Why two NDCs? The FDA registers this code as 67296-2248-3 — 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 → 67296-2248-03. Same drug, same package — only the format differs.

🧪 Inactive Ingredients / Excipients

Inactive ingredients, also called excipients, are components of the drug product other than the active ingredient. They may include fillers, dyes, coatings, preservatives, flavors, or other formulation ingredients.

Loading inactive ingredients from the official FDA label in the background. No external source is being called by this page request.
Where does this data come from?
Source: official FDA Structured Product Labeling (SPL) via DailyMed and the openFDA label index. Structured IACT rows and label-wide narrative are kept separate; availability and product-level specificity depend on the submitted label.

Inactive ingredient FAQ

Are inactive ingredients the same for every manufacturer?
No. Inactive ingredients can differ by manufacturer, dosage form, strength, and package / product version.
Why might an inactive ingredient be missing?
Some SPLs do not provide a complete structured inactive-ingredient list, and older or unusual labels may only include the information in narrative text.
Can inactive ingredients matter?
Yes. They can matter for allergies, intolerances, dyes, gluten / lactose concerns, preservatives, and formulation differences — but confirm with a pharmacist or the manufacturer when it’s clinically important.

💲 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 eachPer 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.

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.

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.
What does the discontinued status mean for this NDC?
The labeler reported a marketing end date (or the listing was delisted), so this specific package is no longer actively marketed. Remaining stock may still be dispensed for a time, and the NDC stays valid for historical records and claims — but data feeds (pricing, labeling) typically stop updating for it. Other package sizes or other manufacturers' versions of the same medication may still be marketed — see the equivalents section where available.
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 FDA registers it as 67296-2248-3, which is what is printed on the packaging and shown on DailyMed. Insurance claims use a fixed 11-digit 5-4-2 format, so the short segment is padded with a leading zero: 67296-2248-03, written without dashes as 67296224803. The Identity section at the top of this page lists every form of this code.
What do the three segments of this NDC mean?
In 67296-2248-03, the first segment (67296) is the labeler code FDA assigned to Redpharm Drug; the middle segment (2248) identifies this specific product — its ingredient, strength, and dosage form; and the last segment (03) identifies this exact package size and type. Together they name one specific package of one specific product.
Who lists this product with the FDA?
Redpharm Drug 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.

🚨 Boxed Warning ~2 min read ▾

WARNING: SERIOUS NEUROPSYCHIATRIC EVENTS WARNING: SERIOUS NEUROPSYCHIATRIC EVENTS Serious neuropsychiatric (NP) events have been reported with the use of montelukast sodium tablets. The types of events reported were highly variable, and included, but were not limited to, agitation, aggression, depression, sleep disturbances, suicidal thoughts and behavior (including suicide). The mechanisms underlying NP events associated with montelukast sodium tablets use are currently not well understood [ see Warnings and Precautions ( 5.1 ) ].

Because of the risk of NP events, the benefits of montelukast sodium tablets may not outweigh the risks in some patients, particularly when the symptoms of disease may be mild and adequately treated with alternative therapies. Reserve use of montelukast sodium tablets for patients with allergic rhinitis who have an inadequate response or intolerance to alternative therapies [ see Indications and Usage ( 1.3 )]. In patients with asthma or exercise-induced bronchoconstriction, consider the benefits and risks before prescribing montelukast sodium tablets.

Discuss the benefits and risks of montelukast sodium tablets with patients and caregivers when prescribing montelukast sodium tablets. Advise patients and/or caregivers to be alert for changes in behavior or new NP symptoms when taking montelukast sodium tablets. If changes in behavior are observed, or if new NP symptoms or suicidal thoughts and/or behavior occur, advise patients to discontinue montelukast sodium tablets and contact a healthcare provider immediately [ see Warnings and Precautions ( 5.1 ) ].

