Vancomycin: Antibiotic Uses, Warnings, Side Effects, Dosage

Generic Name: vancomycin

Brand Names: Vancocin, Firvanq

Drug Class: Glycopeptides

What is vancomycin, and what is it used for?

Vancomycin is an antibiotic typically used to treat colon inflammation (colitis) and diarrhea that may occur sometimes after antibacterial treatment, and bacterial infections that are resistant to other antibiotics. Vancomycin belongs to a class of antibiotics known as glycopeptides which are considered the last resort treatment for life-threatening infections of certain gram-positive bacteria.

Gram-positive bacteria are structurally different from gram-negative bacteria, and the types are identified by whether the bacteria get dyed or not in the Gram stain lab test. Oral vancomycin is not very well absorbed systemically and is used only to treat intestinal bacterial infection and inflammation. Intravenous vancomycin is administered to treat other bacterial infections such as endocarditis, skin, bone and blood infections.

Vancomycin kills bacteria by inhibiting the synthesis of the bacterial cell wall, and in addition, prevents bacterial multiplication by altering the cell wall permeability and RNA synthesis. Vancomycin prevents bacterial cell wall growth by binding to d-alanyl-d-alanine (d-Ala-d-Ala) terminus part of peptidoglycan, a molecule of sugar and amino acids and the most essential component of the cell wall.

Vancomycin is effective only for gram-positive bacteria because they lack the additional membrane outside the cell wall that gram-negative bacteria have, which vancomycin cannot penetrate. Gram-positive bacteria can develop resistance to vancomycin by replacing the d-Ala-d-Ala terminus with d-alanyl-d-lactate (d-Ala-d-Lac) or d-alanyl-d-serine (d-Ala-d-Ser).

Vancomycin is active against the following gram-positive bacteria:

  • Staphylococcus aureus (including methicillin-resistant and methicillin-susceptible [MRSA and MSSA] isolates)
  • Clostridium difficile
  • Coagulase negative staphylococci (including S. epidermidis and methicillin-resistant isolates)
  • Corynebacterium spp.
  • Enterococcus spp. (including Enterococcus faecalis)
  • Streptococcus gallolyticus (previously known as Streptococcus bovis)
  • Viridans group streptococci

Vancomycin is used in the treatment of the following types of bacterial infections in both adult and pediatric patients:

  • Staphylococcal enterocolitis
  • Clostridium difficile-associated diarrhea
  • Infective endocarditis
  • Septicemia
  • Bone infections
  • Skin and skin structure infections
  • Lower respiratory tract infections

Off-label uses include:

  • Pre-operative antimicrobial prophylaxis
  • Surgical prophylaxis
  • Bacterial meningitis
  • Other serious infections by susceptible bacteria 

Warnings

  • Do not administer vancomycin to patients with known hypersensitivity to vancomycin
  • Use vancomycin only for a proven or strongly suspected bacterial infection to prevent the development of drug resistant bacteria
  • Oral vancomycin is not effective for systemic infections; use only to treat pseudomembranous colitis due to C. difficile and enterocolitis due to S. aureus
  • Systemic infections are treated with intravenous vancomycin
  • Prolonged vancomycin use may result in bacterial or fungal superinfection
  • Rapid intravenous (IV) infusion can cause “red man syndrome” with symptoms such as red rashes, hives, itching, angioedema and low blood pressure leading to shock and cardiac arrest; reactions are stronger in children and patients who are also concurrently treated with muscle relaxant anesthetics
  • Avoid leakage of vancomycin from the vein (extravasation); can damage tissue
  • Use as prophylaxis for endocarditis only for high-risk patients as per American Heart Association (AHA) guidelines
  • Can be toxic to the ears (ototoxicity) depending on the dosage and duration of treatment; discontinue use if ear symptoms such as tinnitus or vertigo occur
  • Systemic vancomycin can cause acute kidney injury and inflammation, especially when used simultaneously with other drugs that are toxic to the kidneys or in patients with impaired kidney function; use with caution
  • Vancomycin should not be injected into the eye chambers to prevent infection during or before cataract surgery; retinal vascular inflammation and bleeding, with vision loss have been reported
  • Severe, life-threatening skin reactions can occur with vancomycin use; discontinue promptly at the first sign of such reactions
  • Single-dose flexible bags are not recommended for use during pregnancy because it contains polyethylene glycol (PEG) 400 and N-acetyl-D-alanine (NADA), which caused fetal malformations in animal reproduction studies; if vancomycin is needed during pregnancy, use other available formulations of vancomycin

The drug interactions listed above are not all of the possible interactions or adverse effects. For more information on drug interactions, visit the RxList Drug Interaction Checker.

It is important to always tell your doctor, pharmacist, or health care provider of all prescription and over-the-counter medications you use, as well as the dosage for each, and keep a list of the information.

Check with your doctor or health care provider if you have any questions about the medication.

Pregnancy and breastfeeding

  • Oral vancomycin use may be acceptable during pregnancy; use intravenous vancomycin during pregnancy if benefits outweigh potential risks.
  • Some formulations of vancomycin injection which contain polyethylene glycol (PEG 400) and N-acetyl D-alanine (NADA) are not recommended for use during the first or second trimester of pregnancy; PEG 400 and NADA caused fetal malformations in animal reproduction studies.
  • Systemic absorption from oral vancomycin is low and it is not known if it is present in breast milk; use with caution.
  • Vancomycin is excreted in breast milk with intravenous administration; because of the potential for adverse events, a decision should be made whether to discontinue nursing or to discontinue the drug, taking into account the importance of the drug to the mother.

What else should I know about vancomycin?

  • Antibacterial drugs including vancomycin are used only to treat bacterial infections; they are ineffective for viral infections
  • Take vancomycin exactly as prescribed; skipping doses or not completing the full treatment course can reduce its efficacy and cause antibiotic-resistant bacteria to develop
  • Keep vancomycin out of reach of children
