Why two NDCs? The FDA registers this code as 0409-4883-10 — a 4-4-2 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 labeler segment → 00409-4883-10. Same drug, same package — only the format differs.

5 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.

💲 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 Linezolid — 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 Linezolid. 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.

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 0409-4883-10, 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: 00409-4883-10, written without dashes as 00409488310. 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 00409-4883-10, the first segment (00409) is the labeler code FDA assigned to Hospira, Inc.; the middle segment (4883) identifies this specific product — its ingredient, strength, and dosage form; and the last segment (10) 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 Hospira, Inc.. 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 10 pouches (00409-4883-01). 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?
Hospira, Inc. 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 J2021 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.

🎯 Indications and Usage ~2 min read ▾

1 INDICATIONS AND USAGE Linezolid injection is an oxazolidinone-class antibacterial indicated in adults and children for the treatment of the following infections caused by susceptible Gram-positive bacteria: Nosocomial pneumonia ( 1.1 ); Community-acquired pneumonia ( 1.2 ); Complicated skin and skin structure infections, including diabetic foot infections, without concomitant osteomyelitis ( 1.3 ); Vancomycin-resistant Enterococcus faecium infections. ( 1.4 ) Limitations of Use: ( 1.5 ) • Linezolid injection is not indicated for the treatment of Gram-negative infections. • The safety and efficacy of Linezolid formulations given for longer than 28 days have not been evaluated in controlled clinical trials.

To reduce the development of drug-resistant bacteria and maintain the effectiveness of Linezolid injection formulations and other antibacterial drugs, Linezolid injection should be used only to treat or prevent infections that are proven or strongly suspected to be caused by bacteria. ( 1.6 )

1.1Nosocomial Pneumonia Linezolid injection is indicated for the treatment of nosocomial pneumonia caused by Staphylococcus aureus (methicillin-susceptible and -resistant isolates) or Streptococcus pneumoniae [ see Clinical Studies (14) ].

1.2Community-acquired Pneumonia Linezolid injection is indicated for the treatment of community-acquired pneumonia caused by Streptococcus pneumoniae , including cases with concurrent bacteremia, or Staphylococcus aureus (methicillin-susceptible isolates only) [ see Clinical Studies (14) ].

1.3Complicated Skin and Skin Structure Infections Linezolid injection is indicated for the treatment of complicated skin and skin structure infections, including diabetic foot infections, without concomitant osteomyelitis, caused by Staphylococcus aureus (methicillin-susceptible and -resistant isolates), Streptococcus pyogenes , or Streptococcus agalactiae . Linezolid injection has not been studied in the treatment of decubitus ulcers [ see Clinical Studies (14) ].

1.4Vancomycin-resistant Enterococcus faecium Infections Linezolid injection is indicated for the treatment of vancomycin-resistant Enterococcus faecium infections, including cases with concurrent bacteremia [ see Clinical Studies (14) ].

1.5Limitations of Use • Linezolid injection is not indicated for the treatment of Gram-negative infections. It is critical that specific Gram-negative therapy be initiated immediately if a concomitant Gram-negative pathogen is documented or suspected [ see Warnings and Precautions (5.4) ]. • The safety and efficacy of Linezolid formulations given for longer than 28 days have not been evaluated in controlled clinical trials [ see Clinical Studies (14) ].

1.6Usage To reduce the development of drug-resistant bacteria and maintain the effectiveness of Linezolid injection and other antibacterial drugs, Linezolid injection should be used only to treat or prevent infections that are proven or strongly suspected to be caused by susceptible bacteria. When culture and susceptibility information are available, they should be considered in selecting or modifying antibacterial therapy. In the absence of such data, local epidemiology and susceptibility patterns may contribute to the empiric selection of therapy.

2 DOSAGE AND ADMINISTRATION Dosage, Route, and Frequency of Administration Infection Pediatric Patients (Birth through 11 Years of Age) Adults and Adolescents (12 Years and Older) Duration (days) Nosocomial pneumonia ( 1.1 ) 10 mg/kg intravenously every 8 hours 600 mg intravenously every 12 hours 10 to 14 Community-acquired pneumonia, including concurrent bacteremia ( 1.2 ) Complicated skin and skin structure infections ( 1.3 ) Vancomycin-resistant Enterococcus faecium infections, including concurrent bacteremia ( 1.4 ) 10 mg/kg intravenously every 8 hours 600 mg intravenously every 12 hours 14 to 28 • Pediatric Patients-The recommended dose is 10 mg per kg intravenously every 8 hours.

