  • RxCUI (RxNorm): 1117536
Why two NDCs? The FDA registers this code as 51662-1611-1 — a 5-4-1 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 package segment → 51662-1611-01. 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.
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.
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.

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 DailyMed — ingredient 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.

🎯 Indications and Usage ⏱️ Dosage and Administration ⛔ Contraindications ⚠️ Warnings and Cautions 📦 How Supplied / Storage and Handling 📦 Storage and Handling 📄 Package Label / Principal Display Panel
🎯 Indications and Usage 18 words ▾

INDICATIONS & USAGE INDICATIONS: For cauterization of skin or mucous membrane and for removing warts and granulated tissue.

⏱️ Dosage and Administration 129 words ▾

DOSAGE & ADMINISTRATION Moisten the applicator tip with distilled, deionized or purified water and apply the silver nitrate to the affected area by holding, rubbing, or rotating the tip along the affected tissue. The strength of the action is controlled by the dilution with distilled, deionized or purified water. One silver nitrate applicator is generally sufficient for each application.

The action of the silver nitrate can be stopped by washing the area with saline solution (0.9% sodium chloride). Using saline solution to wet the applicator tips, or residual saline from wound flushing/washing will interfere with the action of silver nitrate resulting in cauterization failure. Only use distilled, deionized or purified water to wet applicator tips.

Blot dry wounds that have been flushed/washed with saline prior to applying silver nitrate.

⛔ Contraindications 69 words ▾

CONTRAINDICATIONS Silver salts stain tissue black due to deposition of reduced silver. The stain gradually disappears within a period of two weeks. Prolonged ingestion or absorption of silver compounds leads to deposition of silver in connective tissues, producing a slate-blue discoloration of the skin known as argyria. This discoloration may also appear on mucous membranes such as the margins of gums. The sclera of the eye is also stained.

⚠️ Warnings and Cautions 177 words ▾

WARNINGS & PRECAUTIONS WARNING: KEEP OUT OF REACH OF CHILDREN. The active ingredients are poisonous and may be fatal when ingested in sufficient doses. The symptoms include toxic gastroenteritis, which may lead to coma, convulsion, paralysis and profound alteration of respiration.

If poisoning occurs, immediately consult a physician. WARNING: DO NOT USE ON THE EYES. In case of eye contact, hold eyes open and immediately flush thoroughly with water for at least 15 minutes and consult a physician.

CAUTION: SILVER NITRATE IS A CAUSTIC SUBSTANCE. Chemical burns may result from inappropriate use of product. • Wear chemical resistant gloves while using this product. Wear other appropriate personal protective equipment as needed. • Take care to confine the silver nitrate to the area being treated by using an appropriate physical or chemical barrier to prevent staining or burning of untreated tissue. • Skin contact time with applicators should be minimal when used on thin delicate skin or neonates. • Avoid prolonged contact with skin or other surfaces since staining may occur.

CAUTION: FEDERAL LAW PROHIBITS DISPENSING WITHOUT PRESCRIPTION.

About this NDC listing & data coverage

Finished prescription product Marketed without an FDA application

Listed without an FDA application

This product's marketing category indicates it is marketed without an approved FDA application (no NDA, ANDA, or BLA on file). Having an NDC does not by itself establish FDA approval — the NDC Directory is a listing system, not an approval decision. Approval-linked data such as Orange Book therapeutic-equivalence ratings therefore does not apply.

Questions about this listing

Is this NDC FDA-approved?
An NDC listing does not by itself establish FDA approval — the NDC Directory records that a product is listed with FDA, not that it was reviewed and approved. This listing's marketing category is "Unapproved Drug Other". Products approved under an application carry an NDA, ANDA, or BLA number.
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 HF Acquisition Co LLC, DBA HealthFirst. Listing status can change — the directory data on this page refreshes weekly.
Who lists this product with the FDA?
HF Acquisition Co LLC, DBA HealthFirst 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.
