A client receiving IV vancomycin develops flushing of the face, neck, and upper trunk along with pruritus during the infusion. Vital signs remain stable. Which action should the nurse take first?

  1. ADiscontinue vancomycin permanently and document a drug allergy
  2. BIncrease the infusion rate to complete the dose more quickly
  3. CSlow the infusion rate and notify the provider
  4. DStop the infusion and administer epinephrine for anaphylaxis
Show answer & explanation

Correct answer: C. Slow the infusion rate and notify the provider

This presentation is consistent with 'red man syndrome,' a histamine-mediated reaction related to rapid vancomycin infusion rather than a true allergy. The appropriate action is to slow the infusion rate and notify the provider, since slowing administration often resolves the symptoms.

Why the other options are wrong

  • A. This reaction is rate-related, not a true allergy, so vancomycin may still be given more slowly in the future.
  • B. Increasing the rate would worsen the histamine release reaction.
  • D. Vital signs are stable and this is not anaphylaxis, so epinephrine is not indicated.

Red Man Syndrome (Vancomycin)

A histamine-release reaction to rapid vancomycin infusion causing flushing, pruritus, and rash on the face, neck, and upper trunk—not a true drug allergy.

  • Caused by rapid infusion, not IgE-mediated allergy
  • Managed by slowing the infusion rate
  • Vancomycin should typically infuse over at least 60 minutes

Memory trick: 'Red Man = Ran too fast' — slow it down
