Why two NDCs? The FDA registers this code as 43538-176-45 — 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 → 43538-0176-45. Same drug, same package — only the format differs.

7 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.

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 43538-0176-45, 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

💵 About the dollar figures: “reimbursed” is what Medicaid paid pharmacies before confidential manufacturer rebates, so the program’s real net cost is lower than these numbers.

📊 Medicare Part D spend CMS · PART D · 2025 (Q1-Q4)

Medicare Part D (outpatient prescription) spending for Neuac — the program that covers self-administered drugs. 1 manufacturer.
⚠️ 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 Neuac. 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 43538-176-45, 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: 43538-0176-45, written without dashes as 43538017645. 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 43538-0176-45, the first segment (43538) is the labeler code FDA assigned to Medimetriks Pharmaceuticals; the middle segment (0176) identifies this specific product — its ingredient, strength, and dosage form; and the last segment (45) 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 Medimetriks Pharmaceuticals. Listing status can change — the directory data on this page refreshes weekly.
Who lists this product with the FDA?
Medimetriks 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.

4.2Colitis/Enteritis Neuac ® (clindamycin phosphate and benzoyl peroxide) Gel, 1.2%/5% is contraindicated in those individuals with a history of regional enteritis, ulcerative colitis, pseudomembranous colitis, or antibiotic-associated colitis [ see Warnings and Precautions (5.1) ].

⚠️ Warnings and Cautions ~1 min read

5 WARNINGS AND PRECAUTIONS Colitis: Clindamycin can cause severe colitis, which may result in death. Diarrhea, bloody diarrhea, and colitis (including pseudomembranous colitis) have been reported with the use of clindamycin. Neuac ® (clindamycin phosphate and benzoyl peroxide) Gel, 1.2%/5% should be discontinued if significant diarrhea occurs.

( 5.1 ) Ultraviolet light and environmental exposure (including use of tanning beds or sun lamps): Minimize sun exposure following drug application. ( 5.2 )

5.1Colitis Systemic absorption of clindamycin has been demonstrated following topical use of clindamycin. Diarrhea, bloody diarrhea, and colitis (including pseudomembranous colitis) have been reported with the use of topical and systemic clindamycin. If significant diarrhea occurs, Neuac ® (clindamycin phosphate and benzoyl peroxide) Gel, 1.2%/5% should be discontinued.

Severe colitis has occurred following oral and parenteral administration of clindamycin with an onset of up to several weeks following cessation of therapy. Antiperistaltic agents such as opiates and diphenoxylate with atropine may prolong and/or worsen severe colitis. Severe colitis may result in death.

Studies indicate a toxin(s) produced by Clostridia is one primary cause of antibiotic-associated colitis. The colitis is usually characterized by severe persistent diarrhea and severe abdominal cramps and may be associated with the passage of blood and mucus. Stool cultures for Clostridium difficile and stool assay for C. difficile toxin may be helpful diagnostically.

5.2Ultraviolet Light and Environmental Exposure Benzoyl peroxide, a component of Neuac ® (clindamycin phosphate and benzoyl peroxide) Gel, 1.2%/5%, may cause increased sensitivity to sunlight. Minimize sun exposure (including use of tanning beds or sun lamps) following drug application. [ See Nonclinical Toxicology (13.1) ] Patients who may be required to have considerable sun exposure due to occupation and those with inherent sensitivity to the sun should exercise particular caution.

🤒 Adverse Reactions ~2 min read

6 ADVERSE REACTIONS The following adverse reaction is described in more detail in the Warnings and Precautions section of the label: Colitis [ see Warnings and Precautions (5.1) ]. The most common local adverse reactions (≥5%) are erythema, peeling, dryness, and burning. ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact Medimetriks Pharmaceuticals, Inc. at 973-882-7512 or the 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 with rates in the clinical trials of another drug and may not reflect the rates observed in practice. During clinical trials, 397 subjects used clindamycin phosphate and benzoyl peroxide gel, 1.2%/5% once daily for 11 weeks for the treatment of moderate to moderately severe facial acne vulgaris. All subjects were graded for facial local skin reactions (erythema, peeling, burning, and dryness) on the following scale: 0 = absent, 1 = mild, 2 = moderate, and 3 = severe.

