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.

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 51662-1441-1, 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: 51662-1441-01, written without dashes as 51662144101. 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 51662-1441-01, the first segment (51662) is the labeler code FDA assigned to HF Acquisition Co LLC, DBA HealthFirst; the middle segment (1441) identifies this specific product — its ingredient, strength, and dosage form; and the last segment (01) 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.
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.
Does this product have a billing J-code?
Yes — this NDC cross-references HCPCS code J1750 for medical-claim billing (typically used when a product is administered in a clinical setting rather than dispensed at a retail pharmacy). See the Billing section on this page.
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.

🎯 Indications and Usage 27 words

INDICATIONS & USAGE Intravenous or intramuscular injections of INFeD are indicated for treatment of patients with documented iron deficiency in whom oral administration is unsatisfactory or impossible.

⏱️ Dosage and Administration ~3 min read

DOSAGE & ADMINISTRATION Oral iron should be discontinued prior to administration of INFeD. Dosage: I. Iron Deficiency Anemia: Periodic hematologic determination (hemoglobin and hematocrit) is a simple and accurate technique for monitoring hematological response, and should be used as a guide in therapy.

It should be recognized that iron storage may lag behind the appearance of normal blood morphology. Serum iron, total iron binding capacity (TIBC) and percent saturation of transferrin are other important tests for detecting and monitoring the iron deficient state. After administration of iron dextran complex, evidence of a therapeutic response can be seen in a few days as an increase in the reticulocyte count.

Although serum ferritin is usually a good guide to body iron stores, the correlation of body iron stores and serum ferritin may not be valid in patients on chronic renal dialysis who are also receiving iron dextran complex. Although there are significant variations in body build and weight distribution among males and females, the accompanying table and formula represent a convenient means for estimating the total iron required. This total iron requirement reflects the amount of iron needed to restore hemoglobin concentration to normal or near normal levels plus an additional allowance to provide adequate replenishment of iron stores in most individuals with moderately or severely reduced levels of hemoglobin.

It should be remembered that iron deficiency anemia will not appear until essentially all iron stores have been depleted. Therapy, thus, should aim at not only replenishment of hemoglobin iron but iron stores as well. Factors contributing to the formula are shown below. a…Blood volume . . . . . . . . . . . . . . . .65 mL/kg of body weight b.

Normal hemoglobin (males and females) over 15 kg (33 lbs) . . . . . . . . . . .14.8 g/dL 15 kg (33 lbs) or less . . . . . . . . .12.0 g/dL c. Iron content of hemoglobin . . . . . 0.34% d.

Hemoglobin deficit e. Weight Based on the above factors, individuals with normal hemoglobin levels will have approximately 33 mg of blood iron per kilogram of body weight (15 mg/lb). Note: The table and accompanying formula are applicable for dosage determinations only in patients with iron deficiency anemia; they are not to be used for dosage determinations in patients requiring iron replacement for blood loss.

TOTAL INFeD REQUIREMENT FOR HEMOGLOBIN RESTORATION AND IRON STORES REPLACEMENT* *Table values were calculated based on a normal adult hemoglobin of 14.8 g/dL for weights greater than 15 kg (33 lbs) and a hemoglobin of 12.0 g/dL for weights less than or equal to 15 kg (33 lbs). The total amount of INFeD in mL required to treat the anemia and replenish iron stores may be approximated as follows: Adults and Children over 15 kg (33 lbs): See Dosage Table. Alternatively, the total dose may be calculated: Dose (mL) = 0.0442 (Desired Hb - Observed Hb) x LBW + (0.26 x LBW) Based on: Desired Hb = the target Hb in g/dL.

Observed Hb = the patient’s current hemoglobin in g/dL. LBW = Lean body weight in kg. A patient’s lean body weight (or actual body weight if less than lean body weight) should be utilized when determining dosage.

