My husband, Chuck, who is currently on hemodialysis at the center, had two infusions of Vancomycin for his MRSA. Yesterday he had what appeared to be symptoms of a reaction to the medication. His symptoms were itching at the port site and under his arm, low blood pressure, dizziness, and nausea. Apparently this can sometimes happen if infused too quickly, although he does not believe that was his situation. The reaction can take place 7 to 10 days after administering. Other symptoms, which he did not have, are a rash and shortness of breath.
