🩺 Clinical

Label name MOXIFLOXACIN 400 MG/250 ML BAG Ingredient Moxifloxacin/Sod.ace,Sul/Water
📖 What it is MedlinePlus · NLM

Moxifloxacin injection is used to treat certain infections caused by bacteria. Moxifloxacin injection is also used to prevent and treat plague (a serious infection that may be spread on purpose as part of a bioterror attack.) Moxifloxacin injection is in a class of antibiotics called fluoroquinolones. It works by killing the bacteria that cause infections. Antibiotics such as moxifloxacin injection will not work for colds, flu, or other viral infections. Using antibiotics when they are not needed increases your risk of getting an infection later that resists antibiotic treatment.

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.

Price systemPer mLPer 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.
Medicare Part B allowsASP · J2281 $6.641 / J2281 unit
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 Moxifloxacin — the program that covers self-administered drugs. 10 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 Moxifloxacin. 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 63323-850-74, 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: 63323-0850-74, written without dashes as 63323085074. 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 63323-0850-74, the first segment (63323) is the labeler code FDA assigned to Fresenius Kabi USA, LLC; the middle segment (0850) identifies this specific product — its ingredient, strength, and dosage form; and the last segment (74) 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 Fresenius Kabi USA, LLC. 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 250 ml (63323-0850-04). 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?
Fresenius Kabi USA, LLC 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 J2281 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.
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.

2.2Administration Instructions Moxifloxacin Injection Solution for Infusion Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration, whenever solution and container permit. Moxifloxacin Injection should be administered by intravenous infusion only. It is not intended for intra-arterial, intramuscular, intrathecal, intraperitoneal, or subcutaneous administration.

Moxifloxacin Injection should be administered by intravenous infusion over a period of 60 minutes by direct infusion or through a Y-type intravenous infusion set which may already be in place.

5.1Disabling and Potentially Irreversible Serious Adverse Reactions Including Tendinitis and Tendon Rupture, Peripheral Neuropathy, and Central Nervous System Effects Fluoroquinolones, including Moxifloxacin Injection, have been associated with disabling and potentially irreversible serious adverse reactions from different body systems that can occur together in the same patient. Commonly seen adverse reactions include tendinitis, tendon rupture, arthralgia, myalgia, peripheral neuropathy, and central nervous system effects (hallucinations, anxiety, depression, insomnia, severe headaches, and confusion).

These reactions can occur within hours to weeks after starting moxifloxacin. Patients of any age or without pre-existing risk factors have experienced these adverse reactions [see Warnings and Precautions ( 5.2 , 5.3 , 5.4 )] . Discontinue Moxifloxacin Injection immediately at the first signs or symptoms of any serious adverse reaction.

In addition, avoid the use of fluoroquinolones, including moxifloxacin, in patients who have experienced any of these serious adverse reactions associated with fluoroquinolones.

5.2Tendinitis and Tendon Rupture Fluoroquinolones, including moxifloxacin, have been associated with an increased risk of tendinitis and tendon rupture in all ages [see Warnings and Precautions ( 5.1 ) and Adverse Reactions ( 6.1 )] . This adverse reaction most frequently involves the Achilles tendon, and has also been reported with the rotator cuff (the shoulder), the hand, the biceps, the thumb, and other tendons. Tendinitis or tendon rupture can occur within hours or days of starting moxifloxacin or as long as several months after completion of therapy.

Tendinitis and tendon rupture can occur bilaterally. The risk of developing fluoroquinolone-associated tendinitis and tendon rupture is increased in patients over 60 years of age, in patients taking corticosteroid drugs, and in patients with kidney, heart or lung transplants. Other factors that may independently increase the risk of tendon rupture include strenuous physical activity, renal failure, and previous tendon disorders such as rheumatoid arthritis.

Tendinitis and tendon rupture have also occurred in patients taking fluoroquinolones who do not have the above risk factors. Discontinue moxifloxacin if the patient experiences pain, swelling, inflammation or rupture of a tendon. Patients should be advised to rest at the first sign of tendinitis or tendon rupture, and to contact their healthcare provider regarding changing to a non- quinolone antimicrobial drug [see Adverse Reactions ( 6.2 ) and Patient Counseling Information ( 17 )].