For males: LBW = 50 kg + 2.3 kg for each inch of patient’s height over 5 feet For females: LBW = 45.5 kg + 2.3 kg for each inch of patient’s height over 5 feet To calculate a patient's weight in kg when lbs are known: INFeD should not normally be given in the first four months of life. (See PRECAUTIONS : Pediatric Use). Alternatively, the total dose may be calculated: Dose (mL) = 0.0442 (Desired Hb - Observed Hb) x W + (0.26 x W) Based on: Desired Hb = the target Hb in g/dL.

(Normal Hb for Children 15 kg or less is 12 g/dL) W = Weight in kg. To calculate a patient's weight in kg when lbs are known: II. Iron Replacement for Blood Loss: Some individuals sustain blood losses on an intermittent or repetitive basis.

Such blood losses may occur periodically in patients with he…

⚠️ Warnings ~2 min read

WARNINGS Risk for Anaphylactic-type Reactions: Anaphylactic-type reactions, including fatalities have followed the parenteral administration of iron dextran. Always have resuscitation equipment and personnel trained in the detection and treatment of anaphylactic-type reactions readily available during INFeD administration. Prior to the first therapeutic dose, administer a test INFeD dose of 0.5 mL.

(See DOSAGE AND ADMINISTRATION. ) Although reactions are usually evident within a few minutes, observe patients for at least one hour before administering the therapeutic dose. During all INFeD administrations, observe patients for signs or symptoms of anaphylactic-type reactions. Fatal reactions have followed the test dose of iron dextran and have also occurred in situations where the test dose was tolerated.

Use INFeD only in patients in whom clinical and laboratory investigations have established an iron deficient state not amenable to oral iron therapy. The factors that affect the risk for anaphylactic-type reactions to iron dextran products are not fully known but limited clinical data suggest the risk may be increased among patients with a history of drug allergy or multiple drug allergies. Additionally, concomitant use of angiotensin-converting enzyme inhibitor drugs may increase the risk for reactions to an iron dextran product.

The extent of risk for anaphylactic-type reactions following exposure to any specific iron dextran product is unknown and may vary among the products. Iron dextran products differ in chemical characteristics and may differ in clinical effects. Iron dextran products are not clinically interchangeable.

Delayed Reactions: Large intravenous doses, such as used with total dose infusions (TDI), have been associated with an increased incidence of adverse effects. The adverse effects frequently are delayed (1-2 days) reactions typified by one or more of the following symptoms: arthralgia, backache, chills, dizziness, moderate to high fever, headache, malaise, myalgia, nausea, and vomiting. The onset is usually 24-48 hours after administration and symptoms generally subside within 3-4 days.

The etiology of these reactions is not known. The potential for a delayed reaction must be considered when estimating the risk/benefit of treatment. The maximum daily dose should not exceed 2 mL undiluted iron dextran.

Risk in Patients with Underlying Conditions: INFeD should be used with extreme care in patients with serious impairment of liver function. It should not be used during the acute phase of infectious kidney disease. Adverse reactions experienced following administration of INFeD may exacerbate cardiovascular complications in patients with pre-existing cardiovascular disease.

Carcinogenesis: A risk of carcinogenesis may attend the intramuscular injection of iron-carbohydrate complexes. Such complexes have been found under experimental conditions to produce sarcoma when large doses or small doses injected repeatedly at the same site were given to rats, mice, and rabbits, and possibly in hamsters. The long latent period between the injection of a potential carcinogen and the appearance of a tumor makes it impossible to measure accurately the risk in man.

There have, however, been several reports in the literature describing tumors at the injection site in humans who had previously received intramuscular injections of iron-carbohydrate complexes.

🤒 Adverse Reactions ~1 min read

ADVERSE REACTIONS Severe/Fatal: Anaphylactic reactions have been reported with the use of iron dextran injection; on occasions these reactions have been fatal. Such reactions, which occur most often within the first several minutes of administration, have been generally characterized by sudden onset of respiratory difficulty and/or cardiovascular collapse. Because fatal anaphylactic reactions have been reported after administration of iron dextran injection, the drug should be given only when resuscitation techniques and treatment of anaphylactic and anaphylactoid shock are readily available.

