When is vancomycin used and what side effect is it known for?

Vancomycin is a glycopeptide antibiotic reserved for serious infections caused by gram-positive bacteria resistant to other antibiotics, particularly methicillin-resistant Staphylococcus aureus, or MRSA, and Clostridioides difficile colitis. It works by inhibiting cell wall synthesis at a different site than beta-lactams. The characteristic side effect is "red man syndrome," a histamine-mediated flushing of the face, neck, and trunk caused by rapid intravenous infusion. It is prevented by infusing slowly over at least 60 minutes. ---