WARNING: SERIOUS NEUROPSYCHIATRIC EVENTS See full prescribing information for complete boxed warning. • Serious neuropsychiatric events have been reported in patients taking montelukast sodium tablets. ( 5.1 ). • Discuss benefits and risks of montelukast sodium tablets with patients and caregivers ( 5.1 ). • Monitor for neuropsychiatric symptoms in patients taking montelukast sodium tablets ( 5.1 ). • Discontinue montelukast sodium tablets immediately if neuropsychiatric symptoms occur ( 5.1 ). • Because the benefits of montelukast sodium tablets may not outweigh the potential risk of neuropsychiatric symptoms in patients with allergic rhinitis, reserve use for patients who have an inadequate response or intolerance to alternative therapies( 1.3 , 5.1 ).

🎯 Indications and Usage ~1 min read ▾

1 INDICATIONS & USAGE Montelukast sodium tablets are a leukotriene receptor antagonist indicated for: Prophylaxis and chronic treatment of asthma in patients 15 years of age and older ( 1.1 ). Acute prevention of exercise-induced bronchoconstriction (EIB) in patients 15 years of age and older ( 1.2 ). Relief of symptoms of allergic rhinitis (AR): seasonal allergic rhinitis (SAR) in patients 15 years of age and older, and perennial allergic rhinitis (PAR) in patients 15 years of age and older.

Reserve use for patients who have an inadequate response or intolerance to alternative therapies ( 1.3 ). Limitations of Use: Not indicated to treat an acute asthma attack ( 5.2 ).

1.1Asthma Montelukast sodium tablets are indicated for the prophylaxis and chronic treatment of asthma in patients 15 years of age and older.

1.2Exercise-Induced Bronchoconstriction (EIB) Montelukast sodium tablets are indicated for prevention of exercise-induced bronchoconstriction (EIB) in patients 15 years of age and older.

1.3Allergic Rhinitis Montelukast sodium is indicated for the relief of symptoms of seasonal allergic rhinitis in patients 15 years of age and older and perennial allergic rhinitis in patients 15 years of age and older. Because the benefits of montelukast sodium tablets may not outweigh the risk of neuropsychiatric symptoms in patients with allergic rhinitis [see Warnings and Precautions ( 5.1 )], reserve use for patients who have an inadequate response or intolerance to alternative therapies.

1.4Limitations of Use Montelukast sodium is not indicated for the treatment of an acute asthma attack.

⏱️ Dosage and Administration ~2 min read ▾

2 DOSAGE & ADMINISTRATION Administration (by indications): Asthma: Once daily in the evening for patients 15 years of age and older ( 2.1 ). Acute prevention of EIB: One tablet at least 2 hours before exercise for patients 15 years of age and older ( 2.2 ). Seasonal allergic rhinitis: Once daily for patients 15 years and older ( 2.3 ).

Perennial allergic rhinitis: Once daily for patients 15 years and older ( 2.3 ). Dosage (by age): 15 years and older: one 10-mg tablet. Patients with both asthma and allergic rhinitis should take only one dose daily in the evening ( 2.4 ).

2.1Asthma For asthma, administer montelukast sodium orally once daily in the evening, with or without food. There have been no clinical trials in patients with asthma to evaluate the relative efficacy of morning versus evening dosing. The following doses are recommended: Table 1: Recommended Dosage in Asthma Age Dose Adult and adolescent patients 15 years of age and older one 10 mg tablet Patients who miss a dose should take the next dose at their regular time and should not take 2 doses at the same time.

2.2Exercise-Induced Bronchoconstriction (EIB) For prevention of EIB, administer a single dose of montelukast sodium orally at least 2 hours, before exercise. The following doses are recommended: Table 2: Recommended Dosage in Exercise-Induced Bronchoconstriction (EIB) Age Dose Adult and adolescent patients 15 years of age and older one 10 mg tablet An additional dose of montelukast sodium should not be taken within 24 hours of a previous dose. Patients already taking montelukast sodium daily for another indication (including chronic asthma) should not take an additional dose to prevent EIB.

All patients should have available for rescue a short-acting β-agonist. Daily administration of montelukast sodium for the chronic treatment of asthma has not been established to prevent acute episodes of EIB.

