Can either vancomycin or sepsis cause sudden peeling on my buttocks? i'm on 1.5g of i.v. vanc, 2/day, due to sepsis and/or from an infected port.

Yes, but....: An allergy to vancomycin can cause this reaction. However, depending on the timing of the original infection, peeling skin can be from the original infection. A visit to the doctor is in order....

Yes: Yes in fact this is not an uncommon occurance and if you are recovering well is not of concern. It is your bodies way of healing itself.
