( 2.1 ) For intravenous use only. Do Not administer orally. Administer Vancomycin Injection by intravenous infusion over 60 minutes or greater to reduce the risk of infusion reactions ( 2.1 ) Adult Patients: 2 g divided either as 0.5 grams (g) every 6 hours or 1 g every 12 hours ( 2.2 ) Pediatric Patients (1 Month and Older): 10 mg/kg per dose given every 6 hours ( 2.3 ) Patients with Renal Impairment: See full prescribing information for recommended doses in patients with renal impairment ( 2.4 ) See full prescribing information for further important administration and preparation instructions ( 2.1 , 2.5 ) 2.1 Important Administration Instructions Obtain a pregnancy test in females of reproductive potential prior to initiating treatment with Vancomycin Injection [see Warnings and Precautions (5.1) , and Use in Specific Populations (8.1 , 8.3) ]. Use this formulation of Vancomycin Injection only in patients who require the entire (500 mg, 750 mg, 1 g, 1.25 g, 1.5 g, 1.75 g or 2 g) dose and not any fraction thereof. Vancomycin Injection in transparent single-dose flexible bags are intended for intravenous use only. Do NOT administer orally. To reduce the risk of infusion related adverse reactions, administer Vancomycin Injection by intravenous infusion over 60 minutes or greater [see Warnings and Precautions (5.2) and Adverse Reactions (6.1) ] . An infusion rate of 10 mg/min or less is associated with fewer infusion-related events [see Warnings and Precautions (5.2) ] . Infusion related events may occur, however, at any rate or concentration. Drug additives should not be made to this solution. Vancomycin Injection concentrations of no more than 5 mg/mL are recommended in adults [see Dosage and Administration (2.2) ] . See also age-specific recommendations [see Dosage and Administration (2.3) ] . Administer Vancomycin Injection prior to intravenous anesthetic agents to reduce the risk of infusion related adverse reactions [see Warnings and Precautions (5.2) ] . Administer Vancomycin Injection by a secure intravenous route of administration to avoid local irritation and phlebitis reactions [see Warnings and Precautions (5.9) ] . 2.2 Dosage in Adult Patients with Normal Renal Function The usual daily intravenous dose is 2 g divided either as 500 mg every 6 hours or 1 g every 12 hours. Administer each dose by intravenous infusion over a period of 60 minutes or greater. Other patient factors, such as age or obesity, may call for modification of the usual intravenous daily dose. The initial daily dose should be no less than 15 mg/kg. 2.3 Dosage in Pediatric Patients (1 Month and Older) with Normal Renal Function Use this formulation of Vancomycin Injection only in pediatric patients (1 month and older) who require the entire dose (500 mg, 750 mg, 1 g, 1.25 g, 1.5 g, 1.75 g or 2 g) of this single-dose flexible bag and not any fraction of it [see Dosage Forms and Strengths (3) ]. The usual intravenous dosage of vancomycin is 10 mg/kg per dose given every 6 hours. Each dose should be administered over a period of at least 60 minutes. Close monitoring of serum concentrations of vancomycin may be warranted in these patients. 2.4 Dosage in Patients with Renal Impairment Dosage adjustment must be made in patients with renal impairment. The initial dose should be no less than 15 mg/kg in patients with any degree of renal impairment. In the elderly, greater dosage reductions than expected may be necessary because of decreased renal function. Measure trough vancomycin serum concentrations to guide therapy, especially in seriously ill patients with changing renal function. For functionally anephric patients, an initial dose of 15 mg/kg of body weight should be given to achieve prompt therapeutic serum concentration. A dose of 1.9 mg/kg/24 h should be given after the initial dose of 15 mg/kg. 2.5 Directions for Use of Vancomycin Injection and Storage Instructions Vancomycin Injection in transparent single-dose flexible bag is for intravenous administration only. Vancomycin Injection is room temperature stable, ready-to-use drug product. Preparation for Intravenous Administration: Remove the flexible bag from aluminum overpouch. Check for minute leaks by squeezing the bag firmly. If leaks are detected, discard solution because sterility may be impaired. Leaks may be more readily detected by wrapping the bag with blotting paper or a tissue before squeezing. Do not add supplemental medication. Visually inspect the flexible bag. If the outlet port protector is damaged, detached, or