Red Man Syndrome and what causes it?

Explanation:
Red Man Syndrome happens when vancomycin is infused too quickly. The rapid infusion triggers non–IgE-mediated release of histamine from mast cells, causing flushing and erythema on the face, neck, and chest, often with pruritus. It’s a rate-related reaction, not a true allergy, so the fix is to slow the infusion (and consider antihistamines if needed). It’s not due to IV contrast, metoclopramide–induced nausea, or penicillin allergy.
