VANCOMYCIN AND RED MAN SYNDROME
mg IV)
Monitor vital signs and provide supportive care as needed. If symptoms persist, consider additional interventions such as corticosteroids.
3. PREVENTION OF RED MAN SYNDROME
To minimize the risk of red man syndrome, the following preventive measures should be taken:
1. Administer vancomycin slowly, typically over at least 60 minutes for doses greater than 1g.
2. Consider premedication with antihistamines for patients with a history of RMS or those at higher risk.
3. Monitor patients closely during the infusion, especially during the first dose.
4. Educate patients about the potential symptoms of RMS and the importance of reporting any reactions immediately.
By following these guidelines, healthcare providers can help reduce the incidence of red man syndrome and ensure safer administration of vancomycin.mg IV)
Infuse fluids if hypotension occurs
When symptoms decrease, resume vancomycin infusion after 4 hours or more. If subsequent doses are given, use antihistamines before each vancomycin infusion and infuse vancomycin over 4 hours, monitoring blood pressure during the infusion
*Diphenhydramine: the medication at the hospital is commercially named Dimedrol
3. PREVENTION OF RED MAN SYNDROME WHEN USING VANCOMYCIN
To minimize adverse reactions related to infusion, each dose of vancomycin should be infused over at least 60 minutes at a maximum rate of 10 mg/min and alternate infusion sites. To reduce the risk of RMS, a dose of 1g is typically recommended to be infused over 2 hours. According to a study, infusing vancomycin (1 g) over 2 hours significantly reduces the frequency, severity of RMS, and the amount of histamine released into the plasma compared to infusing over 1 hour. However, RMS has also been reported with slow vancomycin infusions. Patients should be closely monitored, and vancomycin should be stopped immediately if hypotension, chest pain, muscle pain, or any adverse events occur during the infusion.

GUIDELINES FOR DILUTING VANCOMYCIN INFUSION SOLUTION For a vial containing 500mg of vancomycin: – Reconstitute the lyophilized powder with 10ml of sterile water for injection. – Dilute with at least 100ml of solvent (0.9% NaCl or 5% glucose) to achieve a concentration of 2.5g/L to 5.0g/L and infuse continuously for at least 60 minutes For a vial containing 1g of vancomycin**: – Reconstitute the lyophilized vancomycin powder with 20ml of sterile water for injection. – Dilute with at least 200ml of solvent (0.9% NaCl or 5% glucose) to achieve a concentration of 2.5g/L to 5.0g/L and infuse continuously for at least 100 minutes. Note: after dilution, it should be used immediately, can be stored at 2-8 degrees Celsius for 24 hours |
**Vancomycin 1g: at the hospital, it is commercially named Voxin 1g
