Why two NDCs? The FDA registers this code as 50402-100-13 — a 5-3-2 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 product segment → 50402-0100-13. 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.

A current SPL was checked, but it does not contain a structured or narrative inactive-ingredient list for this product. This does not mean the product has no inactive ingredients.
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.

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.
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 50402-100-13, 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: 50402-0100-13, written without dashes as 50402010013. 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 50402-0100-13, the first segment (50402) is the labeler code FDA assigned to Meridian Bioscience Israel Ltd; the middle segment (0100) identifies this specific product — its ingredient, strength, and dosage form; and the last segment (13) identifies this exact package size and type. Together they name one specific package of one specific product.
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 Meridian Bioscience Israel Ltd. Listing status can change — the directory data on this page refreshes weekly.
Does this product come in other package sizes?
Yes — the FDA directory lists 1 other package presentation of this same product, including 1 solution (50402-0100-14). Each has its own NDC and its own page — see the package list near the top of this page.
Who lists this product with the FDA?
Meridian Bioscience Israel Ltd 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?

6 ADVERSE REACTIONS The following clinically significant adverse reactions are discussed in the Warning and Precautions section of the labeling: Hypersensitivity Reactions [see Warning and Precautions ( 5.1 )] Adult Patients: The most common adverse reactions (incidence >0.3%) using the IDkit Hp included nausea, throat burning, and lightheadedness. ( 6.1 ) Pediatric Patients: The most common adverse reactions (incidence >1.5%) using the IDkit Hp included vomiting. ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact Meridian Bioscience Corporation at 1-800-543-1980 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. Clinical Trials Experience and Adverse Reactions in Adult Patients The safety of the IDkit Hp was evaluated in 465 adult patients who participated in two clinical trials (Trial 1 and Trial 2). All patients used the IDkit Hp Two kit for initial diagnosis and post-treatment monitoring of H. pylori infection.

The most commonly observed adverse reactions associated with the use of the IDkit Hp were nausea (0.6%), throat burning (0.4%), and lightheadedness (0.4%). Clinical Trials Experience and Adverse Reactions in Pediatric Patients The safety of the IDkit Hp was evaluated in one multi-center, non-randomized, open-label study (Trial 3). A total of 53 pediatric patients, 3 to less than 18 years of age, were enrolled in the study and used the IDkit Hp Two.

The only adverse reaction reported was vomiting (2%).

6.2Post-marketing Experience In addition to adverse reactions reported from clinical trials, the following adverse reactions have been identified during post-marketing use of the IDkit Hp One and IDkit Hp Two based on patient and test administrator reports. Because these reactions are reported voluntarily from a population of unknown size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure. Gastrointestinal: Nausea, vomiting, abdominal pain, diarrhea General: Sweating, throat pain, malaise Immune: Anaphylactic reaction Neurologic: Dizziness, headache

👥 Use in Specific Populations ~3 min read

8 USE IN SPECIFIC POPULATIONS Pediatric Use: The safety and effectiveness of IDkit Hp One and IDkit Hp Two has not been established in pediatric patients less than 3 years of age. ( 8.4 )

8.1Pregnancy Risk Summary Published data from other single oral dose 13 C-urea breath test kits containing urea and citric acid have not demonstrated a drug-associated risk of major birth defects, miscarriage or other adverse maternal or fetal outcomes. There are no available data on the use of IDkit Hp One or IDkit Hp Two use in pregnant women to evaluate for a drug-associated risk of major birth defects, miscarriage or other adverse maternal or fetal outcomes. There are no animal data that meet current standards for nonclinical developmental toxicity studies.

Based on available literature, no significant developmental or reproductive toxicities were observed in nonclinical studies with urea or citric acid. A single oral dose of 13 C-urea and citric acid at the maximum recommended human dose (MRHD) are unlikely to pose a significant developmental or reproductive risk, since humans typically have higher circulating levels of urea, and citric acid exposure from the test is within the range of normal dietary intake. The background risk of major birth defects and miscarriage for the indicated population is unknown.

All pregnancies have a background risk of birth defects, loss, or other adverse outcomes. In the U.S. general population, the background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2% to 4% and 15% to 20%, respectively.

