Why two NDCs? The FDA registers this code as 51662-1311-3 — 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 → 51662-1311-03. Same drug, same package — only the format differs.

4 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.

📊 Medicare Part D spend CMS · PART D · 2026 (Q1)

Medicare Part D (outpatient prescription) spending for Atropine Sulfate — the program that covers self-administered drugs. 7 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 Atropine Sulfate. 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.

💵 About the dollar figures: spending is what Part D plans paid before confidential manufacturer rebates, so the program’s real net cost is lower. A blank patient count means fewer than 11 people — CMS hides counts that small to protect privacy. Source: CMS Medicare Quarterly Part D Spending by Drug (data.cms.gov), updated quarterly.

🧭 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 FDA registers it as 51662-1311-3, 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: 51662-1311-03, written without dashes as 51662131103. 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 51662-1311-03, the first segment (51662) is the labeler code FDA assigned to HF Acquisition Co LLC, DBA HealthFirst; the middle segment (1311) identifies this specific product — its ingredient, strength, and dosage form; and the last segment (03) 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 HF Acquisition Co LLC, DBA HealthFirst. 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 20 ml (51662-1311-01). 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?
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.

🎯 Indications and Usage 109 words

INDICATIONS & USAGE Atropine sulfate is given parenterally as a preanesthetic medication to decrease salivation and bronchial secretions. It is useful in pylorospasm and other spastic conditions of the gastrointestinal tract. For ureteral and biliary colic, atropine sulfate given with morphine may be indicated.

Atropine sulfate is indicated for relaxation of the upper gastrointestinal tract and colon during hypotonic radiography. Atropine is used as an antidote for pilocarpine, physostigmine, isoflurophate, choline esters, certain species of aminata and in poisoning by the organic phosphate cholinesterase inhibitors found in certain insecticides and by chemical warfare “nerve gases”. Large doses relieve the muscarine-like symptoms and some of the central nervous system manifestations.

⏱️ Dosage and Administration 209 words

DOSAGE & ADMINISTRATION The usual dose of atropine sulfate is 0.4 to 0.6 mg. Suggested dosages for pediatric patients are as follows: 7 - 16 lbs. – 0.1 mg 40 - 65 lbs. – 0.3 mg 17 - 24 lbs. – 0.15 mg 65 - 90 lbs. – 0.4 mg 24 - 40 lbs. – 0.2 mg Over 90 lbs. – 0.4 to 0.6 mg Table of Dosage Equivalents These doses may be exceeded in certain cases. For hypotonic radiography of the gastrointestinal tract, the usual adult dose is 1 mg intramuscularly.

Adults suspected of contact with organic phosporous insecticides of the parathion type should be given atropine sulfate 0.8 mg intramuscularly. If an atropine effect is not apparent within 30 minutes or if definite symptoms of the poisoning occur (nausea, vomiting, diarrhea, pupillary constriction, pulmonary edema, fasciculations of eyelids and tongue, jerky ocular movements and excessive sweating, salivation and bronchial secretion), atropine sulfate 2 mg should be given intramuscularly at hourly intervals until signs of atropinization are observed.

Up to 2 or 3 times of this dose (4 to 6 mg) may be required in severe cases. Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration, whenever solution and container permit. DOSAGE

Contraindications 54 words

CONTRAINDICATIONS Conditions at which inhibition of postganglionic cholinergic nerves are undesirable, such as glaucoma and tachycardia. Also contraindicated in asthma, because the parenteral dose which might relieve asthma would have an excessive drying effect upon mucous plugs in the bronchi. Prostatic hypertrophy, while not a contraindication, requires special attention to signs of urinary retention.

⚠️ Warnings 109 words

WARNINGS Atropine is a highly potent drug and due care is essential to avoid overdosage, especially with intravenous administration. Pediatric populations are more susceptible than adults to the toxic effects of anticholinergic agents. Atropine I.V. decreased the rate of mexiletine absorption without altering the relative oral bioavailability; this delay in mexiletine absorption was reversed by the combination of atropine and intravenous metoclopramide during pretreatment for anesthesia.

Atropine is not removed by dialysis. This drug is effective in very low dosage and overdose may cause permanent damage or death, especially in children. This product contains Benzyl Alcohol which has been associated with a fatal gasping syndrome in infants and neonates.

🤒 Adverse Reactions 52 words

ADVERSE REACTIONS Individual tolerance varies greatly, but these systemic doses are likely to produce the following effects: A scarlatiniform rash may occur. Atropine may produce fever, particularly in children, through inhibition of heat loss by evaporation. Although large doses of atropine may cause an alarming condition, recovery is usual. ADVERSE EVENT TABEL

🆘 Overdosage 159 words

OVERDOSAGE Toxic doses from atropine are not uncommon, especially in children. Symptoms The principle manifestations of poisoning with atropine are delirium, tachycardia and fever. Treatment In the treatment of atropine poisoning, respiratory assistance and symptomatic support are indicated.

Physostigmine salicylate, 1 to 5 mL of a dilution containing 1 mg per 5 mL of saline, should be administered intravenously. Administer the smaller dose in children and administer in not less than 2 minutes. Monitor with ECG.

Medication can be repeated every 5 minutes for a total dose of 2 mg in children and every 30 minutes for a total dose of 6 mg in adults. The fatal dose of atropine in children may be as low as 10 mg. In an adult, recovery after 1,000 mg of atropine sulfate has been reported.

Death is usually due to paralysis of the medullary centers. The fatality rate is less than 1%. If the patient survives 24 hours, they will probably recover.

🧬 Clinical Pharmacology 160 words

CLINICAL PHARMACOLOGY The most important therapeutic action of atropine is the inhibition of smooth muscle and glands innervated by postganglionic cholinergic nerves. It also has central nervous system activity, which may be stimulating or depressing depending upon the dose. Following the administration of usual clinical doses, atropine produces stimulation of the medulla and higher cerebral centers.

This effect is manifested by mild central vagal excitation and moderate respiratory stimulation. Atropine sulfate also acts peripherally as a competitive antagonist of the muscarinic actions of acetylcholine. It does not prevent the release of acetylcholine but antagonizes the effect of acetylcholine on the effector cells.

These actions include vasodilation, drying of the mouth, an increase in the pulse rate, inhibition of contractions of the gastrointestinal tract, ureter, and bladder, and reduction of salivary, bronchial, gastric and sweat gland secretions. Following clinical and larger doses, atropine sulfate causes dilation of the pupils and paralysis of accommodation and, in narrow-angle glaucoma, can increase intraocular pressure.