Avoid fluoroquinolones, including moxifloxacin, in patients who have a history of tendon disorders or have experienced tendinitis or tendon rupture [see Adverse Reactions ( 6.1 )] .

5.3Peripheral Neuropathy Fluoroquinolones, including moxifloxacin, have been associated with an increased risk of peripheral neuropathy. Cases of sensory or sensorimotor axonal polyneuropathy affecting small and/or large axons resulting in paresthesias, hypoesthesias, dysesthesias and weakness have been reported in patients re…

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 to rates in the clinical trials of another drug and may not reflect the rates observed in practice. The data described below reflect exposure to moxifloxacin in 14,981 patients in 71 active controlled Phase II - IV clinical trials in different indications [see Indications and Usage ( 1 )] . The population studied had a mean age of 50 years (approximately 73% of the population was < 65 years of age), 50% were male, 63% were Caucasian, 12% were Asian and 9% were Black.

Patients received moxifloxacin 400 mg once daily PO, IV, or sequentially (IV followed by PO). Treatment duration was usually 6 to 10 days, and the mean number of days on therapy was 9 days. Discontinuation of moxifloxacin due to adverse events occurred in 5% of patients overall, 4.1% of patients treated with 400 mg PO, 3.9% with 400 mg IV and 8.2% with sequential therapy 400 mg PO/IV.

The most common adverse events leading to discontinuation with the 400 mg PO doses were nausea (0.8%), diarrhea (0.5%), dizziness (0.5%), and vomiting (0.4%). The most common adverse event leading to discontinuation with the 400 mg IV dose was rash (0.5%). The most common adverse events leading to discontinuation with the 400 mg IV/PO sequential dose were diarrhea (0.5%) and pyrexia (0.4%).

Adverse reactions occurring in ≥ 1% of moxifloxacin-treated patients and less common adverse reactions, occurring in 0.1 to < 1% of moxifloxacin-treated patients, are shown in Table 2 and Table 3 , respectively. The most common adverse drug reactions (≥ 3%) are nausea, diarrhea, headache, and dizziness.

7 DRUG INTERACTIONS Interacting Drug Interaction Warfarin Anticoagulant effect of warfarin may be enhanced. Monitor prothrombin time/INR, watch for bleeding. ( 6.2 , 7.1 , 12.3 ) Class IA and Class III antiarrhythmics: Proarrhythmic effect may be enhanced. Avoid concomitant use. ( 5.6 , 7.4 ) Antidiabetic agents Carefully monitor blood glucose. ( 5.13 , 7.2 )

7.1Warfarin Quinolones, including moxifloxacin, have been reported to enhance the anticoagulant effects of warfarin or its derivatives in the patient population. In addition, infectious disease and its accompanying inflammatory process, age, and general status of the patient are risk factors for increased anticoagulant activity. Therefore, the prothrombin time, International Normalized Ratio (INR), or other suitable anticoagulation tests should be closely monitored if a quinolone is administered concomitantly with warfarin or its derivatives [see Adverse Reactions ( 6 , 6.1 ,), Clinical Pharmacology ( 12.3 ), and Patient Counseling Information ( 17 )].

7.2Antidiabetic Agents Disturbances of blood glucose, including hyperglycemia and hypoglycemia, have been reported in patients treated concomitantly with fluoroquinolones and an antidiabetic agent. Therefore, careful monitoring of blood glucose is recommended when these agents are co-administered. If a hypoglycemic reaction occurs, moxifloxacin should be discontinued and appropriate therapy should be initiated immediately [see Warnings and Precautions ( 5.13 ), Adverse Reactions ( 6.1 ), and Patient Counseling Information ( 17 )] .

7.3Nonsteroidal Anti-Inflammatory Drugs (NSAIDs) Although not observed with moxifloxacin in preclinical and clinical trials, the concomitant administration of a nonsteroidal anti-inflammatory drug with a quinolone may increase the risks of CNS stimulation and convulsions [see Warnings and Precautions ( 5.4 ), and Patient Counseling Information ( 17 )].

