Why two NDCs? The FDA registers this code as 0270-1412-15 — a 4-4-2 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 labeler segment → 00270-1412-15. Same drug, same package — only the format differs.

2 inactive ingredients listed in the exact product block matched to this NDC.

Where does this data come from?
Data sourced from official FDA Structured Product Labeling (SPL) via DailyMedingredient classCode="IACT" elements from the exact product block matched by this NDC. Label-section narrative from DailyMed / the openFDA label index is shown separately when available.

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 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.
Medicare Part B allowsASP · Q9967 $0.155 / Q9967 unit
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.

🔒Generic approved by FDA, but pharmacy availability is not confirmed

The FDA lists approved generic versions of this medicine, but that does not always mean a pharmacy can get one today. Patent rules, launch agreements, supply and pricing can affect when generics actually arrive.

🛡️ Latest patent/protection date listed: FDA patent/protection data lists protections through Oct 2028. This may affect when a full generic version becomes widely available, but it is not a guaranteed launch date.
📅 FDA approved Dec 31, 1985 AP TE-rated RLD RS ⏳ ~2.1 yr to latest listed protection

Why the date isn’t exact: Generic timing can change because patents may be challenged, settled, licensed, added, removed, or worked around with a narrower label — and FDA approval does not always mean a pharmacy can get the generic today.

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 ISOVUE-M 300 61% VIAL?
Yes — an FDA-approved generic equivalent is listed in the FDA Orange Book for ISOVUE-M 300 61% VIAL. See the alternatives section for substitutable, lower-cost products.
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.

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 0270-1412-15, 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: 00270-1412-15, written without dashes as 00270141215. 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 00270-1412-15, the first segment (00270) is the labeler code FDA assigned to Bracco Diagnostics Inc; the middle segment (1412) identifies this specific product — its ingredient, strength, and dosage form; and the last segment (15) 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 Bracco Diagnostics Inc. Listing status can change — the directory data on this page refreshes weekly.
Who lists this product with the FDA?
Bracco Diagnostics 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 Q9967 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?

⏱️ Dosage and Administration ~2 min read

2 DOSAGE AND ADMINISTRATION Individualize the volume and concentration of ISOVUE-M according to the specific dosing tables based on patient age, body weight, and study to be performed. ( 2.2 , 2.3 ) See full prescribing information for important dosage and administration information. ( 2.1 )

2.1Important Dosage and Administration Information ISOVUE-M is for intrathecal use only. Specific concentrations of ISOVUE-M are recommended for each type of imaging procedure [see Dosage and Administration ( 2.2 , 2.3 )]. Individualize the volume, concentration, and injection rate of ISOVUE-M according to the dosing tables [see Dosage and Administration ( 2.2 , 2.3 )].

Consider factors such as age, body weight, anticipated pathology and degree and extent of opacification required, structure(s) or area to be examined, concomitant medical conditions, and imaging equipment and technique to be employed. Hydrate patients prior to and following ISOVUE-M administration [see Warnings and Precautions ( 5.2) ] . Use aseptic technique for all handling and administration of ISOVUE-M.

ISOVUE-M may be administered at either body temperature (37°C, 98.6°F) or room temperature (20°C to 25°C, 68°F to 77°F). Visually inspect ISOVUE-M for particulate matter and discoloration prior to administration whenever the solution and container permit. Do not administer ISOVUE-M if particulate matter or discoloration are observed.

Do not mix ISOVUE-M with other drugs. ISOVUE-M is packaged in a single-dose vial and intended for one procedure only. Discard any unused portion.

2.2Recommended Dosage for Intrathecal Procedures in Adults The recommended doses in adults are shown in Table 1 . Administer over 1 minute to 2 minutes. Allow at least 48 hours before repeat administration to avoid overdose; however, whenever possible, 5 days to 7 days is recommended.

If CT myelography is performed, delay imaging by at least 4 hours to reduce the degree of contrast.

⚠️ Warnings and Cautions ~2 min read

5 WARNINGS AND PRECAUTIONS Hypersensitivity Reactions: Life-threatening or fatal reactions can occur. Always have emergency resuscitation equipment and trained personnel available. ( 5.1 ) Acute Kidney Injury: Acute injury including renal failure can occur.

Use the lowest dose and maintain adequate hydration to minimize risk. ( 5.2 ) Cardiovascular Adverse Reactions: Hemodynamic disturbances including shock and cardiac arrest may occur during or after ISOVUE-M administration. ( 5.4 ) Thyroid Dysfunction in Pediatric Patients 0 Years to 3 Years of Age: Individualize thyroid function monitoring based on risk factors such as prematurity.

