Inhibits bacterial cell wall synthesis and alters cell-membrane permeability and RNA synthesis.
Poorly absorbed (orally). C max is 63 mcg/mL and T max is 1 h (injection).
55% protein bound. Vd is 0.3 to 0.43 L/kg. Distributes in pleural, pericardial, ascitic, and synovial fluids; in urine; in peritoneal dialysis fluid; and in atrial appendage tissue.
No apparent metabolism of the drug.
Mean half-life is 4 to 6 h. About 75% is excreted in the urine by glomerular filtration (in the first 24 h). Mean plasma Cl is 0.058 L/kg/h. Renal Cl is 0.048 L/kg/h.
Special PopulationsRenal Function Impairment
Renal impairment slows excretion of vancomycin; in anephric patients, half-life is 7.5 days. Dosage adjustment is required.Elderly
Total systemic and renal Cl may be reduced.

Add 25 mg/mL to the parenteral nutrition solution and administer as a continuous infusion or as a flush/lock.Hospital-acquired pneumonia Adults
IV 15 mg/kg every 12 h.Preoperative antimicrobial prophylaxis
For cardiac surgery (prosthetic valve or pacemaker), neurosurgery (craniotomy), and orthopedic surgery (internal fixation of fractures or prosthetic joints), the preoperative dose in children is 10 mg/kg IV if the likely pathogens include methicillin-resistant Staphylococcus aureus or methicillin-resistant Staphylococcus epidermidis .
For GU and GI tract (excluding esophageal) procedures, the preoperative dose in adults is 1 g IV given over 1 to 2 h plus gentamicin 1.5 mg/kg (up to 120 mg) IV or IM. In children, the preoperative dose is 20 mg/kg IV given over 1 to 2 h plus gentamicin 1.5 mg/kg IV or IM. Complete the infusion/injection within 30 min of starting the procedure. This regimen is indicated for high-risk patients who are allergic to ampicillin or amoxicillin. For moderate-risk patients who are allergic to ampicillin or amoxicillin, the regimen excludes gentamicin.Rectal administration Adults
Initial doses of 1 to 2 g and maintenance dosing of 100 to 500 mg every 6 h. Administration is recommended as an enema or with a Bardex catheter (as with a barium enema).Ventricular shunt infection Children
IV Systemic vancomycin is generally given at a dosage of 15 mg/kg every 6 h. Also administer 10 mg/day (50 mg/mL diluted with normal saline to a final concentration of 5 mg/mL) directly into the ventricle (if the shunt is not externalized) or into the externalized shunt, which is then clamped for 1 h after administration.Other infections in children Severe infections, including CNS infections (meningitis) Adolescents

IV 1 g every 4 to 7 days.Anephric patients Adults
IV Initial dose of 15 mg/kg followed by 1.9 mg/kg every 24 h or 250 to 1,000 mg every 7 to 10 days.Anuria Adults
IV 1,000 mg every 7 to 10 days.
- Reconstituted powder must be further diluted prior to administration.
- Concentrations of no more than 5 mg/mL and rates of no more than 10 mg/min are recommended in adults.
- Administer over a period of no less than 60 min by intermittent infusion.
- Other patient factors, such as age or obesity, may call for modification of the usual IV daily dose.
- The total daily IV dosage may be lower in neonates. In premature infants, vancomycin Cl decreases as postconceptional age decreases. Therefore, longer dosing intervals may be necessary in premature infants. Close monitoring of serum concentrations of vancomycin may be warranted in these patients.
- Certain parenteral products may be administered orally. Dilute in 1 oz of water. Common flavoring syrups may be added to the solution. The diluted solution may be given via nasogastric tube.
- Thaw frozen Galaxy containers at room temperature or under refrigeration. Do not thaw by water bath immersion or by microwave.
Store vials at 68° to 77°F. After reconstitution, vials may be stored in a refrigerator for 14 days. Solutions diluted with dextrose 5% or sodium chloride 0.9% may be stored in a refrigerator for 14 days; solutions diluted with Ringer's lactate, dextrose 5%/sodium chloride 0.9%, Ringer's lactate/dextrose 5%, or Normosol-M and dextrose 5% may be stored in a refrigerator for 96 h. Discard pharmacy bulk packages no later than 4 h after initial closure puncture. Store Galaxy containers at or below −4°F. Thawed containers may be kept for 72 h at room temperature or 30 days under refrigeration. Do not refreeze.Oral
Store at 59° to 86°F.