not present, discard the flexible bag as solution path sterility may be impaired. If after visual inspection the solution is cloudy or if an insoluble precipitate is noted or if any seals are not intact, the flexible bag should be discarded. The solution in the flexible bag remains chemically stable for 28 days at room temperature (up to 25°C/77°F) after removal from the aluminum overpouch. Discard unused drug. Suspend the flexible bag from eyelet support. Remove protector from outlet port at bottom of flexible bag. Attach administration set. Refer to complete directions accompanying set. Use sterile equipment. Do NOT use flexible bags in series connections. Such use could result in an embolism due to residual air being drawn from the primary container before administration of the fluid from the secondary container is complete. 2.6 Incompatibilities for Intravenous Use Vancomycin solution has a low pH and may cause chemical or physical instability when it is mixed with other compounds. Mixtures of solutions of vancomycin and beta-lactam antibacterial drugs have been shown to be physically incompatible. The likelihood of precipitation increases with higher concentrations of vancomycin. It is recommended to adequately flush the intravenous lines between the administration of these antibacterial drugs.

In the absence of such data, local epidemiology and susceptibility patterns may contribute to the empiric selection of therapy.
Overdosage
10 OVERDOSAGE Supportive care is advised, with maintenance of glomerular filtration. Vancomycin is poorly removed by dialysis. Hemofiltration and hemoperfusion with polysulfone resin have been reported to result in increased vancomycin clearance. For current information on the management of overdosage, contact the National Poison Control Center at 1-800-222-1222 or www.poison.org.

Clinical Pharmacology
12 CLINICAL PHARMACOLOGY 12.1 Mechanism of Action Vancomycin is an antibacterial drug [see Microbiology (12.4) ] . 12.2 Pharmacodynamics The pharmacodynamics of vancomycin is unknown. 12.3 Pharmacokinetics In subjects with normal kidney function, multiple intravenous dosing of 1 g of vancomycin (15 mg/kg) infused over 60 minutes produces mean plasma concentrations of approximately 63 mcg/mL immediately after the completion of infusion, mean plasma concentrations of approximately 23 mcg/mL 2 hours after infusion, and mean plasma concentrations of approximately 8 mcg/mL 11 hours after the end of the infusion. Multiple dosing of 500 mg infused over 30 minutes produces mean plasma concentrations of about 49 mcg/mL at the completion of infusion, mean plasma concentrations of about 19 mcg/mL 2 hours after infusion, and mean plasma concentrations of about 10 mcg/mL 6 hours after infusion. The plasma concentrations during multiple dosing are like those after a single dose. In healthy subjects administered a single 1g dose of Vancomycin Injection, geometric mean (geometric %CV) AUC 0-inf values for NADA, PEG 400, and vancomycin were 209 (19.6%), 405 (12.5%), and 219 (13.7%) mcg*h/mL, respectively. Based on a population pharmacokinetic analysis, 1g Vancomycin Injection administered over 1.5 hours every 12 hours achieves a geometric mean (95% prediction interval) steady state AUC 0-24 exposure of 384 (277-547) , 734 (550-994), and 384 (261-567) mcg*h/mL for NADA, PEG 400, and vancomycin in healthy subjects, respectively. Distribution The volume of distribution ranges from 0.3 to 0.43 L/kg after intravenous administration. Vancomycin is approximately 55% serum protein bound as measured by ultrafiltration at vancomycin serum concentrations of 10 to 100 mcg/mL. After intravenous administration of vancomycin, inhibitory concentrations are present in pleural, pericardial, ascitic, and synovial fluids; in urine; in peritoneal dialysis fluid; and in atrial appendage tissue. Vancomycin does not readily diffuse across normal meninges into the spinal fluid; but, when the meninges are inflamed, penetration into the spinal fluid occurs. Elimination Mean plasma clearance is about 0.058 L/kg/h, and mean renal clearance is about 0.048 L/kg/h. The mean elimination half-life of vancomycin from plasma is 4 to 6 hours in subjects with normal renal function. In anephric patients, the mean elimination half-life is 7.5 days. Total body and renal clearance of vancomycin may be reduced in the elderly. Metabolism There is no apparent metabolism of the vancomycin. Excretion In the first 24 hours after intravenous administration, about 75% of an administered dose of vancomycin is excreted in urine by glomerular filtration. Renal impairment slows excretion of vancomycin. In the first 48 hours after intravenous administration of a single 1 g dose of Vancomycin Injection, the percent excreted unchanged in urine was approximately 80% and 50% for NADA and PEG 400, respectively. 