Why two NDCs? The FDA registers this code as 25021-840-05 — 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 → 25021-0840-05. Same drug, same package — only the format differs.

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.

ℹ️
No price is published for this exact package yet. CMS surveys NADAC per package size, so a different pack of the same drug often has one.
Where does this data come from?
NADAC (National Average Drug Acquisition Cost) is the CMS weekly pharmacy-acquisition-cost survey — what pharmacies pay. ASP (Average Sales Price) is the CMS Medicare Part B drug-payment file, published quarterly. Medicaid pays is computed by us from CMS State Drug Utilization Data (total reimbursed ÷ units, trailing 12 months) — gross of rebates and inclusive of dispensing fees, so it reflects what Medicaid paid, not an acquisition cost. Medicare drug plans pay is the median negotiated point-of-sale unit cost across plans listing this NDC in the CMS quarterly Prescription Drug Plan pricing files, before rebates. The VA pays is the federal contract price (FSS, and the statutory Big 4 ceiling where listed) from the VA National Acquisition Center pharmaceutical price file. All are free public government data; each measures a different payer, so the figures are not directly comparable.

🔒No FDA-approved generic found

We did not find an FDA-approved generic match for this exact strength, form and route. Patent/protection dates below may affect future generic timing.

🛡️ Latest patent/protection date listed: FDA patent/protection data lists protections through Dec 2037. This may affect when a full generic version becomes widely available, but it is not a guaranteed launch date.
📅 FDA approved Jul 8, 2022 RLD RS ⏳ ~11.2 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.

When could a generic Bludigo arrive?

Our estimate: 2032 to 2033 a wide window

How sure: Probable. More likely than not, but it can still move.

Why then: The patent fight is likely to end in an agreement that sets the launch. The terms are not public yet.

That is before the December 2037 date above, which is common: a court ruling or a deal with the brand’s maker often lets a generic in before the last patent runs out.

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 BLUDIGO 40 MG/5 ML AMPULE?
No FDA-approved generic equivalent is currently listed in the FDA Orange Book for BLUDIGO 40 MG/5 ML AMPULE. Based on the patents and exclusivity currently listed, the Orange Book estimate is that full-label generic entry may be delayed until Dec 2037 — an estimate, not a guaranteed launch date. We expect the first generic Bludigo between 2032 and 2033. See the forecast.
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.

( 5.3 )

5.1Cardiovascular Reactions Severe or life-threatening cardiovascular reactions including cardiac arrest, arrhythmia, asystole, second degree atrioventricular block, hypotension, elevation in blood pressure, bradycardia, and tachycardia have been reported generally within 60 minutes following administration of indigotindisulfonate sodium injection products and required urgent intervention [see Adverse Reactions ( 6.2 )] . Indigotindisulfonate may cause vasoconstriction by interference with vasodilation mediated by nitric oxide dependent mechanisms and by direct vasoconstriction.

Indigotindisulfonate may also cause hypotension. Patients with hypertension, heart rate and conduction disorders, or medications causing bradycardia may be at increased risk for elevated blood pressure, hypotension, and bradycardia. Closely monitor blood pressure and cardiac rhythm during and following the injection of BLUDIGO.

Interrupt administration if reactions are observed.

5.2Hypersensitivity Reactions Serious anaphylactic reactions with hypotension, dyspnea, bronchospasm, urticaria, or erythema have been reported with the use of indigotindisulfonate sodium injection products [see Adverse Reactions ( 6.2 )] . BLUDIGO is contraindicated in patients with known hypersensitivity to indigotindisulfonate [see Contraindications ( 4 )]. Monitor patients for anaphylactic reactions and have emergency equipment and trained personnel readily available.

5.3Interference with Oximetry Measurements Indigotindisulfonate has been reported to interfere with light absorption and transiently interfere with pulse oximetric methods. Anesthesiologists should be aware of the potential for artifactual reduction in SpO 2 when anesthetized patients are administered BLUDIGO.

🤒 Adverse Reactions ~2 min read ▾

6 ADVERSE REACTIONS Clinically significant adverse reactions are described elsewhere in the labeling: Cardiovascular Reactions [see Warnings and Precautions ( 5.1 )] Hypersensitivity Reactions [see Warnings and Precautions ( 5.2 )] Adverse reactions (≥ 1%) are constipation, nausea, vomiting, abdominal pain, pyrexia, ALT increase, and dysuria. ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact Sagent Pharmaceuticals at 1–800-625-1618 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 BLUDIGO was evaluated in a randomized, intra-patient controlled, blind to dose of BLUDIGO, clinical trial. A total of 118 adult patients undergoing endoscopic urological or gynecological procedures were treated intravenously; 58 (49%) of these patients received one dose of BLUDIGO 2.5 mL and 60 (51%) of patients received one dose of BLUDIGO 5 mL.

The 2.5 mL dose is not approved [see Dosage and Administration ( 2.1 )]. The mean age of patients was 51 years and 35 (30%) patients were 65 years of age or older. The majority of patients were White 105 (89%) and female 87 (74%).