(See BOXED WARNING and PRECAUTIONS : General, pertaining to immediate availability of epinephrine.) Cardiovascular: Chest pain, chest tightness, shock, cardiac arrest, hypotension, hypertension, tachycardia, bradycardia, flushing, arrhythmias. (Flushing and hypotension may occur from too rapid injections by the intravenous route.) Dermatologic: Urticaria, pruritus, purpura, rash, cyanosis. Gastrointestinal: Abdominal pain, nausea, vomiting, diarrhea.

Hematologic/lymphatic: Leucocytosis, lymphadenopathy. Musculoskeletal/soft tissue: Arthralgia, arthritis (may represent reactivation in patients with quiescent rheumatoid arthritis - See PRECAUTIONS : General), myalgia; backache; sterile abscess, atrophy/fibrosis (intramuscular injection site); brown skin and/or underlying tissue discoloration (staining), soreness or pain at or near intramuscular injection sites; cellulitis; swelling; inflammation; local phlebitis at or near intravenous injection site. Neurologic: Convulsions, seizures, syncope, headache, weakness, unresponsiveness, paresthesia, febrile episodes, chills, dizziness, disorientation, numbness, unconsciousness.

Respiratory: Respiratory arrest, dyspnea, bronchospasm, wheezing. Urologic: Hematuria. Delayed reactions: Arthralgia, backache, chills, dizziness, fever, headache, malaise, myalgia, nausea, vomiting.

(See WARNINGS ). Miscellaneous: Febrile episodes, sweating, shivering, chills, malaise, altered taste.

🆘 Overdosage 91 words

OVERDOSAGE Overdosage with iron dextran is unlikely to be associated with any acute manifestations. Dosages of iron dextran in excess of the requirements for restoration of hemoglobin and replenishment of iron stores may lead to hemosiderosis. Periodic monitoring of serum ferritin levels may be helpful in recognizing a deleterious progressive accumulation of iron resulting from impaired uptake of iron from the reticuloendothelial system in concurrent medical conditions such as chronic renal failure, Hodgkin’s disease, and rheumatoid arthritis.

The LD50 of iron dextran is not less than 500 mg/kg in the mouse.

🧬 Clinical Pharmacology ~1 min read

CLINICAL PHARMACOLOGY General: After intramuscular injection, iron dextran is absorbed from the injection site into the capillaries and the lymphatic system. Circulating iron dextran is removed from the plasma by cells of the reticuloendothelial system, which split the complex into its components of iron and dextran. The iron is immediately bound to the available protein moieties to form hemosiderin or ferritin, the physiological forms of iron, or to a lesser extent to transferrin.

This iron which is subject to physiological control replenishes hemoglobin and depleted iron stores. Dextran, a polyglucose, is either metabolized or excreted. Negligible amounts of iron are lost via the urinary or alimentary pathways after administration of iron dextran.

The major portion of intramuscular injections of iron dextran is absorbed within 72 hours; most of the remaining iron is absorbed over the ensuing 3 to 4 weeks. Various studies involving intravenously administered 59Fe iron dextran to iron deficient subjects, some of whom had coexisting diseases, have yielded half-life values ranging from 5 hours to more than 20 hours. The 5-hour value was determined for 59Fe iron dextran from a study that used laboratory methods to separate the circulating 59Fe iron dextran from the transferrin-bound 59Fe.

The 20-hour value reflects a half-life determined by measuring total 59Fe, both circulating and bound. It should be understood that these half-life values do not represent clearance of iron from the body. Iron is not easily eliminated from the body and accumulation of iron can be toxic.

In vitro studies have shown that removal of iron dextran by dialysis is negligible.1,2 Six different dialyzer membranes were investigated (polysulfone, cuprophane, cellulose acetate, cellulose triacetate, polymethylmethacrylate and polyacrylonitrile), including those considered high efficiency and high flux.