12.4 Microbiology Mechanism of Action The bactericidal action of vancomycin results primarily from inhibition of cell-wall biosynthesis. In addition, vancomycin alters bacterial-cell-membrane permeability and RNA synthesis. Resistance Vancomycin is not active in vitro against gram-negative bacilli, mycobacteria, or fungi. There is no cross-resistance between vancomycin and other antibacterials. Interaction with Other Antimicrobials The combination of vancomycin and an aminoglycoside acts synergistically in vitro against many isolates of Staphylococcus aureus , Streptococcus gallolyticus (previously known as Streptococcus bovis ), Enterococcus spp, and the viridans group streptococci. Antimicrobial Activity Vancomycin has been shown to be active against most isolates of the following bacteria, both in vitro and in clinical infections [see Indications and Usage (1) ] . Aerobic Gram-Positive Bacteria Corynebacterium spp. Enterococcu s spp. (including Enterococcus faecalis ) Staphylococcus aureus (including methicillin-resistant and methicillin-susceptible isolates) Coagulase negative staphylococci (including S.epidermidis and methicillin-resistant isolates) Streptococcus gallolyticus (previously known as Streptococcus bovis ) Viridans group streptococci The following in vitro data are available, but their clinical significance is unknown. At least 90 percent of the following bacteria exhibit an in vitro minimum inhibitory concentration (MIC) less than or equal to the susceptible breakpoint for vancomycin against isolates of similar genus or organism group. However, the efficacy of vancomycin in treating clinical infections caused by these bacteria has not been established in adequate and well-controlled clinical trials. Aerobic Gram-Positive Bacteria Listeria monocytogenes Streptococcus pyogenes Streptococcus pneumoniae Streptococcus agalactiae Anaerobic Gram-Positive Bacteria Actinomyces species Lactobacillus species Susceptibility Testing For specific information regarding susceptibility test interpretive criteria and associated test methods and quality control standards recognized by FDA for this drug, please see: https://www.fda.gov/STIC.

Information For Patients
17 PATIENT COUNSELING INFORMATION Potential Risk of Exposure to Excipients During the First or Second Trimester of Pregnancy Advise patients to notify their healthcare provider if they are pregnant prior to treatment with this formulation of vancomycin [see Boxed Warning , Warnings and Precautions (5.1) and Use in Specific Populations (8.1) ]. Infusion Reactions During or After Intravenous Use Advise patients that generalized skin redness, skin rash, itching, flushing, muscle pain, chest pain, shortness of breath, wheezing, or dizziness may occur during Vancomycin Injection infusion. These reactions can be lessened or prevented by infusing the drug over at least 60 minutes [see Warnings and Precautions (5.2) ] . Acute Kidney Injury Advise patients that Vancomycin Injection can result in kidney damage and that blood tests are required to monitor vancomycin blood levels and kidney function during therapy [see Warnings and Precautions (5.3) ] . Hearing Loss or Balance Problems Advise patients that Vancomycin Injection may result in decreased hearing and to report hearing loss or balance problems to their health care provider [see Warnings and Precautions (5.4) ] . Severe Dermatologic Reactions Advise patients about the signs and symptoms of serious skin manifestations. Instruct patients to stop Vancomycin Injection immediately and promptly report the first signs or symptoms of skin rash, mucosal lesions or blisters to their healthcare provider [see Warnings and Precautions (5.5) ] . Diarrhea Diarrhea is a common problem caused by antibacterial drugs, including vancomycin, 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 (5.2) ] . Antibacterial Resistance Patients should be counseled that antibacterial drugs including vancomycin, should only be used to treat bacterial infections. They do not treat viral infections (e.g., the common cold). When vancomycin 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 vancomycin or other antibacterial drugs in the future.