Linezolid injection in a single-dose container should be used only in pediatric patients who require the entire 600 mg dose and not any fraction thereof. ( 2.1 )

2.1General Dosage and Administration The recommended dosage for Linezolid injection for the treatment of infections is described in Table 1. No dose adjustment is necessary when switching from intravenous to oral administration. Table 1.

Dosage Guidelines for Linezolid Injection Dosage, Route, and Frequency of Administration Recommended Duration of Treatment (consecutive days) Infection Due to the designated pathogens [ see Indications and Usage (1) ] Pediatric Patients Neonates less than 7 days : Most pre-term neonates less than 7 days of age (gestational age less than 34 weeks) have lower systemic linezolid clearance values and larger AUC values than many full-term neonates and older infants. These neonates should be initiated with a dosing regimen of 10 mg/kg every 12 hours.

Consideration may be given to the use of 10 mg/kg every 8 hours regimen in neonates with a sub-optimal clinical response. All neonatal patients should receive 10 mg/kg every 8 hours by 7 days of life [ see Use in Specific Populations (8.4) and Clinical Pharmacology (12.3) ] . (Birth through 11 Years of Age) Adults and Adolescents (12 Years and Older) Nosocomial pneumonia 10 mg/kg intravenously every 8 hours 600 mg intravenously every 12 hours 10 to 14 Community-acquired pneumonia, including concurrent bacteremia Complicated skin and skin structure infections Vancomycin-resistant Enterococcus faecium infections , including concurrent bacteremia 10 mg/kg intravenously every 8 hours 600 mg intravenously every 12 hours 14 to 28 The maximum dose for pediatric patients should not exceed the recommended adult dose.

The recommended dose is 10 mg per kg intravenously every 8 hours. Linezolid injection in a single-dose container should be used only in pediatric patients who require the entire 600 mg dose and not any fraction thereof.

2.2Intravenous Administration Linezolid injection is supplied in single-dose, ready-to-use container [ see How Supplied/Storage and Handling (16) ]. Parenteral drug products should be inspected visually for particulate matter prior to administration. Check for minute leaks by firmly squeezing the bag.

If leaks are detected, discard the solution, as sterility may be impaired . Keep the containers in the overwrap until ready to use. Store at room temperature.

Protect from freezing. Linezolid injection may exhibit a yellow color that can intensify over time without adversely affecting potency. Linezolid injection should be administered by intravenous infusion over a period of 30 to 120 minutes.

Do not use this intravenous container in series connections . Additives should not be introduced into this solution. If Linezolid injection is to be given concomitantly with another drug, each drug should be given separately in accordance with the recommended dosage and route of administration for each product.

Discard unused portion. If the same intravenous line is used for sequential infusion of several drugs, the line should be flushed before and after infusion of Linezolid injection with an infusion solution compatible with Linezolid injection and with any other drug(s) administered via this common l…

⚠️ Warnings and Cautions ~3 min read ▾

5 WARNINGS AND PRECAUTIONS • Myelosuppression: Monitor complete blood counts weekly. Thrombocytopenia has been reported more often in patients with severe renal and in patients with moderate to severe hepatic impairment. Consider discontinuation in patients who develop or have worsening myelosuppression.

( 5.1 ) • Peripheral and Optic Neuropathy: Reported primarily in patients treated for longer than 28 days. If patients experience symptoms of visual impairment, prompt ophthalmic evaluation is recommended. ( 5.2 ) • Serotonin Syndrome: Monitor patients taking Linezolid injection concomitantly with serotonergic agents for signs of serotonin syndrome.

If signs or symptoms of serotonin syndrome occur, consider discontinuing Linezolid injection and/or concomitant serotonergic agents. ( 5.3 ) • A mortality imbalance was seen in an investigational study in linezolid-treated patients with catheter-related bloodstream infections. ( 5.4 ) • Clostridioides difficile- Associated Diarrhea: Evaluate if diarrhea occurs.

