Slow or stop the infusion and report flushing, rash, or hypotension (red man syndrome).

Test yourself first: 5 questions
Question 1 of 5
A nurse is caring for a client on contact precautions with a Clostridioides difficile infection who is prescribed oral vancomycin. The client asks why the IV form is not being used. Which response by the nurse is correct?
Answer: A. For C. difficile colitis, oral vancomycin is used because it stays in the gut lumen and acts locally on the intestinal bacteria; IV vancomycin does not achieve adequate intestinal concentrations. Oral vancomycin is poorly absorbed systemically, which is exactly why it is effective here. It is not about cost, allergy testing, or being a weaker form of the drug.
Question 2 of 5
A client is prescribed IV vancomycin for a methicillin-resistant Staphylococcus aureus (MRSA) infection. Which laboratory value is most important for the nurse to monitor to evaluate for nephrotoxicity?
Answer: B. Vancomycin is nephrotoxic, so serum creatinine and BUN must be monitored to detect renal impairment. Trough levels are also drawn, but for nephrotoxicity specifically the creatinine is the key marker. Hemoglobin, sodium, and platelets are not the primary concern with vancomycin.
Question 3 of 5
During an IV vancomycin infusion, the client develops flushing and a red rash on the face and neck. The nurse should:
Answer: B. Flushing/erythema ('red man/red person syndrome') results from infusing vancomycin too fast. Stop or slow the infusion; it is rate-related, not a true allergy.
Question 4 of 5
A client receiving IV vancomycin develops flushing and redness of the face and neck during infusion. The nurse should:
Answer: B. Flushing of the face/neck during vancomycin is 'red man syndrome' from too-rapid infusion. Slow or stop the infusion; it is rate-related, not a true allergy.
Question 5 of 5
A nurse is administering IV vancomycin and notes the client develops flushing and erythema of the face, neck, and upper torso during the infusion. Which action should the nurse take first?
Answer: B. Flushing of the upper body (vancomycin infusion reaction, formerly red man syndrome) results from histamine release due to rapid infusion. The first action is to slow or stop the infusion. The drug is then restarted at a slower rate; antihistamines may be given. Stopping the drug entirely is not required if the rate is corrected.
Keep the streak going with more questions like these, each with a full rationale.
What is vancomycin?
It has a narrow therapeutic range and requires trough monitoring. Key principle: infuse slowly to prevent vancomycin flushing (red man) syndrome and monitor for kidney and ear toxicity.
Key points to remember
- It treats MRSA and other resistant gram-positive infections; oral vancomycin treats C. difficile.
- Rapid IV infusion causes vancomycin flushing syndrome (red man syndrome): flushing, rash, and hypotension.
- It is nephrotoxic and ototoxic, especially with high levels or prolonged use.
- Trough levels are drawn 30 minutes before the next dose to guide dosing and safety.
- It is infused over at least 60 minutes to prevent infusion reactions.
Nursing priorities
- Infuse over at least 60 minutes and slow the rate if flushing occurs.
- Monitor trough levels and adjust dosing to stay in therapeutic range.
- Monitor renal function (BUN, creatinine) and urine output for nephrotoxicity.
- Assess hearing and report tinnitus for ototoxicity.
- Monitor for signs of infusion reaction during administration.
Labs & values
Patient teaching
- Report itching, rash, or flushing during the infusion.
- Report any change in hearing or ringing in the ears.
- Complete the full course and keep lab appointments for level monitoring.
Red flags: report now
- Slow or stop the infusion and report flushing, rash, or hypotension (red man syndrome).
- Report rising creatinine or decreased urine output (nephrotoxicity).
- Report tinnitus or hearing loss (ototoxicity).