Geriatric Use
8.5 Geriatric Use Vancomycin is known to be substantially excreted by the kidney, and the risk of adverse reactions to this drug may be greater in patients with impaired renal function. Because elderly patients are more likely to have decreased renal function, care should be taken in dose selection [see Dosage and Administration (2.2) ] , and it may be useful to monitor renal function [see Warnings and Precautions (5.2) ] .
Pediatric Use
8.4 Pediatric Use Vancomycin Injection is indicated in pediatric patients (1 month and older) [see Indications and Usage (1.1 to 1.5) and Dosage and Administration (2.2) ]. In pediatric patients, monitor vancomycin serum concentration and renal function when administering Vancomycin Injection [see Dosage and Administration (2.2 , 2.3) and Warnings and Precautions (5.2) ] . More severe infusion related reactions related to vancomycin administration may occur in pediatric patients. Concomitant administration of vancomycin and intravenous anesthetic agents has been associated with erythema and histamine-like flushing in all patients including pediatric patients [see Warnings and Precautions (5.2) ] .
Pregnancy
8.1 Pregnancy Risk Summary This formulation of Vancomycin Injection is not recommended for use during the first or second trimester of pregnancy because it contains the excipients, PEG 400 and NADA, which caused fetal malformations in animal reproduction studies (see Data ) . Advise pregnant women of the potential risk to the fetus. If therapy with Vancomycin Injection is needed during the first or second trimester of pregnancy, use other available formulations of vancomycin, free of PEG 400 and NADA. The available data on use of this formulation of Vancomycin Injection (with the excipients PEG 400 and NADA) in pregnant women are insufficient to evaluate for a drug-associated risk of major birth defects, miscarriage, or other adverse maternal or fetal outcomes. Available published data on vancomycin (without the excipients PEG 400 and NADA) use in pregnancy during the second and third trimesters have not shown an association with adverse pregnancy related outcomes (see Data ) . There are no available data on first trimester use of vancomycin in pregnant women to assess the risk of major birth defects or miscarriage. Vancomycin alone did not show adverse developmental effects when administered intravenously to pregnant rats and rabbits during organogenesis at doses less than or equal to the recommended maximum human dose based on body surface area (see Data ) . Reproduction studies in rabbits with intravenous doses of PEG 400 at approximately 8 times the maximum daily human dose based on systemic exposures of PEG 400 during organogenesis resulted in fetal spinal malformations. Reproduction studies in rabbits and rats using intravenous doses of NADA at approximately 32 and 20 times the maximum daily human dose, respectively, based on systemic exposures of NADA resulted in maternal toxicity and fetal spinal and cardiovascular malformations in rabbits, and maternal toxicity with no adverse embryo-fetal effects in rats. Vancomycin alone did not show adverse developmental effects when administered intravenously to pregnant rats and rabbits during organogenesis at doses less than or equal to the recommended maximum human dose based on body surface area (see Data ) . 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 Human Data Available data from postmarketing cases on use of this formulation of vancomycin injection (with the excipients PEG 400 and NADA) in pregnant women are insufficient to evaluate for a drug-associated risk of major birth defects, miscarriage, or other adverse maternal or infant outcomes. There are no available data on first trimester use of vancomycin (without the excipients PEG 400 and NADA); however, available published data on use in pregnancy during the second and third trimesters have not shown an association with adverse pregnancy related outcomes. A published study evaluated hearing loss and nephrotoxicity in infants of 10 pregnant intravenous drug users treated with vancomycin (formulation did not include the excipients PEG 400 and NADA) for suspected or documented methicillin-resistant Staphylococcus aureus in the second or third trimester. The comparison groups were 10 uninfected non-intravenous drug-dependent patients, and 10 uninfected intravenous drug-dependent patients who