( 5.5 ) • Potential interactions producing elevation of blood pressure: monitor blood pressure. ( 5.6 ) • Rhabdomyolysis: If signs or symptoms of rhabdomyolysis are observed, discontinue Linezolid injection and initiate appropriate therapy. ( 5.9 ) • Hypoglycemia: Postmarketing cases of symptomatic hypoglycemia have been reported in patients with diabetes mellitus receiving insulin or oral hypoglycemic agents.

( 5.10 ) • Hyponatremia and/or Syndrome of Inappropriate Antidiuretic Hormone Secretion (SIADH): Monitor serum sodium levels regularly in patients at risk of hyponatremia and/or SIADH. ( 5.11 )

5.1Myelosuppression Myelosuppression (including anemia, leukopenia, pancytopenia, and thrombocytopenia) has been reported in patients receiving linezolid. In cases where the outcome is known, when linezolid was discontinued, the affected hematologic parameters have risen toward pretreatment levels. Thrombocytopenia has been reported more often in patients with severe renal impairment, whether or not on dialysis, and in patients with moderate to severe hepatic impairment.

Complete blood counts should be monitored weekly in patients who receive linezolid, particularly in those who receive linezolid for longer than two weeks, those with pre-existing myelosuppression, those with severe renal impairment or moderate to severe hepatic impairment, those receiving concomitant drugs that produce bone marrow suppression, or those with a chronic infection who have received previous or concomitant antibacterial drug therapy. Discontinuation of therapy with linezolid should be considered in patients who develop or have worsening myelosuppression [ see Adverse Reactions (6.2) ].

5.2Peripheral and Optic Neuropathy Peripheral and optic neuropathies have been reported in patients treated with linezolid, primarily in those patients treated for longer than the maximum recommended duration of 28 days. In cases of optic neuropathy that progressed to loss of vision, patients were treated for extended periods beyond the maximum recommended duration. Visual blurring has been reported in some patients treated with linezolid for less than 28 days.

Peripheral and optic neuropathy has also been reported in children. If patients experience symptoms of visual impairment, such as changes in visual acuity, changes in color vision, blurred vision, or visual field defect, prompt ophthalmic evaluation is recommended. Visual function should be monitored in all patients taking Linezolid injection for extended periods (≥3 months) and in all patients reporting new visual symptoms regardless of length of therapy with Linezolid injection.

If peripheral or optic neuropathy occurs, the continued use of Linezolid injection in these patients should be weighed against the potential risks.

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. Adults The safety of linezolid formulations was evaluated in 2,046 adult patients enrolled in seven Phase 3 comparator-controlled clinical trials, who were treated for up to 28 days. For all indications, 20.4% of linezolid-treated and 14.3% of comparator-treated patients experienced at least one drug-related adverse event.

Table 2 shows the incidence of all-causality, treatment-emergent adverse reactions reported in at least 1% of adult patients in these trials by dose of linezolid. Table 2. Incidence (%) Treatment-Emergent Adverse Reactions Occurring in greater than 1% of Adult Patients Treated with Linezolid in Comparator-Controlled Clinical Trials ADVERSE REACTIONS Linezolid 600 mg every 12 hours (n = 1498) All Other Comparators Comparators included cefpodoxime proxetil 200 mg by mouth every 12 hours; ceftriaxone 1 g intravenously every 12 hours; dicloxacillin 500 mg by mouth every 6 hours; oxacillin 2 g intravenously every 6 hours; vancomycin 1 g intravenously every 12 hours.

1.0Discontinuations due to drug-related adverse events occurred in 2.1% of linezolid-treated and 1.7% of comparator-treated patients. The most common reported drug-related adverse events leading to discontinuation of treatment were nausea, headache, diarrhea, and vomiting. Pediatric Patients The safety of linezolid formulations was evaluated in 215 pediatric patients ranging in age from birth through 11 years, and in 248 pediatric patients aged 5 through 17 years (146 of these 248 were age 5 through 11 and 102 were age 12 to 17).

These patients were enrolled in two Phase 3 comparator-controlled clinical trials and were treated for up to 28 days. In the study of hospitalized pediatric patients (birth through 11 years) with Gram-positive infections, who were randomized 2 to 1 (linezolid: vancomycin), mortality was 6.0% (13/215) in the linezolid arm and 3.0% (3/101) in the vancomycin arm. However, given the severe underlying illness in the patient population, no causality could be established.

