To all suffering from itching--ME TOO! And I was told to stop the Rifampin as well. I am currently only on 2 meds and that unsightly raised rash has gone BUT I have small red rashes on my stomach and back now and this rash really itches. I went to see the dermatologist for the first outbreak and she took a biopsy which revealed it was a reaction from medication and since my ID doctor felt that rifampin was the lesser of the three we cut that one out. Frankly I think all antibiotics taken long term [as we do] causes all sorts of other problems for our bodies...I wish I had a solution to offer those of us itching but alas....nothing to suggest.