2.3Allergic Rhinitis For allergic rhinitis, administer montelukast sodium orally once daily without regard to time of food ingestion. Time of administration in patients with allergic rhinitis can be individualized to suit patient needs. The following doses for the treatment of symptoms of seasonal allergic rhinitis are recommended: Table 3: Recommended Dosage in Seasonal Allergic Rhinitis Age Dose Adult and adolescent patients 15 years of age and older one 10 mg tablet The following doses for the treatment of symptoms of perennial allergic rhinitis are recommended: Table 4: Recommended Dosage in Perennial Allergic Rhinitis Age Dose Adult and adolescent patients 15 years of age and older one 10 mg tablet Patients who miss a dose should take the next dose at their regular time and should not take 2 doses at the same time.

2.4Asthma and Allergic Rhinitis For patients with both asthma and allergic rhinitis, administer only one montelukast sodium dose orally once daily in the evening. Patients who miss a dose should take the next dose at their regular time and should not take 2 doses at the same time.

3 DOSAGE FORMS & STRENGTHS Montelukast sodium tablets, USP 10 mg, are beige colour, rounded square shaped, biconvex, film-coated tablet debossed with 'CL 26' on one side and plain on the other side. • Tablets: 10 mg ( 3 )

⛔ Contraindications 25 words ▾

4 CONTRAINDICATIONS Montelukast sodium is contraindicated in patients with hypersensitivity to any of its components. Hypersensitivity to any component of montelukast sodium ( 4 ).

⚠️ Warnings and Cautions ~3 min read ▾

5 WARNINGS AND PRECAUTIONS Do not prescribe montelukast sodium to treat an acute asthma attack ( 5.2 ). Advise patients to have appropriate rescue medication available ( 5.2 ). Inhaled corticosteroid may be reduced gradually.

Do not abruptly substitute montelukast sodium for inhaled or oral corticosteroids ( 5.3 ). Patients with known aspirin sensitivity should continue to avoid aspirin or non-steroidal anti-inflammatory agents while taking montelukast sodium ( 5.4 ). Systemic eosinophilia, sometimes presenting with clinical features of vasculitis consistent with Churg-Strauss syndrome, has been reported.

These events have been sometimes associated with the reduction of oral corticosteroid therapy ( 5.5 and 6.2 ).

5.1Neuropsychiatric Events Serious neuropsychiatric (NP) events have been reported with use of montelukast sodium. These postmarketing reports have been highly variable and included, but were not limited to, agitation, aggressive behavior or hostility, anxiousness, depression, disorientation, disturbance in attention, dream abnormalities, dysphemia (stuttering), hallucinations, insomnia, irritability, memory impairment, obsessive-compulsive symptoms, restlessness, somnambulism, suicidal thoughts and behavior (including suicide), tic, and tremor.

NP events have been reported in adult, adolescent, and pediatric patients with and without a previous history of psychiatric disorder. NP events have been reported mostly during montelukast sodium treatment, but some were reported after montelukast sodium discontinuation. Animal studies showed that montelukast distributes into the brain in rats [ see Clinical Pharmacology ( 12.3 ) ]; however, the mechanisms underlying montelukast sodium-associated NP events are currently not well understood.

Based upon the available data, it is difficult to identify risk factors for or quantify the risk of NP events with montelukast sodium use. Because of the risk of NP events, the benefits of montelukast sodium may not outweigh the risks in some patients, particularly when the symptoms of disease may be mild and adequately treated with alternative therapies. Reserve use of montelukast sodium for patients with allergic rhinitis who have an inadequate response or intolerance to alternative therapies [ see Indications and Usage ( 1.3 ) ].

In patients with asthma or exercise-induced bronchoconstriction, consider the benefits and risks before prescribing montelukast sodium. Discuss the benefits and risks of montelukast sodium use with patients and caregivers when prescribing montelukast sodium. Advise patients and/or caregivers to be alert for changes in behavior or for new NP symptoms when taking montelukast sodium.