7.4Drugs that Prolong QT There is limited information available on the potential for a pharmacodynamic interaction in humans between moxifloxacin and other drugs that prolong the QTc interval of the electrocardiogram. Sotalol, a Class III antiarrhythmic, has been shown to further increase the QTc interval when combined with high doses of intravenous (IV) moxifloxacin in dogs. Therefore, moxifloxacin should be avoided with Class IA and Class III antiarrhythmics [see Warnings and Precautions ( 5.6 ), Nonclinical Toxicology ( 13.2 ), and Patient Counseling Information ( 17 )].

👥 Use in Specific Populations ~3 min read

8 USE IN SPECIFIC POPULATIONS Pregnancy: Based on animal data may cause fetal harm. ( 8.1 ) Geriatrics: Increased risk for severe tendon disorders further increased by concomitant corticosteroid therapy and increased risk of prolongation of the QT interval. ( 5.2 , 5.6 , 8.5 )

8.1Pregnancy Risk Summary There are no available human data establishing a drug associated risk with the use of moxifloxacin. Based on animal studies, Moxifloxacin Injection may cause fetal harm. Moxifloxacin did not cause fetal malformations when administered to pregnant rats (IV and oral), rabbits (IV) and monkeys (oral) at exposures that were 0.24-2.5 times of those at the human clinical dose (400mg/day moxifloxacin).

However, when moxifloxacin was administered to rats and rabbits during pregnancy and throughout lactation (rats only) at doses associated with maternal toxicity, decreased neonatal body weights, increased incidence of skeletal variations (rib and vertebra combined), and increased fetal loss were observed (see Data ). Advise pregnant women of the potential risk to the fetus. The estimated background risk of major birth defects and miscarriage for the indicated population is unknown.

All pregnancies have a background risk of birth defect. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2 to 4% and 15 to 20%, respectively. Data Animal Data Animal reproductive and development studies were done in rats, rabbits and cynomolgus macaques.

Moxifloxacin did not cause fetal malformations when administered to pregnant rats during organogenesis (gestation days 6 to 17) at oral doses as high as 500 mg/kg/day or 0.24 times the maximum recommended human dose based on systemic exposure (AUC), but decreased fetal body weights and slightly delayed fetal skeletal development were observed. Intravenous administration of 80 mg/kg/day (approximately 2 times the maximum recommended human dose based on body surface area) to pregnant rats resulted in maternal toxicity and a marginal effect on fetal and placental weights and the appearance of the placenta (Gestation days 6 to 17).

Fetal malformations were not observed at intravenous doses as high as 80 mg/kg/day (approximately 2 times the maximum recommended human dose based on body surface area) in litters of pregnant rats that received moxifloxacin during organogenesis (Gestation days 6 to 17). Intravenous administration of 20 mg/kg/day (approximately equal to the maximum recommended human oral dose based upon systemic exposure) to pregnant rabbits during organogenesis (gestation days 6 to 20) resulted in decreased fetal body weights and delayed fetal skeletal ossification.

When rib and vertebral malformations were combined, there was an increased fetal and litter incidence of these effects in rabbits. Signs of maternal toxicity in rabbits at this dose included mortality, abortions, marked reduction of food consumption, decreased water intake, body weight loss and hypoactivity. Fetal malformations were not observed when pregnant cynomolgus macaques were given oral doses as high as 100 mg/kg/day (2.5 times the maximum recommended human dose based upon systemic exposure) during organogenesis (gestation days 20 to 50).

An increased incidence of smaller fetuses was observed at 100 mg/kg/day in macaques. In a pre- and postnatal development study conducted in rats given oral doses from Gestation day 6, throughout gestation and rearing to Postpartum day 21, effects observed at 500 mg/kg/day (0.24 times the maximum recommended human dose based on systemic exposure (AUC)) included slight increases in duration of pregnancy and prenatal loss, reduced pup birth weight and decreased neonatal survival. Treatment-related maternal mortality occurred during gestation at 500 mg/kg/day in this study.

