1 The bioavailability of tobramycin inhalation solution may vary because of individual differences in nebulizer performance and airway pathology. 2 Following administration of tobramycin inhalation solution, tobramycin remains concentrated primarily in the airways.

Sputum Concentrations Ten minutes after inhalation of the first 300 mg dose of tobramycin inhalation solution, the average concentration of tobramycin was 1237 mcg/g (ranging from 35 to 7414 mcg/g) in sputum. Tobramycin does not accumulate in sputum; after 20 weeks of therapy with the tobramycin inhalation solution regimen, the average concentration of tobramycin at ten minutes after inhalation was 1154 mcg/g (ranging from 39 to 8085 mcg/g) in sputum. High variability of tobramycin concentration in sputum was observed.

Two hours after inhalation, sputum concentrations declined to approximately 14% of tobramycin levels at ten minutes after inhalation. Serum Concentrations The average serum concentration of tobramycin one hour after inhalation of a single 300 mg dose of tobramycin inhalation solution by cystic fibrosis patients was 0.95 mcg/mL. After 20 weeks of therapy on the tobramycin inhalation solution regimen, the average serum tobramycin concentration one hour after dosing was 1.05 mcg/mL.

Distribution Following administration of tobramycin inhalation solution, tobramycin remains concentrated primarily in the airways. Binding of tobramycin to serum proteins is negligible. Elimination Metabolism Tobramycin is not metabolized.

Excretion The elimination half-life of tobramycin from serum is approximately 2 hours after intravenous (IV) administration. Assuming tobramycin absorbed following inhalation behaves similarly to tobramycin following IV administration, systemically absorbed tobramycin is eliminated principally by glomerular filtration. Unabsorbed tobramycin, following tobramycin inhalation solution administration, is likely eliminated primarily in expectorated sputum.

12.4Microbiology Mechanism of Action Tobramycin is an aminoglycoside antibacterial produced by Streptomyces tenebrarius . It acts primarily by disrupting protein synthesis, leading to altered cell membrane permeability, progressive disruption of the cell envelope, and eventual cell death. 3 ​ Tobramycin has in vitro activity against Gram-negative bacteria including P. aeruginosa .

It is bactericidal in vitro at peak concentrations equal to or slightly greater than the minimum inhibitory concentration. Resistance Treatment for 6 months with tobramycin inhalation solution in two clinical studies did not affect the susceptibility of the majority of P. aeruginosa isolates tested; however, increased minimum inhibitory concentrations (MICs) were noted in some patients. The clinical significance of this information has not been clearly established in the treatment of P. aeruginosa in cystic fibrosis patients [see Clinical Studies ( 14 )] .

Susceptibility Testing Interpretive criteria for inhaled antibacterial products are not defined. The in vitro antimicrobial susceptibility test methods used for parenteral tobramycin therapy can be used to monitor the susceptibility of P. aeruginosa isolated from cystic fibrosis patients. 4,5,6 If decreased susceptibility is noted, the results should be reported to the clinician.

Susceptibility breakpoints established for parenteral administration of tobramycin do not apply to aerosolized administration of tobramycin inhalation solution. The relationship between in vitro susceptibility test results and clinical outcome with tobramycin inhalation solution therapy is not clear. A single sputum sample from a cystic fibrosis patient may contain multiple morphotypes of Pseudomonas aerugi… [Excerpted — this section continues on DailyMed.]

🔬 Clinical Studies ~2 min read ▾

14 CLINICAL STUDIES Two identically designed, double-blind, randomized, placebo-controlled, parallel group, 24-week clinical studies (Study 1 and Study 2) at a total of 69 cystic fibrosis centers in the United States were conducted in cystic fibrosis patients with P. aeruginosa with tobramycin inhalation solution. Subjects who were less than 6 years of age, had a baseline creatinine of > 2 mg/dL, or had B. cepacia isolated from sputum were excluded. All subjects had baseline FEV 1 % predicted between 25% and 75%.

In these clinical studies, 258 patients received tobramycin inhalation solution therapy on an outpatient basis (see Table 2 ) using a PARI LC PLUS nebulizer along with a DeVilbiss Pulmo-Aide compressor. Table 2: Dosing Regimens in Clinical Studies Cycle 1 Cycle 2 Cycle 3 28 days 28 days 28 days 28 days 28 days 28 days TOBRAMYCIN Inhalation Solution regimen n=258 TOBRAMYCIN Inhalation Solution 300 mg twice daily No drug TOBRAMYCIN Inhalation Solution 300 mg twice daily No drug TOBRAMYCIN Inhalation Solution 300 mg twice daily No drug Placebo regimen n=262 Placebo twice daily Placebo twice daily Placebo twice daily All patients received either tobramycin inhalation solution or placebo (saline with 1.25 mg quinine for flavoring) in addition to standard treatment recommended for cystic fibrosis patients, which included oral and parenteral anti-pseudomonal therapy, Beta 2-agonists, cromolyn, inhaled steroids, and airway clearance techniques.