If changes in behavior are observed, or if new NP symptoms or suicidal thoughts and/or behavior occur, advise patients to discontinue montelukast sodium and contact a healthcare provider immediately. In many cases, symptoms resolved after stopping montelukast sodium therapy; however, in some cases symptoms persisted after discontinuation of montelukast sodium. Therefore, continue to monitor and provide supportive care until symptoms resolve.

Re-evaluate the benefits and risks of restarting treatment with montelukast sodium if such events occur.

5.2Acute Asthma Montelukast sodium is not indicated for use in the reversal of bronchospasm in acute asthma attacks, including status asthmaticus. Patients should be advised to have appropriate rescue medication available. Therapy with montelukast sodium can be continued during acute exacerbations of asthma. Patients who have exacerbations of asthma after exercise should have available for rescue a short-acting inhaled β-agonist.

5.3Concomitant Corticosteroid Use While the dose of inhaled corticosteroid may be reduced gradually under medical supervision, montelukast sodium should not be abruptly substituted for inhaled or oral corticosteroids.

5.4Aspirin Sensitivity Patients with known aspirin sensitivity should continue avoidance of aspir…

👥 Use in Specific Populations ~3 min read ▾

8 USE IN SPECIFIC POPULATIONS

8.1Pregnancy Risk Summary Available data from published prospective and retrospective cohort studies over decades with montelukast use in pregnant women have not established a drug-associated risk of major birth defects [see Data]. In animal reproduction studies, no adverse developmental effects were observed with oral administration of montelukast to pregnant rats and rabbits during organogenesis at doses approximately 100 and 110 times, respectively, the maximum recommended human daily oral dose (MRHDOD) based on AUCs [see Data].

The estimated background risk of major birth defects and miscarriage for the indicated population 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 defects and miscarriage in clinically recognized pregnancies is 2-4% and 15-20%, respectively.

Clinical Considerations Disease-associated maternal and/or embryo/fetal risk Poorly or moderately controlled asthma in pregnancy increases the maternal risk of perinatal adverse outcomes such as preeclampsia and infant prematurity, low birth weight, and small for gestational age. Data Human Data Published data from prospective and retrospective cohort studies have not identified an association with montelukast sodium use during pregnancy and major birth defects. Available studies have methodologic limitations, including small sample size, in some cases retrospective data collection, and inconsistent comparator groups.

Animal Data In embryo-fetal development studies, montelukast administered to pregnant rats and rabbits during organogenesis (gestation days 6 to 17 in rats and 6 to 18 in rabbits) did not cause any adverse developmental effects at maternal oral doses up to 400 and 300 mg/kg/day in rats and rabbits, respectively (approximately 100 and 110 times the AUC in humans at the MRHDOD, respectively).

8.2Lactation Risk Summary A published clinical lactation study reports the presence of montelukast in human milk. Data available on the effects of the drug on infants, either directly [see Use in Specific Populations ( 8.4 )] or through breast milk, do not suggest a significant risk of adverse reactions from exposure to montelukast sodium. The effects of the drug on milk production are unknown.

The developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for montelukast sodium and any potential adverse reactions on the breastfed infant from montelukast sodium or from the underlying maternal condition.

8.4Pediatric Use The safety and effectiveness in pediatric patients below the age of 12 months with asthma, 6 months with perennial allergic rhinitis, and 6 years with exercise-induced bronchoconstriction have not been established.

8.5Geriatric Use Of the total number of subjects in clinical studies of montelukast, 3.5% were 65 years of age and over, and 0.4% were 75 years of age and over. No overall differences in safety or effectiveness were observed between these subjects and younger subjects, and other reported clinical experience has not identified differences in responses between the elderly and younger patients, but greater sensitivity of some older individuals cannot be ruled out. The pharmacokinetic profile and the oral bioavailability of a single 10-mg oral dose of montelukast are similar in elderly and younger adults.

The plasma half-life of montelukast is slightly longer in the elderly. No dosage adjustment in the elderly is required.