🧒 Pediatric Use ~3 min read

8.4Pediatric Use Effectiveness in pediatric patients and adolescents less than 18 years of age has not been established. Moxifloxacin causes arthropathy in juvenile animals. Limited information on the safety of Moxifloxacin in 301 pediatric patients is available from the cIAI trial [see Boxed Warning , Warnings and Precautions ( 5.9 ) and Nonclinical Toxicology ( 13.2 )].

Active Controlled Trial in Complicated Intra-Abdominal Infection (cIAI) The safety and efficacy of Moxifloxacin Injection in pediatric patients for the treatment of cIAI has not been demonstrated. Pediatric patients 3 months to <18 years of age (mean age of 12 ± 4 years) were enrolled in a single randomized, double-blind, active controlled trial in cIAI including appendicitis with perforation, abscesses and peritonitis. Pediatric patients were randomized (2:1) to receive either Moxifloxacin or comparator.

This study enrolled 451 patients who received study medication, 301 treated with moxifloxacin, and 150 with comparator. Of the 301 pediatric patients treated with Moxifloxacin, 15 were below the age of 6 years and 286 were between the ages of 6–18 years. Patients received sequential intravenous/oral Moxifloxacin or comparator (intravenous ertapenem followed by oral amoxicillin/clavulanate) for 5 to 14 days (mean duration was 9 days with a range of 1 to 24 days).

The overall adverse reaction profile in pediatric patients was comparable to that of adult patients. The most frequently occurring adverse reactions in pediatric patients treated with Moxifloxacin were QT prolongation 9.3% (28/301), vomiting, 6.6% (20/301) diarrhea 3.7% (11/301), arthralgia 3.0% (9/301), and phlebitis 2.7% (8/301) (see Table 5 ). Discontinuation of study drug due to an adverse reaction was reported in 5.3% (16/301) of Moxifloxacin-treated patients versus 1.3% (2/150) of comparator-treated patients.

The adverse reaction profile of Moxifloxacin or comparator was similar across all age groups studied. Musculoskeletal adverse reactions were monitored and followed up to 5 years after the end of study treatment. The rates of musculoskeletal adverse reactions were 4.3% (13/301) in the Moxifloxacin-treated group versus 3.3% (5/150) in the comparator-treated group.

The majority of musculoskeletal adverse reactions were reported between 12 and 53 weeks after start of study treatment with complete resolution at the end of the study [see Warnings and Precautions ( 5.12 ) and Nonclinical Toxicology ( 13.2 )]. Table 5 Incidence (%) of Selected Adverse Reactions in ≥2.0% of Pediatric Patients Treated with Moxifloxacin Injection in cIAI Clinical Trial System Organ Class Adverse Reactions Moxifloxacin Injection N = 301 (%) Comparator N = 150 (%) Gastrointestinal disorders Abdominal pain 8 (2.7) 3 (2.0) Diarrhea 11 (3.7) 1 (0.7) Vomiting 20 (6.6) 12 (8.0) General disorders and administration site conditions Pyrexia 6 (2.0) 4 (2.7) Investigations Aspartate aminotransferase increased 2 (0.7) 3 (2.0) Electrocardiogram QT prolonged 28 (9.3) 4 (2.7) Musculoskeletal and connective tissue disorders Arthralgia 9 (3.0) 2 (1.3) Nervous system disorders Headache 6 (2.0) 2 (1.3) Vascular disorders Phlebitis 8 (2.7) 0 (0) Clinical response was assessed at the test-of-cure visit (28 to 42 days after end of treatment).

🧓 Geriatric Use ~2 min read

8.5Geriatric Use Geriatric patients are at increased risk for developing severe tendon disorders including tendon rupture when being treated with a fluoroquinolone such as Moxifloxacin Injection. This risk is further increased in patients receiving concomitant corticosteroid therapy. Tendinitis or tendon rupture can involve the Achilles, hand, shoulder, or other tendon sites and can occur during or after completion of therapy; cases occurring up to several months after fluoroquinolone treatment have been reported.

