I am being treated for ABPA with V-fend and Prednisone. Each time I have taken V-fend for 8 weeks or more, I have developed skin rashes or blisters. In 2009, I had a mass in my right lung and took V-fend for more than 8 weeks. I developed blisters on my feet and a mild rash on my chest. In 2010, I had a severe rash on my chest. Right now, I have a rash on the tops of my hands, my chest and my upper back. I'm ending my 8 week series of V-fend and while I am sure when the drug is discontinued, the rash will subside as well. Does anyone else experience these rashes and blisters?