In addition, approximately 77% of patients were concurrently treated with dornase alfa. In each study, tobramycin inhalation solution-treated patients experienced significant improvement in pulmonary function. Improvement was demonstrated in the tobramycin inhalation solution group in Study 1 by an average increase in FEV 1 % predicted of about 11% relative to baseline (Week 0) during 24 weeks compared to no average change in placebo patients.

In Study 2, tobramycin inhalation solution-treated patients had an average increase of about 7% compared to an average decrease of about 1% in placebo patients. Figure 1 shows the average relative change in FEV 1 % predicted over 24 weeks for both studies. Figure 1: Relative Change From Baseline in FEV 1 % Predicted In each study, tobramycin inhalation solution therapy resulted in a significant reduction in the number of P. aeruginosa colony forming units (CFUs) in sputum during the on-drug periods.

Sputum bacterial density returned to baseline during the off-drug periods. Reductions in sputum bacterial density were smaller in each successive cycle. (see Figure 2 ).

Figure 2: Absolute Change From Baseline in Log 10 CFUs Patients treated with tobramycin inhalation solution were hospitalized for an average of 5.1 days compared to 8.1 days for placebo patients. Patients treated with tobramycin inhalation solution required an average of 9.6 days of parenteral anti-pseudomonal antibiotic treatment compared to 14.1 days for placebo patients. During the 6 months of treatment, 40% of tobramycin inhalation solution patients and 53% of placebo patients were treated with parenteral anti-pseudomonal antibiotics.

The relationship between in vitro susceptibility test results and clinical outcome with tobramycin inhalation solution therapy is not clear. However, 4 tobramycin inhalation solution patients who began the clinical trial with P. aeruginosa isolates having MIC values ≥ 128 μg/mL did not experience an improvement in FEV 1 or a decrease in sputum bacterial density.

13 NONCLINICAL TOXICOLOGY

13.1Carcinogenesis, Mutagenesis, Impairment of Fertility A two-year rat inhalation toxicology study to assess carcinogenic potential of tobramycin inhalation solution has been completed. Rats were exposed to tobramycin inhalation solution for up to 1.5 hours per day for 95 weeks. The clinical formulation of the drug was used for this carcinogenicity study.

Serum levels of tobramycin of up to 35 mcg/mL were measured in rats, in contrast to the average 1 mcg/mL levels observed in cystic fibrosis patients in clinical trials. There was no drug-related increase in the incidence of any variety of tumor. Additionally, tobramycin has been evaluated for genotoxicity in a battery of in vitro and in vivo tests.

The Ames bacterial reversion test, conducted with 5 tester strains, failed to show a significant increase in revertants with or without metabolic activation in all strains. Tobramycin was negative in the mouse lymphoma forward mutation assay, did not induce chromosomal aberrations in Chinese hamster ovary cells, and was negative in the mouse micronucleus test. Subcutaneous administration of up to 100 mg/kg of tobramycin did not affect mating behavior or cause impairment of fertility in male or female rats.

Medicaid utilization & spend

📍 This exact package only: Medicaid data is reported per full 11-digit NDC — labeler, product and pack size — so every number here is for this package alone, not the drug overall. Other pack sizes report separately.
💊 Pharmacy benefit only: These are Medicaid outpatient pharmacy claims, billed by NDC. They exclude the medical benefit — clinic- or hospital-administered drugs billed under HCPCS J-codes — so drugs used mostly that way (e.g. Avastin, Lucentis, Keytruda) can look low or missing here. That’s expected, not an error.

💵 About the dollar figures: “reimbursed” is what Medicaid paid pharmacies before confidential manufacturer rebates, so the program’s real net cost is lower than these numbers. Fee-for-service and managed-care claims are combined unless split above. Source: CMS State Drug Utilization Data; per-100k rates use 2023 Census population estimates.

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

Medicare Part D (outpatient prescription) spending for Tobi Podhaler (matched by generic name) — the program that covers self-administered drugs. 1 manufacturer.
⚠️ 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 Tobi Podhaler. CMS lists 3 products for this generic; we show the highest-spend one. 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.

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 Pari Respiratory Equipment, Inc.. Listing status can change — the directory data on this page refreshes weekly.
Who lists this product with the FDA?
Pari Respiratory Equipment, 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 J7682 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.