( 5.6 )

5.1Hypersensitivity Reactions ISOVUE-M can cause life-threatening or fatal hypersensitivity reactions including anaphylaxis. Manifestations include respiratory arrest, laryngospasm, bronchospasm, angioedema, and shock [see Adverse Reactions ( 6.2 )] . Most severe reactions develop shortly after the start of injection (e.g., within 1 to 3 minutes), but delayed reactions can also occur.

There is increased risk of hypersensitivity reactions in patients with a history of previous reactions to contrast agents, and known allergic disorders (i.e., bronchial asthma, allergic rhinitis, and food allergies) or other hypersensitivities. Premedication with antihistamines or corticosteroids does not prevent serious life-threatening reactions, but may reduce their incidence and severity. Obtain a history of allergy or hypersensitivity reactions to iodinated contrast agents and always have emergency resuscitation equipment and trained personnel available prior to ISOVUE-M administration.

Monitor all patients for hypersensitivity reactions.

5.2Acute Kidney Injury Acute kidney injury, including renal failure, may occur after administration of iodinated contrast agents. Risk factors include pre-existing renal insufficiency, dehydration, diabetes mellitus, congestive heart failure, advanced vascular disease, elderly age, concomitant use of nephrotoxic or diuretic medications, multiple myeloma or other paraproteinemias, and repetitive or large doses of iodinated contrast agents. Use the lowest dose of ISOVUE-M, especially in patients with risk factors for acute kidney injury.

Adequately hydrate patients prior to and following ISOVUE-M administration .

5.3Increased Risk of Seizures Focal and generalized motor seizures have been reported after intrathecal use of iodinated contrast agents including ISOVUE-M. In several of the cases, higher than recommended doses were administered. Use of medications that may lower the seizure threshold (phenothiazine derivatives, including those used for their antihistaminic properties; tricyclic antidepressants; MAO inhibitors; CNS stimulants; analeptics; antipsychotic agents) should be carefully evaluated.

Consider discontinuing these agents at least 48 hours before and for at least 24 hours following intrathecal administration of ISOVUE-M.

5.4Cardiovascular Adverse Reactions Iodinated contrast agents increase the circulatory osmotic load and may induce acute or delayed hemodynamic disturbances in patients with congestive heart failure, severely impaired renal function, combined renal and hepatic disease, and combined renal and cardiac disease, particularly when repetitive or large doses are administered. Fatal cardiovascular reactions have occurred mostly within 10 minutes of injection of iodinated contrast agent by an intravascular route; the main feature was cardiac arrest with cardiovascular disease as the main underlying factor.

Hypotensive collapse and shock have occurred. The administration of iodinated contrast agent may cause pulmonary edema in patients with heart failure. Based upon published reports, deaths associated with the administration of iodinated contrast agents range from 6.6 per 1 million (0.00066 percent) to 1 in 10,000 patients (0.01 percent).

Use the lowest necessary dose of ISOVUE-M in patients with congestive heart failure and always have emergenc…

6 ADVERSE REACTIONS The following adverse reactions are described in greater detail in other sections: Hypersensitivity Reactions [see Warnings and Precautions ( 5.1 )] Acute Kidney Injury [see Warnings and Precautions ( 5.2 )] Increased Risk of Seizures [see Warnings and Precautions ( 5.3 )] Cardiovascular Adverse Reactions [see Warnings and Precautions ( 5.4 )] Thyroid Dysfunction in Pediatric Patients 0 to 3 Years of Age [see Warnings and Precautions ( 5.6 )] Severe Cutaneous Adverse Reactions [see Warnings and Precautions ( 5.9 )] Most common adverse reactions (incidence > 1%) are headache, nausea, vomiting, back pain, leg pain, neck pain, and hypotension.

( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact Bracco Diagnostics Inc. at 1-800-257-5181 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. The safety of ISOVUE-M was evaluated in 686 adult patients receiving ISOVUE-M intrathecally in clinical studies. Table 3 shows the common adverse reactions (>1%).

These reactions usually occur 1 to 10 hours after injection, almost all occurring within 24 hours. Table 3: Adverse Reactions Reported in >1% of Patients Receiving Intrathecal Injection of ISOVUE-M in Clinical Studies Adverse Reaction ISOVUE-M (N=686) % Headache

👥 Use in Specific Populations ~3 min read

8 USE IN SPECIFIC POPULATIONS Lactation: A lactating woman may pump and discard breast milk for 10 hours after ISOVUE-M administration. ( 8.2 )

8.1Pregnancy Risk Summary Available data from published literature and postmarketing cases from decades of use with iopamidol during pregnancy have not identified a drug-associated risk of major birth defects, miscarriage, or other adverse maternal or fetal outcomes. Iopamidol crosses the placenta and reaches fetal tissues in small amounts ( see Data ). In animal reproduction studies, no adverse developmental outcomes were observed with intravenous administration of iopamidol to pregnant rats and rabbits during organogenesis at doses up to 2.7 and 1.4 times, respectively, the maximum recommended human dose ( see Data ).