The adverse reactions (≥1%) reported in the clinical trial are provided in Table 1 . Table 1. Adverse Reactions Reported at ≥ 1% of Patients Receiving BLUDIGO 5 mL Intravenously BLUDIGO 5 mL (N=60) n (%) Constipation 3 (5.0) Nausea 2 (3.3) Vomiting 2 (3.3) Abdominal Pain 2 (3.3) Pyrexia 2 (3.3) ALT increase 2 (3.3) Dysuria 1 (1.7)

6.2Postmarketing Experience The following adverse reactions have been identified following the use of indigotindisulfonate sodium injection products. 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. Cardiovascular disorders: cardiac arrest, arrhythmia, asystole, atrioventricular block second degree, hypotension, elevation in blood pressure, bradycardia, tachycardia General disorders and administration site conditions: injection site discoloration Immune system disorders: anaphylactic reactions with hypotension, dyspnea, bronchospasm, urticaria, erythema

👥 Use in Specific Populations ~2 min read ▾

8 USE IN SPECIFIC POPULATIONS Renal Impairment: BLUDIGO is not recommended for use in patients with eGFR<30 mL/min. ( 8.6 )

8.1Pregnancy Risk Summary Available data from case reports, case series, observational studies and clinical experience with indigotindisulfonate sodium injection use in pregnant women over several decades have not identified a drug associated risk of adverse maternal and fetal adverse effects. Indigotindisulfonate sodium injection use during the first trimester of pregnancy is rare; thus, the data are insufficient to evaluate for a drug associated risk of major birth defects and miscarriage. The majority of the published data were from intra-amniotic injections.

Animal reproduction studies using the intravenous route of administration have not been conducted. Oral administration of indigotindisulfonate sodium to pregnant rats and rabbits produced no evidence of fetal harm. However, oral availability is low (3%) so that the risk of intravenous administration of indigotindisulfonate sodium during pregnancy cannot be evaluated from the data available .

The estimated 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 estimated 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 It is not known if indigotindisulfonate is present in animal or human milk. The transfer of indigotindisulfonate into breastmilk is likely to be low and adverse effects on the breastfed infant are not expected [see Clinical Pharmacology ( 12.3 )]. There are no data on the effect of indigotindisulfonate on the breastfed infant or milk production.

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

8.4Pediatric Use The safety and effectiveness of BLUDIGO have not been established in pediatric patients.

8.5Geriatric Use Of the total number of subjects in the clinical study of BLUDIGO, 23 (20%) were 65 to 74 years of age, and 12 (10%) were 75 and older. 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.

8.6Renal Impairment Indigotindisulfonate is known to be excreted by the kidney through tubular secretion. No dedicated pharmacokinetic study using BLUDIGO in patients with varying degree of renal impairment has been conducted. Based on subgroup analyses in the randomized clinical trial, dose adjustment is not needed in patients with mild to moderate renal impairment (estimated glomerular filtration rate (eGFR) 30 to 89 mL/min derived from the Modification of Diet in Renal Disease formula).

BLUDIGO has not been studied in patients with eGFR <30 mL/min and is not recommended for use in these patients.

12.2Pharmacodynamics The blue color is detectable at the ureteral orifices within 4 minutes to 9 minutes after the intravenous injection.

🔬 Clinical Studies ~2 min read ▾

14 CLINICAL STUDIES The safety and efficacy of BLUDIGO were evaluated in a randomized intra-patient controlled, blind to dose of BLUDIGO, multi-center study (NCT04228445) in 118 adult patients undergoing endoscopic urological or gynecological surgical procedures including cystoscopic (58%), robotic (28%), and transvaginal (14%) approaches. The majority of patients were white (89%), female (74%), and younger than 65 years of age (70%). Mean age was 51 years, and age ranged from 20 to 88 years.

Patients were randomized in a 1:1 ratio to receive 2.5 mL or 5 mL of BLUDIGO intravenously prior to the end of the surgical procedure. Each patient underwent cystoscopy and received 5 mL of sodium chloride injection 0.9% followed by the randomized BLUDIGO dose for visualization of urinary flow from the ureteral orifices. The 2.5 mL dose is not approved [see Dosage and Administration ( 2.1 )] .

The ureteral orifices and urine flow were observed and video recorded from 0 to 10 minutes post injection, with separate recordings made following sodium chloride injection and BLUDIGO. The conspicuity of the urine flow from the ureteral orifices was assessed in a randomized, blinded fashion by two independent central reviewers using a 5-point scale (1 = no urine flow observed; 2 = weak urine flow, little color contrast; 3 = Color contrast or significant urine flow; 4 = strong urine flow with good color contrast; and 5 = strong urine flow with striking contrast in color) once after sodium chloride injection and twice after BLUDIGO resulting in paired data.

The surgeons also reviewed and scored conspicuity of the urine flow from the ureteral orifices. The responder for a ureter is defined as the difference in conspicuity score between BLUDIGO and sodium chloride injection being at least one point difference and the conspicuity score following BLUDIGO alone being greater than or equal to three. The reviewer agreement with the responder endpoint is acceptable.

The proportion of responders along with its 95% confidence interval by ureter and reviewer or surgeon is summarized in Table 3 . Table 3.

13 NONCLINICAL TOXICOLOGY

13.1Carcinogenesis, Mutagenesis, Impairment of Fertility Carcinogenicity Carcinogenicity studies in animals have not been conducted with indigotindisulfonate sodium using the intravenous route of administration. Long-term studies in mice with oral and subcutaneous administration of indigotindisulfonate sodium revealed no carcinogenic effects. Mutagenesis Although indigotindisulfonate sodium has been evaluated in a number of Ames assay studies, an Ames assay study that follows all currently recommended guidelines has not been performed.

Indigotindisulfonate was not genotoxic in all those Ames assays. The mutagenicity of indigotindisulfonate was inconclusive in the in vitro mouse L5187Y Lymphoma TK +/- assay. Orally administered indigotindisulfonate was not mutagenic in the in vivo mouse micronucleus test.

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