served as substance abuse controls. No infant in the vancomycin exposed group had abnormal sensorineural hearing at 3 months of age or nephrotoxicity. A published prospective study assessed outcomes in 55 pregnant women with a positive Group B streptococcus (GBS) culture and a high-risk penicillin allergy with resistance to clindamycin or unknown sensitivity who were administered vancomycin (formulation did not include the excipients PEG 400 and NADA) at the time of delivery. Vancomycin dosing ranged from the standard 1 g intravenously every 12 hours to 20 mg/kg intravenous every 8 hours (maximum individual dose 2 g). No major adverse reactions were recorded either in the mothers or their newborns. None of the newborns had sensorineural hearing loss. Neonatal renal function was not examined, but all of the newborns were discharged in good condition. Animal Data Vancomycin did not cause fetal malformations when administered during organogenesis to pregnant rats (gestation days 6 to 15) and rabbits (gestation days 6 to 18) at the equivalent recommended maximum human dose (based on body surface area comparisons) of 200 mg/kg/day IV to rats or 120 mg/kg/day IV to rabbits. No effects on fetal weight or development were seen in rats at the highest dose tested or in rabbits given 80 mg/kg/day (approximately 1 and 0.8 times the recommended maximum human dose based on body surface area, respectively). Maternal toxicity was observed in rats (at doses 120 mg/kg and above) and rabbits (at 80 mg/kg and above). Animal reproduction studies conducted in rabbits administered intravenous PEG 400 at 2000 mg/kg (approximately 8 times the maximum daily human dose, based on AUC levels of PEG 400) during organogenesis (gestation days 6 to 19) resulted in fetal scoliosis (thoracic and lumbar) and increased incidence of delayed or incomplete ossification of the pubes, epiphyses, and talus bones. No maternal toxicity was observed up to the maximum dose tested. Similarly, in animal reproduction studies conducted in pregnant rabbits (gestation days 6 to 19) and pregnant rats (gestation days 6 to 17) administered intravenous NADA at 1680 and 3780 mg/kg, respectively (at 32 times or greater based on AUC levels of NADA) resulted in fetal scoliosis and a spectrum of cardiovascular anomalies in rabbits and no adverse effects on fetuses in rats. Increased incidence of delayed or incomplete ossifications of the metacarpals/metatarsals/phalanges and increased ossification (fused jugal/maxilla bones) were observed in rabbits at 1680 mg/kg. Minor non adverse fetal skeletal abnormalities were observed in rats at 3780 mg/kg which was also associated with maternal toxicity including increased incidence of litter loss [see Clinical Pharmacology (12.3) ] . No animal studies have been conducted to evaluate the potential reproductive and embryo-fetal effects of Vancomycin Injection (with the excipients PEG 400 and NADA).

There are no data on the effects of vancomycin on the breastfed infant or milk production. The developmental and health benefits of breastfeeding should be considered along with the mother's clinical need for Vancomycin Injection and any potential adverse effects on the breastfed infant from Vancomycin Injection or from the underlying maternal condition. 8.3 Females and Males of Reproductive Potential Pregnancy Testing Perform a pregnancy test in females of reproductive potential prior to prescribing this formulation of vancomycin [see Warnings and Precautions (5.1) and Use in Specific Populations (8.1) ] . 8.4 Pediatric Use Vancomycin Injection is indicated in pediatric patients (1 month and older) [see Indications and Usage (1.1 to 1.5) and Dosage and Administration (2.2) ]. In pediatric patients, monitor vancomycin serum concentration and renal function when administering Vancomycin Injection [see Dosage and Administration (2.2 , 2.3) and Warnings and Precautions (5.2) ] . More severe infusion related reactions related to vancomycin administration may occur in pediatric patients. Concomitant administration of vancomycin and intravenous anesthetic agents has been associated with erythema and histamine-like flushing in all patients including pediatric patients [see Warnings and Precautions (5.2) ] . 8.5 Geriatric Use Vancomycin is known to be substantially excreted by the kidney, and the risk of adverse reactions to this drug may be greater in patients with impaired renal function.
