Why two NDCs?
The FDA registers this code as 0264-2304-00 — 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 → 00264-2304-00. Same drug, same package — only the format differs.

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.

🗺️ 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 00264-2304-00, 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.
📅 Q1 2025 – Q4 2025 · 4 quarters of data
ⓘ The newest quarter is usually incomplete when first published; states restate recent quarters in later CMS releases, so the latest figures typically revise upward. State coverage-policy changes can also shift quarter-to-quarter totals.

💊 Medicaid utilization by pack size
Medicaid (SDUD) totals over the four most recent reported quarters for every package size of this drug — handy when a specific package (e.g. a starter/titration pack) carries little or no Medicaid volume on its own.

📊 Medicare Part D spend CMS · PART D · 2026 (Q1)
Medicare Part D (outpatient prescription) spending for Acetic Acid — the program that covers self-administered drugs. 3 manufacturers.
⚠️ 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 Acetic Acid. 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 FDA registers it as 0264-2304-00, 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: 00264-2304-00, written without dashes as 00264230400. 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 00264-2304-00, the first segment (00264) is the labeler code FDA assigned to B. Braun Medical Inc.; the middle segment (2304) identifies this specific product — its ingredient, strength, and dosage form; and the last segment (00) 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 B. Braun Medical Inc.. 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 500 ml (00264-2304-10). 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?
B. Braun Medical 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.
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?

📄 Full prescribing information FDA SPL
The complete FDA label for this product — the official prescribing information, verbatim, section by section. Jump with a chip, search within the label, or expand everything.
INDICATIONS AND USAGE 0.25% Acetic Acid Irrigation USP is indicated as a constant or intermittent bladder rinse to help prevent the growth and proliferation of susceptible urinary pathogens (especially ammonia-forming bacteria) in the management of patients who require prolonged placement of an indwelling urethral catheter. It also may be used for periodic irrigation of an indwelling catheter to help maintain patency by reducing the formation of calcium encrustations.
⏱️Dosage and Administration164 words▾
DOSAGE AND ADMINISTRATION As required for urologic irrigation. 0.25% Acetic Acid Irrigation USP may be administered by gravity drip via an administration set connected to an indwelling urethral catheter designed for continuous or intermittent two-way flow. For continuous or intermittent irrigation, the rate of administration will correspond roughly to the rate of urine flow and should be adjusted to maintain a urinary effluent pH of 4.5 to 5.0.
Nitrazine or other pH paper may be used to monitor pH, preferably at least four times daily. Drip rate should be adjusted as necessary to maintain desired pH; increasing flow rate reduces pH value and vice versa. With continuous or intermittent irrigation, each patient will require a volume of approximately 500 to 1500 mL per 24 hours.
Some additives may be incompatible. Consult with pharmacist. When introducing additives, use aseptic techniques.
Mix thoroughly. Do not store. This drug product should be inspected visually for particulate matter and discoloration prior to administration, whenever solution and container permit.
⛔Contraindications20 words▾
CONTRAINDICATIONS 0.25% Acetic Acid Irrigation USP is not for injection. This solution is contraindicated for irrigation during transurethral surgical procedures.
⚠️Warnings81 words▾
WARNINGS FOR UROLOGIC IRRIGATION ONLY. NOT FOR INJECTION. Use of this solution in patients with mucosal lesions of the urinary bladder may be harmful due to irritation of the lesion.
Absorption via open lesions of the bladder mucosa may result in systemic acidosis. Do not warm above 150°F (66°C). After opening container, the contents should be used promptly in order to minimize the possibility of bacterial growth or pyrogen formation.
Discard unused portion of irrigating solution since it contains no preservative.
🤒Adverse Reactions51 words▾
ADVERSE REACTIONS Systemic acidosis, pain, and hematuria have been reported in patients receiving urinary bladder irrigation with 0.25% acetic acid solution. If an adverse reaction does occur, discontinue administration of the irrigant, evaluate the patient, institute appropriate therapeutic countermeasures, and save the remainder of the fluid for examination, if deemed necessary.
🤰Pregnancy58 words▾
Pregnancy Teratogenic Effects Animal reproduction studies have not been conducted with 0.25% Acetic Acid Irrigation USP. It is also not known whether 0.25% Acetic Acid Irrigation USP can cause fetal harm when administered to a pregnant woman or can affect reproduction capacity. 0.25% Acetic Acid Irrigation USP should be given to a pregnant woman only if clearly needed.
🧒Pediatric Use12 words▾
Pediatric Use Safety and effectiveness in pediatric patients have not been established.
🧓Geriatric Use46 words▾
Geriatric Use Clinical studies of 0.25% Acetic Acid Irrigation USP have not been performed to determine whether patients over 65 years of age respond differently from younger subjects. Although systemic absorption of the product is unlikely, greater sensitivity of some older individuals cannot be ruled out.
🆘Overdosage51 words▾
OVERDOSAGE Systemic absorption is unlikely unless there are open lesions of the bladder mucosa that have gone undetected. In such event, discontinue the irrigation, evaluate the patient for possible systemic acidosis, intravascular hemolysis, and circulatory overload and institute appropriate countermeasures as indicated. See WARNINGS , PRECAUTIONS , and ADVERSE REACTIONS .
🧬Clinical Pharmacology93 words▾
CLINICAL PHARMACOLOGY Irrigation of the urinary bladder with acetic acid solution in a concentration of 0.25% has been shown to exert an antimicrobial action against a variety of microorganisms (especially ammonia-forming bacteria) that frequently gain access to the urinary bladder in patients who require prolonged indwelling urethral catheterization. Its antimicrobial action is dependent on administration via the indwelling catheter at a sufficient rate (continuous or intermittent) to maintain an effluent pH of 5.0 or lower.
Maintenance of low pH of bladder urine also helps reduce formation of calcium encrustations in the indwelling catheter.