The 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 to 4% and 15 to 20%, respectively.

Data Human Data Literature reports show that intravenously administered iopamidol crosses the placenta and is visualized in the digestive tract of exposed infants after birth. Animal Data Iopamidol did not affect fetal development and did not induce teratogenic changes in the offspring in either rats or rabbits at the following dose levels tested: 600 mg, 1,500 mg, or 4,000 mg iodine/kg in rats, administered intravenously once a day during days 6 through 15 of pregnancy; 300 mg, 800 mg, or 2,000 mg iodine/kg in rabbits, administered intravenously once a day during days 6 through 18 of pregnancy.

8.2Lactation Risk Summary There are no data on the presence of iopamidol in human milk, the effects on the breastfed infant, or the effects on milk production. Iodinated contrast agents are present unchanged in human milk in very low amounts, with poor absorption from the gastrointestinal tract of a breastfed infant. The developmental and health benefits of breastfeeding should be considered along with the mother's clinical need for ISOVUE- M and any potential adverse effects on the breastfed infant from ISOVUE-M or from the underlying maternal condition.

Clinical Considerations Interruption of breastfeeding after exposure to iodinated contrast agents is not necessary because the potential exposure of the breastfed infant to iodine is small. However, a lactating woman may consider interrupting breastfeeding and pumping and discarding breast milk for 10 hours (approximately 5 half- lives) after ISOVUE-M administration in order to minimize drug exposure to a breastfed infant.

8.4Pediatric Use The safety and effectiveness of ISOVUE-M for lumbar and thoracic myelography and CT myelography have been established in pediatric patients aged 2 years and older. Pediatric patients at higher risk of experiencing adverse reactions during and after any iodinated contrast agent administration may include those having asthma, sensitivity to medication or allergens, cyanotic heart disease, congestive heart failure, or serum creatinine greater than 1.5 mg/dL. Thyroid function tests indicative of thyroid dysfunction, characterized by hypothyroidism or transient thyroid suppression have been reported following iodinated contrast agent administration in pediatric patients, including term and preterm neonates; Some patients were treated for hypothyroidism.

After exposure to iodinated contrast agent, individualize thyroid function monitoring in pediatric patients 0 to 3 years of age based on underlying risk factors, especially in term and preterm neonates [see Warnings and Precautions ( 5.6 ) and Adverse Reactions ( 6.2 )] . The safety and effectiveness of ISOVUE-M for lumbar and thoracic myelography and CT myelography have not been established in pediatric patients younger than 2 years of age. The safety and effectiveness of ISOVUE-M for…

🆘 Overdosage 59 words

10 OVERDOSAGE Doses above 3,000 mg iodine in adults and 2,400 mg iodine in pediatric patients aged 2 years and older may result in an increased frequency and severity of adverse reactions including seizures. Treatment of an overdose is directed toward the support of all vital functions and prompt institution of symptomatic therapy. Iopamidol can be removed by dialysis.

🧬 Clinical Pharmacology ~1 min read

12 CLINICAL PHARMACOLOGY

12.1Mechanism of Action Intrathecal administration of iopamidol opacifies the body structures where the contrast agent is present, permitting their radiographic visualization through attenuation of photons.

12.2Pharmacodynamics Following intrathecal injection, iopamidol provides diagnostic contrast for at least 30 minutes for conventional myelography. At about 1 hour, contrast will no longer be sufficient for conventional myelography. However, diagnostic contrast for CT myelography remains at least 6 hours after administration. The exposure-response relationships and time course of pharmacodynamic response of iopamidol have not been fully characterized.

12.3Pharmacokinetics Absorption Iopamidol is absorbed into the bloodstream from cerebrospinal fluid (CSF); following intrathecal administration, iopamidol appears in plasma within 1 hour and virtually all of the drug reaches the systemic circulation within 24 hours. Distribution Iopamidol did not bind to serum or plasma proteins at 1 hour after administration. Elimination The plasma half-life is approximately 2 hours; the half-life is not dose dependent .

Metabolism Iopamidol does not undergo significant metabolism, deiodination, or biotransformation. Excretion Iopamidol is excreted mainly through the kidneys following intrathecal administration, and the drug is essentially undetectable in the plasma 48 hours later. In patients with normal renal function, the cumulative urinary excretion for iopamidol, expressed as a percentage of administered intravenous dose is approximately 35% to 40% at 60 minutes, 80% to 90% at 8 hours, and 90% or more in the 72- to 96-hour period after administration.

In patients with normal renal function, approximately 1% or less of the administered dose appears in cumulative 72- to 96-hour fecal specimens.