For all indications, 18.8% of linezolid-treated and 34.3% of comparator-treated patients experienced at least one drug-related adverse event.

8 USE IN SPECIFIC POPULATIONS

8.1Pregnancy Risk Summary Available data from published and postmarketing case reports with linezolid use in pregnant women have not identified a drug-associated risk of major birth defects, miscarriage, or adverse maternal or fetal outcomes. When administered during organogenesis, linezolid did not cause malformations in mice, rats, or rabbits at maternal exposure levels approximately 6.5 times (mice), equivalent to (rats), or 0.06 times (rabbits) the clinical therapeutic exposure, based on AUCs. However, embryo-fetal lethality was observed in mice at 6.5 times the estimated human exposure.

When female rats were dosed during organogenesis through lactation, postnatal survival of pups was decreased at doses approximately equivalent to the estimated human exposure based on AUCs ( see Data ). The background risk of major birth defects and miscarriage for the indicated populations is unknown. All pregnancies have a background risk of birth defect, loss, or other adverse outcomes.

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 In mice, embryo-fetal toxicities were observed only at doses that caused maternal toxicity (clinical signs and reduced body weight gain). An oral dose of 450 mg/kg/day given from Gestation Day (GD) 6–16 (6.5 times the estimated human exposure based on AUCs) correlated with increased postimplantational embryo death, including total litter loss, decreased fetal body weights, and an increased incidence of costal cartilage fusion.

Neither maternal nor embryo-fetal toxicities were observed at doses up to 150 mg/kg/day. Fetal malformations were not observed. In rats, fetal toxicity was observed at 15 and 50 mg/kg/day administered orally from GD 6–17 (exposures 0.22 times to approximately equivalent to the estimated human exposure, respectively, based on AUCs).

The effects consisted of decreased fetal body weights and reduced ossification of sternebrae, a finding often seen in association with decreased fetal body weights. Fetal malformations were not observed. Maternal toxicity, in the form of reduced body weight gain, was seen at 50 mg/kg/day.

In rabbits, reduced fetal body weight occurred only in the presence of maternal toxicity (clinical signs, reduced body weight gain and food consumption) when administered at an oral dose of 15 mg/kg/day given from GD 6‑20 (0.06 times the estimated human exposure based on AUCs). Fetal malformations were not observed. When female rats were treated with 50 mg/kg/day (approximately equivalent to the estimated human exposure based on AUCs) of linezolid during pregnancy and lactation (GD 6 through Lactation Day 20), survival of pups was decreased on postnatal days 1 to 4.

Male and female pups permitted to mature to reproductive age, when mated, showed an increase in preimplantation loss.

8.2Lactation Risk Summary Linezolid is present in breast milk. Based on data from available published case reports, the daily dose of linezolid that the infant would receive from breastmilk would be approximately 6% to 9% of the recommended therapeutic infant dose (10 mg/kg every 8 hours). There is no information on the effects of linezolid on the breastfed infant; however, diarrhea and vomiting were the most common adverse reactions reported in clinical trials in infants receiving linezolid therapeutically [ see Adverse Reactions (6.1) ] and (see Clinical Considerations ) .

There is no information on the effects of linezolid on milk production. The developmental and health benefits of breastfeeding should be considered along with the mother's clinical need for linezolid and any potential adverse effects on the breastfed child from linezolid or from the underlying maternal condition. Clinical Considerations Advise lactating women to monitor a breastfed infant for diarrhea and vomiting.

🧒 Pediatric Use ~2 min read ▾

8.4Pediatric Use The safety and effectiveness of linezolid for the treatment of pediatric patients with the following infections are supported by evidence from adequate and well-controlled studies in adults, pharmacokinetic data in pediatric patients, and additional data from a comparator-controlled study of Gram-positive infections in pediatric patients ranging in age from birth through 11 years [ see Indications and Usage (1) , Clinical Pharmacology (12.3) and Clinical Studies (14) ]: • nosocomial pneumonia • complicated skin and skin structure infections • community-acquired pneumonia (also supported by evidence from an uncontrolled study in patients ranging in age from 8 months through 12 years) • vancomycin-resistant Enterococcus faecium infections Linezolid injection in a single-dose container should be used only in pediatric patients who require the entire 600 mg dose and not any fraction thereof.