8.2Lactation Risk Summary There are no data on the presence of the components of IDkit Hp One or IDkit Hp Two in either human or animal milk, the effects on the breastfed infant, or the effects on milk production. A single oral dose of 13 C-urea and citric acid at the MRHD is unlikely to pose a risk in breastfed infants since humans typically have higher circulating levels of urea, and citric acid exposure from the test is within the range of normal dietary intake. The developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for IDkit Hp One or IDkit Hp Two and any potential adverse effects on the breastfed infant from IDkit Hp One or IDkit Hp Two or from the underlying maternal condition.

8.4Pediatric Use The safety and effectiveness of IDkit Hp One and IDkit Hp Two have been established in pediatric patients 3 years of age and older. Use of IDkit Hp One and IDkit Hp Two in pediatric patients is supported by two trials demonstrating clinical performance in adults along with a multi-center, non-randomized, open label study confirming the safety of the 13 C-urea substrate and the performance of the BreathID system device in pediatric patients [see Adverse Reaction ( 6.1 ) and Clinical Studies ( 14.1 )] .

The safety and effectiveness of IDkit Hp One and IDkit Hp Two have not been established in pediatric patients less than 3 years of age.

8.5Geriatric Use Of the total number of IDkit Hp One and IDkit Hp Two patients in clinical studies for detection of H. pylori , 74 (12%) were 65 to 74 years of age, and 38 (6%) were 75 years of age and older [see Clinical Studies ( 14 )] . No overall differences in safety or effectiveness were observed between patients 65 years of age and older and younger adult patients, and other reported clinical experience has not identified differences in responses between the elderly and younger adult patients.

8.6Gastrectomy Data is insufficient for recommending the use of IDkit Hp One and IDkit Hp Two on patients with total or partial gastrectomy [see Clinical Pharmacology ( 12.3 )] .

12 CLINICAL PHARMACOLOGY

12.1Mechanism of Action IDkit Hp One and IDkit Hp Two are administered using the BreathID system device, a non-invasive breath test that analyzes a breath sample before and after ingestion of 13 C- urea and citric acid. 75 mg 13 C-urea and 4. g citric acid is dissolved in water and administered orally to the patient. The presence of citric acid creates an acidic environment in the stomach and delays the gastric emptying of the ingested solution to the duodenum.

These two characteristics facilitate the decomposition of the urea by H. pylori , if present. Thus, in the presence of urease produced by gastric H. pylori , 13 C-urea is decomposed to 13 CO 2 and NH 3 according to the following equation: The 13 CO 2 formed is absorbed into the blood and then exhaled in breath, enabling detection of elevated 13 CO 2 in H. pylori-positive patients. In H. pylori-negative patients, no significant production of 13 CO 2 occurs in the stomach, as there are no human enzymes capable of hydrolyzing urea under gastric conditions. equ2

12.2Pharmacodynamics IDkit Hp One and IDkit Hp Two ( 13 C-urea and citric acid) have no therapeutic pharmacodynamic effects. It contains diagnostic agents 13 C-urea and citric acid that detects the presence of H. pylori based on bacterial urease activity in the gastric mucosa.

12.3Pharmacokinetics Absorption Following oral administration of 13 C-urea 100 mg to 400 mg (1.33 to 4 times the highest approved recommended dosage) in 3 healthy subjects, the Tmax of 13 C-urea was around 30 minutes [see Dosage and Administration ( 2.1 )] . Elimination Metabolism In H. pylori -positive subjects, 13 C-urea is hydrolysed in the stomach by bacterial urease to 13 CO 2 and ammonia. Excretion Urea is eliminated predominantly by renal excretion.

Specific Populations The pharmacokinetics of 13 C-urea are not expected to have clinically meaningful differences based on age (including geriatric and pediatric patients), sex, race, or ethnicity with respect to its activity as diagnostic agent. Gastrectomy Patients The performance and reliability of the test in gastrectomy patients have not been established. Drug Interaction Studies No formal drug interaction studies have been conducted.

Antimicrobials, proton pump inhibitors, and bismuth preparations may affect H. pylori status or urease activity and interfere with test results [see Drug Interactions ( 7 )] . In vitro studies demonstrated that mouthwash, chewing gum, carbonated beverages, cigarette smoke, acetone, and alcohol had no clinically relevant effect on test results.
