- 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.
Risk Summary
This formulation of Vancomycin Injection is not recommended for use during 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 is needed during pregnancy, use other available formulations of vancomycin.
There are no available data on vancomycin use in pregnant women to inform a drug-associated risk of major birth defects or miscarriage. Available published data on vancomycin 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, including vancomycin with the excipients PEG 400 and NADA, 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.
Reproduction studies in rabbits with intravenous doses of PEG 400 at approximately 5 times the maximum daily human dose based on body surface area comparisons administered during organogenesis resulted in fetal spinal malformations. Reproduction studies in rabbits and rats using intravenous doses of NADA at approximately 6 and 7 times the maximum daily human dose, respectively, based on body surface area comparisons resulted in maternal toxicity and fetal spinal and cardiovascular malformations in rabbits, and maternal toxicity with no significant 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
There are no available data on first trimester use of vancomycin, including vancomycin with the excipients PEG 400 and NADA, in pregnant women to assess a risk of major birth defects or miscarriage.
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 5 times the maximum daily human dose, based on body surface comparisons) 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 to19) and pregnant rats (gestation days 6 to 17) administered intravenous NADA at 1680 and 3780 mg/kg, respectively (approximately 6 and 7 times the maximum daily human dose, respectively, based on body surface comparisons) resulted in fetal scoliosis and a spectrum of rare 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 fetal skeletal abnormalities were observed in rats at 3780 mg/kg which was also associated with maternal toxicity including increased incidence of litter loss.
No animal studies have been conducted to evaluate the potential reproductive and embryo-fetal effects of Vancomycin Injection.
Risk Summary
There are insufficient data to inform the levels of vancomycin in human milk. 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 and any potential adverse effects on the breastfed infant from vancomycin or from the underlying maternal condition.
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)].
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.
About 60% of an intraperitoneal dose of vancomycin administered during peritoneal dialysis is absorbed systemically in 6 hours. Serum concentrations of about 10 mcg/mL are achieved by intraperitoneal injection of 30 mg/kg of vancomycin. However, the safety and efficacy of the intraperitoneal use of vancomycin has not been established in adequate and well-controlled trials [see Warnings and Precautions (5.7)].
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.
Enterococcus 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

Risk of Embryo-Fetal Toxicity
Advise patients to notify their healthcare provider if they are pregnant prior to treatment with this formulation of vancomycin.
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.
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.
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.
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.
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.
