Red Man Syndrome presents with?

Red Man Syndrome presents with?

• A. Rash on legs only.
• B. Hypothermia.
• C. Flushing, erythema, and pruritus on face, neck, and chest.
• D. Severe diarrhea.

Answer: (C)

Red Man Syndrome is a histamine-mediated reaction to rapid IV vancomycin infusion. It causes flushing and erythema with itching, most commonly on the face, neck, and upper chest, and can be accompanied by mild cardiovascular changes like hypotension or tachycardia. This presentation matches the described symptoms best, since the reaction is due to histamine release from the infusion rather than a true IgE-mediated allergy. Management focuses on slowing the infusion rate (typically aiming for at least 60 minutes for vancomycin) and treating symptoms with antihistamines if needed, with close monitoring. The other options don’t fit this infusion-related pattern: a rash only on the legs isn’t characteristic of Red Man Syndrome, hypothermia isn’t part of this reaction, and severe diarrhea isn’t the typical manifestation.