Pharmacokinetic information generated in pediatric patients with ventriculoperitoneal shunts showed variable cerebrospinal fluid (CSF) linezolid concentrations following single and multiple dosing of linezolid; therapeutic concentrations were not consistently achieved or maintained in the CSF. Therefore, the use of linezolid for the empiric treatment of pediatric patients with central nervous system infections is not recommended. The pharmacokinetics of linezolid have been evaluated in pediatric patients from birth to 17 years of age.

In general, weight-based clearance of linezolid gradually decreases with increasing age of pediatric patients. However, in preterm (gestational age <34 weeks) neonates <7 days of age, linezolid clearance is often lower than in full-term neonates <7 days of age. Consequently, preterm neonates <7 days of age may need an alternative linezolid dosing regimen of 10 mg/kg every 12 hours [ see Dosage and Administration (2.1) and Clinical Pharmacology (12.3) ].

In limited clinical experience, 5 out of 6 (83%) pediatric patients with infections due to Gram-positive pathogens with minimum inhibitory concentrations (MICs) of 4 mcg/mL treated with linezolid had clinical cures. However, pediatric patients exhibit wider variability in linezolid clearance and systemic exposure (AUC) compared with adults. In pediatric patients with a sub-optimal clinical response, particularly those with pathogens with MIC of 4 mcg/mL, lower systemic exposure, site and severity of infection, and the underlying medical condition should be considered when assessing clinical response [ see Clinical Pharmacology (12.3) and Dosage and Administration (2) ].

🧓 Geriatric Use 74 words ▾

8.5Geriatric Use Of the 2,046 patients treated with linezolid in Phase 3 comparator-controlled clinical trials, 589 (29%) were 65 years or older and 253 (12%) were 75 years or older. No overall differences in safety or effectiveness were observed between these patients and younger patients, and other reported clinical experience has not identified differences in responses between the elderly and younger patients, but greater sensitivity of some older individuals cannot be ruled out.

🆘 Overdosage 95 words ▾

10 OVERDOSAGE In the event of overdosage, supportive care is advised, with maintenance of glomerular filtration. Hemodialysis may facilitate more rapid elimination of linezolid. In a Phase 1 clinical trial, approximately 30% of a dose of linezolid was removed during a 3-hour hemodialysis session beginning 3 hours after the dose of linezolid was administered.

Data are not available for removal of linezolid with peritoneal dialysis or hemoperfusion. Clinical signs of acute toxicity in animals were decreased activity and ataxia in rats and vomiting and tremors in dogs treated with 3,000 mg/kg/day and 2,000 mg/kg/day, respectively.

12.1Mechanism of Action Linezolid is an antibacterial drug [ see Microbiology (12.4) ].

12.2Pharmacodynamics In a randomized, positive- and placebo-controlled crossover thorough QT study, 40 healthy subjects were administered a single linezolid 600 mg dose via a 1 hour IV infusion, a single linezolid 1,200 mg dose via a 1 hour IV infusion, placebo, and a single oral dose of positive control. At both the 600 mg and 1,200 mg linezolid doses, no significant effect on QTc interval was detected at peak plasma concentration or at any other time.

12.3Pharmacokinetics The mean pharmacokinetic parameters of linezolid in adults after single and multiple oral and intravenous doses are summarized in Table 8. Plasma concentrations of linezolid at steady-state after oral doses of 600 mg given every 12 hours are shown in Figure 1. Table 8.

Plasma Concentrations of Linezolid in Adults at Steady-State Following Oral Dosing Every 12 Hours (Mean ± Standard Deviation, n=16) Absorption Linezolid is extensively absorbed after oral dosing.

Maximum plasma concentrations are reached approximately 1 to 2 hours after dosing, and the absolute bioavailability is approximately 100%. Therefore, linezolid may be given orally or intravenously without dose adjustment. Linezolid may be administered without regard to the timing of meals.

The time to reach the maximum concentration is delayed from 1.5 hours to 2.2 hours and C max is decreased by about 17% when high fat food is given with linezolid. However, the total exposure measured as AUC 0–∞ is similar under both conditions. Distribution Animal and human pharmacokinetic studies have demonstrated that linezolid readily distributes to well-perfused tissues.