Caution should be used when prescribing Moxifloxacin Injection to elderly patients especially those on corticosteroids. Patients should be informed of this potential side effect and advised to discontinue Moxifloxacin Injection and contact their healthcare provider if any symptoms of tendinitis or tendon rupture occur [see Boxed Warning , Warnings and Precautions ( 5.1 , 5.2 ), and Adverse Reactions ( 6.2 )]. Epidemiologic studies report an increased rate of aortic aneurysm and dissection within two months following use of fluoroquinolones, particularly in elderly patients [see Warnings and Precautions ( 5.9 )].

Moxifloxacin Injection contains 1,207 mg (52.5 mEq) of sodium per unit dose. The geriatric population may respond with a blunted natriuresis to salt loading. This may be clinically important with regard to such diseases as congestive heart failure [see Warnings and Precautions ( 5.11 )] .

In controlled multiple-dose clinical trials, 23% of patients receiving oral moxifloxacin were greater than or equal to 65 years of age and 9% were greater than or equal to 75 years of age. The clinical trial data demonstrate that there is no difference in the safety and efficacy of oral moxifloxacin in patients aged 65 or older compared to younger adults. In trials of intravenous use, 42% of moxifloxacin patients were greater than or equal to 65 years of age, and 23% were greater than or equal to 75 years of age.

The clinical trial data demonstrate that the safety of intravenous moxifloxacin in patients aged 65 or older was similar to that of comparator-treated patients. In general, elderly patients may be more susceptible to drug-associated effects of the QT interval. Therefore, Moxifloxacin Injection should be avoided in patients taking drugs that can result in prolongation of the QT interval (for example, Class IA or Class III antiarrhythmics) or in patients with risk factors for torsades de pointes (for example, known QT prolongation, uncorrected hypokalemia) [see Warnings and Precautions ( 5.6 ), Drug Interactions ( 7.4 ), and Clinical Pharmacology ( 12.3 )].

🆘 Overdosage 104 words

10 OVERDOSAGE Single oral overdoses up to 2.8 g were not associated with any serious adverse events. In the event of acute overdose, the stomach should be emptied and adequate hydration maintained. ECG monitoring is recommended due to the possibility of QT interval prolongation.

The patient should be carefully observed and given supportive treatment. The administration of activated charcoal as soon as possible after oral overdose may prevent excessive increase of systemic moxifloxacin exposure. About 3% and 9% of the dose of moxifloxacin, as well as about 2% and 4.5% of its glucuronide metabolite are removed by continuous ambulatory peritoneal dialysis and hemodialysis, respectively.

12.1Mechanism of Action Moxifloxacin is a member of the fluoroquinolone class of antibacterial agents [see Microbiology ( 12.4 )].

12.3Pharmacokinetics The mean (± SD) pharmacokinetic parameters of moxifloxacin following single and multiple dose of 400 mg moxifloxacin given by 1 hour intravenous infusion are summarized in Table 7 . The mean (± SD) elimination half-life from plasma is 12 ± 1.3 hours; steady-state is achieved after at least three days with a 400 mg once daily regimen. The absolute bioavailability of moxifloxacin is approximately 90 percent.

When switching from intravenous to oral formulation, no dosage adjustment is necessary [see Dosage and Administration ( 2.1 )].

2.7Distribution Moxifloxacin is approximately 30 to 50% bound to serum proteins, independent of drug concentration. The volume of distribution of moxifloxacin ranges from 1.7 to

2.7L/kg. Moxifloxacin is widely distributed throughout the body, with tissue concentrations often exceeding plasma concentrations. Moxifloxacin has been detected in the saliva, nasal and bronchial secretions, mucosa of the sinuses, skin blister fluid, subcutaneous tissue, skeletal muscle, and abdominal tissues and fluids following oral or intravenous administration of 400 mg.

Moxifloxacin concentrations measured post-dose in various tissues and fluids following a 400 mg oral or intravenous dose are summarized in Table 8 .
