Published: July 22, 2026Updated: July 22, 2026

Vancomycin is a glycopeptide antibiotic used to treat serious gram-positive bacterial infections, particularly those caused by methicillin-resistant Staphylococcus aureus (MRSA) and other resistant organisms. It is reserved for serious infections due to its importance in treating resistant pathogens.

Overdose information

Important overdose information
Toxic dose: Single dose exceeding 5 grams may cause serious toxicity, particularly nephrotoxicity and ototoxicity
Chronic overdose: Prolonged serum trough levels above 20 mcg/mL may lead to cumulative nephrotoxicity and ototoxicity
Immediate actions
Discontinue vancomycin infusion immediately, initiate supportive care, monitor renal function and serum vancomycin levels, consider hemodialysis in severe cases
Antidote
No specific antidote(Supportive care is primary treatment; hemodialysis may remove vancomycin in severe overdose)

Administration routes

Serious gram-positive infections including MRSA bacteremia, endocarditis, bone and joint infections, pneumonia, and skin/soft tissue infections. Oral formulation used for Clostridioides difficile colitis.

Binds to D-Ala-D-Ala termini of peptidoglycan precursors, blocking bacterial cell wall synthesis by preventing transglycosylation and cross-linking.

Typically administered intravenously for systemic infections. Requires therapeutic drug monitoring to maintain target levels and minimize nephrotoxicity. Infusion rate must be controlled to prevent red man syndrome. Reserved as a last-line agent to preserve effectiveness against resistant organisms.