The plasma protein binding of linezolid is approximately 31% and is concentration-independent. The volume of distribution of linezolid at steady-state averaged 40 to 50 liters in healthy adult volunteers. Linezolid concentrations have been determined in various fluids from a limited number of subjects in Phase 1 volunteer studies following multiple dosing of linezolid.

The ratio of linezolid in saliva relative to plasma was 1.2 to 1 and the ratio of linezolid in sweat relative to plasma was 0.55 to 1. Metabolism Linezolid is primarily metabolized by oxidation of the morpholine ring, which results in two inactive ring-opened carboxylic acid metabolites: the aminoethoxyacetic acid metabolite (A), and the hydroxyethyl glycine metabolite (B). Formation of metabolite A is presumed to be formed via an enzymatic pathway whereas metabolite B is mediated by a non-enzymatic chemical oxidation mechanism in vitro.

In vitro studies have demonstrated that linezolid is minimally metabolized and may be mediated by human cytochrome P450. However, the metabolic pathway of linezolid is not…

💬 Information for Patients ~3 min read ▾

17 PATIENT COUNSELING INFORMATION Important Administration Instructions Advise patients that Linezolid injection may be taken with or without food. Peripheral and Optic Neuropathy Advise patients to inform their physician if they experience changes in vision while taking Linezolid injection [ see Warnings and Precautions (5.2) ]. Serotonin Syndrome Advise patients to inform their physician if taking serotonergic agents, including serotonin reuptake inhibitors or other antidepressants and opioids.

Advise patients of the increased risk of serotonin syndrome when Linezolid injection is used concomitantly with serotonergic agents [ see Warnings and Precautions (5.3) ]. Potential Interactions Producing Elevation of Blood Pressure • Advise patients to inform their physician if they have a history of hypertension. • Advise patients to avoid large quantities of foods or beverages with high tyramine content while taking Linezolid injection. Foods high in tyramine content include those that may have undergone protein changes by aging, fermentation, pickling, or smoking to improve flavor, such as aged cheeses, fermented or air-dried meats, sauerkraut, soy sauce, tap beers, and red wines.

The tyramine content of any protein-rich food may be increased if stored for long periods or improperly refrigerated. • Advise patients to inform their physician if taking medications containing pseudoephedrine HCl, such as cold remedies and decongestants [ see Warnings and Precautions (5.6) ]. Lactic Acidosis Advise patients to inform their physician if they experience repeated episodes of nausea or vomiting while receiving Linezolid injection [ see Warnings and Precautions (5.7) ]. Convulsions Advise patients to inform their physician if they have a history of seizures or convulsions [ see Warnings and Precautions (5.8) ].

Rhabdomyolysis Advise patients to inform their physician if they experience signs and symptoms of rhabdomyolysis including muscle pain, tenderness or weakness and dark urine [ see Warnings and Precautions (5.9) ]. Hypoglycemia Advise patients to inform their physician if they have diabetes mellitus. Hypoglycemic reactions, such as diaphoresis and tremulousness, along with low blood glucose measurements may occur when treated with linezolid.

If such reactions occur, patients should contact a physician or other health professional for proper treatment [ see Warnings and Precautions (5.10) ]. Hyponatremia and/or SIADH Advise patients at risk for hyponatremia to inform their physician if they experience signs and symptoms of hyponatremia and/or SIADH, including confusion, somnolence, generalized weakness, and respiratory distress [ see Warnings and Precautions (5.11) ]. Antibacterial Resistance Patients should be counseled that antibacterial drugs including Linezolid injection should only be used to treat bacterial infections.

They do not treat viral infections (e.g., the common cold). When linezolid injection is prescribed to treat a bacterial infection, patients should be told that although it is common to feel better early in the course of therapy, the medication should be taken exactly as directed. Skipping doses or not completing the full course of therapy may (1) decrease the effectiveness of the immediate treatment and (2) increase the likelihood that bacteria will develop resistance and will not be treatable by linezolid or other antibacterial drugs in the future.

Diarrhea Diarrhea is a common problem caused by antibacterial drugs, which usually ends when the antibacterial drug is discontinued. Sometimes after starting treatment with antibacterial drugs, patients can develop watery and bloody stools (with or without stomach cramps and fever) even as late as two or more months after having taken the last dose of the antibacterial drug. If this occurs, patients should contact their physician as soon as possible [ see Warnings and Precautions (5.5) ].