Drug InteractionsAminoglycosides, amphotericin B, bacitracin, cisplatin, colistin, polymyxin B, viomycin
May increase risk of nephrotoxicity and/or neurotoxicity. Monitor renal function and serum drug concentrations with coadministration.Anesthetics
Increased risk of hypersensitivity and infusion-related reactions. Give vancomycin as a 60-min infusion prior to anesthetic induction.Indomethacin
May increase vancomycin toxicity in neonates. Closely monitor.Methotrexate
May increase methotrexate toxicity. Monitor renal function and adjust methotrexate dosage as needed.Nondepolarizing muscle relaxants
Neuromuscular blockade may be enhanced. If coadministration cannot be avoided, monitor neuromuscular function closely, titrate the dose of nondepolarizing muscle relaxant, and be prepared to provide mechanical respiratory support as needed.
Headache (7%); fatigue (5%); dizziness, vertigo (rare).
Drug rash with eosinophilia and systemic symptoms, exfoliative dermatitis, pruritus, rash, Stevens-Johnson syndrome, TEN, urticaria, vasculitis (postmarketing).
Hearing loss; tinnitus (rare).
Nausea (17%); abdominal pain (15%); diarrhea, vomiting (9%); flatulence (8%); antibiotic-associated colitis.
Urinary tract infection (8%); nephrotoxicity including increased blood creatinine, renal failure, and renal impairment (5%); increased BUN; interstitial nephritis, renal failure (rare).
Reversible agranulocytosis; eosinophilia, reversible neutropenia, thrombocytopenia (postmarketing).
Hypokalemia (13%); pyrexia (9%); back pain, peripheral edema (6%); anaphylaxis, chills, drug fever, hypotension, red man syndrome (flushing of the face, neck, upper chest, and extremities) (postmarketing).
Perform serial monitoring of renal function. Monitor auditory function. Monitor leukocyte count in patients who are on prolonged therapy or who are receiving concomitant drugs that may cause neutropenia. Monitor vancomycin trough concentrations prior to next dose at steady-state concentrations (approximately after the fourth dose) and maintain above 10 mg/L. Ensure that minimum trough concentrations are higher (at least 15 to 20 mg/L) in patients with complicated infections.
Category C (injection); Category B (oral).
Excreted in breast milk.
Confirming serum levels is recommended.
Adjust dosage schedules. Elderly patients may take longer to respond and may require a prolonged course of oral vancomycin.
Anaphylactoid reactions may occur.
Dosage adjustments required; use with caution.
Special Risk Patients
Use with caution in patients with preexisting hearing loss, patients receiving ototoxic or nephrotoxic drugs, and patients receiving drugs that cause neutropenia, nephrotoxicity, and/or neurotoxicity.
Give by secure IV route. May minimize thrombophlebitis by giving slowly as dilute infusion. Chemical peritonitis has been reported following intraperitoneal administration.
C. difficile –associated diarrhea
Has been reported with nearly all antibacterials, including vancomycin injection, and may range in severity from mild diarrhea to fatal colitis.
Too rapid IV infusion or bolus administration may be associated with exaggerated hypotension, including shock and cardiac arrest, with or without maculopapular rash over the face, neck, upper chest, and extremities (red man or red neck syndrome).
Has occurred and ranges from increased blood creatinine to renal failure.
Has occurred and may be transient or permanent.
May occur after total dose of 25 g.
Hearing loss, increased BUN, increased serum creatinine, ringing in ears, vertigo.
- Explain that IV medication is given at regular intervals to maintain blood levels.
- Tell patients to report hearing loss, ringing in ears, or vertigo to their health care provider.
- Explain signs of superinfection (eg, vaginitis).
- Identify symptoms of potential adverse reactions.
- Tell patients to maintain adequate fluid intake.
- Tell patients not to stop taking vancomycin, even if they start to feel better.
