Vancomycin — Uses, Dosage, Side Effects & Safety

Drug class: Glycopeptide antibiotic

Overview

Vancomycin is a powerful antibiotic used to treat serious bacterial infections, especially those caused by Gram-positive bacteria that are resistant to other antibiotics, such as methicillin-resistant Staphylococcus aureus (MRSA) and certain types of enterococci. It is often reserved for severe infections like bloodstream infections, bone and joint infections, endocarditis, and severe skin or soft tissue infections. Vancomycin works by stopping the growth of bacteria. It does this by interfering with the bacteria's cell wall formation, which is essential for their survival. For some infections, vancomycin is given by injection, while for certain gut infections (like Clostridioides difficile), it is taken by mouth. Key points for patients: Vancomycin should only be used as prescribed by your healthcare provider. Complete the full course, even if you feel better. Report any unusual side effects, especially hearing changes, rash, or difficulty urinating.