8.6Hepatic Impairment No dosage adjustment is recommended in patients with mild-to-moderate hepatic insufficiency [see Clinical Pharmacology ( 12.3 )].

8.7Renal Impairment No dosage adjustment is recommended in patients with renal insufficiency [see Clinical Pharmacology ( 12.3 )].

12 CLINICAL PHARMACOLOGY

12.1Mechanism of Action The cysteinyl leukotrienes (LTC 4 , LTD 4 , LTE 4 ) are products of arachidonic acid metabolism and are released from various cells, including mast cells and eosinophils. These eicosanoids bind to cysteinyl leukotriene (CysLT) receptors. The CysLT type-1 (CysLT 1 ) receptor is found in the human airway (including airway smooth muscle cells and airway macrophages) and on other pro-inflammatory cells (including eosinophils and certain myeloid stem cells).

CysLTs have been correlated with the pathophysiology of asthma and allergic rhinitis. In asthma, leukotriene-mediated effects include airway edema, smooth muscle contraction, and altered cellular activity associated with the inflammatory process. In allergic rhinitis, CysLTs are released from the nasal mucosa after allergen exposure during both early- and late-phase reactions and are associated with symptoms of allergic rhinitis.

Montelukast is an orally active compound that binds with high affinity and selectivity to the CysLT 1 receptor (in preference to other pharmacologically important airway receptors, such as the prostanoid, cholinergic, or β-adrenergic receptor). Montelukast inhibits physiologic actions of LTD 4 at the CysLT 1 receptor without any agonist activity.

12.2Pharmacodynamics Montelukast causes inhibition of airway cysteinyl leukotriene receptors as demonstrated by the ability to inhibit bronchoconstriction due to inhaled LTD 4 in asthmatics. Doses as low as 5 mg cause substantial blockage of LTD 4 -induced bronchoconstriction. In a placebo-controlled, crossover study (n=12), montelukast sodium inhibited early- and late-phase bronchoconstriction due to antigen challenge by 75% and 57%, respectively.

The effect of montelukast sodium on eosinophils in the peripheral blood was examined in clinical trials. In patients with asthma aged 2 years and older who received montelukast, a decrease in mean peripheral blood eosinophil counts ranging from 9% to 15% was noted, compared with placebo, over the double-blind treatment periods. In patients with seasonal allergic rhinitis aged 15 years and older who received montelukast sodium, a mean increase of 0.2% in peripheral blood eosinophil counts was noted, compared with a mean increase of 12.5% in placebo-treated patients, over the double-blind treatment periods; this reflects a mean difference of 12.3% in favor of montelukast sodium.

The relationship between these observations and the clinical benefits of montelukast noted in the clinical trials is not known [see Clinical Studies ( 14 )].

12.3Pharmacokinetics Absorption Montelukast is rapidly absorbed following oral administration. After administration of the 10-mg film-coated tablet to fasted adults, the mean peak montelukast plasma concentration (C max ) is achieved in 3 to 4 hours (T max ). The mean oral bioavailability is 64%.

The oral bioavailability and C max are not influenced by a standard meal in the morning. The safety and effectiveness of montelukast sodium in patients with asthma were demonstrated in clinical trials in which the 10-mg film-coated tablet formulation was administered in the evening without regard to the time of food ingestion. The safety and effectiveness of montelukast sodium in patients with seasonal allergic rhinitis were demonstrated in clinical trials in which the 10-mg film-coated tablet was administered in the morning or evening without regard to the time of food ingestion.

The comparative pharmacokinetics of montelukast when administered as two 5-mg chewable tablets versus one 10-mg film-coated tablet have not been evaluated. Distribution Montelukast is more than 99% bound to plasma proteins. The steady state volume of distribution of montelukast averages 8 to 11 liters.

Orally administered montelukast distributes into the brain in rats. Elimination The plasma clearance of montelukast averages 45 mL/min in healthy adults. Following an oral dose of radiolabeled montelukast, 86% of the rad…
