Derm told me I had to completely stop all meds, meaning the telaprevir, (vertex), riba and peg. She prescribed Prednisone
with a taper schedule
of 21 days, however, my study doctor allowed me to stay on all meds for an additional day or two to see if the prednisone would work. He was very clear that if the prednisone didn't clear it up quickly, I had to completely come off of the study, including SOC drugs.