The percentage of subjects that had symptoms present before treatment (at baseline) and during treatment is presented in Table 1. Table 1. Local Skin Reactions With Use Of Clindamycin Phosphate and Benzoyl Peroxide Gel, 1.2%/5% Combined Results From Five Trials (n=397) % of Subjects Using Clindamycin Phosphate and Benzoyl Peroxide Gel, 1.2%/5% with Symptom Present Before Treatment (Baseline) During Treatment Symptom Mild Moderate Severe Mild Moderate Severe Erythema 28% 3% 0 26% 5% 0 Peeling 6% <1% 0 17% 2% 0 Burning 3% <1% 0 5% <1% 0 Dryness 6% <1% 0 15% 1% 0 (Percentages derived by number of subjects receiving clindamycin phosphate and benzoyl peroxide gel, 1.2%/5% with symptom score/number of enrolled subjects receiving clindamycin phosphate and benzoyl peroxide gel, 1.2%/5%).

6.2Postmarketing Experience The following adverse reactions have been identified during post approval use of clindamycin phosphate and benzoyl peroxide gel, 1.2%/5%. 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. Anaphylaxis, as well as allergic reactions leading to hospitalization, has been reported in postmarketing use with clindamycin phosphate and benzoyl peroxide gel, 1.2%/5%.

Urticaria, application site reactions, including discoloration have been reported.

🔄 Drug Interactions 197 words

7 DRUG INTERACTIONS Neuac ® (clindamycin phosphate and benzoyl peroxide) Gel, 1.2%/5% should not be used in combination with erythromycin-containing products because of its clindamycin component. ( 7.1 )

7.1Erythromycin Avoid using Neuac ® (clindamycin phosphate and benzoyl peroxide) Gel, 1.2%/5% in combination with erythromycin-containing products due to its clindamycin component. In vitro studies have shown antagonism between erythromycin and clindamycin. The clinical significance of this in vitro antagonism is not known.

7.2Concomitant Topical Medications Concomitant topical acne therapies should be used with caution since a possible cumulative irritancy effect may occur, especially with the use of peeling, desquamating, or abrasive agents. If irritancy or dermatitis occurs, reduce frequency of application or temporarily interrupt treatment and resume once the irritation subsides. Treatment should be discontinued if the irritation persists.

7.3Neuromuscular Blocking Agents Clindamycin has been shown to have neuromuscular blocking properties that may enhance the action of other neuromuscular blocking agents. Neuac ® (clindamycin phosphate and benzoyl peroxide) Gel, 1.2%/5% should be used with caution in patients receiving such agents.

7.4Topical Sulfone Products Use of topical benzoyl-peroxide-containing preparations with topical sulfone products may cause skin and facial hair to temporarily change color (yellow/orange).

👥 Use in Specific Populations ~1 min read

12 CLINICAL PHARMACOLOGY

12.1Mechanism of Action Clindamycin: Clindamycin is a lincosamide antibacterial [ see Clinical Pharmacology (12.4) ]. Benzoyl Peroxide: Benzoyl peroxide is an oxidizing agent with bacteriocidal and keratolytic effects, but the precise mechanism of action is unknown.

12.3Pharmacokinetics A comparative trial of the pharmacokinetics of clindamycin phosphate and benzoyl peroxide gel, 1.2%/5% and 1% clindamycin solution alone in 78 subjects indicated that mean plasma clindamycin levels during the 4-week dosing period were less than 0.5 ng/mL for both treatment groups. Benzoyl peroxide has been shown to be absorbed by the skin where it is converted to benzoic acid. Less than 2% of the dose enters systemic circulation as benzoic acid.

12.4Microbiology Clindamycin binds to the 50S ribosomal subunits of susceptible bacteria and prevents elongation of peptide chains by interfering with peptidyl transfer, thereby suppressing protein synthesis. In Vivo Activity: No microbiology studies were conducted in the clinical trials with this product. In Vitro Activity: The clindamycin and benzoyl peroxide components individually have been shown to have in vitro activity against Propionibacterium acnes , an organism which has been associated with acne vulgaris; however, the clinical significance of this in vitro activity is not known.

Drug Resistance: There are reports of an increase of P. acnes resistance to clindamycin in the treatment of acne. In patients with P. acnes resistant to clindamycin, the clindamycin component may provide no additional benefit beyond benzoyl peroxide alone.
